    2010-01-01

    The decrease of the cerebral blood flow below the threshold of autoregulation led to changes of cerebral ischemia and necrosis that traduce in signs and symtoms of focal neurologic dysfunction called acute cerebrovascular symdrome (ACS) or stroke. Two big groups according to its etiology are included in this category the hemorragic that constitue a 20% and the ischemic a 80% of cases. Great interest has wom the ischemic ACS because of its high social burden, being the third cause of no violen...

    Fujiwara,Masachika

    1985-02-01

    Full Text Available The clinicopathological findings of cerebral edema were investigated in patients with acute hepatic failure autopsied at Okayama University Hospital between 1970 and 1980 retrospectively. Nine (64% of 14 hepatic failure cases were found to have cerebral edema during a post-mortem examination of the brain. Clinical features of the patients with cerebral edema were not significantly different from those of the patients without cerebral edema. However, general convulsions were observed more frequently in patients later found to have cerebral edema. Moreover, the length of time from deep coma to death was much shorter in the brain edema cases with cerebral herniation than without herniation.

    2008-01-01

    Full Text Available Objective: to study the specific features of purine metabolism in clinically significant acute cerebral ischemia. Subjects and materials. Three hundred and fifty patients with the acutest cerebral ischemic stroke were examined. The parameters of gas and electrolyte composition, acid-base balance, the levels of malonic dialdehyde, adenine, guanine, hypox-anthine, xanthine, and uric acid, and the activity of xanthine oxidase were determined in arterial and venous bloods and spinal fluid. Results. In ischemic stroke, hyperuricemia reflects the severity of cerebral metabolic disturbances, hemodynamic instability, hypercoagulation susceptiility, and the extent of neurological deficit. In ischemic stroke, hyperuri-corachia is accompanied by the higher spinal fluid levels of adenine, guanine, hypoxanthine, and xanthine and it is an indirect indicator of respiratory disorders of central genesis, systemic acidosis, hypercoagulation susceptibility, free radical oxidation activation, the intensity of a stressor response to cerebral ischemia, cerebral metabolic disturbances, the depth of reduced consciousness, and the severity of neurological deficit. Conclusion. The high venous blood activity of xanthine oxidase in ischemic stroke is associated with the better neurological parameters in all follow-up periods, the better early functional outcome, and lower mortality rates. Key words: hyperuricemia, stroke, xanthine oxidase, uric acid, cerebral ischemia.

  5. [Acute benign cerebral angiopathy. 6 cases].

    Rousseaux, P; Scherpereel, B; Bernard, M H; Guyot, J F

    1983-10-08

    The 6 cases reported here constitute, with 5 previously published cases, a special nosological entity tentatively called "acute benign cerebral angiopathy" by the authors. These 11 cases have in common certain radiological and clinical features. Arteriography shows segmental, multifocal and assymetrical stenoses involving the cerebral arteries between Willis' circle and the terminal arterioles and looking like "strings of sausages". The lesions disappear within one month and present the radiological characteristics of arteritis of medium caliber vessels. The clinical symptoms are suggestive of meningeal haemorrhage or acute cerebromeningeal oedema, with acute repetitive attacks of severe headache and agitation with obnubilation; epileptic seizures and transient neurological deficit may occur. True meningeal haemorrhage confirmed by lumbar puncture is seen in nearly one half of the cases; it seems to be due to alterations in the blood-brain barrier induced by the angiopathy. Intracerebral haematoma may develop, but the disease is usually benign and regresses spontaneously in a few days. None of the usual causes of cerebral arteritis (intra-cranial infection, collagen disease, allergic or toxic angitis) has been found. Pseudo-arteritis (notably spasm of ruptured arterial aneurysms) has been excluded. No aetiological factor common to the 11 cases reported has been elicited, although 6 of the patients had recently given birth and our 6 patients had benign virus infection before or during the clinical manifestations of the disease. In the authors' opinion, the most rewarding line of research would be the role of short acute attacks of arterial hypertension.

These results argue against the prevailing hypothesis that adult cytogenesis is reduced in depression and that the common mechanism underlying antidepressant treatments is to increase adult...... cytogenesis. The results also point to the importance of using a disease model and not healthy animals for testing effects of potential treatments for human depression and suggest other cellular mechanisms of action than those that had previously been proposed for escitalopram....

