A roentgenological and endoscopical study is presented of the stomach and duodenum in 66 patients during remission and in 22 patients during exacerbation of ulcer disease from 6 months up to 5 years after organsaving operations using vagotomy. In the majority of patients the stomach was characterized by a large gas bubble, cascade-like torsion, deformation of the antral portion and duodenal bulb. In some patients thickenings of the gastric antral mucosa were noted. An endoscopically confirmed ulcer was revealed roentgenologically only in 50% of patients

With the purpose of improvement of diagnosis of induced gastric ulcer were examined 11 patients who took aggressive agents for simulation of gastric ulcer and 33 patients who took pseudo-aggressive agents. Observables, conduced diagnosis of local chemical burn of mucous coat of stomach during initial 6 days after taking aggressive agents. Stages of ulcerous process, resulting from local chemical burn of mucous coat of stomach, coressponds to real gactric ulcer. Gelatin capsule using as a container for delivery of aggressive agents, melts in stomach in 5-6 minutes after taking. Independent from body position, mucous coat of greater curvature of the stomach is damaged. It is impossible to simulate duodenal bulb ulcer using the gelatine capsule or ball made of breadcrumb. The last method of delivery of aggressive agent can damage the small intestine because of uncontrollability of the place of breaking the ball.

To observe the effects of electroacupuncture (EA) at stomach meridian acupoints on expression of oxidation damage factors in serum and gastric mucosal cells in rats with gastric ulcer, and to explore the mechanism of EA at stomach meridian acupoints for oxidative damage in rats with gastric ulcer. Forty clean-grade SD rats were randomly divided into a normal group, a model group, a stomach meridian group and a gallbladder meridian group, ten rats in each one. Except the normal group, rats in the remaining groups were applied the restraint-cold stress method to establish the model of gastric ulcer. Rats in the normal group and model group received no treatment; rats in the stomach meridian group were treated with EA at "Liangmen" (ST 21) and "Zusanli" (ST 36); rats in the gallbladder meridian group were treated with EA at "Riyue" (GB 24) and "Yanglingquan" (GB 34). The EA was given for 30 min, once a day for 7 days totally. The change of gastric mucosal morphology was observed by routine light microscope; enzyme linked immunosorbent assay was used to detect the expressions of malondialdehyde (MDA), glutathione peroxidase (GSH-px) and tumor necrosis factor-α (TNF-α), interleukin-2(IL-2), interleukin-6(IL-6) in serum and gastric mucosal cells of rats. After treatment, compared with the model group, the gastric mucosal damage index was decreased in the stomach meridian group and gallbladder meridian group (both P stomach meridian group (all P stomach meridian group rats ( P stomach meridian acupoints is likely to inhibit the expressions of oxidative damage factors to promote the repair of gastric mucosal injury, which indicates the correlation between meridians and zang-fu .

To define influence of the comorbidity diseases and risk factors of development of the combined peptic ulcer of a stomach and duodenum. As a result of carried-out poll and inspection 250 patients with an exacerbation of a peptic ulcer were surveyed. Patients were distributed in 3 groups of observation depending on localization of ulcerative process. At all surveyed questioning was carried out, data on hereditary load, smoking, alcohol intake, existence of somatopathies were specified, clinic-morphological implications of a peptic ulcer were studied. The peptic ulcer of a stomach is characteristic for women (72.1%) and develops mainly aged from 45 till 59 years (60.3%). Peptic ulcer of duodenum men (76.3%) suffer mainly, the debut is the share in most cases of age from 18 to 44 years (79.1%). The combined canker of a stomach and duodenum meets at males (61.2%) more often, is initially involved in process ulcerogenesis by duodenum generally aged from 30 till 44 years (64.2%), accession of a canker of a stomach happens is delayed (at 38.8% within 16 and more years). In the analysis of risk factors at patients with the combined peptic ulcer of a stomach and duodenum depending on existence or absence specific to this category of patients of a background from such comorbidity diseases as IBS, HOBL and widespread osteochondrosis taped that larger prevalence of smoking (100%) and as the use (50%) and the excessive use (50%), alcohol are characteristic for the patients having a high comorbidity (a combination of three above nosologies). The greatest interest in respect of possible communication with formation of the combined peptic ulcer of a stomach and duodenum is represented by IBS, HOBL and osteochondrosis. And major factors of risk were smoking, the excessive alcohol intake, the burdened heredity.

We report a case of lipoma in the antrum of the stomach which prolapsed into the duodenal bulb and caused a duodenal ulcer, which was speculated to have been induced by the friction of its tip against the duodenal mucosa. Although the duodenal ulcer healed after the administration of a proton pump inhibitor, the symptoms of epigastric discomfort continued, which was suggested to be due to the prolapse. Therefore, a laparoscopic operation was conducted. The incidence of lipoma of the stomach is rare, and cases of its prolapse into the duodenum are few. Furthermore, it is extremely rare for it to cause a duodenal ulcer. Because these features made this case clinically interesting, we report it here.

Full Text Available It was fixed, that development of atophanum-carbacholimun ulcer of the gastroduodenal zone invoked various changes of secretory activity of the stomach. The changes directly depend on a progress of pathological process. As this takes place the reaction of stomach secretory glands varies under the stimulation with histamine: the decrease of stomach secretory glands’ work capacity till 10th day and its increase after 10–15th day were observed. Disorders of the glands’ ultradian rhythms at initial stages of modeling of gastrointestinal nervous regulation disturbances testify to dependence of periodic activity of gastrointestinal tract on resistance of regulatory mechanisms correlation.

By using the goaloriented X-ray study along with endoscopy in over 600 patients with peptic ulcer with its site in the stomach (PUSS) both for its primary diagnosis and during its treatment and in various posttreatment periods (from 3 to 6 years), the author supposes that X-ray due to its characteristic three-dimensional image of the stomach will provide comprehensive syndrome information as to its benign ulcerations. The author failed to observe signs of their malignancy in none of more than 600 long-term follow-ups, which made him state that appropriate correctives approaches to this problem should be applied. Active use of X-ray techniques to verify the efficiency of the therapy performed eliminates the bulk of problems in the diagnosis of benign and malignant gastric ulcerations, especially those associated with the differentiation of a postulcerous scar and early gastric cancer. 73 refs., 7 figs

Proton pump inhibitors (PPIs) are widely used to treat hyperacid secretion and stomach ulcers. The study investigated the anti-secretory and anti-ulcer effects of esomeprazole, the S-isomer of omeprazole on dimaprit, histamine and dibutyryl adenosine 3, 5 cyclic monophosphate (dbcAMP)-evoked gastric acid secretion, acidified ethanol (AE) and indomethacin (INDO)-induced haemorrhagic lesions and on prostaglandin E2 (PGE2) level in the rat in vivo and rabbit in vitro preparations. The effect of omeprazole was also investigated for comparison. Dimaprit-induced acid secretion was significantly (P stomach tissue homogenate. The results show that esomeprazole and omeprazole were equally effective against gastric haemorrhagic lesions induced by either AE or INDO and in inhibiting dimaprit-, dbcAMP- and histamine-induced gastric acid secretion in the rat and rabbit stomach both in vivo and in vitro. The gastro-protective effect of esomeprazole was found to be proportional to the bound PGE2 levels in the glandular area of the stomach.

Background. Marginal ulcer is a well-known complication after gastrectomy. Its bleeding can be severe, but the severity has rarely been reported. We aim to evaluate the clinical outcomes of marginal ulcer bleeding (MUB) as compared to peptic ulcer bleeding (PUB) with nonoperated stomach. Methods. A consecutive series of patients who had nonvariceal upper gastrointestinal bleeding and admitted to the hospital between 2005 and 2011 were retrospectively analyzed. A total of 530 patients were enrolled in this study, and we compared the clinical characteristics between 70 patients with MUB and 460 patients with PUB. Results. Patients with MUB were older (mean age: 62.86 ± 10.59 years versus 53.33 ± 16.68 years, P = 0.01). The initial hemoglobin was lower (8.16 ± 3.05 g/dL versus 9.38 ± 2.49 g/dL, P = 0.01), and the duration of admission was longer in MUB (7.14 ± 4.10 days versus 5.90 ± 2.97 days, P = 0.03). After initial hemostasis, the rebleeding rate during admission was higher (16.2% versus 6.5%, P = 0.01) in MUB. However, the mortality rate did not differ statistically between MUB and PUB groups. Helicobacter pylori-positive rate with MUB was lower than that of PUB (19.4% versus 54.4%, P = 0.01). Conclusions. Clinically, MUB after gastrectomy is more severe than PUB with nonoperated stomach. Infection with H. pylori might not appear to play an important role in MUB after gastrectomy. PMID:23304127

This chapter explains the procedure of ethanol-induced ulcer to check the protective effect of drugs over induced ulcer in rats. Ulcer is defined as the erosion in the lining of the stomach or duodenum and is caused by the disruptions of the gastric mucosal defence and repair systems. Ulceration of stomach is called gastric ulcer and that of duodenum is called duodenal ulcer and together peptic ulcer. In clinical practice, peptic ulcer is one of the most prevalent gastrointestinal disorders, which commonly occurs in developed countries.

Influence of cattle cord blood fraction (below 5 kD) on lipid peroxidation product content and alkaline phosphatase activity-in peripheral blood was studied on the experimental subchronic stomach ulcer model in rats. It has been shown that the fraction administrations normalize thiobarbituric-active product content and alkaline phosphatase activity in blood, which testifies to decreasing inflammatory reaction in the mucous membrane of the stomach. The fraction administrations accelerate the processes of regeneration of the mucous membrane of the stomach up to complete healing of ulcer defects. Cord blood fraction below 5 kD from cattle possesses antiulcer activity which is analogous to the actovegin activity. It has been shown by gel-penetrating chromatography that the pattern of cord blood fraction low molecular substances is different from the actovegin pattern both qualitatively and quantitatively.

There were four types of stomach contour included eutonic, hypotonic, steerhorn, and cascade. The aim of this study is to clarify relationship between incidence of stomach cancer and contour variation of the stomach. Double- contrast upper gastrointestinal study was performed in 1,546 patients, who had dyspepsia or other gastrointestinal tract symptoms. The radiographs were classified into the four types including eutonic, hypotonic, steerhorn, and cascade according to stomach contour in relation to body build. We also reviewed pathologic reports on endoscopic biopsy or surgical specimen. We studied the presence of relationship between incidence of stomach cancer and variation of stomach contour. We also examined the incidence of gastritis and gastric ulcer to the stomach contour variation. Of total 1,546 patients, eutonic stomach were 438(28.3%), hypotonic 911(58.9%), steerhorn 102(6.5%) and cascade 95(6.2%). Stomach cancer was found in 139(31.7%) of 438 eutonic stomachs, in 135(14.8%) of 911 hypotonic, in 42(41.2%) of 102 steerhorn, and in 24(36.9%) of 95 cascade (P=0.001). In hypotonic stomach, the incidence of stomach cancer was lower compared to the other three types significantly (p<0.05). Gastritis or gastric ulcer was found in 146(33.3%) of eutonic stomach, in 293(32.1%) of hypotonic, in 36(35.2%) of steerhorn, and in 26(27.3%) of cascade (p=0.640). In conclusion, gastric contour variation seems to be a factor affecting development of stomach cancer. The patients with hypotonic stomach may have lower incidence of stomach cancer than that of the other types. There was no relationship between the contour and gastric ulcer

Gastric ulcer and its recurrent lesion were successively induced by acetic acid and interliukin1-beta (IL-1beta), and the model rats were divided into the sham operation group, the model group, the omeprazole (correction of omepraxole) group and the JYG group to observe the state of chronic inflammatory cell, neutrophil count, NF-kappaBmRNA and protein expression in stomach tissue. On the 16th and 92th day after administration, the increase of chronic inflammatory cell, neutrophil, NF-kappaBmRNA and protein expression in the model group was more significant than those in the sham operated group (P ulcer induced by acetic acid. JYG may suppress inflammatory reaction by inhibiting the activation and expression of NF-kappaB in stomach tissue, which may be one of the mechanisms of JYG in preventing the recurrence of gastric ulcer.

1984-01-01

Some potentialities of the X-ray and endoscopic methods in the recognition of early stomach cancer are analysed. Both methods are provided by a roentgenotogist. Of 396 operated patients with stomach cancer, early forms were detected in 78 which is equal to 8% of the detected number and 19.7% of the operated cancer pasients. Two macroscopic forms of early cancer were detected: cancer with ulceration (erosion-ulcerative form) and polypoidcancer. The first form is interpreted as primary-ulcerative cancer, malignant ulcers and cancer in the form of erosions, the second one as polyps, polypoid and patchlike cancer, malignant polyps. X-ray changes were detected in 80% of the patients, in the rest of 20% by the endoscopic method only. With the help of the roentgenological and endoscopic methods (without cytological examination) one cannot be sure of accurate differential diagnosis between malignant and benign variants of ulcerations and polypoid changes in early cancer. The potentialities of the X-ray method ir the detection of ulcerative and polypoid changes of the stomach make it possible to improve it, though under a strict condition of performing subsequent obligatory endoscopy and getting tissue specimens for biopsy. The organization of the common roentgenoendoscopic centers is found appropriate

The article deals with evaluation findings of diagnostic possibilities of gastroscintigraphy in assessment of motoric evacuatory function of the stomach in case of pathology of various origin. Gastroscintigraphy was conducted for 122 patients (56 men and 66 women) aged from 18 to 72 with different gastroduodenal pathology (functional dyspepsia, chronic gastritis, chronic cholecystitis, ulcer of the stomach and duodenum. Radiopharmaceutical agent 99 mTc-pertechnetate with activity of 1 MBq/kg was applied. Impaired motoric evacuatory function of the stomach was observed in 63 patients: regarding hypotonic type in most patients with functional dyspepsia (13.3%) and with chronic gastritis (19.8%); according to hypertonic type - 32 patients, mainly with functional dyspepsia (9.8%) and gastric ulcer (6.6%). Increased motoric evacuatory function of the stomach was revealed in 40 patients: with functional dyspepsia (14.8%) and in gastric ulcer (16.4%). The gastroesophageal reflux was observed in 59 patients and duodenogastric one - in 36 patients. Therefore, gastroscintigraphy in assessment of motoric evacuatory function of the stomach can completely replace X-ray examination.

Incidence of gastric ulcer is high in almost all countries of the world. On the development and course of the disease affect the state acid- and enzymes production stomach, immune status. The purpose was to determine the presence and power of correlative links secretory activity of the stomach and immune changes in the peripheral blood during exacerbation of ulcer disease stomach. Surveyed in obtaining informed consent 42 patients with gastric ulcer in the acute phase prior to the eradication and antisecretory therapy and 40 healthy volunteers. On the state of function acid- and enzymes production of the gastric mucosa judged by the results of a 2-hour intragastric pH-metry and serum concentration pepsinogen, gastrin before the start of active treatment. Immunophenotype lymphocytes on CD-antigens (CD3, CD4, CD8, CD16, CD19, CD45, CD56) was measured by immunofluorescence, levels immunoglobulin isotype M, G, A, E - ELISA method. When short-term intragastric pH-metry of the stomach hyperacidity patients recorded 6.7 times more likely than healthy, normacidity - 12.3 times less. Reduction of acid production was observed up to 8.6 times more, indicating the development of mucosal atrophy. Basal pH in the antrum was lower by 54.5% than in the control group, with stimulation increased by 33.6%, but remained lower than the values of healthy individuals by 48.7%. When ELISA amount pepsinogen patients showed significant increase in serum levels of PG-I relative to the control group at 33.4%, PG-II - 52%. In assessing the immune status of patients were identified changes in system phagocytes, cellular and humoral links, most pronounced for severe current peptic ulcer disease. The results indicate the presence of positive and negative correlative links mild to moderate force between indicators of secretory activity of gastric mucosal innate and adaptive immunity in patients with acute exacerbation of peptic ulcer disease.

The estimated volume of meal in the stomach 30 mins after sup(113m)In-DTPA administration was determined in patients with gastric ulcer and normal controls by 1) relating counts in the stomach to those in the whole field of view of the gamma camera and 2) aspirations. In the normal controls there was no significant difference between the two methods but in the gastric ulcer patients, the gamma camera method predicted significantly more meal in the stomach than was recovered by aspiration. It was suggested that the large low lying stomach found in gastric ulcer disease causes extensive overlap of the small bowel and invalidates measurements of gastric emptying made by a gamma camera.

To develop a new medical technology for the spa-and-health resort-based treatment of the patients presenting with frequently recurring erosive and ulcerative lesions in the oesophagus, stomach, and duodenum in the phase of subsiding exacerbation. A total of 100 patients presenting with frequently recurring erosive and ulcerative lesions in the oesophagus, stomach, and duodenum in the phase of subsiding exacerbation were available for the examination that included detailed investigations of the clinical picture, characteristics of the immune status, and psychological testing before and after a course of the spa-and-health resort-based treatment. The effectiveness of two therapeutic modalities was evaluated. One of them (control) prescribed to 50 patients consisted of standard antiulcer pharmacotherapy in combination with Essentuki Novaya drinking mineral water and carbon dioxide mineral baths, the other given to 50 patients included radon baths instead of carbon dioxide mineral baths. The combined application of drinking mineral waters, radon baths, and standard antiulcer pharmacotherapy produced the most conspicuous clinical effect in the framework of spa-and-health resort-based rehabilitation of the patients presenting with frequently recurring erosive and ulcerative lesions in the oesophagus, stomach, and duodenum in the phase of subsiding exacerbation as confirmed by positive dynamics of their psychoemotional status in 97.7% of the cases, regression of pain syndrome (91.5%), and improvement of humoral and cellular immunity (94%). An important result of the spa-and-health resort-based rehabilitation is the intensification of the reparative processes in gastroduodenal mucosa responsible for the healing of ulcers and erosions in 94.7% of the patients. The spa-and-health resort-based rehabilitation is a pathogenetically sound and efficacious approach to the management of the patients presenting with frequently recurring erosive and ulcerative lesions in the

Histological changes in the canine stomach following massive electron beam irradiation

The histologic changes induced by irradiation of the stomachs of dogs were examined one hour to nine months after irradiation. The irradiated area of the stomach progressed to ulcer formation by way of hyperemia and erosion; on the other hand, there were simultaneous signs of recovery. Regenerating epithelium appeared during the first week and migrated from the surface adjacent to the ulcer to the center of the ulcer. Subsequently the muscularis mucosae extended, and then the submucous coat was repaired. Regeneration of the nerve fibers around the muscularis mucosae seemed to reach its maximum three weeks after irradiation. These proliferating nerves degenerated with deepening of the radiation ulcer, but they were unexpectedly radioresistant and protruded from the surface of the ulcer into the necrotic surrounding tissues. It is concluded that the effect of irradiation on the alleviation of the pain of stomach cancer is not due to the degeneration of the nerves but to elimination of the stimulation of nerves on account of the radiation effect on the cancer cells themselves.

Full Text Available Radioembolization (RE is a selective internal radiation therapy (SIRT delivering targeted, high-dose, intra-arterial radiation directly to the vascular supply of liver tumors. Complications can occur due to aberrant deposition or migration of radiation microspheres into nontarget locations, including normal hepatic parenchyma, lungs, pancreas, and upper gastrointestinal (UGI tract. We report a case of gastric ulcers due to yttrium-90 (90Y seed migration to the stomach to alert clinicians to this rare cause of gastric injury. A 57-year-old woman with stage IV breast cancer with liver and lung metastases presented to the hospital with 2 months of worsening nausea and vomiting. Two months prior, she had received SIRT with 90Y microspheres without complications. Upper GI endoscopy showed diffuse gastritis and extensive antral ulceration. Biopsies revealed black, spherical foreign bodies, consistent with 90Y microspheres, documenting radiation injury. Radiation-induced UGI ulceration is caused by direct radiation injury from beta-radiation. Delay in diagnosis may be due to the nonspecificity of symptoms and temporal delay of symptom onset from SIRT, which was 2 months in our patient. Also, complaints may be attributed erroneously to adjuvant chemotherapy or widespread metastatic disease. Clinicians must consider radiation-associated toxicity in any SIRT-treated patient developing abdominal symptoms.

We studied 24-h rhythms of acid production and alkalization in 30 patients with duodenal ulcer (DU) and 30 healthy subjects using upper endoscopic examination and computer intragastric pH-metry. Gastric acid production was higher in DU patients and was more intensive in the daytime than at night. Healthy subjects had low and monotonous acid production. In DU decompensation of alkalization in the antral stomach and suppression of duodenogastric reflux is total. In healthy subjects antrum alkalization is more evident and intensive at night due to, among other causes, duodenogastric reflux.

The stomach is traditionally regarded as a hollow muscular sac that initiates the second phase of digestion. Yet this simple view ignores the fact that it is the most sophisticated endocrine organ with unique physiology, biochemistry, immunology and microbiology. All ingested materials, including our nutrition, have to negotiate this organ first, and as such, the stomach is arguably the most important segment within the GI tract. The unique biological function of gastric acid secretion not only initiates the digestive process but also acts as a first line of defence against food-borne microbes. Normal gastric physiology and morphology may be disrupted by Helicobacter pylori infection, the most common chronic bacterial infection in the world and the aetiological agent for most peptic ulcers and gastric cancer. In this state-of-the-art review, the most relevant new aspects of the stomach in health and disease are addressed. Topics include gastric physiology and the role of gastric dysmotility in dyspepsia and gastroparesis; the stomach in appetite control and obesity; there is an update on the immunology of the stomach and the emerging field of the gastric microbiome. H. pylori-induced gastritis and its associated diseases including peptic ulcers and gastric cancer are addressed together with advances in diagnosis. The conclusions provide a future approach to gastric diseases underpinned by the concept that a healthy stomach is the gateway to a healthy and balanced host. This philosophy should reinforce any public health efforts designed to eradicate major gastric diseases, including stomach cancer. PMID:26342014

The goal of the presented work was the research of signal transduction mechanism in the rat gastric parietal cells under stomach ulcer conditions. In these cells activation of adenylate cyclase (increase of cAMP level and proteinkinase A activity) and phosphoinositide (increases [Ca2+]i; cGMP and phoshatidylinocitole levels; proteinkinase C, proteinkinase G, and calmodulin-dependent-proteinkinase activity) of signals pathway was shown. An increase of plasma membrane phospholipids (PC, PS, PE, PI, LPC) level was shown. Under conditions of influence of the stress factor the membran enzymes activity (H+, K+ -ATPase, 5'-AMPase, Na+, K+ -ATPase, Ca2+, Mg2+ -ATPase and H+, K+ -ATPase) was considerably increased. The intensification of lipid peroxidation processes in rats was demonstrated.

Background This study aimed to evaluate the effects of the position of an acetic acid-induced gastric ulcer and the effects of prokinetic drugs on gastric emptying. Materials and Methods Male Sprague-Dawley rats were used in this study. Acetic acid ulcers were induced either in the region between the fundus and pylorus on the anterior wall of the stomach or in the glandular region on the greater curvature of the stomach to determine whether there were regional differences in the effect of the ulcers. Gastric emptying was evaluated with a breath test using [1- 13 C] acetic acid. In addition, the effects of the prokinetic drugs, metoclopramide and mosapride, on gastric emptying were also evaluated. Results Acetic acid induced ulcers in the region between the fundus and pylorus on the anterior wall of the stomach significantly delayed gastric emptying as compared with control rats, but not the acetic acid induced ulcers in the glandular region on the greater curvature of the stomach. Metoclopramide and mosapride did not improve the delayed gastric emptying even at doses that enhanced gastric emptying in normal rats. Conclusion These findings show that gastric emptying is influenced by the position of the ulcer and the region between the fundus and pylorus on the anterior wall plays an important role in gastric emptying. Moreover, it was found that metoclopramide and mosapride do not improve the delayed gastric emptying caused by acetic acid ulcers induced on the anterior wall in the region between the fundus and pylorus.

Full Text Available Background: Stomach mucosal wall erosion is caused by the imbalance of the aggressive factors and mucosal defensive factors due to the common causes such as the side effect of consuming non-steroidal anti-inflammatory drugs. Field mint (Menthaarvensis leaves have been used as an alternative option to cure and prevent the gastric problems. The aim of this study was to analyze the protective effect of Field mint leaves infusion in reducing stomach ulcer in rats induced by Aspirin. Methods: The experimental study was conducted at Histology Laboratory of Faculty of Medicine, Universitas Padjadjaran, Bandung. Sixteen rats were divided into 4 groups randomly: group I (control negative group, group II (control positive group, given 90mg/day Aspirin, group III (the treatment group, given 5cc of Field mint leaves infusion and 90 mg Aspirin and group IV (the treatment group, given 5.6µg of Misoprostol and 90 mg Aspirin. Mucosal wall erosions were determined by using microscope. Data were analyzed using non-parametric Kruskal-Wallis test and Mann-Whitney U-test (CI 95% and p-value<0.05 Results: Group II had high score of mucosal wall erosions after given only aspirin. In group III and IV, the score of mucosal wall erosions were low. However there was no difference in score of mucosal wall erosions between group III-IV (p<0.05 Conclusions: Field mint (Menthaarvensis leaves infusion is able to prevent stomach mucosal wall erosions induced by Aspirin as misoprostol does.

A study was made of the X-ray picture of the stomach postulcer scar in correlation with fibrogastroscopy in 39 patients. The X-ray picture was characterized by considerable polymorphism and at the same time it was difficult to single out pathognomonic features. For specified diagnosis and differentiation the detection of the postulcer scar must become a multifaceted roentgenoendoscopic problem. Stomach ulcers may scar, sometimes with the complete regeneration of the mucosa relief, however their recurrences can develop in the zone of the postulcer scar

The possibilities of roentgenoendoscopic diagnostics of stomach syphilis are demonstrated by disease cases. Three forms of the stomach syphilis: tumor-like, infiltration and ulcerous ones are identified both roentgenological and endoscopic. Any infiltration process in the stomach of a young patient determined roentgenological should be reasoned as a sign of alterness relative to the syphilis. To perform endoscopic diagnosis of the stomach syphilis is easier than roentgenological one. The final syphilis diagnosis is impossible without blood test [ru

It is shown that the role of roentgenological investigation when detecting changes, which may indicate cancer of the 1st stage, has substantially increased. However, due to frequent nonspecificity of x-ray and endoscopic symptoms at cancers of the 1st stage, benign polyps and ulcers, as well as due to mucous membrane reconstruction under several forms of gastritis, the final diagnosis may be ascertained only using a complex investigation (roentgenological, endoscopic with obligatory taking of biopsy from several places with subsequent cytologic and histologic

This research was conducted to evaluate the hypothesis that gastric ulcers caused by the NSAID diclofenac sodium (DCF) can be prevented by the soluble epoxide hydrolase inhibitor TPPU. Mice were administered a single dose of 10, 30 or 100mg/kg of DCF. Once an ulcerative dose of DCF was chosen, mice were pretreated with TPPU for 7days at 0.1mg/kg to evaluate anti-ulcer effects of the sEH inhibitor on anatomy, histopathology, pH, inflammatory markers and epithelial apoptosis of stomachs. Diclofenac caused ulceration of the stomach at a dose of 100mg/kg and a time post dose of 6h. Ulcers generated under these conditions were associated with a significant increase in the levels of TNF-α and IL-6 in serum and increased apoptosis compared to control mice. Pretreatment with TPPU resulted in a decrease of ulceration in mice treated with DCF with a significant decrease in the level of apoptosis, TNF-α and IL-6 in the serum in comparison to diclofenac-treated mice. TPPU did not affect the pH of the stomach, whereas omeprazole elevated the pH of the stomach as expected. A similar anti-ulcer effect was observed in sEH gene knockout mice treated with DCF. The sEH inhibitor TPPU decreases the NSAID-induced stomach ulcers. Copyright © 2017 Elsevier Inc. All rights reserved.

Full Text Available Extract of Echinops persicus is traditionally used for a long time in Iran for treatment of cough and constipation. This extract is produced by activity of bug (Situphilus spp. on the plant. We documented its anti-tussive effect in rats in our previous study.The aim of this study was to assess the anti-ulcer effect of Echinops persicus in an animal model. In this study we evaluated anti-ulcer effect of Echinops persicus by Shay's method in rats. In 3 groups of rats, pylorus was ligatured under anesthesia. The rats were euthanized after 19 hours later and number and level of ulcer in stomach was measured. In group 2 the extract was orally administered 45 minutes before pyloric ligature, and in group 3, it was administered intraperitoneally 20 minutes before pyloric ligature. The number of ulcers in stomach was significantly low in group 2 (P = 0.01 and 3 (P = 0.037 in comparison with group 1. The level of ulcer was significantly decreased in group 2 (P = 0.047 with comparison to group 1. We conclude that, Echinops extract can exhibit potentially cytoprotective and anti-ulcer activity.

E-mail: radiovet@ufrrj.br The equine gastric ulcer syndrome (EGUS includes all symptomatic or asymptomatic cases of erosions, ulcers, gastritis, gastric emptying disorders, duodenitis, duodenal ulcers and complications of these disorders. Occupies a prominent place in the equine clinic where you can go for the death of the animal. Ultrasonography of the stomach is indicated when the animals showed clinical signs of gastric disease. The aim of this study was to describe the sonographic evaluation and macroscopic pathological findings of the stomach of adult horses intended for commercial slaughter. To this 39 intended for commercial slaughter horses were evaluated. Sonographic evaluation before slaughter transabdominal via the left side of abdomen for evaluation of the stomach was performed. After the slaughter of these animals their stomachs were collected, evaluated and photographed. The study concluded that ultrasonography identified the stomach in all animals evaluated, but did not allow a careful evaluation of the entire length of the viscera, especially the aglandular region and pleated border. All animals evaluated had injury to the gastric mucosa in different degrees. In animals evaluated, the stomach region was most affected by injuries glandular region, although the most severe lesions have been found in the ruffled border adjacent to aglandular region.

2014-01-01

A peptic ulcer, stomach ulcer, or gastric ulcer, also known as peptic ulcer disease (PUD), is a very common chronic disorder of the stomach which is mainly caused by damage or impairment of the stomach lining. Various factors such as pepsin, gastric acid, H. pylori, NSAIDs, prostaglandins, mucus, bicarbonate, and blood flow to mucosa play an important role in causing peptic ulcers. In this review article, our main focus is on some important gastroretentive drug delivery systems (GRDDS) (floating, bioadhesive, high density, swellable, raft forming, superporous hydrogel, and magnetic systems) which will be helpful in gastroretention of different dosage forms for treatment of peptic ulcer. GRDDS provides a mean for controlled release of compounds that are absorbed by active transport in the upper intestine. It also enables controlled delivery for paracellularly absorbed drugs without a decrease in bioavailability. The above approaches are specific for targeting and leading to a marked improvement in the quality of life for a large number of patients. In the future, it is expected that they will become of growing significance, finally leading to improved efficiencies of various types of pharmacotherapies.

Decompensated cicatrices stricture of upper alimentary canal is a complex disease clinically presenting a high mechanical blocking and leads to expressed abnormality of homeostasis, which requires its pathogenetic correction of urgency evidence. The greatest difficulty is correct protein-energy malnutrition and water-electrolyte metabolism. Prior to the imposition of stoma for feeding should begin immediately with standard parenteral nutrition solutions. In a subsequent it is nessesary to resort more physiologecal tube alimentasion. As with esophageal postambustion stricture electrical activity of the stomach inhibiting and in essentially remains small bowel function, preference should be given to ways of enteral threpsology support. This can be used as a balanced composition in breeding (primary breeding should be 1: 2) and special blends for intraintestinal alimentation (close chyme on line carrying the major components). In the case of postambustion struck of outlet termination stomach department when identified violations of the underlying functions of the digestive canal division, rational come to gentle tactics of enteral alimentation using mixtures, completely similar in composition to himus. At stricture janitor ulcer genesis appropriate tactics is enteral correction, similar to that used in the event of postambustion strictures of the zones when bowel function is largely preserved.

Mucosal injury and γ-irradiation produce persistent gastric ulcers in the rabbit. Evaluation of antiulcer drug binding to experimental ulcer sites

Yokel, R.A.; Dickey, K.M.

1991-01-01

A method producing persistent gastric ulcers in the rhesus monkey by combined mucosal injury and γ-irradiation was modified and evaluated in the rabbit. γ-Irradiation (800-1000 cGy) immediately after removal of 2-mm-diameter sections of antral mucosa resulted in ulcer craters 5-7 days later. Ulcer sites were characterized by loss of the mucosa, muscularis mucosa, and much of the submucosa. The exposed submucosa was coated with fibrin and necrotic debris infiltrated with heterophils, the rabbit equivalent of neutrophils. These ulcers strongly resemble human chronic gastric ulcers. Binding of Carafate (sucralfate; Marion Laboratories, Inc., Kansas City, MO) and Maalox (magnesia-alumina oral suspension; Wm. H. Rorer, Inc., Ft. Washington, PA) to ulcer and nearby nonulcer sites in the antrum was assessed 1 hour after drug dosing. Drug binding was determined by aluminum quantitation of stomach wall punch biopsies at necropsy. Both drugs significantly increased aluminum bound to the stomach wall compared with vehicle treatment. Significantly more antiulcer drug was bound to ulcer sites than to nearby nonulcer sites only after sucralfate administration. This model of persistent gastric ulcer should be useful to further study gastric ulcer pathogenesis and treatment

In a basic study of intraoperative radiation on the stomach, adult dogs were laparotomized, and radiated on the stomach and gastroduodenal anastomosed part with an electron beam to 1,000 - 4,000 rads to observed its effects on hematologic and histologic findings. 1) No leukopenia occurred with the radiation, but secondary effects such as anemia and hypoproteinemia were noted. 2) On the gastric wall, the mucosa was most severely effected by the radiation, presenting such changes as erosion, atrophy, disappearance of glandular tissue, and fibrosis with the lapse of time. 3) The radiation on the stomach to 3,000 rads was followed by ulceration in one month, by the start of repair of the ulceration in three months, and by its healing in eight months. Histologic examination disclosed no evident damages to the blood vessels by the radiation. 4) Delayed healing of the anastomosed part was noted as an effect of the radiation on this part. 5) The findings in this experiment appear to suggest that the single tolerable dose of electron beam radiation on the stomach and the gastroduodenal anastomosed part should be 3,000 rads.

We wanted to determine the multidetector computed tomography (MDCT) findings for differentiating benign ulcers from malignant ones. 18 clinicopathologically proven benign ulcers that had been detected by both endoscopy and MDCT were the focus of this study. 26 ulcerative advanced gastric cancers and 26 early gastric cancers with ulceration, all of which had been surgically proven, were selected as a control group. Five of the 26 early gastric cancers that were confined to the mucosa and that were not detected on CT were excluded in this study. The following CT findings were reviewed by two radiologists; ulcer size, the degree of enhancement and the thickness of inner enhancing layer in the ulcer base, the total thickness and the enhancing inner layer thickness in the largest part of the thickened ulcer mound, the presence of ulcer that projected beyond the healthy lumen, and the presence of perigastric fat infiltration and perigastric lymphadenopathy. An indiscernible thin-walled ulcer base (less than 1.5 mm) and suboptimal enhancement of the ulcer base for the discrimination of benign gastric ulcers from the malignant gastric ulcers showed sensitivities of 100% (18/18) and 78% (14/18), respectively, with specificities of 98% (46/47) and 92% (43/47), respectively. Ulcer projection was more significantly present in benign ulcer (13/18, 72%) than in the malignant gastric ulcers (7/47, 15%). The enhancing inner layer thickness in the ulcer mound was significantly greater in the AGC (mean; 7.4 mm) than in the benign gastric ulcers (mean, 2.2 mm). There were insignificant differences for ulcer size, total thickness of the ulcer mound, the perigastric fat infiltration and perigastric lymphadenopathy between the benign and malignant gastric ulcers. MDCT is an additional helpful diagnostic tool when benign gastric ulcers are histologically difficult to distinguish from malignant gastric ones.

We wanted to determine the multidetector computed tomography (MDCT) findings for differentiating benign ulcers from malignant ones. 18 clinicopathologically proven benign ulcers that had been detected by both endoscopy and MDCT were the focus of this study. 26 ulcerative advanced gastric cancers and 26 early gastric cancers with ulceration, all of which had been surgically proven, were selected as a control group. Five of the 26 early gastric cancers that were confined to the mucosa and that were not detected on CT were excluded in this study. The following CT findings were reviewed by two radiologists; ulcer size, the degree of enhancement and the thickness of inner enhancing layer in the ulcer base, the total thickness and the enhancing inner layer thickness in the largest part of the thickened ulcer mound, the presence of ulcer that projected beyond the healthy lumen, and the presence of perigastric fat infiltration and perigastric lymphadenopathy. An indiscernible thin-walled ulcer base (less than 1.5 mm) and suboptimal enhancement of the ulcer base for the discrimination of benign gastric ulcers from the malignant gastric ulcers showed sensitivities of 100% (18/18) and 78% (14/18), respectively, with specificities of 98% (46/47) and 92% (43/47), respectively. Ulcer projection was more significantly present in benign ulcer (13/18, 72%) than in the malignant gastric ulcers (7/47, 15%). The enhancing inner layer thickness in the ulcer mound was significantly greater in the AGC (mean; 7.4 mm) than in the benign gastric ulcers (mean, 2.2 mm). There were insignificant differences for ulcer size, total thickness of the ulcer mound, the perigastric fat infiltration and perigastric lymphadenopathy between the benign and malignant gastric ulcers. MDCT is an additional helpful diagnostic tool when benign gastric ulcers are histologically difficult to distinguish from malignant gastric ones

Full Text Available An 82-year-old man presented with upper gastrointestinal bleeding. A polypoid lesion of the distal stomach with focal ulceration was seen at endoscopy. This was treated by a partial gastrectomy. The resected stomach contained two separate tumours near the pylorus: a gastrointestinal stromal tumour (GIST and an adjacent lipoma. The literature includes case reports of synchronously occurring GIST and adenocarcinoma, GIST and mucosa-associated lymphoid tissue lymphoma and GIST and carcinoid tumour. Herein is the first case report of two distinct mesenchymal tumors coexisting in the stomach.

Full Text Available Abstract Background Metastatic tumours of the stomach present a clinical dilemma for the surgeon. Palliative surgical resection can alleviate symptoms and prolong survival in selected patients. However, previous studies have used open methods of surgical resection with potentially high morbidity and mortality. We describe the use of laparoscopic wedge resection of the stomach for palliative resection of metastatic melanoma to highlight the benefits of this technique. Case presentation A 58 year old male was investigated for iron deficiency anaemia while under treatment for pulmonary metastatic malignant melanoma. An upper gastrointestinal endoscopy revealed a 5 cm diameter ulcer on the anterior wall of the stomach, biopsies from the ulcer confirmed metastatic melanoma. Laparoscopic wedge resection of the stomach lesion was performed without complication. Conclusion Laparoscopic approach has many benefits and is useful for the palliative resection of rare tumours of the stomach in order to preserve the quality of life. Its use should be considered in selected patients.

　Most gastric bezoars can be treated with endoscopic fragmentation combined with or without cola dissolution, whereas laparotomy or laparoscopic surgery is generally inevitable for small intestinal bezoars because they cause small bowel obstruction. Therefore, early diagnosis and management of gastric bezoars are necessary to prevent bezoar-induced ileus. To investigate the incidence of overlooked gastric bezoars during the initial esophagogastroduodenoscopy, we retrospectively reviewed the cases of 27 patients diagnosed with gastrointestinal bezoars. The bezoars were diagnosed using esophagogastroduodenoscopy (n=25), abdominal ultrasonography (n=1), and barium follow-through examination (n=1). Bezoars were overlooked in 9/25 patients (36.0%) during the initial endoscopy examination because the bezoars were covered with debris in the stomach. Of the 9 patients, 8 had concomitant gastric ulcers, and the other patient had gastric lymphoma. Although a computed tomography (CT) scan was performed before the second-look endoscopy in 8 of the 9 patients, the bezoars were mistaken as food debris on CT findings and were overlooked in these patients. In conclusion, gastric bezoars may not be discovered during the initial esophagogastroduodenoscopy and CT scan. In cases with debris in the stomach, second-look endoscopy is essential to detect bezoars.

