    Full Text Available Context: Chylous ascites is the accumulation of milky chyle in the peritoneal cavity. Chylous ascites has been reported after surgeries like abdominal aortic aneurysm repair, radical gastrectomy, duodenectomy, nephrectomy and Wilm′s tumor resection. Our literature search did not reveal any reports of chylous ascites after a gastric ulcer resection. We report about an elderly woman with a rare complication of chylous ascites after an emergent surgery for a perforated gastric ulcer. Case Report : A 70-year-old woman developed sudden respiratory distress on 5 th post-operative day after an elective C3-C7 cervical discectomy and fusion. Her past medical history was significant for cervical spondylosis. The Computed Tomography (CT scan of the chest revealed air under the diaphragm suspicious for hollow viscus perforation. She underwent an emergent surgery for drainage of hematoma in the neck along with an emergent laparotomy to repair a large perforated gastric ulcer distal to the gastro-esophageal junction. The patient had worsening of abdominal distention on 4 th post-operative day. The CT scan of abdomen showed fluid collection in the abdomen. The abdominal drain revealed large amount of serous milky fluid at the rate of 1500 ml per day. The fluid analysis showed that the triglyceride level was 170 mg/dl and cholesterol level was 15 mg/dl. The fluid cultures did not grow any organism. She responded to treatment with octreotide and a diet of medium chain triglyceride oil. Conclusion: Any obstruction or damage to the lymphatic channels results in chylous ascites. Lymphomas, metastatic malignancies, and abdominal surgeries commonly cause chylous ascites. Ascitic fluid triglyceride level greater than 110 mg/dl is diagnostic of chylous ascites. Chylous ascites is a rare complication of a peptic ulcer resection which can be managed effectively with octreotide.

    Ultrasonography detects ascites easily even in trace amounts. 80% of the cases are caused by hepatic disease, in the remaining 20% cancer, inflammation, pancreatic, renal, or cardiac disease can be found. The underlying disease should be investigated by few inexpensive laboratory test from serum, urine and ascites and by abdominal sonography. Hepatic ascites is caused by portal hypertension and disturbances of humoral factors. Sodium retention, peripheral, vasodilation, hyperdynamic circulation and progressive renal vasoconstriction lead to a stepwise deterioration of patients condition. Treatment with diuretics (furosemide, torsemide, or xipamide and spironolactone) and sodium-restriction (peritoneo-venous shunt is restricted to rare indications. In the future, new drugs such as antagonists of endothelins or of the antidiuretic hormone may offer new therapeutic options. PMID:9064726

    Ascites is a common complication of liver cirrhosis associated with a poor prognosis. The treatment of ascites requires dietary sodium restriction and the judicious use of distal and loop diuretics, sequential at an earlier stage of ascites, and a combination at a later stage of ascites. The diagnosis of refractory ascites requires the demonstration of diuretic non-responsiveness, despite dietary sodium restriction, or the presence of diuretic-related complications. Patients with refractory ascites require second-line treatments of repeat large-volume paracentesis (LVP) or the insertion of a transjugular intrahepatic portosystemic shunt (TIPS), and assessment for liver transplantation. Careful patient selection is paramount for TIPS to be successful as a treatment for ascites. Patients not suitable for TIPS insertion should receive LVP. The use of albumin as a volume expander is recommended for LVP of >5-6 L to prevent the development of circulatory dysfunction, although the clinical significance of post-paracentesis circulatory dysfunction is still debated. Significant mortality is still being observed in cirrhotic patients with ascites and relatively preserved liver and renal function, as indicated by a lower Model for End-Stage Liver Disease (MELD) score. It is proposed that patients with lower MELD scores and ascites should receive additional points in calculating their priority for liver transplantation. Potential new treatment options for ascites include the use of various vasoconstrictors, vasopressin V(2) receptor antagonists, or the insertion of a peritoneo-vesical shunt, all of which could possibly improve the management of ascites.

    Full Text Available Even ascites appears mainly as sign of portal hypertension in patiens with liver cirrhosis, in some case depends on a different lying condition such as right congestive heart failure, peritoneal carcinomatosis or tuberculosis. In these cases, paracentesis represents the key tool for diagnosis. We report a case of cardiac ascites in a 71-years-old woman who developed in four-month an abdominal distension. Preliminary exams showed exudative ascites related to portal hypertension, a pelvic mass with caseous apparence, and inflammatory status ad an elevation of CA-125. Successive evaluation exluded peritoneal carcinomatosis or tuberculosis, underlyng a tricuspidal regurgitation. The literature on ascites has also been reviewed.

    Ascites is the most common complication of cirrhosis. Ascites develops as a consequence of an abnormal splanchnic vasodilation with reduction of effecting circulating volume and activation of endogenous vasoconstrictors system causing salt and water retention. Patients with ascites have a high risk to develop further complications of cirrhosis such as hyponatremia, spontaneous bacterial peritonitis and acute kidney injury resulting in a poor survival. In recent years, new studies helped a better understanding of the pathophysiology of ascites and acute kidney injury in cirrhosis. Furthermore, new diagnostic criteria have been proposed for acute kidney injury and hepatorenal syndrome and a new algorithm for their management has been recommended with the aim of an early diagnosis and treatment. Herein we will review the current knowledge on the pathophysiology, diagnosis and treatment of ascites and acute kidney injury in patients with cirrhosis and we will identify the unmet needs that should be clarified in the next years.

    Full Text Available Chylous ascites is a rare clinical entity. In infancy it is less commom still. The etiology of most of them is usually congenital or idiopathic; trauma is a less frequent cause. It has been implicated in about 10% of all cases 1-5. There have been less than one hundred cases published in the English literature, including 12 in children. We report a pediatric case of chylous ascites as a result of blunt abdominal trauma managed by ligation of the lymphatic leak.

    Full Text Available ABSTRACT: Pseudomyxoma peritonei (PMP is a condition characte rized by the accumulation of mucinous material in the peritoneal cavity (gela tinous ascites. Pseudomyxoma peritonei is an uncommon condition in which mucinous ascites causes progressive abdominal distension and gastrointestina l dysfunction. We present a case of 44 year old female who presented with gradually progres sive abdominal distension since 6 months. An ascitic tap was performed and the fluid wa s sent for cytological study. Cytology showed pools of acellular mucin. On laparotomy there was mucinous material in the abdomen that was evacuated. Appendix and omentum were found t o be thickened, hence appendicectomy was done and omental biopsy taken. Histopathological diagnosis of well differentiated mucinous adenocarcinoma of appendix with rupture and mucinous ascitis was made.

    Full Text Available Fetal ascite is defined as fluid accumulation in peritoneal cavity. It can be seen as isolated disease or an early sign of hydrops fetalis. Once fetal ascite is detected, a careful examination for hydops fetalis and possible underlying disease is necessary, since its prognosis and treatment depends mostly on the cause. Non-immunologic fetal ascite is an uncommon problem occurring for many reasons, such as urinary tract obstruction, congenital infections, genetic and metabolic diseases, gastrointestinal diseases and cardiovascular diseases. Here in this report we present two isolated fetal ascite that occurred secondary to cardiac diseases.

    1. B- and M-mode echocardiography was used to compare cardiac function in broilers with spontaneous ascites syndrome with that of normal chickens. 2. Thirty ascitic chickens and 15 normal chickens aged three, 4, 5, and 6 weeks from the same flock (180 birds in total) were examined. They were restrained gently in a natural standing position, and echocardiographs were obtained from a 7.0-MHz linear transducer placed on the left pectoral apterium. Indices of cardiac structure and functioning were calculated from the echocardiographs, and some were normalised to body weight. Heart rate was also measured. 3. All cardiac structural indices in both ascitic and normal chickens increased with age. Compared with normal chickens, right ventricular diameter at the end of systole in ascitic chickens was greater at 4, 5 and 6 weeks of age. Ventricular septal thickness at the end of both systole and diastole was greater in ascitic chickens at 5 and 6 weeks. Left ventricular free wall thickness at the end of diastole was less in ascitic chickens at 3 weeks. However, all the structural indices decreased with age after normalisation with body weight. 4. The heart rate of ascitic chickens was lower at 4, 5 and 6 weeks. Normalised left ventricular fractional shortening was lower in ascitic chickens at 4, 5 and 6 weeks, as was normalised right ventricular fractional shortening. Incrassation of the ventricular septum (Delta T), which changed little in normal chickens, was less at 4, 5 and 6 weeks in ascitic chickens. Left ventricular fractional shortening, right ventricular fractional shortening and Delta T were all negatively correlated with ascites heart index at all ages. 5. Taken together the results suggest heart failure of both ventricle, but that right ventricular dysfunction is more extensive than left ventricular dysfunction. We suggest that secondary pulmonary hypertension would result in these ascitic chickens due to volume overload. PMID:17190684

    2014-01-01

    Full Text Available Chylous ascites is an uncommon form of ascites characterized by milky-appearing fluid caused by blocked or disrupted lymph flow through chyle-transporting vessels. The most common causes of chylous ascites are therapeutic interventions and trauma. In this report, we present four cases of chylous ascites following robot-assisted surgery for endometrial staging and the treatment strategies that we used. After retroperitoneal lymph node dissection, leaving a drain is very useful in diagnosing chylous ascites and observing its resolution; furthermore, the use of octreotide in conjunction with TPN appears to be an efficient treatment modality for chylous ascites and should be considered before any invasive intervention.

    An African pygmy hedgehog (Atelerix albiventris) was diagnosed as chylous ascites with biliary cirrhosis. Abdomenocentesis revealed a milky fluid with a 324 mg/dl triglyceride level. On serum biochemical examination, the hedgehog had hypoalbuminemia, hypoglycemia, and high blood urea nitrogen. There was no cytologic or genomic evidence of infection, and a blood culture was negative. Histopathologic examination revealed a liver with proliferative bile ducts that were often surrounded by prominent septa of fibrous connective tissue. In the area of ductular reaction, proliferative cells positive for CD66, an embryogenic antigen of epithelial cells, were revealed. The potential association between chylous ascites and liver cirrhosis is undetermined but could be an aspect of future study. This is the first description of chylous ascites in a hedgehog.

    Full Text Available Abstract Although the factors involved in cirrhotic ascites have been studied for a century, a number of observations are not understood, including the action of diuretics in the treatment of ascites and the ability of the plasma-ascitic albumin gradient to diagnose portal hypertension. This communication presents an explanation of ascites based solely on pathophysiological alterations within the peritoneal cavity. A quantitative model is described based on experimental vascular and intraperitoneal pressures, lymph flow, and peritoneal space compliance. The model's predictions accurately mimic clinical observations in ascites, including the magnitude and time course of changes observed following paracentesis or diuretic therapy.

    Full Text Available A comparison was made of the clinical findings of 59 patients with liver cirrhosis (LC accompanied with hepatocellular carcinoma (HCC (of which 35 had ascites and 24 did not at the time of admission and 164 patients with LC, but without HCC (of which 39 had ascites and 125 did not. HCC patients were older and more often had hepatomegaly, vascular spider and pleural effusion than LC patients. Ascites was more frequently observed in HCC than in LC patients when the serum albumin level and the indocyanine green disappearance rate were relatively well maintained and when peripheral edema was absent. There was no difference in the ascitic protein concentration between LC and HCC patients. Malignant cells were detected in ascites only in 14% of the HCC patients. These facts indicate the presence of ascites-inducing factors in HCC patients which have no direct relation to serum colloid osmotic pressure and effective hepatic blood flow. Almost all of the HCC patients with ascites (96% died with ascites, whereas 54% of the LC patients with ascites recovered from the ascitic condition.

    Ascites is the most frequent complication of hepatic cirrhosis and its appearance brings a reduction of survival. The treatment aims to mobilise the intraperitoneal liquid and to prevent its reaccumulation. The first step of treatment includes rest in bed, a hyposodic and spironolactone diet, alone or in combination with furosemide or torasemide. However, 10-20% of patients do not respond to treatment or develop adverse effects that limit its use, which is termed refractory ascites. These patients must be considered as possible candidates for a liver transplant and, when this is not possible, the chosen treatment is total paracentesis with an intravenous infusion of albumin. In patients who do not tolerate paracentesis, or who require its realisation with great frequency, other therapeutic options can be evaluated, such as surgical anastomoses, intrahepatic portosystemic percutaneous derivation and, in the final instance, peritoneo-venous shunt.

    Malignant ascites is a frequent complication in oncological diseases. There are no standard therapies for any primary tumour. We report the case of a woman, aged 49 years at the time of primary diagnosis, who suffered from recurrent ascites resulting from liver metastasis of breast cancer. Based on the literature and former experience of our department, mistletoe extract was repeatedly applied intraperitoneally at the occasion of decompressive punctures. The further course of the disease suggests a significant role of mistletoe in achieved symptom control, which also resulted in a considerable improvement in quality of life. The mistletoe solution was well tolerated. Relevant mechanisms of action in addition to the well-known immunomodulating properties of mistletoe could be direct cytotoxic and adjuvant effects to the concomitantly administered chemotherapy of carboplatin/paclitaxel.

    2008-04-01

    Broiler chickens are intensively selected for productive traits. The management of these highly productive animals must be optimal to allow their full genetic potential to be expressed. If this is not done, inefficient production and several metabolic diseases such as ascites become apparent. The causes of the ascites are multifactorial but diet and, particularly, interactions between diet, other environmental and genetic factors play an important role. The relatively high heritability estimates for ascites-related traits and the significance of maternal genetic effects for most of the traits indicate that direct and maternal genetic effects play an important role in development of the ascites syndrome. An imbalance between oxygen supply and the oxygen required to sustain rapid growth rates and high food efficiencies causes ascites in broiler chickens. Because of the relationship to oxygen demand, ascites is affected and/or precipitated by factors such as growth rate, altitude (hypoxia) and environmental temperature. As the high metabolic rate (fast growth) is a major factor contributing to the susceptibility of broilers to ascites, early-age feed or nutrient restriction (qualitative or quantitative) or light restriction in order to slow down the growth rate seem practically viable methods, since final body weight is not compromised. Manipulation of the diet composition and/or feed allocation system can have a major effect on the incidence of ascites. Optimization of the house temperature and ventilation in cold weather seem helpful practices to decrease ascites incidence. PMID:18393088

    Chylous ascites is a rare form of ascites and generally associated with a poor outcome since it is often secondary to neoplasms. Its true incidence is not well established in the general medico-surgical population. Any source of lymph vessels obstruction or leakage can potentially cause chylous effusions in the peritoneal or retroperitoneal cavities. Any type of cancer and lymph node involvement may be associated with this uncommon type of ascites. Traumatic, and mainly surgical, vessels leakage is the second most common source of chylous effusions. Other even more rare underlying conditions have been described as leading to chyloperitoneum. Large fluid volume losses together with proteins, and lymphocytes can induce additional morbidity in a previously debilitated population or severely ill patients. This includes organ dysfunction related to volume and electrolytes losses, but mainly secondary infections due to impaired immunity by antibodies and lymphocytes depletion. Even if a vast majority of chylous effusions shall heal spontaneously, early and full treatment has to be initiated in order to reduce morbidity and mortality associated with this condition. Adapted oral diet is to be introduced to reduce lymph flow. Low lipid, high medium-chain triglycerides alimentation is the first measure to implement. Total parenteral nutrition is to be reserved to failures of oral diet. In addition, paracentesis is indicated to improve patient comfort, reduce intra-adbominal pressure and secondary renal dysfunction. Somatostatin analogues have been demonstrated to be effective in reducing lymphorragia and may be proposed prior to consider the surgical approach. Direct lymph vessels ligation can be indicated for large lymph vessels leakage demonstrated by radiologic techniques and when medical treatment has failed. Peritoneo-venous shunt becomes a less common technique in refractory chylous effusion because of its high morbidity. Herein, the other causes of chylous effusions

    Malignant ascites affects approximately 10% of patients with gastric cancer (GC), and poses significant difficulties for both patients and clinicians. In addition to the dismal general condition of affected patients and the diversity of associated complications such as jaundice and ileus, problems in assessing scattered tumors have hampered the expansion of clinical trials for this condition. However, the accumulation of reported studies is starting to indicate that the weak response to treatment in GC patients with malignant ascites is more relevant to their poor prognosis rather than to the ascites volume at diagnosis. Therefore, precise assessment of initial state of ascites, repetitive evaluation of treatment efficacy, selection of suitable treatment, and swift transition to other treatment options as needed are paramount to maximizing patient benefit. Accurately determining ascites volume is the crucial first step in clinically treating a patient with malignant ascites. Ultrasonography is commonly used to identify the existence of ascites, and several methods have been proposed to estimate ascites volume. Reportedly, the sum of the depth of ascites at five points (named "five-point method") on three panels of computed tomography images is well correlated to the actual ascites volume and/or abdominal girth. This method is already suited to repetitive assessment due to its convenience compared to the conventional volume rendering method. Meanwhile, a new concept, "Clinical Benefit Response in GC (CBR-GC)", was recently introduced to measure the efficacy of chemotherapy for malignant ascites of GC. CBR-GC is a simple and reliable patient-oriented evaluation system based on changes in performance status and ascites, and is expected to become an important clinical endpoint in future clinical trials. The principal of treatment for GC patients with ascites is palliation and prevention of ascites-related symptoms. The treatment options are various, including a

    Full Text Available Abstract Introduction Chylous ascites may result from diverse pathologies. Ascites results either due to blockage of the lymphatics or leak secondary to inadvertent trauma during surgery. Case presentation We report the first case of chylous ascites following radical nephrectomy for a renal cell carcinoma involving the right half of a crossed fused renal ectopia. The patient was managed conservatively. Conclusion Post-operative chylous ascites is a rare complication of retroperitoneal and mediastinal surgery. Most cases resolve with conservative treatment which aims at decreasing lymph production and optimizing nutritional requirements along with palliative measures. Refractory cases need either open or laparoscopic ligation of the leaking lymphatic channels. A review of the current literature on the management of post-operative chylous ascites is presented.

    Full Text Available Two hundred and forty male Cobb broilers were used to study the reasons of causing ascites. The results showed that cold ambient temperature could induce ascites (33.89% vs. 2.50% and significantly increase triiodothyronine (T3, but reduce thyroxine (T4 concentrations in plasma (p+, but low concentrations of T3 and T4 in the plasma (p<0.05. The lower body weight and higher relative heart, lung and liver weight of the ascitic broilers demonstrated the metabolic disarrangement. When ascites occurred, hematocrit in blood increased significantly (p<0.05. The mash feed could reduce body weight and the onset of ascites, compared with the pellet feed.

    BACKGROUND The clinical manifestations of amyloidosis depend on the type of insoluble protein as well as the location of amyloid deposits in tissues or organs. In the gastrointestinal tract, the small intestine is the most common site of amyloid deposits, whereas peritoneal involvement and ascites are rare. CASE REPORT We report on a case of ascites due to peritoneal amyloidosis. A 65-year-old patient was admitted to our institution due to anasarca and pulmonary congestion, mimicking heart failure. We started the patient on diuretics and vasodilators. Despite improvement in pulmonary congestion and peripheral edema, his ascites was not reduced. Echocardiogram revealed restrictive cardiomyopathy and a speckle-tracking pattern suggestive of cardiac amyloidosis. Subcutaneous and peritoneal biopsies revealed amyloidosis. CONCLUSIONS Amyloidosis is rare in the peritoneum and is usually asymptomatic. Ascites occurs in only 20% of patients with peritoneal amyloidosis. We searched PubMed using "ascites" and "amyloidosis" and identified only eight case reports of amyloidosis with ascites. Physicians should be particularly careful in heart failure and anasarca cases when ascites is disproportional or not responsive to diuretic treatment. To date, there is no specific treatment for peritoneal amyloidosis. PMID:27353538

    @@ TO THE EDITOR A 61 year old man with cirrhosis and hepatocellular carcinoma developed on the background of chronic hepatitis B was admitted because of acute and gradually intensified right thigh pain and swelling, which, within a few hours, was expanded to his right foot. The patient,due to ascites refractory to diuretics, was almost weekly subjected to large volume paracentesis of ascitic fluid for the last six months; meanwhile he has developed a left inguinal, a right femoral and an umbilical hernia. It should be noted that 48 h before admission, the patient was referred to the emergency room because of dyspnoea and 5 L of ascitic fluid were removed.

    BACKGROUND: Chylous ascites (CA) following pancreatico-duodenectomy (PD) is a rare complication secondary to disruption of the lymphatics during extended retroperitoneal lymph node dissection. The majority of cases do not develop CA, possibly due to patency of the proximal thoracic duct and good collaterals. CA may be due to a consequence of occult obstruction of the proximal thoracic duct by malignant inifltration or tumor embolus. This study was to report the incidence of CA and its outcomes of management. METHODS: A retrospective search of our liver database was performed using the key words "pancreatico-duodenectomy", "chylous ascites" from January 2000 to December 2005. The medical records of CA patients and their management and outcome were reviewed. RESULTS: In 138 patients who had undergone PD in our centre for pancreatic malignancy, 3 were identiifed with CA and managed by abdominal paracentesis. CA resolved in 2 patients with low fat medium chain triglyceride diet alone and 1 patient had total parenteral nutrition (TPN) for persistent CA. Resolution of CA occurred in these 3 patients at a median follow-up of 4 weeks (range 4-12 weeks). Histologically, resected specimen conifrmed pancreatic adenocarcinoma in all the patients. Two patients developed loco-regional recurrences at a median follow up of 8 months (range 6-10 months). And the other was currently disease free at a 10-month follow up. CONCLUSIONS: CA as an uncommon postoperative complication requires frequent paracentesis, prolonged hospital stay, and delayed adjuvant chemotherapy. CA is treated with low fat medium chain triglyceride diet or occasionally TPN is required.

    For the surgical treatment of drug resistant ascites caused by hepatic cirrhosis usually different types of valvular plastic tubes are used, implanted as peritoneo-venous shunts. These shunts drain the ascites into the jugular vein. In the 1st Surgical Department of the Semmelweis University Budapest we have performed 267 peritoneo-venous shunt operations. We introduced a new method using an autolog venous graft with a peritoneo-venous anastomosis, that drains the ascites into the saphenous, then femoral vein. So far we performed 5 such interventions. The early results suggest that sapheno-peritoneal shunt can be successfully used for treatment of ascites. With this operation complications of plastic grafts are avoidable. PMID:11550492

    Steroid cell tumors, not otherwise specified (NOS), are rare ovarian sex cord-stromal tumors with malignant potential. The majority of these tumors produce several steroids, particularly testosterone. Various virilizing symptoms such as hirsutism, temporal balding, and amenorrhea are common in these patients; however massive ascites is an infrequent symptom. A 52-year-old woman with the sudden onset of virilization and massive ascites presented for treatment at Severance Hospital. After clini...

    Phagocytosis of starch granules in ascitic fluid was sought in guinea-pigs 1 to 10 days after i.p. injection of a suspension of starch powder. Starch phagocytosis occurred in 75.9% of control animals with free peritoneal fluid. It probably represents a nonspecific reaction to the particulate nature of starch granules. Guinea-pigs sensitized to starch by nuchal inoculation of an emulsion of Freund's adjuvant and starch showed no increase in frequency or intensity of ascitic starch phagocytosis...

    2002-01-01

    Full Text Available OBJECTIVE: To evaluate the clinical meaning of ascites and the main features of patients with ascites and endomyocardial fibrosis. METHODS: We studied 166 patients with endomyocardial fibrosis (mean age 37 years, 114 women treated over the last 20 years. Ventriculography findings, surgery or necropsy confirmed the diagnosis in all patients. Most patients belonged to New York Heart Association Functional Class III/IV (134, 83.7%. Eighty-one (50.6% had biventricular, 28 (17.5% had right ventricular, and 51 (31.8% had left ventricular involvement. During follow-up, 56 patients died. RESULTS: Ascites was present in 67 (41.8% patients, and right ventricular involvement was present in 59 (88%. In the comparison between patients with or without ascites, those with ascites had higher mortality (49.2% and 24.7%, respectively. Patients with ascites had a higher incidence of edema (95% vs. 43%, hepatomegaly (5.8cm vs. 4.1cm, mean right atrium pressure (19.3 vs. 12mmHg, and final right ventricle diastolic pressure (18.7 vs. 12.9mmHg. Also, patients with ascites had a longer history of illness (5.1 and 3.9 years, respectively and had atrial fibrillation more frequently (44.7% vs. 30.1%. CONCLUSION: Ascites was observed in less than 50% of cases of endomyocardial fibrosis and was associated with greater involvement of the right ventricle and with a longer duration of the disease, thus being a characteristic of a worse prognosis.

  2. Radionuclide Peritoneal Scintigraphy in Patients with Ascites and Pleural Effusion

    International Nuclear Information System (INIS)

    Simultaneous presence of ascites and pleural effusion has been documented in patients with cirrhosis of the liver, renal disease, Meigs' syndrome and in patients undergoing peritoneal dialysis. Mechanisms proposed in the formation of pleural effusion in most of the above diseases are lymphatic drainage and diaphragmatic defect. But sometimes, hepatic hydrothoraxes in the absence of clinical ascites and pleural effusion secondary to pulmonary or cardiac disease are noted. It is not always possible to differentiate between pleural effusion caused by transdiaphragmatic migration of ascites and by other causes based solely on biochemical analysis. Authors performed radionuclide scintigraphy after intraperitoneal administration of 99mTc-labeled colloid in 23 patients with both ascites and pleural effusion in order to discriminate causative mechanisms responsible for pleural effusion. Scintigraphy demonstrated the transdiaphtagmatic flow of fluid from the peritoneum to pleural cavities in 13 patients correctly. In contrast, in 5 patients with pleural effusion secondary to pulmonary, pleural and cardiac diseases, radiotracers fail to traverse the diaphragm and localize in the pleural space. Ascites draining to mediastinal lymph nodes and blocked passage of lymphatic drainage were also clarified, additionally. Conclusively, radionuclide peritoneal scintigraphy is an accurate, rapid and easy diagnostic tool in patients with both ascites and pleural effusion. It enables the causes of pleural effusion to be elucidated, as well as providing valuable information required when determining the appropriate therapy.

  3. Successful radiation treatment of chylous ascites following pancreaticoduodenectomy

    International Nuclear Information System (INIS)

    Chylous ascites is a rare complication following pancreaticoduodenectomy. We report on a case of chylous ascites following pancreaticoduodenectomy in a 76-year-old patient diagnosed with pancreatic cancer. There are various known conservative management strategies, including dietary measures or total parenteral nutrition. Unfortunately, conservative treatment - with total parenteral nutrition and fasting over a period of 4 weeks - was not successful in the present case. The daily output volume of chylous ascites was up to 2500 ml/day. Based on clinical experiences with successfully treated lymphocutaneous fistulas, low-dose radiotherapy was initiated. External beam radiotherapy comprising a total dose of 8.0 Gy to the paraaortic lymph node region was administered in daily single fractions of 1.0 Gy (five fractions/week). Throughout the course of external beam radiotherapy, the secretion of abdominal ascites rapidly decreased, resulting in complete resolution after 2 weeks. There was no clinical evidence of chylous ascites on follow-up. As a result of this experience, we believe that external beam radiotherapy should be considered as an alternative therapy in refractory cases of chylous ascites. (orig.)

    During a 21-month period, 65 consecutive patients admitted with ascites were included in a prospective study of the incidence of spontaneous bacterial peritonitis, and paracentesis was performed on admission. The ascitic fluid was cultured, ascitic leucocytes were counted and pH was measured...... patients with SBP. In contrast to several previous studies, neither ascites pH nor ascites leucocyte counts were any help in obtaining a rapid diagnosis. Survival time of patients with SBP was significantly shorter than of patients without SBP....

    Increased metabolic rates, pulmonary hypertension and cardiac dysfunction are the most important features of the ascites syndrome in broiler chickens. However, the mechanism of cell injury causing the pathogenesis of the syndrome is not clearly understood. Our study aimed to examine the generation of hydroxyl radicals (OH*) in broiler chickens experiencing ascites. The hundred and fifty 1-d-old chickens were purchased from a local hatchery and reared in an open poultry house for 46 d. They were divided at random into three groups and ascites was induced in two groups by exposing them to low temperature or administration of triiodothyronine (T(3)). The third group served as control and was reared normally. Haematological, biochemical and pathological tests were used to determine the incidence of ascites: including total red blood cell (RBC), packed cell volume (PCV), release of alanine transaminase (ALT) and aspartate transaminase (AST) and ratio of right ventricular weight to total ventricular weight (RV/TV). A salicylate hydroxylation method was used to examine the generation of hydroxyl radicals (OH*) in treated groups. TWo hydroxylated salicylic acid metabolites, 2,3- and 2,5-dihydroxy benzoic acid (2,3- and 2,5-DHBA), were measured by HPLC to detect the generation of OH*. An ascites syndrome was observed in T(3) and low-temperature treated groups, as shown by necropsy changes and increases in f RBC, PCV, ALT, AST and the ratio of RV/TV. Concentrations of 2,3- and 2,5-DHBA were increased in groups experiencing ascites compared to control group. It is suggested that reactive oxygen species that is OH* ions, may be involved in the pathogenesis of the ascites syndrome in broiler chickens. PMID:16641033

    1997-07-01

    A 4-year-old girl with optic chiasm glioma (OCG), nonobstructive hydrocephalus and ventriculoperitoneal shunt is described, in whom marked ascites developed. The ascitic fluid was protein-rich and its amount correlated with cerebrospinal fluid (CSF) protein. The CSF protein level and the amount of ascitic fluid were influenced by chemotherapy. Very unusual hypernatremia, up to 190 mEq/l with no associated alteration in mental status, was also found. It is suggested that altered absorption ability owing to the high protein content was the cause of both the nonobstructive hydrocephalus and the ascites. The unusual well being with very high sodium concentrations may have resulted from osmoreceptor dysfunction, presumably caused by hypothalamic involvement as well as by the high CSF protein. This combination of findings may point toward specific characteristics of OCG. In an effort to reduce the amount of the ascitic fluid, a further chemotherapeutic trial may be done, before converting the shunt to the vetriculoatrial system. PMID:9142203

    An 81-year old woman with a history of chronic lymphocytic leukemia (CLL) was admitted with night sweats and abdominal distension. A complete blood count showed hemoglobin 5 g/dL, white blood cell (WBC) count 28.5×109/L and platelets 38.4×109/L. Peripheral blood smear examination showed a large number of smudge cells and lymphocytosis composed of mature-looking lymphocytes with clumped nuclear chromatin. Computed tomography scan demonstrated enlarged cervical, axillary, paraaortic, retroperitoneal and mesenteric lymph nodes with concomitant omental thickening and ascites. Also, the liver and the spleen were enlarged in the presence of multiple ill-defined hypoechoic areas in the latter. Histopathological analysis of the cervical lymph node biopsy was consistent with CLL. Bone marrow examination showed diffuse infiltration of the marrow with small lymphocytes. Analysis of the ascitic fluid revealed an exudate with WBC 1220 cells/mL. Cytocentrifuge preparation of the ascitic fluid showed small mature lymphoid cells containing hyperchromatic nuclei with coarsely granular chromatin. On flow cytometric analysis of the ascitic fluid, expression of CD5, CD19, CD20, CD22, CD23, CD45 and HLA-DR was compatible with a diagnosis of CLL, in accordance with the results of the peripheral blood analysis. The patient was treated with chemotherapy consisting of cyclophosphamide, vincristine and prednisolone but died within one month after development of non-chylous ascites. PMID:23372915

    Full Text Available It is believed that ascitic broilers die of right heart failure caused by pulmonary hypertension, but the underlying mechanisms of right heart failure are unknown. However, recent studies have shown that reactive oxygen species have the ability to damage heart cells. This study aimed to determine the changes of reactive oxygen species in serum and plasma, and the effect of this variation on myocardial cells during broiler ascites. We used hypoxia and a low-temperature method to induce broiler ascites in the fast-growing group. For controls, we treated a slow-growing group of broilers with 70% restricted feeding under the same circumstances as the fast-growing group. The results showed that hypoxia is a more effective and better way to induce broiler ascites than a low-temperature environment and high growth rate. In addition, reactive oxygen species levels were significantly increased in the fast-growing group compared with those in the slow-growing group. This significant increase in reactive oxygen species resulted in myocardial cell apoptosis in the fast-growing group. Our results suggest that cardiomyocyte apoptosis caused by increased reactive oxygen species levels of ascitic broilers is one of the most important reasons for causing heart failure.

    Effects of coenzyme Q10 (CoQ10) supplementation on growth performance and ascites were studied in broilers. One hundred eighty 1-d-old Arbor Acre male broiler chicks were randomly allocated into 3 groups with 6 replicates each. From d 8, the diets were supplemented with CoQ10 at levels of 0, 20, and 40 mg/kg, respectively. From d 15 to 21, all the chicks were exposed to low ambient temperature (15 to 18 degrees C) to induce ascites. Average feed intake, BW gain, and feed conversion ratio of the broilers during 0 to 3 wk, 3 to 6 wk, and 0 to 6 wk were measured. The results showed that there were no influences observed on broilers' growth performance, but the mortality due to ascites was reduced by CoQ10 supplementation (P Ascites heart index (AHI) was significantly decreased by 40 mg/kg CoQ10 supplementation (P ascites mortality in broilers, and 40 mg/kg CoQ10 seems to be more effective than 20 mg/ kg CoQ10.

    Chylous ascites consists of the accumulation of chyle in the peritoneal cavity. Diagnosis is established by cytochemical analysis of the fluid revealing fat globules and high triglyceride content. The majority of cases are caused by pathology that interferes with abdominal retroperitoneal lymphatic drainage. We present two cases of postoperative chylous ascites, one following a bilateral nephrectomy, the other following orthotopic heart transplantation. Treatment is typically conservative with the aim to alleviate abdominal distension and reduce the flow of lymph into the mesenteric lymph nodes. Postsurgical chylous ascites has high cure rate with conservative therapy alone. Therapeutic paracentesis, diuretics, salt restriction, a high-protein, low-fat, mediumchain triglyceride diet, and parenteral nutrition are considered in chronic cases. The effects of longterm paracentesis on patients remains to be seen. In patients requiring renal replacement therapy, removal of chyle during peritoneal dialysis is often attempted. PMID:26997396

    OBJECTIVE: It is currently discussed if beta-blockers exert harmful effects and increase mortality in patients with cirrhosis and refractory ascites. In this study, we provide an overview of the available literature in this field in combination with a retrospective analysis of 61 patients with...... trials (9 trials on propranolol, 1 case-control study and 4 retrospective analyses) were identified. One trial suggested an increased mortality in patients treated with beta-blockers and refractory ascites. The results of the remaining trials were inconclusive. No increase in mortality among beta-blocker......-treated patients was found in the present retrospective analysis. CONCLUSIONS: Treatment with beta-blockers may increase mortality in patients with cirrhosis and refractory ascites. However, the current evidence is sparse and high-quality studies are warranted to clarify the matter....

    Full Text Available Acute chylous ascites is a rarely seen clinical picture, therefore, examination findings are often confused with acute appendicitis. To the best of our knowledge, there is no publication to date showing the occurrence of them together. This study presents the treatment plan for a 25-year-old male patient with both acute chylous ascites and appendicitis. Surgical findings were retrocaecal appendicitis, evident lymphangiectasia in the proximal segment of jejunum, and approximately 3 lt of chylous fluid. An appendectomy was performed and drainage was applied. Low-fat total parenteral nutrition (TPN and octreotide treatment were administered for 7 days postoperatively. We also present a general review of some studies on chylous ascites, which have been published in the English language medical literature since 1910.

  14. Radiologically placed tunneled peritoneal catheter in palliation of malignant ascites

    International Nuclear Information System (INIS)

    The purpose of this study was to evaluate retrospectively the safety and effectiveness of radiologically placed tunneled peritoneal catheter in palliation of malignant ascites. Between July 2005 and June 2009, 41 tunneled peritoneal catheters were placed under ultrasonographic and fluoroscopic guidance in 40 patients (mean age, 55 years; 22 women) who had symptomatic malignant ascites. No procedure related mortality was observed. Major complication occurred in one patient (2.5%) in the form of serious bacterial peritonitis that necessitated catheter removal. Minor complications such as minor bacterial peritonitis, catheter dislodgement, tunnel infection, and catheter blockage occurred in 11 patients (27.5%). The mean duration of survival after catheter placement was 11.8 weeks. All patients expired of their primary malignancies in the follow-up. Radiologically placed tunneled peritoneal catheter is safe and effective in palliation of symptomatic malignant ascites.

    Massive ascites and hepatorenal syndrome (HRS) are frequent complications of liver cirrhosis. Thus, effective therapy is of great clinical importance. This concise review provides an update of recent advances and new developments. Therapeutic paracentesis can be safely performed even in patients with severe coagulopathy.Selected patients with a refractory or recurrent ascites are good candidates for non-surgical portosystemic shunts (TIPS) and may have a survival benefit and improvement of quality of life. Novel pharmaceutical agents mobilizing free water (aquaretics) are currently under test for the therapeutic potential in patients with ascites.Prophylaxis of hepatorenal syndrome in patients with spontaneous bacterial peritonitis is recommended and should be considered in patients with alcoholic hepatitis. Liver transplantation is the best therapeutic option with long-term survival benefit for patients with HRS. To bridge the time until transplantation, TIPS or Terlipressin and albumin are good options. Albumin dialysis can not be recommended outside prospective trials.

    Chylous ascites is an unusual condition with many causes. Two cases are presented in which it appeared to be related to whole pelvis irradiation in one patient for carcinoma of the vagina and in another for carcinoma of the vulva. The diagnosis is made by paracentesis and analysis of the fluid. The underlying disease usually requires identification by exploratory laparotomy. Although a malignant process is the most common cause, the only findings in the authors' cases were widespread radiation changes in the intestine. After diagnosis treatment by low-fat diet with medium-chain triglyceride supplements resulted in disappearance of chylous ascites.

    The decrease of erythrocyte deformability may be one of the predisposing factors for pulmonary hypertension and ascites in broiler chickens. In mammals, the cytoplasmic calcium is a major regulator of erythrocyte deformability. In this study, the erythrocyte deformability was measured, and the precise locations of Ca2+ and Ca2+ -ATPase in the erythrocytes were investigated in chickens with ascites syndrome induced by low ambient temperature. The results showed that ascitic broilers had higher filtration index of erythrocyte compared with control groups, indicating a decrease in erythrocyte deformability in ascitic broilers. The more calcium deposits were observed in the erythrocytes of ascitic broilers compared with those of the age-matched control birds. The Ca2+ -ATPase reactive grains were significantly decreased on the erythrocyte membranes of ascitic broilers. Our data suggest that accumulation of intracellular calcium and inhibition of Ca2+ -ATPase might be important factors for the reduced deformability of the erythrocytes of ascitic broilers.

    Objective: To evaluate the correlation between Cancer Antigen-25 (CA-125) levels with the amount of ascites in patients with liver cirrhosis. Study Design: Observational, analytical study. Place and Duration of Study: Shifa International Hospital, Islamabad, from March 2012 to February 2013. Methodology: A total of 130 patients with liver cirrhosis (with and without ascites) had serum CA-125 levels measured. The amount of ascites was classified according to physical examination and ultrasound (USG) findings. CA-125 levels were compared and correlated with amount of ascites. Results: Majority of patients (57%) had hepatitis C virus and 60% were in class Child Pugh C. There was moderate correlation between amount of ascites and CA-125 levels (r = 0.642, p < 0.001) with significant raised levels of CA-125 in patients with ascites (p < 0.001). Conclusion: There was a moderate correlation between CA-125 levels and presence and amount of ascites. (author)

    In 5-10% of cases ascites is not controlled by medical therapy and is defined refractory. These patients may be submitted to one of the four following surgical options: portal-systemic shunt, peritoneo-venous shunt, transjugular intrahepatic portal-systemic shunt, orthotopic liver transplantation. Although the portal-systemic shunt is efficient in clearing ascites, it does not improve the survival, which depends on liver function, and it is complicated by an important incidence of encephalopathy. Since the patients with refractory ascites and good hepatic risk are not usually many, it is possible to understand why derivative surgery has been disappointing with this indication. Although the peritoneo-venous shunt is associated with a significant rate of valve obstruction, it is an easy, effective and not expensive treatment. So, till now, it has been considered the first choice procedure of refractory ascites, if any situations, determinating the onset of postoperative complications, are not present. Recently a new method has been introduced in the therapy of portal hypertension, the transjugular intrahepatic portal-systemic shunt. This is a bloodless portal-systemic derivation and so it has caused great enthusiasm even if the available data are insufficient to give a definitive opinion on its role in management of ascites. Certainly the liver transplantation, which presents the great advantage to treat both the cirrhosis and its complications, seems to be the most rational therapy for these patients. However, at least for this moment, the well-known absence of organ donors makes still actual the palliative surgical measures. PMID:9489332

  6. Growth rate of ascites-resistant versus ascites-susceptible broilers in commercial and experimental lines.

    The high growth rate (GR) of contemporary broilers is driven by high rate of feed intake and metabolism. Because of the consequent high oxygen demand, especially when coupled with exposure to high altitude or low temperatures, some broilers fail to regulate oxygen supply and develop the ascites syndrome (AS), which leads to mortality and economic losses. Because of the association between high GR, oxygen demand, and AS, it has been suggested that AS is induced by high GR. If true, further GR enhancement should be avoided because it will increase the proportion of AS-susceptible individuals in contemporary stocks. An alternative hypothesis claims that AS is associated with high actual GR only because the latter increases oxygen demand and that there are genetically AS-resistant broilers that do not develop AS, even when exhibiting high GR. These hypotheses were tested in trials in the years 2002 and 2006, with broilers differing in potential GR: contemporary fast-growing commercial lines and an experimental line derived from commercial broilers in 1986, and (in 2002 only) divergently selected AS-susceptible and AS-resistant lines. A protocol of high-challenge ascites-inducing conditions (AIC) from d 19 was used to distinguish between AS-susceptible and AS-resistant individuals and to determine their GR up to this age. The difference in AS incidence between the divergent lines (93.9 vs. 9.5%) was not explained by the 5% difference in their GR, thus indicating a lack of genetic correlation. In the broiler lines, AS incidence was 31 and 47% in 2002 and 2006, respectively, and 32% in the 1986 slow-growing line. Most broilers that remained healthy under the high-challenge AIC exhibited the same early GR and BW as those that later developed AS. These results, and the relatively high incidence of AS in the slow-growing line, indicate that there is very little, if any, direct genetic association between AS and genetic differences in potential GR, and suggest that AS

    The rapid growth of modern broilers is associated with enhanced appetite and high metabolic rate and, consequently, high O(2) demand. Ascites syndrome (AS) develops in individuals that fail to fully supply the increasing demand for O(2) in their bodies under ascites-inducing conditions (AIC) such as high altitude or low temperatures. The tendency of broilers to develop AS is heritable, but efficacious selection against AS susceptibility (without affecting the normal expression of other important traits) requires identification of indirect selection criteria. In the present study, divergent AS-susceptible (AS-S) and AS-resistant (AS-R) lines were developed to confirm the heritability of AS and to facilitate future detection of criteria for indirect selection against AS susceptibility. The base population consisted of 85 sire families with a mean of 73 progeny per sire, reared in a commercial broiler house under low-challenge AIC (cold environment and pelleted feed). Chicks dying with AS manifestations were designated AS-susceptible, whereas the surviving birds were designated AS-resistant. By the end of the trial (d 48), AS mortality had accumulated to 17.2%, but AS incidence per family (%ASF) ranged from 0 to 49%, with a high heritability (0.57). Parents of 7 families with very high %ASF produced the first generation (S(1)) of the AS-S line, and parents of 7 families with very low %ASF produced the S(1) of the AS-R line. The S(1) males and females reproduced generation S(2) of the selected lines, whereas additional S(1) males were tested under high-challenge AIC (individual cages, cool wind, and pelleted feed). Progeny testing under this high-challenge AIC, followed by sib selection, was repeated in generations S(2) and S(3), resulting in a divergence of 86.6% in the incidence of AS between the AS-S (91.3%) and AS-R (4.7%) lines. The rapid genetic divergence, and family analysis of %ASF suggested that a single or few major genes are responsible for the difference

  8. Intervention for pleural effusions and ascites following liver transplantation

    International Nuclear Information System (INIS)

    Background. Small volumes of fluid in the pleural and peritoneal cavities are common after paediatric liver transplantation. Occasionally, larger fluid collections develop and need intervention by aspiration or insertion of a drain. Objective. To assess the incidence of moderate and large pleural and peritoneal fluid collections following paediatric liver transplantation, the need for intervention and the outcome following radiological and non-radiological treatment, with the ultimate objective of recommending a treatment protocol for such post-operative fluid collections. Materials and methods. A total of 184 consecutive liver grafts in 164 children were reviewed. Results. Of 184 grafts, 31 (16.8 %) developed excessive fluid collections requiring intervention (19 pleural effusions, 8 ascites and 4 effusions and ascites). The effusions were first diagnosed between days 1 and 44 after transplant and the ascites between days 1 and 14. The initial diagnosis was made radiologically in 21 (91 %) of 23 pleural effusions and in 10 (83 %) of 12 ascites. No identifiable cause or association was seen in 18 (58 %) of 31 cases. The mean duration of the pleural effusions and ascites, from onset of treatment to resolution, ranged from 33 ± 42 days (SD) to 35 ± 48 days and from 36 ± 47 days to 39 ± 46 days respectively. Comparison of the modes of interventional treatment (i. e. unguided, radiological and surgical) showed no statistically significant difference in the outcome of the management. Conclusions. Post-transplantation pleural effusions and ascites requiring intervention are often without definite cause. They are more common with reduced grafts, but this cannot completely explain the occurrence or the protracted duration of accumulation in spite of combined interventional management. The outcome of treatment is not significantly influenced by the mode of intervention except in cases where surgical intervention is indicated. Patients could be managed effectively

    AIM: To evaluate the role of leptin levels in the differential diagnosis of ascites.METHODS: Ascitic leptin, TNFα and serum leptin levels were measured in 77 patients with ascites (35 with malignancies, 30 cirrhosis and 12 tuberculosis). Control serum samples were obtained from 20 healthy subjects.Leptin and TNFα levels were measured by ELISA. Body mass index (BMI) and percentage of body fat (BFM) by skin fold measurement were calculated for all patients and control groups. Peritoneal biopsy, ascites cytology and cultures or biochemical values were used for the diagnosis of patients.RESULTS: In patients with malignancies, the mean serum and ascites leptin levels and their ratios were significantly decreased compared to the other patient groups and controls. In tuberculosis peritonitis, ascitic fluid TNFα levels were significantly higher than malignant ascites and cirrhotic sterile ascites. BMI and BFM values did not distinguish between patients and controls.CONCLUSION: In patients with malignant ascites,levels of leptin and TNFα were significantly lower than in patients with tuberculous ascites.

    Ascites syndrome is a metabolic disorder in broilers. Mortality due to ascites results in significant economic losses and has a negative impact on animal welfare. It has been shown that genetic factors play a considerable role in susceptibility of birds to ascites, which offers perspectives for selection against this syndrome. The aim of the present study was to evaluate the consequences of alternative selection strategies for BW and resistance to ascites syndrome using deterministic simulation. In addition to the consequences of current selection (i.e., selection for increased BW only) alternative selection strategies including information on different ascites-related traits measured under normal or cold conditions and the consequences of having information on the underlying genes (i.e., MAS) were quantified. Five different breeding schemes were compared based on the selection response for BW, ascites susceptibility, and the rate of inbreeding. Traits investigated in the index as indicators for ascites were hematocrit value (HCT) and ratio of right ventricle to the total ventricular weight of the heart (RV:TV). The results indicated that by ignoring ascites susceptibility in the breeding goal, the gain for BW is 130 g and the birds will become more susceptible to ascites. Testing 50% of the birds under cold temperature conditions and including information of ascites related traits (HCT and RV:TV) measured under normal and cold conditions makes it possible to achieve a relatively high gain for BW (111.4 g) while controlling the genetic level for ascites susceptibility (selection response was 0). The results of scenarios including QTL information of ascites susceptibility showed that QTL information could be used very effectively in controlling ascites susceptibility. PMID:15844807

    Full Text Available Gastrointestinal involvement is frequent in patients with systemic lupus erythematosus (SLE. Eosinophilic gastroenteritis, however, has only rarely been described in rheumatological conditions, despite its reported connection to autoimmune diseases, such as hypereosinophilic syndrome, vasculitides, and systemic mastoidosis. It presents typically with abdominal pain and diarrhea and is only exceptionally associated with ascites. Diagnosis can be problematic, as several other clinical conditions (malignancies, infection/tuberculosis, and inflammatory bowel diseases have to be ruled out. It is basically a nonsurgical disease, with excellent recovery on conservative treatment. We report the rare case of a young woman with overlap syndrome who presented with abdominal pain and ascites. The diagnosis of eosinophilic enteritis was made based on clinical, radiological, and laboratory criteria. The patient was treated with corticosteroids with excellent response.

However, a normal liver stiffness could rule out hepatic causes of ascites at an early stage. The aim of the present study was to determine whether liver stiffness can be generally determined by transient elastography through an ascites layer, to determine whether the ascites-mediated increase in intra-abdominal pressure affects liver stiffness, and to provide initial data from a pilot cohort of patients with various causes of ascites.Methods and results: Using the XL probe in an artificial ascites model, we demonstrated (copolymer phantoms surrounded by water that a transient elastography-generated shear wave allows accurate determination of phantom stiffness up to a water lamella of 20 mm. We next showed in an animal ascites model that increased intra-abdominal pressure does not affect liver stiffness. Liver stiffness was then determined in 24 consecutive patients with ascites due to hepatic (n = 18 or nonhepatic (n = 6 causes. The cause of ascites was eventually clarified using routine clinical, imaging, laboratory, and other tools. Valid (75% or acceptable (25% liver stiffness data could be obtained in 23 patients (95.8% with ascites up to an ascites lamella of 39 mm.

He had a history of untreated hypertension, compensated renal insufficiency and COPD. Despite weight loss and fatigue, the patient did not experience any other constitutional symptoms such as fever, night sweats or loss of appetite. Investigations: Physical examination, blood tests, CT scan of the abdomen, MRI scan of the abdomen, fine needle biopsy, excisional biopsy, Video Capsule Endoscopy, histology, PET scan. Diagnosis: Inflammatory myofibroblastic tumor, chylous ascites, chyloperitoneum. Management: Systemic chemotherapy, total parenteral nutrition and octreotide therapy. Conclusion: We describe the case of a patient in whom two extremely rare phenomena are present in combination: the diagnosis of an inflammatory myofibroblastic tumor and chylous ascites. While the tumor could be stabilized by different regimens of chemotherapy, the chyloperitoneum was treated with parenteral nutrition and subcutaneous octreotide injections, which resulted in a significant reduction of the amount of chylous ascites drained during regular paracentesis.

    Full Text Available Eosinophilic gastroenteritis is a rare gastrointestinal (GI disorder characterized by nonspecific GI symptoms, peripheral eosinophilia, and eosinophilic infiltration of the intestinal wall. The disorder is classified into mucosal, muscular, and sub-serosal types, depending on the clinical picture and the depth of eosinophilic infiltration within the GI wall. Sub-serosal disease, which is complicated by ascites, usually results in the most severe clinical form of eosinophilic gastroenteritis and requires early corticosteroid therapy. In such cases, a favorable outcome can be achieved after a short course of corticosteroids. We present the case of a 28-year-old female with diffuse abdominal pain and distention for 2 weeks. Her physical examination was significant for moderate ascites. Initial work-up demonstrated severe peripheral blood eosinophilia, normal liver function tests, and elevated serum immunoglobulin E (IgE. Upper endoscopy, colonoscopy showed a thickening of the stomach and colon, and biopsies showed marked eosinophilic infiltration of the mucosa. Ascitic fluid analysis showed significant eosinophilia. Subsequent treatment with oral prednisone resulted in the normalization of laboratory and radiologic abnormalities 45 days after the start of the treatment. Despite its rarity, eosinophilic gastroenteritis needs to be recognized by the clinician because the disease is treatable, and timely diagnosis and initiation of treatment could be of major importance.

  18. Role of malignant ascites on human mesothelial cells and their gene expression profiles

    International Nuclear Information System (INIS)

    Malignant ascites is often present at diagnostic in women with advanced ovarian cancer (OC) and its presence is associated with a worse outcome. Human peritoneal mesothelial cells (HPMCs) are key components of malignant ascites. Although the interplay between HPMCs and OC cells is believed to be critical for tumor progression, it has not been well characterized. The purpose of this study was to assess the effect of ascites on HPMCs and clarify the role of HPMCs in OC progression. Human OC ascites and benign peritoneal fluids were assessed for their ability to stimulate HPMC proliferation. Conditioned medium from ascites- and benign fluid-stimulated HPMCs were compared for their ability to attenuate apoptosis induced by TNF-related apoptosis-inducing ligand (TRAIL). We conducted a comparative analysis of global expression changes in ascites-stimulated HPMCs using Agilent oligonucleotide microarrays. As compared to benign peritoneal fluids, malignant ascites stimulated the proliferation of HPMCs. TRAIL-induced apoptosis was attenuated in OC cells exposed to conditioned medium from ascites-stimulated HPMCs as compared to OC cells exposed to conditioned medium from benign fluid-stimulated HPMCs. A total of 649 genes were differentially expressed in ascites-stimulated HPMCs. Based on a ratio of more than 1.5-fold and a P < 0.05, 484 genes were up-regulated and 165 genes were down-regulated in ascites-exposed HPMCs. Stimulation of HPMCs with OC ascites resulted in differential expression of genes mainly associated with the regulation of cell growth and proliferation, cell death, cell cycle and cell assembly and organization, compared to benign peritoneal fluids. Top networks up-regulated by OC ascites included Akt and NF-κB survival pathways whereas vascular endothelial growth factor (VEGF) pathway was down-regulated. The results of this study not only provide evidence supporting the importance of the interplay between cancer cells and HPMCs but also define the role

    Ascites syndrome is a metabolic disorder found in modern broilers that have insufficient pulmonary vascular capacity. Commercial breeding programs have heavily focused on high growth rate, which led to fast-growing chickens, but as a negative consequence, the incidence of ascites syndrome increased. However, not all birds with a high growth rate will suffer from ascites syndrome, which might indicate a genetic susceptibility to ascites. Information on blood gas parameters measured early in life and their relation to ascites susceptibility is expected to contribute to identification on the cause of ascites syndrome. In this study, several physiological parameters, such as blood gas parameters [pH, partial pressure of CO(2) in venous blood (pvCO(2)), and partial pressure of O(2) in venous blood], hematocrit, electrolytes (Na(+), Ca(2+), and K(+)), metabolites (lactate and glucose), were measured at d 11 to 12 of age from 100 female and 100 male broilers. From d 14 onward, the birds were challenged to provoke the development of ascites syndrome. Our results showed that high pvCO(2) values together with low pH values (males) or high pH values (females) in the venous blood of juvenile broilers coincided with ascites. Therefore, blood pvCO(2) and pH in both juvenile male and female broilers seem to be critical factors in ascites pathophysiology and can be used as phenotypic traits to predict ascites susceptibility in juvenile broilers at d 11 to 12. A prediction model was built on a subpopulation of the broilers without any loss in sensitivity (0.52) and specificity (0.78) when applied to the validation population. The parameter sex was included in the prediction model because levels of pvCO(2) and pH that associated with ascites susceptibility are different between males and females. Commercial breeders can include these phenotypic traits in their genetic selection programs to reduce the incidence of ascites syndrome. PMID:20634524

    This study reports novel insight into the aetiology of pulmonary hypertension and ascites in broiler chickens. The scope of measurements was focused on anatomical and functional parameters, and blood flow patterns in leghorns (resistant to ascites), fast-growing broilers (susceptible to ascites), broilers developing ascites, and ascitic broilers evaluated in vivo using echocardiography, and further examined in the context of postmortem findings. Both, in vivo observed features and postmortem findings, showed clear differences between broilers and leghorns, and between normal and ascitic broilers. Abnormalities in the heart chamber geometry and blood flow patterns were detected upon echocardiographic examination in all ascitic broilers. Right and left atrio-ventricular (AV) valve regurgitation were common findings in ascitic broilers and some apparently normal broilers, with left AV valve insufficiency being a predominant feature with respect to degree and frequency of occurrence. Blood flow disturbances were not detected in leghorns. Left ventricular fractional shortening (functional parameter) was considerably reduced (P ascitic birds (mean: 21.7 +/- 2.0 SE) in comparison with normal broilers (mean: 39.1 +/- 3.6 SE), or leghorns (mean: 43.3 +/- 2.4 SE). The presented findings indicate that pathological and functional changes in the left ventricle and atrium play a significant role in the pathogenesis of ascites in broilers. Severe dilation of the left atrium and pulmonary veins seen on postmortem examination, as well as regurgitant blood flow in the left atrium, demonstrated by Doppler study in ascitic birds, provide evidence that chronically elevated pressure in the left atrium is involved in the aetiology of pulmonary hypertension and ascites in fast-growing broilers.

    Ascites syndrome is still a problem for chicken industry in various parts of the world. Despite the intensive investigations of this syndrome for many years, its pathogenesis remains unclear. The objective of this study was to analyze the difference in hepatic proteomics between ascites and healthy broilers by two-dimensional electrophoresis (2-DE) and matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF-MS). Changes of biochemical parameters of liver and blood were also determined. The results indicated that red blood cell counts (RBC), hematocrit (HCT) and haemoglobin (HGB) of ascites broilers were significantly greater than healthy broilers. Hepatic malondialdehyde (MDA) level of ascites broilers was significantly increased, and the activity of total superoxide dismutase (T-SOD) was significantly decreased. Hepatic lactic acid (LD) level of ascitic broilers were significantly lower than healthy ones. Serum glucose and cholesterol level of ascites broilers were significantly increased, and serum globulin level was significantly decreased in ascites broilers. There was no significant difference in triglyceride (TG) and blood urea nitrogen (BUN) level. The activity of liver hexokinase (HK) and succinodehydrogenase (SDH) in ascites broilers was significantly decreased, and there was no significant difference in the activity of liver pyruvate kinase (PK) and Na+-K+-ATPase. The hepatic proteomics analysis showed that 18 proteins expression difference were identified between ascites and healthy broilers. These proteins were mainly involved in: 1) cytoskeleton; 2) glucose, lipids and amino acid metabolism; 3) cell secretion; 4) cell apoptosis; 5) signal transduction; 6) immune and inflammatory response; and 7) cellular redox homeostasis. Mitochondrial isoform phosphoenolpyruvate carboxykinase (M-PEPCK) mainly participates in gluconeogenesis of chicken liver. In conclusion, liver oxidative damage was significantly aggravated, but

    Postoperative chylous ascites is a rare complication of retroperitoneal surgery. The treatment of postoperative chylous ascites is primarily conservative, consisting of repeated paraceteses, medium chain triglyceride (MCT) diet, salt restriction, diuretics and bowel rest with total parenteral nutrition. Occasionally, chylous ascites may take a protracted course which may necessitate insertion of peritoneo-venous shunts or direct surgical lymphostasis. Recently, Somatostatin was shown to be highly effective in closure of refractory lymphatic fistulas. We present a case of refractory chylous ascites following radical nephrectomy with inferior vena caval thrombectomy that failed to respond to conventional conservative measures and resolved rapidly following the administration of Somatostatin.

    The effects of graded atmospheric O2 concentration (12, 14, 16, 18, and 20.6%) on chick performance and propensity to develop ascites were investigated using commercial male broilers. Chicks were housed in calorimetry chambers for 2 wk with incoming air diluted with N to provide the desired O2 concentration at thermoneutral (TN) ambient temperature. Day 14 body weight, weight gain, feed consumption, and gain-to-feed ratio increased (P Ascites heart ratio (AHR), ascites score (AS), right ventricular mass (RVM), and hematocrit (HCT) all increased (P ascites.

    Genetic selection based on rapid growth rates, improved feed conversion, and increased body weights has led to a predisposition to ascites in broiler populations. Sire-family selection was applied to a commercial elite line to produce divergent lines of ascites-resistant (RES) and ascites-susceptible (SUS) broilers by the 8th generation. One objective of this research was to determine the effects of hypobaric hypoxia on gut morphology in these genetic lines. In two separate trials, pedigree broiler chickens were randomly assigned to cages in a hypobaric chamber (simulated 2,900 m above sea level) or a matching local altitude chamber (390 m above sea level). Ascites incidence was characterized by heart enlargement and fluid accumulation in the abdominal cavity. At the end of the study on d 42, all surviving birds were killed and evaluated for the presence of ascites and 2-cm sections from the duodenum and lower ileum were collected from 5 chickens per line, per altitude for each trial for morphometric analysis. At a high altitude, ascites incidence was lower in the RES line (20.9 and 3.7%) than in the SUS line (86.4 and 66.9%, Trials 1 and 2, respectively). No ascites was observed at a local altitude. Under hypoxic conditions, duodenum villus surface area was higher (P ascites susceptibility suggests reduced enteric function and may provide clues as to why these birds have increased incidence of ascites.

    (1) Pulmonary hypertension syndrome followed by ascites is a metabolic disorder in broilers that occurs more often in fast-growing birds and at cool temperatures. (2) Knowledge of the genetic relationships among ascites-related traits and performance traits like carcase traits or feed efficiency traits is required to design breeding programmes that aim to improve the degree of resistance to ascites syndrome as well as production traits. The objective of this study was to estimate these genetic correlations. (3) Three different experiments were set up to measure ascites-related traits (4202 birds), feed efficiency traits (2166 birds) and carcase traits (2036 birds). The birds in different experiments originated from the same group of parents, which enabled the estimation of genetic correlations among different traits. (4) The genetic correlation of body weight (BW) measured under normal conditions and in the carcase experiment with the ascites indicator trait of right ventricle to total ventricle ratio (RV:TV) measured under cold conditions was 0.30. The estimated genetic correlation indicated that single-trait selecting for BW leads to an increase in occurrence of the ascites syndrome but that there are realistic opportunities of multi-trait selection of birds for improved BW and resistance to ascites. (5) Weak but positive genetic relationships were found between feed efficiency and ascites-related traits suggesting that more efficient birds tend to be slightly more susceptible to ascites. (6) The relatively low genetic correlation between BW measured in the carcase or in the feed efficiency experiments and BW measured in the ascites experiment (0.49) showed considerable genotype by environment interaction. (7) These results indicate that birds with high genetic potential for growth rate under normal temperature conditions have lower growth rate under cold-stress conditions due to ascites.

    Laparoscopic living donor nephrectomy (LLDN) is a minimally invasive technique for kidney procurement and was developed with the hope of reducing the disincentives associated with live renal donation. Compared with open donor nephrectomy (ODN), this alternative has many advantages including less postoperative pain and earlier return to work. Unfortunately, these benefits are sometimes negated by postoperative complications. Among these, chylous ascites (CA) is a rare but serious problem that is usually managed conservatively. We report the case of a living donor who developed CA refractory to initial conservative management and surgical treatment. We also discuss the role of surgery in the treatment of CA following LLDN.

    Full Text Available Protein tyrosine phosphatases (PTPases regulate tyrosine phosphorylation of target proteins involved in several aspects of cellular functions. Enzyme activities of the PTPases in cytosolic and particulate fractions of rat ascites hepatoma cell lines were determined and compared with those of normal rat liver. Our present data revealed that although there was no neoplatic-specific alteration of the PTPase activity in examined hepatomas, the activity in particulate fractions of island type of hepatomas was remarkably decreased compared with either rat liver or free type hepatomas.

  13. Pulmonary arterial hypertension (ascites syndrome) in broilers: a review.

    2013-01-01

    Pulmonary arterial hypertension (PAH) syndrome in broilers (also known as ascites syndrome and pulmonary hypertension syndrome) can be attributed to imbalances between cardiac output and the anatomical capacity of the pulmonary vasculature to accommodate ever-increasing rates of blood flow, as well as to an inappropriately elevated tone (degree of constriction) maintained by the pulmonary arterioles. Comparisons of PAH-susceptible and PAH-resistant broilers do not consistently reveal differences in cardiac output, but PAH-susceptible broilers consistently have higher pulmonary arterial pressures and pulmonary vascular resistances compared with PAH-resistant broilers. Efforts clarify the causes of excessive pulmonary vascular resistance have focused on evaluating the roles of chemical mediators of vasoconstriction and vasodilation, as well as on pathological (structural) changes occurring within the pulmonary arterioles (e.g., vascular remodeling and pathology) during the pathogenesis of PAH. The objectives of this review are to (1) summarize the pathophysiological progression initiated by the onset of pulmonary hypertension and culminating in terminal ascites; (2) review recent information regarding the factors contributing to excessively elevated resistance to blood flow through the lungs; (3) assess the role of the immune system during the pathogenesis of PAH; and (4) present new insights into the genetic basis of PAH. The cumulative evidence attributes the elevated pulmonary vascular resistance in PAH-susceptible broilers to an anatomically inadequate pulmonary vascular capacity, to excessive vascular tone reflecting the dominance of pulmonary vasoconstrictors over vasodilators, and to vascular pathology elicited by excessive hemodynamic stress. Emerging evidence also demonstrates that the pathogenesis of PAH includes characteristics of an inflammatory/autoimmune disease involving multifactorial genetic, environmental, and immune system components.

    AIM: To examine the paclitaxel concentrations in plasma and ascites after its intravenous administration in patients with ascites due to peritonitis carcinomatosa resulting from advanced gastric cancer.METHODS: Two patients with ascites due to peritonitis carcinomatosa resulting from gastric cancer were included in this study. The paclitaxel concentrations in plasma and ascites were investigated for 72 h in case 1 and 168 h in case 2 after intravenous administration.RESULTS: The paclitaxel concentration in plasma peaked immediately after administration, followed by rapid decrease below the threshold value of 0.1 μmol (85 ng/mL) within 24 h. In contrast, the paclitaxel concentration in ascites increased gradually for 24 h after administration to a level consistent with the level found in plasma. After 24 h the level of paclitaxel in ascites and plasma became similar, with the optimal level being maintained up to 72 h following administration.CONCLUSION: The concentration of paclitaxel in ascites is maintained within the optimal level for the treatment of cancer cells for up to 72 h after intravenous administration. Paclitaxel is a promising drug for the treatment of malignant ascites of gastric cancer.

    Pancreatic ascites or internal pancreatic fistula is a known complication of chronic pancreatitis. This condition is associated with considerable morbidity and mortality. The management approach of pancreatic ascites in tropical calcific pancreatitis is infrequently reported owing to the low incidence of this condition. Between December 2005 and June 2007, 11 patients with pancreatic ascites with tropical calcific pancreatitis (male:female 7:4, mean age 29.5 [14.2] years) were treated. A retrospective analysis of patients who underwent endotherapy and surgery for this condition based on an institutional protocol was performed. The end point was resolution of pancreatic ascites and relief of symptoms. All patients had pancreatic ascites, and one patient also had pancreatic pleural effusion. Endoscopic transpapillary stenting was possible in nine patients (81%). Identification of site of leak and placement of an endoscopic stent across the PD disruption was possible in five (45%) patients. All these patients had relief of ascites. Mean number of endotherapy sessions required before control of ascites was 1.8. Among the remaining four (36.6%) patients who had ERCP, placement of stent across the leak was unsuccessful; however stenting helped stabilize the general condition and nutritional status. These four patients and two patients who failed ERP underwent lateral pancreatojejunostomy surgery. Morbidity was observed in three patients who underwent surgery and one patient died due to sepsis and hemorrhage. All patients who had surgical drainage had complete relief of ascites and symptoms. In patients with pancreatic ascites in tropical calcific pancreatitis endotherapy and transpapillary stenting helps in resolution of ascites in nearly half of the patients. In the remaining patients preliminary conservative management followed by surgical pancreatic ductal drainage provides good relief of symptoms. PMID:19907961

    Vitamin B12 deficiency is widespread than assumed in population. At risk are older people, pregnant women, vegans, patients with renal and intestinal diseases. Vitamin B12 deficiency can present with various hematological, gastrointestinal and neurological manifestations. In the population, the prevalence of vitamin B12 deficiency in younger people is 5% to 7% which is less compared to elderly people. In developing countries, deficiency is much more common, starting in early life and persisting across the life span. Here, we present a 16-year-old female patient presenting with ascites since 2 months who was subsequently investigated and diagnosed to have nutritional megaloblastic anaemia secondary to vitamin B12 deficiency after exclusion of other infective, neoplastic, autoimmune and inflammatory diseases. Inspite, patient was treated with antitubercular drugs but she did not respond. After supplementation of Vitamin B12, ascites responded well. Inadequate intake due to low consumption of animal source foods is the main cause of low serum vitamin B12 in younger adults and likely the main cause in poor population worldwide. PMID:25177593

    Full Text Available Abstract Background The purpose of this study was to determine risk factors for development of malignant ascites and its prognostic significance in patients with pancreatic cancer. Methods A prospective database was queried to identify patients with pancreatic cancer who develop ascites. Stage at presentation, size, and location of primary tumor, treatment received and length of survival after onset of ascites were determined. Results A total of 15 patients were identified. Of which 4 patients (1 stage II, 3 stage III underwent pancreaticoduodenectomy and manifested with ascites 2, 3, 24 and 47 months after surgery (tumor size 2.9 ± 1.32 cm. All but one of the remaining 11 patients (tumor size 4.4 ± 3.38 cm presented with metastatic disease, and all developed malignant ascites 9 months after diagnosis, dying 2 months later. Resected patients lived longer before the onset of ascites, but not after. Conclusion Once diagnosed, ascites in pancreatic cancer patients heralds imminent death. Limited survival should be considered when determining the aggressiveness of further intervention.

    Full Text Available A 65-year-old man with chronic hepatitis C and no history of alcohol abuse was admitted to our liver unit for the recent development of massive ascites and presumed hepatorenal syndrome. In the preceding two weeks, he had received medical treatment for acute pancreatitis and cholecystitis. Abdominal paracentesis demonstrated a cloudy, orange peritoneal fluid, with total protein concentration 3.6 g/dl, serum-ascites albumin gradient 1.0 g/dl, and ratios of ascites-serum bilirubin and amylase approximately 8:1. Diagnostic imaging demonstrated no pancreatic pseudocysts. Ten days later, at laparotomy, acalculous perforation of the gallbladder was identified. After cholecystectomy, amylase concentration in the ascitic fluid dropped within a few days to 40% of serum values; ascites disappeared within a few weeks. We conclude that in the presence of a perforated gallbladder, pancreatobiliary reflux was responsible for this unusual combination of choleperitoneum and pancreatic ascites, which we propose to call pancreatobiliary ascites.

    Modern broilers have been genetically selected for an increased growth rate and improved feed conversion, but they are also more susceptible to ascites. Ascites occurs when there is an imbalance between available oxygen and the oxygen demand of the broiler. We hypothesized that promoting neonatal gut development with a prebiotic, such as Aspergillus meal (Prebiotic-AM), would enhance gut efficiency, decrease the oxygen demand of the gut, and reduce ascites incidence. In this study, we compared the effect of Prebiotic-AM on ascites incidence and gut development in commercial broilers reared at a local altitude (390 m above sea level) and a simulated high altitude (2,900 m above sea level). Half of the birds received a National Research Council recommended corn-soybean ration, and the other half received the same ration supplemented with 0.2% Prebiotic-AM. These 2 groups were further divided into a local altitude group and a simulated high altitude group for a total of 4 treatment combinations. Tissues were collected on d 1, 3, 7, 14, and 21 from the duodenum and lower ileum and placed in 10% buffered formalin for morphometric analysis. At a simulated high altitude, ascites incidence was 68% for birds fed the Prebiotic-AM supplement compared with 92% ascites incidence in birds given the control feed. The simulated high altitude decreased (P broiler gut development and ascites incidence. PMID:16050126

    This study examined the putative role of blood vessel pathology in the development of ascites in broilers. Major blood vessels (aorta, brachiocephalic arteries, pulmonary arteries, and vena cava) from normal commercial male broiler chickens, and broilers that developed congestive heart failure (CHF) with or without ascites were subjected to gross and microscopic examination. On cross-section, grossly, the arteries from normal broilers and those showing dilated cardiomyopathy without ascites appeared circular, with firm wall tone characteristic of the normal artery. In contrast, the arteries from ascitic broilers appeared flaccid and lacked elasticity, which was evidenced by collapsing, ellipsoid cross-sectional arterial lumen owing to the structural weakness of the arterial walls. Microscopically, ascitic broilers showed thinning or occasionally total loss of elastic elements in the arterial wall, and reduced network density of the structural matrix of the vascular wall, as well as increased thickness of fibers in vena cava. The structural changes seen in the major arteries from ascitic broilers are maladaptive, and as such would definitively impose an increased hemodynamic burden on the already failing heart pump. The changes in veins are indicative of pathological remodeling conducive to increased permeability of the vascular wall, particularly in the situation when a poorly distensible structure is further subjected to wall stress associated with increased pressure and volume overload. Taken together, increased hemodynamic burden and reduced structural density of the venous wall constitute conditions conducive for seepage and accumulation of ascitic fluid. PMID:18947843

    AIM: To study the clinical significance of minimal ascites,which was only defined by the CT and whose nature was not determined preoperatively, in the relationship with the peritoneal carcinomatosis.METHODS: The medical records and the dynamic CT films of 118 patients with gastric cancer were reviewed.Factors associated with peritoneal carcinomatosis were analyzed in 40 patients who had CT-defined ascites of which the nature was surgically confirmed.RESULTS: Only 12.5-25% of the CT-defined minimal ascites, whose volume was estimated to be less than 50 mL, were associated with peritoneal carcinomatosis.When the estimated CT-defined ascitic volume was 50 mL or more, peritoneal carcinomatosis was identified in 75-100%. When CT-defined lymph node enlargements were not found beyond the regional gastric area,perigastricinvasions were not suspected, and the size of tumor was less than 3 cm, peritoneal carcinomatosis seemed significantly less accompanied at the univariate analysis. However, except for the minimal volume of CTdefined ascites in comparison with the mild or more,other factors were not confirmed multivariately.CONCLUSION: In the patients with gastric cancer, CTdefined minimal ascites alone is rarely associated with peritoneal carcinomatosis, if it does not accompany other signs suggestive of malignant seeding. Therefore,consideration of active curative resection should not be hesitated, if CT-defined minimal ascites is the only delusive sign.

    1. The mean incidence of deaths from ascites in the UK in 1993 was 1.4% (0.7% in 1991 and 0.9% in 1992) and 0.8% from sudden death syndrome (SDS). In total, the economic loss to the UK Broiler Industry in 1993 as a result of these 2 conditions was 24 Pounds M. 2. Clear geographical differences emerged in the occurrence of ascites, with, not only the lowest incidences being observed in Northern Ireland, but also the peak of the mortality from ascites occurring much later in the rearing cycle than in other regions on the mainland. 3. In all regions the incidence of SDS was lower than that of ascites but the reason for this disparity remains to be established. 4. Some of the variables associated with the road transportation of day-old chicks from the hatchery to the farm appeared to influence the incidence of ascites. These included distance or time travelled, stocking density, internal lorry temperature and the length of time the lorry was heated before transport as well as the time the shed was heated before chick arrival. Temperature was also an important factor during growth (brooding and finishing). 5. Negative pressure-powered ventilation was preferred in most organisations but more ascites was seen with positive pressure ventilation. However, the lowest incidence of ascites occurred with natural ventilation. There was more ascites relative to shed orientation when the wind direction was from the west compared to the east. 6. This survey identifies the extent of the problem of broiler ascites in the UK and also highlights the importance of good management control of day-old chicks, not only following placement, but even before their arrival on the farm.

    Full Text Available Abstract Background The acellular fraction of epithelial ovarian cancer (EOC ascites promotes de novo resistance of tumor cells and thus supports the idea that tumor cells may survive in the surrounding protective microenvironment contributing to disease recurrence. Levels of the pro-inflammatory cytokines IL-6 and IL-8 are elevated in EOC ascites suggesting that they could play a role in tumor progression. Methods We measured IL-6 and IL-8 levels in the ascites of 39 patients with newly diagnosed EOC. Commercially available enzyme-linked immunosorbent assay (ELISA was used to determine IL-6 and IL-8 ascites levels. Ascites cytokine levels were correlated with clinicopathological parameters and progression-free survival. Results Mean ascites levels for IL-6 and IL-8 were 6419 pg/ml (SEM: 1409 pg/ml and 1408 pg/ml (SEM: 437 pg/ml respectively. The levels of IL-6 and IL-8 in ascites were significantly lower in patients that have received prior chemotherapy before the surgery (Mann-Whitney U test, P = 0.037 for IL-6 and P = 0.008 for IL-8. Univariate analysis revealed that high IL-6 ascites levels (P = 0.021, serum CA125 levels (P = 0.04 and stage IV (P = 0.009 were significantly correlated with shorter progression-free survival. Including these variables in a multivariate analysis revealed that elevated IL-6 levels (P = 0.033 was an independent predictor of shorter progression-free survival. Conclusion Elevated IL-6, but not IL-8, ascites level is an independent predictor of shorter progression-free survival.

  7. Effect of administration of some antitumor extracts on Ehrlich ascites carcinoma-bearing mice

    International Nuclear Information System (INIS)

    Cancer is considered one of the most common causes of morbidity and mortality worldwide. Many researches have been studied on the discovery of natural and synthetic compounds that can be used in the prevention and/or treatment of cancer. Many chemo preventive agents have been associated with antiproliferative and apoptotic effects on cancer cells because of their high antioxidant activity. The present study was undertaken to investigate the antioxidant and antitumor effects of three natural extracts including (propolis, green tea and Chlorella vulgaris) without or with radiation exposure in Ehrlich ascites carcinoma (EAC) - bearing female albino mice. The animals were randomly distributed into three major groups as follows:- Group A (control group).This group consists of 10 mice kept on normal standard rodent diet without any treatment and housed in two cages: mice of the first cage served as control for non tumor-bearing group and the second cage served as control for tumor-bearing group. Group B (Non tumor - bearing group).This group consists of 30 mice and used to study the effect of the vehicle solutions (gum acacia, DMSO), propolis, green tea, Chlorella vulgaris and gamma irradiation on normal mice. Mice of this group were equally distributed into six subgroups receiving gum acacia, DMSO, propolis, green tea and Chlorella vulgaris for two weeks and whole body gamma irradiated. Group C (Tumor- bearing group): This group consists of 160 mice randomly and equally distributed into 8 subgroups: Ehrlich ascites carcinoma(mice were inoculated with 2.5 x 106 intra-peretoneally(i.p), Ehrlich ascites carcinoma and 2 Gy irradiated, Ehrlich ascites carcinoma and propolis treated (150 mg/kg b.w), Ehrlich ascites carcinoma, propolis treated and irradiated, Ehrlich ascites carcinoma and green tea treated (150 mg/kg b.w), Ehrlich ascites carcinoma, green tea treated and irradiated, Ehrlich ascites carcinoma and Chlorella vulgaris treated (150 mg/kg b.w) and Ehrlich ascites

    Full Text Available Identification of pathogenic bacteria in ascites correlates with poor clinical outcomes. Ascites samples are commonly reported culture-negative, even where frank infection is indicated. Culture-independent methods have previously reported bacterial DNA in ascites, however, whether this represents viable bacterial populations has not been determined. We report the first application of 16S rRNA gene pyrosequencing and quantitative PCR in conjunction with propidium monoazide sample treatment to characterise the viable bacterial composition of ascites. Twenty five cirrhotic patients undergoing paracentesis provided ascites. Samples were treated with propidium monoazide to exclude non-viable bacterial DNA. Total bacterial load was quantified by 16S rRNA Q-PCR with species identity and relative abundance determined by 16S rRNA gene pyrosequencing. Correlation of molecular microbiology data with clinical measures and diagnostic microbiology was performed. Viable bacterial signal was obtained in 84% of ascites samples, both by Q-PCR and pyrosequencing. Approximately 190,000 ribosomal pyrosequences were obtained, representing 236 species, including both gut and non gut-associated species. Substantial variation in the species detected was observed between patients. Statistically significant relationships were identified between the bacterial community similarity and clinical measures, including ascitic polymorphonuclear leukocyte count and Child-Pugh class. Viable bacteria are present in the ascites of a majority of patients with cirrhosis including those with no clinical signs of infection. Microbiota composition significantly correlates with clinical measures. Entry of bacteria into ascites is unlikely to be limited to translocation from the gut, raising fundamental questions about the processes that underlie the development of spontaneous bacterial peritonitis.

    Genetic selection for an ascites-resistant line of broilers is seen as a permanent solution to the ascites problem. Ascites-resistant and ascites-susceptible lines have been developed using sire family selection based on mortality data taken from siblings reared in a hypobaric chamber (simulated 2,900 m above sea level). The relaxed line is representative of the original commercial pureline stock randomly mated with no artificial selection pressure. The objectives of this study were to evaluate the differences between the lines when reared in floor pens and subjected to an ascites-inducing cold stress. Seven hundred eighty three straight run broilers were reared in floor pens at local elevation (390 m above sea level). Feed and water were available ad libitum. Birds were brooded at 32 C during the first week. The second week birds were maintained at 30 degrees C. Cold stress was applied for the remaining 4 wk at 14 degrees C. Mortalities were necropsied daily to determine cause of death. Birds and feed were weighed weekly. At 6 wk, five birds per pen were bled, and half the survivors in each pen (8 to 15 birds) were killed, necropsied, and scored for ascites. Blood gases, clinical chemistries, and blood cell counts were taken. Liver, spleen, split heart, and lung weights were recorded. Body weights were not different among the resistant, susceptible, and relaxed lines (P Ascites incidence, as measured by mortality and lesion score at necropsy, was higher in the susceptible and relaxed lines when compared to the resistant line; 18.8, 12.7, and 1.6% respectively (P ascites-resistant line was growing as rapidly as the other lines and was as resistant to ascites as it had been under hypobaric conditions.

    AIM: To evaluate the diagnostic value of assaying telomerase activity in ascites cells for the differential diagnosis of malignant and non-malignant ascites.METHODS: Ascites from 40 patients with hepatocellular carcinoma (HCC), 31 with non-HCC gastrointestinal carcinoma (CA), and 24 with liver cirrhosis (LC) were analyzed for telomerase activity. The telomerase activities in cell pellets from ascites were measured according to the Telomeric Repeat Amplification Protocol (TRAP) and quantified with a densitometer.RESULTS: Positive telomerase activity was detected in 16 of 31 (52%) CA patients, 10 of 40 (25%) HCC patients, and 1 of 24 (4%) LC patients (P<0.001). The telomerase activity was higher in the ascites of CA patients than in the ascites of HCC or LC patients (CA: 22.9±5.8, HCC: 6.7±2.5, LC:1.3±1.3, P= 0.001). Cytology was positive in 18 CA patients (58%) and 1 HCC patient (2.5%), respectively. The positive telomerase activity was not related to patients' age, gender,and ascitic protein concentration, but to white blood count (r= 0.31, P= 0.002), neutrophil count (r= 0.29, P= 0.005),and the C-reactive protein level (r= 0.29, P= 0.018). When the results of both cytological examination and telomerase assay were considered together, the sensitivity increased to 77% for CA patients, 25% for HCC patients, and 48% for all 71 gastrointestinal cancer patients.CONCLUSION: Combining cytological examination of ascites with telomerase activity assay significantly improves the differential diagnosis between malignant and non-malignant ascites.

    Full Text Available Abstract Cystic mesotheloma is an uncommon lesion of the peritoneum occurring predominantly in women of reproductive age. The case was a 21 years girl presented with 4 years history of mild abdominal distension and periodic pain. The results of the clinical examinations were normal. Sonography and CT scan confirmed gross ascites. The results of paraclinical tests were normal without any positive findings for etiology of ascites. During laparoscopy multiple transparent cysts were found in pelvic and culdesac. All cysts were removed by laparoscopy. Histology confirmed benign cystic mesotheloma. Reviewing the records revealved that this case is the second case of mesothelial cysts that presented with ascites.

    Persistent cloaca (PC) is a rare abnormality characterized by a direct communication between the gastrointestinal, urinary and genital structures. We report a case of PC presenting with persistent massive fetal ascites. Postpartum examination demonstrated a long and narrow common channel of PC. Fetal ascites is caused by urinary drainage through the fallopian tubes into the abdominal cavity. Usually it occurs temporarily and disappears with the subsequent development of intrapelvic cysts. A long and narrow common channel of PC has been found to contribute to the persistent ascites. PMID:19325242

    Full Text Available Abstract Ascites syndrome is still a problem for chicken industry in various parts of the world. Despite the intensive investigations of this syndrome for many years, its pathogenesis remains unclear. The objective of this study was to analyze the difference in hepatic proteomics between ascites and healthy broilers by two-dimensional electrophoresis (2-DE and matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF-MS. Changes of biochemical parameters of liver and blood were also determined. The results indicated that red blood cell counts (RBC, hematocrit (HCT and haemoglobin (HGB of ascites broilers were significantly greater than healthy broilers. Hepatic malondialdehyde (MDA level of ascites broilers was significantly increased, and the activity of total superoxide dismutase (T-SOD was significantly decreased. Hepatic lactic acid (LD level of ascitic broilers were significantly lower than healthy ones. Serum glucose and cholesterol level of ascites broilers were significantly increased, and serum globulin level was significantly decreased in ascites broilers. There was no significant difference in triglyceride (TG and blood urea nitrogen (BUN level. The activity of liver hexokinase (HK and succinodehydrogenase (SDH in ascites broilers was significantly decreased, and there was no significant difference in the activity of liver pyruvate kinase (PK and Na+-K+-ATPase. The hepatic proteomics analysis showed that 18 proteins expression difference were identified between ascites and healthy broilers. These proteins were mainly involved in: 1 cytoskeleton; 2 glucose, lipids and amino acid metabolism; 3 cell secretion; 4 cell apoptosis; 5 signal transduction; 6 immune and inflammatory response; and 7 cellular redox homeostasis. Mitochondrial isoform phosphoenolpyruvate carboxykinase (M-PEPCK mainly participates in gluconeogenesis of chicken liver. In conclusion, liver oxidative damage was significantly aggravated

    Leveen and associates described a peritoneo-venous shunt which proved to be useful in patients with intractable ascites. Medical therapy, paracentesis and peritoneovenous shunt have been compared, but there is uncertainty about their relative merits. Therefore, the leveen device has be placed in last years in an increasing number of patients: it has not been shown by prospective trials to prolong survival significantly, although it may shorten hospitalization and improve the quality of life. A number of early and late complications were described but they do not influence the general results: origin and features of such complications are discussed as well as their prevention and treatment and personal cases are presented. Selection of patients and careful surgical procedure seems to be mandatory for better results. PMID:8706187

    Ehrlich ascites-tumour cells were investigated with regard to their stability to transport L-lactate by measuring either the distribution of [14C]lactate or concomitant H+ ion movements. The movement of lactate was dependent on the pH difference across the cell membrane and was electroneutral, as evidenced by an observed 1:1 antiport for OH- ions or 1:1 symport with H+ ions. 2. Kinetic experiments showed that lactate transport was saturable, with an apparent Km of approx. 4.68 mM and a Vmax. as high as 680 nmol/min per mg of protein at pH 6.2 and 37 degrees C. 3. Lactate transport exhibited a high temperature dependence (activation energy = 139 kJ/mol). 4. Lactate transport was inhibited competitively by (a) a variety of other substituted monocarboxylic acids (e.g. pyruvate, Ki = 6.3 mM), which were themselves transported, (b) the non-transportable analogues alpha-cyano-4-hydroxycinnamate (Ki = 0.5 mM), alpha-cyano-3-hydroxycinnamate (Ki = 2mM) and DL-p-hydroxyphenyl-lactate (Ki = 3.6 mM) and (c) the thiol-group reagent mersalyl (Ki = 125 muM). 5. Transport of simple monocarboxylic acids, including acetate and propionate, was insensitive to these inhibitors; they presumably cross the membrane by means of a different mechanism. 6. Experiments using saturating amounts of mersalyl as an "inhibitor stop" allowed measurements of the initial rates of net influx and of net efflux of [14C]lactate. Influx and efflux of lactate were judged to be symmetrical reactions in that they exhibited similar concentration dependence. 7. It is concluded that lactate transport in Ehrlich ascites-tumour cells is mediated by a carrier capable of transporting a number of other substituted monocarboxylic acids, but not unsubstituted short-chain aliphatic acids.

    A young pregnant Zambian woman was referred from a district hospital in South Zambia to the university teaching hospital, Lusaka with severe anaemia and ascites. The ascites had developed over a month and the woman was currently 15 weeks pregnant. Further workup revealed that the patient was HIV-positive and the ascitic tap showed haemorrhagic fluid. After being reviewed by multiple doctors, the cause of the haemorrhagic ascites remained unclear; therefore, the decision was made to do a laparotomy. The laparotomy revealed haemoperitoneum and a large cyst attached to the liver containing 5 L of bloodstained fluid. The histopathology report revealed features consistent with a giant haemangioma. There were many barriers to accessing optimum healthcare in this case. These included limited access to blood, poor communication resulting in the patient being unaware of her HIV status and lack of patient education about HIV. PMID:27473033

  20. Percutaneous Placement of Peritoneal Port-Catheter in Patients with Malignant Ascites

    International Nuclear Information System (INIS)

    We report our experience with a radiologically placed peritoneal port-catheter in palliation of malignant ascites. Port-catheters were successfully placed under ultrasonographic and fluoroscopic guidance in seven patients (five women, two men) who had symptomatic malignant ascites. The long-term primary patency rate was 100%. The mean duration of catheter function was 148 days. Seven patients had a total of 1040 port-days. Two patients received intraperitoneal chemotherapy via the port-catheter. There were no procedure-related mortality and major complications. Minor complications such as ascitic fluid leakage from the peritoneal entry site, migration of the catheter tip to the right upper quadrant, and reversal of the port reservoir occurred in four patients. None of these complications affected the drainage and required port explantation. In patients with symptomatic malignant ascites, a peritoneal port-catheter can provide palliation and eliminate multiple hospital visits for repeated paracentesis with high patency and low complication rates

    Full Text Available Purpose: To evaluate the effects of total parenteral nutrition and octreotide on pediatric patients with chylous ascites post-operative. Methods: Four patients were diagnosed with chylous ascites from nov 2009 to nov 2012. Total parenteral nutrition and octreotide was administered to 2 patients, while the other two only received fasting and total parenteral nutrition. All patients had persistent peritoneal drainage, with the quantity and quality of drainage fluid observed daily. Results: Two patients who received somatostatin therapy completely recovered within 7d without any recurrence while on a normal diet. The other two patients who only received fasting and total parenteral nutrition was cured 24-30d after therapy. Conclusion: Total parenteral nutrition along with octreotide can relieve the symptoms and close the chyle leakage in patients with chylous ascites rapidly. It seems to be an effective therapy available for the treatment of chylous ascites.

    Ascites is a metabolic disorder of modern broilers that is distinguished by cardiopulmonary insufficiency in the face of intense oxygen demands of rapidly growing tissues. Broilers with ascites exhibit sustained elevation of pulmonary arterial pressure and right ventricular hypertrophy, the end result of which is heart failure. It has been shown that mitochondrial function is impaired in broilers with ascites. In the current study, mitochondrial matrix protein levels were compared between ascites-resistant line broilers and ascites-susceptible line broilers with and without ascites using two-dimensional (2-D) gel electrophoresis. One hundred seventy-two protein spots were detected on the gels, and 9 of the spots were present at different levels in the 4 groups of broilers. These 9 protein spots were selected for identification by mass spectrometry. Two of the spots were found to contain single mitochondrial matrix proteins. Both mitochondrial matrix proteins, the dihydrolipoamide succinyltransferase component of the 2-oxoglutarate dehydrogenase complex and the alpha-subunit of mitochondrial trifunctional enzyme, were present at higher levels in ascites-resistant line broilers with ascites in the present study. The elevated levels of 2 key proteins in aerobic metabolism in ascites-resistant line broilers with ascites observed in the present study suggests that the mitochondria of broilers with this disease may respond inappropriately to hypoxia.

    The objective of the present study was to use bivariate mixture models to study the relationships between body weight (BW) and ascites indicator traits. Existing data were used from an experiment in which birds were housed in 2 groups under different climate conditions. In the first group, BW, the ratio of right ventricular weight to total ventricular weight (RV:TV), and hematocrit value (HCT) were measured in 4,202 broilers under cold conditions; in the second group, the same traits were measured in 795 birds under normal temperature conditions. Cold-stress conditions were applied to identify individuals that were susceptible to ascites. The RV:TV and HCT were approximately normally distributed under normal temperature conditions, whereas the distributions of these traits were skewed under cold temperature conditions, suggesting different underlying distributions. Fitting a bivariate mixture model to the observations showed that there was only one homogeneous population for ascites traits under normal temperature conditions, whereas there was a mixture of (2) distributions under cold conditions. One distribution contained nonascitic birds and the other distribution contained ascitic birds. In the distribution of nonascitic birds, the inferred phenotypic correlations (phenotypic correlations with 2 distinguishing underlying distributions) of BW with RV:TV and HCT were close to zero (0.10 and -0.07, respectively), whereas in the distribution of ascitic birds, the inferred phenotypic correlations of BW with RV:TV and HCT were negative (-0.39 and -0.4, respectively). The negative inferred correlations of BW with RV:TV and HCT in the distribution of ascitic birds resulted in negative overall correlations (correlations without 2 distinguishing distributions) of BW with RV:TV (-0.30) and HCT (-0.37) under cold conditions. The present results indicate that the overall correlations between BW and ascites traits are dependent on the relative frequency of ascitic and

    AIM: Vascular endothelial growth factor (VEGF) is a potent mediator of peritoneal fluid accumulation following tumor progression. This study investigated the role of VEGF secreted by cancerous cells in the formation of malignant ascites.METHODS: VEGF expression was eliminated byknockdown in the pancreas cancer cell-line PancO2 using vector-based short-hairpin type RNA interference (RNAi).Malignant ascites formation in the mouse was analyzed by intraperitoneal injection of PancO2 cells expressing VEGF or with expression knockdown.RESULTS: The VEGF knockdown PancO2 cell was successfully established. Knockdown of VEGF did not affect cancer cell proliferation in vitro or in vivo. The volume of ascites following peritoneal expansion of the tumor in VEGF knockdown cells and control cells did not differ statistically in this in vivo study. Moreover, the VEGF concentration in the ascites did not differ statistically.CONCLUSION: Malignant ascites formation might be mediated by VEGF production in noncancerous tissues,such as stromal compartments. An anti-VEGF strategy against malignant ascites could be applied to various tumors regardless of whether they secrete VEGF.

The AVPR2 and AQP2 expression in kidney tissues of ascites mice in different groups was determined by immunohistochemistry, Western blot, and real-time PCR analyses. When the dose of GS was less than 0.70 g/kg at a ratio of GC : GS not exceeding 0.4 : 1, the combination of GS and GC exhibited synergistic effects on HCC ascites and significantly elevated the expression levels of AVPR2 and AQP2 (all P < 0.05). On the contrary, when GS ≥ 0.93 g/kg and GC ≥ 1.03 g/kg with the GC-to-GS ratio exceeding 1.11 : 1, the combination of GS and GC displayed antagonistic effects on HCC ascites and dramatically reduced the expression levels of AVPR2 and AQP2 (all P < 0.05). Furthermore, the administration of herbal pair GS and GC at different ratios did not exacerbate the pathological changes in liver and kidney tissues of HCC ascites mice. The different combinations of GS and GC exerted synergistic or antagonistic effects on HCC ascites, partially by regulating the expression of AVPR2 and AQP2. PMID:27247609

    Right ventricular hypertrophy and failure is an important step in the development of ascites syndrome (AS) in broiler chickens. Cytoplasmic calcium concentration is a major regulator of cardiac contractile function and various physiological processes in cardiac muscle cells. The purpose of this study was to measure the right ventricular pressure and investigate the precise ultrastructural location of Ca(2+) and Ca(2+)-ATPase in the right ventricular myocardium of chickens with AS induced by low ambient temperature. The results showed that the right ventricular diastolic pressure of ascitic broilers was significantly higher than that of control broilers (P ascitic broilers was significantly lower than that of the controls (P ascitic broilers, whereas in the age-matched control broilers, calcium deposits were much less. The Ca(2+)-ATPase reactive products were obviously found on the sarcoplasmic reticulum and mitochondrial membrane of the control right ventricular myocardium, but rarely observed in the ascitic broilers. The data suggest that in ascitic broilers there is the right ventricular diastolic dysfunction, in which the overload of intracellular calcium and the decreased Ca(2+)-ATPase activity might be the important factors.

    AIM: To investigate the effects of long-term albumin administration on survival, recurrence of ascites and onset of other complications.METHODS: One hundred consecutive patients admitted for first-onset ascites were randomized to receive diuretics plus human albumin 25 g/wk in the first year and 25g every two wk thereafter (group 1) or diuretics alone (group 2). The primary endpoint was survival without liver transplantation. Secondary endpoints were recurrence of ascites and occurrence of other complications.RESULTS: Median follow-up was 84 (2-120) mo. Albumin-treated patients had significantly greater cumulative survival rate (Breslow test= 7.05, P= 0.0078) and lower probability of ascites recurrence (51% versus 94%,P<0.0001). Chronic albumin infusion resulted in a mean increase in survival of 16 mo.CONCLUSION: Long-term albumin administration after first-onset ascites significantly improves patients' survival and decreases the risk of ascites recurrence.