Symptoms of epigastric pain raise the possibility of peptic ulcer disease and lead to an examination of the stomach and duodenum. Hematemesis or melena is also a strong indication. The nausea-vomiting complex on a subacute or chronic basis raises the possibility of an obstructive lesion. A palpable mass in the upper abdomen may involve the stomach. Weight loss and anorexia are less specific symptoms but can occur with gastric cancer. Major changes in indications have occurred now that ultrasonography, computed tomography (CT), and magnetic resonance (MR) imaging are available. No longer is the gut studied to detect extra-gut disease. Currently, the duodenal contour is not important in the search for pancreatic disease. All intra-abdominal structures can now be seen directly using CT or ultrasound

Endoscopic submucosal dissection (ESD) can remove early stage GI tumors of various sizes en bloc; however, success requires reducing the relatively high postprocedure bleeding rate. The aim of this study was to assess the safety and efficacy of a novel, fully synthetic, and self-assembled peptide solution that functions as an extracellular matrix scaffold material to facilitate reconstruction of normal tissues in ESD-induced ulcers. Consecutive patients who underwent gastric ESD were prospectively enrolled. Immediately after the resection, the solution was applied to the site with a catheter. Gastric ulcers were evaluated by endoscopy and classified as active, healing, or scarring stages at weeks 1, 4, and 8 after ESD. Forty-seven patients with 53 lesions, including 14 (29.8%) previously on antithrombotic therapy and 2 (4.3%) requiring heparin bridge therapy, were analyzed; 2 patients were excluded, 1 with perforations and 1 with persistent coagulopathy. The mean size of the en bloc resected specimens was 36.5 ± 11.3 mm. The rate of post-ESD bleeding was 2.0% (1/51; 95% CI, 0.03-10.3). Transitional rate to the healing stage of ESD-induced ulcers at week 1 was 96% (49/51). Subsequent endoscopies demonstrated the scarring stage in 19% (9/48) and 98% (41/42) at weeks 4 and 8, respectively. No adverse effects related to this solution occurred. The use of this novel peptide solution may potentially aid in reducing the delayed bleeding rate by promoting mucosal regeneration and speed of ulcer healing after large endoscopic resections in the stomach. Further studies, particularly randomized controlled studies, are needed to fully evaluate its efficacy. ( 000011548.). Copyright © 2016 American Society for Gastrointestinal Endoscopy.

The purpose of our study was to find out the significant findings of stomach on FDG PET. Thirty-nine patients who underwent both FDG PET and endoscopy from Jun. 2003, to Aug. 2004 were included in our study. In all of them, FDG PET and gastrofibroscopy were performed within one week. One man who had undergone subtotal gastrectomy was excluded. We reviewed 38 cases (18 for medical check up, 15 for work up of other malignancies, and 5 for the evaluation of stomach lesion). Their mean age was 56 years old (range:32{approx}79), men and women were 28 and 10, respectively. On interpretation of FDG PET scan, two nuclear physician evaluated five parameters on FDG-PET findings of stomach with a concensus : 1) visual grades 2) maximum SUV (SUVmax), 3) focality, 4) asymmetry, and 5) gross appearance. We correlated FDG PET findings of stomach with those of endoscopy. On endoscopy, six of 38 patients were proven as gastric cancer, and others had inflammatory lesion (ulcer in 3, chronic gastritis in 12, uncommon from gastritis in 5) or benign noninflammatory lesions (polyp and varix in 3, and normal limit). On the visual analysis, FDG uptake of stomach cancer had the tendency of higher uptake than the other lesions. SUVmax of gastric cancer was 7.95{+-}4.83 which was significantly higher than the other benign lesions (2.9{+-}0.69 in ulcer, 3.08{+-}1.2 in chronic gastritis 3.2{+-}1.49 in uncommon from gastritis). In the appearance of stomach on PET, gastric cancer was shown as focal lesion (5 of 6), and those of benign inflammatory lesions were asymmetric (14 of 20), and diffuse (9 of 20). Some cases of chronic inflammatory lesions, such as ulcer, and chronic gastritis, showed focal appearance and mimicked cancerous lesion (4 of 15). On FDG PET, the lesions of stomach cancer had higher FDG uptake and focal appearance comparing with the other benign inflammatory lesions. However, ulcer, and chronic gastritis showed focal appearance on PET, which could be mimicked as cancerous

Full Text Available Objective. To assess safety of nimesulid in rheumatic pts with history of ulcer or multiple erosions (ME of stomach and/or duodenal mucosa. Methods. 42 pts with rheumatic diseases aged 22-73 years were included. AH had gastric or duodenal ulcers or ME (n>10 connected with NSAID treatment and confirmed by endoscopy no more than 6 months before the beginning of the study. Pts were included after healing of ulcers and erosions. The pts were randomized to receive Nimesulid 200 mg/day (group 1 or Diclofenac suppositoria 100 mg/day + ranitidine 150 mg/day (group 2. Esophagogastroduodenoscopy was performed before and 12 weeks after the beginning of treatment. Results. Relapse of stomach ulcer was observed in I pts of group 1 (5,6%. Relapse of NSAID-induced ulcers and ME was noted in 6 pts of group 2 (33,3%: in 4 cases stomach ulcers, in 1 case stomach ME, in 1 case duodenal ulcer (p=0,0424. Presence of gastralgias and dyspepsia was noted in 36,8% pts of group 1 and in 20% pts of group 2 (p=0,0539. In 1 pts of group 2 gastralgias were the reason for premature endoscopy. Conclusion. Nimesil (Nimesulid can be considered as a more safe drug than classical NSAIDs with smaller risk of serious gastroduodenal complications development in rheumatic pts with ulcer history. The results of the study allow to recommend Nimesulid as a drug of choice for treatment of pts with history of NSAID-induced gastropathy.

Cibotium barometz is a medical herb used traditionally in the Malaysian peninsula for several ailments, including gastric ulcer. The aim of this study was assessment the anti-ulcer effects of C. barometz hair on ethanol-induced stomach hemorrhagic abrasions in animals. Seven groups of Sprague Dawley (SD) rats were administered 10% Tween 20 in the normal control and ulcer control groups, and omeprazole 20 mg/kg and 62.5, 125, 250, and 500 mg/kg of C. barometz hair extract in the experimental groups. After 60 min, the normal control group of rats was orally administered 10% Tween 20, while absolute ethanol was orally administered to the groups of ulcer control, omeprazole and experimental groups. Stomachs of the rats were examined macroscopically and histologically. Homogenates of stomachs were used to evaluate endogenous antioxidant enzyme activities. Rats pre-fed with plant extract presented a significant decrease in the sore area, increased pH of gastric contents and preserved stomach wall mucus compared to the ulcer group. Histologically, rats pre-fed with C. barometz hair extract showed mild to moderate disruptions of the surface epithelium while animals pre-fed with absolute ethanol showed severe disruptions of the stomach epithelium with edema and leucocyte penetration of the submucosal layer. A Periodic acid Schiff (PAS) staining revealed that each rat pre-treated with the plant extract displayed an intense uptake of stomach epithelial glycoprotein magenta color compared to the ulcer control group. Immunohistochemical analysis revealed that rats pre-fed with the plant extract showed an up-regulation of the heat shock protein 70 (HSP70) and down-regulation of Bax proteins compared to ulcer control rats. Homogenates of the stomach tissue demonstrated significant increases in the endogenous antioxidant enzymatic activity and decreased lipid peroxidation (MDA) in rats pre-treated with C. barometz hair extract compared with the ulcer control rats.

One thousand five hundred and eighty-three patients who were x-rayed for dyspepsia showed varioliform erosions in 15.3%. Men had an incidence of 9.8%, almost twice as common as in women (5.5%). Mucosal polyps, usually of the hyperplastic type, occurred in 2.4%. 15% of patients with gastric ulcers and 16% of patients with duodenal ulcers had varioliform erosions. On the other hand, amongst patients with erosions, 11% had gastric ulcers and 8.3% duodenal ulcers. The definitions of erosion which have been given in the literature are partly contradictory, and are discussed. Varioliform erosions, also known as complete erosions, may be acute or chronic. They are the third most common cause of bleeding from the upper gastrointestinal tract. With modern radiological methods of examining the stomach, they are no longer a rare finding. 5 figs.

Results of treatment of 1309 patients with perforated and bleeding pyloroduodenal ulcers for 20-years period have been analysed. Resection of the stomach performed in 85 cases resulted in high postoperative lethality which made up in bleeding ulcers 14.8%. Drainage operations of the stomach with excision or suturing of ulcer combined with bilateral truncal vagotomy was performed in 60 patients, postoperative lethality rate being 8.4%. 128 patients underwent selective proximal vagotomy together with pyloro- and duodenoplasty, lethality rate being 1.6%. Combined vagotomy (posterior truncal and anterior sero-muscular) with excision of ulcer, transversal pyloroplasty and duodenoplasty was carried out in 1036 patients (postoperative lethality--2.4%). Excellent and good functional results were achieved in 79.6% of the patients.

The results of radiology and endoscopy were compared in 140 patients who had undergone gastric surgery for ulcer disease. Of 74 patients who were examined with single-contrast radiography, 37 had abnormalities that were demonstrated endoscopically. The radiographic sensitivities in these patients were: gastritis 2/22 (9%); ulcer 3/5 (60%); obstruction 8/8 (100%); and miscellaneous abnormalities 2/2 (100%). The predictive accuracy of a diagnois of ulcer was 38%. Of the 66 patients who were examined with double-contrast radiography, 33 abnormalities were found with endoscopy. The radiographic sensitivities were: gastritis 3/13 (23%); ulcer 7/10 (70%); obstruction 4/4 (100%); and miscellaneous abnormalities 6/6 (100%). The predictive accuracy of a diagnosis of ulcer was 44%. Radiology appears to be unreliable in diagnosing gastritis and recurrent ulceration in the post-operation stomach. The double-contrast technique does not offer significant improvement over the single-contrast method in evaluating these postoperative problems

Equine gastric ulcer syndrome (EGUS) is an umbrella term used to describe ulcers in the nonglandular squamous and glandular mucosa, terminal esophagus, and proximal duodenum. Gastric ulcers in the squamous and glandular regions occur more often than esophageal or duodenal ulcers and likely have a different pathogenesis. At present, omeprazole is accepted globally as the best pharmacologic therapy for both regions of the stomach; however, the addition of coating agents and synthetic prostaglandins could add to its effectiveness in treatment of EGUS. Dietary and environmental management are necessary for prevention of recurrence. Copyright © 2016 Elsevier Inc. All rights reserved.

Improved radiological diagnosis in the stomach by means of an improved contrast material

Lotz, W.; Liebenow, S.

Our experience with a cheap contrast medium, which we prepare ourselves, is described, stretching over a period of 18 months. It is based on the bubbly barium first described by Op den Orth and is made by means of carbone dioxide in a soda water syphon. It is better for detailed contrast examination of the stomach than the commercially available contrast media. It is thought that this is due to optimal viscosity for wetting of the mucosa, optimal size of the barium sulphate particles, which are larger than one micron, and greater distension of the stomach due to greater quantities of CO 2 . The use of bubbly barium for routine examination of the stomach, using double contrast and hypotonia with graded compresseion, almost always results in demonstration of the areae gastricae in large parts of the stomach. We regard this as a sign of a good examination, since we are then able to demonstrate small lesions such as complete or incomplete erosions, ulcer scars of flat ulcers. (orig.) [de

Famotidine was labeled with iodine-125 to obtain {sup 125}I-famotidine ({sup 125}I-fam) as an agent for ulcer imaging. The radiochemical yield of {sup 125}I-famotidine reached approximately 98.5 ± 0.23% at optimum conditions of pH, oxidizing agent, reaction time and the amount of substrate. {sup 125}I-fam was stable for 48 h. Different chromatographic techniques were used to determine the radiochemical yield and purity. Intravenous biodistribution studies of {sup 125}I-fam revealed high concentration in the stomach ulcer, reaching about 65.9 ± 0.28% of the total injected dose at 30 min post injection. This concentration of {sup 125}I-fam in stomach ulcer makes this agent promising for stomach ulcer imaging.

We investigated the effect of Vitamin C (Vit C) on the changes of activity of the enzymes of NO-synthase system, nitric oxide content, lipoperoxidation processes, activity of SOD and catalase in gastric mucosa (GM), and concentrations of L-arginine, Vit C and Vit E in the blood of rats under conditions of experimental ulcer of the stomach caused by adrenaline injection. Vit C displayed a pronounced antioxidant action, reduced the degree of destructive affections, diminished the activity of iNOS and lipoperoxidation processes, decreased the NO content and SOD activity. Furthermore, the concentration of L-arginine and Vit C in the blood was increased. Combined action of Vit C with L-arginine reduced the degree of GM lesions, activity of eNOS and the content of NO in GM whereas the concentration of L-arginine in blood was increased. Under conditions of Vit C action and iNOS and COX-2 blockage, the activity of NO-synthases and lipoperoxidation processes were slightly decreased, indicating on dominant action of Vit C.

The first-ever case of a 54-year-old woman who overdosed on non-steroidal anti-inflammatory drugs in an attempt at suicide. Before that incident, she had not been treated for coexisting diseases such as rheumatoid arthritis or depression. At the time of admission to the General Surgery Department, the patient reported pains in the epigastric region with accompanying nausea and vomiting with mucous content as well as the inability to ingest food orally. Despite parenteral and enteral feeding, the patient exhibited a drop in body mass. The histopathologic examination of a sample taken from the stomach during gastroscopy showed some non-specific necrotic and inflammatory masses with granulation. Intraoperatively, a very small, infiltrated stomach with an initial section of duodenum was identified. A total stomach resection together with the reconstruction of digestive tract continuity was performed using the Roux-Y method. Histopathologic examination of the stomach revealed a deep, chronic and exacerbated inflammatory condition with an extensive ulceration over the entire length of the stomach, reaching up to the pylorus. Additionally, numerous lymphatic glands with inflammatory reaction changes were observed.

1984-01-01

The purpose of this study was to evaluate three radiolabels for the drug Carafate (basic aluminum sucrose octasulfate), which, when ingested orally, is believed to coat gastric ulcers and protect them from digestive enzymes to promote healing. In order to study the mode of action and residence time in the stomach using external imaging, a gamma-emitting label which is truly bound to the molecule is needed. Carafate has been radiolabeled with Se-75, In-111 (both chemically incorporated into the molecule) and with Tc-99m-HSA which physically adheres to Carafate. In the presence of stomach acid, Carafate polymerizes; when the labeled Carafates were mixed in vitro with 0.1N HCl, >90% of the radio-activity was associated with the polymer in the case of Se-75 and Tc-99m, but the In-111 label was less stable (25-35% bound to polymer). The three labeled preparations were administered orally to rats with gastric ulcers, and the transit of each was followed by gamma camera imaging. Gamma camera images confirmed radioactivity remaining at the ulcer site after unbound material had emptied from the stomach, and the focal activity persisted for >5 hours. The stomachs were then removed, washed and dissected at 5.5 hours and in vitro measurements of ulcer crater: normal stomach tissue radioactivity ratios averaged 15.4, 6.3, and 5.6 for the Se-75, In-111, and Tc-99m-HSA labels, respectively. Biodistribution studies of oral Se-75-Carafate in rats and pigs indicated that very little is absorbed from the GI tract and the distribution is similar to that of C-14-Carafate. It is concluded that Se-75 is the best marker for Carafate of these three gamma-emitting labels and Se-75-Carafate is suitable for studying the kinetics of the drug Carafate in human subjects

Hepatoid adenocarcinoma of the stomach is a gastric carcinoma with both adenocarcinomatous and hepatocellular carcinomatous differentiation. It usually produces large amount of serum alpha-fetoprotein. It often occurs in aged person, commonly located in the gastric antrum. Because of early lymph node and liver metastasis, prognosis is poor. A case of hepatoid adenocarcinoma of the stomach in a 49-year-old man is reported. The patient's serum alpha-fetoprotein level was high (3380 ng/ml). Liver function test was normal, otherwise. A mass was observed in right lobe of the liver on US and CT. It was hypervascular with increased uptake of lipiodol on hepatic arteriography. A large ulcerative tumor involving the gastric antrum and body was also found at barium study of the stomach. Subtotal gastrectomy nad right lobectomy of the liver resulted in rapid decrease in serum alpha-fetoprotein. Histopathologically the diagnosis was hepatoid adenocarcinoma of the stomach with liver metastasis.

2016-09-01

Full Text Available Background & Aims: During aging, physiological changes in the stomach result in more tenuous gastric tissue that is less capable of repairing injury, leading to increased susceptibility to chronic ulceration. Spasmolytic polypeptide/trefoil factor 2–expressing metaplasia (SPEM is known to emerge after parietal cell loss and during Helicobacter pylori infection, however, its role in gastric ulcer repair is unknown. Therefore, we sought to investigate if SPEM plays a role in epithelial regeneration. Methods: Acetic acid ulcers were induced in young (2–3 mo and aged (18–24 mo C57BL/6 mice to determine the quality of ulcer repair with advancing age. Yellow chameleon 3.0 mice were used to generate yellow fluorescent protein–expressing organoids for transplantation. Yellow fluorescent protein–positive gastric organoids were transplanted into the submucosa and lumen of the stomach immediately after ulcer induction. Gastric tissue was collected and analyzed to determine the engraftment of organoid-derived cells within the regenerating epithelium. Results: Wound healing in young mice coincided with the emergence of SPEM within the ulcerated region, a response that was absent in the aged stomach. Although aged mice showed less metaplasia surrounding the ulcerated tissue, organoid-transplanted aged mice showed regenerated gastric glands containing organoid-derived cells. Organoid transplantation in the aged mice led to the emergence of SPEM and gastric regeneration. Conclusions: These data show the development of SPEM during gastric repair in response to injury that is absent in the aged stomach. In addition, gastric organoids in an injury/transplantation mouse model promoted gastric regeneration. Keywords: Epithelial Regeneration, Gastric Cancer, Human Gastric Organoids, CD44v

Cholecystography with 99m Tc-EHIDA was performed to assess the preprandial empty function of gallbladder and then solid meal labelled with 99m Tc-DTPA was given to assess the postprandial empty function of stomach in 25 patients with NUD. The examinations were repeated in 15 patients with hypomotilitic stomach and gallbladder following administration of Domperidone 20 mg t.i.d for four weeks. The results showed that the empty function of stomach was closely related to the amplitude and frequency of antrum contractile peristaltic waves, all NUD patients who had delayed gastric empty also had hypomotilitic gallbladder. This may be one of the pathophysiologic bases of NUD. The movements of stomach and gallbladder both preprandial and postprandial were synchronous. Domperidone can restore hypomotility of stomach and gallbladder in NUD patients to normal, and the movements of stomach and gallbladder still remained synchronous

Gastrointestinal mesenchymal tumors are a group of tumors, which originate from the mesenchymal stem cells of the gastrointestinal tract. Gastric schwannoma is a very rare gastrointestinal mesenchymal tumor, which represents only 0.2% of all gastric tumors and 4% of all benign gastric neoplasms. We report a 55 years old lady who suffered from pain epigastrium, vomiting, occasionally with blood, loss of appetite and weight loss. Endoscopic examination showed a round submucosal tumor with a central ulceration along the greater curvature of the stomach. The pathological examination revealed a picture of spindle cell tumor. Immunohistochemical stain was strongly positive for S-100 protein stain, and non-reactive for CD34, CD117, consistent with benign nerve sheath tumor of stomach i.e. gastric schwannoma. (author)

Ganoderma lucidum Pharmacopuncture for the Treatment of Acute Gastric Ulcers in Rats

2014-09-01

Full Text Available Objectives: The gastric ulcer is a common disorder of the stomach and duodenum. The basic physiopathology of a gastric ulcer results from an imbalance between some endogenous aggressive and cytoprotective factors. This study examined whether Ganoderma lucidum pharmacopuncture (GLP would provide protection against acute gastric ulcers in rats. Methods: Sprague-Dawley rats were divided randomly into 4 groups of 8 rats each: normal, control, normal saline (NP and GLP groups. The experimental acute gastric ulcer was induced by using an EtOH/HCl solution and the normal group received the same amount of normal saline instead of ethanol. The NP and the GLP groups were treated once with injections of saline and GLP, respectively. Two local acupoints were used: CV12 (中脘 which is the alarm point of the Stomach Meridian, and ST36 (足三里, which is the sea point of the Stomach Meridian. The stomachs from the rats in each group were collected and analyzed for gross appearance and histology. Also, immunohistochemistry staining for BAX, Bcl-2 and TGF-β1 was performed. Results: Histological observations of the gastric lesions in the control group showed comparatively extensive damage of the gastric mucosa and necrotic lesions had penetrated deeply into the mucosa. The lesions were long, hemorrhagic, and confined to the glandular portions. The lesions were measured microscopically by using the clear depth of penetration into the gastric mucosal surface. The length and the width of the ulcer were measured and the inhibition percentage was calculated. Wound healing of the acute gastric ulcer was promoted by using GLP, and significant alterations of indices in gastric mucosa were observed. Such protection was shown by gross appearance, histology and immunohistochemistry staining for BAX, Bcl-2 and TGF-β1. Conclusion: These results suggest that GLP administered at CV12 and ST36 can provide significant protection to the gastric mucosa against an ethanol

In the following article, we will discuss general issues relating to acute and late gastric's radiation toxicities. The tolerance of the stomach to complete or partial organ irradiation is more un-appreciated than for most other organs. We consulted the Medline database via PubMed and used the key words gastric - radiotherapy - toxicity. Currently, 60 Gy or less is prescribed in gastric radiation therapy. Acute clinical toxicity symptoms are predominantly nausea and vomiting. Although there is a general agreement that the whole stomach tolerance is for doses of 40 to 45 Gy without unacceptable complication, it is well established that a stomach dose of 35 Gy increases the risk of ulcer complications.

An x-ray picture of motor-evacuatory stomach function was studied in patients with pyloroduodenal ulcers after SPV with and without drainage (435 patients aged 16 to 80). Methods of investigation included polyprojectional radioscopy and panoramic and spot films at various time intervals after barium suspension intake. Stomach investigation was performed before operation as well as 2-3 weeks, 3-6 mos, 1-2 yrs, 3-5 yrs, and 7-10 yrs after it. Motor-evacuatory stomach function was studied over time. The least changes in motor-evacuatory fucntion were observed after SPV without drainage as a result of preserving pyloric contractility

In a basic study of intraoperative radiation on the stomach, adult dogs were laparotomized, and radiated on the stomach and gastroduodenal anastomosed part with an electron beam to 1,000 to 4,000 rads to observe its effects on hematologic and histologic findings. 1) No leukopenia occurred with the radiation, but secondary effects such as anemia and hypoproteinemia were noted. 2) On the gastric wall, the mucosa was most severely effected by the radiation, presenting such changes as erosion, atrophy, disappearance of glandular tissue, and fibrosis with the lapse of time. 3) The radiation on the stomach to 3,000 rads was followed by ulceration in one month, by the start of repair of the ulceration in three months, and by its healing in eight months. Histologic examination disclosed no evident damages to the blood vessels by the radiation. 4) Delayed healing of the anastomosed part was noted as an effect of the radiation on this part. 5) The findings in this experiment appear to suggest that the single tolerable dose of electron beam radiation on the stomach and the gastroduodenal anastomosed part should be 3,000 rads.

Sarcomatoid carcinoma is a rare neoplasm of epithelial origin but consists partly of variable differentiated tumor cells of mesenchymal origin. Accurate diagnosis, including differentiation from adenocarcinoma or gastrointestinal stromal tumor, is difficult. We experienced three cases of sarcomatoid carcinoma of the stomach, and describe the radiological and pathologic findings. One case involved a polypoid mass in the antrum, another a mass with a large ulcer mimicking a Bormann type-II adenocarcinoma in the body, while in the third case, an intraluminal bulky mass arising from the cardia of the stomach was present. This was not differentiated from cancer or stromal tumor. (author)

Gastric ulcer localization: Potential use of in vivo labeling

A previous work suggests that sucralfate labeled by binding to Tc-99m HSA permits the visualization of gastric ulcers. Potential problems with this technique are: 1) decreased binding of sucralfate to ulcer sites due to the labeling method of binding to exogenous protein (HSA); 2) overlying activity that may obscure identification of the ulcer. Because of these problems we have examined the possibility of direct in vivo Tc-99m labeling of sucralfate after it has already bound to the ulcer. In vitro studies were done to determine the binding of Tc-99m pertechnetate to sucralfate in the presence of tin in HCl solution at pHs comparable to those found in the stomach. Rapid and efficient labeling was achieved with 75-95% of the label bound to sucralfate at 30 minutes. In vivo studies were performed in rabbits with aspirin induced ulcers and in ulcer free human volunteers. The animal studies confirm that orally administered Tc-99m pertechnetate will bind to previously ingested sucralfate and that the labeled material will bind to the ulcers. Tc-99m pertechnetate was also shown to bind well to previously ingested sucralfate in humans. The results suggest that it is possible to label sucralfate in vivo. This method would offer the following advantages: 1) a simpler labeling procedure; 2) the potential of increased sensitivity by delaying the labeling until much of the sucralfate not bound to ulcer has passed, and thus decreasing the activity that remains in the stomach; and also by leaving the protein binding sites of the sucralfate free to interact with the ulcer since no exogenous protein is involved in labeling

The aim of the study was to examine whether endogenous cortisol and adrenalin have a role in the formation of stress ulcers in intact and adrenalectomized rats. The study was composed of 4 experiments: ulcerated areas in stomachs of adrenalectomized and intact rats were measured, adrenaline (100 μg/kg) and prednisolone (5 mg/kg) were injected intraperitoneally in adrenalectomized rats, metyrapone (200 mg/kg) and metyrosine (200 mg/kg) were administered to intact rats, and metyrapone (200 mg/kg) and metyrosine (200 mg/kg) were administered orally with yohimbine (10 mg/kg) and yohimbine (10 mg/kg) alone were administered to intact rats. After 24-hour restraint stress, ulcerated areas were measured. In the stomach of intact rats, the degree of stress ulcer was 7.25 times more severe than that noted in adrenalectomized rats. Furthermore, stress ulcers in adrenalectomized rats that received adrenaline or prednisolone only were fewer and less severe than rats receiving both adrenaline and prednisolone. Simultaneous administration of adrenaline and prednisolone did not prevent the formation of stress ulcers. However, either of these hormones alone (adrenaline or prednisolone), in the absence of the other, repressed the formation of stress ulcers. This antiulcer activity may be related to α2-adrenergic receptor activity. Copyright © 2010 Elsevier Inc. All rights reserved.

Gastrointestinal toxicity of nonsteroidal antiinflammatory drugs includes perforations and bleeds. Several preventive strategies are being tested for cost-effectiveness, but little is known about the costs of the complications they are trying to prevent. We estimated the direct costs of hospital treatment of bleeding and perforated ulcers in a university hospital, from data in discharge letters and the hospital management information system. Eligible patients had been treated in the VU University Medical Center between January 1997 and August 2000 for an ulcer bleed or perforation (International Classification of Diseases code 531-4). Resource use comprised hospitalization days and diagnostic and therapeutic interventions. Insurance claim prices determined the costs from the payers' perspective. In a secondary analysis we excluded resource use that was clearly related to the treatment of comorbid illness. Fifty-three patients with a bleeding (n = 35) or perforated ulcer (n = 15) or both (n = 3) were studied, including 14 with comorbidity; 22 complications occurred in the stomach, 29 in the duodenum, one in both stomach and duodenum, and one after partial gastrectomy. A simultaneous bleed and perforation was most expensive (26,000 euro), followed by perforation (19,000 euro) and bleeding (12,000 euro). A bleed in the duodenum was more expensive than in the stomach (13,000 euro vs 10,000 euro), while the opposite was seen for perforations (13,000 euro vs 21,000 euro). Comorbidity increased costs substantially: even after correction for procedures unrelated to the ulcer complication, comorbidity more than doubled the costs of treatment. Treatment of complicated ulcers is expensive, especially in patients with comorbid conditions.

There are strong beliefs in the efficacy of traditional medical systems worldwide. Many herbs have been acclaimed to possess antiulcer effects and could be unexplored sources of new lead compounds. Sida corymbosa R. E. Fries (Malvaceae) is used in Northern Nigeria to treat ulcers and wounds. This work aimed to investigate the usefulness of Sida corymbosa in treatments of stomach ulcers and wounds in traditional medicine. Effect of the aqueous extract was determined on gastric ulceration, rate of wound healing and inflammation using ethanol-induced and diclofenac-induced ulceration, wound excision model and albumin-induced inflammation respectively in rats. The study demonstrated the anti-ulcer activity of Sida corymbosa as the extract (250, 500 and 1000 mg/kg) showed a dose-dependent, significant (PSida corymbosa on surgically created incisions produced an increase in the rate of healing of the wounds. The extract of Sida corymbosa exhibited a significant (P Sida corymbosa has constituents with the ability to reduce the severity of haemorrhagic gastric lesions, promote wound healing and reduce inflammation. These actions may be attributed to any one of the active constituents or as a result of synergistic effects of these phytoconstituents. This study validates the use of the plant in traditional medicine for the treatment of stomach ulcers and wounds.

The paper is based on the analysis of clinical, X-ray, and morphological studies in 74 patients with massive gastrointestinal hemorrhage. The paper presents the specific features of X-ray studies of patients with bleeding gastroduodenal ulcers. X-ray studies shout be twice performed in these patients. The first study is conducted if gastroscopic findings are unclear, the repeated one is carried out while assessing changes in disease regression. X-ray diagnosis of bleeding ulcers is determined by their sites and the nature of an ulcerous process. The X-ray diagnosis of chronic callous gastric ulcers accompanied by hemorrhage was based on the detection of two direct symptoms of a niche on the gastric outlines and configuration and an inflammatory mound on the gastric outline and configuration. That of chronic bleeding ulcers of the duodenal bulb is based not only on searches niche, but other signs of the disease - the deformed organ, and the magnitude of a periprocess. 10 refs., 5 figs

Gastric emptying abnormal in duodenal ulcer

To investigate the possibility that an abnormality of gastric emptying exists in duodenal ulcer and to determine if such an abnormality persists after ulcer healing, scintigraphic gastric emptying measurements were undertaken in 16 duodenal ulcer patients before, during, and after therapy with cimetidine; in 12 patients with pernicious anemia, and in 12 control subjects. No difference was detected in the rate or pattern of gastric emptying in duodenal ulcer patients before and after ulcer healing with cimetidine compared with controls, but emptying of the solid component of the test meal was more rapid during treatment with the drug. Comparison of emptying patterns obtained in duodenal ulcer subjects during and after cimetidine treatment with those obtained in pernicious anemia patients and controls revealed a similar relationship that was characterized by a tendency for reduction in the normal differentiation between the emptying of solid and liquid from the stomach. The similarity in emptying patterns in these groups of subjects suggests that gastric emptying of solids may be influenced by changes in the volume of gastric secretion. The failure to detect an abnormality of gastric emptying in duodenal ulcer subjects before and after ulcer healing calls into question the widespread belief that abnormally rapid gastric emptying is a feature with pathogenetic significance in duodenal ulcer disease.

Gastroduodenal ulceration in foals.

Becht, J L; Byars, T D

1986-07-01

Gastroduodenal ulceration is becoming recognised as an important disease in foals during the first few months of life. Aetiopathogenesis is presumed to be similar to peptic disease in humans associated with back diffusion of hydrogen ions into the mucosa. Many factors have been incriminated as predisposing foals to ulceration but few have been proven. To date, use of non-steroidal anti-inflammatory agents has been the only documented cause of gastroduodenal ulceration in foals. The clustering of affected foals on certain farms suggests an infectious aetiology but attempts to identify a causative organism have been unsuccessful. Four clinical syndromes defined for foals with gastroduodenal ulceration include: silent ulcers, which occur most often in the non-glandular stomach along the margo plicatus and are identified as incidental findings at necropsy; active ulcers which are often manifested by abdominal pain, excessive salivation and bruxism; perforating ulcers which usually result in a severe, diffuse peritonitis; and pyloric or duodenal obstruction from a healing ulcer. General approaches to therapy of a foal with active ulceration consist of reduction of gastric acidity and enhancement of mucosal protection. Antacids and type 2 histamine receptor antagonists are used most often to neutralise or decrease acid secretion, respectively. Sucralfate, a locally active sulphated sucrose preparation, is commonly used as a cytoprotective agent. The efficacy and safety of many products used have not been evaluated adequately in foals. Perforating ulcers are usually associated with death or humane destruction of the foal because of fulminating peritonitis. Surgical intervention and bypass procedures are indicated in foals that develop pyloric or duodenal obstructions from healing ulcers.

Thirty-eight patients who underwent both FDG PET and endoscopy within one week from Jun. 2003, to Aug. 2004 were included in this study. We reviewed 38 patients (18 for medical check up, 15 for work up of other malignancies, and 5 for the evaluation of stomach lesion). Their mean age was 56 years old (range:32 {approx} 79), men and women were 28 and 10, respectively. Two nuclear physicians evaluated five parameters on FDG PET findings of stomach with a consensus: 1) visual grades 2) maximum SUV (max.SUV) 3) focal 4) diffuse and 5) asymmetric patterns. We correlated the lesions of FDG PET findings of stomach with those of endoscopy. We considered more than equivocal findings on FDG PET as positive. The six of 38 patients were proven as malignant lesions by endoscopic biopsy and others were inflammatory lesions (ulcer in 3, chronic atrophic gastritis in 12, uncommon forms of gastritis in 5), non-inflammatory lesions (n=3), and normal stomach (n=9). By the visual analysis, malignant lesions had higher FDG uptake than the others. The max.SUV of malignant lesions was 7.95 {+-} 4.83 which was significantly higher than the other benign lesions (2.9 {+-} 0.69 in ulcer, 3.08 {+-} 1.2 in chronic atrophic gastritis, 3.2 {+-} 1.49 in uncommon forms of gastritis ( {rho} =0.044). In the appearance of stomach on FDG PET, malignant lesions were shown focal (5 of 6) and benign inflammatory lesions were shown diffuse (9 of 20) and asymmetric (14 of 20). Benign lesions and normal stomach were shown variable degrees of uptake and patterns. Some cases of benign inflammatory lesions such as ulcer and gastritis were shown focal and mimicked cancerous lesions (4 of 15). Gastric malignant lesions had higher FDG uptake and focal pattern

Twelve horses with clinical symptoms of a gastric disorder were studied by gastroscopy. Symptoms of gastric disorders were periprandial colic, bruxism, ructus and reflux. Preliminary to gastroscopy the horses were fasted for 24 h. Access to water was not restricted. The gastroscopy could be conducted easily using a fiberscope 2.5 m in length and 11 mm in outer diameter. While ulcers were present in the squamous fundus of all horses only one horse showed ulceration of the glandular fundus. Solitary ulcers near the margo plicatus were found in horses with mild clinical symptoms. In contrast, diffuse gastroesophageal ulceration was accompanied by severe clinical symptoms. Four horses were affected by an acute gastroesophageal ulceration with gastric reflux and subsequent aspiration pneumonia. Two of those horses suffered from acute gastric ulceration 3-4 days following laparatomy. All horses were treated with cimetidine (5 mg/kg bwt/q.i.d.) until clinical symptoms ceased.

Gelation of mucin: Protecting the stomach from autodigestion

Science.gov (United States)

Bansil, Rama

2011-03-01

In this talk I will describe the molecular mechanisms involved in the remarkable ability of the mucus lining of the stomach for protecting the stomach from being digested by the acidic gastric juices that it secretes. These physical properties can be attributed to the presence of a high molecular weight glycoprotein found in mucus, called mucin. Rheology and other measurements show that gastric mucin forms a gel under acidic pH. A model of gelation based on the interplay of hydrophobic and electrostatic interactions will be discussed. Molecular Dynamics simulation studies of folding and aggregation of mucin domains provide further support for this model. The relevance of gelation to the motion of the ulcer causing bacterium H. pylori will be discussed.

As fistula occurring between the stomach and other abdominal internal organs or to the surface of the body is usually encountered as a complication of stomach cancer or colon cancer, peptic ulcer disease, or other variable causes. The most common type of gastric fistula is a gastro-colic fistula that is mainly found as a complication of a gastric carcinoma or of a carcinoma of the transverse colon invading each other. Sometimes, a benign gastric ulcer perforation also can cause a gastro-colic fistula. However, as far as we know, a fistula occurring between the stomach and the umbilicus has not been reported. Here we present a case report of a gastro-umbilical fistula in a young woman that manifested as a umbilical discharge.

Ganoderma Lucidum Pharmacopuncture for Teating Ethanol-induced Chronic Gastric Ulcers in Rats

Directory of Open Access Journals (Sweden)

Jae-Heung Park

2015-03-01

Full Text Available Objectives: The stomach is a sensitive digestive organ that is susceptible to exogenous pathogens from the diet. In response to such pathogens, the stomach induces oxidative stress, which might be related to the development of both gastric organic disorders such as gastritis, gastric ulcers, and gastric cancer, and functional disorders such as functional dyspepsia. This study was accomplished to investigate the effect of Ganoderma lucidum pharmacopuncture (GLP on chronic gastric ulcers in rats. Methods: The rats were divided into 4 groups of 8 animals each: the normal, the control, the normal saline (NP and the GLP groups. In this study, the modified ethanol gastritis model was used. The rats were administrated 56% ethanol orally every other day. The dose of ethanol was 8 g/kg body weight. The normal group received the same amount of normal saline instead of ethanol. The NP and the GLP groups were treated with injection of saline and GLP respectively. The control group received no treatment. Two local acupoints CV12 (中脘 and ST36 (足三里 were used. All laboratory rats underwent treatment for 15 days. On last day, the rats were sacrificed and their stomachs were immediately excised. Results: Ulcers of the gastric mucosa appeared as elongated bands of hemorrhagic lesions parallel to the long axis of the stomach. In the NP and GLP groups, the injuries to the gastric mucosal injuries were not as severe as they were in the control group. Wound healings of the chronic gastric ulcers was promoted by using GLP and significant alterations of the indices in the gastric mucosa were observed. Such protection was demonstrated by gross appearance, histology and immunehistochemistry staining for Bcl-2-associated X (BAX, B-cell lymphoma 2 (Bcl-2 and Transforming growth factor-beta 1 (TGF-β1. Conclusion: These results suggest that GLP at CV12 and ST36 can provide significant protection to the gastric mucosa against an ethanol induced chronic gastric ulcer.

Control test including gastroscopy with biopsy of the mucous membranes as well as the radioisotopic evaluation of the duodenogastric reflux were conducted on 101 patients after non-resectional operations of the stomach carried out because of an ulcerous disease. The significantly frequent occurrence was confirmed of atrophic gastritis alterations and dysplasia in cases of prevailing reflux. It was proved that the gastroenterostomy as well as the vagotomy with pyloroplasty were operations particularly leading to the rejection into the stomach of the duodenal content. The high selective vagotomy proved to be the operation least including to reflux. The observations made were fully reflected in the histological picture of the operated stomach.

Studying of nitric oxide (NO) dependent mechanisms of regulation of microcirculation in a stomach can provide important diagnostic markers of the development of stress-induced ulcer bleedings. In this work we use a multiscale analysis based on the discrete wavelet-transform to characterize a latent stage of illness formation in rats. A higher sensitivity of stomach vessels to the NO-level in ill rats is discussed.

Gil, M.C.; Godoy, N.; Mena, P.

1985-01-01

The basic aluminium sucrose sulphate complex (Sucralphate), a drug used in the treatment of gastroduodenal ulcer, was labelled with 99 Tcsup(m) by mixing a suspension of the reagent in 0.1 N HCl with HSA, fibrinogen or DTPA labelled with 99 Tcsup(m) or by lyophilizing a suspension containing Sucralphate-HSA-SnCl 2 , Sucralphate-fibrinogen-SnCl 2 , Sucralphate-DTPA-SnCl 2 or Sucralphate-SnCl 2 , which was reconstituted with a saline solution of 99 Tcsup(m)O 4 sup(bar). The radiochemical purity and in vitro stability of labelling were determined by centrifuging. The in vivo affinity of the radiopharmaceutical for the ulcerated zone was studied as a function of the binding agent used in normal and ulcerated rats and the scintigraphic image was evaluated in normal and ulcerated rabbits. Ulcers were induced in rats and rabbits, to which acetylsalicylic acid (600 mg/kg body weight) was administered orally through a stomach probe. The animals had earlier been anaesthetized and kept in a fasting state. The radiopharmaceutical was also administered orally through a stomach probe and the rats and rabbits were sacrificed three hours later. It was established that 99 Tcsup(m)-Sucralphate adhered strongly to the ulcerated gastric mucosa. The scintigraphic image showed slow gastric clearance of the residual pharmaceutical present in the stomach, making interpretation doubtful in some cases. This could possibly be resolved by in situ labelling of the cold drug which had adhered earlier to the ulcerated zone. Preliminary studies with patients indicate that the normal cases can be easily separated; the ulcerous foci can be detected in some patients and darkened images can be obtained for other patients because of the slow gastric clearance. It can be concluded that 99 Tcsup(m)-Sucralphate is a potential radiopharmaceutical for the diagnosis of gastroduodenal ulcer and offers significant advantages over the currently used radiological and endoscopic techniques.