  15. Percutaneous radiofrequency ablation of hepatic tumours: Factors affecting technical failure of artificial ascites formation using an angiosheath

    International Nuclear Information System (INIS)

    Aim: To evaluate the technical feasibility of artificial ascites formation using an angiosheath before percutaneous radiofrequency ablation (RFA) for hepatic tumours and to determine predictive factors affecting the technical failure of artificial ascites formation. Materials and methods: This retrospective study was approved by the institutional review board. One hundred and thirteen patients underwent percutaneous RFA of hepatic tumours after trying to make artificial ascites using an angiosheath to avoid collateral thermal damage. The technical success rate of making artificial ascites using an angiosheath and conversion rate to other techniques after initial failure of making artificial ascites were evaluated. The technical success rate for RFA was assessed. In addition, potential factors associated with technical failure including previous history of transcatheter arterial chemoembolization (TACE) or RFA, type of abdominal surgery, and adjacent perihepatic structures were reviewed. Predictive factors for the technical failure of artificial ascites formation were analysed using multivariate analysis. Results: The technical success rates of artificial ascites formation by angiosheath and that of RFA were 84.1% (95/113) and 97.3% (110/113), respectively. The conversion rate to other techniques after the failure of artificial ascites formation using an angiosheath was 15.9% (18/113). Previous hepatic resection was the sole independent predictive factor affecting the technical failure of artificial ascites formation (p<0.001, odds ratio = 29.03, 95% confidence interval: 4.56–184.69). Conclusion: Making artificial ascites for RFA of hepatic tumours using an angiosheath was technically feasible in most cases. However, history of hepatic resection was a significant predictive factor affecting the technical failure of artificial ascites formation. - Highlights: • Making artificial ascites (AA) using an angiosheath is feasible (84.1%, 95/113). • However

    International Nuclear Information System (INIS)

    Objective: To evaluate the value of the interventional peritoneovenous shunts (IPVS)for intractable ascites (IA). Methods: The passageway was built between abdominal cavity and superior vena cava(SVC)in 45 patients with IA. The pressure of abdominal cavity and SVC were measured during operation, the abdominal girth and the amount of urine were recorded after the operation. Results: The successful rate of operation was 100% with operation time of 20-40 min. The average difference of pressure between abdominal cavity and SVC was 129.3 cm H2O. The abdominal girth began to reduce 2 days later, and reduced obviously since then with an average of 7.8 cm. Simultaneously, the amount of urine obviously increased after operation with an average of 770 ml/d. The total effective rate reached 77.8% with no serious complications. Conclusion: IPVS has advantages of simple operation, minimal trauma and convenient for patients with IA nursing themselves etc. and thus improve the living quality of patients exactly. (authors)

  17. Immune mechanisms in Ehrlich ascites tumor growth in mice

    International Nuclear Information System (INIS)

    Normal mice immunised with irradiated Ehrlich ascites tumor (EAT) cells rejected EAT challenge given 2 weeks later but T-cell-deficient thymectomised lethally irradiated, and bone-marrow-reconstituted (TIR) mice succumbed. However, when TIR mice were injected i.v. with thymus, lymph node, or spleen cells from normalsyngetic donors immediately following i.p. injection of irradiated EAT cells, they rejected the subsequent tumor challenge. This induction of immunity in TIR mice was shown to be T-cell dependent. Spleen cells from EAT- bearing mice given immediately after irradiated tumor cells were also able to promote rejection of EAT challenge in TIR mice. Spleen cells from EAT-immune mice inhibited EAT growth when admixed with tumor cells prior to i.p. injection into normal recipients, but had no effect on progressive tumor growth when given i.v. immediately after i.p. tumor injection. Immune serum inhibited i.p. EAT growth when given either i.p. or i.v. Whereas inhibition of EAT growth by admixed spleen cells was shown to be T-cell independent. The data indicate that T lymphocytes are required only in the induction phase of the immune reponse of mice against EAT, while the efferent phase of the response is accomplished by serum antibodies, perhaps through an interaction with host macrophages.

    Ehrlich ascites-tumour cells accumulate Ca2+ when incubated aerobically with succinate, phosphate and rotenone, as revealed by isotopic and atomic-absorption measurements. Ca2+ does not stimulate oxygen consumption by carefully prepared Ehrlich cells, but des so when the cells are placed in a hypo-osmotic medium. Neither glutamate nor malate support Ca2+ uptake in 'intact' Ehrlich cells, nor does the endogenous NAD-linked respiration. Ca2+ uptake is completely dependent on mitochondrial energy-coupling mechansims. It was an unexpected finding that maximal Ca2+ uptake supported by succinate requires rotenone, which blocks oxidation of enogenous NAD-linked substrates. Phosphate functions as co-anion for entry of Ca2+. Ca2+ uptake is also supported by extra-cellular ATP; no other nucleoside 5'-di- or tri-phosphate was active. The accumulation of Ca2+ apparently takes place in the mitochondria, since oligomycin and atractyloside inhibit ATP-supported Ca2+ uptake. Glycolysis does not support Ca2+ uptake. Neither free mitochondria released from disrupted cells nor permeability-damaged cells capable of absorbing Trypan Blue were responsible for any large fraction of the total observed energy-coupled Ca2+ uptake. The observations reported also indicate that electron flow through energy-conserving site 1 promotes Ca2+ release from Ehrlich cells and that extra-cellular ATP increase permeability of the cell membrane, allowing both ATP and Ca2+ to enter the cells more readily.

    The potential role of cell surface sialomucin in preventing natural killer (NK)-mediated lysis of tumor cell targets has been addressed by comparing the properties of 2 NK-resistant [ascites (ASC) and short-term cultured (STC)] and 2 NK-susceptible [tunicamycin-treated (TUN) and long-term cultured (LTC)] preparations of 13762 MAT-B1 rat mammary tumor cells. Both the ASC and STC cell preparations contain elevated levels of the sialomucin ASGP-1 relative to TUN and LTC preparations as determined by [3H]glucosamine labeling and by binding of peanut agglutinin. The major difference in the susceptibility to NK-mediated lysis appeared to be due to the differences in the susceptibility to lysis by lytic granules, rather than to differences in the ability to bind or trigger effector cells, since TUN and LTC cells were approximately 10-fold more sensitive to lysis by lytic granules than were ASC and STC cells. All preparations inhibited the lysis of the susceptible target YAC-1 by normal rat splenocytes, indicating an ability to bind these effector cells. Triggering of effectors, as monitored either by incorporation of 32P into phosphatidylinositol or by transmethylation of phosphatidylcholine, was similar for the positive control YAC-1, STC, TUN, and LTC, whereas ASC appeared to be defective in triggering effectors. These results suggest that tumor sialomucin blocks the final phase of lysis, but not the initial recognition of tumor cells by NK effectors. PMID:2208144

    (1) Ascites syndrome is a growth-related disorder of broilers that occurs more often in fast-growing birds and at low temperatures. The objective of this study was to estimate genetic and phenotypic correlations among ascites-related traits measured either under cold or under normal temperature conditions, and to estimate genetic correlations between ascites-related traits measured under cold and normal conditions. (2) Several traits related to ascites were measured on more than 4000 chickens under cold conditions and on more than 700 chickens under normal conditions. (3) The heritability estimates for body weight (BW) measured under cold and normal conditions were 0.42 and 0.50, respectively, for haematocrit value 0.46 and 0.17, respectively, and for ratio of right to total ventricular weight 0.45 and 0.12, respectively. (4) The genetic correlation between BW and haematocrit value under cold conditions was -0.23 and between BW and ratio of right to total ventricular weight -0.27. Under normal conditions, however, these genetic correlations were 0.55 and 0.50, respectively. (5) These results demonstrate that the heritability estimates of ascites-related traits as well as genetic correlations between ascites-related traits and BW depend on the temperature conditions under which animals are kept. (6) Strong positive genetic correlations (around 0.8) were observed between total mortality, fluid in the abdomen and ratio of right to total ventricular weight under cold conditions. The genetic correlation between ratio of right to total ventricular weight under cold and normal conditions was 0.91. (7) These results suggest that the ratio of right to total ventricular weight measured under normal temperature conditions might serve as a good indicator trait for ascites. PMID:15835250

    Background Chylous ascites is the pathologic leakage of triglycerides-rich lymphatic fluid into the peritoneal cavity. Chylous ascites is a rare complication in abdominal surgery. This study aimed to find a relatively better method for nutrition support in the treatment of chylous ascites after abdominal surgery. Methods This study was a retrospective study. This study retrospectively reviewed patients who underwent abdominal surgery and developed chylous ascites, from the year 2010 to 2014, at the West China Hospital of Sichuan University and the Affiliated Hospital of Zunyi Medical College. Fifty-eight patients who developed chylous ascites after abdominal surgery were included in the study. The clinical effect of somatostatin was evaluated. The differences in the curative efficacy among a daily diet, a low-fat diet supplemented with medium-chain triglyceride (MCT), and total parenteral nutrition (TPN) were also analyzed in this study. Results Complete clinical success was reached earlier in patients treated with somatostatin (P<0.001). The tube removal time, the time to resumption of an oral diet, and the length of hospital stay after chylous leakage were significantly different between patients treated with and without somatostatin. The curative efficacies of the enteral nutrition (EN) + MCT plan and the TPN plan were quite similar, with no significant difference, however, were significantly different from the MCT regime, which was the worst. However, using the EN + MCT plan was more cost-effective (P=0.038). Conclusion In treating chylous ascites, EN + MCT instead of TPN was the best nutrition support. Moreover, somatostatin or its analog octreotide should be used immediately. The treatment with somatostatin in combination with EN + MCT is recommended in the conservative treatment of postoperative chylous ascites. PMID:27143902

    Gastrointestinal dysfunction in patients with cirrhosis may contribute to complications such as malnutrition and spontaneous bacterial peritonitis. To determine whether cirrhotic patients with ascites have altered intestinal function, we compared intestinal permeability and absorption in patients with liver disease and normal subjects. Intestinal permeability and absorption were investigated in 66 cirrhotic patients (48 with ascites, 18 without ascites) and 74 healthy control subjects. Timed recovery of 3-O-methyl-D-glucose, D-xylose, L-rhamnose, and lactulose in urine following oral administration was measured in order to assess active and passive carrier-mediated, and nonmediated, absorptive capacity, as well as intestinal large-pore/small-pore (lactulose/rhamnose) permeability. Test sugars were measured by quantitative thin-layer chromatography and results are expressed as a percentage of test dose recovered in a 5-h urine collection. Sugar excretion ratios relating to small intestinal permeability (lactulose/rhamnose) and absorption (rhamnose/3-O-methyl-D-glucose) were calculated to avoid the effects of nonmucosal factors such as renal clearance, portal hypertension, and ascites on the recovery of sugar probes in urine. Compared with normal subjects, the mean lactulose/rhamnose permeability ratio in cirrhotic patients with ascites was significantly higher (0.058 vs. 0.037, P < 0.001) but not in cirrhotic patients without ascites (0.041 vs. 0.037). Cirrhotic patients with ascites had significantly lower mean recoveries of 3-O-methyl-D-glucose (23.0 vs. 49.1%; P < 0.001), D-xylose (18.8 vs. 34.5%; P < 0.001), L-rhamnose (4.0 vs. 9.1%; P < 0.001), and lactulose (0.202 vs. 0.337%; P < 0.001) than normal subjects. However, the mean rhamnose/3-O-methyl-D-glucose ratio was the same in cirrhotic patients with ascites as normal subjects (0.189 vs. 0.189), indicating that the reduction in probe recovery was due to nonmucosal factors. Compared with normal subjects

  4. Cytokinetic Control Mechanisms in Ehrlich Ascites Tumour Growth

    International Nuclear Information System (INIS)

    Ehrlich ascites tumour in mice was studied as a model system to elucidate the cytokinetic mechanisms controlling growth of cell populations. The basis for a retardation in growth rate during tumour development was determined with the aid of 3H-thymidine labelling and autoradiography. Three possible cytokinetic variables in growth regulation, namely, duration of the mitotic cell cycle, fraction of the cycling cells in the population (growth fraction) and rate of cell loss, were measured at different stages of growth. It was concluded that a deceleration in growth was a result of (1) a gradual prolongation of the cell cycle and its components and (2) a progressive decline in the growth fraction. Rate of cell loss did not appreciably change during most of the growth. It was also found that the total cell mass rather than the tumour age dictated the growth rate at any instant over a considerable range of growth. Non-cycling cells were found to resume cycle when a fraction of an old tumour was transplanted in new hosts, 3H-thymidine labelling combined with microspectrophotometric estimates of cellular DNA was utilized to locate the stages at which a cell cycle could be suspended or resumed. It was found that decycling or recycling could occur only after mitosis and before DNA synthesis; non-cycling (G0) state resembled G1, which was absent in the proliferating tumour cells. These findings are relevant to a further understanding of the molecular events leading to the initiation or suspension of a cell cycle. They are also pertinent to formulating a rationale for tumour therapy — for example with radiation — when coupled with the existing knowledge of the relative sensitivity of cells at different stages of cycle.

    Pulmonary hypertension syndrome (PHS), or ascites, is characterized by elevated pulmonary arterial pressure and pulmonary vascular resistance accompanied by right ventricular hypertrophy (RVH) and fluid accumulation in the abdominal cavity. Experimental models are required for triggering PHS to study the pathogenesis of this syndrome and to select resistant genetic lines. Caffeine increases vascular resistance and promotes systemic hypertension in mammals, but a similar effect of caffeine on the pulmonary circulation had not previously been demonstrated. Two experiments were conducted to evaluate the impact of caffeine alone (Exp. 1) or in combination with cold temperature (Exp. 2) on parameters associated with PHS in young broiler chicks. In Exp. 1, 288 chicks were distributed among 24 pens and brooded at standard environmental temperatures, and on d 3 through 42 caffeine was added to the water at doses of 0 (control), 6.25, 12.5, 25, 50, and 100 mg/(kg BW·d). In Exp. 2, 192 chicks were distributed among 16 pens and brooded at cool environmental temperatures, and on d 3 through 42 caffeine was added to the water at doses of 0 (control), 15, 30, and 45 mg/(kg BW·d). In Exp. 1 caffeine administered at or above 12.5 mg/(kg BW·d) induced severe PHS and resulted in acute mortality and RVH ( broilers exposed to cold temperatures remarkably exhibited PHS incidences and developed RVH with right ventricular to total ventricular weight ratios of 30% or greater. Moreover, hematocrit significantly increased because of caffeine supplementation in cool ambient temperature ( = 0.002). Our data demonstrate that caffeine induces high incidences of PHS in broilers, which is exacerbated by exposure to low temperatures. PMID:27136008

    A six-year-old Rottweiler with chronic ascites and moderate panhypoproteinaemia that had been treated with large volume paracentesis over several months duration was diagnosed with a large bi-atrial mass and hepatic fibrosis. For palliative treatment, a peritoneo-vesical automated fluid shunt system with an integrated chargeable battery and an integrated computer to control pump function and to transmit data transcutaneously was implanted by coeliotomy. The pump was left in place for 10 weeks, eliminating the need for further paracentesis during this time. At the end of this period, no ascites was discernible and serum protein concentrations had returned to their respective reference intervals. As a complication, decubitus with skin perforation had developed above the pump. Besides palliative treatment of chronic refractory ascites, this pump may have application in other conditions characterised by chronic cavity effusion or in peritoneal dialysis. PMID:22106956

  7. Peritoneal implants without ascites. Preoperative CT diagnosis in colon carcinoma patients

    International Nuclear Information System (INIS)

    We evaluated the preoperative CT findings in 10 patients with colon carcinoma in whom peritoneal metastases had been surgically confirmed. Seven patients lacked ascites. No CT findings suggestive of peritoneal metastasis were observed in two patients without ascites even by retrospective evaluation. A large mass was observed in the cul-de-sac in another. In the remaining four patients, small peritoneal metastases ranging from 8 to 11 mm in diameter were observed at the omentum in two, along the falciform ligament in one, and at both the omentum and the iliac fossa in one; three of these patients had received no prospective diagnosis of peritoneal metastasis prior to the surgery. In patients with advanced colon carcinoma with suspected serosal invasion, the entire peritoneal cavity should be carefully examined and interpreted using CT in order to detect small peritoneal implants even when ascites is absent.

    We report a case of a very rare tumor of the ovary with an unusual presentation; an ovarian hemangioma with massive ascites and elevated CA125. A 57-year-old woman presenting with elevated CA125, massive ascites and a left solid adnexal mass of 60 x 47 mm, with calcification and increased blood flow at Doppler examination, was submitted to laparotomy. Frozen section was inconclusive and a staging procedure which complicated the patient was performed. Pathologic examination revealed cavernous hemangioma which is an extremely rare tumor of the ovary. Although it is very unusual, an ovarian hemangioma may present with ascites and elevated CA125 and the differential diagnosis from ovarian cancer should be considered. PMID:16620071

    Full Text Available Infectious bronchitis is an acute viral disease with high contagious and mortality among chicks. The aim of this study was to survey of relation between ascites syndrome incidence and infectious bronchitis in broiler chickens by ELISA method in Iran. Eight Ross strain broiler farm affected by infectious bronchitis were selected in this study. Blood samples were gathered early stages of disease and blood sampling was repeated two times with seven days interval. ELISA serologic test was used for approving the determination of infectious bronchitis. In addition, in order to differential diagnosis of Newcastle and influenza (H9N2 some relevant experiments were conducted. The rate of mortality in any farm during rearing, autopsy and the cause of mortality were recorded. Ascites cases were calculated in terms of prevalence. The growth parameters, FCR, final weight, total consumption of grain at each farm were calculated and mentioned. Based on obtained results in this study, the mean rate of mortality caused by ascites syndrome has been increased meaningfully in herds affected by infectious bronchitis compared with control group. In eight understudied farms affected by infectious bronchitis, the mean rate of Ascites mortality was 3% such that the mean rate of Ascites mortality was 0.5% at previous periods. Based on relevant results also final weight mean in affected herds with infectious bronchitis was lower compared with previous periods. Meanwhile, FCR in affected herds with infectious bronchitis was high compared with healthy herds. In this research demonstrated that there is positive correlation between infectious bronchitis and Ascites syndrome and the correlation is significant (p<0.05.

    The leaves of Chenopodium ambrosioides L. [Chenopodiaceae] ('mastruz') have been indicated for the treatment of several diseases, among which the cancer. There are no results focusing the effect of C. ambrosioides treatment on tumor development in vivo. The aim of this study was to investigate the effect of treatment with C. ambrosioides on Ehrlich tumor development. Swiss mice were treated by intraperitoneal route (i.p.) with hydroalcoholic extract from leaves of C. ambrosioides (5 mg/kg) or with PBS (control group) 48 h before or 48 h later the Ehrlich tumor implantation. The tumor cells were implanted on the left footpad (solid tumor) or in the peritoneal cavity (ascitic tumor). To determine the solid tumor growth, footpad was measured each 2 days until the fourteenth day, when the feet were weighed. Ascitic tumor development was evaluated after 8 days of tumor implantation by quantification of the ascitic fluid volume and tumor cell number. The i.p. administration of C. ambrosioides extract before or after the tumor implantation significantly inhibited the solid and ascitic Ehrlich tumor forms. This inhibition was observed in ascitic tumor cell number, in the ascitic volume, in the tumor-bearing foot size and foot weight when compared to control mice. The treatments also increased the survival of tumor-bearing mice. In conclusion, C. ambrosioides has a potent anti-tumoral effect which was evident with a small dose and even when the treatment was given two days after the tumor implantation. This effect is probably related with anti-oxidant properties of C. ambrosioides. PMID:16307762

    Full Text Available Ascites is a complex problem caused by many interacting factors such as genetics, environment and management. Many nutritional, medicinal and management strategies have been proposed to alleviate the problem. Higher levels of dietary vitamin C and E along with selenium yeast might be beneficial, presumably because of their role in improving cellular integrity. Oils rich in n-3 fatty acids have been shown to reduce pulmonary hypertension and, consequently, ascites incidence. The potential use of flax oil has already been demonstrated, whereas the effects of other oils rich in n-3 fatty acids (fish, linseed and canola oils remain to be investigated. The assessment of the effects of dietary electrolyte balance on ascites incidence seems to be a promising field of research in broiler nutrition. In general, reducing the dietary level of salt (NaCl and adding bicarbonates to the diet and drinking water have been proposed as potential "cost-effective" methods to reduce ascites incidence. The use of nutrients/drug agents that increase the vascular capacity of the lungs or decrease the pulmonary vascular resistance may help to alleviate the problem, but economic and local feed regulations might restrict such use. Diuretics have also shown positive effects, presumably because there is a reduction of sodium and fluid retention in the body; litter humidity however must be closely monitored if diuretics are continuously administered. As the high metabolic rate (fast growth is a major factor contributing to the susceptibility of broilers to ascites, early-age feed or nutrient restriction (qualitative or quantitative or light restriction in order to slow down the growth rate seem practically viable methods, since final body weight is not compromised. Optimization of the house temperature and ventilation in cold weather seem helpful practices to decrease ascites incidence. Under practical conditions, it might be interesting to test the additive effects of

    Full Text Available Abstract Introduction Chylothorax and chylous ascites are uncommon and usually associated with trauma or neoplasms. To the best of our knowledge, constrictive pericarditis leading to chylothorax and chylous ascites in a person infected with HIV has never previously been described. Case presentation A 39-year-old Thai man was referred to our institute with progressive dyspnea, edema and abdominal distension. His medical history included HIV infection and pulmonary tuberculosis that was complicated by tuberculous pericarditis and cardiac tamponade. Upon further investigation, we found constrictive pericarditis, chylothorax and chylous ascites. A pericardiectomy was performed which resulted in gradual resolution of the ascites and chylous effusion. Conclusions Although constrictive pericarditis is an exceptionally rare cause of chylothorax and chylous ascites, it should nonetheless be considered in the differential diagnosis as a potentially reversible cause.

Chylous ascites is a rare complication in abdominal surgery. This study aimed to find a relatively better method for nutrition support in the treatment of chylous ascites after abdominal surgery. Methods: This study was a retrospective study. This study retrospectively reviewed patients who underwent abdominal surgery and developed chylous ascites, from the year 2010 to 2014, at the West China Hospital of Sichuan University and the Affiliated Hospital of Zunyi Medical College. Fifty-eight patients who developed chylous ascites after abdominal surgery were included in the study. The clinical effect of somatostatin was evaluated. The differences in the curative efficacy among a daily diet, a low-fat diet supplemented with medium-chain triglyceride (MCT, and total parenteral nutrition (TPN were also analyzed in this study. Results: Complete clinical success was reached earlier in patients treated with somatostatin (P<0.001. The tube removal time, the time to resumption of an oral diet, and the length of hospital stay after chylous leakage were significantly different between patients treated with and without somatostatin. The curative efficacies of the enteral nutrition (EN + MCT plan and the TPN plan were quite similar, with no significant difference, however, were significantly different from the MCT regime, which was the worst. However, using the EN + MCT plan was more cost-effective (P=0.038. Conclusion: In treating chylous ascites, EN + MCT instead of TPN was the best nutrition support

    Mesenteric fibromatosis is a rare benign nonmetastatic neoplasm that appears as a sporadic lesion or occurs in patients with familial polyposis, while chylous ascites associated with aggressive mesenteric fibromatosis during pregnancy has never been reported thus far. Here we present the case of a 28-year old pregnant woman, in whom an aggressive mesenteric fibromatosis with chylous ascites was detected, involving the jejunum, superior mesenteric artery (SNA) and superior mesenteric vein (SMV) and pancreas. One year after a successful surgical excision, the patient had no signs of recurrence. The authors report the case for its rarity and emphasize on combining clinicopathological, radiological and immunohistochemistry analysis for management of the disease.

    Full Text Available A patient with alcoholic cirrhosis of the liver, portal hypertension with hepatic encephalopathy and spontaneous bacterial peritonitis (SBP was admitted in an obtunded condition. Attempts at delineating the aetiology of the SBP using conventional cultures as well as automated systems were not successful. The use of non-anionic surfactant agents such as Tween 80-incorporated blood agar and Triton X treatment of the specimens facilitated the growth of Klebsiella pneumoniae from the ascitic fluid, which otherwise would have been concluded to represent culture-negative neutrocytic ascites. Thus, the use of the aforementioned agents could be explored in elucidating the aetiology of body cavity infections when conventional methods fail.

    1. Male broilers of two different genetic stocks, a pure broiler sire line (A) and commercially available Ross broilers (B), were used to study the effect of differences in haematocrit values in 12-d-old chickens on the development of ascitic symptoms. Body weight gain (BWG), feed intake (FI) and feed conversion ratio (FRC) were measured from 2 to 5 weeks of age. Mortality was recorded from 2 to 6 weeks. The birds were kept at a low ambient temperature to stimulate the incidence of ascites. 2. From each stock 32 birds with the highest (High Ht) and 32 birds with the lowest (Low Ht) haematocrit values in venous blood were selected at 12 d of age for an examination on susceptibility for the ascites syndrome at 5 weeks. 3. At 2 weeks 448 birds per stock (including High Ht and Low Ht birds) were allotted to 32 floor pens (1 High Ht and 1 Low Ht in each pen). Venous blood samples were taken weekly in High Ht and Low Ht birds for haematocrit measurements and at week 5 also thyroid hormone (T3, T4) concentrations in plasma were measured. At 5 weeks all High Ht and Low Ht birds were examined post-mortem and arterial pressure index, heart weight, lung weight and liver weight (all relative to body weight) were recorded. High values for arterial pressure index, relative heart and liver weights and low values for relative lung weights and plasma thyroid hormone were considered to be indicators for ascites susceptibility. 4. Stock A, with the highest ascites mortality, had lower values for BWG and FCR than stock B. Throughout, a clear difference in Ht values between High Ht and Low Ht birds was maintained. No significant effects of 12-d haematocrit values were found on the incidence of ascitic symptoms until week 5. High Ht values tended to correlate with low relative lung weights and low plasma T3 concentrations in High Ht birds. 5. Within the groups of selected birds, there was an effect of stock on ascitic symptoms (arterial pressure index, relative heart weight and T3

    Polymorphonuclear (PMN) cell count in the ascitic fluid is essential for the diagnosis and management of spontaneous bacterial peritonitis (SBP). To date, PMN cell count is routinely performed by traditional manual counting. However, this method is time-consuming, costly, and not always timely available. Therefore, considerable efforts have been made in recent years to develop an alternative test for a more rapid diagnosis and monitoring of SBP. The use of urinary reagent strips was proposed to achieve an "instant" bedside diagnosis of SBP. A series of reports evaluated the urine strip test for SBP diagnosis and reported promising results. However, a recent large multicenter study revealed a surprising lack of diagnostic efficacy of the urine screening test for SBP diagnosis. Another method, more recently proposed as an alternative to the manual PMN count, is the measurement of lactoferrin in ascitic fluid, but the data available on the diagnostic value of this test are limited to a single study. However,both urinary reagent strips and ascitic lactoferrin tests are qualitative methods and need, therefore, to be further confirmed by standard cytology of the ascitic fluid.To date, the only quantitative method proposed as a valid alternative to manual PMN counting is automated blood cell counters, commonly used in all laboratories for blood cell counting. Data available in the literature on the diagnostic performance of this method are limited but very promising, and this tool seems to have the potential to replace the manual counting method.

Successful treatment of chronic hepatitis C in patients with advanced fibrosis or cirrhosis has significant benefits, including improvements in inflammation, fibrosis, and portal hypertension, with prevention of esophageal varices and clinical decompensation.Case: In this report, we present two patients with well-compensated hepatitis C cirrhosis who achieved an end-of-treatment response on a direct-acting antiviral therapy-based triple regimen for hepatitis C virus, but subsequently presented with new-onset ascites associated with virologic relapse.Conclusion: We propose that the development of ascites in this setting is due to the adverse impact of inflammation of the virologic relapse on portal hypertension. Our observation that ascites formation can be a manifestation of virologic relapse has potentially important clinical implications, as it highlights not only the importance of close monitoring of cirrhotic patients after achieving end-of-treatment response but also the impact of active inflammation on the severity of portal hypertension.Keywords: chronic hepatitis C, cirrhosis, virologic relapse, portal hypertension, ascites

    Spontaneous bacterial peritonitis (SBP) is a severe complication of liver disease. A significant proportion of patients have culture-negative ascites, despite having similar signs, symptoms and mortality to those with SBP. Therefore, empirical antibiotic treatment for infection is often started without knowledge of the causative organisms. Here, we investigated the potential of molecular techniques to provide rapid and accurate characterisation of the bacteria present in ascitic fluid. Ascites samples were obtained from 29 cirrhotic patients undergoing clinically indicated therapeutic paracentesis. Bacterial content was determined by terminal restriction fragment length polymorphism (T-RFLP) analysis, quantitative polymerase chain reaction (PCR) and 16S ribosomal clone sequence analysis. Bacterial signal was detected in all samples, compared to three out of ten using standard methods. Bacterial loads ranged from 5.5 x 10(2) to 5.4 x 10(7) cfu/ml, with a mean value of 1.9 x 10(6) cfu/ml (standard deviation +/- 9.6 x 10(6) cfu/ml). In all but one instance, bacterial species identified by culture were also confirmed by molecular analyses. Preliminary data presented here suggests that culture-independent, molecular analyses could provide rapid characterisation of the bacterial content of ascites fluid, providing a basis for the investigation of SBP development and allowing early and targeted antibiotic intervention.

    The authors consider the various causes of ascites and they also develop the concept of refractory ascites. They consider the various possibilities of medical and dietary therapy whose failure constitutes the basis for a surgical approach. In the latter case it is being considered the Peritoneo Venous Shunt (PVS) that employs different types of valves. In the light of their personal experience, matured over a period of 15 years, in which 75 valves were positioned in 64 patients and precisely: 55 valves of Le Veen, 15 Hakim and 5 Denver, it is emphasized that the best results, as for as mortality and morbidity goes, were obtained through careful attention in the preoperative stage and during surgery itself with the privileged use of a Le Veen's valve. For such motives, since in a high percentage of these patients there persists a poor prognosis a year away from the onset of refractory ascites, a PVS seems proposable anyway and even though this will not alter the pathological outcome, there's a clear improvement in the quality of life without precluding any other surgical approach. Finally, the authors outline the possibilities offered by the Transjugular Intrahepatic Portosystemic Shunt (TIPS), as a new original approach for the resolution of refractory ascites. PMID:8286483

    A 49-year-old woman was admitted to our hospital because of coughing and dyspnea. A chest roentogenogram showed emphysematous changes and a diffuse reticular shadow. A high-resolution CT scan of the chest showed many small cysts throughout the lungs. Lymphangiomyomatosis was diagnosed after examination of a specimen obtained by transbronchial biopsy. Abdominal distention due to chylous ascites developed during the hospital stay despite anti-estrogen therapy. Because the ascites was resistant to conservative therapy, we decided to begin peritoneo-venous shunting with a Denver Shunt system. After the operation, the abdominal distention was controlled for 1 year and 11 months, at which time the patient died of respiratory and heart failure with pneumonia. At autopsy, the shunt was patent and functional although about 900 ml of serous ascites fluid was present. An adenocarcinoma was found in the upper lobe of the right lung, but it may not have been related to the lymphangiomyomatosis. Peritoneovenous shunting with a Denver Shunt can be used to treat chylous ascites due to lymphangiomyomatosis when conservative therapy is insufficient. PMID:8753114

    An experiment with 250 one-day-old male broilers (Ross 308) was conducted to investigate the differences of some blood parameters of cold-induced ascitic and healthy broiler chicks in a 6-wk period. The chickens were divided into 2 groups of 5 replicates each. One group of these chickens was raised in normal temperature (NT) treatment and the other in cold temperature (CT) treatment to induce ascites. Mortality was necropsied daily to determine cause of death. At the end of the experiment (wk 6), 5 chickens from each replicate were randomly selected and slaughtered. The heart was removed; the right ventricle was dissected away from the left ventricle and septum. Weights of right and left ventricles were determined separately. Average BW gain and average feed intake were measured weekly, and weekly average feed conversion ratio was calculated. Serum glucose, total protein, cholesterol, triglyceride, activity of lactate dehydrogenase, as-partate aminotransferase, and alanine aminotransferase were determined. Throughout the study, the right ventricle-to-total ventricle ratio and total mortality percentage due to ascites of CT-treated birds at the end of experiment was greater (P ascites could affect serum protein and fasting blood sugar of broiler chickens.

  13. Optimization of monoclonal antibody production in mouse ascites by single whole-body irradiation

    International Nuclear Information System (INIS)

    Hybridoma cells injected intraperitoneally into mice induce formation of ascites tumors producing ascites fluid with high levels of monoclonal antibodies. Several parameters affect the growth of the immunoglobulin-producing tumors in vivo. In 10 different hybridomas the average ascites tumor formation rate could be increased from 32% (n = 338 mice) to 77% (n = 112 mice) by only one whole-body irradiation of paraffin-pretreated Balb/c mice. Production of monoclonal antibodies was better in males because of the significantly (p < 0.01) increased volume of ascites fluid. From the increased tumor formation rate in irradiated mice it is suggested that in non-irradiated recipients the tumor growth rate was lowered by immunological reactions against hybridoma cells provoked by cell surface neoantigens revealed by cell fusion and/or tumor-associated antigens of the myeloma parent cells as well as by altered antigen pattern caused by possible mutations in the myeloma cell line and/or Balb/c/K strain.

    1. Male broilers of two different genetic stocks, a pure broiler sire line (A) and commercially available Ross broilers (B), were used to study the effect of haematological characteristics in juvenile chickens on the development of clinical ascitic signs. Production performance (body weight gain (BWG), feed intake (FI), feed conversion ratio (FCR)) from 448 birds per stock was measured from 2 to 5 weeks of age. Mortality was recorded from 2 to 6 weeks of age. The birds were housed at a low ambient temperature to stimulate the incidence of ascites. 2. From each stock, 32 birds with the highest (high risk: HRc) and 32 birds with the lowest (low risk: LRc) carbon dioxide tensions (pCO2) in venous blood were selected at 11 d of age. These birds were marked for future blood sampling to determine changes in pCO2 with age to relate these values to ascites susceptibility. 3. At 2 weeks of age all birds (including HRc and LRc birds) were allotted to 32 floor pens (one HRc and one LRc in each pen) per stock. Venous blood samples were collected weekly from HRc and LRc birds for blood gas analysis and haematocrit, and at week 5 also for thyroid hormone (T3, T4) concentrations in plasma. At 5 weeks of age all HRc and LRc birds were examined post-mortem, relative heart, lung, and liver weights and arterial pressure index (API) values were recorded. 4. Birds from stock A showed a lower BWG and FCR and notably higher ascites mortality compared with stock B. An effect of pCO2 tensions at d 11 was found on the incidence of ascitic signs in selected birds of both stocks up to week 5. From the HRc groups 30% of the birds showed ascitic signs, whereas this was only 8% in the LRc group. LRc birds of stock B in particular showed constant low API values (20 +/- 3%) and none of these birds showed signs of ascites. 5. Our results suggest that the ascites problem in Ross birds can be eliminated by selection for low pCO2 tensions in venous blood. Stock effects on API, liver weight, lung

    Full Text Available We report the case of a 24-year-old male patient admitted for recent ascites and splenomegaly of unknown origin. The patient was referred to our institution with complaints of diarrhea, epigastric pain, abdominal cramping and weight loss over the past three weeks. The acute onset presented with colicky abdominal pain and peritoneal effusion. History revealed reduced appetite and weight gain of 7 kg over the last one month. His past medical history and family history was negative. He had no history of alcohol abuse or viral hepatitis infection. Laboratory data revealed normal transaminases and bilirubin levels, and alkaline phosphatase and gammaglutamyltransferase were within normal range. A diagnostic laparoscopy was performed which showed free peritoneal fluid and normal abdominal viscera. Upper gastrointestinal system endoscopy performed a few days later revealed diffuse severe erythematous pangastritis and gastroduodenal gastric reflux. Duodenal biopsies showed chronic nonspecific duodenitis. Antrum and corpus biopsies showed chronic gastritis. The ascitic fluid was straw-colored and sterile with 80% eosinophils. Stool exam was negative for parasitic infection. Treatment with albendazole 400 mg twice daily for 5 days led to the disappearance of ascites and other signs and symptoms. Three months after albendazole treatment the eosinophilic cell count was normal. The final diagnosis was consistent with parasitic infection while the clinical, sonographic and histological findings suggested an eosinophilic ascites. We emphasize the importance of excluding parasitic infection in all patients with eosinophilic ascites. We chose an alternative way (albendazole treatment to resolve this clinical picture. With our alternative way for excluding this parasitic infection, we treated the patient and then found the cause.

    Full Text Available Abstract Background The production of ascites is a common complication of ovarian cancer. Ascites constitute a unique tumor microenvironment that may affect disease progression. In this context, we recently showed that ovarian cancer ascites may protect tumor cells from TRAIL-induced apoptosis. In this study, we sought to determine whether the prosurvival effect of ascites affects disease-free intervals. Methods Peritoneal fluids were obtained from 54 women undergoing intra-abdominal surgery for suspected ovarian cancer (44 cancers and 10 benign diseases. The ability of peritoneal fluids to protect from TRAIL was assessed in the ovarian cancer cell line CaOV3, and IC50 were determined. The anti-apoptotic activity of 6 ascites against cisplatin, paclitaxel, doxorubicin, etoposide and vinorelbine was also assessed in CaOV3 cells, and the prosurvival activity of two ascites was assessed in 9 primary ovarian cancer cultures. Results Among the 54 peritoneal fluids tested, inhibition of TRAIL cytotoxicity was variable. Fluids originating from ovarian cancer were generally more protective than fluids from non-malignant diseases. Most of the 44 ovarian cancer ascites increased TRAIL IC50 and this inhibitory effect did not correlate strongly with the protein concentration in these ascites or the levels of serum CA125, a tumor antigen which is used in the clinic as a marker of tumor burden. The effect of ascites on cisplatin- and paclitaxel-induced cell death was assessed with 4 ascites having inhibitory effect on TRAIL-induced cell death and 2 that do not. The four ascites with prosurvival activity against TRAIL had some inhibitory on cisplatin and/or paclitaxel. Two ovarian cancer ascites, OVC346 and OVC509, also inhibited TRAIL cytotoxicity in 9 primary cultures of ovarian tumor and induced Akt activation in three of these primary cultures. Among a cohort of 35 patients with ascites, a threshold of TRAIL IC50 with ascites/IC50 without ascites > 2 was

    Full Text Available Six hundred 1-d-old male broilers (Ross 308 were assigned to four experimental groups; each was composed of 5 floor pen replications of 30 birds including control (no enalapril, 15, 30 and 60 ppm enalapril in the drinking water. From d 21 to 49, all the chicks were exposed to low ambient temperature to induce ascites. Mortalities were inspected to determine the cause of death and diagnose of ascites. At the end of the experiment (wk 7, 2 chickens from each replicate were randomly selected and slaughtered. Body weight gain, feed intake and feed conversion ratio were calculated. Plasma protein, glucose, red blood cell, white blood cell, triglyceride, high-density lipoprotein, malondialdehyde, the activity of alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase, creatine kinase, total antioxidant capacity, superoxide dismutase, and glutathione peroxidase were also determined. Results showed that enalapril for 30 and 60 ppm, significantly improved feed conversion ratio and enhanced body weight gain when measured at day 49. These levels of enalapril compared to the other groups, significantly reduced malondialdehyde level and glutathione peroxidase activity, but increased total antioxidant capacity and superoxide dismutase activity in plasma. Moreover, enalapril at levels of 30 and 60 ppm, significantly reduced aspartate aminotransferase, alkaline phosphatase and creatine kinase activities in plasma. Mortality due to ascites and right to total ventricular weight ratio were significantly low in groups received enalapril at greater levels (≥30 ppm. Compared to the control, enalapril increased high-density lipoprotein. In conclusion, enalapril could improve growth performance and reduced mortality in broilers.

  1. Protective Effect of Propolis (Bee Glue) in Mice Bearing Ehrlich Ascites Carcinoma

    International Nuclear Information System (INIS)

    Cancer is considered one of the most common causes of morbidity and mortality worldwide. Many studies were carried out to investigate the discovery of natural and synthetic compounds that can be used in the prevention and/or treatment of cancer. Natural products of either plant or animal origin that exhibit antitumour activity have been discovered. The present study was undertaken to evaluate the protective effect of ethanolic extract of propolis without or with radiation exposure in Ehrlich ascites carcinoma- bearing female albino mice. The animals were randomly distributed into three major groups as follows: group A (control group): consists of 10 mice kept on normal standard rodent diet without any treatment and housed in two cages: mice of the first cage served as control for non tumour-bearing group and the second cage served as control for tumour-bearing group. Group B (non tumour-bearing group): consists of 15 mice and used to study the effect of the vehicle solution (gum acacia), propolis and gamma irradiation on normal mice. Mice of this group were equally distributed into three subgroups receiving gum acacia, propolis for two weeks and gamma irradiated. Group C (tumour bearing group): consists of 20 mice randomly and equally distributed into 4 subgroups: Ehrlich ascites carcinoma, Ehrlich ascites carcinoma and 2 Gy irradiated, Ehrlich ascites carcinoma and propolis treated, and Ehrlich ascites carcinoma and propolis irradiated. Plasma and hepatic lipid peroxidation index (TBARS), superoxide dismutase (SOD) and glutathione (GSH) were assessed in RBC and liver together with hepatic aspartate amino transferase (AST) and alanine amino transferase (ALT) and histopathological examination of liver sections. There was decrease in the levels of SOD and GSH as well as an increase in TBARS in mice bearing EAC in addition to increase in hepatic levels of AST and ALT. The microscopical examination of liver sections of mice bearing EAC showed various histopathological

    Ascites, also called pulmonary hypertension syndrome, is a metabolic disorder in chickens that have an insufficient pulmonary vascular capacity. The tendency of broilers to develop ascites is heritable, and successful selection against this susceptibility would benefit from good and easy-to-measure indicator traits. Blood gas parameters have been suggested as indicator traits for ascites susceptibility. Therefore, the aim of the present study was to estimate the heritability of blood gas parameters and the genetic and phenotypic correlations between blood gas parameters, heart ratio (postmortem indicator for ascites), and BW at 2 different ages. For this purpose, blood gas parameters, including the partial pressure of carbon dioxide in venous blood (pvCO(2)), the partial pressure of oxygen in venous blood (pvO(2)), and blood oxygen saturation, were measured at an average age of 22 d in nearly 3,000 broilers. To challenge the resistance of the birds to ascites, they were kept under cold conditions. Heritability for heart ratio was 0.43, and the heritability estimates were low: 0.02 for pvCO(2), 0.03 for pvO(2), and 0.07 for blood oxygen saturation. The estimated heritability for pH was 0.15, for bicarbonate was 0.19, and for total carbon dioxide content was 0.19. The genetic correlations between heart ratio and total carbon dioxide content (0.31 +/- 0.15) and between heart ratio and bicarbonate (0.31 +/- 0.15) were moderate and positive. For pvO(2), the genetic correlation with heart ratio was stronger and negative (-0.62 +/- 0.21); however, this correlation could not be estimated accurately because of the low heritability of pvO(2). For pvCO(2), the genetic correlation with the heart ratio was close to zero (-0.04 +/- 0.45). Phenotypic correlations between traits were, in general, similar to the genetic correlations. Heritabilities for blood gas parameters and the genetic correlations between blood gas parameters and the heart ratio estimated in the present study

  3. Microheterogeneity of transthyretin in serum and ascitic fluid of ovarian cancer patients

    International Nuclear Information System (INIS)

    Transthyretin (TTR), a traditional biomarker for nutritional and inflammatory status exists in different molecular variants of yet unknown importance. A truncated form of TTR has recently been described to be part of a set of biomarkers for the diagnosis of ovarian cancer. The main aim of the study was therefore to characterize differences in microheterogeneity between ascitic fluid and plasma of women affected with ovarian cancer and to evaluate the tumor site as the possible source of TTR. Subjects were 48 women with primary invasive epithelial ovarian cancer or recurrent ovarian carcinoma. The control group consisted of 20 postmenopausal women. TTR and retinol-binding protein (RBP) levels were measured by enzyme-linked immunoassay (ELISA) and C-reactive protein (CRP) levels by a high-sensitivity latex particle turbidimetric assay. The molecular heterogeneity of TTR was analysed using immunoprecipitation and matrix-associated laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS). Presence of TTR in tumor tissue was determined with indirect peroxidase immunostaining. TTR and RBP (μg/ml) levels in serum were 148.5 ± 96.7 and 22.5 ± 14.8 in affected women compared to 363.3 ± 105.5 and 55.8 ± 9.3 in healthy postmenopausal women (p < 0.01). In ascitic fluid, levels were 1.02 ± 0.24 and 4.63 ± 1.57 μg/ml, respectively. The mean levels of TTR and RBP in serum showed a tendency to decrease with the severity of the disease and were lower in affected women whose CRP levels were > 40 mg/ml (p = 0.08 for TTR; p < 0.05 for RBP). No differences in TTR microheterogeneity were observed between TTR isolated from serum of affected and healthy women or from ascitic fluid. TTR occurred rather consistently in four variants. Mass signals were at 13758 ± 7, 13876 ± 13 (greatest intensity), 13924 ± 21 and 14062 ± 24 Da, representing native, S-cysteinylated, S-cysteinglycinylated and glutathionylated TTR, respectively.

    Full Text Available Tumor cells in ascites are a major source of disease recurrence in ovarian cancer patients. In an attempt to identify and profile the population of ascites cells obtained from ovarian cancer patients, a novel method was developed to separate adherent (AD and non-adherent (NAD cells in culture. Twenty-five patients were recruited to this study; 11 chemonaive (CN and 14 chemoresistant (CR. AD cells from both CN and CR patients exhibited mesenchymal morphology with an antigen profile of mesenchymal stem cells and fibroblasts. Conversely, NAD cells had an epithelial morphology with enhanced expression of cancer antigen 125 (CA125, epithelial cell adhesion molecule (EpCAM and cytokeratin 7. NAD cells developed infiltrating tumors and ascites within 12-14 weeks after intraperitoneal (i.p. injections into nude mice, whereas AD cells remained non-tumorigenic for up to 20 weeks. Subsequent comparison of selective epithelial, mesenchymal and cancer stem cell (CSC markers between AD and NAD populations of CN and CR patients demonstrated an enhanced trend in mRNA expression of E-cadherin, EpCAM, STAT3 and Oct4 in the NAD population of CR patients. A similar trend of enhanced mRNA expression of CD44, MMP9 and Oct4 was observed in the AD population of CR patients. Hence, using a novel purification method we demonstrate for the first time a distinct separation of ascites cells into epithelial tumorigenic and mesenchymal non-tumorigenic populations. We also demonstrate that cells from the ascites of CR patients are predominantly epithelial and show a trend towards increased mRNA expression of genes associated with CSCs, compared to cells isolated from the ascites of CN patients. As the tumor cells in the ascites of ovarian cancer patients play a dominant role in disease recurrence, a thorough understanding of the biology of the ascites microenvironment from CR and CN patients is essential for effective therapeutic interventions.

  5. Malignant biliary obstruction complicated by ascites: Closure of the transhepatic tract with cyanoacrylate glue after placement of an endoprosthesis

    International Nuclear Information System (INIS)

    A new technique using cyanoacrylate glue is suggested for closing the transparenchymal tract following metallic endoprosthesis placement in a patient with malignant biliary obstruction complicated by ascites. With this technique, complications related to bile reflux through the transparenchymal tract would be avoided after transhepatic endoprosthesis placement in patients who have ascites. This technique would also be useful for avoiding bleeding following transhepatic portal venous puncture

    Several pathogenic processes have been implicated in the development of abdominal ascites. Portal hypertension, most usually in the context of liver cirrhosis, can explain about 75% of the cases, whereas infective, inflammatory and infiltrative aetiologies can account for the rest. In this article, we discuss the consensus best practice as published by three professional bodies for the management of ascites, spontaneous bacterial peritonitis (SBP) and hepatorenal syndrome (HRS). The aim of this study was to compare available clinical guidelines and identify areas of agreement and conflict. We carried out a review of the guidance documentation published by three expert bodies including the British Society of Gastroenterology, the European Association for the Study of the Liver (EASL) and the American Association for the Study of Liver Diseases (AASLD), as well as a wider literature search for ascites, SBP and HRS. Abdominal ultrasonography, diagnostic paracentesis and ascitic fluid cultures are recommended by all three guidelines, especially when there is strong clinical suspicion for infection. EASL and AASLD advocate the use of ascitic amylase and mycobacterial cultures/PCR when there is strong suspicion for tuberculosis and pancreatitis, respectively. Ascitic cytology can be useful when cancer is suspected and has a good diagnostic yield if performed correctly. EASL supports the use of urinary electrolytes for all patients; however, the British Society of Gastroenterology and AASLD only recommend their use for therapy monitoring. All three societies recommend cefotaxime as the antibiotic of choice for SBP and large-volume paracentesis for the management of ascites greater than 5 l in volume. For HRS, cautious diuresis, volume expansion with albumin and the use of vasoactive drugs are recommended. There appears to be good concordance between recommendations by the European, American and British guidelines for the management of ascites and the possible

    Congenital ascites is rare, but when it occurs, urinary ascites secondary to posterior urethral valve obstruction is the most common, and tumors are the least. Among the tumors in the pediatric population, the central nervous system tumors are common, but spinal cord tumors are rare. We describe a very rare case of congenital malignant spinal cord glioma presenting as isolated congenital ascites secondary to neurogenic bladder. A female infant was diagnosed sonographically with isolated congenital ascites at 40 weeks' gestational age, with uneventful development prior to 40 weeks' gestational age. Magnetic resonance imaging of the spine done within the first week of life identified a lobulated spinal mass with heterogeneous enhancement within the conus medullaris. Spinal fluid analysis showed evidence of small round blue cells and the pathology from the excision biopsy of the mass confirmed a WHO grade III or IV malignant glioma. The postoperative course was uneventful with resolution of the ascites and spontaneous micturition. The patient was discharged home without an indwelling urinary catheter. We report the first documented case of a newborn infant with isolated congenital ascites from neurogenic bladder secondary to a spinal cord glioma. PMID:27597917

    Chylous ascites is a rare complication in liver transplant. Few cases have been reported to date. In most cases, chylous ascites is diagnosed within 1 month after surgery because of intraoperative injury of the hilar lymphatic system. Preoperative massive ascites and use of a LigaSure vessel sealing system for hilar dissection have been reported as risk factors. We report a case of chylous ascites after a living-donor liver transplant that was diagnosed after 6 months of uneventful follow-up. Sirolimus was added to cyclosporine early (2 wk after the operation) owing to poor renal function and it was found to be high (> 22 ng/mL) when the chylous ascites occurred. The patient was treated with total parenteral nutrition in combination with Sandostatin and rapid tapering of sirolimus after the failed initial conservative treatment. Residual abdominal fullness after meals and lymphedema of the legs disappeared 1 month after discontinuing sirolimus. This is the first case of delayed-onset chylous ascites after a liver transplant that was successfully treated conservatively. PMID:25365187

  10. Evolution of sarcoma 180 (ascitic tumor in mice infected with Schistosoma mansoni

    Full Text Available Mice infected with 60 cercariae of Schistosoma mansoni were more resistant to the sarcoma 180 ascites tumor. Tumor inoculation was performed 50 days after schistosoma infection and the animals were observed and weighed at 48 hours intervals for development and progression of malignancy. In infected mice the weight gain (ascites formation started later and was shorter than in uninfected Controls. Also, the number of tumor cells into the peritoneal cavity 72h after tumor implantation was shorter in infected group than incontrols. This in creased resistance against a transplantable tumor probably is related to the effect of endotoxin on tumoricidal activity of macrophages activated by the infection. The immunodepression induced by Schistosoma mansoni infection enhances the proliferation of endogenous bacteria increasing the amount of endotoxin absorbed from the gut.

    Refractory ascites (RA) is thought to complicate the postoperative course of 5-7% (Nishida et al. in Am J Transplant. 6: 140-149, 2006; Gotthardt et al. in Ann Transplant. 18: 378-383, 2013) of liver transplant recipients. RA after liver transplantation is often a frustrating diagnostic dilemma with few good management options unless an obvious mechanical factor is identified. Supportive therapies often fail until a treatable precipitating cause is identified and removed. We describe two patients who developed RA following liver transplantation for primary sclerosing cholangitis, and hepatitis C and alcoholic liver disease, respectively. The cause for RA was hyperkinetic portal hypertension secondary to splenomegaly in the first case and a pancreatic AVM in the 2nd case. After failure of other interventions, surgical splenectomy resulted in immediate and durable resolution of the previously intractable ascites. PMID:26017456

    We present the first case report of chylous ascites following total robot-assisted donor nephrectomy. A 39-year-old female underwent a transperitoneal left-sided total robot-assisted donor nephrectomy. The procedure was uneventful and the patient was discharged without any symptoms. At postoperative Day 29, the patient presented with abdominal pain, nausea and a distended, painful abdomen with shifting dullness. She was diagnosed with chylous ascites by ultrasonography and puncture analysis, and treated with therapeutic drainage and dietary restriction. After 4 weeks, she was free of symptoms. The occurrence of this complication is rare after donor nephrectomy. Fortunately, the complication can be successfully treated within a few weeks with minimal discomfort for the patient as demonstrated in this case. It is of utmost importance to minimize the risks and limit discomfort for live kidney donors who willingly undergo major surgery to improve the well-being of another individual. PMID:27381018

    This investigation evaluates whether the appearance and thickness of the gallbladder (GB) wall can be clinically useful to determine the etiology of ascites by ultrasonography. Another purpose of this study is to verify the existence of statistically significant relationship between GB wall patterns and serum albumin level. Findings on ultrasonogram were reviewed retrospectively in 90 patients with ascites. The statistical analysis of the results reveals no correlation between hypoalbuminemia and GB wall patterns (P>0.05). There was a significant difference in GB wall patterns between benign (group 1 and 2) and malignant (group 3 and 4) conditions (P>0.05). The carcinoma, with the exception of hepatocellular the gallbladder wall was significantly thicker in the cirrhosis brougs than in the malignant group. Twenty-seven patients (87%) in group 1 had thickened GB walls, whereas 16 patients (76%) in group 3 showed normal single layered GB walls. This difference was statistically significant (P>0.05). However no statistically significant difference was found between liver cirrhosis (group 1) and liver cirrhosis associated with hepatocellular carcinoma (group 4) (P>0.05). Also, with the except of hepatocellular carcinoma (group 3) there also was no significant difference found between benign noncirrhotic pathology (group 2) and malignancy. These results suggests that there is a distant sonographic appearance of the GB wall according to different ascitis etiologies. This can pathology be seen when comparing patients with liver carrhosis and malignancy other than hepatocellular carcinoma. However sonographic findings of the GB wall patterns in ascites lacks diagnostic value in differentiating benign from malignant disease causing ascites.

    Full Text Available The work's objective is to answer the question whether there is any possibility of activity inhibition of cysteine peptidases inhibitors playing an important role in key processes accompanying cancer formation, including pancreas. There is a justified speculation that specific inhibitors of these enzymes may inhibit development of cancer processes by inhibiting their activity. In vitro studies confirmed that these enzymes in ascitic fluid were inhibited with egg whites inhibitors even to 90% of their original activity.

    Full Text Available Acute pancreatitis is an inflammatory disease often associated with local and systemic complications. Portosplenic and splanchnic vascular complications of acute pancreatitis are common, but extrasplanchnic vessel thrombosis is less commonly seen. Among them, pulmonary thromboembolism is a very rare complication to be encountered with. We report four cases of acute pulmonary thromboembolism in patients with acute pancreatitis superimposed on chronic pancreatitis. All the patients had abdominal pain on presentation and distention of abdomen during the course. Dyspnea was present in all the patients. All patients were found to have pancreatic ascites, whose association with pulmonary thromboembolism is reported only in two patients till date upto our knowledge. Two of them had deep vein thrombosis and rest two had no venous thrombosis. All of them were managed conservatively using subcutaneous heparin, intravenous fluids and analgesics. We provide the causative mechanism for occurrence of pulmonary thromboembolism in acute on chronic pancreatitis. We have also hypothesized pancreatic ascites as the possible cause for pulmonary thromboembolism and provide explanation for it. We conclude that pulmonary thromboembolism in acute pancreatitis has good prognosis if diagnosed timely. Whenever patient with pancreatic ascites presents with dyspnea, pulmonary thromboembolism must be ruled out.

    Preincubation of Ehrlich ascites tumor cells at 22 or 32 degrees C, but not at 0 degree C, with pantothenic acid, 4'-phosphopantothenic acid, pantothenol, or pantethine reduced lipid peroxidation (measured by production of thiobarbituric acid-reactive compounds) induced by the Fenton reaction (Fe2+ + H2O2) and partly protected the plasma membrane against the leakiness to cytoplasmic proteins produced by the same reagent. Pantothenic acid and its derivatives did not inhibit (Fe2+ + H2O2)-induced peroxidation of phospholipid multilamellar vesicles, thus indicating that their effect on the cells was not due to the scavenging mechanism. Homopantothenic acid and its 4'-phosphate ester (which are not precursors of CoA) neither protected Ehrlich ascites tumor cells against lipid peroxidation nor prevented plasma membrane leakiness under the same conditions. Incubation of the cells with pantothenic acid, 4'-phosphopantothenic acid, pantothenol, or pantethine significantly increased the amount of cellular CoA and potentiated incorporation of added palmitate into phospholipids and cholesterol esters. It is concluded that pantothenic acid and its related compounds protect the plasma membrane of Ehrlich ascites tumor cells against the damage by oxygen free radicals due to increasing cellular level of CoA. The latter compound may act by diminishing propagation of lipid peroxidation and promoting repair mechanisms, mainly the synthesis of phospholipids. PMID:8582649

    We report successful anesthetic management of extended operation for peritoneal pseudomyxoma combined with massive ascites (16.5 l). A 66-year-old man (weight 76 kg) who could not keep a supine position due to massive ascites associated with peritoneal pseudomyxoma was scheduled for elective peritonectomy and extended surgery. With the patient in the semisitting position, we administered 3% sevoflurane to induce loss of consciousness while preserving spontaneous ventilation. We then performed crush induction with propofol and rocuronium after topical anesthesia to the tongue base. Tracheal intubation with the Macintosh laryngoscope was successful. During the operation, we aspirated about 16.5 l of ascites over 20 l normal saline irrigation. To maintain the body temperature, we performed both active and passive extracorporeal warming. The operation included not only total peritonectomy but also distal gastrectomy, right colon resection, splenectomy, and cholecystectomy. To perform effective postoperative analgesia, we placed two epidural catheters from the upper and lower thoracic epidural spaces. The patient was extubated 3 days after operation, and discharged uneventfully on the 18th postoperative day. PMID:27483656

    Abstract Introduction The incidence of hernias is increased in patients with alcoholic liver disease with ascites. To the best of our knowledge, this is the first report of an acute rise in intra-abdominal pressure from straining for stool as the cause of a ruptured umbilical hernia. Case presentation An 81-year-old Caucasian man with a history of alcoholic liver disease presented to our emergency department with an erythematous umbilical hernia and clear, yellow discharge from the umbilicus. On straining for stool, after initial clinical assessment, our patient noted a gush of fluid and evisceration of omentum from the umbilical hernia. An urgent laparotomy was performed with excision of the umbilicus and devitalized omentum. Conclusion We report the case of a patient with a history of alcoholic liver disease with ascites. Ascites causes a chronic increase in intra-abdominal pressure. A sudden increase in intra-abdominal pressure, such as coughing, vomiting, gastroscopy or, as in this case, straining for stool can cause rupture of an umbilical hernia. The presence of discoloration, ulceration or a rapid increase in size of the umbilical hernia signals impending rupture and should prompt the physician to reduce the intra-abdominal pressure.

    Objectives: Thickened greater omentum is encountered with high frequency in patients with ascites. The purpose of our study was to assess the utility of greater omentum biopsy under the guidance of ultrasound (US) in tracing the origin of unclear ascites and differentiating benign and malignant ascites. Materials and methods: We retrospectively reviewed our institutional database for all records of greater omentum biopsy cases. One hundred and ninety-four patients with unclear ascites and thickened greater omentum were included in the study. The sonograms of greater omentum were evaluated before undergoing the ultrasound-guided biopsy and a biopsy was considered successful if a specific benign or malignant diagnosis was rendered by the pathologist. Results: Successful biopsy was rendered for 182 biopsy procedures (93.8%, 182/194) including tuberculosis (n = 114), chronic inflammation (n = 3), metastases (n = 58), malignant mesothelioma (n = 6) and pseudomyxoma peritonei (n = 1). Twelve biopsies were non-diagnostic. According to the results of biopsy and follow-up, the sensitivity and specificity of biopsy in distinguishing malignant ascites from benign ascities were respectively 95.6% (65/68) and 92.9% (117/126). The greater omentum of 84 cases of tuberculous peritonitis showed 'cerebral fissure' sign and was well seen as an omental cake infiltrated with irregular nodules when involved by carcinomatosis. No 'cerebral fissure' sign was observed in peritoneal carcinomatosis. The sensitivity and specificity of this sign in indicating the existence of tuberculous peritonitis were 73.5% (89/121) and 100% (73/73). Moreover, if the specific 'cerebral fissure' sign was combined with the biopsy results, the specificity of biopsy in distinguishing malignant ascites from benign ascits increased to 96.8% (122/126). Conclusion: Ultrasound-guided biopsy of greater omentum is an important and effective method to diagnose the unclear ascites for

    2002-01-01

    Objective The renal hemodynamic alteration was sequentially studied in dogs with ascites due to portal hypertension.Methods The model of portal hypertension was established by the constriction of hepatic vein. Effective renal plasma flow (ERPF), systemic blood pressure, urinary excretion of sodium were measured. Eighteen dogs were studied until the ascites occurred.Results The ascites was generally detected between the sixth day and the eighth day after the portal hypertension occurred, the average being the seventh day. Mean artery pressure (MAP) and renal vascular resistance (RVR) were firstly changed after the portal vein pressure increased. MAP fell 17% (130.37mmHg±16.2 mmHg before the portal hypertension, 108.32 mmHg±10.47 mmHg after the portal hypertension on the 1st day, p<0.001) and RVR increased by 31% (0.38 mmHg. ml-1. min-1±0.09 mmHg. ml-1. min-1 before the portal hypertension, 0.5 mmHg. ml-1. min-1±0.15mmHg. ml-1. min-1 after the portal hypertension, P<0.05) after the portal hypertension occurred on the 2nd day, thereafter, MAP decreased and RVR increased continually. ERPF also fell in the forepart, but there was only significant difference in the appearance of ascites (P<0.05). Urinary excretion of sodium gradually fell after portal hypertension and reached the lowest value on the 7th day, and there was statistical significance from the 2nd day (59.86 mmol/min±25.96 mmol/min before portal hypertension, 31.95 mmol/min±18.79mmol/min after the portal hypertension on the 2nd day, p<0.05).Conclusion Our research indicates that the hemodynamics has been changed before the ascites occurred. The earliest change occurs in MAP and RVR, but no marked change is found in ERPF.

    Ascites is a metabolic disorder that accounts for over 25% of overall mortality in the broiler industry. This disorder is manifested between wk 5 and 6 posthatch, but there are previous indications that predisposition may be identified during embryonic development. In this current study, we determined embryonic physiological and metabolic parameters that may be associated with ascites predisposition. For this purpose, we used broiler eggs from 3 lines that differed in ascites sensitivity. These included an ascites-sensitive dam line (DAS), an ascites-resistant dam line (DAR), and an ascites-sensitive sire line (SASL). Eggs were incubated for 21 d under standard conditions. The following parameters were measured during incubation: egg weights at setting, egg weight losses at 18 d, embryo body weights and embryo heart weights throughout development, air cell partial gas pressures (pCO2 and pO2) levels at d 18 and at internal pipping (IP); plasma triiodothyronine, thyroxine, and corticosterone levels at d 18, IP, and hatch; heat production from d 17 until hatch, hematocrit values at hatch, and posthatch growth rate to 7 d along with hematocrit values. The data obtained revealed that selection for ascites sensitivity or rapid growth rate had no consistent influence on some of these parameters such that they could be wholly associated with ascites sensitivity for predictive purposes. Whereas differences in embryonic developmental patterns were apparent throughout embryonic development, these differences in physiological and metabolic parameters may be due partly to genetic differences unrelated to ascites sensitivity.

    G. lucidum total triterpenes were assessed for its apoptosis-inducing and anti-tumour activities. The ability of the total triterpenes to induce apoptosis was evaluated in Dalton's lymphoma ascites (DLA) and Ehrlich's ascites carcinoma (EAC) cell lines. Total triterpenes were found to be highly cytotoxic to DLA and EAC cell lines with IC50 values 5 ± 0.32 and 7.9 ± 0.2 µg/ml respectively. Total triterpenes induced apoptosis in both cell lines which is evident from the DNA fragmentation assay. Anti-tumour activity was accessed using DLA induced solid and EAC induced ascites tumour models in Swiss albino mice. Administration of 10, 50 and 100 mg/kg b. wt. total triterpenes showed 11.86, 27.27 and 40.57% increase in life span of animals in ascites tumour model. Treatment with 10, 50 and 100 mg/kg b. wt. total triterpenes exhibited 76.86, 85.01 and 91.03% inhibition in tumour volume and 67.96, 72.38 and 77.90% inhibition in tumour weight respectively in the solid tumour model. The study reveals the significant dose-dependent anti-tumour activity of total triterpenes in both models. Total triterpenes were more active against the solid tumour than the ascites tumour. The anti-oxidant potential and ability to induce cell-specific apoptosis could be contributing to its anti-tumour activities. PMID:27188870

    Full Text Available Doxorubicin (Dox treatment is limited by severe toxicity and frequent episodes of treatment failure. To minimize adverse events and improve drug delivery efficiently and specifically in cancer cells, encapsulation of Dox with naturally obtained galactoxyloglucan polysaccharide (PST001, isolated from Tamarindus indica was attempted. Thus formed PST-Dox nanoparticles induced apoptosis and exhibited significant cytotoxicity in murine ascites cell lines, Dalton’s lymphoma ascites and Ehrlich’s ascites carcinoma. The mechanism contributing to the augmented cytotoxicity of nanoconjugates at lower doses was validated by measuring the Dox intracellular uptake in human colon, leukemic and breast cancer cell lines. PST-Dox nanoparticles showed rapid internalization of Dox into cancer cells within a short period of incubation. Further, in vivo efficacy was tested in comparison to the parent counterparts - PST001 and Dox, in ascites and solid tumor syngraft mice models. Treatment of ascites tumors with PST-Dox nanoparticles significantly reduced the tumor volume, viable tumor cell count, and increased survival and percentage life span in the early, established and prophylactic phases of the disease. Administration of nanoparticles through intratumoral route delivered more robust antitumor response than the intraperitoneal route in solid malignancies. Thus, the results indicate that PST-Dox nanoparticles have greater potential compared to the Dox as targeted drug delivery nanocarriers for loco regional cancer chemotherapy applications.

    The MAT-B1 and MAT-C1 ascites sublines of the 13762 rat mammary adenocarcinoma contain a dominant cell surface "complex" consisting of two glycoproteins: ascites sialoglycoprotein (ASGP)-1, a Mr 600,000-700,000 peanut agglutinin-binding sialomucin, and ASGP-2, a Mr 120,000 concancavalin A-binding glycoprotein (Sherblom et al., J. Biol. Chem., 255: 783-790, 1980; Sherblom and Carraway, J. Biol. Chem., 255: 12051-12059, 1980). Although both cell lines are resistant to lysis by natural killer cells, treatments which result in loss of cell surface ASGP-1 render the cells susceptible to natural killer cell lysis (Sherblom and Moody, Cancer Res., 46:4543-4546, 1986). Treatment of the ascites cells with 5 micrograms/ml tunicamycin for 24 h effectively inhibits glycosylation of ASGP-2 without affecting cell viability or total protein synthesis. Under these conditions, expression of ASGP-1 is depressed by at least 50% in both cell lines, as monitored by [3H]glucosamine incorporation and by binding of peanut agglutinin to intact cells. The size distribution of O-linked oligosaccharides in ASGP-1 from tunicamycin-treated versus control MAT-B1 cells is indistinguishable, as determined by Bio-Gel P-4 chromatography following alkaline-borohydride treatment. Complex isolated from either treated or control cells bands at the same density in a CsCl gradient containing Triton X-100 and contains a diffuse band corresponding to ASGP-2 by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Tunicamycin-treated cells, consistent with the reduced expression of ASGP-1, are significantly more susceptible to natural killer cell-mediated lysis, when compared to untreated controls. The results suggest that N-linked glycosylation is a prerequisite for sialomucin synthesis and/or complex formation. PMID:2386935

  18. The evaluation of in vitro effect of daunorubicin and tamoxifen in ehrlich ascites tumour (EAT) cells

    International Nuclear Information System (INIS)

    In the most countries, breast cancer is still the most important cancer among women. It is known that Ehrlich Ascites Tumour is experimental breast cancer model in animal. The cells used in the study are hyper diploid line of Ehrlich Ascites Tumour (EAT) cells, initially provided to us from Institute of Pathology, Koln University. In the present study, an hyper diploid line which is estrogen receptor positive was used. An anthracycline-derived antibiotic, Daunorubicin (DNR, Cerubidine) is one of the clinically used anticancer drugs. DNR has been used alone or in combination with other cytotoxic agents against a variety of animal and human tumours. In vitro cell culture studies show that DNR enters the cell nuclei, inhibits nucleic acid synthesis, and arrest cell division. Tamoxifen (TAM, Nolvadex) is a semi-synthetical estrogen antagonist, used in the management of pre and post menopausal breast cancer. This drug bind to intracellular estrogen receptors, and prevents endogenous estrogens from binding to their own receptors. It is known that Ehrlich Ascites Tumour is experimental breast cancer model in animal. The cells used in the study are hyper diploid line of EAT cells initially provided to us from Institute of Pathology, Koln University. In the present study, an hyper diploid line which is Estrogen Receptor (+) was used. Estrogen Receptor levels were studied by the methods of Lippman and Huff and Raynaud et al. with minor modifications. Estrogen Receptor activity as demonstrated by dextran-coated charcoal technique is closely correlated with the clinical ability of Tamoxifen to inhibit tumour growth

  19. DNA double strand breaks in Ehrlich ascites tumour cells at low doses of X-rays

    International Nuclear Information System (INIS)

    DNA double strand breaks (dsb) were determined in Ehrlich ascites tumour cells at doses down to 5 Gy. Sedimentation profiles were analysed using a computer program and the number of dsb was determined by simulation of random breaks in the mass distribution of the control sample and by comparison of this simulated profile with that of the irradiated one. The number of dsb formed was proportional to X-ray dose in the range of 5 to 2000 Gy. The induction per dose was found to be nmsub(r)-1 D-1=(11.7+-2) x 10-12 Gy-1. (author)

  4. In vivo Anticancer Activities of Benzophenone Semicarbazone against Ehrlich Ascites Carcinoma Cells in Swiss Albino Mice

    International Nuclear Information System (INIS)

    Benzophenone semicarbazone (BSC) was synthesized and characterized to identify compounds with anticancer activities. Anticancer activities were studied against Ehrlich Ascites Carcinoma (EAC) cells in Swiss albino mice by monitoring parameters such as tumor weight measurement, survival time of tumor bearing mice, tumor cell growth inhibition, and so on. Some hematological parameters, such as red blood cells, white blood cells, and hemoglobin content, were also measured. The results showed that BSC has a positive effect against EAC cells. An assessment was conducted by comparing these results with those obtained using the standard drug bleomycin. The BSC compound can be considered as a potent anticancer agent

    The aim of the current study was to determine how a control temperature and acute and chronic high eggshell temperatures during the last three days of incubation, can affect hatchability, chick quality, and organ development on day of hatch as well as broiler performance and ascites incidence in later life. The eggshell temperature manipulations were applied during hatching term (days 19 to 21) as follows: control EST (37.3 to 38.0°C), acute high eggshell temperature manipulations (38.4- to 39.0°C for three hours daily) and chronic high eggshell temperature manipulations (38.4 to 39.0°C). The lowest hatchability and the highest cull chick rate were in the chronic high eggshell temperature manipulations group. Lower chick quality parameters correlated with lower chick weights and heavier residual yolk sac weights that were in the chronic high eggshell temperature manipulations group depending on hatch time. The live weights on the 1(st) day of the growing period were higher in the control and acute high eggshell temperature manipulations groups than the chronic high eggshell temperature manipulations group. At 6 wk of age, live weights of broilers were the highest in the control than in the acute and chronic high eggshell temperature manipulations groups. The total mortality was 2.5, 9.2, and 13.3%, the mortality due to ascites was 2.1, 8.3, and 12.9% in the control, acute ,and chronic high eggshell temperature manipulations groups, respectively. The right ventricular/total ventricular ratios for the control, acute and chronic high eggshell temperature manipulations groups were 0.22, 0.28, and 0.30%, respectively. In conclusion, short-term and long-term higher temperatures during the hatching term affect embryo development, incubation results, broiler performance, and ascites incidence. Although the acute high eggshell temperature manipulations did not affect the chick quality parameters at hatch, it negatively affected incubation results and broiler performance

    A hypothesis was tested that providing the breeder hens with exogenous thyroxine (T(4)) would help their offspring to better survive the ascites-inducing condition during the growing period. In total, 132 broiler breeder hens were randomly assigned to one of 3 treatments: control (CON), hypothyroid [HYPO; 6-N-propyl-2-thiouracil (PTU)-treated], and hyperthyroid (HYPER; T(4)-treated). The hens were artificially inseminated, and the hatching eggs (n = 1,320) were incubated. No eggs in the HYPO group hatched. The 1-d-old male chicks (n = 288) from other groups were reared for 42 d under standard or low ambient temperature to induce ascites. Blood samples were drawn from the hens, embryos, and broilers for determination of T(4) and triiodothyronine (T(3)). The hematocrit was also determined in broilers. The PTU-treated hens had an increased BW along with lower plasma T(3) and T(4) concentrations. Plasma T(4) was higher in the HYPER hens compared with CON hens, but T(3) concentration was not different between these groups. The fertility rate was not affected by either hypo- or hyperthyroidism. The embryos in the HYPO group had lower plasma T(3) and T(4) concentrations at d 18 of embryonic development and internal pipping. Higher plasma T(4) was recorded in the HYPER birds at internal pipping, although plasma T(3) concentration was not affected at this stage. Maternal hyperthyroidism decreased the overall incidence of ascites in the cold-exposed chickens (10.0 vs. 33.4% for HYPER and CON groups, respectively). Although the effect of maternal PTU or T(4) treatment on plasma thyroid hormones and on the right ventricle-to-total ventricular weight ratio in the broilers was not significant, the cold-exposed healthy CON chicks showed higher hematocrit values, compared with the HYPER birds. It was concluded that maternal hyperthyroidism could decrease the incidence of cold-induced ascites in broiler chickens; however, probable causal mechanisms remain to be elucidated. PMID

    Full Text Available Thirty two with the ascitic form of Stages IIIC—IV ovarian cancer underwent 1 to 3 courses of intraperitoneal multidrug therapy using a protein ascitic fluid concentrate (PAFC as a solvent of drugs (cisplatin, cyclophosphan, doxorubicin according to the CAP regimen. The induction chemotherapy allowed remission to be achieved in 78.1% of cases (against 40% with standard intraperitoneal therapy, the stan- dard volume of surgical treatment was performed in 28 (87.5% patients (21 (70% receiving the control regime; with the use of PAFC, the size of minimum residual tumour (less than 1 cm was achieved in 81.3% versus 63.3% with standard intraperitoneal chemotherapy. This treatment enables the use large-dose chemotherapy regimens that cause no severe systemic toxic reactions. The method is highly-effective, low-toxic and may be recommended for the treatment of patients with the ascitic form of Stages III—IV ovarian cancer.

    Full Text Available Chyloperitoneum is the accumulation of lymphatic fluid in the peritoneal cavity. Chylous ascites can occur if it is not recognized during surgery. The incidence of chylous ascites after oncological surgery was approximately 7.4% however, the incidence of lymphorrhea after radical gastrectomy for gastric cancer is so low. Extensive lymph node dissection leads to a higher incidence of lymphorrhea. There have been few cases associated with D1 dissection In most patients conservative treatment is recommended that includes paracentesis, total parenteral nutrition (TPN, a medium chain triglyceride (MCT based diet, and somatostatin. Surgery is the last choice only when conservative treatment fails. In this case we aimed to present a late onset of chylous ascites after subtotal gastrectomy and D1+ dissection that was treated with percutaneous drainage and conservative management.

  12. TIPSS Procedure in the Treatment of a Single Patient After Recent Heart Transplantation Because of Refractory Ascites Due to Cardiac Cirrhosis

    International Nuclear Information System (INIS)

    We present the case of a female patient with arrhythmogenic dysplasia of the right ventricle who evolved to refractory heart failure, ascites, and peripheral edema. As a result, heart transplantation was performed. Subsequently, refractory ascites impaired the patient's respiratory function, resulting in prolonged mechanical ventilation. She was successfully treated with transjugular intrahepatic portosystemic shunt (TIPSS) placement, which allowed satisfactory weaning of ventilatory support.

    Ascites is a prevalent cardiovascular disease among modern broilers with negative impacts on production and animal welfare. The peak of mortality due to ascites occurs at the end of the growing period, but the etiology of this problem may start during embryonic development. A few recent reports have demonstrated that the signs of ascites susceptibility are manifested during the late stages of incubation. In the current study, we used a nondestructive method based on egg acoustic resonance parameters [resonant frequency (RF) and damping] to establish a relationship between embryo physiological events during early development in broiler eggs and susceptibility to ascites. The hatching eggs of 3 broiler lines differing in ascites susceptibility were used for this study: ascites-resistant dam line (DAR), ascites-sensitive dam line (DAS), and ascites-sensitive sire line (SASL). These lines were selected on the basis of fast growth, high breast meat yield, and ascites induction at low temperatures such that the order of ascites susceptibility in terms of mortality was SASL > DAS > DAR. Eggs were incubated under standard conditions in forced-draft incubators. We measured egg weights at setting, albumen pH, Haugh units (HU) at setting, and embryo weights at d 11 and 18, at internal pipping (IP), and at hatch. The durations of IP, external pipping (EP), and hatching were also determined. At 2 hourly periods during incubation, egg RF and damping were also measured. There were differences in egg weights between DAR and SASL vs. DAS, but albumen HU, albumen pH, and the ratio of yolk weight to egg weight were similar. There were differences in RF, damping, embryonic growth rates, and hatching events. Changes in resonant frequency and damping, which certainly suggest eggshell differences among lines, were not totally related to variations in physiological events during early and late embryonic development.

    Despite initial response to chemotherapy, at least 50% of ovarian cancer patients will relapse within 18 months. Progression-free survival is related to tumour infiltration with cytotoxic T lymphocytes (CTL). We recently demonstrated that CD8+ T cell responses to recall antigens improve following tumour response to chemotherapy. Vaccination designed to expand CTL, specific for tumour-associated antigens, may be a means of improving outcome. We are planning a clinical trial in advanced ovarian cancer patients undergoing chemotherapy using a combination of a Toll-like receptor 3 (TLR3) agonist and tumour-associated ascites-derived exosomes. Tumour-derived exosomes are a potential source of tumour antigens able to induce CD8+ T cell responses when loaded on mature dendritic cells (DC). DC maturation can be achieved with Toll-like receptor (TLR) agonists, such as the GMP-grade synthetic double stranded RNA, poly[I]:poly[C12U] (Ampligen) which is a TLR-3 agonist. Here, we describe the development of a method suitable for the preparation of GMP-grade exosomes from the ascites fluid of ovarian cancer patients, and the methods used for the molecular and immunological characterisation of these exosomes preceding their use in a clinical trial.

    Objective:To assess the role of Th9 and Th17 cells in malignant ascites (MA). Methods: MA from 30 hepatic carcinoma patients and benign ascites from 30 cirrhotic patients were collected. Corresponding peripheral blood samples from these hepatic carcinoma and cirrhotic patients as well as 30 healthy subjects were collected. The frequency of Th9 and Th17 cells was tested by flow cytometry. Serum levels of interleukin (IL)-9 and IL-17 were examined byELISA. Results: The observed frequency of Th9 and Th17 cells, and the IL-9 and IL-17 serum levels were significantly higher in MA patients than those in cirrhotic patients and healthy control samples (P Conclusions:The increased frequency of Th9 and Th17 cells in MA patients suggests that these two T cell subsets play a synergistic role in MA pathogenesis. This study also demonstrated that Th9 and Th17 cells may perform their biological functions in conjunction with IL-9 production.

  19. Inhibition of oxidative phosphorylation in ascites tumor mitochondria and cells by intramitochondrial Ca2+.

    Villalobo, A; Lehninger, A L

    1980-03-25

    Accumulation of Ca2+ (+ phosphate) by respiring mitochondria from Ehrlich ascites or AS30-D hepatoma tumor cells inhibits subsequent phosphorylating respiration in response to ADP. The respiratory chain is still functional since a proton-conducting uncoupler produces a normal stimulation of electron transport. The inhibition of phosphorylating respiration is caused by intramitochondrial Ca2+ (+ phosphate). ATP + Mg2+ together, but not singly, prevents the inhibitory action of Ca2+. Neither AMP, GTP, GDP, nor any other nucleoside 5'-triphosphate or 5'-diphosphate could replace ATP in this effect. Phosphorylating respiration on NAD(NADP)-linked substrates was much more susceptible to the inhibitory effect of intramitochondrial Ca2+ than succinate-linked respiration. Significant inhibition of oxidative phosphorylation is given by the endogenous Ca2+ present in freshly isolated tumor mitochondria. The phosphorylating respiration of permeabilized Ehrlich ascites tumor cells is also inhibited by Ca2+ accumulated by the mitochondria in situ. Possible causes of the Ca2+-induced inhibition of oxidative phosphorylation are considered. PMID:6766937

    Initial rate measurements of the stoichiometric relationships between H+ ejection, K+ and Ca2+ uptake, and electron transport were carried out on mitochondria from Ehrlich ascites tumor cells grown in mice. With succinate as substrate and N-ethylmaleimide to prevent interfering H+ reuptake via the phosphate carrier, close to 8 H+ were ejected per oxygen atom reduced (H+/O ejection ratio = 8.0); with the NAD-linked substrates pyruvate or pyruvate + malate, the H+/O ejection ratio was close to 12. The average H+/site ratio (H+ ejected/2e-/energy-conserving site) was thus close to 4. The simultaneous uptake of charge-compensating cations, either K+ (in the presence of valinomycin) or Ca2+, was also measured, yielding average K+/site uptake ratios of very close to 4 and Ca2+/site ratios close to 2. It was also demonstrated that each calcium ion enters the respiring tumor mitochondria carrying two positive electric charges. These stoichiometric data observed in mitochondria from Ehrlich ascites tumor cells thus are in complete agreement with similar data on normal rat liver and rat heart mitochondria and suggest that the H+/site ratio of mitochondrial electron transport may be 4 generally. It was also observed that the rate of deltaH+ back-decay in anaerobic tumor mitochondria following oxygen pulses is some 6- to 8-fold greater than in rat liver mitochondria tested at equal amounts of mitochondrial protein.

    Full Text Available Ovarian cancer is the most common cause of death from gynecological cancer. Understanding the biology of this disease, particularly how tumor-associated lymphocytes and fibroblasts contribute to the progression and metastasis of the tumor, has been impeded by the lack of a suitable tumor xenograft model. We report a simple and reproducible system in which the tumor and tumor stroma are successfully engrafted into NOD-scid IL2Rγ(null (NSG mice. This is achieved by injecting tumor cell aggregates derived from fresh ovarian tumor biopsy tissues (including tumor cells, and tumor-associated lymphocytes and fibroblasts i.p. into NSG mice. Tumor progression in these mice closely parallels many of the events that are observed in ovarian cancer patients. Tumors establish in the omentum, ovaries, liver, spleen, uterus, and pancreas. Tumor growth is initially very slow and progressive within the peritoneal cavity with an ultimate development of tumor ascites, spontaneous metastasis to the lung, increasing serum and ascites levels of CA125, and the retention of tumor-associated human fibroblasts and lymphocytes that remain functional and responsive to cytokines for prolonged periods. With this model one will be able to determine how fibroblasts and lymphocytes within the tumor microenvironment may contribute to tumor growth and metastasis, and will make it possible to evaluate the efficacy of therapies that are designed to target these cells in the tumor stroma.

    Nanoparticles (NPs) fabricated from the biodegradable copolymer poly(lactic- co-glycolic acid) (PLGA) were investigated as a drug delivery system to enhance the photodynamic efficacy of 5-aminolevulinic acid (5-ALA) in mice bearing Ehrlich ascites carcinoma. The PLGA-encapsulated 5-ALA NPs were prepared using binary organic solvent diffusion method and characterized in terms of shape and particle size. The in vivo photodynamic efficiency in Ehrlich ascites-bearing mice was studied. The obtained particles were uniform in size with spherical shape of mean size of 249.5 nm as obtained by particle size analyzer and the in vitro release studies demonstrated a controlled release profile of 5-ALA. Tumor-bearing mice injected with PLGA-encapsulated 5-ALA NPs exhibited significantly smaller mean tumor volume, increased tumor growth delay compared with the control group and the group injected with free 5-ALA during the time course of the experiment. Histopathological examination of tumor from mice treated with PLGA-encapsulated 5-ALA NPs showed regression of tumor cells, in contrast to those obtained from mice treated with free 5-ALA. The results indicate that PLGA-encapsulated 5-ALA NPs are a successful delivery system for improving photodynamic activity in the target tissue.

    Calcium signaling has been reported to be involved in the pathogenesis of hypertension. Verapamil, one of the calcium antagonists, is used to characterize the role of calcium signaling in the development of pulmonary arterial hypertension syndrome in broilers. The suppression effect of verapamil on pulmonary arterial hypertension and pulmonary vascular remodeling was examined in broilers, from the age of 16 days to 43 days. Our results showed that oral administration of lower dose of verapamil (5 mg/kg body weight every 12 h) prevented the mean pulmonary arterial pressure, the ascites heart index and the erythrocyte packed cell volume of birds at low temperature from increasing, the heart rate from decreasing, and pulmonary arteriole median from thickening, and no pulmonary arteriole remodeling in broilers treated with the two doses of verapamil at low temperature was observed. Our results indicated that calcium signaling was involved in the development of broilers' pulmonary arterial hypertension, which leads to the development of ascites, and we suggest that verapamil may be used as a preventive agent to reduce the occurrence and development of pulmonary arterial hypertension in broilers.

    A 54-year old man with a family history of hyperlipidemia was admitted with a 12 h history of severe generalized abdominal pain associated with nausea, vomiting and abdominal distension. Examination of the abdomen revealed tenderness in the periumblical area with shifting dullness. Serum pancreatic amylase was 29 IU/L and lipase 44 IU/L, triglyceride 36.28 mmol/L. Ultrasound showed ascites. CT of the abdomen with contrast showed inflammatory changes surrounding the pancreas consistent with acute pancreatitis. Ultrasound (US)guided abdomen paracentesis yielded a milky fluid with high triglyceride content consistent with chylous ascites.The patient was kept fasting and intravenous fluid hydration was provided. Meperidine was administered for pain relief. On the following days the patient's condition improved and he was gradually restarted on a low-fat diet, and fat lowering agent (gemfibrozil) was begun,600 mg twice a day. On d 14, abdomen US was repeated and showed fluid free peritoneal cavity. The patient was discharged after 18 d of hospitalization with 600 mg gemfibrozil twice a day. At the time of discharge, the fasting triglyceride was 4.2 mmol/L. After four weeks the patient was seen in the clinic, he was well.

    The synthesis and some of the physical and biological characteristics of a new inhibitor of lactate transport are described. The inhibitor is isobutylcarbonyl lactayl anhydride (iBCLA). It is formed by the condensation of lactic acid and isobutylchloroformate. It inhibits lactate transport 50% at 0.5 microgram/mg of protein in both Ehrlich ascites tumor cells and human erythrocytes. In contrast, 15 microgram of iBCLA/mg of protein is required for 50% inhibition of phosphate transport in erythrocytes, and phosphate transport in Ehrlich ascites tumor cells is unaffected at levels as high as 50 microgram of iBCLA/mg of protein. A time-dependent and concentration-dependent reversal of lactate transport inhibition took place on exposure of iBCLA-treated Ehrlich ascites cells to hydroxylamine or dithiothreitol. These data, along with the observed sensitivity of the lactate transporter to sulfhydryl reagents [Spencer, T. L., & Lehninger, A. L. (1976) Biochem. J. 154, 405-414], suggest that iBCLA acylates an essential sulfhydryl group on the transporter. When glycolyzing Ehrlich ascites tumor cells were treated with concentrations of iBCLA sufficient for complete inhibition of lactate transport, intracellular lactate levels increased, intracellular pH and extra-cellular lactate levels decreased, and overall lactate production was inhibited.

    The present study was designed to compare the anatomical parameters of the cardiopulmonary system in three different lines of chickens with different susceptibility to ascites syndrome. Eggs from three different genetic lines-commercial broiler and layer lines and one native to Iran--were incubated and hatched, and 1-day-old chicks used. The relative heart and lung weights, the volumes of the heart, lung and thorax cavity, the incidence of ascites, and the related physiological parameters in these chickens were followed. Lung weight as a percentage of body weight, the relative lung and heart volume, and the volumes of the thorax cavity, before and after removing heart and lung tissues, were lower in fast-growing broiler chickens compared with the layer and native chickens. Additionally, most of these parameters (e.g. relative lung weight, lung volume and thorax cavity) were significantly decreased with age in broiler chickens but were increased in layer and native chickens, which was concomitant with the incidence of ascites in broiler chickens. Our data indicate that all cardiopulmonary parameters investigated are extremely unfavourable to broiler chickens and suggest a reduction in gas exchange area in broilers, and therefore higher susceptibility to pulmonary hypertension and ascites.

    Full Text Available Summary: Securidaca longepedunculata is a savannah shrub found growing in tropical Africa. It is reputed to have more than a hundred medicinal uses and is a major component of anticancer decoctions in Nigeria. An attempt was made in this study to determine the in vitro and in vivo cytotoxic activity and possible pro-apoptotic effect of Securidaca longepedunculata aqueous root bark extract on Ehrlich ascites carcinoma cells. In vitro cytotoxic activity was determined using the Trypan blue assay by incubating Ehrlich ascites carcinoma cells with various concentrations of Securidaca longepedunculata aqueous extract. In vivo study was carried out by intraperitoneal administration of varied doses of Securidaca longepedunculata to tumour-bearing mice. Isolated DNA from Ehrlich ascites carcinoma cells in treated and untreated animals was used for DNA fragmentation assay on agarose gel. Securidaca longepedunculata Aqueous extract, Securidaca longepedunculata was cytotoxic to Ehrlich ascites both in vivo and in vitro. The IC50 of Securidaca longepedunculata was 67 µg/ml. Securidaca longepedunculata caused a decrease in angiogenesis as observed in the reduction in weight of treated animals and a reduction in volume of ascitic fluid in treated mice.  DNA fragmentation assay of Ehrlich ascites carcinoma cells from treated animals depicted a possible pro-apoptotic effect of the Securidaca longepedunculata extract due to the ladder forming pattern which was comparable to that of the standard drug (fluorouracil. Securidaca longepedunculata aqueous extract had a cytotoxic and pro-apoptotic effect on Ehrlich ascites carcinoma cells. Industrial relevance: The use of Securidaca longepedunculata in traditional medicine in the treatment and management of cancer has been brought to the fore. Development of herbal drugs from the crude extracts could be achieved due to findings suggesting the plant could increase life span in patients with advanced stages of cancer

  10. Percutaneous radiofrequency ablation of hepatocellular carcinoma abutting the diaphragm and gastrointestinal tracts with the use of artificial ascites: safety and technical efficacy in 143 patients

    International Nuclear Information System (INIS)

    The purpose of this study was to assess the feasibility, safety and efficacy of radiofrequency ablation (RFA) with the use of artificial ascites for hepatocellular carcinoma (HCC) adjacent to the diaphragm and gastrointestinal tract. One hundred forty-three patients with 181 HCCs who underwent US-guided percutaneous RFA with the use of artificial ascites were retrospectively reviewed. Among the 181 HCCs, 148 HCCs were defined as problematic nodules for two major reasons: poor sonic window or possible thermal injury. We artificially induced ascites before performing RFA by dripping 5% dextrose in a water solution. We assessed the technical success of introducing artificial ascites, technical feasibility of the use of artificial ascites and complications. The technical success rate, as well as the primary and secondary technique success rate, was assessed by regular follow-up CT examinations. RFA with artificial ascites was successfully achieved in 130 of 143 patients. The primary technique effectiveness was 85.3%. During follow-up (mean, 20.4 months), remote intrahepatic recurrence occurred in 49 patients and local tumor progression occurred in 15 patients. Three (2.1%) of the 143 patients experienced major complications (hemoperitoneum, lobar infarction and biloma) related to the RFA procedure. The use of artificial ascites is a simple and useful technique to minimize collateral thermal injury and to improve the sonic window. (orig.)

  11. Ovarian small cell carcinoma of pulmonary type appearing in ante-mortem ascites: An autopsy case and review of the literature

    Full Text Available Ovarian small cell carcinoma of pulmonary type (OSCCPT is an extremely rare and aggressive disease. The diagnostic significance of cytology of ascites for OSCCPT, however, has not been shown so far. Here, we report the diagnosis of this carcinoma in an autopsy case with ante-mortem cytology of ascites. A 75 year-old woman was detected with bilateral ovarian cancer by radiological imaging. Although operation was planned, massive ascites was discovered a few weeks later. Ascites was removed with abdominocentesis, which cytologically diagnosed presence of carcinoma, suspicious of adenocarcinoma. A few days later, she died. From autopsy samples, we diagnosed this case as bilateral OSCCPT, showing neuroendocrine differentiation by immunohistochemistry. We reviewed ante-mortem cytology of ascites and found scattered small atypical cells. Immunocytochemical study of the cell block of the ascites showed neuroendocrine differentiation of the atypical cells in an identical manner as the autopsy specimens. Since small atypical cells of OSCCPT often exist with other histological tumor components, careful screening of all cells on the preparation is advisable to accurately diagnose OSCCPT by cytology of ascites.

    1986-03-01

    Full Text Available Mice infected with 60 cercariae of Schistosoma mansoni were more resistant to the sarcoma 180 ascites tumor. Tumor inoculation was performed 50 days after schistosoma infection and the animals were observed and weighed at 48 hours intervals for development and progression of malignancy. In infected mice the weight gain (ascites formation started later and was shorter than in uninfected Controls. Also, the number of tumor cells into the peritoneal cavity 72h after tumor implantation was shorter in infected group than incontrols. This in creased resistance against a transplantable tumor probably is related to the effect of endotoxin on tumoricidal activity of macrophages activated by the infection. The immunodepression induced by Schistosoma mansoni infection enhances the proliferation of endogenous bacteria increasing the amount of endotoxin absorbed from the gut.Camundongos infectados com 60 cercárias de Schistosoma mansoni tomaram-se mais resistentes ao sarcoma 180 na forma de tumor ascítico. A inoculação das células tumorais foi feita no 50º dia de infecção e a evolução do tumor foi acompanhada através dapesagem dos animais com intervalos de 48 horas. Nos camundongos infectados o ganho de peso (formação da ascite começou mais tarde e foi menor do que nos controles não infectados. Também o número de células tumorais na cavidade peritoneal 72 horas após a implantação do tumor foi menor no grupo infectado. Este aumento de resistência a um tumor transplantávelpossivelmente está relacionado ao efeito de endotoxinas sobre a atividade tumoricida dos macrofagos ativados pela infecção. A imunossupressão induzida pela infecção favorece a proliferação de bactérias da flora endógena aumentando a quantidade de endotoxinas absorvidas pelo intestino.

    The study was conducted to determine the effects of dietary L-carnitine and coenzyme Q10 (CoQ10) supplementation on growth performance and ascites mortality of broilers. A 3 x 3 factorial arrangement was employed with three levels (0, 75 and 150 mg/kg) of L-carnitine and three levels of CoQ10 (0, 20 and 40 mg/kg) supplementation during the experiment. Five hundred and forty one-day-old Arbor Acre male broiler chicks were randomly allocated into nine groups with six replicates each. All birds were fed with the basal diets from day 1 to 7 and changed to the experimental diets from day 8. During day 15 to 21 all the birds were exposed to low ambient temperature (15-18 degrees C) to induce ascites. The results showed that under this condition, growth performance of broilers were not significantly affected by CoQ10 or L-carnitine + CoQ10 supplementation during week 0-3 and 0-6, but body weight gain (BWG) of broilers was significantly reduced by 150 mg/ kg L-carnitine during week 0-6. Packed cell volume (PCV) of broilers was significantly decreased by L-carnitine and L-carnitine + CoQ10 supplementation (P ascites heart index (AHI) and ascites mortality of broilers were significantly decreased by L-carnitine, CoQ10 and L-carnitine + CoQ10 supplementation. Though no significant changes were observed in total antioxidative capability (T-AOC), total superoxide dismutase (T-SOD) was increased by L-carnitine, CoQ10 and L-carnitine + CoQ10 supplementation (P ascites mortality of broilers; the reason may be partially associated with their antioxidative effects.