Methods Male swiss albino mice, ulcerated with indomethacin (18 mg/kg, p. o., single dose were treated up to 7 days with different doses of the methanol extract of P. kurroa rhizomes (designated as PK. The healing capacity of the most effective dose of PK (20 mg/kg, p. o. × 3 d was compared with that of omeprazole (Omez (3 mg/kg, p. o. × 3 d. The effects of the drug-treatment for one and three days on the biochemical parameters were assessed by comparing the results with that of untreated mice of the 1st and 3rd day of ulceration. The stomach tissues of the mice were used for the biochemical analysis. Results The macroscopic indices revealed maximum ulceration on the 3rd day after indomethacin administration, which was effectively healed by PK. Under the optimized treatment regime, PK and Omez reduced the ulcer indices by 45.1% (P P Compared to the ulcerated untreated mice, those treated with PK for 3 days showed decreased the levels of thiobarbituric acid reactive substances (TBARS (32.7%, P P P 2 (21.4%, P P P P P P P Conclusion PK (20 mg/kg, p. o. × 3 days could effectively heal indomethacin-induced stomach ulceration in mice by reducing oxidative stress, and promoting mucin secretion, prostaglandin synthesis and augmenting expressions of cyclooxygenase enzymes and growth factors.

Gastric surgery may be performed for the treatment of a variety of benign and malignant diseases of the upper gastrointestinal tract, including peptic ulcers and gastric carcinoma. Radiographic studies with water-soluble contrast agents often are obtained to rule out leaks, obstruction, or other acute complications during the early postoperative period. Barium studies may also be obtained to evaluate for anastomotic strictures or ulcers, bile reflux gastritis, recurrent tumor, or other chronic complications during the late postoperative period. Cross-sectional imaging studies such as CT are also helpful for detecting abscesses or other postoperative collections, recurrent or metastatic tumor, or less common complications such as afferent loop syndrome or gastrojejunal intussusception. It is important for radiologists to be familiar not only with the radiographic findings associated with these various abnormalities but also with the normal appearances of the postoperative stomach on radiographic examinations, so that such appearances are not mistaken for pseudoleaks or other postoperative complications. The purpose of this article is to describe the normal postsurgical anatomy after the most commonly performed operations (including partial gastrectomy, esophagogastrectomy and gastric pull-through, and total gastrectomy and esophagojejunostomy) and to review the acute and chronic complications, normal postoperative findings, and major abnormalities detected on radiographic examinations in these patients.

It is suggested to use metoclopramide (reglan) which is introduced in a dose of 10 ml 10 min before the study intramuscularly at radio X-ray examination of the stomach and duodenum. Peroral application of the drug is not effective. The authors' experience is based on the drug application in 19 healthy persons and 89 patients with the diseases of stomach and duodenum. In patients with gastric ulcer reglan helped in the detection of the niche symptom. The use of the drug facilitated visualization of the pylorus in the case of its organic stenosis. In patients with ulcer of the duodenal bulb after introduction of reglan a better contrasting of the intestine was observed which promoted to the niche detection. An antiemetic property of reglan which can be used in patients, who do not tolerate barium suspension is also pointed out

An Atypical “Hourglass” Stomach Due to the Presence of an Unusual Incisure at the Greater Curvature

Full Text Available Shape and position of the stomach can vary greatly with or without any physiological disturbances. However some of its rare shapes may result in the formation of volvulus or may increase the risk of gastric ulcer. Variant shapes of the stomach may be of congenital occurrence or are acquired later on in life. We report here an atypical form of hourglass stomach. The stomach in the present case exhibited 2 distinct pouches. The two pouches were formed due to the presence of an unusually deep notch at the greater curvature. Both the pouches communicated with the distal end of the esophagus. This variation is possibly of congenital origin and may lead to radiological misinterpretations

In this work the duodenogastric reflux was quantified as the amount of radioactivity entering the stomach after an i.v. administration of sup(99m)Tc-HIDA in ulcer patients and in patients who had undergone BI gastrectomy. The results were compared with visual evidence of gastric activity in the gamma camera images and biochemical determination of gastric bile reflux. The method is useful in quantifying the reflux if the activity is above the background activity. It allows the determination of an upper limit for the reflux when the reflux is evident visually. Only two or three images are needed for the quantitation. No correlation was found between biochemical measurements of fasting bile reflux in the stomach and radioisotopic quantification. (orig.)

99m Tc HIDA was put into use first under standardized conditions in the framework of routinely carried out stomach secretion analyses in order to study the importance of bile reflux in stomach disorders. With this procedure a simple possibility is given in the area of stomach secretion analysis to test if there is a bile reflux to the stomach. Patients with fresh duodenal ulcers had significantly higher reflux rates than those with chronic Ulcus duodeni. After selective proximal vagotomy with submucal pyloro plastic the reflux rates sank in comparison to those before the operation. The color of the aspirate and the reflux values, measured by the here presented procedure, are directly correlated. (TRV) [de

In the present study, we investigate the antiulcerogenic effect of gallic acid against aspirin plus pyrolus ligation-induced gastric ulcer in rats. Rats were treated with gallic acid (100 and 200 mg/kg) and famotidine (20 mg/kg) for 1 week, followed by induction of gastric ulcer using the aspirin plus pyrolus ligation model. At the end of 4 h after ligation, the rats were sacrificed and ulcer index, gastric juice volume, pH and other biochemical parameter of gastric juice were evaluated. Stomachs of rats were evaluated biochemically to determine oxidant and antioxidant parameters. Pretreatment with gallic acid significantly decreased ulcer index, gastric juice volume, free and total acidity, total protein, DNA content and increased pH and carbohydrates concentration. Gallic acid at a dose of 100 and 200 mg/kg exerted 69.7 and 78.9% ulcer inhibition, respectively. The levels of superoxide dismutase, catalase, reduced glutathione, glutathione reductase, glutathione peroxidise, glucose-6-phosphate dehydrogenase were increased while reduction in myeloperoxidase and lipid peroxidation were observed in the stomach tissues of the drug treated rats. The histopathological studies further confirmed the antiulcer activity of gallic acid. We conclude that the gallic acid possesses antiulcer effect and that these occur by a mechanism that involves attenuation of offensive factors, improvement of mucosal defensive with activation of antioxidant parameters and inhibition of some toxic oxidant parameters.

Silviu Stoian

2016-11-01

Full Text Available Heterotopic pancreatic tissue of the stomach is a rare condition. Gastric diverticulum is also a rare condition, mostly located at the fornix. Therefore, the existence of a pyloric gastric diverticulum containing a submucosal tumor proved to be heterotopic pancreatic tissue of the stomach is an extremely rare condition. The patient was a young thin male with epigastralgia chronically treated for gastritis/ulcer. Following an episode of melena, he underwent gastroscopy that diagnosed antral gastric diverticulum containing a polyp. The lesion was surgically removed. The pathology report stated: heterotopic pancreatic tissue of the stomach with secondary development of a traction diverticulum. Heterotopic pancreas tissue of the stomach is a rare condition but the association with gastric diverticulum is completely unusual. The possibility of the ectopic tissue leading to secondary diverticulum development should be considered.

[Pathogenic aspects of stomach ulcerogenesis in acute intestinal obstruction].

Milyukov, V E; Nguen, K K

To identify the patterns and the correlation of morphological and functional changes in stomach wall with the dynamics of different types of acute intestinal obstruction. The study was performed on 33 adult mongrel dogs of both genders weighing 17-20 kg. All researches were conducted in accordance with the documents, such as the 'Guide for the Care and Use of laboratory animals of the National Institute of Health (National Institute of Health - NIH, Bethesda, USA)' and 'Rules of work with experimental animals'. The same methods were used to study the morphology of stomach wall in normal conditions and after intestinal obstruction simulation. We used H & E stain, Van Gieson's picrofuchsin staining combined with Mallory. The choice of histochemical methods was determined by the need to study metabolic processes in epithelial cells and gastric mucosa glands. Einarson method for detecting total nucleic acids was used. The last group of methods was statistical analysis. We determined the regularities of structural organization of microcirculation in various parts of the stomach, the correlation of morphological and functional changes in stomach wall with the dynamics of different types of acute intestinal obstruction. Our data indicate proximal-distal gradient of gastric perfusion: the most pronounced vascular network and maximum blood flow are observed in proximal stomach in both normal conditions and acute intestinal obstruction. More tenuous and reduced blood flow was revealed in the antrum, that is morphological basis of the most frequent localization of acute ulcers in this department.

Sasaki, Kenji

2012-08-28

An 87-year-old, Japanese woman was shown to have a submucosal tumor-like lesion with a deep, central ulceration covered with thick, whitish exudate in the stomach. Biopsy showed Candida tropicalis but not Helicobacter pylori (H. pylori). She had no predisposing factors or history of peptic ulcers nor had taken non-steroidal anti-inflammatory drugs (NSAIDs), diagnosed with Candida-associated gastric ulcer. Though cured of the lesion, she developed another ulcer in a different position, in which Candida was demonstrated but H. pylori was undetectable. This is the first case of recurrent Candida-associated gastric ulcer in the world. Detected in both the original and recurrent lesions in an H. pylori-negative patient with no antecedent ulcers who had not taken NSAIDs, Candida is considered, contrary to the prevailing opinion, to play an etiologic role in ulcer formation.

The present work is an attempt to elucidate the antiulcer activity of indole-3-carbinol (I3C), which is one of the anticarcinogenic phytochemicals found in the vegetables of Cruciferae family such as broccoli and cauliflower, alone or in combination with omeprazole (OMP), a proton pump inhibitor, to diminish the effects of induced acute gastric ulcer by aspirin (ASA) in male albino rats. A total of 48 adult male albino rats were used in the present study. Animals were divided into eight experimental groups (six animals each group). They were given different experimental inductions of ASA at a dose of 500 mg/kg/body weight, OMP at a dose of 20 mg/kg/body weight and I3C at a dose of 20 mg/kg/body weight either alone or in combination with each other orally for a duration of 7 days. Inner stomach features, ulcer index, pH activity, body weight, stomach weight, hematological investigations, serum total protein albumin and reduced glutathione activity were investigated in addition to the histological, histochemical and immunohistochemical stain of cyclooxygenase-2 to the stomach tissue of normal control, ulcerated and treated ulcerated rats. The results of this study revealed that oral administration of ASA to rats produced the expected characteristic mucosal lesions. OMP accelerated ulcer healing but the administration of I3C either alone or in combination with OMP to ASA-ulcerated rats produced a profound protection to the gastric mucosa from injury induced by ASA. Our results suggested that administration of antiulcer natural substances such as I3C in combination with the perused treatment such as OMP is a very important initiative in the development of new strategies in ulcer healing.

AIM: To evaluate the preventive effect of Ginkgo biloba extract (GbE) on ethanol-induced gastric mucosal injuries in rats. METHODS: Female Wistar albino rats were used for the studies. We randomly divided the rats for each study into five subgroups: normal control, experimental control, and three experimental groups. The gastric ulcers were induced by instilling 1 mL 50% ethanol into the stomach. We gave GbE 8.75, 17.5, 26.25 mg/kg intravenously to the experimental groups respectively 30 min prior to the ulcerative challenge. We removed the stomachs 45 min later. The gastric ulcers, gastric mucus and the content of non-protein sulfhydryl groups (NP-SH), malondialdehyde (MDA), c-Jun kinase (JNK) activity in gastric mucosa were evaluated. The amount of gastric juice and its acidity were also measured. RESULTS: The findings of our study are as follows: (1) GbE pretreatment was found to provide a dose-dependent protection against the ethanol-induced gastric ulcers in rats; (2) the GbE pretreatment afforded a dose-dependent inhibition of ethanol-induced depletion of stomach wall mucus, NP-SH contents and increase in the lipid peroxidation (increase MDA) in gastric tissue; (3) gastric ulcer induced by ethanol produced an increase in JNK activity in gastric mucosa which also significantly inhibited by pretreatment with GbE; and (4) GbE alone had no inhibitory effect on gastric secretion in pylorus-ligated rats. CONCLUSION: The finding of this study showed that GbE significantly inhibited the ethanol-induced gastric lesions in rats. We suggest that the preventive effect of GbE may be mediated through: (1) inhibition of lipid peroxidation; (2) preservation of gastric mucus and NP-SH; and (3) blockade of cell apoptosis.

Full Text Available Repeated laser therapy has become an accepted therapeutic approach in the treatment of watermelon stomach, and to date no important negative sequelae have been reported. The case of a patient who underwent repeated sessions of neodymium: yttrium aluminum garnet (Nd:YAG laser therapy over a five-year period for the treatment of the watermelon stomach is presented. Postlaser therapy the patient developed deep ulcerations that would heal; however, he ultimately developed a nodular antrum. Random biopsies of antral nodules revealed carcinoma-in-situ. A Billroth I gastrectomy revealed two foci of carcinoma-in-situ/high grade dysplasia and multiple foci of lower grades of dysplasia. This case suggests a possible association between use of laser therapy and development of gastric neoplasia.

Fluororoentogenography of stomach was carried out on the cases of which stool-test was positive at the time of general physical examinations from October, 1971 to September, 1975. Necessity rate of detailed examination was high in male, but there was no difference by exposure condition between female and male. Rate of detailed examination carried out tended to be high in female, but there was no difference by exposure condition. Rate showing abnormal findings was high in male, and was high in the aged of both female and male. Rate showing abnormal findings according to exposure condition was higher in the group exposed directly to atomic bomb over 2.1 km from the hypocenter, in the group who entered city after explosion, and in other groups than in the group exposed within 2 km from the hypocenter. In findings of the detailed examinations, incidence of gastric ulcer was high in young fellows and male, and incidence of gastric polyp was high in the aged of female. Incidence rate of stomach cancer was high in male, and it increased with increase of age in both female and male. Estimated incidence rate of stomach cancer by exposure condition seemed to be high in the group exposed directly within 1 km from the hypocenter. However, a statistically significant difference was not recognized because of small samples. Incidence rate of stomach cancer by sex was higher in females exposed proximally.

Full Text Available Two different grinding methods - rolling and hammer milling - as well as polyacrylate supplement in the diet were studied to evaluate their effect on the performance of pigs and the incidence of gastric lesions. The experiment was carried out in 2 x 2 factorial arrangement with a total of 160 pigs. The grist size of rolled barley was bigger than of hammermilled barley, but the difference in water-binding capacity was insignificant. No significant differences were observed in the performance traits of pigs fed either rolled or hammer-milled barley. The sodium polyacrylate supplement had no effect on the daily gain, feed:gain ratio or carcass quality of the pigs. Gastric ulcers and constrictions of the oesophageal opening of the stomach were more frequent in the groups fed hammer-milled barley than in the groups fed rolled barley, the difference being statistically significant (P

Actinodaphne sesquipedalis Hook. F. Var. Glabra (Kochummen), also known as “Medang payung” by the Malay people, belongs to the Lauraceae family. In this study, methanol leaf extract of A. sesquipedalis was investigated for their acute toxicity and gastroprotective effects to reduce ulcers in rat stomachs induced by ethanol. The rats were assigned to one of five groups: normal group (group 1), ulcer group (group 2), control positive drug group (group 3) and two experimental groups treated with 150 mg/kg (group 4) and 300 mg/kg (group 5) of leaf extract. The rats were sacrificed an hour after pretreatment with extracts, and their stomach homogenates and tissues were collected for further evaluation. Macroscopic and histological analyses showed that gastric ulcers in rats pretreated with the extract were significantly reduced to an extent that it allowed leukocytes penetration of the gastric walls compared with the ulcer group. In addition, an ulcer inhibition rate of >70% was detected in rats treated with both doses of A. sesquipedalis extract, showing a notable protection of gastric layer. Severe destruction of gastric mucosa was prevented with a high production of mucus and pH gastric contents in both omeprazole-treated and extract-treated groups. Meanwhile, an increase in glycoprotein uptake was observed in pretreated rats through accumulation of magenta color in Periodic Acid Schiff staining assay. Analysis of gastric homogenate from pretreated rats showed a reduction of malondialdehyde and elevation of nitric oxide, glutathione, prostaglandin E2, superoxide dismutase and protein concentration levels in comparison with group 2. Suppression of apoptosis in gastric tissues by upregulation of Hsp70 protein and downregulation of Bax protein was also observed in rats pretreated with extract. Consistent results of a reduction of gastric ulcer and the protection of gastric wall were obtained for rats pretreated with A. sesquipedalis extract, which showed its

Glyprolines have been reported to exert protective effects in the stomach. In this study, we examined the potential effects of intranasal administration of Pro-Gly-Pro (PGP) and N-acetyl-Pro-Gly-Pro (AcPGP) on experimental gastric ulcer formation and healing. We also studied gastric release of the cytokine GRO/CINC-1, and its potential role in ulcer development and healing. Gastric ulcers were induced in rats by applying acetic acid to the serosa of the stomach. PGP and AcPGP were then administered at a dose of 3.7 μmol/kg once daily on either days 1 - 3 (ulcer formation) or days 4 - 6 (ulcer healing). Measurement of ulcer area and histological examination of gastric tissue were carried out on days 4 and 7 after application of acetic acid. In vitro studies involved addition of the glyprolines to cultured rat gastric epithelial cells with or without lipopolysaccharide. Reverse transcription PCR, real-time PCR and ELISA were used for cytokine analysis. PGP and AcPGP significantly reduced ulcer areas on the 4(th) day and accelerated the healing on the 7(th) day compared with the control. After acetic acid-induced ulceration, the expression of GRO/CINC-1 mRNA in gastric tissue was increased 9-fold versus the sham-operated group. Treatment with PGP or AcPGP both significantly suppressed the expression of GRO/CINC-1 mRNA in gastric tissue. However, the glyprolines did not alter LPS-induced mRNA expression or release of GRO/CINC-1 from cultured rat gastric epithelial cells, even though those cells were harvested from rats subjected to the ulcer-induction procedure. The results of this study show that intranasal administration of PGP and AcPGP significantly increased resistance against acetic acid-induced ulceration and accelerated healing in the rats. These effects may be due, at least in part, to their ability to reduce the acetic acid-induced GRO/CINC-1 expression and production in gastric tissue.

Full Text Available This study aimed to describe gastric ulcer in donkeys. 10 donkeys (Equus asinus were studied in Bodonal de la Sierra, Badajoz-Extremadura, Spain. They were referred for necropsy and dead due to non-digestive causes. 4 males and 6 females were examined. The ages were classified of 4-16 years old. The stomach and gastric mucosa was evaluated for classified Merrit, 2003. Samples of gastric tissue were collected. The samples fixed in formalin were processed by conventional histological techniques and examined by histopathology. None of the donkeys presented clinical signs for gastric ulcers syndrome. Of the 10 donkeys studied, 10% had Grade 0; 30% Grade 1; 40% Grade 2; 10% Grade 3; and 10% Grade 4. In 30% (3/10 parasites such as Gasterophilus sp. were observed. The histological slices revealed severe damage on the gastric mucosa, a loss of continuity of the gastric mucosa with corium exposure, and subchorionic edema with parakeratotic hyperkeratosis, together with a mixed lymphoplasmocytic mononuclear infiltrate. In conclusion, we reported gastric ulcers syndrome in donkeys in Spain.

To propose pharmacotherapy of disbacteriosis of gastroduodenal mucous microflora in gastroduodenal inflammation, erosion and ulcer. The study enrolled 30 healthy volunteers, 130 ulcer patients and 36 patients with chronic gastritis (27% of the latter had chronic duodenitis). In addition to general clinical examination, fibrogastroduodenoscopy, we made histological and microbiological examinations of biopsy specimens of the mucosa from different parts of the stomach and duodenum, determined sensitivity of the microflora to antibacterial drugs. We found that recurrent ulcer, chronic gastritis and duodenitis are accompanied with overgrowth of pathogenic microflora in gastric and duodenal mucosa. We developed an effective method of the treatment of gastroduodenal mucosa microflora disbacteriosis in gastroduodenal inflammation, erosion and ulcer including antibacterial, antifungal drugs and probiotics.

Since 1986 403 patients have been treated according to the following programme: successive preparation for surgery, the operative intervention chosen individually for each patient, the purposeful medical rehabilitation. Different types of vagotomy with draining operations were performed in 85.6% of the cases, stomach resection--in 14.4% of the patients. The mortality rate was 0%. The indications for various types of vagotomy, stomach resection and different types of draining operations were determined. Rehabilitation of 55% of the patients after the operative treatment took place at the gastroenterological department, the others--at an outpatient department. The indications for rehabilitation, its volume and time were established. The best remote results in the follow-up periods up to five years were obtained after truncal vagotomy and stomach resection. Ulcer recurrences were noted in 3.5% and 5.2% of the cases respectively. Recurrences of the disease were noted in 7.8% after combined vagotomy and in more than 20% after SPV. Nine patients out of 34 with recurrent ulcers were reoperated with good results, the others were successfully treated by conservative therapy.

Helicobacter pylori adheres to various components of the human saliva. Therefore, the objective of this research was to simultaneously detect H. pylori in saliva and in gastric biopsy, and to determine the agreement between the vacA genotypes in both saliva and gastric biopsy. A total of 162 patients with chronic gastritis and 34 with gastric ulcer were studied, and saliva and biopsy samples were collected from each patient. H. pylori DNA was detected by conventional PCR and nested PCR was used for vacA genotyping. In 24% of the patients (47/196) H. pylori DNA was found in saliva and in biopsy; 52.5% (103/196) were saliva(negative)/biopsy(positive) and 6.6% (13/196) were saliva(positive)/biopsy(negative). In either or both H. pylori vacAs1m1 or s1m2 genotypes were detected in saliva in 41.5% of the patients with chronic gastritis. Forty-seven percent had >1 genotype, and the s1m1/s1m2 combination was found in 36% of them. H. pylori vacAs1m1 and s1m2 were also found in the saliva and biopsy of patients with gastric ulcer. The genotypes found in saliva and biopsy of the same patient had 51.1% agreement. In 27.6% of the 47 patients saliva(positive)/biopsy(positive) two genotypes were found in saliva, and one or both in the stomach. The s1m1/s1m2 genotypes, alone or together, are found simultaneously in saliva and gastric biopsy of the same patient. These results suggest that H. pylori reaches the oral cavity by various ways, and that saliva can be the transmitting and re-infecting vector. Copyright © 2012 Elsevier España, S.L.

[Neurosis and genetic theory of etiology and pathogenesis of ulcer disease].

Science.gov (United States)

Kolotilova, M L; Ivanov, L N

2014-01-01

Based on the analysis of literature data and our own research, we have developed the original concept of etiology and pathogenesis of peptic ulcer disease. An analysis of the literature shows that none of the theories of pathogenesis of peptic ulcer disease does not cover the full diversity of the involved functions and their shifts, which lead to the development of ulcers in the stomach and the duodenum. Our neurogenic-genetic theory of etiology and pathogenesis of gastric ulcer and duodenal ulcer very best explains the cause-and-effect relationships in the patient peptic ulcer, allowing options for predominance in one or the other case factors of neurosis or genetic factors. However, it is clear that the only other: combination of neurogenic factor with genetically modified reactivity of gastroduodenal system (the presence of the target organ) cause the chronicity of the sores. The theory of peptic ulcer disease related to psychosomatic pathologies allows us to develop effective schema therapy, including drugs with psychocorrective action. On the basis of our theory of the role of Helicobacter pylori infection is treated as a pathogenetic factor in the development of peptic ulcer disease.

The aim of the study was to characterize CT images and stages of carcinomas localized in the antral part of the stomach obtained with spiral CT. Seven men aged from 54 years old to 81 years old inclusive, with subjective complaints and clinical suspicion of a neoplasm in the upper gastrointestinal tract were examine Examinations were performed following stomach wall re relaxation with Buscolysin.The stomach is distended by drinking 600 ml of water. Upper abdomen scans were performed with spiral CT/e General Electric with the following parameters: slice thickness 3-5 mm, spacing 3 mm, pitch 1,5, reconstruction index 3 mm. After the pre-contrast scans, 100 ml of non-ionic contrast media is administered intravenously with an injection rate of 30 ml/sec. Scan delay time - 30 seconds after start of injection. Exposition data-120 kV, 180 mAs. Carcinoma localized in the antral part of the stomach was demonstrated in 7 patients. The staging showed: I stage - one patient, II stage - 2, III stage - 1 and IV stage - three patients. According to the macro morphological characteristic: exophytic type - 4, endophytic tumor - 1, ulcerous tumor - 1 and early carcinoma - 1 patient. In our material only male patients were present. Early carcinoma was demonstrated in a male patient at an age of 80 years old. An enhancing nodular local thickness was visualized. Differential diagnosis between malignant and benign ulcer is necessary in certain cases. It is performed on the contrast scans, the malignant process enhances twice its density, When performing a purposive CT examination it is possible to diagnose neoplasms in the antral part of the stomach, from stage i to IV with different macro morphologic characteristic

Changes in gastroduodenal blood flow have been implicated in the pathogenesis of duodenal ulcer. The authors have studied duodenal blood flow during the development of an acute to chronic duodenal ulcer by using the abscopal model, in which ulcers are generated as an indirect effect of lower mediastinal irradiation. Female CFLP mice were randomly allocated to one of three groups. Irradiated ``controls`` received 18 Gy 250 kV X-rays to the upper mediastinum. The lower mediastinum group received the same dose of irradiation, which has been shown to induce typical chronic duodenal ulcers in 45% of animals so treated. Animals were studied by means of radiolabelled microspheres 3 or 7 days later. Proximal duodenal blood flow specifically was reduced by 32% in the lower mediastinum group compared with irradiated controls at 7 days. There was no significant difference in blood flow to the stomach and to the distal duodenum. The decrease in proximal duodenal blood flow in the lower mediastinum group did not differ in the five animals that developed ulcer compared with the seven that did not. Although, there is an overall decrease in duodenal blood flow associated with chronic duodenal ulcer, reduced blood flow may not explain individual susceptibility to ulceration. 21 refs., 1 fig., 2 tabs.

Antiulcer activity of fluvoxamine in rats and its effect on oxidant and antioxidant parameters in stomach tissue

Science.gov (United States)

2009-01-01

Background Although many drugs are available for the treatment of gastric ulcers, often these drugs are ineffective. Many antidepressant drugs have been shown to have antiulcer activity in various models of experimental ulcer. One such drug, the antidepressant mirtazapine, has been reported to have an antiulcer effect that involves an increase in antioxidant, and a decrease in oxidant, parameters. To date, however, there is no information available regarding the antiulcer activity for a similar antidepressant, fluvoxamine. This study aimed to investigate the antiulcer effects of fluvoxamine and to determine its relationship with antioxidants. Methods Groups of rats fasted for 24 h received fluvoxamine (25, 50, 100 and 200 mg/kg), ranitidine (50 mg/kg) or distilled water by oral gavage. Indomethacin (25 mg/kg) was orally administered to the rats as an ulcerative agent. Six hours after ulcer induction, the stomachs of the rats were excised and an ulcer index determined. Separate groups of rats were treated with the same doses of fluvoxamine and ranitidine, but not with indomethacin, to test effects of these drugs alone on biochemical parameters. The stomachs were evaluated biochemically to determine oxidant and antioxidant parameters. We used one-way ANOVA and least significant difference (LSD) options for data analysis. Results The 25, 50, 100 and 200 mg/kg doses of fluvoxamine exerted antiulcer effects of 48.5, 67.5, 82.1 and 96.1%, respectively, compared to the control rat group. Ranitidine showed an 86.5% antiulcer effect. No differences were observed in the absence of indomethacin treatment for any dose of fluvoxamine or for ranitidine. The levels of antioxidant parameters, total glutathione and nitric oxide, were increased in all fluvoxamine groups and in the ranitidine group when compared with the indomethacin-only group. In addition, fluvoxamine and ranitidine decreased the levels of the oxidant parameters, myeloperoxidase and malondialdeyhyde, in the stomach

15-hydroxyprostaglandin dehydrogenase (15-PGDH) is the enzyme responsible for prostaglandins (PGs) metabolism. PGs have an important role in the protection of stomach mucosa against destructive stimuli. The aim of the present study is to investigate the inhibitory effect of carbenoxolone, pioglitazone and verapamil on 15-PGDH enzyme. The experiments were carried out in the Faculty of Pharmacy, Suez Canal University, Ismailia, Egypt from May 2011 to August 2011. Adult male albino rats were fasted for 18 hours before administration of high dose of indomethacin (30 mg/kg, p.o.), except for the negative control group which received saline only, followed by pyloric ligation to induce acute gastric ulcers. The rats were pretreated orally with saline, pioglitazone (20 mg/kg), verapamil (25 mg/kg), carbenoxolone (30 mg/kg) or their combinations 30 minutes before indomethacin. The rats were sacrificed after four hours of pyloric ligation. The effects of the previous treatments on the ulcer index (Ui), the microscopic appearance of gastric mucosa, the gastric acid output, the gastric barrier mucus content, and 15-PGDH enzyme activity were determined. Indomethacin resulted in severe ulceration and increased gastric acid output (p ulcer index, gastric acid output and 15-PGDH activity (p ulcer index, gastric acid output and 15-PGDH activity (p stomach mucosa.

The physical form of diets has a marked impact on the development of gastric ulcers in pigs. Earlier studies showed effects of fine grinding and pelleting on the integrity of gastric mucosa as well as on local intragastric milieu. This study was conducted to evaluate the effects of dry or liquid feeding on intragastric milieu (DM and pH) in pigs. The 23 piglets were housed individually and fed with test diets and water ad lib for 6 wk. Both experimental diets [coarsely ground diet fed as mash (CM) vs. finely ground pelleted diet (FP)] were identical in ingredients (39.5% wheat, 34% barley, 20% soybean meal) and chemical composition and were either offered dry or in liquid (25% DM) form. At the end of the trial the animals were slaughtered; the stomach was removed and samples were taken from different localizations. Feeding diets dry or liquid had no effect on the pH (P > 0.05). The diet noticeably affected the gastric content. The FP diets resulted in a more liquid chyme (P pH did not differ between regions. Feeding CM caused marked effects of localization regarding pH (highest values: pars nonglandularis; lowest values: fundus). None of the pigs fed CM showed signs of gastric ulcers, but the score was markedly higher (P < 0.05) when pigs were fed FP. Therefore the predominant factor for development of gastric ulcers seems to be the structure (particle size) of the diet.

Is It Worthwhile to Fully Evaluate the Stomach in Every Ultrasound Examination of the Abdominal Cavity?

Goudarzi, M.; Navabi, J.; Salimi, Gh.

2011-01-01

To evaluate the usefulness of abdominal sonography in the fasting state with no hypotonic agents in the detection and exclusion of gastric lesions. One-hundred patients with normal upper gastrointestinal endoscopy, 94 patients with a major gastric abnormality (including 59 intraluminal tumors, three submucosal masses, 29 ulcers, two polyps and one hypertrophied gastric mucosa) and 75 patients with minor gastric abnormalities (mainly gastritis) were enrolled into the study. Of the 100 normal patients, ultrasound showed four false positive results with 96% specificity of the examination. Within the major gastric lesion group, ultrasound was true positive in 55 of 59 tumors, 15 of 29 ulcers, three of three submucosal masses and the case of giant gastric mucosa. It was negative in the detection of gastric polyps. It could detect only 8% of minor gastric abnormalities. Abdominal sonography in the fasting state, if carefully performed, is sufficiently accurate in detection and exclusion of major gastric lesions. Therefore, although it cannot replace endoscopic and barium studies of the stomach, careful evaluation of the stomach is recommended in every sonographic evaluation of the abdominal cavity

Although proximal gastrectomy has become a procedure of choice for patients' early cancer in the upper third of stomach, no clinical guide for optimal gastric resection in order to avoid postoperative jejunal ulcer is available. The aim of this study was to investigate whether determining the distribution of parietal and chief cells of the stomach using Congo red test is clinically relevant. The F-line was defined as a boundary line between fundic and intermediate area of the stomach according to the pathological findings in 29 patients who underwent total gastrectomy for early gastric cancer, whereas the f-line was regarded as a boundary line between intermediate and pyloric area. In the additional 6 patients undergoing vagus-preserving proximal gastrectomy with jejunal pouch interposition, endoscopic Congo red test was preoperatively performed to determine the F-f-line. The distances from the pyloric ring to f-line on the lesser and greater curvatures were variable. Long-term outcomes of proximal gastrectomy guided by preoperative endoscopic Congo red test were favorable. It is suggested that preoperative endoscopic Congo red test is useful to determine the appropriate cutting line in order to avoid postoperative jejunal ulcer after proximal gastrectomy.

An analysis was done for the diagnostic accuracy of radiological and endoscopic examinations in 132 cases of the histologically proved stomach cancer at the national Medical Center from Jan. 1975 to Jan. 1979. The problem in radiological misdiagnosis was especially discussed aimed to improve the further diagnostic accuracy. The following results were obtained: 1. The incidence of the stomach cancer was higher in male than that of female, and was most prevalent in 5th and 6th decades. 2. The misdiagnosis rate of radiological examination of the stomach cancer was 13.5% (18 cases), that of endoscopic examination was 8.3% (11 cases) and that of both examination was 4.6% (6 cases). 3. In most cases of misdiagnosis, the majority were diagnosed as benign gastric ulcer. 4. The causative factors of misdiagnosis in radiological examination were interpretation error in 8 cases and technically poor, unsatisfactory study in 10 cases. 5. In order to decrease the misdiagnosis rate, standardization of radiological examination and careful interpretation are necessary. 6. Complementary examinations of radiology and endoscopy can decrease the misdiagnosis rate.

The UGI studies had been performed to 238 patients below the age of 15 years during the period from Jan. 1979 to Jul. 1983 in SCH hospital. The results are as follows: 1. Among 238 cases, 48 cases revealed peptic ulcers of stomach or duodenum (20.2%). The ulcer was in 31/37 cases of male patients (22.6%), and in 17/101 cases of female (16.8). Below the age of 5 years, ulcer was noted in 9 cases among 61 cases (14.8%), whereas above 5 years, in 39 cases among 177 patients (22.0%). 2. In the age group below 5 years, mostly the objective symptoms were discovered (8/9), but above 5 years, complained of subjective symptoms (30/39). 3. The predominant site of peptic ulcer was gastric antrum in the age group below 5 years (7/9), whereas duodenal bulb above 5 years (33/43). 4. Gastric antrum or duodenal bulb deformity was revealed in 13 cases and most of them were in the age group above 5 years. 5. All lesions of peptic ulcers in this study were benign in nature. 6. In follow up study after 1 or 2 months, ulcer was decreased in size strikingly (9/11)

Patients with upper abdominal pain are often examined with both double contrast study of the stomach and endoscopy. On the basis of the results of the two examinations four diagnostic criteria of an ulcer can be formed: 1) radiography reveals an ulcer, 2) endoscopy reveals an ulcer, 3) both radiography and endoscopy reveal an ulcer, and 4) radiography and/or endoscopy reveals an ulcer. In a prospective study the accuracy of each of the four diagnostic criteria was examined. Eighty-two randomly selected outpatients had a double contrast barium examination and an upper gastrointestinal endoscopy performed by staff personnel. The diagnosis of a specialist in upper gastrointestinal endoscopy was used as the standard. For the four diagnostic criteria the overall accuracy ranged from 0.80 to 0.88. The predictive value of a positive test result was around 0.70 and the predictive value of a negative test result ranged from 0.81 to 0.96. The specificity ranged from 0.87 to 0.95, and the sensitivity from 0.38 to 0.90. It is concluded that from a clinical point of view, the accuracy of the four diagnostic criteria does not differ to an extent that justifies recommendation of one diagnostic criterion of gastric ulcer rather than the other.

The purpose of this study was to investigate the effect of astaxanthin extracted from Paracoccus carotinifaciens on gastric mucosal damage in murine gastric ulcer models. Mice were pretreated with astaxanthin for 1 h before ulcer induction. Gastric ulcers were induced in mice by oral administration of hydrochloride (HCl)/ethanol or acidified aspirin. The effect of astaxanthin on lipid peroxidation in murine stomach homogenates was also evaluated by measuring the level of thiobarbituric acid reactive substance (TBARS). The free radical scavenging activities of astaxanthin were also measured by electron spin resonance (ESR) measurements. Astaxanthin significantly decreased the extent of HCl/ethanol- and acidified aspirin-induced gastric ulcers. Astaxanthin also decreased the level of TBARS. The ESR measurement showed that astaxanthin had radical scavenging activities against the 1,1-diphenyl-2-picrylhydrazyl radical and the superoxide anion radical. These results suggest that astaxanthin has antioxidant properties and exerts a protective effect against ulcer formation in murine models. Copyright © 2011 John Wiley & Sons, Ltd.

Hyptis suaveolens is used by the traditional population in several parts of the world to treat inflammation, gastric ulcer and infection and is used as a crude drug to relieve symptoms related with gastric ulcer or gastritis in northeaster and central region of Brazil. the standardized ethanolic extract (Hs-EtOHE) and hexanic fraction (Hs-HexF) of Hyptis suaveolens (62,5, 125, 250 and 500 mg/kg) was evaluated in several models of acute gastric ulcers. The participation of NO was evaluated by pretreatment with L-NAME and non-protein sulfyhydryls by NEM in the gastroprotective effect. Hs-EtOHE and Hs-HexF markedly reduced the gastric lesions induced by all ulcerogenic agents (HCl/ethanol, ethanol, NSAIDs and hypothermic restraint-stress). Gastric ulcerations were exacerbated by administration of NEM suggesting that the gastroprotective mechanism of action of Hs-EtOHE and Hs-HexF involves sulfhydryl groups. Ours results show that an extract of Hyptis suaveolens, administered orally to rodents, present gastro protective activity in different models of acute of gastric ulcer and give some support to the reported claims on the use of this plant as a gastro protective agent. © 2013 Published by Elsevier Ireland Ltd.

[Treatment and prevention of erosive and ulcerative lesions in the stomach and duodenum caused by intake of non-steroidalanti-inflammatory drugs].

Luzina, E V

2014-01-01

Therapy with non-steroidal anti-inflammatory drugs (NSAIDs) is a diffcult task. Good anti-inflammatory effect increases the risk of gastrointestinal complications with a frequency of 10-50%. The risk further increases with age (above 60-70 yr), the history of ulcer disease concomitant intake of acetylsalicylic acid, anticoagulants, and glucocorticosteroids. Long-term antisecretory therapy with proton pump inhibitors, e.g., esomeprazole, was shown to be an effective prophylactic tool. This drug maintains the intragastric pH value above 4 for 15 hr on the average. The risk of erosive and ulceraive lesions in the stomach and duodenum significantly decreases by selective cyclooxygenase-2 inhibitors, e.g., coxibs, that however increase the risk of thrombotic cardiovascular complications. The author proposes recommendations on the use of NSAIDs in the patients at risk of serious gastrointestinal and cardiovascular pathology. Naproxen in combination with proton pitmp inhibitors is the drug of choice among NSAIDs. Vimovo is a fixed combination of naproxen and esomeprazole. Results of comparative studies on the efficacy of vimovo and celecoxib are presented along with the data on the safety of this. combination compared with that of naproxen monotherapy

Abstract Although endoscopic ultrasonography (EUS) is the first-choice imaging modality for predicting the invasion depth of early gastric cancer (EGC), the prediction accuracy of EUS is significantly decreased when EGC is combined with ulceration. The aim of present study was to compare the accuracy of EUS and conventional endoscopy (CE) for determining the depth of EGC. In addition, the various clinic-pathologic factors affecting the diagnostic accuracy of EUS, with a particular focus on endoscopic ulcer shapes, were evaluated. We retrospectively reviewed data from 236 consecutive patients with ulcerative EGC. All patients underwent EUS for estimating tumor invasion depth, followed by either curative surgery or endoscopic treatment. The diagnostic accuracy of EUS and CE was evaluated by comparing the final histologic result of resected specimen. The correlation between accuracy of EUS and characteristics of EGC (tumor size, histology, location in stomach, tumor invasion depth, and endoscopic ulcer shapes) was analyzed. Endoscopic ulcer shapes were classified into 3 groups: definite ulcer, superficial ulcer, and ill-defined ulcer. The overall accuracy of EUS and CE for predicting the invasion depth in ulcerative EGC was 68.6% and 55.5%, respectively. Of the 236 patients, 36 patients were classified as definite ulcers, 98 were superficial ulcers, and 102 were ill-defined ulcers, In univariate analysis, EUS accuracy was associated with invasion depth (P = 0.023), tumor size (P = 0.034), and endoscopic ulcer shapes (P = 0.001). In multivariate analysis, there is a significant association between superficial ulcer in CE and EUS accuracy (odds ratio: 2.977; 95% confidence interval: 1.255–7.064; P = 0.013). The accuracy of EUS for determining tumor invasion depth in ulcerative EGC was superior to that of CE. In addition, ulcer shape was an important factor that affected EUS accuracy. PMID:27472672

Diffuse reflection spectra of biotissues in vivo and transmission and reflection coefficients for biotissues in vitro are measured over 300-800 nm. These data are used to determine the spectral absorption and scattering indices and the scattering anisotropy factor for stomach mucous membranes under normal and various pathological conditions (chronic atrophic and ulcerous defects, malignant neoplasms). The most importan tphysiological (hemodynamic and oxygenation levels) and structural-morphological (scatterer size and density) parameters are also determined. The results of a morphofunctional study correlate well with the optical properties and are consistent with data from a histomorphological analysis of the corresponding tissues.

To evaluate the prevalence of lesions and digestive complications secondary to the use of non-steroidal anti-inflammatory drugs (NSAIDs), the clinical profile seen for digestive complaints and the relation with the endoscopic findings. Prospective, multicentric, open study, evaluating consecutively 1231 patients, divided as follows: group I - NSAID and group II - non-NSAID. All patients answered questionnaire to evaluate the onset, the type of clinical complaint, the use of medication and possible complications associated to digestive bleeding. RESULTS. A total of 1213 patients were evaluated. Among them, 65% were female and 13.1% were smokers; 15.6% mentioned they ingested alcoholic beverages. The main signs and symptoms reported were epigastralgy and pyrosis (67% and 62%, respectively). The upper gastrointestinal (UGI) endoscopy was normal in 3.9% in group I and in 10.7% in group II (p < 0.001). Patient who do not use NSAID will be 2.5 times more likely to have normal UGI endoscopy (p = 0.001). The presence of erosive or ulcer lesions in the stomach and duodenum was more frequent in group I. The incidence of lesions in the stomach when compared to the duodenum is observed (erosions: 49.12% vs. 13.60%, p = 0.001; ulcers: 14.04% vs. 11.84%, p = 0.05). The risk of digestive bleeding is 12 times higher (6.14% vs. 0.51%) in those who used NSAIDs, and the stomach is the site in which bleeding occurs more frequently. Conclusions. The frequency of gastric ulcer, duodenal ulcer and digestive bleeding was higher in patients who used NSAIDs. There was no connection found between endoscopic findings and dyspeptic symptoms.

Full Text Available The present study aims to investigate the gastroprotective effect of Brucea javanica oil emulsion (BJOE in animals. Gastroprotective potential of BJOE was studied on absolute ethanol, aspirin, reserpine and restraint plus water immersion-induced gastric ulcers in mice as well as glacial acetic acid (GAA and pyloric ligation (PL-induced gastric ulcers in rats. Except for ulcer scores, total acidity as well as pepsin activity as for the PL-induced gastric ulcer model and ulcer incidence as for the GAA-induced gastric ulcer model were also determined. Histopathological evaluation as for aspirin, reserpine, PL-induced models was conducted. Results showed that BJOE significantly (P < 0.05 reduced ulcer index in the mouse and rat models in a dose-dependent manner. It had significant (P < 0.05 suppressive effect on total activity of gastric juice as well in PL-induced model. Histopathological examination for the stomach samples confirmed the findings in the aspirin, reserpine or PL-induced gastric lesion models, which showed relatively complete mucosa structure and less inflammation. It is concluded that BJOE could be effective on gastric ulcer in rodents and its gastroprotective activity might be related to antioxidant, anti-inflammatory ability and promote gastric mucus secreted. The results may provide beneficial basis for increasing BJOE's clinical indication in future.

Full Text Available Ewing sarcoma/primitive neuroectodermal tumor (ES/PNET is a tumor of small round cells arising in skeletal tissues. These tumors rarely arise in the stomach. We present a 31-year-old healthy female patient who was admitted to our surgical ward due to upper gastrointestinal hemorrhage. Upper endoscopy revealed a large ulcerated bleeding mass originating from the lesser curvature. Biopsy revealed tumor cell immunoreactivity positive for CD99, vimentin, and Ki67 (an index of proliferation. These findings were compatible with gastric ES/PNET. The fluorescence in situ hybridization analysis result for the EWSR1 gene rearrangement (11: 22 translocation was positive. The patient refused neoadjuvant treatment and thus underwent an operation during which a mass at the lesser curvature of the stomach was found. The mass was adhering to the pancreatic tail and to the mesentery of the transverse and descending colon. Total gastrectomy, distal pancreatectomy, splenectomy, and left adrenalectomy were done. The patient refused adjuvant treatment. She is free of disease 3 years after surgery.

Control test including gastroscopy with biopsy of the mucous membranes as well as the radioisotopic evaluation of the duodenogastric reflux were conducted on 101 patients after non-resectional operations of the stomach carried out because of an ulcerous disease. The significantly frequent occurrence was confirmed of atrophic gastritis alterations and dysplasia in cases of prevailing reflux. It was proved that the gastroenterostomy as well as the vagotomy with pyloroplasty were operations particularly leading to the rejection into the stomach of the duodenal content. The high selective vagotomy proved to be the operation least including to reflux. The observations made were fully reflected in the histological picture of the operated stomach.

The current study was designed to investigate the protective effect of kefir milk on ethanol-induced gastric ulcers in γ-irradiated rats. The results of the present study revealed that treatment with γ-irradiation and/or ethanol showed a significant increase in ulcers number, total acidity, peptic, H(+)K(+)ATPase, MMP-2 and MMP-9 activities and MDA level, which were accompanied by a significant decrease in the mucus content, the stomach GSH level, the GSH-Px activity and DNA damage. Pre-treatment with kefir milk exert significant improvement in all the tested parameters. Kefir milk exerts comparable effect to that of the antiulcer drug ranitidine. In conclusion, the present study revealed that oral administration of kefir milk prevents ethanol-induced gastric ulcer in γ-irradiated rats that could attribute to its antioxidant, anti-apoptotic and radio-protective activities.

Implications of Helicobacter pylori infection for stomach cancer prevention

Directory of Open Access Journals (Sweden)

Goodman Karen J.

1997-01-01

Full Text Available Accumulating evidence has implicated Helicobacter pylori, an established cause of chronic gastritis and peptic ulcer, in the etiology of gastric cancer. Control of this infection would reduce the occurrence of chronic gastritis and peptic ulcer and might substantially lower the risk of stomach cancer as well. The public health impact of this infectious agent warrants efforts to identify preventive measures. This paper reviews the evidence linking H. pylori infection to gastric cancer and evaluates the potential for control in high-risk populations. Current obstacles to H. pylori control are discussed, including the link to poor socioeconomic conditions, difficulty in identifying incident cases, lack of natural immunity to reinfection, limited effectiveness of antibiotic therapy in high-prevalence populations, and incomplete knowledge regarding the reservoir of infection, mode of transmission, host susceptibility factors, and the potential for developing an effective vaccine. Worthwhile avenues of research include studies designed to identify modifiable risk factors for acquisition of the infection, modifiable host factors that may increase resistance to chronic infection, more effective antibiotic therapies, and effective vaccines.

Therapeutic gastric irradiation has been used to reduce peptic juice secretion in patients with peptic ulcer disease. Between 1937 and 1968 a total of 2049 patients received such therapy at the University of Chicago. Three of these patients are known to have developed sarcomas in the field of radiation. Two gastric leiomyosarcomas of the stomach were diagnosed 26 and 14 years after treatment and a malignant fibrous histiocytoma of the anterior chest wall was removed six years after gastric irradiation. Of 743 peptic ulcer patients treated without irradiation and constituted as a control group for the study of therapeutic gastric radiation, none is known to have developed sarcoma. As the incidence of sarcoma in these patient groups is known only from the tumor registry of the University of Chicago, other cases of sarcoma may exist in the groups. While an increased incidence of sarcoma has not been proven to occur in patients who received therapeutic gastric irradiation for peptic ulcer disease, the possibility of such a risk should be borne in mind by physicians caring for such patients

Dragon-pearl tea is a type of green tea commonly consumed in Southwest China. In the present study, the antioxidative and anti-gastric ulcer effects of Dragon-pearl tea crude polyphenols (DTCP) were determined in vitro and in vivo . Treatment with 25, 50 or 100 µg/ml DTCP resulted in notable antioxidant effects in vitro , which manifested as 2,2-diphenyl-1-picrylhydrazyl and OH radical-scavenging activity. Furthermore, using an in vivo mouse model, DTCP was shown to reduce the gastric ulcer area in the stomach, in which the 200 mg/kg DTCP dose exhibited the most marked effect, with a gastric ulcer index inhibitory rate of 72.63%. In addition, DTCP was demonstrated to improve stomach acidity conditions in vivo by increasing the pH and reducing the level of gastric juice, as compared with the reserpine-induced gastric ulcer control mice. Furthermore, DTCP altered the serum levels of a number of oxidation-related biomolecules, including superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), malondialdehyde (MDA), lipid peroxidation (LPO) and catalase (CAT), to subsequently exert an anti-gastric ulcer effect. Treatment with 50, 100 and 200 mg/kg DTCP increased the SOD, GSH-Px and CAT levels and reduced the MDA and LPO levels in the mouse model of gastric ulcers. These serum level alterations resulted in the modified serum levels of prostaglandin E2 (PGE2) and nitric oxide (NO), which are associated with gastric mucosal protection. A reverse transcription-quantitative polymerase chain reaction (RT-PCR) assay is a molecular biology experiment which could determine the changes of mRNA in tissues. Using the RT-PCR assay, DTCP was observed to increase the mRNA expression levels of certain genes associated with gastric ulcers: Epidermal growth factor, epidermal growth factor receptor, vascular endothelial growth factor and vascular endothelial growth factor receptor 1, while reducing gastrin expression levels. Therefore, the results indicated that DTCP induced a

In the following article, we will discuss general issues relating to acute and late gastric's radiation toxicities. The tolerance of the stomach to complete or partial organ irradiation is more un-appreciated than for most other organs. We consulted the Medline database via PubMed and used the key words gastric - radiotherapy - toxicity. Currently, 60 Gy or less is prescribed in gastric radiation therapy. Acute clinical toxicity symptoms are predominantly nausea and vomiting. Although there is a general agreement that the whole stomach tolerance is for doses of 40 to 45 Gy without unacceptable complication, it is well established that a stomach dose of 35 Gy increases the risk of ulcer complications.

Rise and fall of peptic ulceration: A disease of civilization?

Science.gov (United States)

Roberts-Thomson, Ian C

2018-07-01

Humans and Helicobacter pylori have evolved and adapted over tens of thousands of years. Yet peptic ulcer disease appeared to be rare prior to the 19th century. The prevalence of peptic ulcer disease increased between 1850 and 1900 and culminated in a cohort at high risk that was born at the end of the 19th century. This coincided with the provision of safe water and improvements in sanitation and personal hygiene. One hypothesis for the emergence of peptic ulcer disease focuses on the rate of development of atrophic gastritis induced by H. pylori. The hypothesis developed in this article focuses on delay in the age of acquisition of H. pylori to a time when immune and inflammatory responses to the infection were more mature. Whereas the acquisition of H. pylori in infancy usually resulted in mild pangastritis, hypochlorhydria, and a low risk for peptic ulcer disease, delayed acquisition could cause either more severe pangastritis (predisposing to gastric ulceration) or gastritis largely restricted to the antrum of the stomach (predisposing to duodenal ulceration). The decline in the prevalence of peptic ulcer disease over the past 100 years parallels the decline in the prevalence of H. pylori. The epidemic of ulcer disease in the first half of the 20th century seems likely to be an adverse effect of important public health measures undertaken in the latter half of the 19th century. © 2018 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

Little information exists regarding the optimal treatment of early gastric cancer (EGC) in a remnant stomach or gastric tube. The aim of this study was to assess the feasibility and clinical outcomes of endoscopic submucosal dissection (ESD) for EGC in a remnant stomach and gastric tube. Between September 2002 and December 2009, ESD was performed in 62 lesions in 59 patients with EGC in a remnant stomach (48 lesions) or gastric tube (14 lesions). Clinicopathological data were retrieved retrospectively to assess the en bloc resection rate, complications, and outcomes. Treatment results were assessed according to the indications for endoscopic resection, and were compared with those of ESD performed in a whole stomach during the same study period. The en bloc resection rates for lesions within the standard and expanded indication were 100 % and 93 %, respectively. Postoperative bleeding occurred in five patients (8 %). The perforation rate was significantly higher (18 %, 11 /62) than that of ESD in a whole stomach (5 %, 69 /1479). Among the perforation cases, eight lesions involved the anastomotic site or stump line, and ulcerative changes were observed in five lesions. The 3-year overall survival rate was 85 %, with eight deaths due to other causes and no deaths from gastric cancer. A high en bloc resection rate was achieved by ESD for EGC in a remnant stomach or gastric tube; however, this procedure is still technically demanding due to the high complication rate of perforation. © Georg Thieme Verlag KG Stuttgart · New York.

Anatomical distribution of peptic ulcer in high incidence gastric cancer area

Full Text Available Background: Peptic ulcer makes reference to the solution of continuity of gastric or duodenal wall beyond muscularis mucosae. Previously, duodenal location was more common than gastric, in a ratio ranging from 2:1 to 4:1. Despite this, after the discovery of the association between peptic ulcer and Helicobacter pylori, relationship between gastric and duodenal ulcer has spread to the equality. However, in areas with high incidence of gastric cancer, peptic ulcer seems to have a different behavior, existing predominance of gastric ulcer. Department of Cauca is have the highest incidence of gastric cancer in Colombia, with an annual rate of 42.5 /100,000 for males and 28.6 / 100,000 for women; however, it is unknown how peptic ulcer anatomically are distributed. Objective: To determine the anatomical distribution of peptic ulcer at endoscopy service of San José University Hospital of Popayán-Cauca, Colombia 2006-2012. Methods: A descriptive cross-sectional study was realized. Database of endoscopy service of San José University Hospital of Popayán was reviewed and reports with diagnosis of peptic ulcer were studied. Data were analyzed using SPSS-15. Results: Gastric ulcer was more common than duodenal ulcer. Gastric ulcer was more common in men (gastric and duodenal ulcer 1:1. In women duodenal ulcer is 1:1. Conclusion: At endoscopy service of San José University Hospital, gastric ulcer is more common than duodenal ulcer, with differences in gender, as in other areas with high incidence of gastric cancer. That fact are suggests in current literature could be related with the presence of stumps of Helicobacter pylori with combined virulence for cancer and ulcer at gastric level seems to be related to the presence in the medium of common virulence strains of Helicobacter pylori for stomach cancer and ulcer gastric, although the current literature is unclear about it, and still needs more validations.

=26). Assessment of various predefined postures and behaviours was made by an observer blind to the gastric ulcer status of the observed pigs. Behavioural data from the two sites were combined in a single analysis. Pigs with gastric ulcers tended to spend less time idle (P=0.081) and less time lying...... on their left side (P=0.064), and significantly more time standing (P=0.009), or walking (P=0.038) compared to healthy pigs. Pigs with ulcers also showed an increased frequency of posture changes (P=0.02). A decrease in time spent lying on the left and an increase in standing/walking could both be interpreted...... as attempts to avoid liquid gastric contents pooling in the cranial region of the stomach. This along with the higher level of posture changes observed may indicate some degree of pain/discomfort associated with the presence of gastric ulcers in pigs. This study is the first to identify apparent behavioural...

This study was performed to determine if and for how long sucralfate (SU) binds selectively to sites of gastro-intestinal (GI) ulceration. Se-Su was prepared by sulfating sucrose with tracer Se-75 and precipitating it as the basic Al salt. All patients (pts) had endoscopy to confirm the presence of either: esophagitis (n=5), gastritis (GA) (n=5), gastric ulcers (GU) (n=5), duodenal ulcers (DU) (n=5), or no ulceration (NU) (n=5). Following an overnight fast the pts swallowed 1 gm with 100 ..mu..Ci of Se-SU and were imaged continuously over 24 hours or until no activity remained in the upper GI tract. Pts with GU visually demonstrated focal SU binding at the ulcers for an average of 3.9 +- 1.1 hrs. with a mean GET of 68 +- 25 min. Mean GET for pts with DU was prolonged, 171 +- 63 min, however focal binding at duodenal ulcers was not seen. All pts with GA had diffuse retention of SU in the stomach with a mean GET of 118 +- 34 min. Focal binding of SU at all sites of esophagitis was seen with a T-1/2 of 65 +- 32 min at the ulcerations. In conclusion these data support the theory that the mechanism of ulcer healing with SU is related to its ability to adhere to the ulcer site forming a protective barrier. In addition Se-SU is a potential ulcer imaging agent which can be used to noninvasively assess healing.

Steady-state fluorescence and diffuse reflection spectra are measured for in vivo normal and pathological (chronic atrophic and ulcerating defects, malignant neoplasms) stomach mucous lining tissues. The degree of distortion of the fluorescence spectra is estimated taking light scattering and absorption into account. A combination of Gauss and Lorentz functions is used to decompose the fluorescence spectra. Potential groups of fluorophores are determined and indices are introduced to characterize the dynamics of their contributions to the resultant spectra as pathologies develop. Reabsorption is found to quench the fluorescence of structural proteins by as much as a factor of 3, while scattering of the light can increase the fluorescence intensity of flavin and prophyrin groups by as much as a factor of 2.

Stomach as a source of colonization of the respiratory tract during mechanical ventilation: association with ventilator-associated pneumonia.

The aetiopathogenesis of ventilator-associated pneumonia (VAP) requires abnormal oropharyngeal and gastric colonization and the further aspiration of their contents to the lower airways. VAP develops easily if aspiration or inoculation of microorganisms occur in patients with artificial airways, in whom mechanical, cellular and/or humoral defences are altered. Well-known risk factors for gastric colonization include: alterations in gastric juice secretion; alkalinization of gastric contents; administration of enteral nutrition; and the presence of bilirubin. However, the role of the colonized gastric reservoir in the development of VAP remains debatable. Evidence in favour of the role of the stomach in the development of VAP comes mainly from randomized, controlled trials of selective gut decontamination and stress ulcer prophylaxis in the intensive care unit (ICU), in which reducing the bacterial burden of the stomach decreases the incidence of nosocomial respiratory infections. However, at least three studies of flora have found an absence of stomach origin of pneumonia occurring during mechanical ventilation. Prophylactic measures suggested to prevent VAP in relation to the gastric reservoir include: treatment for stress ulcers with sucralfate; prevention of duodenal reflux with metoclopramide; reduction of gastric burden and bacterial translocation by selective digestive decontamination; acidification of enteral feeding; and jejunal feeding. Gastro-oesophageal reflux can be prevented by using small bore nasogastric tubes and jejunal feeding. The aspiration of gastric contents can be reduced by positioning patients in a semirecumbent position, checking the patency of the tube cuff, and aspiration of subglottic secretions. The role of the stomach as a reservoir for microorganisms causing ventilator-associated pneumonia is still controversial but despite the debate, there is major evidence in the literature in favour of the gastric origin of part of these

Malignant tumors have received much attention as delayed effects of A-bomb radiation. Above all, it is of a major concern to determine how the incidence of stomach cancer, commonly observed among Japanese, is influenced by A-bomb radiation. This article focusses on the relationship between A-bomb radiation and the incidence of stomach cancer, and its histological features with a brief review of the literature. Mass screening for stomach cancer has showed in 1973 that the incidence of stomach cancer is definitely high among the heavily exposed A-bomb survivors. Since then, data analyses using the T65DR have showed it to be higher in the 100 rad exposed group than the 0 rad exposed group. On the basis of death certificates, the incidence of stomach cancer is found to be increased around 1976. When using DS86, the calculated lowest dose that produces a significantly high mortality incidence from stomach cancer is 1 Gy at the sheilding kerma and 0.5 Gy at organ absorbed dose. Histopathologically, the incidence of poorly differentiated adenocarcinoma is increased with increasing radiation doses; it is significantly increased in the 1 rad exposed group. The incidence of medullary type is decreased and the incidence of scirrhous type is increased with increasing radiation doses. (N.K.)

Radioimmunologic assays of blood serum carcinoembryonic antigen (CEA) level were conducted at major stages of treatment of gastric cancer by subtotal stomach resection and gastrectomy with preliminary cryotreatment and thawing of tumor. A short-term rise in CEA level occurred in 53.9 % of cases 3-4 days after combined therapy. A decrease in CEA concentration at discharge from hospital as compared with preoperative level and that registered 3-4 days after operation was observed in 50 and 75 % of cases of combined therapy, respectively, and 47.5 and 37.5 % of controls (surgery without cryotreatment). There was nocorrelation between cryotreatment and changes in CEA level in gastric ulcer patients

A study on the diagnosis of carcinoma of the stomach was carried out in 105 selected Korean cases of histologically proved carcinoma of the stomach, aimed to the position and value of roentgenography and gastroscopy. The results were summarized as follows: 1) In the diagnosis of 105 cases of Korean gastric carcinomas, a correct diagnosis was made by roentgenography in 79.1 percent and by gastroscopy in 86.7 percent of all cases. Roentgenography plus gastroscopy permitted a correct diagnosis in 92.3 percent of all cases. There is no significant difference statistically on the diagnostic accuracy between roentgenography and gastroscopy (by t-test, t=0.8572). 2) In the diagnosis of carcinoma of the stomach, with roentgenography the greatest diagnostic error occurred in primary ulcerative lesions and with gastroscopy in inadequate examinations which were resulted from mechanical failures. It occurred also in mixed type of infiltration and ulceration for the gross pathology and in lesions of gastric body and pyloric antrum as the site of the lesion. 3) In this series of 105 cases of Korean gastric carcinomas, two cases of early gastric carcinoma (type IIc +III) were correctly diagnosed by roentgenography and gastroscopy. 4) In this series, the most frequent type of gross pathology appeared to be Bormann tpe III, type of ulceration with spreading infiltration, which was 72.4 percent of all 105 cases and the site of the lesion revealed the highest frequently in the pylorus in 53.3 percent, but both of these had little significance in the determination of diagnostic accuracy of roentgenography and/or gastroscopy in gastric carcinomas. 5) The onset of symptoms, clinical manifestations, and physical findings were reviewed in all 105 cases of this series. The predominant symptoms were epigastric pain (75.2 percent), indigestion (73.3 percent) and weight lose (57.0 percent) in the order and the most frequent physical findings was epigastric tenderness (68.6 percent).

A study of the effect of propolis against gastric ulcers induced in gamma -irradiated rats

International Nuclear Information System (INIS)

Abd El-Aziz, R.R

2009-01-01

The anti-ulcerogenic activity of propolis or bee glue, a natural product from honey bees, was investigated against indomethacin -induced gastric ulcers in non- irradiated and irradiated rats, and the effects were compared with those of the proton pump inhibitor lansoprazole, as a reference anti-ulcerogenic drug. Indomethacin-induced gastric ulcer was used in this study as a model of experimentally induced gastric ulceration. The anti-ulcerogenic, antisecretory and cytoprotective activities of 13% aqueous propolis extract (APE) were assessed. Gastric contents of animals were sampled for the measurement of free acidity, acid output, mucin and pepsin concentrations in the gastric juice. The stomach was examined macroscopically for the determination of the ulcer index. PGE 2 was assayed in the gastric mucosa, while the pro-inflammatory cytokines TNF-α and IL-1β as well as the oxidative stress marker MDA were determined in the plasma.

The study was intended to develop a new intra-gastric floating in situ microballoons system for controlled delivery of rabeprazole sodium and amoxicillin trihydrate for the treatment of peptic ulcer disease. Eudragit S-100 and hydroxypropyl methyl cellulose based low density microballoons systems were fabricated by employing varying concentrations of Eudragit S-100 and hydroxypropyl methyl cellulose, to which varying concentrations of drug was added, and formulated by stirring at various speed and time to optimize the process and formulation variable. The formulation variables like concentration and ratio of polymers significantly affected the in vitro drug release from the prepared floating device. The validation of the gastro-retentive potential of the prepared microballoons was carried out in rabbits by orally administration of microballoons formulation containing radio opaque material. The developed formulations showed improved buoyancy and lower ulcer index as compared to that seen with plain drugs. Ulcer protective efficacies were confirmed in ulcer-bearing mouse model. In conclusion, greater compatibility, higher gastro-retention and higher anti-ulcer activity of the presently fabricated formulations to improve potential of formulation for redefining ulcer treatment are presented here. These learning exposed a targeted and sustained drug delivery potential of prepared microballoons in gastric region for ulcer therapeutic intervention as corroborated by in vitro and in vivo findings and, thus, deserves further attention for improved ulcer treatment.

Parton, Amanda T; Volk, Susan W; Weisse, Chick

2006-06-15

CASE DESCRIPTION-An 8-year-old castrated male German Shepherd Dog was evaluated because of abdominal distension, retching, and vomiting. CLINICAL FINDINGS-Gastric dilatation-volvulus was suspected on the basis of the dog's signalment, history, clinical signs, and results of clinicopathologic analyses and abdominal radiography. Celiotomy was performed, and gastric dilatation-volvulus was confirmed along with splenomegaly. Gastric invagination was performed over an area of gastric necrosis. The dog was reevaluated 21 days later after an episode of collapse. Findings of physical examination and clinicopathologic analyses were suggestive of internal hemorrhage. Abdominal ultrasonography and subsequent celiotomy revealed severe gastric ulceration at the gastric invagination site, splenic torsion, and a focal splenic infarct. TREATMENT AND OUTCOME-Splenectomy and gastrectomy of the necrotic tissue were performed. The dog was discharged from the hospital, and the owner was instructed to administer gastroprotectants and feed the dog a bland diet. The dog was reported to be healthy 3.25 years after surgery. CLINICAL RELEVANCE-Findings suggest that complications associated with the gastric invagination procedure include severe gastric ulceration that may require subsequent surgery. Prolonged treatment with gastroprotectants following gastric invagination surgery may be necessary to avoid gastric ulceration in dogs.

1990-01-01

A new method for diagnosing the Campylobacter Pylori in the stomach is described, using C-14 settled urease. Campylobacter Pylori is now being considered the most probable causative agent of antral chronic gastritis, pepitic ulcer and non-ulcerous dyspepsia. The technique is based on ingestion of the tracer, its recovery by exhalation in etanol hyamine solution, followed by counting and dates evaluation. The test was applied to forty two voluntary male and female patients, after their written acquiescence. Their ages varied from 19 to 62 years old. Thirty of the results were positive and twelve negative. All of them were comproved by microbiological (cultura) and hystologycal studies of gastric biopsy gotten by gastroscopy. They were performed at the Gastroentherology Departament of the 'Hospital das Clinicas' that belongs to the Federal University of Minas Gerais. Repetitivity of the breath test was confirmed by repetition of the results in five positive patients and five negative ones. (author) [pt

Many clinicians believe hypercortisolism is ulcerogenic. However, data from clinical studies show that prophylaxis for peptic ulcer disease is no longer recommended in patients receiving corticosteroid treatment. This has not yet been verified in endogenous hypercortisolism by controlled clinical studies. The purpose of the current study was to evaluate the relationship between endogenous Cushing's syndrome (CS) and peptic ulcer disease and Helicobacter pylori infection. The study group contained 20 cases with CS resulting from ACTH-dependent endogenous hypercortisolism. The control groups consisted of 14 age- and gender-matched cases receiving exogenous corticosteroid therapy and 100 cases of dyspepsia with non-cushingoid features. Upper gastrointestinal endoscopy was performed on all cases. Biopsies were taken from five different points: two samples from the antrum, two samples from the corpus, and one sample from the fundus. A histological diagnosis of Helicobacter pylori infection was also obtained from evaluation of biopsy specimens. The frequency of stomach and duodenal ulcers did not vary between the groups (p = 0.5 and p = 0.7). Antral gastritis was less frequent and pangastritis was more common in cases with CS compared to the healthy controls (p = 0.001 and p peptic ulcer or Helicobacter pylori infection. Prophylactic use of proton pump inhibitors is not compulsory for hypercortisolism of any type.

Alternative types of duodenal ulcer induced in mice by partial X irradiation of the thorax

The present study extends our earlier observations on gastrointestinal pathology in thorax-irradiated female CFLP mice. It shows that exposure of the lower mediastinum to single doses of 14-30 Gy X rays results in the formation of the proximal duodenal ulcer accompanied frequently by erosion of the antral gastric mucosa. X irradiation of the lateral thoracic fields is responsible for single ulcers in the proximity of duodenal papilla, often associated with a circumscribed area of degeneration of the fundic mucosa of the stomach. In view of the small amount of radiation received by the subdiaphragmatic parts of the alimentary tract, these gastro-duodenal lesions represent abscopal effects of thoracic irradiation

Helicobacter pylori genotyping from positive clotests in patients with duodenal ulcer

2000-01-01

Full Text Available Even though the seroprevalence of H. pylori may be high in the normal population, a minority develops peptic ulcer. Colonization of the gastric mucosa by more pathogenic vacA strains of H. pylori seems to be associated with enhanced gastric inflammation and duodenal ulcer. H. pylori genotyping from positive CLOtests was developed to determine the vacA genotypes and cagA status in 40 duodenal ulcer patients and for routine use. The pathogenic s1b/ m1/ cagA genotype was the most frequently occurring strain (17/42.5%; only two (5% patients presented the s2/ m2 genotype, the less virulent strain. Multiple strains were also detected in 17 (42.5% patients. Multiple strains of H. pylori colonizing the human stomach have been underestimated, because genotyping has been performed from cultures of H. pylori. We concluded that genotyping of H. pylori from a positive CLOtest had the advantages of reducing the number of biopsies taken during endoscopy, eliminating the step of culturing H. pylori, and assuring the presence of H. pylori in the specimen being processed.

Peptic Ulcer at the End of the 20th Century: Biological and Psychological Risk Factors

Directory of Open Access Journals (Sweden)

Susan Levenstein

1999-01-01

Full Text Available The prevailing concept of peptic ulcer etiology has swung over entirely in just a few years from the psychological to the infectious, yet the rich literature documenting an association between psychosocial factors and ulcer is not invalidated by the discovery of Helicobacter pylori. Physical and psychological stressors interact to induce ulcers in animal models, concrete life difficulties and subjective distress predict the development of ulcers in prospective cohorts, shared catastrophes such as war and earthquakes lead to surges in hospitalizations for complicated ulcers, and stress or anxiety can worsen ulcer course. Many known ulcer risk factors, including smoking, nonsteroidal anti-inflammatory drug use, heavy drinking, loss of sleep and skipping breakfast, can increase under stress; the association of low socioeconomic status with ulcer is also accounted for in part by psychosocial factors. Among possible physiological mechanisms, stress may induce gastric hypersecretion, reduce acid buffering in the stomach and the duodenum, impair gastroduodenal blood flow, and affect healing or inflammation through psychoneuroimmunological mechanisms. Psychosocial factors seem to be particularly prominent among idiopathic or complicated ulcers, but they are probably operative in run of the mill H pylori disease as well, either through additive effects or by facilitating the spread of the organism across the pylorus, while gastrointestinal damage by nonsteroidal anti-inflammatory drugs can also be potentiated by stress. Although the clinical importance of peptic ulcer is fading along with the millenium, due to secular trends and new therapies, it remains worthy of study as a splendid example of the biopsychosocial model.

A serosa-searing apparatus for producing gastric ulcer in rats.

Kagoshima, M; Suzuki, T; Katagiri, S; Shimada, H

1994-12-01

Chronic ulcer models produced by serosa-searing method are very similar histologically to the ulcer healing process occurring in humans. In an effort to produce a serosa-searing chronic ulcer model in rats, we devised a new balance-type apparatus. This searing apparatus is capable of changing adequately both temperature and duration of time. Furthermore, the pressure which serves to bring the searing iron tip into contact with the stomach serosa surface can also be precisely changed. Optimal conditions for reproducing the serosa-searing ulcer model were at 65 degrees C and in 5 sec. Moreover, in order to evaluate the effects of pressure, various pressure levels (A: 5 g, 17.68 g/cm2; B: 10 g, 35.37 g/cm2; C: 15 g, 53.05 g/cm2; D: 20 g, 70.74 g/cm2; E: 25 g, 88.42 g/cm2; F: 30 g, 106.10 g/cm2; G: 35 g, 123.79 g/cm2 (+/- 1 g, 0.149 g/cm2)) of 5-sec duration at 65 +/- 0.1 degrees C were used. Macroscopically, gastric mucosal lesions were most clearly observed in a pressure-related manner 7 days after the procedure. Histologically, definite deep ulcerations (UI-III or UI-IV) were observed at pressure level C (15 g, 53.05 g/cm2) or more. The highest incidence (87%) of histological gastric ulcers (UI-IV) was observed in pressure level E (25 g, 88.42 g/cm2). The healing process was observed at 40 to 60 days postoperatively. At 100 days after the procedure, recurrences were observed both macroscopically and histologically.

Lactase deficiency (LD) has been described in associated with peptic ulcer disease of the upper gastrointestinal tract, but little has been known as to the incidence of LD in the patients with ulcer disease of the upper GI tract or with gastric carcinoma. The purpose of the present study is to investigate the incidence of LD in gastric and/or duodenal ulcer disease and in gastric carcinoma, and to hypothesize the possible effect of these diseases on LD. Clinical materials consisted of 40 cases of active duodenal ulcer disease, 19 cases of benign gastric ulcer, 5 cases of multiple ulcers both in the stomach and duodenum, and 32 cases of gastric carcinoma. We used the lactose-barium test in diagnosing LD. X-ray findings were assessed according to the criteria described by Laws et al. and Preger and Amberg in the small-bowel film obtained at 30 minutes after the ingestion of some 200 ml of lactose-barium meal which contained 50 gm of lactose. Our clinical study revealed that the incidence of LD in duodenal ulcer was 50%, in gastric ulcer 57.9%, in gastric and duodenal ulcer 60%, and in gastric carcinoma 46.9%. The difference of incidence between each disease were statistically not significant, but the difference between the disease group and normal control was highly significant. The incidence of LD in disease group was nearly twice as high as that of normal control (27.7%). It is speculated that high incidence of LD in peptic ulcer disease of upper GI tract in particular may be associated with high acidity, the analog of which is found in Zollinger-Ellison syndrome. But high acidity is not a prominent feature in gastric carcinoma which is attended by almost equally high incidence of LD. It is therefore likely that the intolerability to lactose is caused by much complicated mechanism of versatile factors

The authors developed and evaluated a new procedure for imaging gastric ulcer disease with technetium 99m - labeled sucralfate. The new method employs direct in vivo labeling of sucralfate instead of in vitro labeling using human serum albumin, as previously reported in the literature. In 26 studies using humans with sucralfate labeled directly in vivo, 15 gave true-negative results. Of 14 studies using humans with in vitro labeled sucralfate, three gave true-negative results, three gave true-positive results, and the results of eight were either false-negative or could not be interpreted because of high levels of activity remaining in the stomach. They suggest that the direct in vivo labeling method significantly improves the sucralfate gastric ulcer imaging technique.

Despite decreasing Helicobacter pylori prevalence, the prevalence of peptic ulcer disease is increasing in the aged population, mainly due to increasing use of NSAIDs to manage pain and inflammation. In addition, low dose aspirin is employed as an anti-coagulant for those who have suffered or are at high risk of ischemic stroke and cardiovascular disease. However, NSAIDs and aspirin are injurious to mucosa of stomach and duodenum. NSAID-induced inhibition of mucosal prostaglandin synthesis is thought to be a major mechanism of gastrointestinal mucosal injury. The proportion of elderly has increased rapidly in Korea, with the proportion over 65 years old expected to be 24.3% in 2030. In this higher-risk population, the strategy to reduce the incidence of NSAID-related peptic ulcers and complications such as bleeding, obstruction and perforation is very important. Proton pump inhibitors (PPIs) with cyclooxygenase-2 inhibitor can be used for reducing the risk of NSAID-related ulcers and upper gastrointestinal (GI) complications. However, continuous use of PPI has several problems. In addition, NSAID-related problems in the lower GI tract have increased, in contrast to the decrease of NSAID-related upper GI disease. The aim of this review is to provide an evidence-based knowledge regarding the mechanism, complications of treatment, and prevention strategies for NSAID- or aspirin-related peptic ulcer disease in Korea.

The strains of Helicobacter pylori are described by many common features which determine their virulence. The genes which are connected with much higher virulence of some strains are vacA, cagA, oipA, dupA. Duodenal Ulcer Promoting Gene--dupA is the new virulence factor coexisting with a duodenum ulcer. There is a rationale that shows a protective character of dupA with reference to a stomach cancer. The dupA gene probably causes increasingly higher releasing of pro-infectious IL-8 via stomach cells and it influences the production of IL-12 and other cytokines. The aim of the study was to determine the frequency of dupA gene's appearance in the Polish children's group and in the Polish teenagers' group infected with H. pylori. The research was also aimed to determine the coexistence of dupA gene and duodenum ulcer disease or erosion infection of duodenum's mucous membrane. The endoscopic examination of the upper part of digestive duct was performed in 119 qualified patients with dyspeptic symptoms and with suspicion of stomach and duodenum's mucous membrane infection. The segments were taken for histopathological identification of H. pylori and for genetic indicating via PCR method. To confirm the presence of H. pylori in the extract the amplification of DNA fragment sized 860 pz was used. The presence of dupA gene was detected by PCR reaction with using the starters which include the fragment of jhp0917-jhp0918 sequence in the plastic H. pylori's genome area. To confirm the infection the urea breathing test was taken. 88 patients confirm the infection of H. pylori. The presence of dupA gene was found in 20 patients--a group A (22.7%), whereas in 68 patients dupA gene was not found--a group B (77.2%). Pathological changes in duodenum was found in 20 patients infected with H. pylori (22.7%), included 4 patients in the group A (20%) and 16 in the group B (23.5%). There was an infection (swelling, redness, congestion) in duodenum was found in the group A in all cases

Stall housing has been suggested as a risk factor for ulcer development in the equine stomach; however, the exact pathogenesis for this has not been established. To investigate the effect of 3 environmental situations (grass paddock, stall alone or stall with adjacent companion) on pH in the proximal and the ventral stomach. Six horses with permanently implanted gastric cannulae were used in a randomised, cross-over, block design. Each horse rotated through each of three 24 h environmental situations. Horses remained on their normal diet (grass hay ad libitum and grain b.i.d.) throughout the study. Intragastric pH was measured continuously for 72 h just inside the lower oesophageal sphincter (proximal stomach) and via a pH probe in the gastric cannula (ventral stomach). Neither proximal nor ventral 24 h gastric pH changed significantly between the 3 environmental situations. Mean hourly proximal gastric pH decreased significantly in the interval from 01.00-09.00 h compared to the interval from 13.00-20.00 h, regardless of environmental situation. Median hourly proximal pH only differed in the interval from 06.00-07.00 h compared to the interval 14.00-19.00 h. Neither mean nor median hourly ventral gastric pH varied significantly with the time of day. The change in housing status used in the current study did not affect acid exposure within either region of the equine stomach. The pH in the ventral stomach was uniformly stable throughout the study, while the proximal pH demonstrated a 24 h circadian pattern.

We studied 135 people (24 people, apparently healthy, 39 uncomplicated peptic ulcer disease, 42 people with complex forms peptic ulcer, 30 and after the treatment of complicated forms of peptic ulcer disease, both sexes (18-45 y.). In all patients, the diagnosis was confirmed fibrogastroduodenoscopy (EGD). Determination of histones and acid soluble fraction (ASF), RNA, DNA, in blood was performed by the method of L. Markusheva. Studies have led to the conclusion that the change in the blood concentration of extracellular nucleic acids in patients with uncomplicated disease and complex shapes can be caused by oxidative stress products and can be a signal for elimination of nucleic acids from cells. We have registered various dynamics of the studied parameters histones in the blood of patients with various forms of peptic ulcer disease, which reflects the degree of metabolic abnormalities that occur in the body, associated with changes in the structure of the nucleus. According to the results of our research in the study of the role of extracellular nucleic acids, histones to assess the extent of violations of metabolic processes at a peptic ulcer, complicated and uncomplicated form, the obtained results can be used as predictors of complications of a stomach ulcer.