  15. Clinical value of detection of malignant ascites and thoracic exudate by means of six tumor-markers

    International Nuclear Information System (INIS)

    Objective: To study the clinical value of six potential tumor markers including serums CA125, CYFRA21-1, CA-50, CA15-3, HCG, β-HCG. These were determined in effusions of malignant ascites and hydrothorax of 170 patients, with cellular examination as control. Methods: Using IRMA. Results: The data of our experiments revealed that of all six tumor-markers, CA125 was the highest in positive rate as well as concordance rate with cytology examination. In or- der CA125, CA-50, CA15-3, CYFRA21-1, β-HCG. It was valuable to point out that the specificity of HCG and β-HCG was very strong and there was no false positivity had yet been found with them. Though their positivity was not so high as that of CA125. Have to higher specificity of detection of malignant ascites by CYFRA21-1. Conclusions: It suggested that + CYFRA21-1 should be the preferred choice in diagnosing malignant hydrothorax next + CA-50,CYFRA21-1 +CA-50; for malignant ascites as well, CA125 + β-HCG determination is just as good, next CA125 + CYFRA21-1. We believe that when a clear diagnosis of a primary focus of cancer is made clinically, or a malignant ascites or thoracic exudate come highly under suspicion, the diagnosis of malignancy of the ascites or thoracic exudate can be established even though the exfoliative cells, provided the detection by tumor-markers, it has got one of the following results: the roles of tumor-markers determination in malignant serous effusions, two of CA125, CYFRA21-1. CA15-3 and CA-50 markers are positive; anyone of the above markers plus HCG or β-HCG positivity; both HCG and β-HCG or CA15-3 are positive. (author)

    Results concerning 14 cirrhotic patients who underwent LeVeen peritoneo-venous shunt for refractory or complicated ascites are discussed. The most relevant early complications regard coagulation disorders (35.7%) with a 14.3% postoperative mortality. The functional result appears largely satisfactory, also in terms of long-term efficiency. Utility of a wide evacuation of ascitic fluid during the operation is underlined. Ascites drainage at operation doesn't compromise shunt function or renal resumption, furthermore it may prevent some life-threatening complications like DIC, esophageal varices rupture and congestive heart failure.

    in miRNA expression in a sensitive and five increasingly drug-resistant Ehrlich ascites tumor (EAT) cell lines, representing different steps in the development of resistance. We used an LNA-enhanced microarray platform to study the global miRNA expression profiles in the six murine EAT cell lines...... clusters miR-30d∼miR-30b and miR-23b∼miR-27b∼miR-24-1 were downregulated in most of the resistant EAT cells. Several of the target genes for these miRNAs-including Zeb1/Zeb2 and members of the Fox gene family-could contribute to the drug-resistant phenotype, although we did not find that the degree of...

  18. Regulation of Caspase-3 and Bcl-2 Expression in Dalton's Lymphoma Ascites Cells by Abrin

    Directory of Open Access Journals (Sweden)

    V. Ramnath

    2009-01-01

    Full Text Available The role of abrin, a toxic lectin isolated from seeds of Abrus precatorius Linn in inducing apoptosis in murine Dalton's Lymphoma Ascites (DLA cells was evaluated. Abrin when incubated at the concentration of 10 ng per million DLA cells could bring about cell death as typical morphological changes with apoptosis. However, necrotic cell death dominated when a higher dose of abrin was used. DNA samples, isolated from DLA cells treated with abrin showed fragmentation. Abrin brought about induction of apoptosis by stimulating the expression of pro-apoptotic Caspase-3, at the same time blocking the expression of Bcl-2, which is an anti apoptotic gene. However, the expression of tumor suppressor gene p53 has not been observed in control and abrin-treated DLA cells. Results suggested that abrin effectively induced apoptotic changes in the tumor cells that led to cellular death.

    Protein phosphorylation/dephosphorylation and cytoskeletal reorganization regulate the Na(+)-K(+)-2Cl(-) cotransporter (NKCC1) during osmotic shrinkage; however, the mechanisms involved are unclear. We show that in cytoplasts, plasma membrane vesicles detached from Ehrlich ascites tumor cells (EATC......) by cytochalasin treatment, NKCC1 activity evaluated as bumetanide-sensitive (86)Rb influx was increased compared with the basal level in intact cells yet could not be further increased by osmotic shrinkage. Accordingly, cytoplasts exhibited no regulatory volume increase after shrinkage. In cytoplasts......, cortical F-actin organization was disrupted, and myosin II, which in shrunken EATC translocates to the cortical region, was absent. Moreover, NKCC1 activity was essentially insensitive to the myosin light chain kinase (MLCK) inhibitor ML-7, a potent blocker of shrinkage-induced NKCC1 activity in intact...

    About 5% of patients with chronic liver disease develop massive refractory ascites. These patients cease to respond to diuretic therapy and may develop prerenal azotemia. There is a small but definite role for the peritoneo-venous shunt in these patients. In our study of 36 patients, managed with locally made, single-valved peritoneo-venous shunts (GSAIMS shunts), shunt failure and complication rates were assessed postoperatively. There is a definite improvement in quality of life with this cost-effective locally made shunt if patients are selected carefully. Long-term follow-up of these patients is not possible because most of these patients succumb to advanced liver disease. PMID:15285240

  1. Surface markers of small lymphocytes appearing in the mouse Ehrlich ascites tumour, host spleen and blood

    International Nuclear Information System (INIS)

    Small lymphocytes sampled from intraperitoneally growing Ehrlich ascites tumour in CBA/H-T6 mice as well as host spleen and blood at different days of tumour development were characterized radioautographically on the basis of two surface markers, IgM for B cells and theta antigen for T cells. A direct binding of 125I-labelled anti-IgM detected natural surface IgM, while an indirect binding following a prior exposure to anti-theta antibody detected theta antigen. Cells remaining unlabelled with the latter procedure were considered to lack both markers (double negative). Changes in the proportions and absolute numbers of the different cells were related to tumour growth and development. (author)

    Eighty % of ovarian cancer patients diagnosed at an advanced-stage have complete remission after initial surgery and chemotherapy. However, most patients die within identification of 353 proteins. There were significant differences in proteins encoding for immune surveillance, DNA repair mechanisms, cytoskeleton rearrangement, cell-cell adhesion, cell cycle pathways, cellular transport, and proteins involved with glycine/proline/arginine synthesis in tumor cells isolated from CR relative to CN patients. Pathway analyses revealed enrichment of metabolic pathways, DNA repair mechanisms and energy metabolism pathways in CR tumor cells. In conclusion, this is the first proteomics study to comprehensively analyze ascites-derived tumor cells from CN and CR ovarian cancer patients. PMID:27470985

    The taurine efflux from Ehrlich ascites tumor cells is stimulated by hypotonic cell swelling. The swelling-activated taurine efflux is unaffected by substitution of gluconate for extracellular Cl– but inhibited by addition of MK196 (anion channel blocker) and 4,4 -diisothiocyanostilbene-2......,2 -disulfonic acid (DIDS; anion channel and anion exchange blocker) and by depolarization of the cell membrane. This is taken to indicate that taurine does not leave the osmotically swollen Ehrlich cells in exchange for extracellular Cl–, i.e., via the anion exchanger but via a MK196- and DIDS-sensitive channel...... that is potential dependent. An additional stimulation of the swelling-activated taurine efflux is seen after addition of arachidonic acid and oleic acid. Cell swelling also activates a Mini Cl– channel. The Cl– efflux via this Cl– channel, in contrast to the swelling-activated taurine efflux, is...

    The antitumour activities of extracts from the Red Sea seaweeds Jania rubens, Sargassum subrepandum, and Ulva lactuca were investigated in an in vivo mice model based on intramuscular injection of Ehrlich ascites tumour cells. In parallel, antioxidant activities were measured. Tumour marker levels, liver biochemical parameters, and hepatic oxidant/antioxidant status were measured to prove the anticancer and antioxidant nature of the algal extracts. Significant decreases in carcinoembryonic antigen (CEA) and a-fetoprotein (AFP) levels, activities of liver enzymes, levels of nitric oxide (NO) and malondialdehyde (MDA), and an increase in total antioxidant capacity (TAC) were recorded in groups treated with the algal extracts. Jania rubens was selected for phytochemical screening of its phytoconstituents. In addition, carotenoids, halides, minerals, lipoidal matters, proteins, and carbohydrates were studied. Furthermore, 7-oxo-cholest-5(6)-en-3-ol (1) and cholesterol (2) were isolated from the dichloromethane fraction. PMID:21950161

    A 60-year-old woman without a history of liver diseases, but with a history of regular alcohol consumption, presented with a right-sided transudative pleural effusion. Neither parenchymal lung lesion nor pleural thickening was seen on a chest computed tomography. On abdominal ultrasonography, the liver size and contour were normal, and ascites was not noted. Despite performing imaging and laboratory studies, we could not find a cause of the pleural effusion. Thus, due to her history of regular alcohol consumption, we decided to measure liver stiffness using a transient elastography (Fibroscan(®), Echosens(TM), Paris, France), which showed a value of 35.3 kPa suggestive of liver cirrhosis. An intraperitoneal injection of a radioisotope demonstrated the transdiaphragmatic flow of fluid from peritoneal cavity to pleural cavity. The diagnosis was confirmed as hepatic hydrothorax. Management consisting of restricted salt and water intake with diuretics resulted in resolution of the hepatic hydrothorax. PMID:26839695

    Ehrlich ascites tumor cells! loaded with H-labeled arachidonic acid and C-labeled stearic acid for two hours, were washed and transferred to either isotonic or hypotonic media containing BSA to scavenge the labeled fatty acids released from the cells. During the first two minutes of hypo......-osmotic exposure the rate of H-labeled arachidonic acid release is 3.3 times higher than that observed at normal osmolality. Cell swelling also causes an increase in the production of C-stearic acid-labeled lysophosphatidylcholine. This indicates that a phospholipase A is activated by cell swelling in the Ehrlich...... cells. Within the same time frame there is no swelling-induced increase in C-labeled stearic acid release nor in the synthesis of phosphatidyl C-butanol in the presence of C-butanol. Furthermore, U7312, an inhibitor of phospholipase C, does not affect the swelling induced release of C...

  9. Effects of intratumoral injection of I-125 iododeoxyuridine on Ehrlich ascites carcinoma

    International Nuclear Information System (INIS)

    Intratumoral injection of I-125 iododeoxyuridine (IUdR), saline solution, and oil suspension was investigated using Ehrlich ascites tumors in the thighs of mice. The oil suspension was more effective in tumor growth delay than was the saline solution. Single injection of the oil suspension at the dose of 12.5 microCi resulted in 21.5 days growth delay, whereas 50 microCi of the saline solution resulted in 11.5 days growth delay relative to control growth delay. At 40 days after treatment, higher radioactivities were observed in the tumor and the skin of the mice treated with the oil suspension, which represented the prolongation of I-125 IUdR oil suspension within the tumor. No normal tissue toxicities were observed

    1. Blood oxygen saturation (SaO) is a potential indicator trait for resistance to ascites in chickens. 2. The objective of the study was to investigate the genetic architecture of SaO in a meat-type chicken line reared in commercial conditions. 3. Data were collected over 15 generations of selection and were divided into two data sets on the basis of a change in recording age from 6 to 5 weeks of age, approximately halfway through the period. The resulting pedigrees comprised in excess of 90,000 birds each and, on average, 12% of these birds had SaO records. 4. Segregation analyses of SaO were carried out assuming a mixed inheritance model that included a major locus segregating in a polygenic background. 5. The analyses suggest that a major gene is involved in the genetic control of SaO in this line. The putative gene acts in a dominant fashion and has an additive effect of around 0.90 sigma(p), equivalent to a predicted difference in SaO between the two homozygous classes of more than 10%. The frequency of the allele that increases SaO changed from 0.53 to 0.65 from the first to the second set of data, consistent with selection on SaO scores. 6. Using estimated genotype probabilities at the putative major locus, we inferred that it acts in an overdominant fashion on body weight and fleshing score. If the low SaO allele leads to susceptibility to ascites, its combined effects are consistent with it being maintained in the population by a balance of natural selection on fitness nad artificial selection on growth and carcase traits. 7. Even with selection on both SaO and growth traits, the combined genotypic effects would make it difficult to remove the unfavourable low-SaO allele by means of traditional selection without the use of genetic markers.

    Full Text Available Objective To evaluate the efficacy and safety of selective vasopressin V2 receptor antagonists in the treatment of hepatic cirrhosis patients with ascites. Methods PubMed, EMBASE, Web of Science, The Cochrane Central Register of Controlled Trials, Database for Chinese Technical Periodical (VIP, Chinese Journal Full-Text Database (CNKI, and Wan Fang Digital Journal Full-text Database were retrieved to collect clinical randomized controlled trials of hepatic cirrhosis with ascites treated by selective vasopressin V2 receptor antagonists. Meta analysis was performed by using Review Manager 5.0. Results Nine randomized controlled trials including 1884 patients met the inclusion criteria. Meta-analysis showed that: 1 The selective vasopressin V2 receptor antagonists were associated with a significant reduction in body weight compared with placebo (WMD=–1.98kg, 95%CI:–3.24-–0.72kg, P=0.002. Treatment with selective vasopressin V2 receptor antagonists was associated with an improvement of low serum sodium concentration compared to placebo (WMD=3.74mmol/L, 95%CI: 0.91-6.58mmol/L, P=0.01. The percentage of patients with worsening ascites was higher in the group of patients treated with placebo (RR=0.51, 95%CI: 0.34-0.77, P=0.001. 2 The amplitude of increased urine volume was obviously higher in selective vasopressin V2 receptor antagonists group than in placebo group (WMD=1437.65ml, 95%CI: 649.01-2226.30ml, P=0.0004.

    Malignant ascites (MA) is most commonly observed in patients scheduled for epithelial ovarian cancer (EOC) surgery and is supposed as a major risk factor promoting perioperative hemodynamic deterioration. We aimed to assess the hemodynamic consequences of MA on systemic circulation in patients undergoing cytoreductive EOC surgery.This study is a predefined post-hoc analysis of a randomized controlled pilot trial comparing intravenous solutions within a goal-directed algorithm to optimize hemodynamic therapy in patients undergoing cytoreductive EOC surgery. Ascites was used to stratify the EOC patients prior to randomization in the main study. We analyzed 2 groups according to the amount of ascites (NLAS: none or low ascites [500 mL]). Differences in hemodynamic variables with respect to time were analyzed using nonparametric analysis for longitudinal data and multivariate generalized estimating equation adjusting the analysis for the randomized study groups of the main study.A total of 31 patients in the NLAS and 16 patients in the HAS group were analyzed. Although cardiac output was not different between groups suggesting a similar circulatory blood flow, the HAS group revealed higher heart rates and lower stroke volumes during surgery. There were no differences in pressure-based hemodynamic variables. In the HAS group, fluid demands, reflected by the time to reindication of a fluid challenge after preload optimization, increased steadily, whereas stroke volume could not be maintained at baseline resulting in hemodynamic instability after 1.5 h of surgery. In contrast, in the NLAS group fluid demands were stable and stroke volume could be maintained during surgery. Clinically relevant associations of the type of fluid replacement with hemodynamic consequences were particularly observed in the HAS group, in which transfusion of fresh frozen plasma (FFP) was associated to an improved circulatory flow and reduced vasopressor and fluid demands, whereas the

    The development of ascites was investigated in broilers at low versus high altitudes, cold versus normal ambient temperatures (AT), and 3 feeding regimens. One-day-old chicks obtained at sea level were reared at high altitude (highA; 1,720 m; n = 576) with 2 AT treatments, low AT from 3 wk onward at highA (highA/cold) and normal AT from 3 wk onward at highA (highA/norm), or at sea level (normal AT from 3 wk onward at low altitude, lowA/norm; n = 540). Under highA/cold, AT ranged between 16 to 17 degrees C in the fourth week, 17 to 19 degrees C in the fifth week, and 19 to 21 degrees C thereafter. Under highA/norm and lowA/norm, AT was 24 degrees C in the fourth week and ranged between 22 to 24 degrees C thereafter. Broilers in each condition were divided into 3 groups: feed restriction (FR) from 7 to 14 d, FR from 7 to 21 d, and ad libitum (AL). Ascites mortality and related parameters were recorded. Low mortality (0.4%) occurred under lowA/norm conditions. Under highA/norm, mortality was lower in females (8.6%) than in males (13.8%) and was not affected by the feeding regimen. The highA/cold treatment resulted in higher mortality but only in males; it was 44.2% among highA/cold AL-fed males and only about 26% under the FR regimens, suggesting that FR helped some males to better acclimatize to the highA/cold environment and avoid ascites. However, mortality was only 13.3% in AL-fed males at highA/norm and FR did not further reduce the incidence of ascites under these conditions. Thus, avoiding low AT in the poultry house by slight heating was more effective than FR in reducing ascites mortality at highA. Compared with FR from 7 to 14 d, FR from 7 to 21 d did not further reduce mortality and reduced growth. At 47 d, the majority of surviving broilers at highA had high levels of hematocrit and right ventricle:total ventricle weight ratio (>0.29), but they were healthy and reached approximately the same BW as their counterparts at low altitude. This finding may

After intraperitoneal administration of the nanotargeted bimodality 188Re-DXR-liposome, the ascites and tumor accumulation of the radioactivity were observed, the levels of radioactivity within the ascites were maintained at relatively higher levels before 48 h and the levels of radioactivity in the tumor were maintained at steady levels after 4 h. The AUC(o→∞) of 188Re-DXR-liposome in blood, ascites and tumor was 9.3-, 4.2- and 4.7-fold larger than that of 188Re-BMEDA, respectively. The maximum tolerated dose of intraperitoneally administrated 188Re-DXR-liposome was determined in normal BALB/c mice. The survival, tumor and ascites inhibition of mice after 188Re-DXR-liposome (22.2 MBq of 188Re, 5 mg/kg of DXR) treatment were evaluated. Consequently, radiochemotherapeutics of 188Re-DXR-liposome attained better survival time, tumor and ascites inhibition (decreased by 49% and 91% at 4 days after treatment; P188Re-liposome or chemotherapeutics of Lipo-Dox did.

    The congenital dyserythropoietic anemias comprise a group of rare hereditary disorders of erythropoiesis,characterized by ineffective erythropoiesis as the predominant mechanism of anemia and by characteristic morphological aberrations of the majority of erythroblasts in the bone marrow. Congenital dyserythropoietic anemia type Ⅱ is the most frequent type. All types of congenital dyserythropoietic anemias distinctly share a high incidence of iron loading. Iron accumulation occurs even in untransfused patients and can result in heart failure and liver cirrhosis. We have reported about a patient who presented with liver cirrhosis and intractable ascites caused by congenital dyserythropoietic anemia type Ⅱ. Her clinical course was further complicated by the development of autoimmune hemolytic anemia. Splenectomy was eventually performed which achieved complete resolution of ascites, increase of hemoglobin concentration and abrogation of transfusion requirements.

    Full Text Available Abstract Background In ovarian cancer, massive intraperitoneal dissemination is due to exfoliated tumor cells in ascites. Tumor-initiating cells (TICs or cancer stem cells and cells showing epithelial-mesenchymal-transition (EMT are particularly implicated. Spontaneous spherical cell aggregates are sometimes observed, but although similar to those formed by TICs in vitro, their significance is unclear. Methods Cells freshly isolated from malignant ascites were separated into sphere samples (S-type samples, n=9 and monolayer-forming single-cell suspensions (M-type, n=18. Using western blot, these were then compared for expression of protein markers of EMT, TIC, and of cancer-associated fibroblasts (CAFs. Results S-type cells differed significantly from M-type by expressing high levels of E-cadherin and no or little vimentin, integrin-β3 or stem cell transcription factor Oct-4A. By contrast, M-type samples were enriched for CD44, Oct-4A and for CAF markers. Independently of M- and S-type, there was a strong correlation between TIC markers Nanog and EpCAM. The CAF marker α-SMA correlated with clinical stage IV. This is the first report on CAF markers in malignant ascites and on SUMOylation of Oct-4A in ovarian cancer. Conclusions In addition to demonstrating potentially high levels of TICs in ascites, the results suggest that the S-type population is the less tumorigenic one. Nanoghigh/EpCAMhigh samples represent a TIC subset which may be either M- or S-type, and which is separate from the CD44high/Oct-4Ahigh subset observed only in M-type samples. This demonstrates a heterogeneity in TIC populations in vivo which has practical implications for TIC isolation based on cell sorting. The biological heterogeneity will need to be addressed in future therapeutical strategies.

    Three experiments were conducted, from January until September 2001, to estimate the optimized age to apply feed restriction to control mortality from ascites, with no negative effects on production and carcass characteristics of broilers. For each experiment, 1,200 1-d-old mixed Ross x Peterson chicks were reared in floor pens (50 chicks in each) and fed commercial feed. Feed restriction was applied for 8 h/d for 14 d at 21 or 28 d of age in experiment 1, 14 or 21 d in experiment 2, and 7 or 14 d in experiment 3. In experiments 2 and 3, a microelement supplement (without or with) was tested; the control groups received feed ad libitum and no supplement. Body weight gain, feed conversion, total mortality, and mortality from ascites, leg problems, and carcass characteristics were considered at the end of each experiment. The data were analyzed as a completely randomized design, or as a 2 x 2 factorial to estimate main and interaction effects (experiments 2 and 3). Additional analyses, including the control, were done; means comparisons were by orthogonal contrasts. The production and carcass characteristics of the restricted groups were lower than the control but were not statistically different in experiments 2 and 3, although the optimized age for feed restriction was at 7 d. Total mortality and mortality from ascites decreased by restriction, but leg problems increased without supplement. The results indicated that quantitative feed restriction and microelement supplementation at 7 d of age reduced mortality from ascites and leg problems and permitted compensatory growth sufficient to equal the production characteristics of the control group at 49 d of age. However, it is necessary to determine the specific microelements to be supplemented and to estimate the effects of season and genetic line. PMID:15109050

    Ascites syndrome, also known as pulmonary hypertension syndrome (PHS), is a common metabolic disorder in rapidly growing meat-type chickens. Environmental factors, such as cold, altitude, and diet, play significant roles in development of the disease, but there is also an important genetic component to PHS susceptibility. The human disease familial primary pulmonary hypertension (FPPH) is similar to PHS in broilers both genetically and physiologically. Several recent studies have shown that mutations in the bone morphogenetic protein receptor type II (BMPR2) gene are a cause of FPPH in humans. To determine whether mutations in the chicken BMPR2 gene play a similar role in PHS susceptibility, BMPR-II mRNA from ascitic and nonascitic commercial broilers were sequenced and compared with the published Leghorn chicken BMPR-II mRNA sequence. Fourteen single nucleotide polymorphisms (SNP) were identified in the commercial broiler BMPR-II mRNA. No mutations unique to ascites-susceptible broilers were present in the coding, 5' untranslated or 3' untranslated regions of BMPR-II mRNA. The twelve SNP present within the coding region of BMPR-II mRNA were synonymous substitutions and did not alter the BMPR-II protein sequence. In addition, analysis of BMPR2 gene expression by reverse transcriptase-PCR indicated that there were no differences in BMPR-II mRNA levels in ascitic and nonascitic birds. Therefore, it appears unlikely that mutations in the BMPR2 gene were responsible for susceptibility to PHS in these commercial broilers. PMID:14601724

  13. Segregation among test-cross progeny suggests that two complementary dominant genes explain the difference between ascites-resistant and ascites-susceptible broiler lines.

    Ascites syndrome (AS) is a major cause of economic losses to the broiler industry. The tendency of broilers to develop AS was found to be heritable, suggesting that selective breeding could provide a solution to this problem. To further elucidate the genetic control of AS, AS-susceptible (AS-S) and AS-resistant (AS-R) lines were established by 3 cycles of divergent selection on pedigree data of AS mortality under AS-inducing conditions. The rapid divergence between the lines suggested the involvement of a major gene with dominance for AS resistance. It was hypothesized that the difference between the lines is controlled by a single dominant gene, denoted A, with AA (and some Aa) individuals in the AS-R line, and aa individuals in the AS-S line. The current study was designed to test this hypothesis by test-crossing heterozygous (Aa) sires from the AS-R line and F(1) from the AS-R x AS-S cross, with recessive homozygous (aa) dams from the AS-S line. A ratio of 1:1 was expected between progeny with AS vs. healthy progeny when reared under AS-inducing conditions. Test-cross progeny of 5 sires from the AS-R line segregated 1:1, indicating that these sires were heterozygous (Aa) in the suggested major gene and thus supporting the hypothesis of a single major gene with dominance of AS resistance. There was segregation among test-cross progeny of 8 F(1) sires, but with a 3:1 ratio of AS progeny to healthy progeny. The 3:1 ratio is expected if the F(1) sires are heterozygous (AaBb) with complementary interaction between the dominant alleles in 2 unlinked major genes. The segregation among test-cross progeny of the 9 heterozygous AS-R sires could also be explained by the same model. These results suggested that 2 major genes are responsible for the difference between the AS-R and AS-S lines. Resource populations derived from these lines will facilitate an efficient genomic search for these 2 genes. Once the alleles of these genes are identified and genotyping tests are

    Full Text Available Although spleen stiffness has recently been identified as potential surrogate marker for portal hypertension, the relationship between spleen stiffness and portal hypertension has not been fully elucidated. We attempted to determine the relationship between the liver or spleen stiffness and the presence of ascites or esophageal varices by acoustic radiation force impulse (ARFI imaging. A total of 33 chronic hepatitis C (CHC patients (median age 68; range 51–84 were enrolled. We evaluated the relationship between the liver or spleen stiffness and indicators of portal hypertension as well as clinical and biochemical parameters. Fourteen healthy volunteers were used for validating the accuracy of AFRI imaging. The liver and spleen stiffness increased significantly with progression of liver disease. A significant positive correlation was observed between the liver and spleen stiffness. However, spleen stiffness, but not liver stiffness, was significantly associated with the presence of ascites (, while there was no significant association between the spleen stiffness and spleen index/presence of esophageal varices in CHC patients. The area under the receiver operating characteristic curve based on the spleen stiffness was 0.80. In conclusion, spleen stiffness significantly correlates with the presence of ascites but not esophageal varices in CHC patients.

These patients had no other procedures and survived more than 5 years after the operation. All patients were free of ascites except one in whom it was mild. One patient refused follow-up. Shunt patency was assessed in 23 patients. In 14 patients (60.9%), the shunt was obstructed and the superior vena cava was occluded in 5 of them. In 9 patients (39.1%), the shunt was still functioning. No clinical or biological parameters differentiated these two groups of patients. Of the 24 patients who were alcoholics, 2 abstained completely and 20 significantly reduced their drinking habits. In 25 patients, the Pugh's score improved and was A at the time of the study. Seven patients (25.9%) developed a malignant tumor of the oro-pharynx or digestive tract, all other patients were alive and in good health. This study suggests that patients with intractable ascites treated by a peritoneo-venous shunt may survive for a long period. In patients abstaining from heavy drinking, it may function as a therapeutic bridge permitting spontaneous improvement of liver function. The risk of supervening neoplasms suggests that a continuous follow-up of these patients is warranted. PMID:2487384

  16. Effect of chloro- and bromo-derivatives of isocrotonic acid on bioenergetic processes in Ehrlich ascites cells and isolated mitochondria

    International Nuclear Information System (INIS)

    The effect of nine chloro- and bromoderivatives of isocrotonic acid on some bioenergetic processes in both Ehrlich ascites cells and isolated rat liver mitochondria has been investigated. Substances studied in the concentration range 25 to 200 μM significantly inhibited incorporation of both 14C-adenine and 14C-valine into acid-insoluble material of Ehrlich ascites cells. The rate of 14C-precursors incorporation being directly related to the concentration of the inhibitor. γ,γ-bis-4-ethylphenyl-α,β-dichloroisocrotonic acid fully inhibits both aerobic glucose utilization and lactic acid formation at 200 μM concentration. At lower concentrations, however, glycolysis is stimulated. Maximal stimulation of rat liver mitochondrial respiration in state 4 with succinate as substrate was reached at concentrations as low as 10 μM. On the other hand, these substances were able to release the oligomycin-inhibited respiration of rat liver mitochondria. Our data suggest that cytotoxic and cancerostatic action of isocrotonic acid derivatives lies primarily in the exclusion of key processes in the energy metabolism of Ehrlich ascites cells and isolated mitochondria.

  17. The Interstitial Lymphatic Peritoneal Mesothelium Axis in Portal Hypertensive Ascites: When in Danger, Go Back to the Sea

    Full Text Available Portal hypertension induces a splanchnic and systemic low-grade inflammatory response that could induce the expression of three phenotypes, named ischemia-reperfusion, leukocytic, and angiogenic phenotypes.During the splanchnic expression of these phenotypes, interstitial edema, increased lymph flow, and lymphangiogenesis are produced in the gastrointestinal tract. Associated liver disease increases intestinal bacterial translocation, splanchnic lymph flow, and induces ascites and hepatorenal syndrome. Extrahepatic cholestasis in the rat allows to study the worsening of the portal hypertensive syndrome when associated with chronic liver disease. The splanchnic interstitium, the mesenteric lymphatics, and the peritoneal mesothelium seem to create an inflammatory pathway that could have a key pathophysiological relevance in the production of the portal hypertension syndrome complications. The hypothetical comparison between the ascitic and the amniotic fluids allows for translational investigation. From a phylogenetic point of view, the ancestral mechanisms for amniotic fluid production were essential for animal survival out of the aquatic environment. However, their hypothetical appearance in the cirrhotic patient is considered pathological since ultimately they lead to ascites development. But, the adult human being would take advantage of the potential beneficial effects of this “amniotic-like fluid” to manage the interstitial fluids without adverse effects when chronic liver disease aggravates.

    Background Patients with cirrhotic ascites (PCA) are susceptible to spontaneous bacterial peritonitis (SBP) which has increased morbidity and mortality. Since some host defense aspects of peritoneal macrophages (PMф) from PCA are altered this study examined factors related to receptor-mediated phagocytosis. Methods Twelve PCA were studied. PMɸ were isolated from ascitic fluid (AF) samples removed from these patients. Uptake of mannose receptor (MR)-specific ligand, fluorescein isothiocyanate-mannosylated-bovine serum albumin (FITC-man-BSA), by patients' PMɸ and controls, a human monocytic cell line, was measured pre- and post-IL-4 treatment. Phagocytosis of FITC-labeled yeast particles by patients' PMɸ was measured pre- and post-IL-4 treatment. Fluorescence values were obtained using a spectrofuorometer. MRC1 gene was analyzed in blood samples from PCA and controls, healthy donors, using standard polymerase chain reaction (PCR) technique. Results Past SBP episode(s) were reported in 58.3% of patients. Mean AF volume analyzed per patient was 1.3L. PMɸ ratio in cell yield was 53.73% (SD 18.1). Mean uptake absorbance of patients' PMф was 0.0841 (SD 0.077) compared to 0.338 (SD 0.34) of controls, P = 0.023. Following IL-4 treatment absorbance increased to 0.297 (SD 0.28) in patients' PMф (P = 0.018 on paired sample t-test), and to 0.532 (SD 0.398 in controls (P = 0.053 on independent sample t-test). Mean phagocytosis absorbance of patients' PMф was 0.1250 (SD 0.032) before IL-4 treatment compared to 0.2300 (SD 0.104) after (P = 0.026). PCR analysis for MRC1 gene was negative in all PCA samples compared to positive results in all controls. Conclusion Since decreased phagocytosis and MR uptake were enhanced post-IL-4 treatment MR downregulation pre-treatment is plausible. Negative PCR results for MRC1 might suggest an anomaly, but this awaits further ellucidation. These altered host defense findings are relevant to infection pathophysiology, and their

    Ascites syndrome (AS) is manifested in flocks of contemporary broilers that are allowed to fully manifest their genetic potential for rapid growth. After successful selection, a pair of divergent lines was established, AS-susceptible (AS-S) and AS-resistant (AS-R). These lines facilitate comparisons between genetically resistant and susceptible healthy young broilers when reared under standard brooding conditions (SBC). The aim of the present study was to look for predictive indicators for AS susceptibility by comparing relevant physiological parameters in the AS-S and AS-R lines under SBC and after exposure to extreme ascites-inducing conditions (AIC). In this design, a trait differing significantly between the 2 lines under SBC is expected to be a reliable indicator for selection against AS susceptibility in breeding stocks when reared under noninducing conditions. Males from the AS-S and AS-R lines were reared together under SBC to 19 d of age, then under the AIC protocol. Cumulative incidence of AS mortality was 93.2% in the AS-S line and only 9% in the AS-R line, confirming the genetic divergence between the lines. Exposure to AIC enhanced the imbalance between oxygen demands and supply in the AS-S birds and induced differences in blood parameter level between the 2 lines. The AS-S birds exhibited elevated hematocrit and red blood cell counts and a decline in oxygen saturation in the arterial blood. No difference in hemoglobin concentration was found, but calculation of hemoglobin content per 1,000 red blood cells revealed a significant reduction in hemoglobin content in the AS-S birds. Under SBC, there were no significant differences between the lines for hematocrit, red blood cell count, hemoglobin concentration, hemoglobin count per 1,000 red cells, and blood oxygen saturation. However, heart rate during the first week of life was significantly higher in the AS-S birds than in the AS-R birds on d 1 and 7, suggesting that high heart rate may potentially

    Thioredoxin reductase (TrxR) is a target for cancer therapy and the anticancer mechanism of cisplatin involves TrxR inhibition. We hypothesize that the anticancer drug nedaplatin (NDP), an analogue of cisplatin and a second-generation platinum complex, also targets TrxR. Furthermore, we investigate whether the therapeutic efficacy of NDP can be enhanced by simultaneous modulation of 1) TrxR, via NDP, and 2) glutathione (GSH), via the GSH synthesis inhibitor buthionine sulfoximine (BSO). Mice bearing ascitic hepatoma 22 (H22) cells were treated with NDP alone or NDP plus BSO. TrxR activity of H22 cells was inhibited by NDP in a dose-dependent manner. A high correlation between the inhibition of TrxR activity at 6 h and the inhibition of ascitic fluid volume at 72 h was established (r = 0.978, p < 0.01). As an adaptive response, the viable ascitic cancer cells after NDP treatment displayed an enlarged cell phenotype, assembled with several-fold more antioxidant enzymes and GSH-predominant non-protein free thiols. This adaptive response was largely eliminated when BSO was co-administered with NDP, leading to the decimation of the H22 cell population without enhancing renal toxicity, since at this dose, NDP did not inhibit renal TrxR activity. In conclusion, the pharmacological effect of NDP involves TrxR inhibition, and the adaptive response of NDP-treated ascitic H22 cells can be efficiently counteracted by BSO. Simultaneous modulation of TrxR and GSH on ascitic H22 cells using NDP plus BSO greatly enhances therapeutic efficacy as compared with the single modulation of TrxR using NDP alone. -- Highlights: ► Nedaplatin at a pharmacological dose inhibits TrxR in cancer cells but not in kidney. ► The nedaplatin-treated cancer cells exhibit adaptive response. ► Buthionine sulfoximine inhibits glutathione in both cancer cells and kidney. ► Buthionine sulfoximine counteracts the adaptive response to the nedaplatin treatment. ► Buthionine sulfoximine does not

    The aim was to compare late-time extrapolation of plasma clearance (CL) from Tikhonov adaptively regularized gamma variate fitting (Tk-GV) and from mono-exponential (E1) fitting. Ten {sup 51}Cr-ethylenediaminetetraacetic acid bolus IV studies in adults - 8 with ascites - assessed for liver transplantation, with 12-16 plasma samples drawn from 5-min to 24-h, were fit with Tk-GV and E1 models and CL results were compared using Passing-Bablok fitting. The 24-h CL(Tk-GV) values ranged from 11.4 to 79.7 ml/min. Linear regression of 4- versus 24-h CL(Tk-GV) yielded no significant departure from a slope of 1, whereas the 4- versus 24-h CL(E1) slope, 1.56, was significantly increased. For CL(Tk-GV-24-h) versus CL(E1-24-h), there was a biased slope and intercept (0.85, 5.97 ml/min). Moreover, the quality of fitting of 24-h data was significantly better for Tk-GV than for E1, as follows. For 10 logarithm of concentration curves, higher r values were obtained for each Tk-GV fit (median 0.998) than for its corresponding E1 fit (median 0.965), with p < 0.0001 (paired t-test of z-statistics from Fisher r-z transformations). The E1 fit quality degraded with increasing V/W [volume of distribution (l) per kg body weight, p=0.003]. However, Tk-GV fit quality versus V/W was uncorrelated (p=0.8). CL(E1) values were dependent on sample time and the quality of fit was poor and degraded with increasing ascites, consistent with current opinion that CL(E1) is contraindicated in ascitic patients. CL(Tk-GV) was relatively more accurate and the good quality of fit was unaffected by ascites. CL(Tk-GV) was the preferred method for the accurate calculation of CL and was useful despite liver failure and ascites. (orig.)

  2. Magnetic resonance elastography in the detection of hepatorenal syndrome in patients with cirrhosis and ascites

    International Nuclear Information System (INIS)

    Hepatorenal syndrome (HRS) is the most lethal cause of renal impairment in cirrhosis. Magnetic resonance elastography (MRE) is a diagnostic test that characterises tissues based on their biomechanical properties. The aim of this study was to assess the feasibility of MRE for detecting HRS in cirrhotic patients. A prospective diagnostic investigation was performed. Renal MRE was performed on 21 hospitalised patients with cirrhosis and ascites. Six patients had HRS, one patient had non-HRS renal impairment, and 14 patients had normal renal function. The MRE-measured renal stiffness was compared against the clinical diagnosis as determined by clinical review alongside laboratory and radiologic results. The MRE-measured renal stiffness was significantly lower in patients with HRS (median stiffness of 3.30 kPa at 90 Hz and 2.62 kPa at 60 Hz) compared with patients with normal renal function (median stiffness of 5.08 kPa at 90 Hz and 3.41 kPa at 60 Hz) (P ≤ 0.014). For the detection of HRS, MRE had an area under the receiver operating characteristic curve of 0.94 at 90 Hz and 0.89 at 60 Hz. MRE had excellent inter-rater agreement, as assessed by Bland-Altman and intraclass correlation coefficient (> 0.9). MRE shows potential in the detection of HRS. (orig.)

    To study the effects of diallyl sulfide (DAS), an organosulfur compound present in garlic (Allium sativum),on the life span ofehrlich ascites (EA) tumor bearing Swiss albino mice, cytotoxicity and angiogenesis. Methods EA tumor cells were maintained by serial transplantation in peritoneal cavity of male Swiss albino mice. EA tumor cells were inoculated at concentrations of 1 × 106EA cells, 2.5 × l06EAcells and 5 × 106 EA cells. DAS was given in 0.2 mi normal saline i. p., daily for seven days followed one hour later by inoculation with EA cells in respective groups. Results The results revealed that administration of DAS increased the life span of EA tumor bearing animals by more than 25 percent. A significant dose dependant cytotoxic response of DAS was also observed on EA tumor cells. DAS was also found to inhibit the angiogenesis in EA tumor bearing mice in a dose dependent manner. Conclusion It is suggested that DAS may exert its anticarcinogenic effects by more than one mechanism and is a useful chemopreventive and chemotherapeutic agent.

  4. Turnover of phosphocholine and phosphoethanolamine in ether-phospholipids of Krebs II ascite cells

    International Nuclear Information System (INIS)

    Krebs II ascite cells suspended in Eagle medium were incubated at 37 C for up to 6 hr in the presence of [3H] glycerol or [32P] orthophosphate. After extraction, their lipids were treated with guinea pig phospholipase A1 under conditions where all diacyl-phospholipids (diacyl-PL) became hydrolyzed with 55% recovery of lyso-PL. Using a bidimensional thin layer chromatography (TLC) involving exposure to HCl fumes between the two runs, it then became possible to determine at once the specific radioactivity of the three subclasses present in choline glycerophospholipids (CGP) and ethanolamineglycerophospholipids (EGP). Compared to diacyl-PL, a lower de novo synthesis of ether subclasses was evidenced in both CGP and EGP by [3H] glycerol incorporation. Although the same profile was obtained for CGP with [32P] orthophosphate, the three EGP subclasses displayed in this case the same specific radioactivity. These data indicate a higher turnover rate of the polar head group of ether-EGP compared to either-CGP. The simple methodology used in the present study might thus prove helpful in developing enzymatic studies dealing with the mechanism of this accelerated renewal

    The fibrolamellar variant of hepatocellular carcinoma (FL-HCC) is distinguished from other hepatocellular carcinoma's (HCC) by its unique clinical and pathological features. Cytological features of this tumor on fine needle aspiration have been described earlier. We report a rare case of a 17-year-old African American male with metastatic FL-HCC, diagnosed by body fluid cytology. The patient presented with ascites and computed tomography (CT) scan revealed multiple omental masses and liver lesions. The fluid sample was obtained along with the omental biopsy and was found positive for metastatic fibrolamellar hepatocellular carcinoma. The fluid cytology showed atypical polygonal cells with enlarged nuclei, prominent nucleoli, and abundant granular cytoplasm. Cytomorphologic features of FL-HCC presenting in body fluids have been rarely described before. This case enriches the cytopathology literature by providing awareness of this tumor presenting as metastasis in body fluids, especially in young individuals with liver lesions. Presence of a concurrent biopsy specimen provided cytohistological correlation, as it remains the gold standard for the accuracy and reliability of cytological diagnoses. Diagn.

    The effect of Paclitaxel (PAC), Epirubicin (EPR) and Tamoxifen (TAM) on ''3H-thymidine labelling index (''3H-TdR LI) of Ehrlich ascites tumor cells (EAT) was investigated in cultured. In the present study, an estrogen receptor positive ER(+) hyper diploid cell lines were studied. We used optimum doses of PAC, EPR and TAM (12 mg/ml, 12 mg/ml and 2 mg/ml, respectively). Cells were treated with these doses for 0, 4, 8, 16 and 32 hours. At the end of these periods, both control and treated cells were labelled for 5 mCi/ml 3H-thymidine for 30 minutes. The results showed that inhibition of DNA synthesis in cultured EAT cells were increased in the combined treatment of two drugs when compared to the treatment of a single drug (p<0.01). In the treatment of three drugs, however, this effect reached a maximum (p<0.001). As a result, PAC+EPR+TAM treatment's had a maximum synergistic effect at 4 hours treatment

    Full Text Available The effect of Crotalus durissus terrificus (LAURENTI, 1768 venom on the evolution of Ehrlich ascites tumor cells was evaluated. Thus, 30-day-old male mice of the Swiss strain were inoculated intraperitoneally with 1x10 tumor cells. Then, 7 groups of animals were formed: 3 control groups (physiological, venom and tumor and 4 experimental groups that received different doses of venom. The experimental groups received 5 intraperitoneal venom injections on the 1 , 4 , 7 , 10 and 13 days after tumor implantation. On the 14 day, 5 animals from each one of the groups were sacrificed, and the variables such as the total and differential counts of cells in the peritoneal cavity and functional state of peritoneal macrophages by macrophage spreading were evaluated. The other 5 remaining animals were kept in the laboratory for 60 days for observation of their survival percentage. The results obtained were statistically analyzed by the Kruskal-Wallis test at 5% significance level. It was observed that Crotalus durissus terrificus venom increases survival time of mice, but does not increase mortality percentage. This venom also increases the percentage of macrophage spreading. We suggest that snake venoms can cause inhibition of tumor growth by activating the inflammatory reaction, mainly the macrophages, stimulating the production of TNF- , IL-1, IL-6 and IL-8. These cytokines may act on tumor cells by different mechanisms, inducing its complete elimination.

  8. Properties of a purified nucleolar ribonuclease from Ehrlich ascites carcinoma cells.

    1980-06-24

    A nucleolar ribonuclease specific for single-stranded ribonucleic acid (RNA) has been isolated and extensively purified from Ehrlich ascites carcinoma cells. The enzyme is optimally active at neutral pH and degrades RNA via a 2',3'-cyclic intermediate leaving 3'- or 2',3'-cyclic terminated oligonucleotides. The ribonuclease has an apparent molecular weight of 38 500 as judged by sedimentation equilibrium and is a basic protein having an isoelectric point greater than 9.0. The enzyme preferentially cleaves poly(C) over poly (U), poly(A), or poly(C).poly(I). Limit digestion products of poly(C) degratation are on the average tri-, tetra-, and pentanucleotides. In the partial digestion of yeast 5.8S rRNA, the nucleolar ribonuclease cleaves only CpA phosphodiester bonds. Spermidine, spermine, and histone I inhibit the activity of nucleolar ribonuclease. Antibodies directed toward pancreatic RNase do not cross-react with the Ehrlich nucleolar ribonuclease. PMID:7397114

  11. An investigation of the shedding of macromolecules from the Ehrlich mouse ascites tumor cell

    International Nuclear Information System (INIS)

    The spontaneous release, or shedding, of cell surface components into the extracellular medium may be important in the determination of several features of the cancer cell phenotype. The release of macromolecules from the Erhlich mouse ascites tumor cell was studied under a variety of experimental conditions to elucidate the origin and the underlying mechanisms of release. The extrinsic macromolecules are a diverse group with apparent molecular weights ranging from 13,500 to 400,000 daltons. External labeling of the cell surface with tritiated 4,4'-diisothiocyano-1,2-diphenylethane-2,2-disulfonic acid ([3H]H2DIDS) reveals a slow loss of labeled components at 4 degrees C, while at 21 degrees C and 37 degrees C an initial rapid loss is followed by a slower release. In vitro metabolic labeling with [1-14C]-D-glucosamine hydrochloride, D-[2-3H]-mannose and various [3H]-L-amino acids results in the appearance of labeled macromolecules in the medium suggesting tumor, not mouse, origin. These data suggest that the extrinsic macromolecules originate from the cell surface. Macromolecules are shed by a temperature and pH sensitive process. These results suggest that a limited proteolytic digestion, or sublethal autolysis, of the cell surface may occur in this system. The macromolecules shed by the Ehrlich cell originate from the surface and are probably released by sublethal autolysis, direct secretion and a passive process

    Bi-212 is an alpha-emitting radionuclide being investigated as a therapeutic agent in the intraperitoneal treatment of micrometastatic ovarian carcinoma. In evaluating a new therapeutic modality, cell-survival studies are often used as a means of quantifying the biological effects of radiation. In this analysis, Ehrlich ascites cells were irradiated under conditions similar to therapy in various concentrations of Bi-212. Immediately following irradiation, a cell survival assay was performed in which cells were plated and colonies were counted after 10--14 days. Both a macrodosimetric and a microdosimetric approach were used in analyzing these data. These models used as input the fraction of activity within the cell and in solution, the distribution of cell sizes, and the variation of LET along individual alpha-particle tracks. The results indicate that the energy deposited within the nucleus varies significantly among individual cells. There is a small fraction of cell nuclei which receive no hits, while the remaining cells receive energy depositions which can differ significantly from the mean value. These dosimetric parameters are correlated with measured cell survival and will be a useful predictor of outcome for therapeutic doses.

    (1) Genetic parameters for the sudden death syndrome (SDS) were estimated in meat-type chickens. Data were collected over 11 generations of selection for body weight within two distinct breeds (Cornish and White Rock). (2) The animal model was used exclusively with linear methods (LM) to estimate genetic parameters. Heritability (h2) of SDS on the liability scale was 0.30 +/- 0.002 and 0.25 +/- 0.002 in the Cornish and White Rock breeds, respectively. (3) A positive genetic correlation (r(g)) with ascites (AS) was determined (approximately 0.3 +/- 0.006). However, it was not possible to estimate the rg of SDS with body weight because of the low prevalence of the defect trait studied (1.8% in the Cornish and 1-5% in the White Rock). (4) Heritability of SDS calculated using male records only was 0.45 +/- 0.009 and 0.35 +/- 0.009, and r(g) with body weight was 0.30 +/- 0.010 and 0.27 +/- 0.009, in the Cornish and White Rock breeds, respectively. (5) In conclusion, the heart defect investigated was heritable with a positive genetic correlation with AS and body weight. PMID:15835252

    Objective:To study the effect of S-1 combined with cisplatin intraperitoneal circulatory hyperthermia perfusion on malignant molecule expression in gastric cancer patients with ascites as well as the related side effect.Methods: Gastric cancer patients with ascites who were treated in our hospital from February 2012 to July 2015 were selected as research subjects and randomly divided into perfusion chemotherapy group and routine chemotherapy group, and then overall chemotherapy conditions, ascites FGF molecule content, peripheral blood immune function indexes and the degree of side effect were compared between two groups. Results:Average treatment cycles of perfusion chemotherapy group were more than those of routine chemotherapy group, and ascites drainage volume within two cycles of chemotherapy was significantly less than that of routine chemotherapy group; after two cycles of chemotherapy, bFGF, FGF-2, FGF19 and FGFR4 content in ascites of perfusion chemotherapy group were significantly lower than those of routine chemotherapy group, CD3+CD4+, CD3+CD56+ and CD3-CD56+ cell content in peripheral blood were higher than those of routine chemotherapy group, and CD3+CD8+ cell content was lower than that of routine chemotherapy group; during chemotherapy, the number of cases with decreased numeration of leukocyte, abnormal liver function, abnormal kidney function and diarrhea of perfusion chemotherapy group were significantly lower than those of routine chemotherapy group.Conclusions: S-1 combined with cisplatin intraperitoneal circulatory hyperthermia perfusion chemotherapy can more effectively improve treatment compliance, suppress ascites, kill gastric cancer cells and improve immune function. It has fewer side effect and is the ideal way to treat gastric cancer with ascites.