Curcumin is known to possess anti‑inflammatory properties. Despite the fact that curcumin is known to be a strong inhibitor of H+, K+‑ATPase activity, the mechanism underlying the curcumin‑induced inhibition of the transcription of the H+, K+‑ATPase α subunit in gastric mucosal parietal cells remains unclear. The present study investigated the possible mechanism by which curcumin inhibits stomach H+, K+‑ATPase activity during the acute phase of gastric ulcer disease. A rat model of stress‑induced gastric ulcers was produced, in which the anti‑ulcer effects of curcumin were examined. Curcumin‑induced inhibition of the H+, K+‑ATPase promoter via histone acetylation, was verified using a chromatin immunoprecipitation assay. The results showed that curcumin improved stress‑induced gastric ulcer disease in rats, as demonstrated by increased pH values and reduced gastric mucosal hemorrhage and ulcer index. These effects were accompanied by a significant reduction in the level of histone H3 acetylation at the site of the H+, K+‑ATPase promoter and in the expression of the gastric H+,K+‑ATPase α subunit gene and protein. In conclusion, curcumin downregulated the acetylation of histone H3 at the site of the H+, K+‑ATPase promoter gene, thereby inhibiting the transcription and expression of the H+, K+‑ATPase gene. Curcumin was shown to have a preventive and therapeutic effect in gastric ulcer disease.

Studies assessing the effect and mechanism of probiotics on diseases of the upper gastrointestinal tract (GI) including gastric ulcers are limited despite extensive work and promising results of this therapeutic option for other GI diseases. In this study, we investigated the mechanisms by which the probiotic mixture VSL#3 (a mixture of eight probiotic bacteria including Lactobacilli, Bifidobacteria and Streptococcus species) heals acetic acid induced gastric ulcer in rats. VSL#3 was administered orally at low (6×109 bacteria) or high (1.2×1010 bacteria) dosages from day 3 after ulcer induction for 14 consecutive days. VSL#3 treatments significantly enhanced gastric ulcer healing in a dose-dependent manner. To assess the mechanism(s) whereby VSL#3 exerted its protective effects, we quantified the gene expression of several pro-inflammatory cytokines, protein and expression of stomach mucin-Muc5ac, regulatory cytokine-IL-10, COX-2 and various growth factors. Of all the components examined, only expression and protein production of VEGF was increased 332-fold on day 7 in the ulcerated tissues of animals treated with VSL#3. Predictably, animals treated with VEGF neutralizing antibody significantly delayed gastric ulcer healing in VSL#3 treated animals. This is the first report to demonstrate high efficacy of the probiotic mixture VSL#3 in enhancing gastric ulcer healing. Probiotic efficacy was effective at higher concentrations of VSL#3 by specifically increasing the expression and production of angiogenesis promoting growth factors, primarily VEGF. PMID:23484048

Escin, a natural mixture of triterpenoid saponin isolated from the seed of the horse chestnut, is reported to have a potent antiulcer activity against ethanol-induced gastric mucosal lesions. This study investigated the possible mechanisms underlying the gastroprotective effect of escin against indomethacin-induced gastric ulcer in mice. Gastric ulceration was induced by a single intragastric administration of indomethacin (18 mg/kg). The mice underwent intragastric treatment with escin at doses of 0.45, 0.9 or 1.8 mg/kg. Gastric lesion was estimated morphometrically and histopathologically 6 h after the indomethacin administration. The antioxidative parameters in gastric mucosa were measured. Moreover, the activity of myeloperoxidase and the contents of TNF-α, P-selectin and VCAM-1 in gastric tissues were determined. The results showed that escin protected gastric tissues against indomethacin-induced gastropathy as demonstrated from a reduction in the ulcer index and an attenuation of histopathologic changes. Escin caused significant reductions of the contents of malondialdehyde, TNF-α, P-selectin, VCAM-1 and myeloperoxidase activity. The altered activities of superoxide dismutase, catalase and glutathione peroxidase in the stomach tissues were also ameliorated by escin treatment. The present study demonstrated that escin had a protective effect against indomethacin-induced gastric ulcer in mice, not only by virtue of its antioxidant potential, but also due to its anti-inflammatory effect.

To Improve the diagnosis of duodenal ulcer and preneoplastic changes of gastroduodenal transition. 112 patients with duodenal ulcer, 208 healthy pearsons of three age periods: second period of mature age, elderly and senile age were examined. Video endoscopy equipment company "OLYMPUS" (Japan), morphological methods and the determination of Helicobacter pylori (Hp) were used. The connecting line of gastric and duodenal mucous membrane can be located on the gastric side of the pylorus (13% in normal cases and 22.3% in cases of ulcer disease), on pylorus and go into the bulbus of duodenum (87% and 77.7 %, respectively), in cases of duodenal ulcer the connecting line more often has jagged and tongue-shaped form. Mucous membrane forms folds in prepyloric part of the stomach most often on the front wall in healthy pearsons in 14.4% of cases, in patients with duodenal ulcer--in 75.9%. The number of folds decreases with age. HP, atrophy, intestinal metaplasia of the mucous membrane is more often found in duodenal ulcer disease--76.8%, 69.7% and 62.5% comparing with healthy persons: 51.4%, 5.3% and 47.7% respectively. Frequency of preneoplastic changes increases with age. The individual differences of the mucous membrane of the gastroduodenal transition are identified. They are expressed in the particular location and shape of the connecting line of gastric and duodenal mucous membranes in normal cases and in cases of ulcer disease in different age groups. Some endoscopic changes requiring biopsy and morphological studies are revealed.

Hericium erinaceus is a famous tonic in oriental medicine. The gastroprotective effects of aqueous extract of H. erinaceus against ethanol-induced ulcers in Sprague Dawley rats were investigated. The possible involvements of lipid peroxidation, superoxide dismutase, and catalase were also investigated. Acute toxicity study was performed. The effects of aqueous extract of H. erinaceus on the ulcer areas, ulcer inhibition, gastric wall mucus, gross and histological gastric lesions, antioxidant levels, and malondialdehyde (MDA) contents were evaluated in ethanol-induced ulcer in vivo. In acute toxicity study, a high dose of 5 g/kg did not manifest any toxicological signs in rats. The extract promoted ulcer protection as ascertained by a significant reduction of the ulcer area. Furthermore, it exhibited a significant protection activity against gastric mucosal injury by preventing the depletion of antioxidant enzymes. The level of MDA was also limited in rat stomach tissues when compared with the ulcer control group. Immunohistochemistry showed upregulation of HSP70 protein and downregulation of BAX protein in rats pretreated with the extract. The aqueous extract of H. erinaceus protected gastric mucosa in our in vivo model. It is speculated that the bioactive compounds present in the extract may play a major role in gastroprotective activity. PMID:24302966

Lycopene, the main antioxidant compound present in tomatoes, has high singlet oxygen- and peroxyl radicals-quenching ability, resulting in protection against oxidative damage in aerobic cell. Indomethacin is a nonsteroidal anti-inflammatory drug, and can promote oxidative damage in gastric tissue. The aim of this study was to investigate the protective effects of lycopene on an indomethacin-induced gastric ulcer model. A total of 42 adult male Wistar rats were divided into six groups of seven animals as follows: control, indomethacin, lansoprazole, lycopene 10 mg/kg, lycopene 50 mg/kg and lycopene 100 mg/kg. Gastric ulcers were induced by oral administration of indomethacin, after which the differing doses of lycopene were administered by oral gavage. The efficacy of lycopene was compared with lansoprazole. DNA damage of lymphocytes was measured by comet assay. Activities of superoxide dismutase, catalase and myeloperoxidase, as well as malondialdehyde and glutathione levels were determined in stomach tissue. This tissue was also taken for pathological investigations. The TUNEL method was used to detect apoptotic cells in paraffin sections. The results showed that 100 mg/kg lycopene administration significantly decreased % Tail DNA and Mean Tail Moment in the gastric ulcer group, compared with the other treatment groups. This same dose of lycopene also significantly decreased high malondialdehyde level and myeloperoxidase activity, and increased the activity of antioxidant enzymes (with the exception of catalase) in tissue. Apoptosis rates in the stomachs of the rats correlated with the biochemical and histopathological findings. These results indicated that lycopene might have a protective effect against indomethacin-induced gastric ulcer and oxidative stress in rats.

Senecio candicans DC (Asteraceae) is used as a remedy for gastric ulcer and stomach pain in the Nilgiris district, Tamil Nadu for which no scientific evidence exists. The present study was performed to evaluate the gastroprotective effects and acute oral toxicity of aqueous leaf extract of Senecio candicans (AESC) in experimental models. The antiulcerogenic activity of AESC was performed in two different ulcer models viz., pylorus-ligated model and ethanol-induced model using Wistar albino rats. Acute toxicity study was also performed to get information on the admissible dose for treatment of ulcer. Preliminary phytochemical screening of AESC was performed to find the active principles present, which are thus responsible for the antiulcerogenic activity. DPPH assay was performed to confirm the antioxidant activity of AESC. The acute toxicity study did not show any mortality up to 2500mg/kg b.w. of AESC. Both the ulcer models showed gastroprotective effect comparable to that of the standard Omeprazole. The results of antioxidant enzymes, histopathology sections, ATPase and mucus content of gastric secretion showed that several mechanisms are involved in the gastroprotective effect. The preliminary phytochemical screening revealed the presence of alkaloids, flavonoids and steroids in AESC. The DPPH assay confirmed the antioxidant activity of AESC. The traditional consumption of AESC for the treatment of gastric ulcer is thus true, the antioxidant constituents present in the extract plays a major role in the gastroprotective activity, but since Senecio species are known for the presence of pyrrolizidine alkaloids, a detailed study in future is required to describe the safe dose for a prolonged period.

The healing activity of black tea (BT) and BT fermented with Candida parapsilosis and kombucha culture, designated as CT and KT respectively against the indomethacin-induced stomach ulceration has been studied in a mouse model. The KT sample (KT4) produced by fermenting BT for four days, showed the best DPPH radical scavenging capacity and phenolics contents. Hence the ulcer-healing activity of KT4 was compared with those of CT4 and BT. All the tea extracts (15 mg kg(-1)) could effectively heal the gastric ulceration as revealed from the histopathological and biochemical studies, with relative efficacy as KT4 > CT4 ∼ BT. The healing capacities of the tea extracts could be attributed to their antioxidant activity as well as the ability to protect the mucin content of the gastric tissues. In addition, the ability of KT4 to reduce gastric acid secretion might also contribute to its ulcer-healing activity. The tea preparation KT4 (15 mg kg(-1)) was as effective as the positive control, omeprazole (3 mg kg(-1)) in ulcer healing.

It has been reported that proton beam therapy is an effective treatment method for patients with locally confined esophageal cancer. However, there seems to be serious problems related to post-radiotherapy (RT) esophageal ulcers. We treated 7 patients who developed post-RT esophageal ulcers with the earliest symptom of esophageal stenosis, which was observed 7-17 months (median, 10.0) after completion of RT. Five of the patients had unhealed ulcers leading to lethal events such as perforation or penetration. The mean time between the appearance of the earliest symptom and lethal episode was no more than 2 months (mean, 2.1). The first 3 patients who underwent conservative therapies died from severe complications caused by perforation or penetration of post-RT esophageal ulcers. In the case of 2 consecutive patients, we performed surgical treatment as soon as possible since there were indications of penetration in post-RT developed esophageal ulcers. Therefore, they could be cured by a salvage operation which was subtotal esophagectomy using the stomach for esophageal replacement. Through the above-mentioned experience, we discussed surgical management for esophageal ulcers after proton beam therapy. (author)

Acute bleeding from the upper gastrointestinal system is a medical emergency which is followed by high mortality rate, ranging from 6 to 15% in spite of modern diagnostic methods and treatment. Bleeding from the upper gastrointestinal system may be caused by gastrointestinal stromal tumors of the stomach, which are mainly characterized by occult bleeding, while profuse bleeding rarely occurs accompanied by hemorrhagic shock. Gastrointestinal stromal tumors of stomach are the most common mesenchimal tumors of the gastrointestinal tract. In our study we showed a 60-year-old female patient with profuse bleeding from the stomach and the clinical picture of severe hemorrhagic shock, caused by gastrointestinal stromal tumor. An ovoid junction, raised towards the lumen, covered with ulcerated mucosa in several places and followed by massive arterial bleeding was found intraoperatively, after the performed gastrotomy. Histopathological examination with immunohistochemical analysis confirmed that this was a gastrointestinal stromal tumor of the stomach. Acute bleeding from the digestive system is a sudden and serious condition of the body. Urgent esophagogastroduodenoscopy is a sensitive and specific diagnostic and therapeutic method of choice. Massive bleeding from the upper gastrointestinal tract is very rarely caused by gastrointestinal stromal tumors, whose clinical picture is very heterogeneous and depends on tumor size and location. Abundant bleeding from the tumor is an indication for urgent surgical intervention. According to the literature massive hemorrhage of the upper digestive system can rarely be caused by gastrointestinal stromal tumor of the stomach. It is shown that abundant hemorrhage of the upper digestive tract can be caused with gastric gastrointestinal stromal tumor. Surgical resection is the main form of treatment of gastrointestinal stromal tumors of the digestive system and bleeding from these tumors caused by failure of endoscopic hemostasis.

Full Text Available Hericium erinaceus is a famous tonic in oriental medicine. The gastroprotective effects of aqueous extract of H. erinaceus against ethanol-induced ulcers in Sprague Dawley rats were investigated. The possible involvements of lipid peroxidation, superoxide dismutase, and catalase were also investigated. Acute toxicity study was performed. The effects of aqueous extract of H. erinaceus on the ulcer areas, ulcer inhibition, gastric wall mucus, gross and histological gastric lesions, antioxidant levels, and malondialdehyde (MDA contents were evaluated in ethanol-induced ulcer in vivo. In acute toxicity study, a high dose of 5 g/kg did not manifest any toxicological signs in rats. The extract promoted ulcer protection as ascertained by a significant reduction of the ulcer area. Furthermore, it exhibited a significant protection activity against gastric mucosal injury by preventing the depletion of antioxidant enzymes. The level of MDA was also limited in rat stomach tissues when compared with the ulcer control group. Immunohistochemistry showed upregulation of HSP70 protein and downregulation of BAX protein in rats pretreated with the extract. The aqueous extract of H. erinaceus protected gastric mucosa in our in vivo model. It is speculated that the bioactive compounds present in the extract may play a major role in gastroprotective activity.

Full Text Available The common feed contaminant deoxynivalenol (DON was reported to influence the morphology of the pars nonglandularis (PN of porcine stomach. Moreover, finely ground feed is known to trigger the development of ulcers and other pathologies of PN while coarsely ground feed protects from such lesions. The interactions between grinding fineness and DON contamination of feed were not examined so far. Therefore, both finely and coarsely ground feeds were tested either in the absence or presence of a DON contaminated wheat on growth performance and health of rearing piglets, including stomach integrity. DON contamination significantly reduced feed intake and serum albumin concentration with this effect being more pronounced after feeding the coarsely ground feed. Albeit at a higher level, albumin concentration was also reduced after feeding the finely ground and uncontaminated feed. Finely ground and DON-contaminated feed caused a significantly more pronounced lymphoplasmacytic infiltration both of PN and pars glandularis, partly paralleled by lymph follicle formation and detritus filled foveolae and tubes suggesting a local immune response probably triggered by epithelial lesions. It is concluded that DON contamination of feed exacerbates the adverse effects of finely ground feed on stomach mucosal integrity.

Selye's general adaptation syndrome: stress-induced gastro-duodenal ulceration and inflammatory bowel disease.

Science.gov (United States)

Fink, George

2017-03-01

Hans Selye in a note to Nature in 1936 initiated the field of stress research by showing that rats exposed to nocuous stimuli responded by way of a 'general adaptation syndrome' (GAS). One of the main features of the GAS was the 'formation of acute erosions in the digestive tract, particularly in the stomach, small intestine and appendix'. This provided experimental evidence for the view based on clinical data that gastro-duodenal (peptic) ulcers could be caused by stress. This hypothesis was challenged by Marshall and Warren's Nobel Prize (2005)-winning discovery of a causal association between Helicobacter pylori and peptic ulcers. However, clinical and experimental studies suggest that stress can cause peptic ulceration in the absence of H. pylori Predictably, the etiological pendulum of gastric and duodenal ulceration has swung from 'all stress' to 'all bacteria' followed by a sober realization that both factors play a role, separately as well as together. This raises the question as to whether stress and H. pylori interact, and if so, how? Stress has also been implicated in inflammatory bowel disease (IBD) and related disorders; however, there is no proof yet that stress is the primary etiological trigger for IBD. Central dopamine mechanisms seem to be involved in the stress induction of peptic ulceration, whereas activation of the sympathetic nervous system and central and peripheral corticotrophin-releasing factor appears to mediate stress-induced IBD. © 2017 Society for Endocrinology.

Zinc salt enhances gastroprotective activity of risperidone in indomethacin-induced gastric ulcer.

Science.gov (United States)

Oluwole, F S; Onwuchekwa, C

2016-09-01

Zinc has been reported to mediate cellular responses to injury by producing cytoprotection via the scavenging of reactive oxygen species. Anti-stress medications are generally anti-psychotic drugs and anti- depressants. Some Anti-psychotic drugs such as risperidone have been reported to possess anti-ulcer activity. Risperidone as an antipsychotic drug blocks several neurotransmitter systems including dopaminergic, adrenergic, histaminergic and serotonergic pathways. The study investigated the antiulcer activity of Zinc Chloride (ZnCl(2)) in combination with risperidone in male Wistar rats. The animals were divided into two groups of twenty animals each for ZnCl(2) and risperidone groups. Each group was further divided into four subgroups. ZnCl(2) was administered orally at 20mg/kg, 40mg/kg and 80mg/kg to a subgroup, while 80mg/kg of ZnCl(2) was administered in combination with risperidone (0.1mg/kg, 0.3mg/kg and 0.5mg/kg) orally once daily for 21 days. The controls were treated with distilled water. Ulcer was induced using indomethacin. Histology of the stomach tissues was prepared with PAS and H& E stains. Ulcer score and ulcer area were assessed using standard methods. Data were analysed using student t-test and Graphpad Prism 5. There were decreases in ulcer scores using the different doses of ZnCl, (20mg/kg, 40mg/kg and 80mg/kg). Also using the highest dose ZnCl(2) (80mg/ kg) and different doses of risperidone there were decreases in ulcer scores compared to the control. This effect of the risperidone showed a significant dose- dependent reduction. The effect ZnCl(2), and risperidone were also reflected in the ulcer area and in the histology. These findings suggest that ZnCl(2), enhances the gastroprotective activity ofrisperidone in indomethacin- induced gastric ulcer. However, more detailed studies are necessary to confirm the relevance of this finding and its implications in clinical settings.

Hormonal fluctuations are known to predispose ulceration of the upper gastrointestinal tract, but to date no comparative study of their effects on the healing of pre-existing ulcers in the oral cavity and stomach has been made. We studied the effects of depletion of testosterone and of EGF on the healing of acetic acid-induced ulcers using rats having undergone bilateral orchidectomy and/or salivectomy respectively. We measured alterations in gastric acid secretion and blood flow at ulcer margins, as well as plasma levels of testosterone, gastrin and the proinflammatory cytokines IL-1 beta and TNF-alpha. Testosterone (0.01-10 mg/kg/day i. m.) dose-dependently delayed oral and gastric ulcer healing. When applied in an optimal dose of 1 mg/kg/day, this hormone significantly raised gastric acid secretion and plasma IL-1 beta and TNF-alpha levels. Attenuation of plasma testosterone levels via bilateral orchidectomy inhibited gastric acid secretion and accelerated the healing of oral and gastric ulcers, while increasing plasma gastrin levels and these effects were reversed by testosterone. Salivectomy raised plasma testosterone levels, and delayed oral and gastric ulcer healing. Treatment of salivectomised animals with testosterone further inhibited ulcer healing, and this effect was counteracted by EGF. We propose that testosterone delays ulcer healing via a fall in blood flow at the ulcer margin, a rise in plasma levels of IL-1 beta and TNF-alpha and, in the case of gastric ulcers, an increase in gastric acid secretion. EGF released from the salivary glands plays an important role in limitation of the deleterious effects of testosterone on ulcer healing.

To determine the healing effect of Teucrium polium (T. polium) in indomethacin-induced gastric ulcer in rats. In the fall of 2007, 250 Sprague-Dawley rats provided by the Shiraz University Laboratory Animal Center were divided into 4 equal groups including control (70 rats), and 3 experimental groups (60 rats each), and each group received different doses of T. polium. Ten rats were used to study the induction of gastric ulcer by indomethacin (25 mg/kg/stat). After 24 hours, their stomachs were evaluated for any mucosal ulcer. The T. polium extract was administered orally, 24 hours after indomethacin administration. In the experimental group, 10 animals were sacrificed after 24, 48, and 72 hours, after administration of T. polium, and at one, 2, and 4 weeks, and in the control group identically after the administration of distilled water. In rats treated with indomethacin, multiple ulcers were evident. After 4 weeks of treatment with T. polium, more re-epithelialization, proliferation, mucosal hyperplasia, migration of the gastric epithelial cells, and decrease in inflammatory cells were observed. The T. polium reduced the ulcer indices by >50% after one week, >80% after 2 weeks, and >90% after 4 weeks. The healing effect of T. polium may be due to antioxidant activity along with the ability to modulate the mucin secretion, prostaglandin synthesis, and epidermal growth factor receptor expression. These results along with the non-toxicity properties of T. polium suggests it as a promising anti-ulcer compound. (author)

Perforations of the stomach and duodenum are common complications of peptic ulcer disease (PUD), abuse of non steroidal anti inflammatory drugs (NSAIDS) and gastric cancer. Being a life threatening complication of PUD, it needs special attention with prompt resuscitation and appropriate surgical management if morbidity and mortality are to be avoided. To determine the pattern and management outcome of perforated peptic ulcer disease PUD as seen in University of Port Harcourt Teaching Hospital (UPTH), Port Harcourt, Rivers State, Nigeria). All the patients with perforated PUD that were managed at UPTH between January 2006 and December 2014 were studied. Relevant data were extracted from the case notes and analysed using the Statistical Package for Social Sciences (SPSS) version 17. Thirty six patients with perforated PUD were evaluated consisting of 28 males and 8 females with a male to female ratio of 3.5:1. Their ages ranged from 24 to 65 years with a mean of 42.1± 12.3 years and the peak age was at the third decade. After adequate resuscitation, all the patients had exploratory laparotomy. In 26 (72.2%) patients, the perforation was in the duodenum while in 10 (27.8%), it was in the stomach. Thirty two (88.9%) patients had Graham's omental patch repair of the perforation while simple closure only was done in 4 (11.1%) patients. Surgical site infection was the commonest post operative complication which was seen in 7 (19.4%) patients while 4 patients died giving a mortality rate of 11.1%. Perforated peptic ulcer predominantly affected young males and Graham's omental patch followed by Helicobacter pylori eradication was an effective treatment modality.

Periodontal disease has been associated with higher circulating levels of inflammatory markers and conditions associated with chronic inflammation, including vascular disease, diabetes mellitus, and cancer. Limited data exist on the relationship between periodontal disease and gastric and duodenal ulcer. We conducted a prospective cohort study of 49,120 men in the Health Professionals Follow-up Study, aged 40-75 years at enrollment in 1986. Biennially, we assessed periodontal disease, tooth loss, and other risk factors for gastric and duodenal ulcer. We validated diagnoses of gastric and duodenal ulcer through medical record review. We used Cox proportional hazards modeling, adjusting for potential confounders, to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). We documented 138 cases of gastric ulcer and 124 cases of duodenal ulcer with available information on Helicobacter pylori status over 24 years of follow-up. After adjustment for risk factors, including smoking and regular use of aspirin and non-steroidal anti-inflammatory drugs, men with periodontal disease with bone loss had a multivariate HR of ulcer of 1.62 (95% CI, 1.24-2.12). Periodontal disease appeared to be associated with a similar risk of developing ulcers that were H. pylori negative (HR 1.75; 95% CI, 1.26-2.43) than H. pylori positive (HR 1.40; 95% CI, 0.87-2.24), as well as ulcers in the stomach (HR 1.75; 95% CI, 1.21-2.53) than ulcers in the duodenum (HR 1.47; 95% CI, 0.98-2.19). Periodontal disease is associated with an increased risk of incident gastric and duodenal ulcer. This relationship may be mediated by alterations in the oral and gastrointestinal microbiome and/or systemic inflammatory factors.

Scintigraphy with Ga-67 citrate routinely performed which showed an uptake in the stomach was reviewed retrospectively. There were 24 cases correlated ; 7 cases with malignant lymphoma in the stomach, 4 with gastric carcinoma, 2 with gastritis, 1 with abscess after gastroenterostomy and 8 with no disease detected. The Ga-uptake in the stomach in those was patterned to 4 groups. Rod and wall patterns were unlikely in malignant diseases of the stomach. On the other hand, focal or irregular uptake was commonly seen in malignant diseases of the stomach. Those Ga-uptake patterns may be useful to interprete complicated distribution of the radiogallium in the G.I. tracts of the left upper abdomen.

Stomach development, stem cells and disease

Kim, Tae-Hee; Shivdasani, Ramesh A.

The stomach, an organ derived from foregut endoderm, secretes acid and enzymes and plays a key role in digestion. During development, mesenchymal-epithelial interactions drive stomach specification, patterning, differentiation and growth through selected signaling pathways and transcription factors. After birth, the gastric epithelium is maintained by the activity of stem cells. Developmental signals are aberrantly activated and stem cell functions are disrupted in gastric cancer and other disorders. Therefore, a better understanding of stomach development and stem cells can inform approaches to treating these conditions. This Review highlights the molecular mechanisms of stomach development and discusses recent findings regarding stomach stem cells and organoid cultures, and their roles in investigating disease mechanisms.

Full Text Available Abdominal Tuberculosis (TB most commonly affects ileo-caecal region. Isolated stomach involvement by TB, without pulmonary infection is rare. Clinical presentation of Stomach TB may be non-specific, radiological findings non-contributory and superficial endoscopic biopsies may not be able to settle the diagnosis. Many cases are diagnosed only after histopathological examination of surgical specimens. High degree of suspicion is needed for early diagnosis of gastric tuberculosis, if unnecessary surgical interventions are to be avoided. A young patient who was being treated as a case of chronic peptic ulcer for one year was referred for treatment of gastric outlet obstruction. Histopathological examination of gastrectomy specimen of the patient showed multiple caseating granulomas characteristic of tuberculosis and presence of acid-fast bacilli on Fite-Faraco staining, with no evidence of tuberculosis at pulmonary or other body sites. This case of isolated gastric TB is reported for its rarity.

AIM: To study the effects of amphetamine, an indirectacting adrenomimetic compound on the indomethacininduced gastric ulcerations in rats.METHODS: Male Wistar-Bratislava rats were randomly divided into four groups: Group 1 (control), received an ulcerogenic dose of indomethacin (50 μmol/kg) and Groups 2, 3 and 4, treated with amphetamine (10, 25and 50 μmol/kg). The drug was administered simultaneously with indomethacin and once again 4 h later.The animals were sacrificed 8 h after indomethacin treatment. The stomachs were opened and the incidence, the number of lesions and their severity were evaluated. The results were expressed as percentage and as mean ± standard error (mean ± SE).RESULTS: The incidence of ulceration in the control group was 100%. Amphetamine, at doses of 10, 25 and 50 μmol/kg, lowered the incidence to 88.89%, 77.78%and 37.5% respectively. The protection ratio was positive: 24.14%, 55.17% and 80.6% respectively. The total number of ulcerations/rat was 12.44 ± 3.69 in the control group. It decreased to 7.33 ± 1.89, 5.33 ± 2.38 and 2.25 ± 1.97 under the effects of the above-mentioned doses of amphetamine.CONCLUSION: Amphetamine affords a significant dose-dependent protection against the indomethacininduced gastric ulcerations in rats. It is suggested that the adrenergic system is involved in the gastric mucosa protection.

Full Text Available Human stomach is the only known natural habitat of Helicobacter pylori (Hp, a major bacterial pathogen that causes different gastroduodenal diseases. Despite this, the impact of Hp on the diversity and the composition of the gastric microbiota has been poorly studied. In this study, we have analyzed the culturable gastric microbiota of 215 Malaysian patients, including 131 Hp positive and 84 Hp negative individuals that were affected by different gastric diseases. Non-Hp bacteria isolated from biopsy samples were identified by matrix assisted laser desorption ionization-time of flight mass spectrometry based biotyping and 16SrRNA sequencing. The presence of Hp did not significantly modify the diversity of the gastric microbiota. However, correlation was observed between the isolation of Streptococci and peptic ulcer disease. In addition, as a first report, Burkholderia pseudomallei was also isolated from the gastric samples of the local population. This study suggested that there may be geographical variations in the diversity of the human gastric microbiome. Geographically linked diversity in the gastric microbiome and possible interactions between Hp and other bacterial species from stomach microbiota in pathogenesis are proposed for further investigations.

To clarify the differences in characteristics between participants and non-participants in the screening program for stomach cancer, life-style and medical histories were compared among 20, 169 subjects who lived in an urban area (Sendai) and a rural area (Wakuya and Tajiri) in Miyagi Prefecture, Japan. All subjects were classified into three groups according to the frequency of participation in the screening program during the last 5 years; i.e., frequent participating group (FPG) for 4 or 5 times, reference group (RG) for 1-3 times and non-participating group (NPG) for 0 times. Subjects in the FPG consumed more milk and green-yellow vegetable whereas those in the NPG consumed less these foods. The age-adjusted proportions of present smokers were higher in the NPG but lower in the FPG significantly. The proportions of subjects who had parental histories of all cancers and stomach cancer and past history of gastro-duodenal ulcer were higher in the FPG and lower in the NPG. To control influences among the variables a stepwise multiple regression analysis was done, and it revealed that smoking and parental history of cancers were strong predictors to explain the frequency of participation.

Purpose. To explore the effects of SiJunZiTang (SJZT) on central neurotransmitters and the inhibition of HCl hypersecretion, along with the role of the vagus nerve. From this, the effects of SJZT and its constituent ingredients on inhibiting stress-induced peptic ulcers will be determined. Methods. Methods used to determine SJZT's effectiveness included (1) measuring the antipeptic ulcer effects of varying combinations of the constituents of SJZT; (2) evaluations of monoamine (MA) level in the brain; and (3) measuring the effects of longer-term SJZT treatment. Results. Comparing the control and experimental groups where the rats' vagus nerves were not cut after taking SJZT orally (500 mg/kg and 1000 mg/kg), the volume of enterogastric juice, free HCl and total acidity all reduce dose-dependently. The group administered SJZT at 1000 mg/kg showed significant reductions (P cure rate of 34.53%. Conclusion. The results display a correlation between the therapeutic effects of SJZT on stress-induced peptic ulcers and central neurotransmitter levels. Further to this, SJZT can inhibit the hypersecretion of HCl in the stomach, thus inhibiting stress-induced peptic ulcers.

Refractory peptic ulcers are ulcers in the stomach or duodenum that do not heal after eight to 12 weeks of medical treatment or those that are associated with complications despite medical treatment. Recurrent peptic ulcers are peptic ulcers that recur after healing of the ulcer. Given the number of deaths due to peptic ulcer-related complications and the long-term complications of medical treatment (increased incidence of fracture), it is unclear whether medical or surgical intervention is the better treatment option in people with recurrent or refractory peptic ulcers. To assess the benefits and harms of medical versus surgical treatment for people with recurrent or refractory peptic ulcer. We searched the specialised register of the Cochrane Upper GI and Pancreatic Diseases group, the Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library, MEDLINE, EMBASE, Science Citation Index Expanded, and trials registers until September 2015 to identify randomised trials and non-randomised studies, using search strategies. We also searched the references of included studies to identify further studies. We considered randomised controlled trials and non-randomised studies comparing medical treatment with surgical treatment in people with refractory or recurrent peptic ulcer, irrespective of language, blinding, or publication status for inclusion in the review. Two review authors independently identified trials and extracted data. We planned to calculate the risk ratio, mean difference, standardised mean difference, or hazard ratio with 95% confidence intervals using both fixed-effect and random-effects models with Review Manager 5 based on intention-to-treat analysis. We included only one non-randomised study published 30 years ago in the review. This study included 77 participants who had gastric ulcer and in whom medical therapy (histamine H2 receptor blockers, antacids, and diet) had failed after an average duration of treatment of 29 months.

Advances in Endoscopic submucosal dissection (ESD) technology have established ESD for early gastric cancer as a safe and stable technique. However, ESD may induce delayed gastric emptying and the cause of food residue retention in the stomach after ESD is not clear. This study aimed to clarify risk factors for delayed gastric emptying with food retention after gastric ESD. We retrospectively examined for food residue in the stomach 1 week after ESD was performed for early gastric carcinoma at Osaka Saiseikai Nakatsu Hospital from February 2008 to November 2016. Food residue was observed in 68 (6.1%) of 1114 patients who underwent gastric ESD. The percentage of lesions located on the lesser curvature of the upper third of the stomach was 45.6% (31/68) in the food residue group and 3.5% (37/1046) in the non-food residue group, which was significantly different (P gastric ESD. Of the 68 patients, 3 had food residue in the stomach on endoscopic examination for follow-up observation after the ESD ulcer had healed. Delayed gastric emptying with food retention after gastric ESD was associated with lesions located in the lesser curvature of the upper stomach, submucosal invasion of the lesion, age older than 80 years, and post-ESD bleeding, though it was temporary in most cases.

The most significant feature of early carcinoma, be defined as the gastric carcinoma confined in mucosa and submucosal regardless of its size and shape, is its excellent prognosis; 5 year survival rate after operation in early stomach carcinoma amounts to 93 percent in comparison with around 25 percent in advanced carcinoma, and so the detection of this early stomach carcinoma is most important subject to minimize the mortality from stomach carcinoma at the present time. For the diagnosis of the early stomach carcinoma the radiographic study, cytology and gastroscopic examination are practised, and of those the radiographic study has been revealed commonly best results, but by usual method of upper G-I study it is often difficult to diagnose accurately. Therefore, we have been employed the barium and air double contrast method by insertion of the gastric tube. This method is simple and by this method, the adequate amount of air may introduced into the stomach for the best visualization of the mucosal pattern and gastric juice may also aspirated in a case of which the stomach wall could not be coated by barium because of excessive gastric juice. Summary of the results of this studies of early carcinoma detection at the department of radiology, Severance Hospital during 6 months since May 1969 are as followings; of 1407 cases taken upper G-I study with double contrast method, 17 cases were diagnosed as possible early stomach carcinoma radiographically, and then only 6 cases had surgical resection of stomach. Of these 2 cases were confirmed pathologically and one was considered as precancerots lesion.

2014-01-01

Probiotic lactic acid bacteria are being proposed to cure peptic ulcers by reducing colonization of Helicobacter pylori within the stomach mucosa and by eradicating already established infection. In lieu of that, in vitro inhibitory activity of pediocin-producing probiotic Pediococcus acidilactici BA28 was evaluated against H. pylori by growth inhibition assays. Further, chronic gastritis was first induced in two groups of C57BL/6 mice by orogastric inoculation with H. pylori with polyethylene catheter, and probiotic P. acidilactici BA28 was orally administered to study the eradication and cure of peptic ulcer disease. H. pylori and P. acidilactici BA28 were detected in gastric biopsy and fecal samples of mice, respectively. A probiotic treatment with P. acidilactici BA28, which is able to eliminate H. pylori infection and could reverse peptic ulcer disease, is being suggested as a co-adjustment with conventional antibiotic treatment. The study provided an evidence of controlling peptic ulcer disease, by diet mod

To compare the effects of Aloe vera and sucralfate on gastric microcirculatory changes, cytokine levels and gastric ulcer healing. Male Spraque-Dawley rats (n=48) were divided into four groups. Group1 served as control group, group 2 as gastric ulcer group without treatment, groups 3 and 4 as gastric ulcer treatment groups with sucralfate and Aloe vera. The rats from each group were divided into 2 subgroups for study of leukocyte adherence, TNF-alpha and IL-10 levels and gastric ulcer healing on days 1 and 8 after induction of gastric ulcer by 20% acetic acid. On day 1 after induction of gastric ulcer, the leukocyte adherence in postcapillary venule was significantly (P<0.05) increased in the ulcer groups when compared to the control group. The level of TNF-alpha was elevated and the level of IL-10 was reduced. In the ulcer groups treated with sucralfate and Aloe vera, leukocyte adherence was reduced in postcapillary venule. The level of IL-10 was elevated, but the level of TNF-alpha had no significant difference. On day 8, the leukocyte adherence in postcapillary venule and the level of TNF-alpha were still increased and the level of IL-10 was reduced in the ulcer group without treatment. The ulcer treated with sucralfate and Aloe vera had lower leukocyte adherence in postcapillary venule and TNF-alpha level. The level of IL-10 was still elevated compared to the ulcer group without treatment. Furthermore, histopathological examination of stomach on days 1 and 8 after induction of gastric ulcer showed that gastric tissue was damaged with inflammation. In the ulcer groups treated with sucralfate and Aloe vera on days 1 and 8, gastric inflammation was reduced, epithelial cell proliferation was enhanced and gastric glands became elongated. The ulcer sizes were also reduced compared to the ulcer group without treatment. Administration of 20% acetic acid can induce gastric inflammation, increase leukocyte adherence in postcapillary venule and TNF-alpha level and reduce

Radiolabelled antacid preparations have been monitored in the stomach using gamma scintigraphy. The stomach contents were labelled with technetium-99m and two antacid preparations with indium-113m. It has been shown that the antacid containing aluminium hydroxide and magnesium oxide mixed and emptied with the other stomach contents. An alginate containing preparation tended to float on the food and emptied only slowly from the stomach. (Auth.)

Mucosa-associated lymphoid tissue (MALT lymphoma of the stomach: features of pathomorphological diagnostics

Directory of Open Access Journals (Sweden)

2013-04-01

Full Text Available On the base of our own observations and literature data it was determined that the distinctive pathologic features of MALT-lymphoma of the stomach are the presence of a dense diffuse lymphocytic infiltrate of centrocyte-like tumor cells of marginal zone (small cells resembling centrocytes with distinct bright rim of cytoplasm, with small nuclei of irregular shape, sometimes – split, containing coarse chromatin and indistinct nucleoli in the lamina propria between the reactive lymph follicles and glands of the mucous membrane, monocytoid B-lymphocytes characterized by clear cell borders, broad light cytoplasm and bean-like nucleus, plasma cells, which may contain Dutcher bodies – intranuclear inclusions of immunoglobulins; single large centroblast-like or immunoblast-like cells having round-oval or slightly irregular in shape nuclei with 1-3 nucleoli, or vesicular-like round in shape nuclei with compact, centrally located nucleolus; small lymphocytes. Infiltration looks as tumorcell layers or, more rarely, fuzzy nodular cellular formations. An important diagnostic criterion is the presence of "lymphoepithelial lesions" zones of glands due to infiltration by 3 or more centrocyte-like tumor cell aggregates with glands’ basement membranes destruction. In the damaged glands epithelium edema and eosinophilia are marked, but if extensive infiltration is present among the lymphoid infiltrate there are only clusters of degenerated cells at the site of destroyed epithelium. Low-grade MALT-lymphoma is characterized by the absence of distinct macroscopic changes and the prevalence of "mature" tumor cells over the blasts in histological picture. MALT-lymphoma with signs of transformation into high-grade lymphoma is characterized macroscopically by distinct exophytic component, hyperplasia of folds with ulcerous defects up to 1-2 cm in diameter. Histologic picture displays a significant amount of blast cells – both in the infiltrate and in the areas

The oral cavity is a rare but occasional target for metastases, which may masquerade as various benign and inflammatory lesions, and sometimes also be asymptomatic. Oral metastatic lesions have been described in various cancers, particularly lung, breast and kidney carcinoma. We here describe an uncommon case of a hard palate mucosa and gingival metastasis from gastric carcinoma that was originally diagnosed as a periodontal disease. Histopathological examination of a biopsy of the lesion revealed a signet-ring cell carcinoma, and a subsequent biopsy of an ulcerated stomach lesion showed a poorly differentiated gastric carcinoma. The patient underwent gastric resection but died of heart failure on the tenth postoperative day; a post-mortem examination revealed a residual bilateral ovarian infiltration by gastric carcinoma (Krukenberg's tumor). An occult carcinoma of the stomach may rarely metastasise to the oral cavity even as a first and exclusive manifestation; it is important to bear this possibility in mind because such conditions may mimic a benign disease

The electron density resolution of synchrotron-radiation phase-contrast imaging (SR-PCI) is 1000 times higher than that of conventional X-ray absorption imaging in light elements, through which high-resolution X-ray imaging of biological soft tissue can be achieved. For biological soft tissue, SR-PCI can give better imaging contrast than conventional X-ray absorption imaging. In this study, human resected stomach and gastric cancer were investigated using in-line holography and diffraction enhanced imaging at beamline 4W1A of the Beijing Synchrotron Radiation Facility. It was possible to depict gastric pits, measuring 50-70 µm, gastric grooves and tiny blood vessels in the submucosa layer by SR-PCI. The fine structure of a cancerous ulcer was displayed clearly on imaging the mucosa. The delamination of the gastric wall and infiltration of cancer in the submucosa layer were also demonstrated on cross-sectional imaging. In conclusion, SR-PCI can demonstrate the subtle structures of stomach and gastric cancer that cannot be detected by conventional X-ray absorption imaging, which prompt the X-ray diagnosis of gastric disease to the level of the gastric pit, and has the potential to provide new methods for the imageology of gastric cancer.

To evaluate whether green tea consumption provides protection against stomach cancer death, relative risks were calculated using Cox proportional hazards regression analysis in the Japan Collaborative Study for Evaluation of Cancer Risk, sponsored by the Ministry of Health and Welfare (JACC Study). The study was based on 30 370 men and 42 481 women aged 40–79. After adjustment for age, smoking status, history of peptic ulcer, family history of stomach cancer along with certain dietary items, the risks associated with drinking one or two, three or four, five to nine, and 10 or more cups of green tea per day, relative to those of drinking less than one cup per day, were 1.6 (95% CI: 0.9–2.9), 1.1 (95% CI: 0.6–1.9), 1.0 (95% CI: 0.5–2.0), and 1.0 (95% CI: 0.5–2.0), respectively, in men (P for trend=0.669), and 1.1 (95% CI: 0.5–2.5), 1.0 (95% CI: 0.5–2.5), 0.8 (95% CI: 0.4–1.6), and 0.8 (95% CI: 0.3–2.1), respectively, in women (P for trend=0.488). We found no inverse association between green tea consumption and the risk of stomach cancer death.

Full Text Available The healing activity of gallic acid enriched ethanolic extract (GAE of Phyllanthus emblica fruits (amla against the indomethacin-induced gastric ulceration in mice was investigated. The activity was correlated with the ability of GAE to alter the cyclooxygenase- (COX- dependent healing pathways. Histology of the stomach tissues revealed maximum ulceration on the 3rd day after indomethacin (18 mg/kg, single dose administration that was associated with significant increase in inflammatory factors, namely, mucosal myeloperoxidase (MPO activity and inducible nitric oxide synthase (i-NOS expression. Proangiogenic parameters such as the levels of prostaglandin (PG E2, vascular endothelial growth factor (VEGF, hepatocyte growth factor (HGF, von Willebrand Factor VIII, and endothelial NOS (e-NOS were downregulated by indomethacin. Treatment with GAE (5 mg/kg/day and omeprazole (3 mg/kg/day for 3 days led to effective healing of the acute ulceration, while GAE could reverse the indomethacin-induced proinflammatory changes of the designated biochemical parameters. The ulcer healing activity of GAE was, however, compromised by coadministration of the nonspecific NOS inhibitor, N-nitro-L-arginine methyl ester (L-NAME, but not the i-NOS-specific inhibitor, L-N6-(1-iminoethyl lysine hydrochloride (L-NIL. Taken together, these results suggested that the GAE treatment accelerates ulcer healing by inducing PGE2 synthesis and augmenting e-NOS/i-NOS ratio.

Present-day potentialities of radiodiagnosis of stomach cancer were studied using the results of clinicoradiological examination of 209 patients, mainly with endophytic and small forms of stomach cancer and 28 with stomach polypus. It was shown that to achieve the most complete and objective estimation of tumor changes in the stomach a combination of X-ray methods including routine examination with barium suspension and double contrast should be used. One of the most promising trends in radiodiagnosis of stomach cancer is fluorographic mass screening for stomach cancer in persons at high risk with subsequent selective endoscopic examination ( according to indications ). Double contrast remains the major and most informative part of standardized technique of gastrofluorographic examination

Successful pluripotent stem cell differentiation methods have been developed for several endoderm-derived cells, including hepatocytes, β-cells and intestinal cells. However, stomach lineage commitment from pluripotent stem cells has remained a challenge, and only antrum specification has been demonstrated. We established a method for stomach differentiation from embryonic stem cells by inducing mesenchymal Barx1, an essential gene for in vivo stomach specification from gut endoderm. Barx1-inducing culture conditions generated stomach primordium-like spheroids, which differentiated into mature stomach tissue cells in both the corpus and antrum by three-dimensional culture. This embryonic stem cell-derived stomach tissue (e-ST) shared a similar gene expression profile with adult stomach, and secreted pepsinogen as well as gastric acid. Furthermore, TGFA overexpression in e-ST caused hypertrophic mucus and gastric anacidity, which mimicked Ménétrier disease in vitro. Thus, in vitro stomach tissue derived from pluripotent stem cells mimics in vivo development and can be used for stomach disease models.

The aim of this study was to develop nanoparticles for oral delivery of an acid-labile drug, lansoprazole (LPZ), for gastric ulcer therapy. LPZ-loaded positively charged Eudragit(®) RS100 nanoparticles (ERSNPs-LPZ) and negatively charged poly(lactic-co-glycolic acid) nanoparticles (PLGANPs-LPZ) were prepared. The effect of charge on nanoparticle deposition in ulcerated and non-ulcerated regions of the stomach was investigated. The cellular uptake of nanoparticles in the intestine was evaluated in a Caco-2 cell model. The pharmacokinetic performance and ulcer healing response of LPZ-loaded nanoparticles following oral administration were evaluated in Wistar rats with induced ulcers. The prepared drug-loaded ERSNPs-LPZ and PLGANPs-LPZ possessed opposite surface charge (+38.5±0.3 mV versus -27.3±0.3 mV, respectively) and the particle size was around 200 nm with a narrow size distribution. The negatively charged PLGANPs adhered more readily to the ulcerated region (7.22%±1.21% per cm(2)), whereas the positively charged ERSNPs preferentially distributed in the non-ulcerated region (8.29%±0.35% per cm(2)). Both ERSNPs and PLGANPs were prominent uptake in Caco-2 cells, too. The nanoparticles sustained and prolonged LPZ concentrations up to 24 hours, and the half-life and mean residence time of LPZ were prolonged by 3.5-fold and 4.5-fold, respectively, as compared with LPZ solution. Oral administration of LPZ-loaded nanoparticles healed 92.6%-95.7% of gastric ulcers in Wistar rats within 7 days.

Glycyrrhiza is the dry root and rhizome of the leguminous plant, Glycyrrhiza uralensis Fisch., Glycyrrhiza inflata Bat. or Glycyrrhiza glabra L., which was firstly cited in Shennong's Herbal Classic in Han dynasty and was officially listed in the Chinese Pharmacopoeia, has been widely used in China during the past millennia. Licoflavone is the major component of Glycyrrhiza with anti-ulcer activity. The present study is based on clarifying the anti-ulcer effect of licoflavone, aiming at elucidating the possible molecule mechanisms of its action for treating gastric ulcer rats induced by acetic acid. Rats were divided into 7 groups, and drugs were administered from on the day after the onset of gastric ulcer (day 3) until day 11 of the experiment once daily continuously. The plasma were analyzed by high-performance liquid chromatography combined with time-of-flight mass spectrometry (HPLC/ESI-TOF-MS), significant different metabolites were investigated to explain its therapeutic mechanism. Furthermore, quantitative real time polymerase chain reaction (RT-PCR) analysis was performed to detect the expression of RNA in stomach tissue for verifying the above results. Licoflavone can effectively cure the gastric ulcer, particularly the middle dose group. According to the statistical analysis of the plasma different metabolites from each groups and the expression of genes in tissues, sixteen significant different metabolites, including histamine, tryptophan, arachidonic acid, phingosine-1-phosphate etc., contributing to the treatment of gastric ulcer were discovered and identified. In RT-PCR analysis, the results of the expression of RNA were corresponded with what we discovered. Our study indicated licoflavone plays the role of treating gastric ulcer by regulating inflammation mediators and amino acid metabolism. We demonstrated that metabolomics technology combined with gene technology is a useful tool to search different metabolites and to dissect the potential

CT is a valuable method for preoperative staging of patients with stomach cancers. However, in patients with poor distension of the stomach and scanty fat between the stomach and adjacent organs, CT findings may indicate a false impression of gastric wall thickening and cannot provide the precise extent of stomach cancer. We studied the usefulness of gastric distension by gas-forming agent in 28 cases of pathologically confirmed gastric cancers on CT. Comparative analysis between CT findings and surgical pathologic findings was done in 22 cases who underwent surgery. The results were as follows; 1. Conventional CT failed to define the wall thickening or masses of the stomach, in 14 cases of 23 advanced gastric cancers, while CT with gas distension technique allowed good visualization in all advanced gastric cancers. 2. In 2 cases of 5 early gastric cancers, CT with gas distension technique could detect focal thickening of the gastric wall, even less than 1cm thickness. 3. Among 13 cases with indistinguishable border between stomach and liver on conventional CT, 7 cases were diagnosed as negative invasion on CT with gas distension technique and 5 cases of these were confirmed by surgery. 4. Among 11 cases with indistinguishable border between stomach and pancreas on conventional CT, 3 cases were diagnosed as negative invasion on CT with gas distension technique, all of which were confirmed by surgery. 5. There was no significant difference between conventional CT and CT with gas distension technique of the stomach to diagnose invasion into transverse colon, transverse colon, transverse mesocolon, lymph node metastasis, and various distant metastasis.

A case of a gastric cancer which developed 3 years and 11 months after radiotherapy for esophageal cancer is reported. A 76-year-old man with a squamous cell carcinoma of the lower intrathoracic esophagus had received 50 Gy of irradiation as treatment. Thereafter, signs of the esophageal cancer disappeared radiologically and endoscopically, and a pathological biopsy of secimens taken from the site revealed no futher cancer cells. The patient remained well for 3 years and 11 months after radiotherapy, at which time he again was admitted to hospital, having been diagnosed as having a gastric cancer. On admission, an upper G-I series showed a shadow defect along the lesser curvature of the upper-middle stomach but no evidence of any stenosis in the lower intrathoracic esophagus. Endoscopically, the mucosal surface of the esophagus was normal, and biopsy specimens taken from the site in the esophagus that had been treated with irradiation 3 years 11 months ago revealed no recurrence of his esophageal cancer. Endoscopical examination of the stomach showed an infiltrative tumor with ulceration, and a subsequent histological examination revealed a poorly differentiated adenocarcinoma. Upon a laparotomy, a metastasis was detected in the perigastric and paraaortic lymphnodes and the cancer had invaded the retroperitoneum. The stomach could not be removed and he died 3 months after the laparotomy. (author)

Sonographic demonstration of stomach pathology: Reviewing the cases

Science.gov (United States)

2015-01-01

Abstract Introduction: The stomach can be the source of complaints for many patients attending for upper abdominal ultrasound. It is not routinely imaged as part of most upper abdominal ultrasound protocols, with sonographers and sonologists alike commonly muttering the line; “I can't see the stomach on ultrasound”. However, this is incorrect, as the gastric antrum can almost always be visualised sonographically. Discussion: It is possible to detect a range of pathologies affecting the stomach sonographically, from common, largely tolerable conditions such as hiatus hernias through to life‐threatening neoplasms. Conclusion: The stomach can easily be assessed during routine abdominal ultrasound providing the sonographer has knowledge of stomach anatomy, normal ultrasound appearances and limitations to its visualisation. While endoscopy is the gold standard for investigation of the stomach and upper gastrointestinal tract, many patients will initially present for abdominal ultrasound due to its easy, non‐invasive nature, ready availability and low cost. For patients with mild abdominal symptoms, a normal abdominal ultrasound may be the extent of their imaging investigations meaning stomach pathologies may go undiagnosed. PMID:28191199

Solitary fibrous tumors are spindle-cell neoplasms that usually develop in the pleura and peritoneum, and rarely arise in the stomach. To our knowledge, there is only one case reporting a solitary fibrous tumor arising from stomach in the English literature. Here we report the case of a 26-year-old man with a large solitary fibrous tumor arising from the stomach which involved the submucosa and muscular layer and resembled a gastrointestinal stromal tumor in the stomach, based on what was seen during abdominal computed tomography. A solitary fibrous tumor arising from the stomach, although rare, could be considered as a diagnostic possibility for gastric submucosal tumors. PMID:18159603

Aim: Since there is an increasing need for gastric ulcer therapies with optimum benefit-risk profile. This study was conducted to investigate gastro-protective effects of N-Acetylcysteine (NAC against ethanol-induced gastric ulcer models in mice. Materials and Methods: Forty-two mice were allocated into six groups consisting of 7 mice each. Groups 1 (normal control and 2 (ulcer control received distilled water at a dose of 10 ml/kg, groups 3, 4 and 5 were given NAC at doses 100, 300 and 500 mg/kg, respectively, and the 6th group received ranitidine (50 mg/kg. All drugs administered orally once daily for 7 days, on the 8th day absolute ethanol (7 ml/kg was administrated orally to all mice to induce the acute ulcer except normal control group. Then 3 h after, all animals were sacrificed then consequently the stomachs were excised for examination. Results: NAC administration at the tested doses showed a dose-related potent gastro-protective effect with significant increase in curative ratio, PH of gastric juice and mucus content viscosity seen with the highest dose of NAC and it is comparable with that observed in ranitidine group. Conclusion: The present findings demonstrate that, oral NAC shows significant gastro-protective effects comparable to ranitidine confirmed by antisecretory, cytoprotective, histological and biochemical data but the molecular mechanisms behind such protection are complex.

Purpose Treatment-related stomach cancer is an important cause of morbidity and mortality among the growing number of Hodgkin lymphoma (HL) survivors, but risks associated with specific HL treatments are unclear. Patients and Methods We conducted an international case-control study of stomach cancer nested in a cohort of 19,882 HL survivors diagnosed from 1953 to 2003, including 89 cases and 190 matched controls. For each patient, we quantified cumulative doses of specific alkylating agents (AAs) and reconstructed radiation dose to the stomach tumor location. Results Stomach cancer risk increased with increasing radiation dose to the stomach (Ptrend < .001) and with increasing number of AA-containing chemotherapy cycles (Ptrend = .02). Patients who received both radiation to the stomach ≥ 25 Gy and high-dose procarbazine (≥ 5,600 mg/m2) had strikingly elevated stomach cancer risk (25 cases, two controls; odds ratio [OR], 77.5; 95% CI, 14.7 to 1452) compared with those who received radiation < 25 Gy and procarbazine < 5,600 mg/m2 (Pinteraction < .001). Risk was also elevated (OR, 2.8; 95% CI, 1.3 to 6.4) among patients who received radiation to the stomach ≥ 25 Gy but procarbazine < 5,600 mg/m2; however, no procarbazine-related risk was evident with radiation < 25 Gy. Treatment with dacarbazine also increased stomach cancer risk (12 cases, nine controls; OR, 8.8; 95% CI, 2.1 to 46.6), after adjustment for radiation and procarbazine doses. Conclusion Patients with HL who received subdiaphragmatic radiotherapy had dose-dependent increased risk of stomach cancer, with marked risks for patients who also received chemotherapy containing high-dose procarbazine. For current patients, risks and benefits of exposure to both procarbazine and subdiaphragmatic radiotherapy should be weighed carefully. For patients treated previously, GI symptoms should be evaluated promptly. PMID:23980092

2005-09-01

Full Text Available Abstract Background The oral cavity is a rare but occasional target for metastases, which may masquerade as various benign and inflammatory lesions, and sometimes also be asymptomatic. Oral metastatic lesions have been described in various cancers, particularly lung, breast and kidney carcinoma. Case presentation We here describe an uncommon case of a hard palate mucosa and gingival metastasis from gastric carcinoma that was originally diagnosed as a periodontal disease. Histopathological examination of a biopsy of the lesion revealed a signet-ring cell carcinoma, and a subsequent biopsy of an ulcerated stomach lesion showed a poorly differentiated gastric carcinoma. The patient underwent gastric resection but died of heart failure on the tenth postoperative day; a post-mortem examination revealed a residual bilateral ovarian infiltration by gastric carcinoma (Krukenberg's tumor. Conclusion An occult carcinoma of the stomach may rarely metastasise to the oral cavity even as a first and exclusive manifestation; it is important to bear this possibility in mind because such conditions may mimic a benign disease.

Evodiamine (EVD), a major alkaloid compound extracted from the dry unripened fruit Evodia fructus (Evodia rutaecarpa Benth., Rutaceae), has various pharmacological effects. The purpose of the present study was to investigate the possible anti-ulcerogenic potential of EVD and explore the underlying mechanism against ethanol-induced gastric ulcer in mice. Administration of EVD at the doses of 20, 40mg/kg body weight prior to the ethanol ingestion could effectively protect the stomach from ulceration. The gastric lesion was significantly ameliorated in the EVD group compared with that in the model group. Pre-treatment with EVD prevented the oxidative damage and decreased the levels of prostaglandin E2 (PGE2) content, interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α). In addition, EVD pretreatment markedly increased the serum levels of glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT), decreased malonaldehyde (MDA) content in serum and activity of myeloperoxidase (MPO) in stomach tissues compared with those in the model group. In the mechanistic study, significant elevation of Rho, Rho-kinase 1 (ROCK1), ROCK2, cytosolic and nucleic NF-κBp65 expressions were observed in the gastric mucosa group, whereas EVD effectively suppressed the protein expressions of Rho, Rho-kinase 1 (ROCK1), ROCK2, cytosolic and nucleic NF-κBp65 in mice. Moreover, EVD showed protective activity on ethanol-induced GES-1 cells, while the therapeutic effects were not due to its cytotoxity. Taken together, these results strongly indicated that EVD exerted a gastro-protective effect against gastric ulceration. The underlying mechanism might be associated with the improvement of antioxidant and anti-inflammatory status through Rho/NF-κB pathway. Copyright © 2015 Elsevier B.V. All rights reserved.

Limited data are available on the relative pharmacokinetics and pharmacodynamics of different omeprazole formulations. To compare pharmacokinetic and pharmacodynamic effects of a novel omeprazole formulation against a currently registered product. Masked 2 period, 2 treatment crossover. Twelve clinically healthy horses were studied over two 6-day treatment periods. Horses were randomly assigned to receive a novel omeprazole paste (Ulcershield: ULS) or a currently registered reference omeprazole product (OMO). Gastric pH was measured continuously for 10 h on the day prior to commencing treatment (Day -1) and after 6 days of oral treatment (Day 5) using in situ antimony pH probes within an indwelling nasogastric tube. Plasma pharmacokinetics were determined on Days 0 and 6. Treatment significantly (Pulcer severity scores (both P = 0.004), with no difference between treatments (P = 0.688). Comparison of mean log area under time-plasma concentration curves demonstrated that, although the lower limit of the 90% confidence interval was within the -20% limit for bioequivalence, the upper limit was exceeded, suggesting that the test product could have greater bioavailability than the reference product. The small sample size, large interhorse plasma omeprazole concentrations, and low bioavailability of omeprazole impacted the sensitivity of the bioequivalence analysis. ULS matched or slightly exceeded OMO plasma concentrations. Both products resulted in equivalent increases in gastric pH, gastric pH profiles and decrease in gastric ulcer scores. Thus, ULS was pharmacodynamically equivalent to OMO and was associated with an equivalent beneficial effect on gastric squamous mucosal ulceration. © 2017 EVJ Ltd.

Microbiota in the stomach: new insights.

Bacteria are sparsely distributed in the stomach due to the gastric microbicidal barrier. Several innate defenses (low pH, migrating motor complex and the entero-salivary circulation of nitrate) as well as external factors (diet, Helicobacter pylori infection, proton pump inhibitors, antibiotics and stomach diseases) have been shown to influence significantly the microbiota composition in the stomach. In recent years new culture-independent technologies have allowed the investigation of the cross talk that occurs between hosts and stomach-associated microflora, which helps us to understand the role of gastric bacterial flora in the gastrointestinal microbiological system, both in physiological and pathological conditions. Here, we reviewed the literatures related to this topic and set the stage for future developments of the field. © 2013 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

The stomach, cholecystokinin, and satiety.

Science.gov (United States)

McHugh, P R; Moran, T H

1986-04-01

The stomach of the rhesus monkey empties liquids in a fashion that varies with the character of the solutions. Physiological saline empties exponentially. Glucose solutions empty biphasically--rapidly for the first minutes, then slowly and proportionately to glucose concentration to deliver glucose calories through the pylorus at a regulated rate (0.4 kcal/min). This prolonged and regulated second phase of gastric emptying depends on intestinal inhibition of the stomach. Cholecystokinin (CCK), a hormone released by food in the intestine, is an inhibitor of gastric emptying. In vitro receptor autoradiography demonstrates CCK receptors to be clustered on the circular muscle of the pylorus. Exogenous CCK, in doses that inhibit gastric emptying, will reduce food intake only if combined with an infusion of saline in the stomach. These observations indicate how gastric distension can be a means for provoking satiety. The variably sustained distension produced by the stomach's slow, calorically regulated emptying could prolong intermeal intervals and thus permit high-calorie meals to inhibit further caloric intake over time. CCK, by directly inhibiting gastric emptying during a meal, could promote gastric distension and so restrict the duration and size of individual meals.

Primary squamous cell carcinoma of the stomach is very rare. Its pathogenesis is unclear and the treatment strategy is controversial. We report an agressive primary squamous cell carcinoma of the stomach with liver and lung metastases in a 55-year-old man. The patient presented with a 1-month history of abdominal pain, vomiting and weight loss. Abdominal ultrasound revealed multiple liver metastases. Endoscopic examination showed two tumour masses on the fundus of the stomach. Biopsy of the lesions revealed squamous cell carcinoma of the stomach. Chest x-ray showed multiple large pulmonary nodules highly suggestive of pulmonary metastases. The patient died ten days after he was admitted because of progression of the tumour and before any therapeutic decision.

BACKGROUND: Abdominal radiotherapy for testicular cancer (TC) increases risk for second stomach cancer, although data on the radiation dose-response relationship are sparse. METHODS: In a cohort of 22,269 5-year TC survivors diagnosed during 1959-1987, doses to stomach subsites were estimated...... for 92 patients who developed stomach cancer and 180 matched controls. Chemotherapy details were recorded. Odds ratios (ORs) were estimated using logistic regression. RESULTS: Cumulative incidence of second primary stomach cancer was 1.45% at 30 years after TC diagnosis. The TC survivors who received...... radiotherapy (87 (95%) cases, 151 (84%) controls) had a 5.9-fold (95% confidence interval (CI) 1.7-20.7) increased risk of stomach cancer. Risk increased with increasing stomach dose (P-trend

Around 125,785 new cases in year 2013-14 of leprosy were detected in India as per WHO report on leprosy in September 2015 which accounts to approximately 62% of the total new cases. Anaesthetic foot caused by leprosy leads to uneven loading of foot leading to ulcer in approximately 20% of the cases. Much efforts have gone in identifying newer techniques to efficiently monitor the progress of ulcer healing. Current techniques followed in measuring the size of ulcers, have not been found to be so accurate but are still is followed by clinicians across the globe. Quantification of prognosis of the condition would be required to understand the efficacy of current treatment methods and plan for further treatment. This study aims at developing a non contact technique to precisely measure the size of ulcer in patients affected by leprosy. Using MATLAB software, GUI was designed to process the acquired ulcer image by segmenting and calculating the pixel area of the image. The image was further converted to a standard measurement using a reference object. The developed technique was tested on 16 ulcer images acquired from 10 leprosy patients with plantar ulcers. Statistical analysis was done using MedCalc analysis software to find the reliability of the system. The analysis showed a very high correlation coefficient (r=0.9882) between the ulcer area measurements done using traditional technique and the newly developed technique, The reliability of the newly developed technique was significant with a significance level of 99.9%. The designed non-contact ulcer area calculating system using MATLAB is found to be a reliable system in calculating the size of ulcers. The technique would help clinicians have a reliable tool to monitor the progress of ulcer healing and help modify the treatment protocol if needed. Copyright © 2017 European Foot and Ankle Society.

2013-01-01

Full Text Available Purpose. To explore the effects of SiJunZiTang (SJZT on central neurotransmitters and the inhibition of HCl hypersecretion, along with the role of the vagus nerve. From this, the effects of SJZT and its constituent ingredients on inhibiting stress-induced peptic ulcers will be determined. Methods. Methods used to determine SJZT's effectiveness included (1 measuring the antipeptic ulcer effects of varying combinations of the constituents of SJZT; (2 evaluations of monoamine (MA level in the brain; and (3 measuring the effects of longer-term SJZT treatment. Results. Comparing the control and experimental groups where the rats’ vagus nerves were not cut after taking SJZT orally (500 mg/kg and 1000 mg/kg, the volume of enterogastric juice, free HCl and total acidity all reduce dose-dependently. The group administered SJZT at 1000 mg/kg showed significant reductions (P<0.05. For the experimental groups where the vagus nerves were cut, a comparison with the control group suggests that the group receiving SJZT (500 mg/kg orally for 21 days demonstrated a cure rate of 34.53%. Conclusion. The results display a correlation between the therapeutic effects of SJZT on stress-induced peptic ulcers and central neurotransmitter levels. Further to this, SJZT can inhibit the hypersecretion of HCl in the stomach, thus inhibiting stress-induced peptic ulcers.

The purpose of this study was to investigate the gastroprotective effects of bovine milk on an acidified ethanol (HCl-ethanol) mixture that induced gastric ulcers in a mouse model. Mice received different doses of commercial fresh bovine milk (5, 10, and 20 mL/kg of body weight) by oral gavage once a day for 14 d. One hour after the last oral administration of bovine milk, the HCl-ethanol mixture was orally intubated to provoke severe gastric damage. Our results showed that pretreatment with bovine milk significantly suppressed the formation of gastric mucosa lesions. Pretreatment lowered gastric myeloperoxidase and increased gastric mucus contents and antioxidant enzymes catalase and superoxide dismutase. Administration of bovine milk increased nitrate/nitrite levels and decreased the malondialdehyde levels and the expression of proinflammatory genes, including transcription factor nuclear factor-κB, cyclooxygenase-2, and inducible nitric oxide synthase in the stomach of mice. These results suggest that bovine milk can prevent the development of gastric ulcer caused by acid and alcohol in mice. Copyright © 2018 American Dairy Science Association. Published by Elsevier Inc.

He had anorexia without nausea and vomiting. He was tachycardic and tachypneic, but he did not have fever. On physical examination, bowel sound was hypoactive, there was generalize tenderness, guarding and rebound tender-ness focused in the right lower quadrant and suprapubic region. Laboratory finding indicated leukocytosis. Chest X-ray showed free air under diaphragm. Once the diagno-sis has been made, the patient was given analgesia and antibiotics, resuscitated with isotonic fluid, and taken to the operating room. Laparotomy was implemented through a midline incision. There was bile secretion in the peritoneal cavity. Appendix was inflamated. Cecum and ileum were normal. A small perforation, 4mm in size was detected in first portion of duodenum. Appendectomy and omental patch repair were done. Ten days later, the patient was discharged in a good state. Serologic test for helicobacter pylori was negative.Conclusion: Stomach and duodenal perforation should be considered in patients with-out peptic ulcer disease, especially in children and adolescents with sudden and severe abdominal pain who are admitted to the hospital for other diseases. Because some patients present with peptic ulcer complications that are seemingly exacerbated by stressful life events.

The study was designed to investigate the effect of trimebutine maleate, a drug used in both hyperkinetic and hypokinetic motility disorders, on gastric emptying in patients with non-ulcer dyspepsia having prolonged gastric emptying rates and to compare the parameters used for the determination of the lag period observed during the emptying of solid foods from the stomach. Gastric emptying was measured by the radionuclide technique. Twenty normal volunteers and 43 patients with non-ulcer dyspepsia participated in the study. Radionuclide imaging was performed by using a solid meal labeled with {sup 99m}Tc-tin colloid. Of the patients with non-ulcer dyspepsia, 20 had prolonged gastric emptying. They were given three weeks of oral treatment with trimebutine maleate and had their radionuclide gastric emptying study repeated. Treatment with trimebutine maleate resulted in reduction in duration of the lag period and less retention of food at 100 minutes (p<0.0005). After treatment with trimebutine maleate, no significant difference has been observed in the mean symptom score of patients with prolonged gastric emptying. Among the parameters used for the determination of the lag period, lag period determined by a mathematical equation (TLAG) has been found to be longer than the lag period determined by visual inspection of the images (VLAG) and there was correlation between the two parameters when the lag time was short.

Functional disorders of the stomach

Science.gov (United States)

Koch, K. L.; Stern, R. M.

1990-01-01

Gastroenterologists frequently encounter patients who report vague epigastric discomforts or sensations of fullness, bloating, and distention in the upper abdomen. The discomfort is neither burning in character nor severe in intensity; there is no nocturnal pain. The epigastric location of discomfort and lack of radiation may help to exclude biliary tract and pancreatic diseases. Nausea may be present, but there is little or no vomiting. After these patients ingest liquids or solid foods, the symptoms of easy filling or early satiety and increasing discomfort and nausea are almost always present. The patient may only report "indigestion," but a specific chief complaint, such as pain, discomfort, nausea, or bloating may be elicited with further inquiries. Solid foods usually provoke more symptoms than do liquids. Symptoms of early satiety, nausea, bloating, and abdominal discomfort may culminate in the vomiting of undigested food. These vague upper gastrointestinal (GI) symptoms have been termed "dyspepsia." When peptic diseases of the stomach are excluded, the symptom complex has been called "nonulcer" dyspepsia, a vague syndrome with symptoms attributed to stomach dysfunction. Nonulcer dyspepsia has been reviewed recently. Such symptoms, commonly attributed to a "functional" disorder, are very common in clinical practice, with an incidence of 30% of patients. In this review, we will discuss an approach to the evaluation and treatment of patients with symptoms of nausea, early satiety, bloating, and vague epigastric discomfort--dyspeptic symptoms associated with functional stomach disorders. We will review the anatomy and motility of the stomach and suggest potential neuromuscular malfunctions of the stomach that may result in epigastric symptoms. The potential role of stress and other brain-gut interactions, which may underlie these symptoms, will also be reviewed.

Das, Shyamal K; Roy, Chandan

2012-01-01

Gastro duodenal ulcer is a common disorder of the gastrointestinal tract. Several Indian medicinal plants have been traditionally and extensively used to prevent different diseases. In the present research studies, Bael fruit (Aegle marmelos (AM), family: Rutaceae) which are also called as Bilva in ancient Sanskrit was used as a herbal drug and its antioxidative role in aspirin- induced gastroduodenal ulceration in albino rat was evaluated using essential biochemical parameters. Mucosal thickness (MT), ulcer index (UI), different biochemical parameters, such as aspartate aminotransferase (AST), alanine aminotransferase (ALT), catalase (CAT), superoxide dismutase (SOD), reduced glutathione (GSH), and lipid peroxidation (LPO) were measured in all the groups, to study the possible involvement of antioxidants with gastroduodenal protection. A significant decrease in MT, SOD and CAT activities and GSH level and a significant increase in UI, AST, ALT, and ALP activities and LPO level were observed in aspirin treated stomach and duodenum of albino rats. Pretreatment with AM fruit pulp extract for 14 consecutive days showed the reverse effects of aspirin suggesting gastro-duodenal protective and anti- ulcerogenic properties of AM through its antioxidant mechanism.

Full Text Available This study investigated the protective effects of methanol extract of Vernonia amygdalina leaf (MEVA on aspirin induced gastric ulcer in rats. Thirty Wistar rats, 150–200 g were divided into six groups as follows: Group 1 (control rats received 2 mL/kg of propylene glycol for 28 consecutive days. Group 2 (Ulcer Control received 150 mg/kg/day of aspirin suspended in 3 mL of 1% carboxymethylcellulose in water orally for 3 consecutive days during which the rats were fasted for the induction of ulcer. Group 3 received cimetidine at 100 mg/kg/day orally for 28 consecutive days and thereafter treated as group 2. Groups 4, 5 and 6 received MEVA orally at 200, 300 and 400 mg/kg/day respectively for 28 consecutive days and thereafter were treated with aspirin as group 2. All the animals were sacrifice at the end of the study to determine the gastric pH, gastric acidity, gastric ulcer score, haematological indices, superoxide dismutase (SOD activity, reduced glutathione (GSH and Lipid peroxidation (LPO levels. The result showed that aspirin significantly (p < 0.05 increased gastric ulcer score and index, decreased gastric pH, gastric acidity, SOD activity, GSH level as well as increased LPO level. It induced significant necrosis of the stomach tissue. Administration of MEVA significantly (p < 0.05 increased gastric pH, but decreased gastric acid secretion and reversed alteration of haematological parameters. It also significantly (p < 0.05 increased SOD activity, GSH level and decreased LPO level. The results suggest that Vernonia amygdalina possesses gastro-protective properties against aspirin-induced gastric ulcer. Keywords: Vernonia amygdalina, Aspirin, Gastric ulcer, Antioxidant, Rat

Cytomegalovirus infection is an important cause of morbidity in immunosupressed patients with Human Immunodeficiency Virus (HIV). In this paper we present a 43 years old man with renal failure under hemodialysis, several blood transfusions because of anemia and three months of disease characterized by epigastric pain, specially at nights, ameliorated with antacid drugs. Other symptoms were early satisfy, vomits and weigh loss (18Kg). At clinical exam, the patient was pallid, presented adenopathies at cervical and inguinal regions and had a pain at epigastric region in profound touch palpation. The most important exams were HB: 10mg/dl, CMV: 83.5, leukocytes 7000, lymphocytes: 1715, erythrocyte sedimentation rate 49mm/h, the venon test (-), and Giardia lamblia trophozoites in stools. The studies demonstrated the patient was seropositive for HIV and the tests for IgG CMV and IgG Herpes virus resulted seropositives too. At endoscopy the esophagus mucosa was covered by a white plaque which suggests candida infection. In the stomach, over the body gastric, we found a big and deep ulcerated lesion (45 x 41mm), with defined rims and white fund. Biopsy from the edges of the gastric ulcer had the characteristic CMV intranuclear and intracytoplasmic inclusions; we confirmed the diagnosis by immunohystochemistry. The patient receives ganciclovir an then HAART and is getting well.

In patients with duodenal ulcer, mucosal blood flow of pentagastrin-stimulated stomach was studied using sup(99m)Tc-methylaminophenazone clearance technique published previously by the authors. Comparative investigations were carried out in active and inactive phases of the disease and in operated patients before and after highly selective vagotomy. The relation between gastric mucosal blood flow and acid secretion proved to be different from that of the normacid controls: in duodenal ulcer patients the secretory capacity in relation to the blood supply proved to be increased. Both the mucosal blood flow and acid secretion values were elevated in the active stage as compared to the inactive phase, while the proportion between them remained unchanged. The relation of secretion to mucosal blood flow after highly selective vagotomy became similar to that of the normal controls. It is suggested that the sup(99m)Tc-methylaminophenazone clearance method is a suitable tool to evaluate the effectiveness of vagotomy. (author)

Full Text Available Stomach diseases have an important place in the clinical pathology of dogs. Etiological factors can be nutritive, chemical, or infective, but treatment implies certain common general principles and a certain number of therapy protocols which are most often used. On the other hand, a part of the medicines used in the pharmacotherapy of stomach diseases in dogs are taken from the palette of medicines intended for human use, so that a regular dosage and regime of implementation are the main precondition for the success of the applied therapy. Drugs used in the treatment of stomach diseases include antiemetics, prokinetics, antacids, mucoprotectives, anticholinergics, H2-antagonists, proton pump inhibitors, semisynthetic derivatives of prostaglandin E1, and others. The therapy of stomach diseases implies the simultaneous application of several drugs from different pharmacodynamic groups (for instance, an antiemetic, a prokinetic, an antacid, and an Hg antagonist or a proton pump inhibitor when it is necessary to establish a correct regime of implementation because of possible interaction, which will also be discussed in this work.

Stomach emptiness in fishes: Sources of variation and study design implications

This study summarizes fish stomach content data from 369,000 fish from 402 species in 1,096 collections and reports on the percentage of individuals with empty stomachs. The mean percentage of individuals with empty stomachs among all species, locations, habitats, seasons, regions, and collection methods was 26.4%. Mean percentage of individuals with empty stomachs varied significantly among fish collection gear types, taxonomic orders, trophic groups, feeding behaviors, and habitats, and with species length at maturity. Most of the variation in percentage of individuals with empty stomachs was explained by species length at maturity, fish collection gear type, and two autecological factors: trophic group (piscivore percentage of individuals with empty stomachs > non-piscivore percentage of individuals with empty stomachs) and feeding habitat (water column feeder percentage of individuals with empty stomachs > benthic feeder percentage of individuals with empty stomachs). After accounting for variation with fish length, the percentage of individuals with empty stomachs did not vary with the stomach removal collection method (dissection vs. gastric lavage), feeding time (diurnal or nocturnal), or time of collection (day or night). The percentage of individuals with empty stomachs was similar between fresh and saltwater fish, but differed within finer habitat classifications and appeared to follow a general prey availability or productivity gradient: percentage of individuals with empty stomachs of open ocean collections > estuary collections, lentic > lotic, and pelagic > littoral. Gear type (active or passive) was the most influential factor affecting the occurrence of empty stomachs that can be readily controlled by researchers.

The gastroprotective effect of C. barometz leaves against ethanol-induced gastric hemorrhagic abrasions in Sprague Dawley rats has been evaluated in terms of medicinal properties. Seven groups of rats (normal control and ulcerated control groups, omeprazole 20 mg/kg, 62.5, 125, 250, and 500 mg/kg of C. barometz correspondingly were used in antiulcer experiment and pretreated with 10% Tween 20. After 1 hour, the normal group was orally administered 10% Tween 20, whereas absolute alcohol was fed orally to ulcerated control, omeprazole, and experimental groups. Gastric’s homogenate were assessed for endogenous enzymes activities. Stomachs were examined macroscopically and histologically. Grossly, the data demonstrated a significant decrease in the ulcer area of rats pretreated with plant extract in a dose-dependent manner with respect to the ulcerated group. Homogenates of the gastric tissue exhibited significantly increased endogenous enzymes activities in rats pretreated with C. barometz extract associated with the ulcerated control group. Histology of rats pretreated with C. barometz extract group using hematoxylin and eosin staining exhibited a moderate-to-mild disruption of the surface epithelium with reduction in submucosal edema and leucocyte infiltration in a dose-dependent manner.

Uncommon mucosal metastases to the stomach

Directory of Open Access Journals (Sweden)

Kanthan R

2009-08-01

Full Text Available Abstract Background Metastases to the stomach from an extra-gastric neoplasm are an unusual event, identified in less than 2% of cancer patients at autopsy. The stomach may be involved by hematogenous spread from a distant primary (most commonly breast, melanoma or lung, or by contiguous spread from an adjacent malignancy, such as the pancreas, esophagus and gallbladder. These latter sites may also involve the stomach via lymphatic or haematogenous spread. We present three cases of secondary gastric malignancy. Methods/Results The first is a 19-year-old male who received a diagnosis of testicular choriocarcinoma in September 2004. Metastatic malignancy was demonstrated in the stomach after partial gastrectomy was performed to control gastric hemorrhage. The second is a 75-year-old male, generally well, who was diagnosed with adenocarcinoma of the lung in September 2005. Poorly differentiated adenocarcinoma of the lung was demonstrated in a subsequent biopsy of "gastric polyps". The third is an 85-year-old man with no known history of malignancy who presented for evaluation of iron deficiency anemia by endoscopy in February 2006. Biopsies of the colonic and gastric mucosa demonstrated moderately differentiated invasive colonic adenocarcinoma with metastatic deposits in the stomach. Conclusion While the accurate recognition of these lesions at endoscopy is fraught with difficulty, pathological awareness of such uncommon metastases in the gastric mucosa is essential for accurate diagnosis and optimal patient management.