    Ascites or pulmonary hypertension syndrome is a metabolic disorder in broilers. Male broilers have a higher BW and are therefore expected to be more prone to developing ascites than females. As genetic parameters might be affected by the ascites incidence, genetic parameters might differ between male and female broilers. The aims of this study were to estimate the heritability for the ratio of right ventricular weight to total ventricular weight (RATIO) and BW in male and female broilers, the genetic correlation between RATIO and BW separately for male and female broilers, and the genetic correlations between BW for ascitic and nonascitic broilers. Data were available from 7,856 broilers (3,819 males and 4,037 females). The broilers in the experiment were kept under a cold temperature regimen and increased CO(2) levels. In this study, we showed that the incidence of ascites is higher in male than in female broilers. Heritability estimates for BW at 7 wk of age were higher for male (0.22) than for female (0.17) broilers, and for RATIO heritability, estimates were higher for female (0.44) than for male (0.32) broilers. The genetic correlations between RATIO and BW measured at different ages changed from slightly positive at 2 wk of age to moderately negative at 7 wk. The change in genetic correlation was more extreme for male (from 0.01 to -0.62) than for female (from 0.13 to -0.24) broilers. The difference in ascites incidence between male and female broilers is the most likely reason for the difference in genetic correlations. The genetic correlation between BW traits measured in broilers with fluid in the abdomen and without fluid in the abdomen decreased from 0.91 at 2 wk to 0.69 at 7 wk. We conclude that under circumstances with ascites, data from male and female broilers should be analyzed separately. PMID:22334730

    The effect of lonidamine, an antispermatogenic and antitumor drug, on the oxygen consumption, ATPase activity, and redox state of the electron carriers of Ehrlich ascites tumor mitochondria has been studied. Lonidamine inhibits ADP- and uncoupler-stimulated respiration on various NAD- and FAD-linked substrates, but does not affect state 4 respiration. Experiments to determine its site of action showed that lonidamine does not significantly inhibit electron flow through cytochrome oxidase. Electron flow through site 2, the ubiquinone-cytochrome b-cytochrome c1 complex, also was unaffected by lonidamine, which failed to inhibit the oxidation of duroquinol. Moreover, inhibition of electron flow through site 2 was also excluded because of the inability of the N,N,N',N'-tetramethyl-p-phenylenediamine bypass to relieve the lonidamine inhibition of the oxidation of pyruvate + malate. The F0F1ATPase activity and vectorial H+ ejection are also unaffected by lonidamine. The inhibition of succinate oxidation by lonidamine was found to take place at a point between succinate and iron-sulfur center S3. Spectroscopic experiments demonstrated that lonidamine inhibits the reduction of mitochondrial NAD+ by pyruvate + malate and other NAD-linked substrates in the transition from state 1 to state 4. However, lonidamine does not inhibit reduction of added NAD+ by submitochondrial vesicles or by soluble purified NAD-linked dehydrogenases. These observations, together with other evidence, suggest that electron transport in tumor mitochondria is inhibited by lonidamine at the dehydrogenase-coenzyme level, particularly when the electron carriers are in a relatively oxidized state and/or when the inner membrane-matrix compartment is in the condensed state. The action of lonidamine in several respects resembles the selective inhibition of electron transport in tumor cells produced by cytotoxic macrophages (D. L. Granger and A. L. Lehninger (1982) J. Cell Biol. 95, 527). PMID:6227286

    The development of tools for functional diagnostic imaging is mainly based on radiopharmaceuticals that specifically target membrane receptors. Crotoxin (Crtx), a polypeptide isolated from Crotalus durissus terrificus venom, has been shown to have an antitumoral activity and is a promising bioactive tracer for tumor detection. More specific radiopharmaceuticals are being studied to complement the techniques applied in the conventional medicine against breast cancer, the most frequent cause of death from malignant disease in women. Crtx's effect has been shown to be related with the overexpression of epidermal growth factor receptor (EGFR), present in high levels in 30 to 60% of breast tumor cells. Our objective was to evaluate Crtx as a tracer for cancer diagnosis, investigating its properties as an EGFR-targeting agent. Ehrlich ascites tumor cells (EAT cells) were used due to its origin and similar characteristics to breast tumor cells, specially the presence of EGFR. Crtx was labeled with 125I and binding experiments were performed. To evaluate the specific binding in vitro of Crtx, competition binding assay was carried out in the presence of increasing concentrations of non-labelled crotoxin and epidermal growth factor (EGF). Specific binding of 125I-Crtx to EAT cells was determined and the binding was considered saturable, with approximately 70% of specificity, high affinity (Kd = 19.7 nM) and IC50 = 1.6 x 10-11 M. Our results indicate that Crtx's interaction with EAT cells is partially related with EGFR and increases the biotechnological potential of Crtx as a template for radiopharmaceutical design for cancer diagnosis.

    Background Pulmonary arterial hypertension, also known as Ascites syndrome (AS), remains a clinically challenging disease with a large impact on both humans and broiler chickens. Pulmonary arterial remodeling presents a key step in the development of AS. The precise molecular mechanism of pulmonary artery remodeling regulating AS progression remains unclear. Methodology/Principal Findings We obtained pulmonary arteries from two positive AS and two normal broilers for RNA sequencing (RNA-seq) analysis and pathological observation. RNA-seq analysis revealed a total of 895 significantly differentially expressed genes (DEGs) with 437 up-regulated and 458 down-regulated genes, which were significantly enriched to 12 GO (Gene Ontology) terms and 4 KEGG (Kyoto Encyclopedia of Genes and Genomes) pathways (Padj<0.05) regulating pulmonary artery remodeling and consequently occurrence of AS. These GO terms and pathways include ribosome, Jak-STAT and NOD-like receptor signaling pathways which regulate pulmonary artery remodeling through vascular smooth cell proliferation, inflammation and vascular smooth cell proliferation together. Some notable DEGs within these pathways included downregulation of genes like RPL 5, 7, 8, 9, 14; upregulation of genes such as IL-6, K60, STAT3, STAT5 Pim1 and SOCS3; IKKα, IkB, P38, five cytokines IL-6, IL8, IL-1β, IL-18, and MIP-1β. Six important regulators of pulmonary artery vascular remodeling and construction like CYP1B1, ALDH7A1, MYLK, CAMK4, BMP7 and INOS were upregulated in the pulmonary artery of AS broilers. The pathology results showed that the pulmonary artery had remodeled and become thicker in the disease group. Conclusions/Significance Our present data suggested some specific components of the complex molecular circuitry regulating pulmonary arterial remodeling underlying AS progression in broilers. We revealed some valuable candidate genes and pathways that involved in pulmonary artery remodeling further contributing to the AS

  20. Current Management of the Complications of Cirrhosis and Portal Hypertension: Variceal Hemorrhage, Ascites, and Spontaneous Bacterial Peritonitis.

    2016-01-01

    Cirrhosis is not a single entity but represents a disease progression across different prognostic stages, with the compensated and decompensated stages being the most important. Variceal hemorrhage (VH) and ascites are complications of cirrhosis that denote the presence of a decompensated stage. Spontaneous bacterial peritonitis (SBP) is a common bacterial infection unique to patients with cirrhosis that can precipitate the development of recurrent VH and hepatorenal syndrome (HRS), complications that denote the presence of a 'further decompensated' stage of cirrhosis. Main current issues in the management of VH include identification of different prognostic stages that allow for individualized patient care. Management of VH cannot be performed in an isolated manner, and the presence of other complications of cirrhosis (ascites, encephalopathy) should be taken into account both in the management and in the design of clinical trials. Because management of ascites per se has not resulted in significant changes in mortality, main management issues consist of preventing further decompensating events by preventing factors that will lead to worsening vasodilatation and hemodynamic status (infections, vasodilators), preventing volume depletion (overdiuresis, GI hemorrhage) and preventing structural kidney injury (nephrotoxins). Prophylaxis of bacterial infections such as SBP currently consists of the administration of antibiotics. By preventing infections, there is evidence that recurrent VH and HRS can also be prevented. However, response to recommended empirical antibiotics in patients with suspected infection, such as SBP, is currently significantly lower than in the past because of an increase in infections secondary to multidrug resistant (MDR) organisms. One of the main predictors of the development of MDR organisms is antibiotic prophylaxis and unnecessary and prolonged use of antibiotics in hospital. Therefore, appropriate antibiotics should be used in patients

  1. Evaluation of hollow fiber and mini perm bioreactors as an alternative to murine ascites for small scale monoclonal antibody production

    International Nuclear Information System (INIS)

    The objective of this study was to compare monoclonal antibody production in hollow fiber, mini perm bioreactor systems and murine ascites to determine the feasibility of the bioreactor system as a potential alternative to the use of mice. One hybridoma cell line was grown in hollow fiber, mini perm bioreactor systems and in groups of 5 mice. Mice were primed with 0.5 ml pristane intraperitoneally 14 days prior to inoculation of 1x107 hybridoma cells. Each mouse was tapped a maximum of three times for collection of ascites. Bioreactors were harvested three times weekly for 30 days and were monitored by cell counts, cell viability and media consumption. Time and materials logs were maintained. The total quantity of monoclonal antibody produced in 5 mice versus the total production for the two different bioreactors (hollow fiber and mini perm) in 30 days was as follows: cell line 2AC10E6C7 produce 158 mg vs.97.5 mg, vs 21.54 mg respectively. Mean monoclonal antibody concentration ranged from 4.07 to 8.37 mg/ml in murine ascites, from 0.71 to 3.8 mg/ml in hollow fiber bioreactor system, and from 0.035 to 1.06 in mini perm. Although time and material costs were generally greater for the bioreactors, these results suggest that hollow fiber and mini perm bioreactor systems merit further investigations as potentially viable in vitro alternatives to the use of mice for small scale (<1mg) monoclonal antibody production.(Author)

    Full Text Available We present the first case of an early infantile form of galactosialidosis among Brazilians. This very rare and severe lysosomal storage disease has only a dozen patients clearly diagnosed worldwide. Clinical, pathological and biochemical features were consistent with previously published findings. We detected the disorder in a 7-month-old female baby with prenatal diagnosis of ascites. Evolution of the storage disease was monitored through routine thin-layer chromatography (TLC for urinary oligosaccharides as part of a screening program for inborn errors of metabolism (IEM in high-risk children, carried out in Rio de Janeiro.

    This report presented a case of 62-year-old woman who was admitted to our hospital for "cirrosis", but she had a variety of clinical manifestations,such as abdominal distension,diarrhea,ascites, hepatosplenomegaly,anemia, palpitation, flushing, low blood pressure, arrhythmia and so on. Upper gastrointestinal endoscopy showed thicken mucosa at gastric fundus. Colonoscopy revealed nodular, pseudopolypoid. Ascitic fluid test suggested a transudate. Endoscopic abnormal mucosa biopsy showed chronic inflammation. Many mast cells were seen in bone marrow and liver biopsies,and liver tissue immunophenotype was CD117, and CD68. Thus the patient's diagnosis was systemic mastocytosis. It is rare that a patient only has the gastrointestinal tract symptoms complicated with ascites without skin lesion. The goal for treatment was to reduce hypersecretion of mast cells.

    The total plasma (Clt) and the renal plasma (Clr) clearances of [51Cr]EDTA were determined simultaneously in nine patients with ascites due to liver cirrhosis. Clt (mean 78 ml/min, range 34-115 ml/min) was significantly higher than Clr (mean 52 ml/min, range 13-96 ml/min, P < 0.005). The ascitic...... fluid-plasma activity ratio of [51Cr]EDTA increased throughout the investigation period (5h). The results suggest that [51Cr]EDTA equilibrates slowly with the peritoneal space which indicates that Clt will over-estimate the glomerular filtration rate by approximately 20 ml/min in patients with ascites...

    The pharmacokinetics and internal radionuclide therapy of intraperitoneally administrated {sup 188}Re-N,N-bis(2-mercaptoethyl)-N',N'-diethylethylenediamine (BMEDA)-labeled pegylated liposomal doxorubicin ({sup 188}Re-DXR-liposome) were investigated in the C26 murine colon carcinoma ascites mouse model. After intraperitoneal administration of the nanotargeted bimodality {sup 188}Re-DXR-liposome, the ascites and tumor accumulation of the radioactivity were observed, the levels of radioactivity within the ascites were maintained at relatively higher levels before 48 h and the levels of radioactivity in the tumor were maintained at steady levels after 4 h. The AUC{sub (o{yields}{infinity})} of {sup 188}Re-DXR-liposome in blood, ascites and tumor was 9.3-, 4.2- and 4.7-fold larger than that of {sup 188}Re-BMEDA, respectively. The maximum tolerated dose of intraperitoneally administrated {sup 188}Re-DXR-liposome was determined in normal BALB/c mice. The survival, tumor and ascites inhibition of mice after {sup 188}Re-DXR-liposome (22.2 MBq of {sup 188}Re, 5 mg/kg of DXR) treatment were evaluated. Consequently, radiochemotherapeutics of {sup 188}Re-DXR-liposome attained better survival time, tumor and ascites inhibition (decreased by 49% and 91% at 4 days after treatment; P<.05) in mice than radiotherapeutics of {sup 188}Re-liposome or chemotherapeutics of Lipo-Dox did. Therefore, intraperitoneal administration of novel {sup 188}Re-DXR-liposome could provide a benefit and promising strategy for delivery of passive nanotargeted bimodality radiochemotherapeutics in oncology applications.

  10. Application of Meal Feeding and Skip-A-Day Feeding With or Without Probiotics for Broiler Chickens Grown at High-Altitude to Prevent Ascites Mortality

    2010-01-01

    Full Text Available Problem statement: Ascites is a common rapid-growth-related problem in broiler chickens grown at high altitude where the partial pressure of oxygen is low and is marginally adequate to support the growth performance and ascites-related variables. A mismatch between the growth of oxygen supplying organs and the oxygen demanding organs causes ascites in broiler chickens. In the present study, broilers were subjected to two types of feed restriction with or without probiotics and changes in the growth rate of body organs were attributed to the incidence of ascites. Approach: Four hundred male day-old broiler chicks were randomly assigned in a completely randomized design to five treatments: (1 a control group fed ad libitum throughout the experiment (2 a group subjected to meal feeding during 5-11 days of age with feeding times from 08-12 h and 13-17 h, (3 a group similar to treatment 2 except to received probiotics, (4 a skip-a-day feeding with 24 h fasting on days 9 and 11 and (5 a group similar to treatment 4 except to received probiotics. Probiotics was only used during the feed restriction at 1 g L-1 in the drinking water. Broilers reared on litter flooring from 1-49 days of age. Results: Both feed restriction programs used under conditions of the experiment resulted in poorer performance relative to the full-fed control but retarded growth caught up at the end of experiment. Carcass and breast yield were significantly (p‎Conclusion: Early feed restriction did not influence the proportional growth of body organs and had no significant impact on ascites incidence. Probiotics had a positive effect in prevention of ascites.

    Effects of dietary L-carnitine and coenzyme Q10 (CoQ10) at different supplemental ages on performance and some immune response were investigated in ascites-susceptible broilers. A 3 x 2 x 2 factorial design was used consisting of L-carnitine supplementation (0, 75, and 100 mg/kg), CoQ10 supplementation (0 and 40 mg/kg) and different supplemental ages (from day 1 on and from day 10 on). A total of 480 one-day-old Arbor Acre male broiler chicks were randomly allocated to 12 groups, every group had five replicates, each with eight birds. The birds were fed a corn-soybean based diet for six weeks. From day 10-21, all the birds were exposed to a low ambient temperature (12-15 degrees C) to increase the susceptibility to ascites. No significant effects were observed on growth performance by L-carnitine, CoQ10 supplementation, and different supplemental ages. Packed cell volume was significantly decreased by L-carnitine supplementation alone, and ascites heart index and ascites mortality were decreased by L-carnitine, CoQ10 supplementation alone, and L-carnitine + CoQ10 supplementation together (p broilers was significantly improved by L-carnitine, CoQ10 supplementation alone during 0-3 week. Serum IgG content was improved by L-carnitine supplementation alone (p ascites-susceptible broilers, which might benefit for the reduction of broilers' susceptibility to ascites. PMID:17361948

    Full Text Available Chylous ascites is very rare in HIV/AIDS and its association with Mycobacterium avium complex-immune reconstitution inflammatory syndrome (MAC-IRIS has been rarely reported. Here, we report a case of a young African-American male who developed chylous ascites as a late sequela to immune reconstitution inflammatory syndrome while on treatment for MAC. Antiretroviral drug-naive patients who start HAART in close proximity to the diagnosis of an opportunistic infection and have a rapid decline in HIV RNA level should be monitored for development of IRIS. Although the long term prognosis is poor, early diagnosis and treatment help to improve quality of life.

  13. Does Artificial Ascites Induce the Heat-Sink Phenomenon during Percutaneous Radiofrequency Ablation of the Hepatic Subcapsular Area?: an in vivo Experimental Study Using a Rabbit Model

    International Nuclear Information System (INIS)

    To evaluate the effect of the heat-sink phenomenon induced by artificial ascites on the size of the ablation zone during percutaneous radiofrequency (RF) ablation of the hepatic subcapsular area in an in vivo rabbit model. A total of 21 percutaneous rabbit liver RF ablations were performed with and without artificial ascites (5% dextrose aqueous solution). The rabbits were divided into three groups: a) control group (C, n = 7); b) room temperature ascites group (R, n = 7); and c) warmed ascites group (W, n = 7). The tip of a 1 cm, internally cooled electrode was placed on the subcapsular region of the hepatic dome via ultrasound guidance, and ablation was continued for 6 min. Changes in temperature of the ascites were monitored during the ablation. The size of the ablation zones of the excised livers and immediate complications rates were compared statistically between the groups (Mann-Whitney U test, Kruskal-Wallis test, linear-by-linear association, p = 0.05). One rabbit from the 'W' group expired during the procedure. In all groups, the ascites temperatures approached their respective body temperatures as the ablations continued; however, a significant difference in ascites temperature was found between groups 'W' and 'R' throughout the procedures (39.2± 0.4 .deg.

    To evaluate the effect of the heat-sink phenomenon induced by artificial ascites on the size of the ablation zone during percutaneous radiofrequency (RF) ablation of the hepatic subcapsular area in an in vivo rabbit model. A total of 21 percutaneous rabbit liver RF ablations were performed with and without artificial ascites (5% dextrose aqueous solution). The rabbits were divided into three groups: a) control group (C, n = 7); b) room temperature ascites group (R, n = 7); and c) warmed ascites group (W, n = 7). The tip of a 1 cm, internally cooled electrode was placed on the subcapsular region of the hepatic dome via ultrasound guidance, and ablation was continued for 6 min. Changes in temperature of the ascites were monitored during the ablation. The size of the ablation zones of the excised livers and immediate complications rates were compared statistically between the groups (Mann-Whitney U test, Kruskal-Wallis test, linear-by-linear association, p = 0.05). One rabbit from the 'W' group expired during the procedure. In all groups, the ascites temperatures approached their respective body temperatures as the ablations continued; however, a significant difference in ascites temperature was found between groups 'W' and 'R' throughout the procedures (39.2+- 0.4 .deg. C in group W and 33.4+-4.3 .deg. C in group R at 6 min, p = 0.003). No significant difference was found between the size of the ablation zones (782.4+-237.3 mL in group C, 1,172.0+-468.9 mL in group R, and 1,030.6+-665.1 mL in group W, p = 0.170) for the excised liver specimens. Diaphragmatic injury was identified in three of seven cases (42.9%) upon visual inspection of group 'C' rabbits (p = 0.030).

  15. First-line radiofrequency ablation with or without artificial ascites for hepatocellular carcinomas in a subcapsular location: Local control rate and risk of peritoneal seeding at long-term follow-up

    International Nuclear Information System (INIS)

    Aim: To compare the long-term local control of hepatocellular carcinoma (HCC) and risk of peritoneal seeding via percutaneous radiofrequency ablation (RFA) using artificial ascites with those of RFA without artificial ascites. Materials and methods: The Institutional Review Board approved this retrospective study. From April 2005 to February 2008, 160 patients (121 men, 39 women; age range 36–79 years) with a single subcapsular HCC (mean size 2.19 cm) were treated with ultrasonography-guided percutaneous RFA as a first-line therapy. Forty-four patients were treated with RFA using artificial ascites, whereas the other 116 patients were treated without artificial ascites. The cumulative local tumour progression (LTP) and peritoneal seeding were compared in both groups using follow-up computed tomography (CT). Cumulative LTP rates were analysed using the Kaplan–Meier method and the log-rank test. Risk of peritoneal seeding was investigated by means of multivariate analysis. Results: The overall median follow-up period was 52.5 months (range 13–76 months). The 1, 2, 4, and 6 year cumulative LTP rates were 17.1, 27.6, 35.2, and 35.2%, respectively, in the group with artificial ascites, and 8, 15.2, 26.6, and 34.4% in the group without artificial ascites, without significant difference (p = 0.332). The rates of peritoneal seeding were 6.8% (3/44) in the group with artificial ascites and 2.6% (3/116) in the group without artificial ascites, a non-significant difference (p = 0.347). The biopsy prior to RFA was the independent risk factor of peritoneal seeding regardless of the use of artificial ascites. Conclusion: Long-term local tumour control and risk of peritoneal seeding were comparable for RFA with or without artificial ascites when used as a first-line therapy for subcapsular HCC

    Small lymphocytes sampled from intraperitoneally growing Ehrlich ascites tumour in CBA/H-T6 mice as well as host spleen and blood at different days of tumour development were characterized radioautographically on the basis of two surface markers, IgM for B cells and θ antigen for T cells. A direct binding of 125I-labelled anti-IgM detected natural surface IgM, while an indirect binding following a prior exposure to anti-θ antibody detected θ antigen. Cells remaining unlabelled with the latter procedure were considered to lack both markers (double negative). While the incidence of IgM+ve small lymphocytes within the tumour declined, their absolute numbers increased with tumour growth. Low levels of antiglobulin binding shown by these cells were considered to reflect low levels of maturation, because (1) our previous studies indicated that they were newly formed, and (2) the extent of antiglobulin binding by B lymphocytes in the marrow is known to increase with increasing post-mitotic age. The proportions and the absolute numbers of θ+ve as well as the double negative small lymphocytes increased within the growing tumours. Within the host spleen, the incidence of IgM+ve small lymphocytes remained unchanged but their absolute numbers increased because of splenomegaly. The degree of antiglobulin binding by these cells was comparable to that of the normal splenic population. The incidence of θ+ve cells dropped but their absolute numbers remained unchanged in the spleen during tumour growth. In contrast, the incidence as well as the absolute numbers of double negative cells increased markedly. This cell category increased also in the blood, possibly in transit to the tumour site and other lymphoid organs from the bone marrow, where they were most prevalent. Their bone marrow origin was further suggested by a preponderance of marrow derived small lymphocytes at the tumour site as well as in the host spleens found in our earlier studies.

    We tried to understand why our earlier estimates of fatty acid (FA) oxidation rates under the nearly anaerobic state of the Ehrlich ascites tumor (EAT) in vivo were even greater than those found in vitro under aerobic conditions. Using tracers [1-14C]linoleate, [1-14C]-, and [9,10-3H]palmitate, and NaH14CO3, we estimated essential and nonessential FA oxidation rates to CO2 + H2O by EAT in living mice and in vitro under aerobic and anaerobic conditions. Sequestration of intraperitoneally (ip)-injected 14C-FFA allowed a selective labeling of the tumor versus the host; thus, breath 14CO2 could be used to estimate the maximum rate of FA oxidation in vivo by the tumor. Initially, we measured breath 14CO2 following NaH14CO3 injections and developed a multicompartmental model to simulate the tumor-host HCO-3-CO2 system. This model was integrated with our earlier model for tumor FA turnover. The integrated model was fitted to breath 14CO2 data from mice injected ip with 14C-FFA to compute tumor FA oxidation rates. Both essential and nonessential FA were oxidized to CO2 at similar rates. The maximum rate of total FA oxidation to CO2 was 5-6 nmol FA X min-1 X 7-ml tumor-1, about 5-10 times lower than all previous estimates obtained in vitro and in vivo. To resolve this dilemma we used doubly labeled [1-14C; 9,10-3H]palmitate and found that under aerobic conditions, in vitro, EAT formed 3H2O and 14CO2 at nearly equal rates. These rates were suppressed markedly but unequally at low PO2. Anaerobic suppression of 14CO2 formation greatly exceeded that of 3H2O formation. As a result 3H2O/14CO2 reached a value of congruent to 10 at low PO2. Our data indicate that under the nearly anaerobic conditions of a growing EAT in vivo, the partial beta-oxidation of FA to 2C + H2O takes place at a 5 to 10 times faster rate than the complete oxidation of FA to CO2 + H2O. This finding can account for earlier apparent inconsistencies in the literature, since aerobic studies of 14C-FA oxidation

    Full Text Available Ziziphus mauritiana (Lamk. is a fruit tree that has folkloric implications against many ailments and diseases. In the present study, anticancer potential of seed extract of Ziziphus mauritiana in vitro against different cell lines (HL-60, Molt-4, HeLa, and normal cell line HGF by MTT assay as well as in vivo against Ehrich ascites carcinoma bearing Swiss albino mice was investigated. The extract was found to markedly inhibit the proliferation of HL-60 cells. Annexin and PI binding of treated HL-60 cells indicated apoptosis induction by extract in a dose-dependent manner. The cell cycle analysis revealed a prominent increase in sub Go population at concentration of 20 μg/ml and above. Agarose gel electrophoresis confirmed DNA fragmentation in HL-60 cells after 3 h incubation with extract. The extract also exhibited potent anticancer potential in vivo. Treatment of Ehrlich ascites carcinoma bearing Swiss albino mice with varied doses (100–800 mg/kg b.wt. of plant extract significantly reduced tumor volume and viable tumor cell count and improved haemoglobin content, RBC count, mean survival time, tumor inhibition, and percentage life span. The enhanced antioxidant status in extract-treated animals was evident from decline in levels of lipid peroxidation and increased levels of glutathione, catalase, and superoxide dismutase.

    Full Text Available In order to evaluate the accuracy of a urine reagent dipstick (Multistix 10SG® to determine ascitic fluid leukocyte count, we prospectively studied 106 cirrhotic patients from April 2003 to December 2004, in two different centers (Federal University of São Paulo - UNIFESP-EPM and Federal University of Juiz de Fora - HU-UFJF for the rapid bedside diagnosis of spontaneous bacterial peritonitis. The mean age 54 ± 12 years, there was a predominance of males (eighty-two patients, 77%, and alcohol was the most frequent etiology (43%. Forty-four percent of patients were classified as Child B and fifty-one as Child C (51%. Abdominal paracentesis was performed both in outpatient and inpatient settings and the Multistix 10SG® was tested. Eleven cases of spontaneous bacterial peritonitis were identified by means of polymorphonuclear count. If we considered the positive Multistix 10SG® result of 3 or more, the sensitivity, specificity, positive and negative predictive value were respectively 71%, 99%, 91% and 98%. With a positive reagent strip result taken as grade 2 (traces or more, sensitivity was 86% and specificity was 96% with positive and negative predictive values of 60% and 99%, respectively. Diagnostic accuracy was 95%. We concluded that the use of a urine reagent dipstick (Multistix 10SG® could be considered a quick, easy and cheap method for ascitic fluid cellularity determination in SBP diagnosis.

  1. Energy metabolism and ATP turnover time during the cell cycle in roentgen irradiated Ehrlich ascites tumour cells

    International Nuclear Information System (INIS)

    The cell-cycle related energy metabolism after roentgen irradiation of in vivo growing Ehrlich ascites tumour cells was investigated in cell fractions obtained by elutriator centrifuging. The oxygen consumption and the lactate and pyruvate production, measured in vitro after 4.5, 5 and 9 Gy up to 24 h, were undisturbed, while the decrease in the in vivo ATP content was dose-independent in all parts of the cell cycle. On the basis of these data the ATP turnover time was found to be decreased. The decrease in the ATP content is considered to be less likely to be due to membrane leakage or increased ATP consumption than to reduced ATP production. Since in vitro incubation normalizes the ATP content, it is suggested that environmental factors in the ascites liquid after irradiation cause a decrease in the ATP production. Low ATP contents of the cells do not appear to influence the irradiation-induced changes in the cell flow through the cell cycle. (Auth.)

    Pulmonary vascular remodelling, mainly characterized by arterial medial thickening, is an important pathological feature of broiler ascites syndrome (AS). Since vascular smooth muscle cells (VSMC) form the major cellular component of arterial medial layer, we speculate that VSMC proliferation is one of the causes of pulmonary arterial medial thickening in ascitic broilers. Hence, the present study was designed to investigate the role of VSMC proliferation in pulmonary vascular remodelling in development of AS induced by low ambient temperature. Broilers in control group (22 +/- 1.5 degrees C) and low temperature group (11 +/- 2 degrees C) were sampled every week at 15-50 days of age. Proliferative indexes of VSMC in pulmonary arteries were assessed with proliferating cell nuclear antigen, and the relative medial thickness (RMT) and relative wall area (RWA), as indexes of pulmonary vascular remodelling, were examined by computer-image analysing system. The results showed that the high incidence (18.75%) of AS was induced by low temperature, and a significantly increased VSMC proliferation was observed in pulmonary arteries in the low temperature group at 22-50 days of age (P < 0.05). In addition, RMT and RWA in pulmonary arteries were significantly elevated in the low temperature group from 36 days of age (P < 0.05), indicating that pulmonary vascular remodelling occurred following VSMC proliferation in AS. Our data suggest that proliferation of VSMC may facilitate pulmonary vascular remodelling and have a pivotal role in AS induced by low ambient temperature. PMID:18045340

    Full Text Available Objective: The present investigation was performed to evaluate the antiproliferative and antioxidant activity of Aegle marmelos leaves in Dalton′s Lymphoma Ascites (DLA-bearing mice. Materials and Methods: The DLA cells maintained in vivo in Swiss albino mice were used for developing ascitic tumor in mice by intraperitoneal transplantation. The standardized 50% ethanolic extract of A. marmelos leaves (AMEE was administered intraperitoneally in dose levels 200 and 400 mg/kg, after 24 hours of tumor inoculation in mice for two weeks. Results: The AMEE treatment significantly prevented (P<0.001 the increase in body weight due to tumor cell growth and increased the mean survival time of the tumor-bearing mice as compared to the untreated DLA control mice. The treatment of DLA-bearing mice brought down the Alanine Aminotransferase (ALAT, Aspartate Aminotransferase (ASAT, and alkaline phosphatase to normal levels. The extract decreased the levels of hepatic lipid peroxidation and increased the levels of hepatic antioxidants Glutathione, Superoxide Dismutase (SOD, and catalase. All the changes observed with AMEE treatment were dose dependent. Conclusion: The hydroalcoholic extract of A. marmelos exhibits strong antitumor and antioxidant activities in DLA-bearing mice.

  4. Effect of fast electrons and menadione on the structural and functional status of Ehrlich ascites tumor cells at early periods following irradiation

    International Nuclear Information System (INIS)

    Irradiation of Ehrlich ascites tumor cells stimulates oxygen consumption, and menadione supresses cell respiration. The combined effect of the two factors produces an additional, in comparison with the effect of menadione alone, inhibition of the rate of oxygen consumption by cells. There is an additive effect of radiation and menadione with regard to the level of cell thiols and interphase cell death

  7. Changes in energy metabolism following roentgen irradiation of in vivo growing Ehrlich ascites tumour cells studied by 31P magnetic resonance spectroscopy

    International Nuclear Information System (INIS)

    The energy metabolism in Ehrlich ascites tumour cells following in vivo irradiation of a dose of 5.0 Gy was studied in vitro in their ascites fluid up to 48 hours using 31P magnetic resonance spectroscopy measuring ATP, ADP and inorganic phosphate (Psub(i)). The results are also related to radiation induced changes in cell cycle composition. ATP was reduced by more than 50 per cent 20 to 24 hours after irradiation but normalized at 48 hours. ADP was reduced to about half the normal level 24 to 48 hours after irradiation. When the ATP and ADP had reduced levels, the inorganic phosphate increased correspondingly. Addition of glucose to the ascites cell suspension at the time of minimum ATP level immediately raised the ATP:Psub(i) ratio. Since the glucose concentrations in blood and in ascites fluid following irradiation were also reduced, lack of glucose for energy production might have been a major contributing factor for the reduced ATP production.

    Ascites is a major cause of mortality and morbidity in modern broiler production. Reduction of early growth, followed by compensatory gain, seems a practical and viable method to minimize losses caused by ascites. An experiment was conducted to determine if early feed restriction can reduce the incidence of ascites in broilers exposed to cool temperatures. Ross 308 cockerels (N=180) were assigned to 5 diet treatments and 2 temperature regimes, with 3 replicate pens of 6 birds per treatment and temperature. A standard grower diet was diluted by adding rice hulls at 0, 15, 30, 45, and 60% by weight from 7 to 14 d of age. On d 21 through 42, the temperature was maintained at 20 to 25°C (thermoneutral), or at 11 to 15°C (cool). Broilers exposed to cool temperatures developed higher right ventricle (RV) to total ventricle (TV) and RV to BW ratios, increased plasma triiodothyronine (T3) and thyroxine (T4) concentrations, and elevated blood values for hemoglobin concentration, mean cell volume, and hematocrit (Pascites. Diluting the feed with rice hulls from d 7 to 14 resulted in proportional reductions in BW by d 14 (P0.1). Exposure to cool temperatures increased key indices of ascites susceptibility, and these preascitic changes were partially prevented by diluting the feed to reduce growth performance. PMID:26217021

    Two experiments were conducted to evaluate the effects of early feed restriction on lipid peroxidation, pulmonary vascular remodelling and ascites incidence in broilers under normal and low ambient temperature. In experiment 1, the restricted birds were fed 8h per day either from 7 to 14 d or from 7 to 21 d, while the controlled birds were fed ad libitum. In experiment 2, the restricted birds were fed 80 or 60% of the previous 24-h feed consumption of full-fed controls for 7 d from 7 to 14 d. On d 14, half of the birds in each treatment both in experiment 1 and experiment 2 were exposed to low ambient temperature to induce ascites. Body weight and feed conversion ratio were measured weekly. The incidences of ascites and other disease were recorded to determine ascites morbidity and total mortality. Blood samples were taken on d 14, 21, 28, 35 and 42 to measure the plasma malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px). On d 42, samples were taken to determine the right/total ventricular weight ratio (RV/TV), vessel wall area/vessel total area ratio (WA/TA) and mean media thickness in pulmonary arterioles (mMTPA). Low-temperature treatment increased plasma MDA concentration. When broilers were exposed to a cool environment for 3 weeks, plasma SOD and GSH-Px activity were decreased compared with normal-temperature chicks. RV/TV, WA/TA and mMTPA on d 42 were increased in birds exposed to cold, consistent with the increased pulmonary hypertension and ascites morbidity. Early feed restriction markedly decreased plasma MDA concentration. The plasma SOD and GSH-Px activity of feed-restricted birds were markedly higher than those fed ad libitum on d 35 and d 42. All early feed restriction treatments reduced ascites morbidity and total mortality. On d 42, the RV/TV, WA/TA and mMTPA of feed-restricted broilers were lower than that of the ad libitum-fed broilers. The results suggested that early feed restriction alleviated the lipid

    Full Text Available Abstract Introduction Advanced abdominal (extrauterine pregnancy is a rare condition with high maternal and fetal morbidity and mortality. Because the placentation in advanced abdominal pregnancy is presumed to be inadequate, advanced abdominal pregnancy can be complicated by pre-eclampsia, which is another condition with high maternal and perinatal morbidity and mortality. Diagnosis and management of advanced abdominal pregnancy is difficult. Case presentation We present the case of a 33-year-old African woman in her first pregnancy who had a full-term advanced abdominal pregnancy and developed gross ascites post-operatively. The patient was successfully managed; both the patient and her baby are apparently doing well. Conclusion Because most diagnoses of advanced abdominal pregnancy are missed pre-operatively, even with the use of sonography, the cornerstones of successful management seem to be quick intra-operative recognition, surgical skill, ready access to blood products, meticulous post-operative care and thorough assessment of the newborn.

  12. Protective effect of pantothenic acid and related compounds against permeabilization of Ehrlich ascites tumour cells by digitonin.

    Preincubation of Ehrlich ascites tumour cells with millimolar concentrations of pantothenic acid, pantothenol or pantethine, but not with homopantothenic acid, at 22 degrees C or 32 degrees C, but not at 0 degrees C, makes the plasma membrane more resistant to the damaging effect of submillimolar concentrations of digitonin. It is proposed that this increased resistance is due to the increased rate of cholesterol biosynthesis. In fact, incorporation of [14C]acetate into cholesterol is by 45% increased in the cells preincubated with pantothenic acid; this probably reflects elevation of the content of CoA in such cells [Slyshenkov, V.S., Rakowska, M., Moiseenok, A.G. & Wojtczak, L.

    Full Text Available BACKGROUND: Rifaximin is a non-absorbable antibiotic used to prevent relapses of hepatic encephalopathy which may also be a candidate for prophylaxis of spontaneous bacterial peritonitis (SBP. AIM: To detect the impact of rifaximin on the occurrence and characteristics of SBP. METHODS: We prospectively studied all hospitalized patients that underwent a diagnostic paracentesis in our department from March 2012 to April 2013 for SBP and recorded all clinical data including type of SBP prophylaxis, prior use of rifaximin, concomitant complications of cirrhosis, as well as laboratory results and bacteriological findings. Patients were divided into the following three groups: no antibiotic prophylaxis, prophylaxis with rifaximin or with systemically absorbed antibiotic prophylaxis. RESULTS: Our study cohort comprised 152 patients with advanced liver cirrhosis, 32 of whom developed SBP during the study period. As expected, our study groups differed regarding a history of hepatic encephalopathy and SBP before inclusion into the study. None of the 17 patients on systemic antibiotic prophylaxis developed SBP while 8/27 patients on rifaximin and 24/108 without prophylaxis had SBP (p = 0.02 and p = 0.04 versus systemic antibiotics, respectively. In general, episodes of SBP were similar for patients treated with rifaximin and those without any prophylaxis. However, Escherichia coli and enterococci were dominant in the ascites of patients without any prophylaxis, while mostly klebsiella species were recovered from the ascites samples in the rifaximin group. CONCLUSION: Rifaximin pretreatment did not lead to a reduction of SBP occurrence in hospitalized patients with advanced liver disease. However, the bacterial species causing SBP were changed by rifaximin.

    Cancerous cells secrete alpha-N-acetylgalactosaminidase (NaGalase) into the blood stream, resulting in deglycosylation of serum vitamin D3-binding protein (known as Gc protein), which is a precursor for macrophage activating factor (MAF). Incubation of Gc protein with immobilized beta-galactosidase and sialidase generates the most potent macrophage activating factor (designated GcMAF). Administration of GcMAF to cancer-bearing hosts can bypass the inactivated MAF precursor and act directly on macrophages for efficient activation. Therapeutic effects of GcMAF on Ehrlich ascites tumor-bearing mice were assessed by survival time and serum NaGalase activity, because serum NaGalase activity was proportional to tumor burden. A single administration of GcMAF (100 pg/mouse) to eight mice on the same day after transplantation of the tumor (5 x 10(5) cells) showed a mean survival time of 21 +/- 3 days for seven mice, with one mouse surviving more than 60 days, whereas tumor-bearing controls had a mean survival time of 13 +/- 2 days. Six of the eight mice that received two GcMAF administrations, at Day 0 and Day 4 after transplantation, survived up to 31 +/- 4 days whereas, the remaining two mice survived for more than 60 days. Further, six of the eight mice that received three GcMAF administrations with 4-day intervals showed an extended survival of at least 60 days, and serum NaGalase levels were as low as those of control mice throughout the survival period. The cure with subthreshold GcMAF-treatments (administered once or twice) of tumor-bearing mice appeared to be a consequence of sustained macrophage activation by inflammation resulting from the macrophage-mediated tumoricidal process. Therefore, a protracted macrophage activation induced by a few administrations of minute amounts of GcMAF eradicated the murine ascites tumor. PMID:9893164

    We tested the hypothesis that poultry by-product meal would produce a thermogenic response (an increased requirement for oxygen) resulting in an increased incidence of pulmonary hypertension with right ventricular failure and ascites in commercial broiler chickens. Four treatment groups, each with three replicates of 40 chicks, were fed a commercial broiler starter to day 21, grower to day 35, and the following experimental diets after day 35: group 1, commercial chicken broiler finisher; group 2, commercial chicken broiler finisher with poultry by-product meal added to replace part of the soyabean meal; group 3, commercial chicken broiler finisher with poultry fat added to replace the animal-vegetable (AV) fat; group 4, commercial chicken broiler finisher with both poultry by-product meal and poultry fat added to replace soyabean meal and AV fat. On day 35, pen temperature was reduced to 15°C, and on day 42 to 12°C. Mortality from ascites between days 35 and 56 was 11(9%) in group 2, 5(4%) in group 4 and 3(2.5%) in groups 1 and 3 The incidence of pulmonary hypertension, as measured by an increased right ventricle: total ventricle (RV:TV) ratio (RV:TV > 0.249) at processing on day 57, was higher in the groups receiving poultry by-product and poultry fat: 27(22.5%) in group 2, 26(21.7%) in group 3, and 20(16.7%) in group 4 compared to that of the controls 12(10%).

    In recent few years, there have been some attempts to find a reliable indicator trait as a selection criterion against susceptibility to ascites syndrome (AS). Blood parameters were of great interest as they could be measured in live animals without implementing an ascites-inducing challenge (AIC). In this work, the suitability of some blood parameters was evaluated for diagnosing AS-susceptible chicks in later steps of the disease in trial 1 as well as their early predictive ability in trial 2. In the first trial, one hundred 1-day-old chicks from two pure broiler lines namely S1 and S2 and, in the second trial, 226 1-day-old chicks from line S2 were subjected to AIC. Saline drinking water (1200 mg/l) and lower-than-standard ambient temperatures were the implemented AICs in trials 1 and 2 respectively. The blood parameters including pH, partial pressure of O2 (pO2 ), partial pressure of CO2 (pCO2 ), bicarbonate ion concentration (BIC), percentage of haematocrit (HCT) and saturated haemoglobin (SaO2 ) were measured twice per each bird at days 28 and 35 in trial 1 and once in trial 2 at day 21. The results of the first trial revealed that in line S2 some of the blood parameters differed significantly between the ascitic and non-ascitic groups following exposure to AIC. In this line, the incidence of AS was accompanied by a lower pO2 , SaO2 and BIC, while with higher pCO2 and HCT values. In the second trial, however, although almost all of the parameters showed meaningful differences between the ascitic and non-ascitic broilers, only mean difference of BIC parameter was statistically significant. The general conclusion of this study is that the blood parameters can somewhat have diagnostic ability in the condition in which the AIC is already present, whereas the results did not approve their usefulness as early predictors of AS.

    Nitric oxide (NO) is a potent pulmonary vasodilator that modulates the pulmonary vasoconstriction and pulmonary hypertension (PH) triggered by bacterial lipopolysaccharide (LPS) in broilers. The amplitude and duration of the LPS-induced PH are markedly enhanced following pretreatment with N(omega)-nitro-L-arginine methyl ester (L-NAME), which inhibits NO synthesis by both the constitutive (endothelial) and inducible (inflammatory) forms of nitric oxide synthase (eNOS and iNOS, respectively). In the present study L-NAME and the selective iNOS inhibitor aminoguanidine (AG) were administered to differentiate between iNOS and eNOS as the primary source of NO that attenuates the pulmonary vascular response to LPS. Clinically healthy male progeny from ascites-susceptible and ascites-resistant lines were anesthetized, and their pulmonary artery was cannulated. The initial pulmonary arterial pressure (PAP) was recorded, then the broilers either remained untreated (control group) or were injected i.v. with AG. Ten minutes later all birds received an i.v. injection of LPS, followed 40 min later by an i.v. injection of L-NAME. When compared with untreated controls, AG neither increased the baseline PAP nor did it increase or prolong the PH response to LPS. The ascites-susceptible broilers maintained a higher PAP than the ascites-resistant broilers throughout the experiment, and the ascites-resistant broilers exhibited greater relative increases in PAP in response to LPS than did the ascites-susceptible broilers. Within 40 min after the LPS injection, PAP subsided to a level that did not differ from the respective preinjection value for each line. Injecting L-NAME reversed the decline in PAP, and within 5 min PAP returned to hypertensive levels approaching the maximum peak PH response to LPS. The absence of any impact of AG coupled with the profound response to L-NAME indicates that NO synthesized by eNOS rather than iNOS likely modulated the acute (within 1 h) PH elicited by

    The authors found in an earlier study that Phyllanthus amarus extract could significantly inhibit the solid and ascites tumor development in mice induced by Dalton's lymphoma ascites (DLA) cells. In the present study, the apoptotic effects of P. amarus against DLA cells in culture was evaluated. P. amarus produced significant reduction in cell viability as determined by the MTT assay. It also induces the formation of apoptotic bodies with characteristic features like plasma membrane invagination, elongation, fragmentation, and chromatin condensation. P. amarus at concentrations of 100 and 200 microg/mL is shown to induce DNA fragmentation. Gene expression analysis reveals that P. amarus induces the expression of caspase-3 and inhibits the expression of Bcl-2, which is an antiapoptotic protein. So the present study provides some insights into the possible mechanism by which P. amarus brings about apoptosis and growth inhibition in DLA cells. PMID:19223368

    A method for studying cells based on low-angle light scattering was applied to cell volume and cell signaling studies on Ehrlich ascite tumor cells (EATC). Changes in the volume of EATC were measured in hypotonic medium, as well as after activation with exogenous ATP, ionomycin and thimerosal. Increase of [Ca2+]i under ATP and ionomycin action induced reversible changes of cell volume: fast shrinking was followed by swelling. Thimerosal caused a reversible change in EATC volume with high ampl...

    Full Text Available Purpose: Monoclonal antibodies are potentially powerful tools used in biomedical research, diagnosis, and treatment of infectious diseases and cancers. The monoclonal antibody against Human IgA can be used as a diagnostic application to detect infectious diseases. The aim of this study was to improve an appropriate protocol for large-scale production of mAbs against IgA. Methods: For large-scale production of the monoclonal antibody, hybridoma cells that produce monoclonal antibodies against Human IgA were injected intraperitoneally into Balb/c mice that were previously primed with 0.5 ml Pristane. After ten days, ascitic fluid was harvested from the peritoneum of each mouse. The ELISA method was carried out for evaluation of the titration of produced mAbs. The ascitic fluid was investigated in terms of class and subclass by a mouse mAb isotyping kit. MAb was purified from the ascitic fluid by ion exchange chromatography. The purity of the monoclonal antibody was confirmed by SDS-PAGE, and the purified monoclonal antibody was conjugated with HRP. Results: Monoclonal antibodies with high specificity and sensitivity against Human IgA were prepared by hybridoma technology. The subclass of antibody was IgG1 and its light chain was the kappa type. Conclusion: This conjugated monoclonal antibody could have applications in designing ELISA kits in order to diagnose different infectious diseases such as toxoplasmosis and H. Pylori.

    Water accumulation in the interstitium (edema) and the peritoneum (ascites) of nephrotic patients is classically thought to stem from the prevailing low plasma albumin concentration and the decreased transcapillary oncotic pressure gradient. However, several clinical and experimental observations suggest that it might also stem from changes in capillary permeability. We addressed this hypothesis by studying the peritoneum permeability of rats with puromycin aminonucleoside-induced nephrotic syndrome. The peritoneum of puromycin aminonucleoside rats displayed an increase in the water filtration coefficient of paracellular and transcellular pathways, and a decrease in the reflection coefficient to proteins. It also displayed oxidative stress and subsequent activation of NF-κB. Scavenging of reactive oxygen species and inhibition of NF-κB prevented the changes in the water permeability and reflection coefficient to proteins and reduced the volume of ascites by over 50%. Changes in water permeability were associated with the overexpression of the water channel aquaporin 1, which was prevented by reactive oxygen species scavenging and inhibition of NF-κB. In conclusion, nephrotic syndrome is associated with an increased filtration coefficient of the peritoneum and a decreased reflection coefficient to proteins. These changes, which account for over half of ascite volume, are triggered by oxidative stress and subsequent activation of NF-κB. PMID:27033704

    Full Text Available Abstract Background Although the WHO guideline for the management of dengue fever considers the presence of ascites or pleural effusions in the diagnosis of DSS, it does not emphasize the importance of their presence when selecting fluids for resuscitation. Case presentation We highlight three patients with DSS who received boluses of crystalloids on priority basis as recommended by WHO guidelines during resuscitation. All three patients had varying degrees of third space fluid loss (ascites and pleural effusions at the time of development of DSS. Ascites and pleural effusions were detected in all 3 patients at the time of shock irrespective of whether iv fluids were given or not. All three patients had documented liver involvement at the time of shock evidenced by elevation of AST (4800 iu/L, 5000 iu/L and 1960 iu/L. One patient who had profound shock died 6 hours after admission with evidence of acute pulmonary oedema in the convalescence phase. All of them needed CPAP ventilator support and potent diuretics. Conclusions We therefore feel that resuscitation of patients with DSS who already have third space fluid accumulation with crystalloid boluses on priority basis may contribute to recovery phase pulmonary oedema.