LPZ-loaded positively charged Eudragit® RS100 nanoparticles (ERSNPs-LPZ and negatively charged poly(lactic-co-glycolic acid nanoparticles (PLGANPs-LPZ were prepared. The effect of charge on nanoparticle deposition in ulcerated and non-ulcerated regions of the stomach was investigated. The cellular uptake of nanoparticles in the intestine was evaluated in a Caco-2 cell model. The pharmacokinetic performance and ulcer healing response of LPZ-loaded nanoparticles following oral administration were evaluated in Wistar rats with induced ulcers. The prepared drug-loaded ERSNPs-LPZ and PLGANPs-LPZ possessed opposite surface charge (+38.5±0.3 mV versus -27.3±0.3 mV, respectively and the particle size was around 200 nm with a narrow size distribution. The negatively charged PLGANPs adhered more readily to the ulcerated region (7.22%±1.21% per cm2, whereas the positively charged ERSNPs preferentially distributed in the non-ulcerated region (8.29%±0.35% per cm2. Both ERSNPs and PLGANPs were prominent uptake in Caco-2 cells, too. The nanoparticles sustained and prolonged LPZ concentrations up to 24 hours, and the half-life and mean residence time of LPZ were prolonged by 3.5-fold and 4.5-fold, respectively, as compared with LPZ solution. Oral administration of LPZ-loaded nanoparticles healed 92.6%–95.7% of gastric ulcers in Wistar rats within 7 days. Keywords: nanoparticles, lansoprazole, Eudragit® RS100, PLGA

The objective of this article was to study characteristics of pressure ulcer patients and their ulcers, pressure ulcer preventive and treatment measures in four Indonesian general hospitals. A multicentre cross-sectional design was applied to assess pressure ulcers and pressure ulcer care in adult patients in medical, surgical, specialised and intensive care units. Ninety-one of the 1132 patients had a total of 142 ulcers. Half (44·0%) already had pressure ulcers before admission. The overall prevalence of category I-IV pressure ulcers was 8·0% (95% CI 6·4-9·6), and the overall nosocomial pressure ulcer prevalence was 4·5% (95% CI 3·3-5·7). Most pressure ulcer patients had friction and shear problems, were bedfast, had diabetes and had more bedridden days. Most ulcers (42·3%) were category III and IV. One third of the patients had both pressure ulcers and moisture lesions (36·3%) and suffered from pain (45·1%). The most frequently used prevention measures were repositioning (61·5%), skin moisturising (47·3%), patient education (36·3%) and massage (35·2%). Most pressure ulcer dressings involved saline-impregnated or antimicrobial gauzes. This study shows the complexities of pressure ulcers in Indonesian general hospitals and reveals that the quality of pressure ulcer care (prevention and treatment) could be improved by implementing the recent evidence-based international guideline. © 2016 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

Adenosquamous carcinoma, a rare malignant tumor of the stomach, is characterized by the presence of two different cell components, one adenomatous and the other squamous. Adenosquamous carcinoma of the stomach tends to more aggressive clinicopathologic features than common adenocarcinoma. There are few reports about radiologic features of adenosquamous carcinoma of the stomach. We experienced a case of a primary adenosquamous carcinoma of the stomach in a 67-year-old man, and report here the ultrasonographic and computed tomographic (CT) findings

Cost-effectiveness of wound management in France: pressure ulcers and venous leg ulcers.

Meaume, S; Gemmen, E

2002-06-01

This study set out to define realistic protocols of care for the treatment of chronic venous leg ulcers and pressure ulcers in France and, by developing cost-effectiveness models, to compare the different protocols of care for the two ulcer groups, enabling a calculation of direct medical costs per ulcer healed in a typical French health insurance plan. Clinical outcomes and some treatment patterns were obtained from published literature. Validations of different treatment patterns were developed using an expert consensus panel similar to the Delphi approach. Costs were calculated based on national averages and estimates from the UK and Germany. The models were used to measure costs per healed ulcer over a 12-week period. For both the pressure ulcer and venous leg ulcer models, three protocols of care were identified. For pressure ulcers and venous leg ulcers, the hydrocolloid DuoDERM (ConvaTec, also known as Granuflex in the UK and Varihesive in Germany) was most cost-effective in France. The combination of published data and expert consensus opinion is a valid technique, and in this case suggests that treating pressure ulcers and venous leg ulcers with hydrocolloid dressings is more cost-effective than treating them with saline gauze, in spite of the lower unit cost of the latter.

Gastrin, secretin and cholecystokinin were determined by a radioimmunoassay in healthy persons (19) and in patients with peptic ulcer (13) on an empty stomach and after test breakfasts with different nutrients. In the healthy persons the blood concentration of regulatory peptides was lower than in the patients. Breakfasts increased the concentrations of gastrin, secretin and cholecystokinin in the patients much more than in the controls. Some differences in changes of the blood concentration of peptides were noted with regard to a type of test breakfast. However differentiated reactions of the endocrine apparatus of the gastroduodenal complex in response to the breakfasts were not a reliable functional and diagnostic criterion

Scanning of the stomach after administration of {sup 131}I and {sup 99m}Tc is presented. Experiments on 20 dogs were performed and 105 patients were examined. The studies with {sup 131}I are only mentioned briefly as they have been summarized in a previous publication and we have concentrated on our experience with {sup 99m}Tc and on stomach carcinoma. The turnover of the nuclide in blood, urine, gastric juice and gastric mucosa was tested: in-vivo and post-operative scannings were performed. The scans are classified in four groups. Carcinoma of the stomach results in space-occupying lesions or foggy scans. A correlation of 85 - 90% between scan results and clinical findings is noted. A special group of 10 volunteers was examined to establish the possibility of a screening examination for the detection of stomach cancer using the technique presented. (author)

Maytenus robusta (Celastraceae) is used in folk medicine for the treatment of stomach ulcers and is very well adapted to the South of Brazil. Maytenus ilicifolia is the main species of the Celastraceae family, and is used in the treatment of gastric ulcers. However, Maytenus ilicifolia is presently at the stage of extinction, due to indiscriminate use in Brazil. Thus, the use of Maytenus robusta in phytotherapeutic preparations, instead of Maytenus ilicifolia, is suggested. However, there have been no reports regarding the antiulcer activity of Maytenus robusta extract. Therefore, this study was carried out to evaluate the antiulcerogenic property of the hydroalcoholic extract of aerial parts of Maytenus robusta. The antiulcer assays were performed using the following protocols: nonsteroidal anti-inflammatory drug (NSAID)-induced ulcer, ethanol-induced ulcer, and stress-induced ulcer. The effects of the extract on gastric content volume, pH and total acidity, using the pylorus ligated model, were also evaluated. In the ethanol-induced ulcer model, it was observed that the treatment with Maytenus robusta extract significantly reduced the lesion index in 75.1 +/- 8.6, 85.0 +/- 9.2, 86.6 +/- 7.4 and 75.5 +/- 5.3 for the groups treated with 50, 250 and 500 mg/kg of Maytenus robusta and positive control (omeprazole 30 mg/kg), respectively. Also were observed significant inhibition in lesion index in the indomethacin-induced ulcer model, being the decrease of the 62.5 +/- 7.1, 62.5 +/- 6.1, 63.6 +/- 5.5 and 96.2 +/- 3.6 for groups treated with 50, 250 and 500 mg/kg of Maytenus robusta and positive control (cimetidine 100 mg/kg), respectively. Results similar were observed in the stress-induced ulcer model, where the inhibition of ulcer lesions were 71.3 +/- 5.5, 72.7 +/- 6.3, 76.5 +/- 7.1 and 92.3 +/- 7.5 for the groups treated with 50, 250 and 500 mg/kg of Maytenus robusta and positive control (cimetidine 100 mg/kg), respectively.

Previous structure-activity and pharmacologic studies with duodenal ulcerogens cysteamine and propionitrile implicating catecholamines in the pathogenesis of duodenal ulceration have now been followed up by dose- and time-response biochemical investigations to assess the importance of monoamines in the development of duodenal ulcers. The concentrations of norepinephrine (noradrenaline), dopamine, serotonin and their metabolites were measured in total brain, brain regions, stomach, duodenum, pancreas and adrenals in the rat. Turnover of catecholamines was determined in rats pretreated with the inhibitor of tyrosine hydroxylase alpha-methyl-p-tyrosine. The duodenal ulcerogens caused a dose- and time-dependent depletion of norepinephrine in virtually all the tissues examined. The effect was maximal 4 or 7 hr after cysteamine or propionitrile, and norepinephrine levels returned to normal in 24 hr. Dopamine changes were selective and often biphasic, e.g., elevation in adrenals, biphasic in brain cortex, hippocampus and midbrain, but uniformly decreasing in glandular stomach and duodenum. In the median eminence dopamine levels decreased by 181 and 324% at 15 and 30 min, respectively, after cysteamine, but neither dopamine nor 3,4-dihydroxyphenylacetic acid was modified in the periventricular nucleus. Serotonin levels were relatively stable, revealing slight elevations or no changes in most of the tissues. The turnover of norepinephrine was accelerated by both chemicals in virtually all brain regions, but dopamine turnover was affected only in a few areas, e.g., in the corpus striatum and medulla oblongata cysteamine decreased dopamine turnover, whereas propionitrile first (at 1 hr) accelerated then (at 8 hr) significantly suppressed it.(ABSTRACT TRUNCATED AT 250 WORDS)

History of Helicobacter pylori, duodenal ulcer, gastric ulcer and gastric cancer.

Science.gov (United States)

Graham, David Y

Helicobacter pylori (H. pylori) infection underlies gastric ulcer disease, gastric cancer and duodenal ulcer disease. The disease expression reflects the pattern and extent of gastritis/gastric atrophy (i.e., duodenal ulcer with non-atrophic and gastric ulcer and gastric cancer with atrophic gastritis). Gastric and duodenal ulcers and gastric cancer have been known for thousands of years. Ulcers are generally non-fatal and until the 20th century were difficult to diagnose. However, the presence and pattern of gastritis in past civilizations can be deduced based on the diseases present. It has been suggested that gastric ulcer and duodenal ulcer both arose or became more frequent in Europe in the 19th century. Here, we show that gastric cancer and gastric ulcer were present throughout the 17th to 19th centuries consistent with atrophic gastritis being the predominant pattern, as it proved to be when it could be examined directly in the late 19th century. The environment before the 20th century favored acquisition of H. pylori infection and atrophic gastritis (e.g., poor sanitation and standards of living, seasonal diets poor in fresh fruits and vegetables, especially in winter, vitamin deficiencies, and frequent febrile infections in childhood). The latter part of the 19th century saw improvements in standards of living, sanitation, and diets with a corresponding decrease in rate of development of atrophic gastritis allowing duodenal ulcers to become more prominent. In the early 20th century physician's believed they could diagnose ulcers clinically and that the diagnosis required hospitalization for "surgical disease" or for "Sippy" diets. We show that while H. pylori remained common and virulent in Europe and the United States, environmental changes resulted in changes of the pattern of gastritis producing a change in the manifestations of H. pylori infections and subsequently to a rapid decline in transmission and a rapid decline in all H. pylori-related diseases.

Full Text Available Background: In various studies, Cydonia oblonga Miller (quince has been reported to have many properties such as antioxidant and anti-ulcerative effects. This study has aimed to investigate the protective effects of quince aqueous extract (QAE and quince hydroalcoholic extract (QHE on gastric ulcer caused by indomethacin and the relevant macroscopic, histopathology, and biochemical factors in rats. Methods: Ten groups of male Wistar rats, six in each, were used in this study. These groups included: normal (distilled water, control (distilled water + indomethacin, reference (ranitidine or sucralfate + indomethacin, and test groups (QAE or QHE + indomethacin treated with three increasing doses (200, 500, and 800 mg/kg. Extracts and drugs were given orally to rats 1 h before injecting the indomethacin (25 mg/kg, intraperitoneally. Six hours later, the abdomen of rats was exposed, its pylorus was legated, gastric acid content was extracted, and its pH and the amount of pepsin secreted were measured by Anson method. Then, histopathology indices, ulcer area, ulcer index, and myeloperoxidase (MPO activity were measured in gastric mucus. Results: Both extracts of quince were effective to reduce the acidity of stomach and pepsin activity. Compared to control group, the average of enzyme activity of MPO was significantly declined in all treated groups. Control group had the highest level of gastric ulcer indices including severity, area, and index while the evaluated parameters had decreased in all extract treated groups although it seems that QAE was somewhat more effective. Conclusions: Protective effect of QAE and QHE on gastric ulcer was done by undermining offensive factors including decreasing the secretion of gastric acid and pepsin activity and by strengthening the protective factors of gastric mucus including antioxidant capacity.

Maintenance therapy with sucralfate in duodenal ulcer: genuine prevention or accelerated healing of ulcer recurrence?

Bynum, T E; Koch, G G

We sought to compare the efficacy of sucralfate to placebo for the prevention of duodenal ulcer recurrence and to determine that the efficacy of sucralfate was due to a true reduction in ulcer prevalence and not due to secondary effects such as analgesic activity or accelerated healing. This was a double-blind, randomized, placebo-controlled, parallel groups, multicenter clinical study with 254 patients. All patients had a past history of at least two duodenal ulcers with at least one ulcer diagnosed by endoscopic examination 3 months or less before the start of the study. Complete ulcer healing without erosions was required to enter the study. Sucralfate or placebo were dosed as a 1-g tablet twice a day for 4 months, or until ulcer recurrence. Endoscopic examinations once a month and when symptoms developed determined the presence or absence of duodenal ulcers. If a patient developed an ulcer between monthly scheduled visits, the patient was dosed with a 1-g sucralfate tablet twice a day until the next scheduled visit. Statistical analyses of the results determined the efficacy of sucralfate compared with placebo for preventing duodenal ulcer recurrence. Comparisons of therapeutic agents for preventing duodenal ulcers have usually been made by testing for statistical differences in the cumulative rates for all ulcers developed during a follow-up period, regardless of the time of detection. Statistical experts at the United States Food and Drug Administration (FDA) and on the FDA Advisory Panel expressed doubts about clinical study results based on this type of analysis. They suggested three possible mechanisms for reducing the number of observed ulcers: (a) analgesic effects, (b) accelerated healing, and (c) true ulcer prevention. Traditional ulcer analysis could miss recurring ulcers due to an analgesic effect or accelerated healing. Point-prevalence analysis could miss recurring ulcers due to accelerated healing between endoscopic examinations. Maximum ulcer

Purpose The association between stomach cancer and colorectal cancer is controversial. The purpose of this study was to determine the synchronous prevalence of colorectal neoplasms in patients with stomach cancer. Methods A total of 123 patients with stomach cancer (86 male) and 246 consecutive, age- and sex-matched persons without stomach cancer were analyzed from July 2005 to June 2010. All of them underwent colonoscopy within 6 months after undergoing gastroscopy. Results The prevalence of colorectal neoplasms was significantly higher in the stomach cancer group (35.8%) than in the control group (17.9%) (P neoplasms were more prevalent in the patients with stomach cancer (odds ratio [OR], 3.10; 95% confidence interval [CI], 1.71 to 5.63). In particular, the difference in the prevalence of colorectal neoplasms was more prominent in the patients above 50 years old (OR, 3.54; 95% CI, 1.80 to 6.98). Conclusion The results showed that the synchronous prevalence of colorectal neoplasms was higher in patients with stomach cancer than in those without stomach cancer. Therefore, patients with stomach cancer should be regarded as a high-risk group for colorectal neoplasms, and colonoscopy should be recommended for screening. PMID:22102975

Pressure ulcer prevention: an evidence based analysis The cost-effectiveness of prevention strategies for pressure ulcers in long-term care homes in Ontario: projections of the Ontario Pressure Ulcer Model (field evaluation) Management of chronic pressure ulcers: an evidence-based analysis (anticipated pubicstion date - mid-2009) Purpose A pressure ulcer, also known as a pressure sore, decubitus ulcer, or bedsore, is defined as a localized injury to the skin/and or underlying tissue occurring most often over a bony prominence and caused by pressure, shear, or friction, alone or in combination. (1) Those at risk for developing pressure ulcers include the elderly and critically ill as well as persons with neurological impairments and those who suffer conditions associated with immobility. Pressure ulcers are graded or staged with a 4-point classification system denoting severity. Stage I represents the beginnings of a pressure ulcer and stage IV, the severest grade, consists of full thickness tissue loss with exposed bone, tendon, and or muscle. (1) In a 2004 survey of Canadian health care settings, Woodbury and Houghton (2) estimated that the prevalence of pressure ulcers at a stage 1 or greater in Ontario ranged between 13.1% and 53% with nonacute health care settings having the highest prevalence rate (Table 1).

It has been used for decades in folkloric practice for the amelioration of various ailments. In this study, the gastroprotective activity of methanolic extract of C. excavata leaves (MECE was determined in the Sprague Dawley rat ethanol-induced gastric ulcer model. Rats were pretreated with a single dose of vehicle (5% Tween 20, 20 mg/mL omeprazole, 400 and 200 mg/mL of MECE dissolved in 5% Tween 20. Ulcer was induced with 5 mL/kg of ethanol and stomach tissue was obtained after 1 hour. Histological examination was done on hematoxylin and eosin, periodic acid-Schiff, and immunochemically stained gastric mucosal tissues. Prostaglandin E2, superoxide dismutase, catalase, glutathione peroxidase, and lipid peroxidation levels of the gastric tissue homogenates were also determined. Significantly (P<0.05 smaller ulcer areas, less intense edema, and fewer leukocytes’ infiltration were observed in MECE- and omeprazole-treated than in untreated gastric mucosa with ulcer. The gastric pH, mucus production, superoxide dismutase, catalase, and glutathione peroxidase contents increased, while the lipid peroxidation content decreased as a result of MECE treatment. Bcl-2-associated X protein was underexpressed, while heat shock protein 70 and transforming growth factor-beta protein were overexpressed in the ulcerated gastric mucosa tissues treated with omeprazole and MECE.

Helicobacter pylori (HP) are Gram-negative spiral bacteria which occur in the human stomach. The bacteria were cultured in vitro for the first time in 1983. It is suspected that the bacteria may cause chronic gastritis of type B and may also be a contributory cause of chronic ulceration and cancer...... of the stomach. The bacteria are accompanied by characteristic inflammatory changes in the gastric mucosa. The significance for gastritis, chronic ulceration, non-ulcer dyspepsia and carcinoma of the stomach is discussed.

In our previous study, the SLCO1B1 521TT genotype and the SLCO1B1*1b haplotype were significantly associated with the risk of peptic ulcer in patients taking low-dose aspirin (LDA). The aim of the present study was to investigate pharmacogenomic profile of LDA-induced peptic ulcer and ulcer bleeding. Patients taking 100 mg of enteric-coated aspirin for cardiovascular diseases and with a peptic ulcer or ulcer bleeding and patients who also participated in endoscopic surveillance were studied. Genome-wide analysis of single nucleotide polymorphisms (SNPs) was performed using the Affymetrix DME Plus Premier Pack. SLCO1B1*1b haplotype and candidate genotypes of genes associated with ulcer bleeding or small bowel bleeding identified by genome-wide analysis were determined using TaqMan SNP Genotyping Assay kits, polymerase chain reaction-restriction fragment length polymorphism, and direct sequencing. Of 593 patients enrolled, 111 patients had a peptic ulcer and 45 had ulcer bleeding. The frequencies of the SLCO1B1*1b haplotype and CHST2 2082 T allele were significantly greater in patients with peptic ulcer and ulcer bleeding compared to the controls. After adjustment for significant factors, the SLCO1B1*1b haplotype was associated with peptic ulcer (OR 2.20, 95% CI 1.24-3.89) and CHST2 2082 T allele with ulcer bleeding (2.57, 1.07-6.17). The CHST2 2082 T allele as well as SLCO1B1*1b haplotype may identify patients at increased risk for aspirin-induced peptic ulcer or ulcer bleeding. © 2014 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

Enteric neural crest cells regulate vertebrate stomach patterning and differentiation.

Science.gov (United States)

Faure, Sandrine; McKey, Jennifer; Sagnol, Sébastien; de Santa Barbara, Pascal

2015-01-15

In vertebrates, the digestive tract develops from a uniform structure where reciprocal epithelial-mesenchymal interactions pattern this complex organ into regions with specific morphologies and functions. Concomitant with these early patterning events, the primitive GI tract is colonized by the vagal enteric neural crest cells (vENCCs), a population of cells that will give rise to the enteric nervous system (ENS), the intrinsic innervation of the GI tract. The influence of vENCCs on early patterning and differentiation of the GI tract has never been evaluated. In this study, we report that a crucial number of vENCCs is required for proper chick stomach development, patterning and differentiation. We show that reducing the number of vENCCs by performing vENCC ablations induces sustained activation of the BMP and Notch pathways in the stomach mesenchyme and impairs smooth muscle development. A reduction in vENCCs also leads to the transdifferentiation of the stomach into a stomach-intestinal mixed phenotype. In addition, sustained Notch signaling activity in the stomach mesenchyme phenocopies the defects observed in vENCC-ablated stomachs, indicating that inhibition of the Notch signaling pathway is essential for stomach patterning and differentiation. Finally, we report that a crucial number of vENCCs is also required for maintenance of stomach identity and differentiation through inhibition of the Notch signaling pathway. Altogether, our data reveal that, through the regulation of mesenchyme identity, vENCCs act as a new mediator in the mesenchymal-epithelial interactions that control stomach development. © 2015.

Stomach cancer mortality among atomic bomb survivors in the Life Span Study was studied using death certificates for the period 1950-73. A consistent increase in mortality with increasing radiation dose was observed in Hiroshima, the highest rate being in the dose region of 400 - 499 rad. For Nagasaki, however, the evidence of a radiation effect is very weak. An excess in stomach cancer mortality was found only at doses above 500 rad. More evidence is needed to establish radiation as a causative factor in stomach cancer. (author)

The extracts of glycyrrhiza, Mentha and Melissa were tested for the antiulcerogenic activities against indomethacin induced ulcer in irradiated rats. Animals were irradiated at radiation dose levels 0.5, 1 and 2 Gy. The extracts were given orally 3 days after irradiation and the antiulcerogenic as well as the antisecretory and cyroprotective effects of the extracts were determined. All plant extracts produced pronounced antiulcerogenic activities and reduced acid output, increased mucin and decreased pepsin secretion in pyloric ligated rats. The antiulcerogenic activity of the plant extracts was also confirmed histologically. The effect of the plant extract could be party due to their flavonoids content and to their free radical scavenging properties. The stomach is a radiosensitive part of the gastriontestinal tract (Friedman, 1992). It does not tolerate radiation doses that are necessary to control cancer. Hoever, some parts of the stomach are often in the primary treatment field in radiotherapy

We report a case of a plexiform angiomyxoid myofibroblastic tumor of the stomach that developed in a 38-year-old woman who underwent gastrofiberscopy and multi-detector computed tomography scans due to dyspepsia for 3 months. There was a subepithelial protruding mass with a small central mucosal ulceration and heterogeneous prominent enhancement in the gastric upper body along the greater curvature. The tumor measured 3.5 x 2.3 cm in size and showed a multinodular plexiform growth pattern of bland spindle cells in the myxoid stroma with abundant small blood vessels. The tumor cells were negative for CD117 (c-KIT), CD34, and S-100 protein but diffusely positive for smooth muscle actin and Alcian blue. The pathologic examination demonstrated that the lesion was a plexiform angiomyxoid myofibroblastic tumor. The patient is doing well and has had no recurrence or metastasis for 6 months after the wedge resection.

Technetium-99m colloidal bismuth subcitrate: A novel method for the evaluation of peptic ulcer disease

The therapeutic agent colloidal bismuth subcitrate (CBS) selectively binds to peptic ulcers. The authors have developed a method for labeling this agent with Tc-99m. Chromatographic quality control studies of the agent on silica gel coated strips (ITLC-SG) showed that more than 97% of Tc-99m was bound to CBS. During in-vitro stability testing, the radio-label was stable for a minimum of 6 hours. The chromatographic findings are in agreement with the in-vivo distribution of the agent which showed no significant radioactivity in thyroid, kidneys, liver, or bladder. The resulting Tc-99m-CBS solution is administered orally in drinking water. Preliminary animal studies have been conducted on 5 adult 3 kg New Zealand rabbits sedated with 50 mg Ketamine I.M. The rabbits were intubated with I.V. tubing advanced to the stomach. They were given a gastric erosive suspension of 600-1000 mg/kg of pulverized ASA in 10 cc tap water. Four hours later they were given 3-4 mCi of the radiotracer in a 5 cc volume of water. Serial in-vivo images were obtained for 2 hours which included thyroid, abdomen, and urinary bladder. Next the stomachs were excised, opened along the greater curvature, imaged, vigorously washed and reimaged. All 5 rabbits showed avid localized binding of radiotracer which remained fixed even with vigorous washing. Areas of normal appearing mucosa were relatively devoid of radiotracer. This new compound may have significant clinical usefulness in the detection of peptic ulcer disease. In addition, such a non-invasive technique, carrying none of the risks or discomfort of endoscopy could also find application in the evaluation of the response to therapy

Objective was to determine the underlying cause of superficial skin ulcers over a 15-year period. A retrospective histopathological analysis of 670 cases of superficial skin ulcers diagnosed in the Dept. of Pathology, Ahmadu Bello University Teaching Hospital, Zaria, Nigeria from January 1991 to December 2005. A total of 670 superficial skin ulcers were analyzed. The mail to female gender ratio was 409:261(1.5:1.0) and a peakage frequency of 44.3 %( 297) in the 5th and 6th decades. Spectrum of lesions encountered was categorized into inflammatory, infections, benign and malignant diseases. The malignant lesions were 309 (46.1%), non-specific inflammation 302 (45.1%), granulation tissue 25 (3.7%) and pseudoepitheliomatous hyperplasia 14 (2.1%). A total of 18(2.7%) specific infections were encountered, which included bacterial, fungal and viral infection. Benign lesions were 2(0.3%), comprising of neurofibroma and Bowen's disease. The most common malignant lesion was squamous cell carcinoma 203 (30.3%) with a male to female ratio of 128:75 (1.7:1.0). Of these 161 were well differentiated tumors. The lower limb was the prevalent site distribution of all the ulcers. Superficial ulcers may be harbinger of malignant diseases. Squamous cell carcinoma remains the most common malignant lesion arising from chronic superficial ulcers from our setting. Adequate tissue biopsy and early diagnosis may reduce the attendant morbidity of these ulcers. (author)

To further understand the risk of stomach cancer after fractionated high-dose radiotherapy, we pooled individual-level data from three recent stomach cancer case-control studies. These studies were nested in cohorts of five-year survivors of first primary Hodgkin lymphoma (HL), testicular cancer...... (TC) or cervical cancer (CX) from seven countries. Detailed data were abstracted from patient records and radiation doses were reconstructed to the site of the stomach cancer for cases and to the corresponding sites for matched controls. Among 327 cases and 678 controls, mean doses to the stomach were...... 15.3 Gy, 24.7 Gy and 1.9 Gy, respectively, for Hodgkin lymphoma, testicular cancer and cervical cancer survivors, with an overall mean dose of 10.3 Gy. Risk increased with increasing radiation dose to the stomach cancer site (P

Hepatoid adenocarcinoma of the stomach: an unusual case of elevated alpha-fetoprotein with prior treatment for hepatocellular carcinoma

Full Text Available Hepatoid adenocarcinoma (HAC is a rare type of extrahepatic carcinoma whose morphology is similar to that of hepatocellular carcinoma (HCC. Metachronous HCC and HAC in the same patient is extremely rare. The case of a 68-year-old man with chronic hepatitis B infection who had both HCC and HAC of the stomach is reported herein. Nine years previously this patient had been diagnosed with HCC and received a right lobectomy. HCC that recurred at the caudate lobe at 6 months after the operation was successfully treated with transarterial chemoembolization. The patient was followed up regularly thereafter without evidence of tumor recurrence for 9 years. In July 2010 his serum alpha-fetoprotein (AFP level elevated from 6.5 ng/mL to 625.4 ng/mL, and he developed a probable single metastatic lymph node around the hepatic artery without intrahepatic lesions. Subsequent evaluation with upper endoscopy revealed a 4-cm ulcerative lesion on the antrum of the stomach. Subtotal gastrectomy was performed with lymph-node dissection. Histologic examination revealed a special type of extrahepatic AFP-producing adenocarcinoma-HAC with lymph-node metastasis-which indicates that HAC can be a cause of elevated AFP even in patients with HCC. HAC should be considered if a patient with stable HCC exhibits unusual elevation of AFP.

Full Text Available Non steroidal anti-inflammatory drugs (NSAIDs are commonly prescribed medications to the geriatric patients for the treatment of arthritis and other painful disorders. The major side effects of NSAIDs are related to their effects on the stomach and bowels. The present study concerns assessment of the potential of liquid in situ gelling emulsion formulations (emulgels as patient compliant stomach specific sustained release carrier for the delivery of highly gastric irritant drug, Piroxicam. Emulgels were prepared, without using any emulgent, by mixing different concentrations of molten Gelucire 39/01 with low viscosity sodium alginate solution prepared in deionized water at 50°C. CaCO3 was used as buoyancy imparting as well as crosslinking agent. Emulgels so prepared were homogenous, physically stable, and rapidly formed into buoyant gelled mass when exposed to simulated gastric fluid (SGF, pH 1.2. Drug release studies carried out in SGF revealed significant retardation (P<0.05 of Piroxicam release from emulgels compared to conventional in situ gelling formulations prepared without Gelucire 39/01. Pharmacodynamic studies carried out in albino rats revealed significantly increased analgesic/anti-inflammatory response from in situ emulgels compared to conventional in situ gelling formulations. Further, in vivo toxicity studies carried out in albino rats revealed no signs of gastric ulceration upon prolonged dosing.

1990-01-01

To determine the extent of tumoral process in patients with cancer of the stomach, roentgenoechoscopic methods for examining the stomach is developed. Three main versions of sonographic image of developed cancer of the stomach depending on the anatomical shape of tumors are considered. Possible resolutions of ultrasonic tomography in diagnostics of metastases and germination of cancer of the stomach to different organs and tissues in the abdominal cavity and retroperitoneal space are studied. It is established that the method provides to specify the location and echostructure of parenchimatous organs, to determine the number, shape, density and depth of metastases localization. It is shown that it is reasonable to carry out echoscopy of the stomach for all patients at the first stage of examination, when tumors in this organ are suspected. Ultrasonic tomography is recommended as a screening method to determine the extent of the tumoral process for patients with cancer of the stomach. It is noted that ultrasonic tomography is harmless, safe, simple in use and provides much information. 8 refs

Despite a declining incidence, stomach cancer is still a dominant cancer in Japan. The association between dietary habits and stomach cancer risk was investigated in a large prospective study in Japan. Data were obtained using a self-administered questionnaire from 1988 through 1990. Food frequency questionnaire was used to evaluate the consumption of 33 selected food items. Proportional hazard model was used to determine the hazard ratios (HRs) and their 95% confidence intervals (CIs) of stomach cancer for different levels of the dietary intakes. A western style breakfast showed an inverse association with stomach cancer risk in males (HR=0.49, 95% CI: 0.35-0.70). Women who consumed liver three to four times per week and more than once per day had a significant increased risk, respectively (HR=2.02, 95% CI: 1.12-3.63, HR=3.16, 95% CI: 1.16-8.62 ). A clear dose-response relationship between the intake of liver and stomach cancer risk was observed. We found no association between stomach cancer mortality and the consumption of fruit such as mandarin orange, and vegetables such as carrots and spinach in both men and women. The consumption of high salt foods such as miso soup and pickles was also not significantly associated with the mortality of stomach cancer in both sexes. This prospective study suggested that a western-style breakfast is associated with a lower risk of stomach cancer, although some differences in the association were seen between men and women.

A new method for diagnosing the Campylobacter Pylori in the stomach is described, using C-14 settled urease. Campylobacter Pylori is now being considered the most probable causative agent of antral chronic gastritis, pepitic ulcer and non-ulcerous dyspepsia. The technique is based on ingestion of the tracer, its recovery by exhalation in etanol hyamine solution, followed by counting and dates evaluation. The test was applied to forty two voluntary male and female patients, after their written acquiescence. Their ages varied from 19 to 62 years old. Thirty of the results were positive and twelve negative. All of them were comproved by microbiological (cultura) and hystologycal studies of gastric biopsy gotten by gastroscopy. They were performed at the Gastroentherology Departament of the 'Hospital das Clinicas' that belongs to the Federal University of Minas Gerais. Repetitivity of the breath test was confirmed by repetition of the results in five positive patients and five negative ones. (author).

Reevaluation of benefit and risk of mass screening for stomach cancer

International Nuclear Information System (INIS)

Iinuma, Takeshi; Tateno, Yukio

1990-01-01

Mass screening for stomach cancer has been performed widely because of the the most prevalent malignancy in Japan. Since X-ray diagnosis is used in stomach cancer screening, the risk of X-ray exposure must be considered by comparing the benefit of mass screening. We have reported in the previous article in 1977 that the benefit and risk of stomach cancer mass screening become equal at the age of 40 yr. Since then, various conditions of the mass screening for stomach cancer have changed so that reevaluation of the benefit and risk relationship is necessary. The risk coefficient of radiation-induced stomach cancer has been revised drastically in the report of United Nations Scientific Committee on the effects of radiation in 1988. In this report, the benefit of mass screening of stomach cancer is defined as the net elongation of average life expectancy due to the life saved, and the risk of the screening is defined as the net shortage of average life expectancy due to the radiation-induced stomach cancer and leukemia. Since the benefit increases rapidly and the risk decreases with age, an appropriate age when the benefit and risk become identical is required, and under this age the mass screening is not justified to be performed. Assuming X-ray dose equivalent to stomach of 10 mSv and risk coefficient of stomach cancer of 12.6x10 -3 Sv -1 from the United Nations report, the critical age is found to be about 35 yr. for men and women. It is strongly recommended that the dose equivalent should be lowered less than 5 mSv. In a calculation of the risk of endoscopic examination in mass screening using reported figures of fatal accident (1.6x10 -5 ) and severe injury (48x10 -5 ) of the stomach endoscopic examination, the critical ages are found to be 40 yr for men and 45 yr for women which are higher than those with X-rays. A screening test using stomach endoscopy cannot be accepted. (J.P.N.)

Novel raft forming systems incorporating curcumin-Eudragit® EPO solid dispersions were developed to prolong the gastric residence time and provide for a controlled release therapy of curcumin to treat gastric ulcers. The solid dispersions of curcumin with Eudragit® EPO were prepared by the solvent evaporation method at various ratios to improve the solubility and the dissolution of curcumin. The optimum weight ratio of 1:5 for curcumin to Eudragit® EPO was used to incorporate into the raft forming systems. The raft forming formulations were composed of curcumin-Eudragit® EPO solid dispersions, sodium alginate as a gelling polymer and calcium carbonate for generating divalent Ca(2+) ions and carbon dioxide to form a floating raft. All formulations formed a gelled raft in 1min and sustained buoyancy on the 0.1N hydrochloric acid (pH 1.2) surface with a 60-85% release of curcumin within 8h. The curative effect on the acetic acid-induced chronic gastric ulcer in rats was determined. The curcumin raft forming formulations at 40mg/kg once daily showed a superior curative effect on the gastric ulcer in terms of the ulcer index and healing index than the standard antisecretory agent: lansoprazole (1mg/kg, twice daily) and a curcumin suspension (40mg/kg, twice daily). These studies demonstrated that the new raft forming systems containing curcumin solid dispersions are promising carriers for a stomach-specific delivery of poorly soluble lipophilic compounds.

To estimate the Heart rate variability (HRV), by the method of daily kholterovskogo monitoring in the workers of rail transport (RT). A total of 93 persons working in the East Siberian Railway. The main group (CG) consisted of 27 patients with gastric ulcer (GU) and duodenal ulcer (DU) contamination without Helicobacter infection. The first group of clinical comparison (GCS 1) included 36 patients with gastric ulcer and duodenal with contamination of infection H. pylori. The second group of clinical comparison (GCS 2) consisted of 30 employees VT held preventive medical examination, without contamination of Helicobacter infection is not suffering from gastric ulcer and duodenum. With the analysis of spectral and time characteristics HRV in Haug is revealed the explicit displacement of vegetative homeostasis with the prevalence of the sympathetic component of regulation, which is restored against the background of treatment. Meanwhile in GKS1 the indices of vegetative regulation had parasympathetic directivity, they were more close to the standard and did not change after conducting of the eradikatsionnoy therapy. The greatest unbalance of sympathetic and parasympathetic nervous system is observed in patients, workers (RT), who suffer SU and UD in the absence of the contamination of H. pylori. The use of a method of study VCR in the conditions of the absence of H. pylori infection can make it possible to form the group of risk of development SU and UD in workers RT.

This study investigates the gastroprotective effects of hecogenin, a steroid saponin isolated from Agave sisalana, on experimental models of gastric ulcer. Male Swiss mice were used in the models of ethanol- and indometacin-induced gastric ulcer. To clarify the hecogenin mechanism of action, the roles of nitric oxide (NO), sulfhydryls (GSH), K⁺(ATP) channels and prostaglandins were also investigated, and measurements of lipid peroxidation (TBARS assay) and nitrite levels in the stomach of hecogenin-treated and untreated animals were performed. Furthermore, the effects of hecogenin on myeloperoxidase (MPO) release from human neutrophils were assessed in vitro. Our results showed that hecogenin (3.1, 7.5, 15, 30, 60 and 90 mg/kg, p.o.) acutely administered, before ethanol or indomethacin, exhibited a potent gastroprotective effect. Although the pretreatments with L-NAME, an iNOS inhibitor, and capsazepine, a TRPV1 receptor agonist, were not able to reverse the hecogenin effect, this was reversed by glibenclamide, a K⁺(ATP) blocker, and indomethacin in the model of ethanol-induced gastric lesions. The hecogenin pretreatment normalized GSH levels and significantly reduced lipid peroxidation and nitrite levels in the stomach, as evaluated by the ethanol-induced gastric lesion model. The drug alone increased COX-2 expression and this effect was further enhanced in the presence of ethanol. It also decreased MPO release and significantly protected the gastric mucosa. In conclusion, we showed that hecogenin presents a significant gastroprotective effect that seems to be mediated by K⁺(ATP) channels opening and the COX-2/PG pathway. In addition, its antioxidant and anti-inflammatory properties may play a role in the gastroprotective drug effect. Copyright © 2012 Elsevier B.V. All rights reserved.

We previously reported that cascade stomach was associated with reflux symptoms and esophagitis. Delayed gastric emptying has been believed to initiate transient lower esophageal sphincter relaxation (TLESR). We hypothesized that cascade stomach may be associated with frequent TLESR with delayed gastric emptying. Eleven subjects with cascade stomach and 11 subjects without cascade stomach were enrolled. Postprandial gastroesophageal manometry and gastric emptying using a continuous 13C breath system were measured simultaneously after a liquid test meal. TLESR events were counted in early period (0–60 min), late period (60–120 min), and total monitoring period. Three parameters of gastric emptying were calculated: the half emptying time, lag time, and gastric emptying coefficient. The median frequency of TLESR events in the cascade stomach and non-cascade stomach groups was 6.0 (median), 4.6 (interquartile range) vs 5.0, 3.0 in the early period, 5.0, 3.2 vs 3.0, 1.8 in the late period, and 10.0, 6.2 vs 8.0, 5.0 in the total monitoring period. TLESR events were significantly more frequent in the cascade stomach group during the late and total monitoring periods. In contrast, gastric emptying parameters showed no significant differences between the two groups. We concluded that TLESR events were significantly more frequent in persons with cascade stomach without delayed gastric emptying. PMID:28584403

Currently, there is a lack of consensus regarding the accepted terminology pertaining to the pressure ulcer healing progression and recidivism. This lack of uniformity can negatively impact initiation of treatment pathways, completion of appropriate interventions, clinical documentation, medical coding, patient education, discharge planning and healthcare revenue through out the healthcare system. The purpose of this paper is to introduce a standard nomenclature as it pertains to pressure ulcer healing progression and any recidivism that may occur. The National Pressure Ulcer Advisory Panel has formulated a framework of terms regarding pressure ulcer progression. We also developed a clearer nomenclature for lack of progress and recidivism of pressure ulcers. This document should serve as a starting point for the discussion of the pressure ulcer care, research, and terminology. © 2014 by the Wound Healing Society.

Full Text Available Gastric cancer can have protean manifestations, usual symptoms mimicking those of peptic ulcer disease. Gastric adenocarcinomas have rarely been reported with leptomeningeal carcinomatosis (LMC and dermatoses as initial presenting features. It is also difficult to diagnose breast metastasis of gastric carcinoma due to its rarity. We report two such cases with rare initial presentation. Our first case was a 46-year-old male who presented with LMC. Our second case was a 24-year-old male whose initial complaints were shortness of breath, bilateral breast lumps, and skin discoloration. Both cases on further investigations were found to have primary tumors in the stomach.

Fish stomach contents in benthic macroinvertebrate assemblage assessments

Directory of Open Access Journals (Sweden)

TH. Tupinambás

Full Text Available The choice of sampling gears to assess benthic macroinvertebrate communities depends on environmental characteristics, study objectives, and cost effectiveness. Because of the high foraging capacity and diverse habitats and behaviors of benthophagous fishes, their stomach contents may offer a useful sampling tool in studies of benthic macroinvertebrates, especially in large, deep, fast rivers that are difficult to sample with traditional sediment sampling gear. Our objective was to compare the benthic macroinvertebrate communities sampled from sediments with those sampled from fish stomachs. We collected benthic macroinvertebrates and fish from three different habitat types (backwater, beach, riffle in the wet season, drying season, and dry season along a single reach of the Grande River (Paraná River Basin, southeast Brazil. We sampled sediments through use of a Petersen dredge (total of 216 grabs and used gill nets to sample fish (total of 36 samples. We analyzed the stomach contents of three commonly occurring benthophagous fish species (Eigenmannia virescens, Iheringichthys labrosus, Leporinus amblyrhynchus. Chironomids dominated in both sampling methods. Macroinvertebrate taxonomic composition and abundances from fish stomachs differed from those from sediment samples, but less so from riffles than from backwater and beach habitats. Macroinvertebrate taxa from E. virescens stomachs were more strongly correlated with sediment samples from all three habitats than were those from the other two species. The species accumulation curves and higher mean dispersion values, compared with with sediment samples suggest that E. virescens is more efficient than sediment samples and the other fish studied at collecting benthic taxa. We conclude that by analyzing the stomach contents of benthophagous fishes it is possible to assess important characteristics of benthic communities (dispersion, taxonomic composition and diversity. This is especially true

Helicobacter pylori is associated with peptic ulcer disease and gastric cancer. Therefore we wanted to test how various lengths of delays in H pylori eradication therapy influence the risk of recurrent peptic ulcer, ulcer adverse events, and gastric cancer. This population-based nationwide Swedish cohort study included 29,032 patients receiving H pylori eradication therapy after peptic ulcer disease in 2005 to 2013. Predefined time intervals between date of peptic ulcer diagnosis and date of eradication therapy were analyzed in relation to study outcomes. Cox regression provided hazard ratios (HRs) and 95% confidence intervals (95% CIs), adjusted for age, sex, comorbidity, history of ulcer disease, use of ulcerogenic drugs, and use of proton pump inhibitors (PPIs). Compared with eradication therapy within 7 days of peptic ulcer diagnosis, eradication therapy within 8 to 30, 31 to 60, 61 to 365, and >365 days corresponded with HRs of recurrent ulcer of 1.17 (95% CI, 1.08-1.25), 2.37 (95% CI, 2.16-2.59), 2.96 (95% CI, 2.76-3.16), and 3.55 (95% CI, 3.33-3.79), respectively. The corresponding HRs for complicated ulcer were 1.55 (95% CI, 1.35-1.78), 3.19 (95% CI, 2.69-3.78), 4.00 (95% CI, 3.51-4.55), and 6.14, (95% CI, 5.47-6.89), respectively. For gastric cancer the corresponding HRs were .85 (95% CI, .32-2.23), 1.31 (95% CI, .31-5.54), 3.64 (95% CI, 1.55-8.56), and 4.71 (95% CI, 2.36-9.38), respectively. Delays in H pylori eradication therapy after peptic ulcer diagnosis time-dependently increase the risk of recurrent ulcer, even more so for complicated ulcer, starting from delays of 8 to 30 days.

Mass examinations of the stomach were performed on 13,412 a-bomb survivors from Oct. 1975 to Mar. 1979. The necessity rate for detailed examinations was 13.6% on the average, and it was a little lower than the average in Japan. That in women was higher than that in men. The performance rate of detailed examinations was very high (91.8%), which might be influenced by active appeals to have detailed examinations. The estimated discovery rate of stomach cancer was 0.27% on the average, and it was higher than that in mass examinations of Chugoku and Shikoku districts. A relationship between the estimated discovery rate of stomach cancer and exposure conditions was not clarified. The discovery rate of stomach cancer was supposed to be influenced strongly by aging of a-bomb survivors. (Tsunoda, M.)

Peptic ulcer imaging with /sup 99m/Tc sucralfate and possible advantages of /sup 99m/Tc sucrose octasulfate

International Nuclear Information System (INIS)

CentiColella, A.; Scopinaro, F.

1986-01-01

Sucralfate is a basic aluminum salt of sucrose octasulfate that protects the damaged mucosa and also the normal mucosa from peptic aggression. In fact sucralfate adheres to the mucosa as pH decreases below 4, and buffers the acid, slowly releasing sucrose octasulfate that forms insoluble complexes with the proteins exuded by the ulcers, or is washed out of the stomach. Sucralfate itself is also able to precipitate with proteins in the ulcers. Sucralfate may be labelled by several methods: /sup 99m/Tc HSA, /sup 99m/Tc DTPA, /sup 75/Se, /sup 111/In. The aims of this study were to evaluate the clinical results obtained using /sup 99m/Tc DTPA sucralfate, which the authors believe is the only labelled sucralfate suitable for clinical studies and to discuss the possible diagnostic uses of /sup 99m/Tc sucrose octasulfate. In fact, it has been possible to label the sucrose octasulfate either with /sup 99m/Tc DTPA or with /sup 99m/Tc without the use of intermediate ligands

Biochanin A notable bioactive compound which is found in so many traditional medicinal plant. In vivo study was conducted to assess the protective effect of biochanin A on the gastric wall of Spraguedawley rats` stomachs. The experimental set included different animal groups. Specifically, four groups with gastric mucosal lesions were receiving either a) Ulcer control group treated with absolute ethanol (5 ml/kg), b) 20 mg/kg of omeprazole as reference group, c) 25 of biochanin A, d) 50 mg/kg of biochanin A. Histopathological sectioning followed by immunohistochemistry staining were undertaken to evaluate the influence of the different treatments on gastric wall mucosal layer. The gastric secretions were collected in the form of homogenate and exposed to superoxide dismutase (SOD) and nitric oxide enzyme (NO) and the level of malondialdehyde (MDA) and protein content were measured. Ulceration and patchy haemorrhage were clearly observed by light microscopy. The morphology of the gastric wall as confirmed by immunohistochemistry and fluorescent microscopic observations, exhibited sever deformity with notable thickness, oedematous and complete loss of the mucosal coverage however the biochanin-pretreated animals, similar to the omeprazole-pretreated animals, showed less damage compared to the ulcer control group. Moreover, up-regulation of Hsp70 protein and down-regulation of Bax protein were detected in the biochanin A pre-treated groups and the gastric glandular mucosa was positively stained with Periodic Acid Schiff (PAS) staining and the Leucocytes infiltration was commonly seen. Biochanin A displayed a great increase in SOD and NO levels and decreased the release of MDA. This gastroprotective effect of biochanin A could be attributed to the enhancement of cellular metabolic cycles perceived as an increase in the SOD, NO activity, and decrease in the level of MDA, and also decrease in level of Bax expression and increase the Hsp70 expression level.

A 77-year-old woman was referred to us on Dec. 22, 1986 because of dysphagia and esophageal ulcer. She had a previous history of left radical mastectomy for breast cancer, followed by postoperative 60 Co irradiation to parasternal and supraclavicular regions with 50 Gy about 15 years before. UGIs and endoscopy showed a small ulcer surrounded by submucosal tumor-like protrusion in the esophagus at the thoracic inlet. Examination one month later revealed the ulcer which became larger despite medical treatment, now measuring 1 cm in diameter. Severe dysphagia continued. Right thoractomy and subtotal esophagectomy were performed on Jan 13, 1987. Histological examination revealed nonspecific ulcer, 5 cm in diameter, surrounded by fibrous granulation tissue. Proliferation of dilated capillary vessels was also seen in the bottom of the ulcer, the surrounding wall of which was free from remarkable infiltration of inflammatory cells. Based on these findings and previous medical history, the patient was diagnosed as having a postirradiation ulcer which appeared 15 years after irradiation. Dysphagia was considered due to esophageal dysfunction caused by severe fibrosis of the proper muscle layer. (author)

The adult Drosophila copper cell region or "stomach" is a highly acidic compartment of the midgut with pH stem cells (GSSCs) produces the acid-secreting copper cells, interstitial cells, and enteroendocrine cells of the stomach. Our assays demonstrate that GSSCs are largely quiescent but can be induced to regenerate the gastric epithelium in response to environmental challenge. Finally, genetic analysis reveals that adult GSSC maintenance depends on Wnt signaling. Characterization of the GSSC lineage in Drosophila, with striking similarities to mammals, will advance the study of both homeostatic and pathogenic processes in the stomach.

2016-10-01

Intrathoracic stomach is a rare and serious congenital abnormality. The anomaly may be complicated by gastric volvulus and can lead to ischemic gastric infarction in the neonate. If diagnosed antenatally, neonatal management can be planned in advance so as to reduce morbidity. This anomaly must be differentiated from the more common congenital diaphragmatic hernia, as associated pulmonary hypoplasia is common in the latter and rare with gastric herniation. We report a case of intrathoracic stomach in a neonate without volvulus, fortunately a rare entity which was managed operatively, and the child has been under regular follow-up.

Full Text Available Objective: to compare clinical manifestations, course, mental status in duodenal ulcer (DU patients with a history of perforated ulcer and its uncomplicated course.Subjects and methods. One hundred and thirteen patents with DU were examined. Group 1 included 61 patients with uncomplicated DUand Group 2 comprised 52 patients with a history of perforated ulcer. A comparison group consisted of 20 patients who had undergone laparotomy. Physical and mental status examinations, esophagogastroduodenoscopy (EGDS, and 24-hour pH-metry were performed.Results. Classical pain syndrome was observed in 75 % of the patients with uncomplicated DU. Prior to perforation, the pain and dyspeptic syndromes were distinguished only by a significantly lower degree in Group 2; following perforation, the pain syndrome was recorded more frequently, it was more extensive, meal-unrelated, and similar to that in the patients who had undergone laparotomy and had diminished appetite (36.5 %. EGDS showed that the complicated course was accompanied by the significantly higher incidence of erosive esophagitis (21.2 %, gastritis (51.9 %, duodenitis (25.0 %, multiple ulcers (28.8 %, and larger ulcers. 24-hour pH-metry indicated that the level of hyperacidity in Group 2 was higher and the circadian intragastric pH variations were less marked than those in uncomplicated DU. The patients with a history of perforated ulcer showed a high rate of anxiety and depressive changes. Conclusion. In complicated DU, marked monotonic hyperacidity causes common erosive-ulcerative lesions in the gastroduodenal area in relatively mild pain syndrome, late referrals, and long-term ulcer healing. After perforation followed by wound closure, the pain and dyspeptic syndromes become more pronounced, which is associated with anxiety and depressive changes in the mental status, as well as with early referrals and less healing time.

2008-01-01

Giant duodenal ulcers (GDUs) are a subset of duodenal ulcers that have historically resulted in greater morbidity than usual duodenal ulcers. Until recently,few cases had been successfully treated with medical therapy. However, the widespread use of endoscopy,the introduction of H-2 receptor blockers and proton pump inhibitors, and the improvement in surgical techniques all have revolutionized the diagnosis,treatment and outcome of this condition. Nevertheless,GDUs are still associated with high rates of morbidity,mortality and complications. Thus, surgical evaluation of a patient with a GDU should remain an integral part of patient care. These giant variants, while usually benign, can frequently harbor malignancy. A careful review of the literature highlights the important differences when comparing GDUs to classical peptic ulcers and why they must be thought of differently than their more common counterpart.

Full Text Available BACKGROUND Interest in human development is very widespread largely because of the curiosity about our beginnings and desire to improve the quality of life. Understanding of the processes involved in the formation of various organs and systems has unrevealed most cryptic secrets of the nature. Human development begins at fertilisation when a male gamete or sperm unites with a female gamete or oocyte to form a single cell, a zygote. With the formation of zygote (single-celled stage, foetal development begins. The aim of the study is to- 1 Study the morphometric parameters of foetal stomach at various gestational ages. 2 Compare these observations with the previous studies. MATERIALS AND METHODS Present work was the cross-sectional study carried out in the Department of Anatomy in collaboration with the Department of Obstetrics and Gynaecology at SRTRGMC and Hospital, Ambajogai Dist., Beed, Maharashtra. For this, approval of Institutional Ethical Committee was taken. 30 aborted human foetuses of different age groups ranging from 12 to 36 weeks of fertilisation were taken from the Department of OB-GYN. Foetuses were preserved by using 10% formalin. Age of foetuses were determined by crown-rump length and history given by mother. Foetuses were dissected after preservation for 15 days and morphometric studies were done on stomach. RESULTS Various quantitative parameters like weight of foetus, crown-rump length, total length of stomach, weight of stomach, length of greater curvature, lesser curvature, width of cardia and width of pylorus were used. For the purpose of study and comparison with other researchers, the foetuses were divided into 3 groups. Morphometric changes were observed in different groups and compared with previous studies. CONCLUSION With the increase in the body weight, crown-rump length and gestational age of the foetus, there is gradual increase on various parameters of stomach.

To measure the prevalence of incontinence in the 2013-2014 International Pressure Ulcer Prevalence (IPUP) surveys and determine the relative risk of developing a facility-acquired pressure ulcers (FAPUs) by stage and by Braden Scale score groupings. The IPUP survey is an observational, cross-sectional cohort database designed to determine the frequency and severity of pressure ulcers in various populations. The survey includes acute care (91.4%), long-term acute care (1.7%), rehabilitation patients (1.7%) and long-term care residents (5.2%). Geographic distribution included 182,832 patients in the United States, 22,282 patients in Canada, and the rest of the world, primarily in Europe and the Middle East. We analyzed data from the 2013 and 2014 IPUP surveys to better understand the relationship between incontinence and the frequency and severity of FAPUs. The IPUP survey is an annual voluntary survey of patients who are hospitalized or who reside in long-term care facilities. Data were collected over a 24-hour period within each participating facility. Data collection included limited demographics, presence and stage of pressure ulcers, and pressure ulcer risk assessment score (Braden Scale for Pressure Sore Risk, Braden Q, Norton, Waterlow, and others). In addition, data were collected on pertinent pressure ulcer risk factors including the number of linen layers, use of a pressure redistributing surface, adherence to repositioning schedule, and whether moisture management was provided in the last 24 hours. We aggregated data by urinary, urinary catheter, fecal, fecal management system, double (urinary and fecal), and ostomy incontinence category. If patients were managed by indwelling urinary catheter or fecal management systems, they were considered incontinent in this analysis. In order to analyze ulcers likely to be affected by incontinence, we defined a subset of ulcers as Relevant Pressure Ulcers, which are ulcers that are facility-acquired, non

A Direct Comparison of Anti-ulcer Effects of Coenzyme Q10 and Vitamin C on Indomethacin-induced Gastric Ulcer in Rat: A Controlled Experimental Study

Directory of Open Access Journals (Sweden)

2013-08-01

Full Text Available Introduction: Indomethacin increases generation of mitochondrial reactive oxygen species (ROS which have a crucial role in the indomethacin-induced gastric ulcer. Coenzyme Q10 has an antioxidant activity on mitochondria and cell membranes and protects lipids from oxidation and is essential for stabilizing biological membranes. Superoxide dismutase (SOD acts as one of the defense mechanisms against free radicals. When the generation of ROS overwhelms, the antioxidant defense, lipid peroxiation of cell membrane occurs and cause cell damage. Materials and Methods: Male adult Wistar rats were divided into A and B groups. The rats in group A were then further divided into three subgroups of 6 animals each and received one of the following treatments: Animals in the first subgroup received saline. Animals in the second subgroup received saline and indomethacin. Animals in the third subgroup received vitamin C and indomethacin. The rats in group B were also further divided into 3 subgroups of 6 rats each and treated with one of the following treatments: Animals in first subgroup received 1% Tween 80 as vehicle. Animals In second subgroup received 1% Tween 80 and indomethacin. Animals in third subgroup received CoQ10 and indomethacin. Four hours after the last treatment, animals were killed and the stomachs removed were cut and gastric mucosal lesions were examined. Ulcer indexes were determined and SOD activity measured in plasma                                                             Results: Pretreatment with both vitamin C and coenzyme Q10 was associated with attenuation of ulcer index and increased SOD activity compared with animals treated with indomethacin alone (P

The radiologic upper G.I. series and gastroscopic examination with gastric biopsies of 230 cases were carried out in Korea General Hospital for the purpose of pursuit of significance of coarsened gastric rugae. Out of the above series the 26 cases showing mere radiologic finding of coarsening of the gastric mucosal rugae were selected, excluding the cases with definite evidence of ulceration, malignancies and others. The correlativity of the coarsened gastric rugae was investigated with clinical pictures, gastroscopic features and biopsy findings. The following results were obtained: 1. There were 24 cases of gastritis, 5 of stomach ulcer and 2 of stomach cancer in the 26 cases with mere finding of mucosal coarsening. 2. There was 5 cases of stomach ulcer disease revealing no radiologic evidence, but there were found tiny ulcers in 4 cases and a large ulcer crater of 1.0 cm by 1.5 cm in diameter in the other case under the gastroscopic study. 3. Two cases of stomach cancer were not detected in neither radiologic nor gastroscopic examination, however, they were found by gastric biopsy. 4. It should be strongly emphasized that the biopsy under the gastroscopic control must be followed when a radiologic evidence of coarsened gastric rugae is demonstrated.

[Drug-induced oral ulcerations].

Science.gov (United States)

Madinier, I; Berry, N; Chichmanian, R M

2000-06-01

Different side effects of drugs have been described in the oral cavity, including oral ulcerations. Direct contact between drugs and oral mucosa may induce chemical burn or local hypersensitivity. Less frequently, these drug-induced oral ulcerations are part of a complex reaction with cutaneous or systemic manifestations. Sometimes, one or more oral ulcerations appear as the main side-effect of a drug, or exceptionally as solitary lesions. Solitary oral ulcerations usually appear after few weeks of treatment. In most of cases, these lesions resist to conventional treatments, with a rapid healing following the suppression of the responsible drug. This diagnosis is usually difficult, particularly with patients receiving multiple drug therapy. Besides, special attention must be paid to new drugs. Oral ulcerations following symptoms of burning mouth, metallic taste, dysgueusia or agueusia are strongly suggestive of a pharmacological origin. Most of the molecules able to induce solitary oral ulcerations are commonly prescribed in a) rheumatology: NSAI (diclofenac, flurbiprofen, indomethacin, naproxen), long-term rheumatoid arthritis therapy (azathioprine, methotrexate, penicillamine, gold compounds, tiopronin); b) cardiology: angiotensin-converting-enzyme inhibitors (captopril, enalapril), angiotensin 2-receptor antagonist (losartan), anti-angorous (nicorandil), c) psychiatry: antidepressants (fluoxetine, lithium), d) AIDS therapy (foscarnet, zalcitabine).

Full Text Available Pressure ulcer is a signifcant problem in elderly and critically ill patients, causing pain, decreasing quality of life and leading to prolonged hospital stay. Treatment of pressure ulcer to improve health status is a cost-effective approach. So, preventing the ulcers will be economical. Pressure ulcer is considered as a damage or necrosis of skin and its layers, which happens when there is a considerable pressure over the tissues. If the capillary arterie's pressure reaches 70 mmHg (2 times more than the normal pressure pressure ulcer happens and depending on the depth of the ulcer, will be divided into 4 stages. The most important point for preventing the ulcers is reducing the pressure. Patients should be repositioned to relieve or minimize the tissue pressure. Considering the type of the ulcer, the necessary treatment (dressing, Antibiotic Therapy, debridement or surgery should be performed.

Gastric injury from 90Y to left hepatic lobe tumors adjacent to the stomach: fact or fiction?

Radioembolization with 90 Y microspheres is a locoregional radiation therapy for unresectable hepatic neoplasm. Non-target delivery of 90 Y microspheres resulting in gastrointestinal (GI) symptoms is a recognized complication; there is minimal knowledge regarding the radiation effect to the gastric wall from left hepatic lobe 90 Y treatments. Our aim was to study the incidence of GI complications when the target tissue (hepatic parenchyma ± tumor) is in close proximity to the gastric wall. We hypothesized that liver (tumor) to stomach proximity does not correlate with increased toxicity. Between November 2011 and September 2013, we studied all patients who underwent left lobe radioembolization with 90 Y glass microspheres. With Institutional Review Board (IRB) approval, we retrospectively reviewed MRI/CT images of these patients, identifying a subset of patients with the left hepatic lobe <1 cm from the gastric wall. Patients were seen in clinic 1 month posttreatment and subsequently at 3-month intervals. Short- and long-term gastric adverse events were tabulated. Ninety-seven patients successfully underwent left hepatic lobe 90 Y microsphere radioembolization in which the average distance from the liver to the stomach wall was 1.0 ± 2.8 mm. The average dose for patients who received radioembolization to the left hepatic lobe was 109 ± 57 Gy. Fifty patients had tumor within 1 cm of the gastric wall. The average dose for patients who received radioembolization to the left hepatic lobe with tumor within 1 cm of the gastric wall was 121 ± 41 Gy. There were no reportable or recordable medical events. Of the patients, 34 % reported abdominal pain that was grade 1-2; 65 % of the patients reported no abdominal pain. None of the 97 patients developed a clinically evident GI ulcer. Patients with left lobe tumors adjacent to or abutting the stomach do not exhibit acute or chronic radiation effects following radioembolization with glass microspheres. (orig.)

2000-08-01

Twenty stomachs of Bactrian camels (Camelus bactrianus) were studied by gross dissection. Based on the configuration of the stomach and the structure of the mucous membrane, the stomach was divided into three ventricles that differ from the arrangement described for ox and sheep. The first and second ventricles of the proventriculus of camel form one stomach rather than two different stomachs. These ventricles of the proventriculus do not correspond to the rumen and reticulum of ox and sheep. The third ventricle appears to be the abomasum. One part of the abomasum has reticular mucosal folds that indicate it is not the reticulum. A second part of the abomasum has longitudinal mucosal folds suggesting it is not the omasum. Three glandular sac areas associated with the preventriculus and abomasum are also described. Copyright 2000 Wiley-Liss, Inc.

A better understanding of gastric accommodation and gastric perception requires knowledge of regional gastric geometry and local gastric tension throughout the stomach. An analytic method based on medical imaging data was developed in this study to describe the three-dimensional (3D) rat stomach geometry and tension distribution. The surface principal radii of curvatures were simulated and the surface tension was calculated in the glandular and non-glandular region of the stomach at pressures from 0 Pa to 800 Pa. The radii of curvature and tension distribution in the stomach were non-homogeneous. The radii of curvature in the glandular stomach were larger than those in the non-glandular region at pressures less than 100 Pa (P < 0.001). When the pressure increased to more than 200 Pa, the radii of curvature in the non-glandular stomach was larger than in the glandular stomach (P < 0.05). The curvature and tension distribution mapping using medical imaging technology and 3D models can be used to characterize and distinguish the physical behaviour in separate regions of the stomach.

Full Text Available History of present illness: A 31-year-old male presented to the emergency department (ED with worsening constant left sided throat pain over the past four months. The patient reports that he was brushing his teeth when his dog jumped onto his back causing his toothbrush to puncture the back of his throat, resulting in immediate bleeding and discomfort. The bleeding subsided and the patient did not seek medical care. The pain radiated to his left ear and the back of the neck. He also noted a change in his voice. The day before presenting to the ED the patient noted subjective fevers, hemoptysis and drooling, which led him to seek medical care. Significant findings: The photograph demonstrates an area of ulcerative tissue at the left palatine tonsil without surrounding erythema or purulent drainage. The computed tomography (CT scan shows a large ulceration of the left soft palate and palatine tonsil (red arrow. There is no evidence of skull base osteomyelitis. There is suppurative lymphadenopathy with partial left jugular vein compression due to mass effect (yellow highlight. There is mild nasopharyngeal airway narrowing with architectural distortion (blue arrow, but no other evidence of airway obstruction. Discussion: The oral cavity is prone to trauma leading to the formation of superficial ulcerations. There are many causes of mechanical trauma, most commonly accidental biting. Chemical, electrical and thermal insults are also possibilities. Poor fitting dental devices and fractured or malformed teeth can also be etiologies.1 Traumatic ulcerations are most common in children given bruxism and thumb sucking. However, a broad differential must be considered including malignant and premalignant lesions, infections of the oral mucosa, aphthous ulcerations and autoimmune diseases.2, 3 Chronic ulcerations are associated with superimposed infection, but there has not been established an association of malignant transformation of the oral mucosa after

Pressure ulcers continue to be a significant problem in hospitals, nursing homes and community care settings. Pressure ulcer incidence is widely accepted as an indicator for the quality of care. Negative attitudes towards pressure ulcer prevention may result in suboptimal preventive care. A reliable and valid instrument to assess attitudes towards pressure ulcer prevention is lacking. Development and psychometric evaluation of the Attitude towards Pressure ulcer Prevention instrument (APuP). Prospective psychometric instrument validation study. A literature review was performed to design the instrument. Content validity was evaluated by nine European pressure ulcer experts and five experts in psychometric instrument validation in a double Delphi procedure. A convenience sample of 258 nurses and 291 nursing students from Belgium and The Netherlands participated in order to evaluate construct validity and stability reliability of the instrument. The data were collected between February and May 2008. A factor analysis indicated the construct of a 13 item instrument in a five factor solution: (1) attitude towards personal competency to prevent pressure ulcers (three items); (2) attitude towards the priority of pressure ulcer prevention (three items); (3) attitude towards the impact of pressure ulcers (three items); (4) attitude towards personal responsibility in pressure ulcer prevention (two items); and (5) attitude towards confidence in the effectiveness of prevention (two items). This five factor solution accounted for 61.4% of the variance in responses related to attitudes towards pressure ulcer prevention. All items demonstrated factor loadings over 0.60. The instrument produced similar results during stability testing [ICC=0.88 (95% CI=0.84-0.91, Ppressure ulcer prevention in patient care, education, and research.

Full Text Available Objective: Pressure ulcer is a chronic wound. It reduces the quality of life of the elderly and individuals with restricted range of motion. It prolongs hospital stay and increases the risk of complications. The cost is quite high. Preventive actions for the prevention of pressure ulcers should be developed. Planning protocols and standards of care are among the main targets. Material and Method: Research was conducted in one-year period between 2012 May and 2013 May on patients who were followed up in Akdeniz University Hospital clinics and intensive care unit with pressure ulcers. The research population consisted of 569 patients. Patient data were recorded in SPSS 16 for Windows program. Statistical analyzes were performed with retrospective methods. The demographic characteristics of patients with pressure ulcers were analyzed as frequency and descriptive statistics. Prevalence and incidence of one year were calculated. Results: Of the patients, 58% were males, 42% were females. Of the patients, 36% were in the age range of 61-80 years, and their average length of stay was 42,9 days. Of the patients, 70% were at stage 2 and 3. In 15% of patients pressure ulcers occurred on the first day of hospitalization. Pressure ulcers were developed between days 2 and 10 in 59% of the patients. Prevalence rate was 2.5%, the incidence was 1.9%, the prevalence rate was 5.9% in the intensive care unit. Conclusion: It is easier to prevent pressure ulcers than treating.

Ulceration corresponds to tissue loss, breaching the muscularis mucosae. When ulcers develop in the acid-peptic environment of the gastroduodenum, they are traditionally called peptic ulcer (PUD). Ulcers never develop spontaneously in a healthy gastroduodenal mucosa. Ulceration is the ultimate

In a study of predation on ground-nesting birds at South San Francisco Bay (South Bay), California, USA, we analyzed stomach contents and stable isotopes of carbon and nitrogen to identify commonly consumed prey. We obtained the stomach contents from 206 nonnative red foxes (Vulpes vulpes regalis) collected in the South Bay area and Monterey County during 1995-2001 and from 68 feral cats (Felis silvestris) from the South Bay area during 2001-2002. We determined prey identity, biomass, and frequency, described seasonal diet trends, and derived an Index of Relative Importance. Avian species were the most frequent prey we found in the stomachs of red foxes from South Bay (61%), whereas small rodents were most frequent for red foxes from Monterey County (62%). Small rodents were the most frequent prey we found in feral cats (63%). Carbon and nitrogen isotopic signatures for foxes supported stomach content findings. However, isotope results indicated that cats received a majority of their energy from a source other than rodents and outside the natural system, which differed from the stomach content analysis. We demonstrated the utility of both stable isotope and stomach content analyses to establish a more complete understanding of predators' diets. This information aids natural resource managers in planning and evaluating future predator-removal programs and increases our understanding of the impacts of nonnative foxes and cats on native species.

Spontaneous esophageal perforation, or Boerhaave's syndrome, is a life-threating condition which usually requires emergent surgery. An upside down stomach is defined as a gastric volvulus in a huge supradiaphragmatic sac. In general, this condition can result in ischemia and perforation of the stomach. This is the first report of a patient with Boerhaave's syndrome and an upside down stomach. A 79-year-old woman presented with sudden epigastric pain following hematemesis. Evaluation of the patient showed both an esophageal perforation and an upside down stomach. Surgical drainage and irrigation of the mediastinum and pleural cavities were undertaken emergently. Due to the concurrent gastric volvulus, a gastrostomy was placed to fix and decompress the stomach. The patient had an uneventful hospital course and was discharged. Boerhaave's syndrome is a rare but severe complication caused by excessive vomiting, due to a sudden elevation in intraluminal esophageal pressure resulting in esophageal perforation. Acute gastric volvulus can result in ischemia and perforation of the stomach, but has not previously been reported with esophageal perforation. The most likely mechanism associating an upside down stomach with Boerhaave's syndrome is acute gastric outlet obstruction resulting in vomiting, and subsequent esophageal perforation. Perforation of the esophagus as well as perforation of the stomach must be considered in patients with an upside down stomach although both upside down stomach and Boerhaave's syndrome are rare clinical entities.

Two male patients who underwent curative surgery and adjuvant radiotherapy (with further chemotherapy in one) for testicular cancer developed adenocarcinoma of the stomach 5 and 19 years after treatment. The stomach is included in the field of radiotherapy used to treat the para-aortic lymph nodes and this may lead to dysplastic changes in the stomach mucosa which can lead to frank malignancy. Early endoscopy should be offered to patients with dyspeptic symptoms after adjuvant radiotherapy for testicular cancer. (author)

Full Text Available Cocoyam (Xanthosoma sagittifolium (L. Schott. tuber is usually consumed as carbohydrates source. Because of highly mineral and fiber contents, it is potential to develop as a functional food source. The mineral contents are potassium, phosphor, magnesium, iron, copper and sodium. Some minerals are well known able to neutralize pH of the gastric fluid. It is necessary to study cocoyam activity on the ulcer gastric. The aims of this study were to determine anti-ulcerogenic activity of cocoyam tuber by observing macroscopic stomach mucous structure on mice and measuring the gastric fluid pH. Twenty male mice aged 2-3 months were used in this study. They were classified in to 4 different treatment groups. Group I was control mice without gastric ulcer, group II, III, and IV were mice with gastric ulcer by using aspirin treatment. Group II,III, and IV were treated with different treatments then for 7 days. Group II was treated by aquadest (negative control group, group III by sucralfat (positive control group, and group IV by cocoyam tuber. In the last treatment day, mice were fasted for 24 hours and then sacrified to pick stomach up. Gastric fluid was collected and the pH was measured then. Stomach mucous structure was observed macroscopically. Data in the gastric fluid pH was analyzed by using one-way ANOVA (Analysis of Variance and continued  HSD (Honest Significant Difference-Tukey test in 5% significance degree. Degree of stomach mucous structure damage was analyzed descriptively and then it was scored based on number and diameter size of ulcers. Data on the ulcer score were analyzed by using Kruskal-Wallis test. The results showed that there was a significant difference (p<0.05 at the stomach fluid pH. Normal group was not significantly different to the sucralfat and cocoyam tuber group, nevertheless normal group was different significantly to the ulcer group. Based on the degree of stomach mucous structure damage, there was not significantly

To investigate the relationship between pressure ulcers of the heel and peripheral arterial disease (PAD) and determine the feasibility of conducting a statistically powered matched case control study. Evidence indicates a relationship between chronic leg ulcers and vascular disease. The relationship between pressure ulcers of the heel and vascular disease is less well established. A matched case control study. Data were collected between March 2014 and January 2015. 15 patients identified as having a grade 2, 3 or 4 pressure ulcer of the heel were compared with 15 matched controls without pressure ulcers of the heel. The primary clinical outcome measure was the ankle brachial pressure index (ABPI), where an ABPI 1.3 was considered clinically indicative of PAD. The primary feasibility outcome measure was the rate of recruitment. Eighty seven patients were reported as having foot and heel ulcers; 36 of whom were identified as having pressure ulcers of the heel, 15 (42%) of whom were recruited to the study. Patients presenting with pressure ulcers of the heel were significantly more likely to simultaneously have previously undiagnosed PAD compared with age, gender and ethnicity matched controls without pressure ulcers of the heel (odds ratio: 11, 95% confidence interval 1.99-60.57). The formation of pressure ulcers of the heel could, in some patients, be related to the presence of PAD rather than a consequence of poor quality care. Healthcare professionals should assess the patient to exclude or confirm PAD. Copyright © 2016 Tissue Viability Society. Published by Elsevier Ltd. All rights reserved.

Spices, herbal xenobiotics and the stomach: friends or foes?

Science.gov (United States)

Spices and herbal remedies have been used since ancient times to treat a variety of disorders. It has been experimentally demonstrated that spices, herbs, and their extracts possess antimicrobial, anti-inflammatory, antirheumatic, lipid-lowering, hepatoprotective, nephroprotective, antimutagenic and anticancer activities, besides their gastroprotective and anti-ulcer activities. Despite a number of reports on the toxicity of herbs and spices, they are generally accepted as safer alternatives to conventional therapy against gastric ulcers. To this end, it is also believed, that excessive consumption of spices may favor the pathogenesis of gastric and duodenal ulcer and some studies have substantiated this common perception. Based on various in vivo experiments and clinical studies, on the effects of spices and herbs on gastric ulcers, it has indeed been shown that certain spices do possess remarkable anti-ulcer properties mediated by antisecretory, cytoprotective, antioxidant, and anti-Helicobacter pylori effects and mechanisms regulated by nitric oxide, prostaglandins, non-protein sulfhydryl molecules and epidermal growth factor expression. Accordingly, their consumption may attenuate and help prevent peptic ulcer disease. In the present review, the beneficial effects of spices and herbal nutritive components on the gastric mucosa are discussed against the paradigm of their deleterious potential.

Prevention of hospital-acquired pressure ulcers requires the implementation of evidence-based interventions. A quality improvement project was conducted to provide nurses with data on the frequency with which pressure ulcer prevention interventions were performed as measured by documentation. Documentation reports provided feedback to stakeholders, triggering reminders and reeducation. Intervention reports and modifications to the documentation system were effective both in increasing the documentation of pressure ulcer prevention interventions and in decreasing the number of avoidable hospital-acquired pressure ulcers.

Using stored serum samples collected from 1970-72 and/or from 1977-79, serum ferritin, transferrin, and ceruloplasmin levels were immunologically determined for 233 stomach cancer and 84 lung cancer cases diagnosed from 1973-83 and for 385 matched controls from a fixed population of Hiroshima and Nagasaki atomic bomb survivors. Elevated stomach cancer risk was associated with low serum ferritin levels, with more than a threefold excess among those in the lowest quintile as compared to the highest ferritin quintile. The average serum ferritin concentration was 8% lower in the stomach cancer cases than in the controls. Risk did not vary with the time between blood collection and stomach cancer onset, remaining high among those with low ferritin levels five or more years before cancer diagnosis. Low ferritin combined with achlorhydria, diagnosed about 10 years before the blood collection and up to 25 years before cancer diagnosis, was an exceptionally strong marker of increased stomach cancer risk. No effect of transferrin or ceruloplasmin independent of ferritin was observed on gastric cancer risk. Lung cancer risk was not related to these three serum proteins. (author)

The morphology of the stomach may vary between species as a function of feeding habits, differences on the cellular composition of the mucosa of the stomach wall and the different functions it carries out. Morphofunctional variations of the stomach of several animals along phylogeny led us to investigate the morphology of the wall of the glandular stomach of rabbits. We used the stomachs of 32 young rabbits (Oryctolagus cuniculus) from the White New Zealand strain, coming from the Experimenta...

Full Text Available Lymphoedema is a progressive condition that can have a marked physical and psychological impact on affected patients and significantly reduce the quality of life. The ulcers on chronic lymphoedema patient, which often also makes it impossible for them to work. If left untreated, tends to progress or worsen. Ulcers in lymphoedema patients, therefore, represent not only a medical but also a psychological problem. The treatment is often regarded as being worse than it actually is. In our study of more than 25 years shows around 10% cases are due to chronic lymphodema. Ulcers of chronic lymphoedema are classified into four stages according to their presentation. Their management depends upon their stage of presentation. Patients with chronic lymphoedema and ulceration require a different approach to treatment. The specific issues associated with managing the patient with lymphoedematous ulceration include, limb shape distortion i.e., elephantiasis, care of the skin creases and folds, and swelling of the toes and fore foot. Stage I ulcers will heal with conservative treatment without any surgical intervention. Stage II ulcers needs debridement of the wound and split-thickness skin grafting. The most difficult to treat are the stage III and IV ulcers, due to associated skin changes and reduced vascularity. These cases need debulking along with excision of the ulcer. In order to prevent recurrence of the ulcer in all the four stages needs prolonged follow-up and limb care.

Full Text Available Abstract Background Guidelines for management of peptic ulcer patients after the treatment are largely directed to detection of H. pylori infection using only non-invasive tests. We compared the diagnostic value of non-invasive and endoscopy based H. pylori tests in a late post-treatment setting. Methods Altogether 34 patients with dyspeptic complaints were referred for gastroscopy 5 years after the treatment of peptic ulcer using a one-week triple therapy scheme. The endoscopic and histologic findings were evaluated according to the Sydney classification. Bacteriological, PCR and cytological investigations and 13C-UBT tests were performed. Results Seventeen patients were defined H. pylori positive by 13C-UBT test, PCR and histological examination. On endoscopy, peptic ulcer persisted in 4 H. pylori positive cases. Among the 6 cases with erosions of the gastric mucosa, only two patients were H. pylori positive. Mucosal atrophy and intestinal metaplasia were revealed both in the H. pylori positive and H. pylori negative cases. Bacteriological examination revealed three clarithromycin resistant H. pylori strains. Cytology failed to prove validity for diagnosing H. pylori in a post-treatment setting. Conclusions In a late post-treatment setting, patients with dyspepsia should not be monitored only by non-invasive investigation methods; it is also justified to use the classical histological evaluation of H. pylori colonisation, PCR and bacteriology as they have shown good concordance with 13C-UBT. Moreover, endoscopy and histological investigation of a gastric biopsy have proved to be the methods with an additional diagnostic value, providing the physician with information about inflammatory, atrophic and metaplastic lesions of the stomach in dyspeptic H. pylori positive and negative patients. Bacteriological methods are suggested for detecting the putative antimicrobial resistance of H. pylori, aimed at successful eradication of infection in

Radioembolization with {sup 90}Y microspheres is a locoregional radiation therapy for unresectable hepatic neoplasm. Non-target delivery of {sup 90}Y microspheres resulting in gastrointestinal (GI) symptoms is a recognized complication; there is minimal knowledge regarding the radiation effect to the gastric wall from left hepatic lobe {sup 90}Y treatments. Our aim was to study the incidence of GI complications when the target tissue (hepatic parenchyma ± tumor) is in close proximity to the gastric wall. We hypothesized that liver (tumor) to stomach proximity does not correlate with increased toxicity. Between November 2011 and September 2013, we studied all patients who underwent left lobe radioembolization with {sup 90}Y glass microspheres. With Institutional Review Board (IRB) approval, we retrospectively reviewed MRI/CT images of these patients, identifying a subset of patients with the left hepatic lobe <1 cm from the gastric wall. Patients were seen in clinic 1 month posttreatment and subsequently at 3-month intervals. Short- and long-term gastric adverse events were tabulated. Ninety-seven patients successfully underwent left hepatic lobe {sup 90}Y microsphere radioembolization in which the average distance from the liver to the stomach wall was 1.0 ± 2.8 mm. The average dose for patients who received radioembolization to the left hepatic lobe was 109 ± 57 Gy. Fifty patients had tumor within 1 cm of the gastric wall. The average dose for patients who received radioembolization to the left hepatic lobe with tumor within 1 cm of the gastric wall was 121 ± 41 Gy. There were no reportable or recordable medical events. Of the patients, 34 % reported abdominal pain that was grade 1-2; 65 % of the patients reported no abdominal pain. None of the 97 patients developed a clinically evident GI ulcer. Patients with left lobe tumors adjacent to or abutting the stomach do not exhibit acute or chronic radiation effects following radioembolization with glass