    The objective of this study was to investigate the effects of L-carnitine on growth performance, organ weight, biochemical parameters of blood, heart and liver, and ascites susceptibility of broilers at different ages reared under a low-temperature environment. A total of 420 1-d-old male Ross 308 broilers were randomly assigned to two dietary treatments with fifteen replicates of fourteen broilers each. Treatment diets consisted of L-carnitine supplementation at levels of 0 and 100 mg/kg. At 11-d of age, low temperature stress was used to increase ascites susceptibility. Blood, heart and liver samples were collected at different ages for analysis of boichemical parameters. The results showed that, there was no significant difference in growth performance with L-carnitine supplementation, but the mortality due to ascites was significantly decreased. Dietary L-carnitine supplementation significantly reduced heart index (HI) and ascites heart index (AHI) on d 21, lung index (LUI) on d 35 and liver index (LI) on d 42. The broilers fed diets containing L-carnitine had significantly lower red blood cell counts (RBC), hemoglobin (HGB) concentration and hematocrit (HCT) on d 42. Dietary L-carnitine supplementation significantly reduced malondialdehyde (MDA) content of heart tissue on d 21 and 35, and significantly increased total superoxide dismutase (T-SOD) and Glutathione peroxidase (GSH-Px) activity of the heart on d 21 and 42. L-carnitine supplementation significantly reduced serum triglyceride (TG) content on d 28 and 35 and serum glucose (GLU) on d 35 and 42, and significantly increased serum total protein (TP) and globulin (GLO) content on d 42. L-carnitine supplementation significantly enhanced liver succinodehydrogenase (SDH), malic dehydrogenase (MDH) and Na(+)-K(+)-ATPase activity on d 28, and tended to reduce the lactic acid (LD) level of liver on d 35 (p = 0.06). L-carnitine supplementation significantly reduced serum uric acid (UA) content on d 28, 35 and 42

    Epidemiological and experimental data indicate that high body fat or high dietary fat can be ascribed to the induction of human cancers. Increased level of products of lipid peroxidation and cholesterol-enriched lipid domains in the plasma membrane can favorthe malignant transformation of cells. An effective chemopreventive agent with hypolipaedemic effect will be worthwhile to intervene early in the process of carcinogenesis to eliminate the pre-malignant cells. Apoptotic promoting and antitumor activities of a HMG-Co A reductase inhibitor, atorvatstain were investigated. The antitumor activity was evaluated using Daltons' Lymphoma Ascites (DLA) cell line transplanted ascites tumor model in mice. Proapoptotic activity was evaluated in DLA cell line induced ascites animals after the treatment of atorvastatin (4 and 16 mg/kg, i.p). Apoptosis was analyzed morphologically by staining with giemsa and biochemically by observing the laddering of DNA in agarose gel electrophoresis. In vitro short term cytotoxic activity of atorvatstain was studied by trypan blue dye exclusion method. Doxorubicin was used as the reference standard. Atorvastatin significantly (P growth at 16 mg/kg body wt (i.p). The percent increase in life span (%ILS) in the 16 mg/kg treated group was 41.1%. Single dose of atorvastatin (16 mg/kg body wt) was also effective to promote the apoptosis of DLA cells in the ascites tumor bearing mice that was evident from the multiple fragmentation of DNA in agarose gel electrophoresis. Further the morphological analysis of DLA cells aspirated from the atorvastatin treated ascites tumor bearing animals showed 36.34 +/- 6.78% apoptotic cells compared to the control animals (10.50 +/- 3.53%). Concentration of atorvastatin required for the 50% of the cytotoxicity was 30 +/- 2 microg/ml. Results of the study concluded that the antitumor activity of atorvastatin may be due to its proapoptotic and cytotoxic activities. These pleiotropic activities of the hypolipedaemic

  9. Effect of plumbagin on the radiation induced cytogenetic and cell cycle changes in mouse Ehrlich ascites carcinoma in vivo

    International Nuclear Information System (INIS)

    The effect of plumbagin, a naphthoquinone from the roots of the Indian medicinal plant Plumbago rosea, and cobalt-60 gamma radiation was studied on Ehrlich ascites carcinoma in vivo, taking cytogenetic damage and cell cycle changes as experimental endpoints. Plumbagin (5 mg/kg body wt, Pl) administered intraperitoneally produced a significant increase in the percentage of S-phase as well as G2-M cells with a corresponding decrease in the G1 phase at different post-treatment times. Radiation (7.5 Gy, RT) alone produced the classical G2 block at 1 hr, which persisted with a continuous increase throughout the post-treatment observation period. The combination treatment produced a similar effect as that of RT on G2-M cells, but its effect on the G1 phase was more pronounced than the latter. While Pl treatment produced a small increase in the percentage of labelled S-phase cells, combination treatment significantly reduced the labelled S-phase cells with a corresponding increase in the unlabelled fraction. Drug or radiation alone significantly increased micronuclei induction at various post-treatment times and the combination of the two further enhanced this effect additively. The mechanism of interaction of Pl with radiation in bringing about this effect is not clear. (author)

    Advanced ovarian cancer (AOC) is one of the leading lethal gynecological cancers in developed countries. Based on the important role of angiogenesis in ovarian cancer oncogenesis and expansion, we hypothesized that the development of an "angiogenic signature" might be helpful in prediction of prognosis and efficacy of anti-angiogenic therapies in this disease. Sixty-nine samples of ascitic fluid- 35 from platinum sensitive and 34 from platinum resistant patients managed with cytoreductive surgery and 1st-line carboplatin-based chemotherapy- were analyzed using the Proteome ProfilerTM Human Angiogenesis Array Kit, screening for the presence of 55 soluble angiogenesis-related factors. A protein profile based on the expression of a subset of 25 factors could accurately separate resistant from sensitive patients with a success rate of approximately 90%. The protein profile corresponding to the "sensitive" subset was associated with significantly longer PFS (8 [95% Confidence Interval {CI}: 8-9] vs. 20 months [95% CI: 15-28]; Hazard ratio {HR}: 8.3, pAOC, which can be used, after appropriate validation, as a prognostic marker and a tool for selection for anti-angiogenic therapies.

    Irradiation of Ehrlich ascites carcinoma (EAC) cells in the presence of pheomelanin, i.e., red hair melanin (RHM), has been reported to produce extensive cell lysis. Irradiation in the presence of eumelanin, i.e., black hair melanin (BHM), or irradiation in the absence of either type of melanin did not produce this effect. We observed that RHM particles penetrated the cell membrane without apparent structural damage to the cell or the cell membrane. Irradiation of the cells in the absence of melanin did not produce any changes in the ultrastructure of the cells. Incubation of the cells in the dark in the presence of RHM produced only minor structural, mainly cytoplasmic changes. Irradiation of the cells in the presence of RHM produced extensive ultrastructural changes prior to complete cell lysis; these changes were more severe than the effects of incubation of the cells in the dark in the presence of RHM. When the cells incubated in the dark or irradiated in the presence of latex particles or either one of the eumelanins particles, viz. BHM or synthetic dopa melanin, these particles did not penetrate into the cells or produce any ultrastructural changes. These particles were in fact not even ingested by the cells.

    Diabetes mellitus is a multifunctional disorder with several causes and multiple consequences. Nutraceuticals play a vital role in ameliorating diabetic condition. The stems of the plant, Tinospora cordifolia (T. cordifolia) are often used in Ayurvedic medicine for the management of diabetes. Earlier studies have shown that T. cordifolia to be a potent antidiabetic plant material by virtue of being rich in nutraceuticals. In the present study we were interested to know if, T. cordifolia stem extracts are able to promote glucose uptake through glucose transporters, 1 (GLUT1) and 3 (GLUT3), which are responsible for basal glucose uptake. Hence, Ehrlich ascites tumor (EAT) cells were chosen as a model which harbours both GLUT1 and GLUT3 and glucose uptake was measured using a fluorescent analog 2-[N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl)amino]-2-deoxy-D-glucose (2-NBDG). Serially, solvent extracted T. cordifolia stems, especially water, ethanol and methanol extracts showed glucose uptake activity. Uptake was stimulated in a dose dependent manner at dosages of 1-100 μg. Glucose-stimulating activity does not seem to be solely due to polyphenol content since methanol extract, with high amount of polyphenol content (9.5 ± 0.1 g kg(-1)), did not stimulate higher glucose uptake activity when compared to water extract.

    Full Text Available Objective : The main objective of the present study was to explore the antitumor activity of the ethyl acetate extract of the Alternanthera brasiliana (EAAB and its antioxidant status against Ehrlich ascites carcinoma (EAC in Swiss albino mice. Materials and Methods: Based on the preliminary in vitro cytotoxicity studies, EAAB was selected for anti-tumor and antioxidant effects. Anticancer activity of EAAB was evaluated against EAC in Swiss albino mice at the doses of 200 and 400 mg/kg. EAAB was administered for 14 consecutive days after induction of cancer. After 24 h of the last dose and 18 h of fasting, half of the mice were sacrificed and rest were kept alive for assessing any increase in life span. The antitumor effect of EAAB was assessed by evaluating tumor volume, viable and nonviable tumor cell count, tumor weight, hematological and biochemical parameters of EAC bearing host. Furthermore, the antioxidant and histopathological parameters were evaluated. Results: EAAB treatment has shown significant decrease in tumor volume, viable cell count, tumor weight and elevated the life span of EAC tumor bearing mice in a dose dependent manner. In hematological profile count of RBC, hemoglobin, and WBC were found reverted to normal. EAAB also significantly decreased the levels of lipid peroxidation and significantly increased the levels of GSH, SOD and Catalase. Conclusion: From the above results it may be concluded that EAAB has potent dose dependent antitumor activity and is comparable to that of 5-flourouracil.

    An experiment was carried out to investigate the effects of ascites syndrome (AS) on the growth performance and availability of dietary energy and nutrients in broilers.One hundred and twenty one-day-old avian broilers were randomly allotted into two groups (control group and test group)with six replications of ten birds.In the test group,the addition of 3,3,5-triiodothyronine (T3,1.5 mg/kg diet) and low ambient temperature (LAT) were used to induce AS.Results showed that T3 and LAT could successfully induce AS in broilers with an incidence rate of 66.7% and a mortality rate of 23.3%.Compared with the control,the bird growth performance of the test group was decreased (P<0.05) and heart index was increased (P<0.05).For the test group,the availability of dietary energy (P<0.01),crude fat (P<0.01),crude protein (P<0.05),and most amino acids in the second week were lower compared with the control group.Results showed that the low availability of energy and nutrients and the poor growth resulted from the high AS incidence rate.

  15. Ultrastructural changes produced in Ehrlich ascites carcinoma cells by ultraviolet-visible radiation in the presence of melanins

    International Nuclear Information System (INIS)

    Irradiation of Ehrlich ascites carcinoma (EAC) cells in the presence of pheomelanin, i.e., red hair melanin (RHM), has been reported to produce extensive cell lysis. Irradiation in the presence of eumelanin, i.e., black hair melanin (BHM), or irradiation in the absence of either type of melanin did not produce this effect. We observed that RHM particles penetrated the cell membrane without apparent structural damage to the cell or the cell membrane. Irradiation of the cells in the absence of melanin did not produce any changes in the ultrastructure of the cells. Incubation of the cells in the dark in the presence of RHM produced only minor structural, mainly cytoplasmic changes. Irradiation of the cells in the presence of RHM produced extensive ultrastructural changes prior to complete cell lysis; these changes were more severe than the effects of incubation of the cells in the dark in the presence of RHM. When the cells incubated in the dark or irradiated in the presence of latex particles or either one of the eumelanins particles, viz. BHM or synthetic dopa melanin, these particles did not penetrate into the cells or produce any ultrastructural changes. These particles were in fact not even ingested by the cells

    SCID mice were inoculated with five human-mouse heterohybridomas derived by fusion of human lymph node lymphocytes from lung cancer patients with murine myeloma cells or human-mouse heteromyeloma cells, and the production of their human monoclonal antibodies (MAb) in the mouse ascites was investigated. In a comparison of the effects of pretreatment by i.p. (intraperitoneal) injection of pristane and anti-asialo GM1 serum on the antibody production of three of the hybridomas, pristane pretreatment resulted in substantial antibody production by all three, and pretreatment with anti-asialo GM1 serum resulted in similar or slightly lower levels of antibody production by two of the hybridomas but none by the third. In a second series of experiments using four of the hybridomas with pristane pretreatment, the co-injection of either penicillin G and streptomycin or kanamycin together with the hybridoma at the time of i.p. inoculation resulted in enhanced MAb production by the two heterohybridomas that had been propagated in medium containing hypoxanthine-aminopterin-thymidine (HAT) but not by the two that had been propagated in HAT-free medium.

    In this study we tested the hypothesis that excess dietary salt produces an expansion of extracellular fluid volume which may be associated with pulmonary hypertension-induced right ventricular failure in chickens with rapid growth rates. One-week-old broiler and White Leghorn chickens were given 0.5% salt in their drinking water for three weeks. Saline water had a minimal effect on White Leghorns. The hypothesis appears to be correct since salt-treatment in broilers resulted in up to 30% expansion in blood volume and there was 50% mortality from pulmonary hypertension-induced right ventricular failure and ascites. There was marked (up to 88% in some broilers) right ventricular hypertrophy, an indicator of pulmonary hypertension. There was less left ventricular hypertrophy as shown by an increase in the ratio of the right to total ventricle weight. There was up to 32% decrease in growth rate. There was renal hypertrophy in the salt-treated birds as shown by a higher kidney to body weight ratio. PMID:8490804

    The objective of this study was to assess the effects of dietary supplementation with lipoic acid (LA) on broilers maintained at 2235 m above sea level with high risk to develop ascites syndrome (AS). A total of 2040 chicks were fed under commercial conditions with water and specific diets ad libitum during 7 weeks in two consecutive experiments. Mortality and indicators of performance and oxidative stress were compared weekly in broilers fed a basal diet plus 0, 10, 20, or 40 parts/10(6) LA. The effects of LA at 40 parts/10(6) were also studied during the initial 3 weeks or the last 4 weeks of the production cycle. Diets supplemented with 40 parts/10(6) of LA during 7 weeks significantly improved feed conversion, decreased general mortality and mortality attributable to AS, and lowered thiobarbituric acid reactive substances and hydroxyl radicals in liver, and increased total glutathione pool. Smaller doses or shorter periods of exposure to LA were partially effective. In conclusion, LA under our experimental conditions has a prophylactic action in broilers with high risk to develop AS due to oxygen availability limitation. PMID:14676017

    Characteristics of multiple-drug resistance of rat ascites hepatoma AH66, a cell line induced by dimethylaminoazobenzene and established as a transplantable tumor, were compared with those of AH66F, a drug sensitive line obtained from AH66. The AH66 cell line was resistant to vinblastine, adriamycin, SN-38 an active form of camptothesine, etoposide, and clorambucil by 10-fold or more than the AH66F cell line. The resistance of AH66 cells to vinblastine, adriamycin, and SN-38 was closely related to P-glycoprotein overexpression in the plasma membrane, because the resistance was significantly inhibited by verapamil. AH66 cells contained much glutahione and had a high activity of glutathione S-transferase P-form (GST-P), compared with AH66F cells, and resistance to clorambucil was decreased by treatment with buthionine sulfoximine, an inhibitor of glutathione synthesis. AH66 cells have a similar topoisomerase I activity, but about 6 times lower topoisomerase II activity than AH66F cells. Therefore, the resistance to etoposide and a part of the resistance to adriamycin of AH66 cells seems to depend upon this low topoisomerase II activity. These results, show that the AH66 cell line has high multiple-drug resistance compared with the AH66F cell line, by several mechanisms. Consequently, the AH66 and AH66F cell lines are useful to study naturally acquired multiple-drug resistance of hepatomas. PMID:8702243

    腹水征的发生是遗传、营养、环境和饲养管理等多因素综合作用的结果.家禽育种者对肉鸡生长性状的高强度选育也给肉鸡带来解剖学和生理学的缺陷,对肉鸡的健康产生了负面影响.肉鸡快速生长时需氧量显著升高,而高的生长速度与氧气供需之间的不平衡,以及氧气供应功能的损伤刺激心血管等许多补偿机制的形成,最终引起腹水征的发生.肉鸡腹水征给肉鸡生产造成了严重的经济损失,因此,深入研究肉鸡腹水征的发病机理,进而采取有效的调控措施降低其发病率,对促进肉鸡产业的健康发展具有十分重要的意义.采用早期限饲、添加营养调控剂和加强饲养管理等措施可以有效地降低肉鸡腹水征的发生率.本文就肉鸡腹水征的影响因素、发病机理以及降低肉鸡腹水征发生的调控措施进行了综述.%Ascites is a multifactorial syndrome, which is caused by interactions among genetic, nutritional, en-vironmental and management factors. Forced selection for growth traits of chickens has resulted in some ana-tomical and physiological limitations, which have adverse effects on bird health. The fast growing broilers with a high metabolic rate need higher oxygen demand, but un-matching oxygen supply with rapid growth, and the impaired functions for oxygen supply stimulate the development of many compensatory mechanisms in cardiop-ulmonary systems, which, in turn, brings about ascites syndrome. Ascites causes important economic losses in poultry breeding industry. Therefore, further studying the pathogenesis of chicken ascites, and taking effective measures to reduce the ascites incidence are very important to the healthy development of chicken industry. Early feed restriction, supplementation of nutrition regulatory agents, and good management strategies can ef-fectively reduce the incidence of ascites. This article mainly summarized the influencing factors, pathogenesis

    Full Text Available Os programas de melhoramento genético de frangos de corte que buscam máxima velocidade de ganho de peso, alta eficiência alimentar, alta viabilidade, maior rendimento de carcaça e menor deposição de gordura podem desencadear algumas síndromes fisiológicas, dentre as quais destacam-se o estresse calórico, a morte súbita e a ascite. A ascite se enquadra no conceito das síndromes multifatoriais, uma vez que sua manifestação ocorre quando certos fatores genéticos e ambientais atuam em conjunto determinando o processo. As limitações anatômica e fisiológica da circulação sanguínea nos pulmões provocam a síndrome de hipertensão pulmonar (PHS; esta pode provocar grande acúmulo de fluido na cavidade abdominal, quadro este denominado de ascite. Ocorre redução da eficiência da circulação sangüínea, levando as aves à morte por hipóxia, predominantemente no período entre 30 e 40 dias de idade. Uma vez desencadeado o processo ascítico, a ave dificilmente é aproveitada no abate já que a mesma restringe o consumo de alimento, ganhando menos peso. Adicionalmente, a carcaça apresenta aumento do volume da cavidade abdominal e conseqüente congestão dos órgãos internos. A descrição da fisiologia, medidas de avaliação e perspectivas são apresentadas neste trabalho.Poultry genetic breeding programs which look for maximum weight gain, improved feed conversion, high viability, high carcass yield and low fat deposition may cause some physiologic syndromes, for example caloric stress, sudden death and ascites. Ascites is framed in concept of the multifactorial syndromes, once its manifestation happens when certain genetic and environment factors act together, determining the process. Anatomical and physiological limitations in blood circulation in the lungs give rise to pulmonary hypertension syndrome (PHS, producing great fluid accumulation in abdominal cavity, which is denominated ascites.

  2. Role of Ethanol Extract of Bidens Pilosa L. Against Ehrlich Ascites Carcinoma Bearing Mice Exposed to Gamma Radiation

    International Nuclear Information System (INIS)

    Bidens pilosa L. is one of the dominant families of plants contributing to medicinal species worldwide. The present study was performed to investigate the role of ethanolic extract of B. pilosa (BpE) against Ehrlich ascites carcinoma (EAC)-induced hepatic dysfunction in gamma irradiated mice. BpE was orally administered to mice for eight consecutive days at the dose of 250 mg/kg body weight (one day before and eight days after tumour inoculation). On the 3rd day of tumour inoculation, animals were exposed to whole body gamma radiation at dose of 6 Gy. The results obtained in the present study revealed that both EAC and/or gamma radiation induced liver biochemical and histopathological alterations. In vitro short term toxicity study, Bidens pilosa extract at different experimental dose levels increased the percentage of non-viable cell count. Gamma radiation and/or EAC induced oxidative stress, inflammation and biochemical alteration in liver function. The liver oxidative stress was manifested by increase in lipid peroxidation concomitant with decrease in glutathione and superoxide dismutase levels. Liver inflammation was manifested by increased levels of tumour necrosis factor-a (TNF-a), interlukin-2 (IL-2) and alteration in leukocyte count (LC). Biochemical alteration in liver function manifested by significant increase in liver transaminases (AST and ALT) and lactate dehydrogenase (LDH). Moreover, radiation and EAC induced liver oxidative stress and significant increase in caspase-3. In vivo studies showed that BpE restored the hepatic function profile in tumour bearing mice. Histopathological studies showed that EAC and radiation caused fatty degeneration, enlargement of liver cells nuclei and presence of necrosis. Treatment with BpE modulates most of the pathological alterations. It could be concluded that the hepato protective effect of BpE is related to its phyto chemical components, which were claimed to be the mechanism of hepatic protection.

    Full Text Available ABSTRACTThe aim of the current study was to determine the effects of low (33.3-36.7 ˚C, control (37.8-38.2 ˚C and high (38.9-40.0 ˚C eggshell temperatures (ESTs between days 10-18 of incubation on broiler performance and susceptibility to ascites. The effects of different ESTs on hatchling weight were significant. The highest residual yolk sac weight (7.7 g and relative yolk sac weight (18.7% were observed in high EST group, whereas the highest yolk-free body weight (36.22 g was obtained in the control group. Relative post-hatch heart weight was lower in the high EST group (0.64% compared with the control (0.84% and low (0.88% EST groups. At 6 weeks of age, body weights of broilers of the low, control, and high EST groups were 2172.6, 2543.9, 2282.6 g respectively. During the 6-week life span, the feed conversion ratio of broilers in the low (1.86 and high (1.83 EST groups was significantly worse than of those in the control EST group (1.68. Higher packed cell volume (PCV and red blood cell (RBC values were obtained in the high EST group relative to the other groups, whereas hemoglobin (Hb level was lower in the control group than in the others. The relative heart weights and right ventricular to total ventricular (RV:TV ratio for low, control, and high EST group were 0.46, 0.40, 0.37 g and 0.27, 0.28, 0.33% respectively. In conclusion, incubation length, yolk sac absorption, residual yolk sac weight, yolk-free BW, post-hatch performance, and heart, blood parameters, abdominal fluid accumulation at slaughter age are affected by changes in EST between incubation days 10 to 18.

    Ascites syndrome (AS) still has an unacceptably high incidence rate in both humans and animals although there have been many studies on AS. To continue our previous pathological and biochemical investigation on the underlying mechanisms of AS incidence in broiler chickens, cutting-edge technologies including RNA-seq and metabolimics were used by directly comparing AS chickens and healthy controls. The RNA-seq analysis in the liver identified 390 differentially expressed genes (DEGs), among which 212 genes were up-regulated and 178 genes were down-regulated in the AS group compared to the control. For the down-regulated DEGs, further gene ontology (GO) analysis suggested that lipid metabolism, cell differentiation, enzyme linked receptor protein signaling pathway and steroid biosynthesis pathway were significantly enriched. For up-regulated DEGs, the cholesterol metabolic process has the lowest p value (0.000966) of fold enrichment while the cholesterol biosynthetic process has the highest fold enrichment (46.67). The metabolomic analysis of serum revealed statistically significant changes in the concentrations of LysoPC(20 : 4), LysoPC(16 : 0), LysoPC(18 : 0), LysoPC(18 : 1), LysoPC(18 : 2), PC(14 : 1/20 : 1), PC(20 : 4/18 : 0), PC(14 : 1/22 : 1), dihydroxyacetone, indoleacrylic acid, ursodeoxycholic acid, l-valine, and l-tryptophan. The integrative analysis of transcriptome and metabolome indicated that two biological pathways of tryptophan biosynthesis and metabolism, and glycerophospholipid metabolism may contribute to the induction of AS in broilers. These findings have provided novel insights into our understanding of molecular mechanisms of AS incidence in broilers. PMID:25178933

    Experiments were carried out using various levels of sodium (Na+) from NaCl or NaHCO3 to determine: 1) the level of Na+ required to induce ascites alone or in combination with cold temperature and 2) the effect of Na+ on weight gain and fat deposition in broiler chickens. In experiment 1, there were no cases of ascites using levels of Na+, from NaCl at 0.14% to 0.44% in the feed from day 3 or using added Na+, from NaCl at 0.0% to 0.12% in the water from day 3 with a level of 0.14% in the feed. There was no significant difference in 21 or 42 day body weight, feed conversion, or right ventricle:total ventricle (RV:TV) ratio between treatment groups. Day 3 to 4 body weight gains were significantly increased in all treatment groups with added Na+ (p less than 0.01). In experiment 2, with levels of added Na+, from NaCl, at 0.0% to 0.12% in the water with a level of 0.20% in the feed there were two cases of ascites, one at day 7 and one at day 40 at the 0.12% level. There were no significant differences in body weight at days 21 or 42 or in the RV:TV ratios between groups. Feed conversions were improved (p less than 0.01) with the lowest and highest levels of Na+ and a significant increase in day 3 to 4 body weight gain, with increasing Na+ in all treatment groups, was observed.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1423057

  9. The influence of X radiation on the proliferation kinetics of Ehrlich ascites tumors of different ploidy (in vivo investigations following 500 ROD)

    International Nuclear Information System (INIS)

    The proliferation kinetics following a single irradiation (500 ROD) was investigated in the following work in two Ehrlich ascites tumors of different ploidy (diploid EAT and tetraploidy ELT). The H3 thymidine availiblity time hardly changed after irradiation, it was about 40 minutes as in untreated control tumours. The H3 thymidine incorporation rate, in contrast, was in reduced both tumours by about 75% of the value for the untreated control tumour. The H3 labelling index did not greatly deviate from the control vlues. In the investigation of the cell cycle in the %-labelled mitosis test and with the double labelling method, both tumours exhibited distinctly different behaviour: Whilst the tetraploid exhibited no considerable extension of the S-phase and the generation time changed only slightly, the doploid EAT showed an ectension of S-phase and generation time of about the factor 2. In further tests, after irradiating both ascites tumours, all counting showed a clearly slower cell multiplication was found compared to the untreated control tumour. Whilst this was especially due to a strangly increasing dealth rate with ELT, it was more likely the longer generation time at merely moderate death rate which can be assumed as inhibiting the proliferation in the case of EAT sub(dipl). The mitosis index exhibited a depression of over 5 hours for EATsub(dipl) and of over 20 hours for ELT. Here too a different behaviour can be seen for both tumours after irradiation. As a whole, the results obtained for the different ploidy ascites tumours after X-radiation are to be considered as expression of the individuality of various tumour cell strains. (orig./MG)

    1997-06-01

    Vitamin D3-binding protein (DBP; human DBP is known as Gc protein) is the precursor of macrophage activating factor (MAF). Treatment of mouse DBP with immobilized beta-galactosidase or treatment of human Gc protein with immobilized beta-galactosidase and sialidase generated a remarkably potent MAF, termed DBPMAF or GcMAF, respectively. The domain of Gc protein responsible for macrophage activation was cloned and enzymatically converted to the cloned MAF, designated CdMAF. In Ehrlich ascites tumor-bearing mice, tumor-specific serum alpha-N-acetylgalactosaminidase (NaGalase) activity increased linearly with time as the transplanted tumor cells grew in the peritoneal cavity. Therapeutic effects of DBPMAF, GcMAF, and CdMAF on mice bearing Ehrlich ascites tumor were assessed by survival time, the total tumor cell count in the peritoneal cavity, and serum NaGalase activity. Mice that received a single administration of DBPMAF or GcMAF (100 pg/mouse) on the same day after transplantation of tumor (1 x 10(5) cells) showed a mean survival time of 35 +/- 4 days, whereas tumor-bearing controls had a mean survival time of 16 +/- 2 days. When mice received the second DBPMAF or GcMAF administration at day 4, they survived more than 50 days. Mice that received two DBPMAF administrations, at days 4 and 8 after transplantation of 1 x 10(5) tumor cells, survived up to 32 +/- 4 days. At day 4 posttransplantation, the total tumor cell count in the peritoneal cavity was approximately 5 x 10(5) cells. Mice that received two DBPMAF administrations, at days 0 and 4 after transplantation of 5 x 10(5) tumor cells, also survived up to 32 +/- 4 days, while control mice that received the 5 x 10(5) ascites tumor cells only survived for 14 +/- 2 days. Four DBPMAF, GcMAF, or CdMAF administrations to mice transplanted with 5 x 10(5) Ehrlich ascites tumor cells with 4-day intervals showed an extended survival of at least 90 days and an insignificantly low serum NaGalase level between days 30 and 90

    A study was made of the influence of membrane-active agents with different mechanisms of action (quercetine, amyloride, valinomycine, and digitonine), that modify the transmembrane transfer of inorganic ions, on a modifying effect of a glucose loading in X-irradiated Ehrlich ascites tumor cells. The combination of digitonine with glucose increased the damaging effect of radiation on tumor cells by 1.8-2.2 times as compared to glucose alone. Merely insignificant changes in the radiomodyfying effect of glucose were observed when it was combined with other membrane-active agents

    Osmotic shrinkage of Ehrlich ascites tumor cells (EATC) elicited translocation of myosin II from the cytosol to the cortical region, and swelling elicits concentration of myosin II in the Golgi region. Rho kinase and p38 both appeared to be involved in shrinkage-induced myosin II reorganization. In...... effects on F-actin. The subsequent F-actin depolymerization, however, appeared MLCK- and PKC-dependent, and the initial swelling-induced F-actin depolymerization was MLCK-dependent; both effects were apparently secondary to kinase-mediated effects on cell volume changes. NHE1 in EATC is activated both by...

  16. On the action of radioprotective agents on the endogenous serotonin content and radiosensitivity of isolated Ehrlich ascites tumour and E. coli B. cells

    International Nuclear Information System (INIS)

    At a higher radioresistance level attained by incubation of isolated Ehrlich ascites tumour and E. coli B. cells with MEA or noradrenaline, the endogenous serotonin content of these cells was found to increase. The extent of radioresistance increase and the serotonin content of the cells were interrelated, i.e. washing the protector off cells decreased both the radioresistance and the content of endogenous serotonin. It is concluded that radioresistance of cells is connected with the content of biologically active substances (serotonin) that possess radioprotective action

    The rate of quenching by Ehrlich ascites cells of anionic 2,6-dimethoxy-p-semiquinone and ascorbyl free radicals is investigated as a function of cell concentration, the blocking of cell-surface sulfhydryl groups by N-ethylmaleimide, and the reduction of cell-surface charge by neuraminidase. The rate of quenching is found to be proportional to cell viability and to the number of free cell-surface sulfhydryl groups. The enzymatic action of neuraminidase results in an increase of the free radic...

  18. Effect of Egyptian Propolis Extract as an Adjuvant with Irradiated Cancer Vaccine against Ehrlich Ascites Carcinoma in Mice

    International Nuclear Information System (INIS)

    Propolis is a non-toxic natural substance with multiple pharmacological properties including anti-cancer and antioxidant. The objective of this study was to investigate the effect of Egyptian propolis extract (Prop) as an adjuvant co-injected with irradiated tumour cell lysate vaccine (Irr-V) against Ehrlich ascites carcinoma (EAC) in mice. Animals were divided into five equal groups (n=10). Control group. EAC group; injected with viable EAC (2x105/mouse) in the right thigh. EAC-Prop group; injected subcutaneously (Sc) with Prop (0.4 mg/ mouse) weekly for three times, then after 2 weeks mice were received EAC viable cells (the day of challenge). Irr-V group; vaccinated with irradiated EAC cell lysate weekly for three times at a dose of 0.2µl in the right thigh. Prop-Irr-V group; vaccinated as Irr-V group, and treated with Prop as EAC-Prop group. Two weeks post the last treatment; animals of groups 4 and 5 were challenged with normal viable EAC (2x105/mouse) in the opposite thigh. Results: The results revealed a decrease in red blood cells (RBC) count, haematocrite value (Hct) and haemoglobin content (Hb) and an increase in total leucocytes, absolute lymphocyte and neutrophil counts in EAC-bearing mice. Furthermore, oxidative stress identified by a decrease in glutathione (GSH) content and superoxide dismutase (SOD) activity associated with an increase in the content of advanced oxidation protein products (AOPP) and malondialdehyde (MDA) were recorded in the liver and blood tissues of EAC-bearing mice. Propolis, Irr-V as well as Irr-V-Prop treatment improved haematological toxicities and oxidative stress in EAC-bearing mice. However, improvement was more pronounced in Irr-V-Prop group and the cell viability assay, the tetrazolium dye;3-(4,5-dimethylthiazol-2-yl)-2,5-iphenyltetrazolium (MTT) showed a significant decrease in viable cells compared to each treatment alone. It could be concluded that Prop extract might be used as an adjuvant for irradiated cancer

  19. Expression of P-glycoprotein and multidrug resistance associated protein in Ehrlich ascites tumor cells after fractionated irradiation

    International Nuclear Information System (INIS)

    Purpose: To characterize irradiated murine tumor cells with respect to drug resistance, drug kinetics, and ATPase activity, and to evaluate the possible role of P-glycoprotein (PGP) and murine multidrug resistance associated protein (Mrp1) in the drug-resistant phenotype of these cells. Methods and Materials: Sensitive Ehrlich ascites tumor cells (EHR2) were in vitro exposed to fractionated irradiation (60 Gy). Western blot analysis was performed for determination of PGP and Mrp1, reverse transcriptase-polymerase chain reaction (RT-PCR) for determination of mdr1a + b mRNA, and semiquantitative RT-PCR for Mrp1 mRNA. The clonogenic assay was applied to investigate sensitivity, whereas the steady-state drug accumulation of daunorubicin (DNR), 3H-vincristine (VCR), and 3H-etoposide (VP16) was measured by spectrofluorometry and scintillation counting, respectively. For determining of ATPase activity, the release of inorganic phosphate from ATP was quantified using a colorimetric method. Results: Compared with EHR2, the irradiated cell line EHR2/irr showed increased expression of PGP (threefold), Mrp1 (eightfold), and Mrp1 mRNA (sixfold), and a slight reduction of mdr1b mRNA, whereas mdr1a was present in EHR2 but could not be detected in EHR2/irr. EHR2/irr developed sixfold resistance to VP16, twofold resistance to vincristine, but remained sensitive to DNR. Addition of the PGP inhibitor, verapamil (VER) or depletion of glutathione by buthionine sulfoximine (BSO) partly reversed the resistance in EHR2/irr. In EHR2/irr, the steady-state accumulation of 3H-VCR and 3H-VP16 was significantly decreased as compared with EHR2, whereas the accumulation of DNR was unchanged. The ATPase activity of plasma membrane vesicles prepared from EHR2/irr cells was similar to that of wild-type EHR2 cells. The ATPase activity was neither stimulated by vinblastine nor VER. Conclusion: Irradiation induced a multidrug-resistant phenotype in sensitive tumor cells. This phenotype was

    Full Text Available Radiation therapy aims to kill cancer cells with a minimum of normal tissue exposure. In an attempt to define the molecular and biochemical changes associated with exposure to radiotherapy, the objective of the present study is to explore the effect of gamma (γ irradiation on nuclear factor, erythroid 2 (NFE2, P53, stromelysin-1 (matrix metalloproteinase-3 (MMP3, BCL-2 and BAX genes expression in Ehrlich ascites carcinoma (EAC bearing mice. Various biochemical parameters such as liver function, H2O2, B% and T% lymphocytes, total antioxidants and MDA were investigated to evaluate their usefulness as possible during cancer treatment with radiotherapy. Rats were irradiated with a single whole body Cobalt 60-gamma radiation dose of 0.5 Gy. Sixty-four female mice, weighing 20–25 g were used in this study and divided into three main groups. The first group served as control group, while the second were injected intraperitoneally with EAC then was subdivided into two groups, II A and II B. The latter one (group II B, the animals were exposed to a single dose of 0.5 Gy whole body γ irradiation. The third main group, were irradiated with a single dose of 0.5 Gy whole body γ irradiation. Blood and liver tissue samples were collected at 4, 24 and 96 h post-irradiation. The gene expression levels in the livers of animals from each exposure group were compared individually with that of pooled sham-irradiated animals. MMP3 and NFE2 were overexpressed in liver samples of EAC group post 4, 24 and 96 h of γ irradiation (IIB. On the other hand, P53 and BCL-2 genes were downregulated by using RT-PCR analysis post 4, 24 and 96 h of γ irradiation (IIB. As well as, liver function and MDA were increased significantly in the γ - irradiation group (3rd group when compared to control mice (1st group. Gamma irradiation 3rd group revealed increase in the level of T% and B% lymphocytes. According to the obtained results, both γ rays and time period alter

    Haptoglobin (Hp) is an acute-phase protein that is produced by the liver to capture the iron that is present in the blood circulation, thus avoiding its accumulation in the blood. Moreover, Hp has been detected in a wide variety of tissues, in which it performs various functions. In addition, this protein is considered a potential biomarker in many diseases, such as cancer, including ovarian carcinoma; however, its participation in the cancerous processes has not yet been determined. The objective of this work was to demonstrate the expression of Hp and its receptor CCR2 in the ovarian cancer cells and its possible involvement in the process of cell migration through changes in the rearrangement of the actin cytoskeleton using western blot and wound-healing assays and confirming by confocal microscopy. Ovarian cancer cells express both Hp and its receptor CCR2 but only after exposure to ascitic fluid, inducing moderated cell migration. However, when the cells are exposed to exogenous Hp, the expression of CCR2 is induced together with drastic changes in the actin cytoskeleton rearrangement. At the same time, Hp induced cell migration in a much more efficient manner than did ascitic fluid. These effects were blocked when the CCR2 synthetic antagonist RS102895 was used to pretreat the cells. These results suggest that Hp-induced changes in the cell morphology, actin cytoskeleton structure, and migration ability of tumor cells, is possibly "preparing" these cells for the potential induction of the metastatic phenotype.

    In order to explain the biochemical mechanisms associated with deteriorating heart function in broiler chickens, this study compared myocardial high energy phosphate substrates in leghorns, feed restricted (Broilers-Res) broilers, ad libitum fed broilers (Broilers-AL), and in broilers that developed heart failure and ascites. The profile of adenine nucleotide content in the heart tissue did not differ between leghorns and Broilers-Res, but there were significant differences among Broilers-Res, Broilers-AL, and broilers with ascites. During intensive growth periods, leghorns and Broilers-Res showed increasing trends in heart ATP levels, whereas in fast growing broilers the heart ATP declined (pBroilers-Res, declined in fast growing broilers, and were the lowest in broilers that developed heart failure. The changes in heart high energy phosphate profile in broilers suggest that the energy demand of the heart during a rapid growth phase may exceed the bird's metabolic capacity to supply adequate levels of high energy phosphate substrate. The insufficiency of energy substrate likely contributes to the declining heart rate. In some individuals this may lead to impaired heart pump function, and in more severe cases may progress to heart pump failure. PMID:17524693

    Full Text Available Introduction: We evaluated if ascitic fluid sample could be used for the diagnosis of tuberculosis intestinal obstruction (TBIO by a nested polymerase chain reaction (PCR assay and analyzed the clinical and laboratory findings in 33 patients with confirmed intestinal tuberculosis (TB compared to 54 patients with other pathologies of intestinal obstruction. Methods: We tested ascitic fluid sample by Ziehl-Neelson staining; Löwenstein-Jensen (L-J culture method was used for the culture and PCR was performed for targeting the IS6110 sequence. Results: We found that 87.9% (29/33 of cases with intestinal TB and 0% (0/54 with other causes who had positive results with the nested PCR assay. PCR, in principle, is a highly sensitive technique that detects DNA from a single to a few microorganisms with the overall sensitivity, specificity, and positive predictive value (PPV of 87.87%, 100%, and 100%, respectively. Acid-fast bacillus (AFB staining alone has positivity of only 24% and histology alone has positivity of 88%. Conclusion: PCR has a potentially important role in improving the diagnostic accuracy.

  5. Influence of neuraminidase and X-ray irradiation (2 Gy and 8 Gy) on microvilli and membrane invaginations of Ehrlich ascites tumor cells in monolayer culture

    International Nuclear Information System (INIS)

    A monolayer culture (Eagle basal medium plus 10% of fetal calf serum) of Ehrlich ascites tumor cells was exposed to X-radiation with 2 Gy and 8 Gy and treated with Vibrio cholerae neuraminidase alone or combined with sublethal X-ray irradiation (2 Gy). Pictures of the Ehrlich ascites tumor cells taken with the electron microscope were investigated in order to find out any cell surface modifications due to membrane invaginations and microvilli. The results showed that the rate of microvilli as well as that of membrane invaginations became higher with the increasing X-ray dose (2 Gy; 8 Gy). Following to neuraminidase treatment there was a considerable augmentation of membran invaginations as compared to control cells, whereas the number of microvilli was slightly reduced. As it has been already described before, the influence of neuraminidase produced an increased endocytosis activity and a strengthening of the cytoskeleton. Combined treatment with neuraminidase and sublethal X-radiation (2 Gy) caused a higher rate of membrane invaginations than each method alone; the number of microvilli was slightly increased by combined treatment. The conclusion is drawn that these structure modifications are due to reparation processes induced by radiation on the one hand and to an enzymic action of neuraminidase on the cell surface on the other hand.

  6. In vitro effect of X radiation on respiration and glycolysis of Ehrlich ascites carcinoma cells of the mouse - an experimental comparison with the mouse tumortetanus assay

    International Nuclear Information System (INIS)

    Depending on the dose of X-rays, in vitro irradiation of Ehrlich ascites carcinoma cells of the mouse affected both respiration and glycolysis. 38.7 C/kg irradiation suppressed the aerobic and anaerobic energy metabolism rather strongly followed by a reduction of the 'take' and growth of the subcutaneously injected tumour cells, as opposed to the growth behavior of non-irradiated cells. In analogy, tetanus mortality rates were reduced in the mouse tumor-tetanus assay with 38.7 C/kg irradiated cells. On the other hand, irradiation with 5.16 C/kg of Ehrlich carcinoma cells resulted in unchanged rates of respiration and glycolysis, in spite of the strongly limited growth capacity of the tumor cells. The tumor-tetanus assay of the mouse showed good correlation with subcutaneous tumor growth; no such correlation was found in the tetanus assay and the manometric values of respiration and glycolysis with 5.16 C/kg irradiated tumor cells. After subcutaneous injection of mixed cell suspensions consisting of 1 x 105 viable and 1 x 106 38.7 C/kg irradiated Ehrlich ascites carcinoma cells as well as of 3 x 102 tetanus spores per single dose, we observed similar rates of tumor growth and tetanus mortality, respectively, if 1 x 105 viable tumor cells alone were administered together with 3 x 102 tetanus spores, without addition of irradiated tumor cells.

    Accumulation of 2-aminoisobutyrate by mouse ascites tumour cells was studied in circumstances where nigericin reversed the normal direction of the Na+ concentration gradient. The membrane potential (delta psi) was assayed using oxonol V as a voltage-sensitive probe. The amino acid gradient (delta mu A) that formed did not significantly exceed the likely magnitude of the Na+ electrochemical gradient when this was in the range 2-6 kJ mol-1. When delta-Na mu increased up to 11 kJ mol-1, delta mu A was almost constant at 7-8 kJ mol-1. The observations indicate that when delta psi is large changes in cellular [Na+] in the range 16-80 mM scarcely affect delta mu A. PMID:3358997

    Advanced ovarian cancer (AOC) is one of the leading lethal gynecological cancers in developed countries. Based on the important role of angiogenesis in ovarian cancer oncogenesis and expansion, we hypothesized that the development of an “angiogenic signature” might be helpful in prediction of prognosis and efficacy of anti-angiogenic therapies in this disease. Sixty-nine samples of ascitic fluid- 35 from platinum sensitive and 34 from platinum resistant patients managed with cytoreductive surgery and 1st-line carboplatin-based chemotherapy- were analyzed using the Proteome ProfilerTM Human Angiogenesis Array Kit, screening for the presence of 55 soluble angiogenesis-related factors. A protein profile based on the expression of a subset of 25 factors could accurately separate resistant from sensitive patients with a success rate of approximately 90%. The protein profile corresponding to the “sensitive” subset was associated with significantly longer PFS (8 [95% Confidence Interval {CI}: 8–9] vs. 20 months [95% CI: 15–28]; Hazard ratio {HR}: 8.3, p<0.001) and OS (20.5 months [95% CI: 13.5–30] vs. 74 months [95% CI: 36-not reached]; HR: 5.6 [95% CI: 2.8–11.2]; p<0.001). This prognostic performance was superior to that of stage, histology and residual disease after cytoreductive surgery and the levels of vascular endothelial growth factor (VEGF) in ascites. In conclusion, we developed an “angiogenic signature” for patients with AOC, which can be used, after appropriate validation, as a prognostic marker and a tool for selection for anti-angiogenic therapies.

    Yellowtail ascites virus (YAV) is an aquabirnavirus that causes ascites in yellowtail, a fish often used in sushi. Segment A of the YAV genome codes for a polyprotein (pVP2-VP4-VP3), where processing by its own VP4 protease yields the capsid protein precursor pVP2, the ribonucleoprotein-forming VP3, and free VP4. VP4 protease utilizes the rarely observed serine-lysine catalytic dyad mechanism. Here we have confirmed the existence of an internal cleavage site, preceding the VP4/VP3 cleavage site. The resulting C-terminally truncated enzyme (ending at Ala(716)) is active, as shown by a trans full-length VP4 cleavage assay and a fluorometric peptide cleavage assay. We present a crystal structure of a native active site YAV VP4 with the internal cleavage site trapped as trans product complexes and trans acyl-enzyme complexes. The acyl-enzyme complexes confirm directly the role of Ser(633) as the nucleophile. A crystal structure of the lysine general base mutant (K674A) reveals the acyl-enzyme and empty binding site states of VP4, which allows for the observation of structural changes upon substrate or product binding. These snapshots of three different stages in the VP4 protease reaction mechanism will aid in the design of anti-birnavirus compounds, provide insight into previous site-directed mutagenesis results, and contribute to understanding of the serine-lysine dyad protease mechanism. In addition, we have discovered that this protease contains a channel that leads from the enzyme surface (adjacent to the substrate binding groove) to the active site and the deacylating water.

    Objective:To detect the effect of extract of Camellia Sinensis (ECS) and extract of Camellia Ptilophylla Chang (ECPC) on DNA polymerase (Pol) of Ehrlich ascites tumor cells. Methods: Referring to the method of K.Ono, Pol was extracted from Ehrlich ascites tumor cells in mice. Pol α, β, and γ were separated by phosphocellulose column chromatography and were identified. The effect of ECPC and ECS on Pol was studied. Results: ECPC and ECS were shown to inhibit the activity of Pol α, β, and γ. IC50 values of ECS on Polα, β, and γ were 10.2μ g/ml, 9.9μ g/ml and 28.9 μ g/mlrespectively. IC50 values of ECPC on Pol α, Pol β and Pol γ were 5.6 μ g/ml, 15 μ g/ml and 14.7 μ g/mlrespectively. The modes of inhibition of ECPC on Pol α,Pol β and Pol γ were noncompetitive with respect to template DNA. The Ki values of ECPC on Pol α, β, and γ were 2.68± 0.12 μ g/ml, 2.24 ± 0. 12 μ g/ml , 2.56 ±0. 18 μ g/ml . Conclusion: ECPC and ECS were shown to have inhibitory effect on DNA polymerase of tumor cells. The mode of inhibition of ECPC on Pol α, Pol βand Pol γwere noncompetitive with respect to template DNA.

    Local renin-angiotensin systems exist in various malignant tumor tissues; this suggests that the main effector peptide, angiotensin II, could act as a key factor in tumor growth. The underlying mechanisms for the anti-angiogenic effect of angiotensin II type 1 receptor blockers need to be further evaluated. The present study was carried out to investigate the anti-angiogenic effect of olmesartan alone or in combination with sorafenib, an angiotensin (1–7) agonist or an angiotensin (1–7) antagonist in Ehrlich's ascites carcinoma-bearing mice. The tumor was induced by intradermal injection of Ehrlich's ascites carcinoma cells into mice. Tumor discs were used to evaluate the microvessel density; the serum levels of vascular endothelial growth factor (VEGF) and serum insulin-like growth factor I (IGF-I); and their intratumoral receptors, VEGF receptor-2 and IGF-I receptor, respectively. All parameters were determined following the treatment course, which lasted for 21 days post-inoculation. Monotherapy with olmesartan and its combination with sorafenib resulted in a significant reduction in microvessel density and serum levels of VEGF and IGF-I, as well as their intratumoral receptors. In addition, the combination of olmesartan (30 mg/kg) with an angiotensin (1–7) agonist reduced the microvessel density, IGF-I serum levels and the levels of its intratumoral receptor. In conclusion, olmesartan reduced the levels of the angiogenesis markers IGF-I and VEGF and down-regulated the intratumoral expression of their receptors in a dose-dependent manner, and these effects were dependent on the angiotensin (1–7) receptor. These results suggest that olmesartan is a promising adjuvant to sorafenib in the treatment of cancer. PMID:24465768

    This two-arm, randomised, multicentre, open-label, phase IIIb study investigated the safety and efficacy of a 3-h catumaxomab infusion with/without prednisolone premedication to reduce catumaxomab-related adverse events. Patients with malignant ascites due to epithelial cancer received four 3-h intraperitoneal catumaxomab infusions with/without intravenous prednisolone (25 mg) premedication before each infusion. The primary safety endpoint was a composite safety score calculated from the incidence and intensity of the most frequent catumaxomab-related adverse events (pyrexia, nausea, vomiting and abdominal pain). Puncture-free survival (PuFS) was a co-primary endpoint. Time to next puncture (TTPu) and overall survival (OS) were secondary endpoints. Prednisolone premedication did not result in a significant reduction in the main catumaxomab-related adverse events. The mean composite safety score was comparable in both arms (catumaxomab plus prednisolone, 4.1; catumaxomab, 3.8; p = 0.383). Median PuFS (30 vs. 37 days) and TTPu (78 vs. 102 days) were shorter in the catumaxomab plus prednisolone arm than in the catumaxomab arm, but the differences were not statistically significant (p = 0.402 and 0.599, respectively). Median OS was longer in the catumaxomab plus prednisolone arm than in the catumaxomab arm (124 vs. 86 days), but the difference was not statistically significant (p = 0.186). The superiority of catumaxomab plus prednisolone versus catumaxomab alone could not be proven for the primary endpoint. Prednisolone did not result in a significant reduction in the main catumaxomab-related adverse events. The study confirms the safety and efficacy of catumaxomab administered as four 3-h intraperitoneal infusions for the treatment of malignant ascites. PMID:24965536

  20. Role of isothiocyanate conjugate of pterostilbene on the inhibition of MCF-7 cell proliferation and tumor growth in Ehrlich ascitic cell induced tumor bearing mice

    International Nuclear Information System (INIS)

    Naturally occurring pterostilbene (PTER) and isothiocyanate (ITC) attract great attention due to their wide range of biological properties, including anti-cancer, anti-leukemic, anti-bacterial and anti-inflammatory activities. A novel class of hybrid compound synthesized by introducing an ITC moiety on PTER backbone was evaluated for its anti-cancer efficacy in hormone-dependent breast cancer cell line (MCF-7) in vitro and Ehrlich ascitic tumor bearing mice model in vivo. The novel hybrid molecule showed significant in vitro anti-cancer activity (IC50=25±0.38) when compared to reference compound PTER (IC50=65±0.42). The conjugate molecule induced both S and G2/M phase cell cycle arrest as indicated by flow cytometry analysis. In addition, the conjugate induced cell death was characterized by changes in cell morphology, DNA fragmentation, activation of caspase-9, release of cytochrome-c into cytosol and increased Bax: Bcl-2 ratio. The conjugate also suppressed the phosphorylation of Akt and ERK. The conjugate induced cell death was significantly increased in presence of A6730 (a potent Akt1/2 kinase inhibitor) and PD98059 (a specific ERK inhibitor). Moreover, the conjugated PTER inhibited tumor growth in Ehrlich ascitic cell induced tumor bearing mice as observed by reduction in tumor volume compared to untreated animals. Collectively, the pro-apoptotic effect of conjugate is mediated through the activation of caspases, and is correlated with the blockade of the Akt and ERK signaling pathways in MCF-7 cells. - Highlights: • Conjugate was prepared by appending isothiocyanate moiety on pterostilbene backbone. • Conjugate showed anticancer effects at comparatively lower dose than pterostilbene. • Conjugate caused blockage of the Akt and ERK signaling pathways in MCF-7 cells. • Conjugate significantly reduced solid tumor volume as compared to pterostilbene

    ía comprende diversas alteraciones fisiopatológicas que han provocado la implementación de diversas modalidades de manejo tanto farmacológico como invasivas para el tratamiento eficaz de la misma.Ascites, defined as the presence of fluid in the peritoneal cavity, is a finding associated to several pathologies, mainly hepatic and cancer diseases. Between 15 and 50 per cent of patients with cancer develop ascites. Its incidence is high in ovary, breast, endometrium, colon, stomach, pancreas and bronchus cancer. Several factors are involved in its pathogenesis, included high hydrostatic pressure, low colloid-osmotic pressure, increased capillary permeability and fluid leakage to the peritoneal cavity. The ascitic fluid is analyzed for diagnostic (serum-ascitic albumin gradient, amylase and triglyceride levels; cell count, culture and Gram staining; pH, cytology, glucose and fibronectine determination and therapeutic purposes. A physical examination is essential for the diagnosis, with particular attention to classical signs such as convex flanks, wave sign, pleural effusion sign, limb, pelvic and genital edema, etc. Other specific studies are sometimes required in order to verify the presence of fluid in the abdominal cavity. Its treatment will depend on the etiology. In non-cancer patients, diet salt restriction and diuretics regimes obtain satisfactory results. In cancer patients, intra-peritoneal chemotherapy may be required. Patients with poor or null response are candidates for drainage of the ascitic fluid. This can be done using several techniques such as classical paracentesis, total paracentesis, placement of a semi-permanent or permanent drainage with or without image help, shunts, etc. In order to obtain the maximum benefit with the minimum risk, patient global status must be assessed prior to the procedure. It is concluded that ascites of any etiology encompass diverse physiopathological disorders that require both pharmacological and invasive therapies for their

    Between February 1993 and March 1994 a prospective descriptive study was carried out in 25 cirrhotic patients (three of them on two occasions with clinical or ultrasonographic ascites; they were hospitalized in the Internal Medicine ward of San Vicente de Paúl Hospital, in Medellín, Colombia, because of decompensation. All of them went through diagnostic paracentesis with cytologic, bacteriologic and chemical studies. Average age was 43.9 years (13 to 77 years, 13 were women (52% and 12 men (48%. Infection of the ascitic fluid was found in 11 cases (39.3%, namely: Bacterascites 6 cases (monomicrobial 3 cases (27.3%, polymicrobial 3 cases (27.3%», spontaneous bacterial peritonitis 3 cases (polymicrobial 2 cases (18.2% and monomicrobial1 case (9.1 %» and neutrocytic ascites 2 cases (18.2%. Seventy two percent of the infectious episodes caused fever (p < 0.01 and in 46% there was abdominal pain (p < 0.1. AII patients with infected ascites belonged to Child's classification C. Serum albumin levellower than 2 g/dl was a risk factor for developing infection. Escherichia coli was cultivated on 5 occasions (45.5%, viridans group of Streptococci in 5 (45.5%, anaerobes in 3 (27.3% and other bacteria in 3 (27.3%. Mortality due to infected ascites was 27.3% (3 cases, comparable to that produced by other causes that was 29.4% (5/17. We conclude that ascitic fluid infection is a common complication in decompensated cirrhotic patients. Thecardinal clinical signs are fever and abdominal pain. The frequent isolation of E. coli and viridans group Streptococci has to be taken into account for the initiation of antibiotic therapy in cases with clinical suspicion.

    Enzyme fractions were isolated from Ehrlich ascites cells which introduced methyl groups into methyl deficient rat liver mRNA and unmethylated vaccinia mRNA. The methyl groups were incorporated at the 5' end into cap 1 structures by the viral enzyme, whereas both cap 0 and cap 1 structures were formed by the Ehrlich ascites cell enzymes. Preliminary results indicate the presence of adenine N/sup 6/-methyltransferase activity in Ehrlich ascites cells. These results indicate that mRNA deficient in 5'-cap methylation and in internal methylation of adenine accumulated in rats on exposure to ethionine. The methyl-deficient mRNA isolated from the liver of ethionine-fed rats differed in its translational properties from mRNA isolated from control animals. Preliminary experiments indicate that single topical application of 17n moles of TPA to mouse skin altered tRNA methyltransferases. The extent of methylation was increased over 2-fold in mouse skin treated with TPA for 48 hours. These changes have been observed as early as 12 hours following TPA treatment. In contrast, the application of initiating dose of DMBA had no effect on these enzymes. It should be emphasized that the changes in tRNA methyltransferases produced by TPA are not merely an increase of the concentration of the enzyme, rather that they represent alterations of specificity of a battery of enzymes. In turn the change in enzyme specificity can produce alterations in the structure of tRNA. (ERB)

    Full Text Available This experiment was conducted to evaluate the effect of some feed restriction regimes on the performance, carcass characteristics and hematological values of broiler chickens. A number of 480 one-day-old Cobb broilers were distributed into 24 floor pens and reared for 42 days. A basal diet was formulated according to the NRC (1994 recommendations for starter (1-11 d, grower (12-28 d and finisher (29-42 d periods. The restricted birds were fed 8 h per day from 7 to 21 (R7-21d, 14 to 28 d (R14-28d or from 21 to 35d (R21-35d, while the control birds were fed ad libitum. Birds and feed were weekly weighed, and dead birds were submitted to necropsy to determine the cause of death. At the end of experiment, blood samples were taken from 3 birds per pen, birds were weighed, and organ weights were recorded. All birds in the feed restriction treatments had lower body weight gain and feed intake than those fed ad libitum. Feed conversion ratio (FCR was better in birds under R7-21d as compared to the control group (p<0.05. R7-21d and R14-28d birds presented lower general mortality and death due to ascites as compared to ad libitum-fed broilers. The birds under R21-35d and R14-28d treatments had lower breast weight and abdominal fat weight as compared to control birds, respectively (p<0.05. A similar trend was observed for the percentage of the mentioned cuts. The right/total ventricular weight ratio (RV/TV was significantly lower both in R7-21d and R14-28d treatments as compared to the control group. Blood constituents, such as glucose, cholesterol, and lactate dehydrogenase were also significantly altered by feeding regimes (p<0.05. The results of present study showed that R7-21d reduced ascites incidence, but had no significant effect on growth performance.

    Full Text Available In order to investigate the presence of adaptive response in cancerous cells, two monofunctional alkylating agents, namely, ethyl methanesulfonate (EMS and methyl methanesulfonate (MMS, were employed to treat Ehrlich ascites carcinoma (EAC cells in vivo. Conditioning dose of 80 mg/kg body weight of EMS or 50 mg/kg body weight of MMS and challenging dose of 240 mg/kg body weight of EMS or 150 mg/kg body weight of MMS were selected by pilot toxicity studies. Conditioned EAC cells when challenged after 8 h time lag resulted in significant reduction in chromosomal aberrations compared to challenging dose of respective agents. As has been proved in earlier studies with normal organisms, even in cancerous cells (EAC, there is presence of adaptive response to methylating and ethylating agents. Furthermore, it is also interesting to note in the present studies that the methylating agent, MMS, is a stronger inducer of the adaptive response than the ethylating agent, EMS.

    Full Text Available A primipara presented to our hospital due to fetal ascites, bilateral hydronephrosis and hydrometrocolpos. The female baby had two giant abdominal cysts, a single atrium and foot polydactyly. Absence of the vaginal orifice was noticed, and the hymen was broken through; the left cyst collapsed after fluid drainage. The right cyst was punctured and drained, which improved the hydronephrosis. Contrast imaging showed medium pouring into the abdominal cavity via the uterine tube; the right cyst was a 6 × 5 cm closed cavity. Vaginal uroplania persisted even after hospital discharge. At the age of 4 years, cystoscopy showed a fistulous opening on the urethra 5 mm distal from the internal urethral orifice. A catheter inserted via the opening was found in the vagina. In our case, urine poured into the abdominal cavity through the fistula and uterine tube; following obstruction of the uterine tube, giant hydrometrocolpos and hydrosalpinx appeared. Three cases of congenital urethrovaginal fistula (CUVF with imperforate hymen have been reported. A remnant of communication between the uterovaginal primordium and urogenital sinus may be responsible for CUVF.

  13. Activity and characterization of sialyltransferase from serum of normal rats, of bearing Zajdela ascitic hepatoma, in normal host liver and in Zajdela hepatoma cells

    International Nuclear Information System (INIS)

    Comparative studies on the content of sialic acid and on the sialyltransferase activity in normal serum and in serum of rats with Zajdela ascitic in different phases of tumor development have been conducted. Unlike the serum from animals with tumors, in which the sialic acid quantity increases in dependence of the stage of tumor development, the activity of serum sialyltransferase statistically augmented only in serum of rats at the final stage of tumor progression. The sialyltransferase activity towards asialofetuin as an acceptor in normal liver and in Zajdela hepatoma cells, was measured and a decrease in this activity in tumor cells as well as in host liver was found. When lactose was used as acceptor, again lower activity in the tumor cells in comparison with that in liver was established, but in liver and in hepatoma cells the predominant 14C-labelled product of the sialyltransferase assay was alpha(2-6)sialyllactose isomer. The results contribute to the biochemical characterization of rat Zajdela hepatoma. (author)

  14. Turnover of [14C]thiamin and activities of thiamin pyrophosphate-dependent enzymes in tissues of mice with Ehrlich ascites carcinoma

    International Nuclear Information System (INIS)

    Turnover of [14C]thiamin was studied in mice with Ehrlich ascites carcinoma fed a thiamin-deficient diet and injected with 5 or 2 micrograms/mouse of the labeled vitamin. The process of conversion of [14C]thiamin to thiamin pyrophosphate (TPP) was monitored by measuring the activities of transketolase, pyruvate dehydrogenase, and oxoglutarate dehydrogenase. The amount of coenzyme-unsaturated apotransketolase was assessed by measuring the TPP effect--determining transketolase activity with and without the addition of TPP in vitro. Tumor growth was accompanied by thiamin deficiency, manifested in an increase in [14C]thiamin incorporation into the host tissues and the absence of saturation of the tissues with the labeled vitamin over 13 days. Increased values for the turnover coefficients, reduction of thiamin-dependent enzyme activities, elevation of the TPP effect, and a decrease in urinary excretion of the radioactive products also provided evidence for a disturbance in thiamin metabolism. The severity of the disturbance in thiamin metabolism during malignant tumor growth was directly related to the dose of the exogenous vitamin

  15. Effect of 2-deoxy-D-glucose on DNA double strand break repair, cell survival and energy metabolism in euoxic Ehrlich ascites tumour cells

    International Nuclear Information System (INIS)

    Effects of 2-deoxy-D-glucose (2-DG) on DNA double strand break (dsb) repair, cell survival and on the energy metabolism were investigated in exponentially growing Ehrlich ascites tumour (EAT) cells. Cells in suspension were exposed to 40 Gy of X-rays and allowed to repair (up to 4h) with or without 2-DG at 37oC. DNA dsb rejoining was measured by means of clamped homogeneous electric field (CHEF), a pulsed field gel electrophoresis technique. The fraction of activity released (FAR) during electrophoresis (DNA associated 14C-thymidine) was used as a parameter to determine the number of dsb present in the DNA. Biphasic kinetics for dsb repair were observed. The presence of 2-DG significantly inhibited the slow component of dsb repair. The presence of 2-DG also enhanced radiation-induced cell killing. ATP content of cells was measured by a bioluminescence method. ATP content in exponentially growing cells was about 4 pg per cell. The level of ATP was reduced by 50% in presence of 2-DG (C2-DG/CG = 1.0). (author)

    Intravenous injection of microparticles (MPs) is a tool to reveal susceptibility to pulmonary hypertension (PH) syndrome (PHS, ascites) in broilers. After injection MPs get lodged in pulmonary arterioles and cause localized inflammation. To examine the expression of chemokines/cytokines during the MP-induced pulmonary inflammatory response, lungs were collected from 4-week-old broilers (6/line/time point) from the PHS-resistant (RES) and -susceptible (SUS) broilers before (0h) and after (2, 6, 12, 24, and 48h) MP injection and analyzed using quantitative RT-PCR. In both lines, expression of interleukin-1beta (IL-1beta), IL-6, IL-8, and K60 increased from 0 to 6h, reached peak levels at 6 and 12h, and decreased thereafter, whereas IL-4 and interferon gamma (IFN-gamma) expression remained elevated past 12h. Lungs from the RES line broilers had higher expression (Pbroilers. Higher expression of chemokines/cytokines in RES compared to SUS line lungs may explain the ability of RES line broilers to effectively counteract the MP-induced PH and resolve the vascular occlusion.

    Full Text Available To investigate the involvement of actin filaments in concanavalin A (Con A-induced cap formation and cytochalasin B (CB-induced zeiotic knob migration, the distribution of F-actin was studied in Con A-treated and CB-treated Ehrlich ascites tumor cells (EATC by fluorescence microscopy using heavy meromyosin conjugated with a fluorescent dye, N-(7-dimethylamino-4-methylcoumarinyl maleimide, (DACM-HMM. In non-treated cells, the diffuse fluorescence of DACM-HMM was observed in the cytoplasm, particularly intensely under the plasma membrane and around the nucleus. In Con A- and CB-treated cells, the fluorescence was seen at Con A-induced-capped and CB-induced-knob-accumulated regions. This fluorescence was more intense in CB-treated cells. To study the actin filaments in these fluorescent regions more clearly, the soluble components of the cells were eliminated by treatment with Triton X-100 or saponin solution containing a low concentration of glutaraldehyde, and the detergent-treated and saponin-treated cells were observed under a transmission electron microscope. Concentrated actin filaments were observed directly beneath the Con A-induced capping area and CB-induced zeiotic knob-accumulation area. The area of concentrated actin filaments appeared to correspond to the electron dense area observed in the identical region in the cells fixed without detergent treatment. More actin filaments were observed in CB-treated cells than in Con A-treated ones.

    Purification of immunoglobulin M (IgM) antibodies could be challenging, and is often characterized by the optimization of the purification protocol to best suit the particular features of the molecule. Here, two different schemes were compared to purify, from ascites, the 1E4 IgM monoclonal antibody (mAb) previously raised against the stage of redia of the trematode Fasciola hepatica. This immunoglobulin is used as capture antibody in an immunoenzymatic assay to detect parasite ongoing infection in its intermediate hosts. The first purification protocol of the 1E4 mAb involved two chromatographic steps: an affinity chromatography on a Concanavalin A matrix followed by size exclusion chromatography. An immunoaffinity chromatography was selected as the second protocol for one-step purification of the antibody using the crude extract of adult parasites coupled to a commercial matrix. Immunoreactivity of the fractions during purification schemes was assessed by indirect immunoenzymatic assays against the crude extract of F. hepatica rediae, while purity was estimated by protein electrophoresis. Losses on the recovery of the antibody isolated by the first purification protocol occurred due to protein precipitation during the concentration of the sample and to low resolution of the size exclusion molecular chromatography step regarding this particular immunoglobulin. The immunoaffinity chromatography using F. hepatica antigens as ligands proved to be the most suitable protocol yielding a pure and immunoreactive antibody. The purification protocols used are discussed regarding efficiency and difficulties. PMID:26828226

    Full Text Available Analysis of ascitic fluid should help to identify and characterize malignant cells in gastrointestinal cancer. However, despite a high specificity, the sensitivity of traditional ascitic fluid cytology remains insufficient, at around 60%. Since 2004 the CellSearch® technology has shown its advantages in the detection of circulating tumor cells (CTCs in peripheral blood, which can perform an accurate diagnosis and molecular analysis at the same time. To our knowledge, no previous study has explored the potential utility of this technology for the detection and quantification of tumor cells in ascitic fluid samples. Herein we report a case of metastatic esophageal adenocarcinoma in a 70-year-old man presenting with dysphagia and a large amount of fluid in the peritoneal cavity. Analysis of a peripheral blood sample and ascites sample with the CellSearch® technology both revealed the presence of putative tumor cells that were positive for epithelial cell adhesion molecule (EpCAM and cytokeratin (CK expression. This study confirmed the hematogenous dissemination of esophageal cancer by the detection of circulating tumor cells in the peripheral blood, and is the first to demonstrate that tumor cells can be identified in ascitic fluid by using CellSearch® technology.

    The clinical success of the applicability of tea polyphenols awaits efficient systemic delivery and bioavailability. Herein, following the concept of nanochemoprevention, which uses nanotechnology for enhancing the efficacy of chemotherapeutic drugs, we employed tea polyphenols, namely theaflavin (TF) and epigallocatechin-3-gallate (EGCG) encapsulated in a biodegradable nanoparticulate formulation based on poly(lactide-co-glycolide) (PLGA) with approximately 26% and 18% encapsulation efficiency, respectively. It was observed that TF/EGCG encapsulated PLGA nanoparticles (NPs) offered an up to ~7-fold dose advantage when compared with bulk TF/EGCG in terms of exerting its antiproliferative effects and also enhanced the anticancer potential of cisplatin (CDDP) in A549 (lung carcinoma), HeLa (cervical carcinoma), and THP-1 (acute monocytic leukemia) cells. Cell cycle analysis revealed that TF/EGCG-NPs were more efficient than bulk TF/EGCG in sensitizing A549 cells to CDDP-induced apoptosis, with a dose advantage of up to 20-fold. Further, TF/EGCG-NPs, alone or in combination with CDDP, were more effective in inhibiting NF-κB activation and in suppressing the expression of cyclin D1, matrix metalloproteinase-9, and vascular endothelial growth factor, involved in cell proliferation, metastasis, and angiogenesis, respectively. EGCG and TF-NPs were also found to be more effective than bulk TF/EGCG in inducing the cleavage of caspase-3 and caspase-9 and Bax/Bcl2 ratio in favor of apoptosis. Further, in vivo evaluation of these NPs in combination with CDDP showed an increase in life span (P<0.05) in mice bearing Ehrlich’s ascites carcinoma cells, with apparent regression of tumor volume in comparison with mice treated with bulk doses with CDDP. These results indicate that EGCG and TF-NPs have superior cancer chemosensitization activity when compared with bulk TF/EGCG. PMID:26586942

  2. Gastrodin stimulates anticancer immune response and represses transplanted H22 hepatic ascitic tumor cell growth: Involvement of NF-κB signaling activation in CD4 + T cells

    International Nuclear Information System (INIS)

    Gastrodia elata Blume (G. elata) is a famous restorative food in East Asia. It can be used as an auxiliary reagent in hepatocellular carcinoma (HCC) treatment. Previous studies unveiled that G. elata exhibited immunomodulatory activities. To explore the active ingredients contributing to its immunomodulatory activities, gastrodin, vanillin, and parishin B were purified from G. elata and their anti-HCC effects were assessed in vivo. Among these compounds, only gastrodin was capable of repressing transplanted H22 ascitic hepatic tumor cell growth in vivo with low toxicity. Further investigations were designed to explore the effects of gastrodin on the immune system of tumor-bearing mice and potential molecular mechanisms underlying these effects. Our data showed that gastrodin ameliorated tumor cell transplantation-induced activation of endogenous pro-apoptotic pathway in CD4 + T cells and abnormalities in serum cytokine profiles in host animals. These events enhanced cytotoxic activities of natural killer and CD8 + T cells against H22 hepatic cancer cells. Gastrodin administration specifically upregulated mRNA levels of several nuclear factor κB (NF-κB) responsive genes in CD4 + T cells but not in CD8 + T cells. Chromatin immunoprecipitation assay showed that gastrodin increased the association of NF-κB p65 subunit to the promoter regions of IL-2 and Bcl-2 encoding genes in CD4 + T cells. Our investigations demonstrated that gastrodin is the main active ingredient contributing to the anticancer immunomodulatory properties of G. elata. Promoting NF-κB-mediated gene transcription in CD4 + T cells is implicated in its immunomodulatory activity. - Highlights: • Gastrodin stimulates anticancer immune response. • Gastrodin represses tumor transplantation-induced CD4 + T cell apoptosis. • Gastrodin activates NF-κB activity in CD4 + T cells

    The present study is an attempt to investigate the possibility that ultraviolet irradiation in the presence of pheomelanin may be more harmful to cells than the irradiation in the presence of eumelanin. The effects of UV-visible irradiation upon Ehrlich ascites carcinoma cells in the presence of the melanin isolated from human black hair (eumelanin) or from red hair (pheomelanin) were investigated. Irradiation of these cells was found to produce cell lysis, as observed by leakage of 51Cr from labeled cells and intracellular lactic dehydrogenase from the cells and decrease in cell viability demonstrated by the trypan blue exclusion test. The three parameters were quantitatively parallel to one another under various experimental conditions, namely different periods of irradiation and irradiation in the presence of different concentrations of melanin. The above effects were more pronounced when the irradiation was carried out in the presence of melanin from red hair than in the presence of black-hair melanin. In the absence of either melanin, the irradiation did not produce any significant effect in cell viability or cell lysis. Irradiation of the cells in the presence of red-hair melanin also decreased the transplantability of these cells. These observations clearly show that irradiation of cells in the presence of pheomelanin could produce cytotoxic effects. The present experimental design may have application in the development of in vitro models for the study of UV radiation-induced cutaneous carcinogenesis. The reactions of pheomelanin may be related to the susceptibility of ''Celtic'' skin to UV radiation-induced skin damage and carcinogenesis.

  4. Effect of grape seed extract on hepatic function and antioxidant status of Mouse bearing Ehrlich Ascites carcinoma and exposed to gamma radiation

    International Nuclear Information System (INIS)

    Grape seed extract (GSE), rich in bioactive phytochemicals commonly known as procyanidins, is one of the most commonly consumed dietary supplements in USA and Europe due to its several health benefits. The present study was performed to investigate the anti- tumor effect of GSE on Ehrlich ascites carcinoma cells (EAC)-induced oxidative stress, hepatic dysfunction and histopathological changes in the liver of albino mouse. GSE was orally administered to mice for 5 consecutive days at the dose of 100 mg/kg body weight before and after tumor inoculation. On the 5th day of tumor inoculation, animals were exposed to 1 Gy whole body gamma radiation. The anti-tumor effect of GSE was evident in terms of a significant reduction in tumor viable cells count and increased non-viable cells count of EAC-tumor bearing mice. Biochemical investigations showed that EAC cells led to hepatic disturbances in liver function profile. Oral administration of GSE, with or without subsequent gamma irradiation, improved liver functions through a significant recovery of the elevated levels of serum alanine aminotransferase (ALT), lactate dehydrogenase (LDH), gamma glutamyl transpeptidase (gamma-GT) and alkaline phosphatase (AP) in the EAC-bearing mice groups. The results of the present study revealed that, pretreatment of mice with GSE induced a significant reduction of lipid peroxidation and significant improvement in glutathione, superoxide dismutase, catalase as well as glutathione peroxidase activities in liver compared with those EAC damaged mice. Histopathological studies showed that EAC cells caused fatty degeneration, enlargement of liver cells nuclei and presence of necrosis. Pretreatment of animals with GSE exhibited protection justified by the results of the biochemical studies. It could be concluded that GSE administrated to mice, with or without subsequent gamma irradiation, exhibited anti-tumor effect reflected by improving liver function profile, modulating lipid peroxidation

  5. Radiotherapeutic response of Ehrlich Ascites tumor cells perfused in agarose gel threads and implanted in mice. A 31P MR spectroscopy study

    International Nuclear Information System (INIS)

    Aim: In order to obtain better understanding of radiation-induced alterations in intracellular metabolism, a dynamic and noninvasive experimental model system is required. A serial study in cultured tumor cell line followed by verification in the in vivo samples may be of considerable value for non-invasive prediction and/or detection of tumor response to therapy. The present study was undertaken to evaluate the radiation response of perfused Ehrlich ascites tumors cells (EATC) immobilized in agarose gel matrix to that observed in mouse bearing EATC tumor, in order to identify biomarkers of radiation response. Materials and Methods: Perfused EAT cells, entrapped in agarose gel threads were irradiated in the perfusion assembly outside the magnet with fast electrons (6 Gy, 1 Gy/min) using 30 MeV Betatron. Solid EATC tumors implanted subcutaneously onto right hand limb of Swiss-albino strain 'A' mice, were focally irradiated using 60Co teletherapy (10 Gy, 0.4 Gy/min). Metabolites changes were monitored by 31P MR spectroscopic techniques. Results: A post-irradiation decrease in the levels of ATP and ADP along with an increase in inorganic phosphate and glycerophosphocholine levels was observed. The ratios of β-phosphate of ATP to inorganic phosphate (β-ATP-Pi), and phosphocholine to glycerophosphocholine (PC/GPC), declined during 1-5 hours following irradiation, in perfused EAT cells and in the solid tumors implanted in mice. Conclusion: Perfused cells could be used as a simple model of tumor for prediction of clinical radiotherapeutic response. The present study demonstrates that radiation damage may be occurring both at the DNA protein as well as the membrane lipid levels. Therefore, the bioenergetics and phospholipid profiles of tumor cells could be used as complimentary, reliable and sensitive indirect indicators for devising predictive assays for assessment and monitoring of radiation response, which will also facilitate the individualization and optimization of

    Two experiments were conducted to evaluate the effects of arginine (Arg) and vitamin E (VE) on ascites (pulmonary hypertension syndrome) parameters, nitric oxide synthase (NOS) activity, and cardiopulmonary performance after an acute challenge with epinephrine (Epi). One-day-old male broilers (n = 100) were fed a commercial corn-soybean meal-based diet meeting NRC (1994) requirements, including 1.2% Arg and 40 IU of VE/kg. In experiment 1, birds were provided tap water (control), water with 0.3% Arg (HArg), water with 400 IU of VE/L (HVE), or a combination of both compounds (Arg-VE). In experiment 2, the treatment groups were similar but the VE was incorporated in the diet (400 IU/ kg of feed). At d 18, temperature was reduced to amplify the incidence of pulmonary hypertension. Body weight and hematocrit were recorded weekly. From d 28 to 42, cardiopulmonary performance was evaluated in clinically healthy, anesthetized birds (n = 7 to 8/treatment). A pulmonary artery and a systemic artery were cannulated, the birds were allowed to stabilize for 10 min (basal), an i.v. injection of Epi was applied (1 or 0.5 mg/kg of BW, experiment 1 and 2, respectively), and a second dose was applied 20 min later. Pulmonary arterial pressure (PAP), mean arterial pressure (MAP), and heart rate (HR) were recorded continuously and data were analyzed by repeated measures ANOVA. The NOS activity was estimated through the conversion of 14C-Arginine to 14C-citrulline in isolated pulmonary arteries. Right/total ventricular weight ratio (RV/TV) was recorded at the end of the experiment. Body weight, RV/TV, and hematocrit values were not significantly affected by the dietary treatments. The PAP increased (P < 0.01) within 30 s after Epi in all treatments, except the HArg treatment in experiment 2. Overall, the time taken for PAP to return to basal levels was longer in the Arg-VE birds and shorter in the HArg birds, particularly after the second challenge. However, although NOS activity was

    The continuous selection for rapid growth has been accompanied by an increasing occurrence of ascites syndrome (AS), which develops in broilers failing to supply the increasing demand for O(2) in their bodies. Moderate heritability has been reported for AS in broiler populations, suggesting that selection against AS is feasible. However, direct selection based on AS mortality requires exposure of candidate birds to AS-inducing conditions (AIC), which hinder selection for performance traits. Noninvasive indicators of AS, expressed under standard husbandry, may facilitate the integration of selection against AS into breeding programs. This study was designed to look for differences in heart rate, hematocrit, O(2) saturation of hemoglobin in arterial blood (SaO(2)), BW, and weight gain, all measured at early ages under standard brooding conditions, between birds that later developed AS and those that remained healthy under AIC, and to estimate the heritability of these AS-related parameters and their genetic correlation with the tendency of broilers to develop AS. The experimental population was derived from a broiler dam line. Male progeny of 34 half-sib sire families were reared under standard brooding conditions to 19 d of age, then under an AIC protocol consisting of housing in individual cages, cool air high-speed ventilation, and growth enhancement using high-energy pelleted feed and 23 h/d of light. Birds were necropsied upon mortality or at the end of the trials and were recorded as being susceptible, with manifestations of AS (SUS), or resistant and healthy (RES). About 44% developed AS, confirming the efficacy of the novel AIC protocol. The SUS and RES chicks did not differ in BW and weight gain up to 19 d of age, suggesting that there was no association between AS susceptibility and rapid early growth. The SUS chicks exhibited lower SaO(2) and heart rate than the RES chicks. Moderate heritability was estimated for all traits, but only SaO(2) exhibited

    Full Text Available Abstract Introduction Surgical treatment is the usual therapy for patients with polycystic liver disease and with severe symptoms, yet the results of surgery are often disappointing and the optimal surgical approach is uncertain. Case presentation We present the case of a 41-year-old Greek woman who underwent combined left hepatectomy with fenestration for symptomatic polycystic liver disease using ultrasound scalpel, fibrin glue and closed suction drain to prevent bile leakage, haemorrhage and ascites. Liver resection using the ultrasound scissors allowed quick parenchyma dissection under haemostatic conditions with safe coagulation of small vessels and bile ducts. Moreover, the ultrasound scalpel was applied to the cyst cavities exposed on the peritoneum to ablate the fluid-producing epithelial cyst lining. We also covered the cut cystic cavities exposed to the peritoneum surface of the liver with fibrin glue. Instead of allowing the opened cysts to drain into the abdominal cavity, we used two wide bore closed suction fluted drains. We did not observe excessive fluid loss through the drainage after the second postoperative day. The drain tubes were removed on the third postoperative day. Conclusion In our patient, effective treatment of ascites and prevention of bile leakage and bleeding indicate that this new approach is promising and may become a useful surgical technique for polycystic liver disease.

    The objective of this work is to report the antiproliferative effect of P. cupana treatment in Ehrlich Ascites Carcinoma (EAC)-bearing animals. Female mice were treated with three doses of powdered P. cupana (100, 1000 and 2000 mg/kg) for 7 days, injected with 10(5) EAC cells and treated up to day 21. In addition, a survival experiment was carried out with the same protocol. P. cupana decreased the ascites volume (p = 0.0120), cell number (p = 0.0004) and hemorrhage (p = 0.0054). This occurred through a G1-phase arrest (p < 0.01) induced by a decreased gene expression of Cyclin D1 in EAC cells. Furthermore, P. cupana significantly increased the survival of EAC-bearing animals (p = 0.0012). In conclusion, the P. cupana growth control effect in this model was correlated with a decreased expression of cyclin D1 and a G1 phase arrest. These results reinforce the cancer therapeutic potential of this Brazilian plant. PMID:20564499

    In recent ten years one of the major problems of modern radiobiology is the study of radiation protective mechanisms with the help of different substances as well as activation of internal resources of the organism. Internal resources mean such phenomena as hormesis and adaptive response which represent cell or body reaction on low doses of inducing factors and predetermine their further high dose effect resistance. At present special interest is attracted by studies of biological effects of low-dose-rate high-LET radiation because of searching for new types of radiation for more effective cancer therapy and searching for new methods of radiation protection. Since natural biologically active substances have low toxicity and are capable of affecting physiological processes taking place in human’s organism and increasing organism’s natural defense system, the interest to protective means of vegetal origin and search of special food supplements intensifies every year. The purpose of this study is to investigate the combined influence of food supplement, low dose rate high-LET radiation simulating high-altitude flight conditions and X-ray radiations on radiosensitivity, induction of radiation adaptive response (RAR) and growth of Ehrlich ascite carcinoma as well. Experiments were performed with males of SHK mice at the age of two months. The animals were being irradiated with low-dose-rate high-LET radiation with the dose of 11,6 cGy (0,5 cGy/day) behind the concrete shield of the 70 GeV protons accelerator (Protvino). The X-ray irradiation was carried out on the RTH device with a voltage of 200 kV (1 Gy/min; Pushchino). The diet composition included products containing big amount of biologically active substances, such as: soybeam meat, buckwheat, lettuce leaves and drug of cod-liver oil. Four groups of mice were fed with selected products mentioned above during the whole irradiation period of 22 days. The control groups received the same food without irradiation

    Malignant tumor may be detected using various diagnostic methods. Different techniques can reveal various results for the same lesion; thus, clinicians must seriously consider the approach selected. This study introduces a case that was the subject of a multidisciplinary comprehensive discussion at the Tianjin Medical University Cancer Institute and Hospital. A patient presented with malignant ascites. Positron emission tomography-computed tomography examination revealed more thyroid, parotid gland, and umbilical lesions, which were all considered malignant. B-mode ultrasound was used to assess the thyroid and parotid benign lesions, as well as the umbilical lesions for metastatic tumor. The primary lesions were not definite although the umbilical lesions were metastatic ade-nocarcinoma, as determined by aspiration biopsy. The multidisciplinary consultation committee determined that the patient had peritoneal carcinoma through analysis of radiologic, pathologic, and immunohistochemical characteristics. This case presentation suggests that the pathological approach remains the gold standard for malignant tumor diagnosis. Reasonable selection of an immunohistochemical item to determine the source of the carcinoma is considerably significant.%目前恶性肿瘤的诊断方法日益丰富,临床医师在选择检查手段时也面临多种选择,而对于同一个肿瘤不同的检查方法或许会出现截然不同的结果,对此临床医师需要全面思考和判断.现介绍1例天津医科大学附属肿瘤医院多学科综合讨论病例供大家参考.本例患者主因“恶性腹水”就诊,PET-CT检查发现甲状腺、腮腺和脐部等多处病变,考虑恶性,而B超检查考虑甲状腺和腮腺病变为良性,脐部病变为转移瘤.针吸活检诊断脐部病变为转移性腺癌,但所有检查未能确诊原发病灶.最终,经过分析其影像学表现、病理特征和免疫组化指标,多学科咨询委员会认为本例患

    Over the past decade, yeast display technology has emerged as a powerful tool for the isolation of high-affinity immunoglobulin fragments with potential utility as clinical diagnostic and therapeutic reagents. Despite significant refinement of the various methodologies underpinning library construction and selections, certain aspects remain challenging and process limiting. We have sought to significantly improve the robustness of the single-chain Fv (scFv) library construction step by overcoming the technical inefficiencies frequently encountered during the PCR-mediated assembly of scFvs from the discrete heavy and light V-domain repertoires. Using a novel primer set designed to provide maximum amplification coverage of the known germ-line V-domain repertoire, we have exploited the potential of the in vivo homologous gap-repair apparatus of Saccharomyces cerevisiae to assemble intact scFvs directly from co-transformed PBMC-derived VH, VL, and linearized vector component fragments. We have successfully applied this three-fragment assembly strategy to construct a large (>10(9)) scFv yeast display library from the ascites immune repertoire of ovarian cancer patients and validated the approach by applying FACS-based sorting to readily isolate scFvs that recognize various tumor marker antigens (TMAs). It is expected that this simplified construction method may find general utility, both for de novo scFv library construction and for subsequent combinatorial affinity maturation manipulations that require more than two fragments.

    This study examined the effects of dietary DL-2-hydroxy-4(methylthio)butanoic acid (DL-HMTBA) supplementation on growth performance, antioxidant capacity, and ascites syndrome (AS) in broilers reared at low ambient temperature (LAT) from 7 to 28 days of age. Eight hundred 7-day-old broilers were randomly assigned to two ambient temperatures (LAT and normal ambient temperature [NAT]), four supplemental DL-HMTBA levels (0.17, 0.34, 0.51, and 0.68 %) of the basal diet in a 2 × 4 factorial arrangement (ten replicate pens; ten birds/pen). LAT and NAT indicate temperatures of 12-14 and 24-26 °C in two chambers, respectively, and broilers were reared at these temperatures from 7 to 28 days of age. LAT significantly decreased body weight gain ( P AOC) at 21 days ( P = 0.001, 0.015) and 28 days ( P = 0.017, 0.010) and increased feed conversion ratio (FCR) ( P < 0.001), serum malondialdehyde (day 21, P = 0.000) and protein carbonyl Level (day 14, P = 0.003; day 21, P = 0.035). As for incidence of AS, there were significant effects of LAT on red blood cell (RBC) count ( P < 0.05), hematocrit (HCT) ( P < 0.05), and the right to total ventricular weight ratio (RV/TV) at 21 days ( P = 0.012) and 28 days ( P = 0.046). Supplementation of DL-HMTBA markedly decreased RV/TV at day 28 ( P = 0.021), RBC (day 21, P = 0.008), HCT (day 21, P < 0.001), mean cell hemoglobin (day 14, P = 0.035; day 21, P = 0.003), and serum protein carbonyl level (day 21, P = 0.009), while significantly increased serum GSH content (day 14, P = 0.022; day 28, P = 0.001), SOD and GSH-Px activities at 21 days of age ( P < 0.001 and P = 0.037). The optimal supplemental DL-HMTBA levels in basal diet of broilers aged from 7 to 28 days under low or normal temperatures were similar, so the authors recommended supplemental of DL-HMTBA level was 0.46 %.

    The aim of present study was to verify the in vitro antitumor activity of a ruthenium complex, cis-(dichloro)tetraammineruthenium(III) chloride (cis-[RuCl(2)(NH(3))(4)]Cl) toward different tumor cell lines. The antitumor studies showed that ruthenium(III) complex presents a relevant cytotoxic activity against murine B cell lymphoma (A-20), murine ascitic sarcoma 180 (S-180), human breast adenocarcinoma (SK-BR-3), and human T cell leukemia (Jurkat) cell lines and a very low cytotoxicity toward human peripheral blood mononuclear cells. The ruthenium(III) complex decreased the fraction of tumor cells in G0/G1 and/or G2-M phases, indicating that this compound may act on resting/early entering G0/G1 cells and/or precycling G2-M cells. The cytotoxic activity of a high concentration (2 mg mL(-1)) of cis-[RuCl(2)(NH(3))(4)]Cl toward Jurkat cells correlated with an increased number of annexin V-positive cells and also the presence of DNA fragmentation, suggesting that this compound induces apoptosis in tumor cells. The development of new antineoplastic medications demands adequate knowledge in order to avoid inefficient or toxic treatments. Thus, a mechanistic understanding of how metal complexes achieve their activities is crucial to their clinical success and to the rational design of new compounds with improved potency.

    Full Text Available Como em outros seres vivos, também nas células das aves ocorre a síntese das proteínas de baixo peso molecular (Hsp, cujo aumento é induzido sob condições de estresse. As Hsps têm um papel importante na manutenção da integridade celular, questiona-se o seu envolvimento no mecanismo de proteção celular de órgãos alvos na ocorrência da síndrome ascítica (SA. Este trabalho objetivou avaliar a temperatura corporal e os níveis da Hsp70 no coração e pulmão de frangos de corte Hubbard (sensível à SA e caipira de pescoço-pelado (resistente, criados em termoneutralidade (25°C e frio (16°C entre 10 e 45 dias de idade. Foram utilizados 192 pintos machos, 96 de cada linhagem. Não houve mortalidade por SA nas aves caipiras. Nas aves Hubbard, a mortalidade devida à SA foi de 4% e 41% em ambiente termoneutro e frio, respectivamente. Em ambiente frio, a temperatura corporal das aves Hubbard foi menor que a das caipiras. A temperatura corporal e o nível de Hsp70 do coração das aves Hubbard diminuíram com o aumento da idade, mas não nas aves caipiras, os quais se mantiveram constantes, inclusive a Hsp70 do pulmão. Independente da idade ou da temperatura, o nível de Hsp70 no pulmão das aves caipiras era superior ao das aves Hubbard. Em relação às aves Hubbard, as caipiras são homeotérmicas mais competentes e apresentam uma maior indução de Hsp70 nos órgãos primariamente afetados na SA, mas este não parece ser o sistema de proteção contra SA, a qual as aves de pescoço pelado são resistentes.Similar to other living animals, the cells of the birds also synthesize small proteins (heat shock protein, Hsp, which increasing levels can be induce by stress. The Hsp have a relevant function in maintaining the integrity of the cell, and we question if they are involved in the mechanism of the cellular protection of target organs affected by ascites syndrome (AS.

    Full Text Available Pasteurella multocida, a zoonotic agent transmitted by canines and felines, has been very rarely reported to cause bacterial peritonitis in humans. Pasteurella multocida peritonitis is associated with high mortality even with appropriate treatment, therefore its early recognition is essential. We report a case of Pasteurella multocida peritonitis following cat scratch in a patient with Child Pugh Class C alcoholic cirrhosis, culminating in multiple organ failure and death.

    1989-04-01

    Full Text Available To study the mechanism of DNA excision repair, a DNA repair system employing permeable mouse sarcoma (SR-C3H/He cells was established and characterized. SR-C3H/He cells were permeabilized with a 0.0175% Triton X-100 solution. The permeable cells were treated with 1 mM ATP and 0.11 mM bleomycin, and then washed thoroughly to remove ATP and bleomycin. Repair DNA synthesis occurred in the bleomycin-damaged, permeable SR-C3H/He cells when incubated with ATP and four deoxyribonucleoside triphosphates. The repair nature of the DNA synthesis was confirmed by the BrdUMP density shift technique, and by the reduced sensitivity of the newly synthesized DNA to Escherichia coli exonuclease III. The DNA synthesis was optimally enhanced by addition of 0.08 M NaCl. Studies using selective inhibitors of DNA synthesis showed that aphidicolin-sensitive DNA polymerase (DNA polymerase alpha and/or delta and DNA polymerase beta were involved in the repair process. The present DNA repair system is thought to be useful to study nuclear DNA damage by bleomycin, removal of the damaged ends by an exonuclease, repair DNA synthesis by DNA polymerases and repair patch ligation by DNA ligase(s.

    A 75-year old man had been diagnosed at 42 years of age as having polycythemia vera and had been monitored at another hospital.Progression of anemia had been recognized at about age 70,and the patient was thus referred to our center in 2008 where secondary myelofibrosis was diagnosed based on bone marrow biopsy findings.Hematemesis due to rupture of esophageal varices occurred in January and February of 2011.The bleeding was stopped by endoscopic variceal ligation.Furthermore,in March of the same year,hematemesis recurred and the patient was transported to our center.He was in irreversible hemorrhagic shock and died.The autopsy showed severe bone marrow fibrosis with mainly argyrophilic fibers,an observation consistent with myelofibrosis.The liver weighed 1856 g the spleen 1572 g,indicating marked hepatosplenomegaly.The liver and spleen both showed extramedullary hemopoiesis.Myelofibrosis is often complicated by portal hypertension and is occasionally associated with gastrointestinal hemorrhage due to esophageal varices.A patient diagnosed as having myelofibrosis needs to be screened for esophageal/gastric varices.Myelofibrosis has a poor prognosis.Therefore,it is necessary to carefully decide the therapeutic strategy in consideration of the patient's concomitant conditions,treatment invasiveness and quality of life.

In EHR2/VP16, the steady......M. ATPase activity was slightly stimulated by daunorubicin, whereas vinblastine, verapamil, and cyclosporin A had no effect. In conclusion, development of resistance to VP16 in EHR2 is accompanied by a significant reduction in topoisomerase II (alpha and beta) and by increased expression of MRP mRNA (20......-fold). MRP displays several points of resemblance to P-glycoprotein in its mode of action: 1) like P-glycoprotein, MRP causes resistance to a range of hydrophobic drugs; 2) MRP decreases drug accumulation in the cells and this decrease is abolished by omission of energy; and 3) MRP increases efflux of...

    rate constant for the initial taurine uptake was reduced by 45% (high-affinity system) and 49% (low affinity system) in the resistant subline whereas the affinity of the transporters to taurine was unchanged. By immunoblotting we identified 3 TauT protein bands in the 50-70 kDa region. A visible...... Ehrlich cells increased compared to the parental fibroblasts. It is concluded that the reduced taurine uptake in resistant Ehrlich cells reflects a down regulation of the taurine transporter at the mRNA and protein level and it is most probably not related to P-gp overexpression....

    Rapidly increasing malignant neoplastic disease demands immediate attention. Several dietary compounds have recently emerged as strong anti-cancerous agents. Among, Bromelain (BL), a protease from pineapple plant, was used to enhance its anti-cancerous efficacy using nanotechnology. In lieu of this, hyaluronic acid (HA) grafted PLGA copolymer, having tumor targeting ability, was developed. BL was encapsulated in copolymer to obtain BL-copolymer nanoparticles (NPs) that ranged between 140 to 281nm in size. NPs exhibited higher cellular uptake and cytotoxicity in cells with high CD44 expression as compared with non-targeted NPs. In vivo results on tumor bearing mice showed that NPs were efficient in suppressing the tumor growth. Hence, the formulation could be used as a self-targeting drug delivery cargo for the remission of cancer. PMID:27287553