    2016-02-01

    Full Text Available Acute renal failure can cause neurologic manifestations such as mood swings, impaired concentration, tremor, stupor, coma, asterixis, dysarthria. Those findings can also be a sign of cerebral infarct. Here, we report a case of watershed cerebral infarction in a 70-year-old female patient with acute renal failure secondary to contrast administration and use of angiotensin converting enzyme inhibitor. Patient was evaluated with magnetic resonance imaging because of dysarthria. Magnetic resonance imaging revealed milimmetric acute ischemic lesion in the frontal and parietal deep white matter region of both cerebral hemisphere which clearly demonstrated watershed cerebral infarction affecting internal border zone. Her renal function returned to normal levels on fifth day of admission (BUN 32 mg/dl, creatinine 1.36 mg/dl and she was discharged. Dysarthria continued for 20 days.

    Jing Fang; Weihong Yan

    2006-01-01

    BACKGROUND: Comparison of different stroke locations had been focused in past researches in electrocardiogram (ECG) changes of cerebral stroke patients. Some researches neglected the heart disease in the illness history.OBJECTIVE: To discuss ECG changes in different infarction locations and size of acute cerebral infarction and compare with healthy people.DESIGN: Contrast observation.SETrING: Shanghai Ninth People's Hospital.PARTICIPANTS: A total of 57 patients with cerebral infarction were selected from the Neurological Department of Ninth People's Hospital of Shanghai from March 2003 to September 2005. They were diagnosed according to the criteria revised in the 4th National Cerebral Disease Conference and brain images. Patients who had heart disease were excluded. There were 32 males and 25 females, who were 65-84 years old. Among them, 23 cases were involved in right hemisphere, 34 cases in left one, 23 in base ganglion, 11 in brain stem, 9in frontal lobe and 14 in other parts. According to their infarction size (plus size in every different scan), they were divided into three different groups: large-size group (n = 10) with size larger than 3.5 cm3, medium-sizegroup (n = 13) with size between 1.5-3.5 cm3, and small-size group (n = 34) with size smaller than 1.5 cm3.Another 50 healthy subjects were regarded as control group. There were 29 males and 21 females aged 40-82 years. All these cases knew and agreed of the examination.METHODS: Patients received 12-lead ECG examinations within the first 6-24 hours of onset while control group received it at the same time. The HR, PR, QTc, QRS, T wave and ST changes were compared between the two groups.MAIN OUTCOME MEASURES: The ECG changes and differences in two hemispheres, in different infarction lccations and sizes. RESULTS: All 57 patients and 50 healthy subjects were involved in the final analysis. ① ECG changes in infarction group and control group. There were no differences in HR, QRS time and cases with

  13. Diffusion and Perfusion MRI in Acute Cerebral Ischemia

    Tchoyoson CC Lim; Chong-Tin Tan

    2001-01-01

    Reeent advances in magnetic resonance imaging (MRI), in particular diffusion weighted imaging (DWI) and perfusion weighted imaging (PWI), have allowed clinicians to have the ability to differentiate between irreversible cerebral infarction and the potentially reversible ischemic penumbra. This article examines the principles and practice of DWI and PWI. With continued advances in thrombolysis and other therapy for acute cerebral ischemia, neuroimaging is poised to play an increasingly important role in decisionmaking in aeute stroke.

  14. [Hyponatremia in acute intracranial disorders: cerebral salt wasting].

    Betjes, M G; Koopmans, R P

    2000-03-18

    Hyponatraemia is a frequent finding in the course of an acute intracranial disease, especially after a subarachnoid haemorrhage. The fall in plasma sodium concentration is usually mild and not below 124 mmol/l but may reach dangerously low levels with serious neurological complications. In the early 1950s the cause of the hyponatraemia was believed to be primarily excessive natriuresis and therefore named 'cerebral salt wasting'. After the description of the syndrome of inappropriate antidiuretic hormone secretion (SIADH) this was favoured as the most likely explanation. Only in recent years has it become evident that many hyponatraemic patients with acute brain disease are actually hypovolaemic. This is compatible with the original diagnosis of cerebral salt wasting. The increased plasma concentrations of natriuretic peptides are likely to mediate the increased natriuresis. Cerebral salt wasting can be treated with a simple regimen of water and salt suppletion. If needed a mineralocorticoid like fludrocortisone can be given to increase renal tubular sodium reabsorption.

  15. Acute cerebral paragonimiasis presenting as hemorrhagic stroke in a child.

    Chen, Zhi; Zhu, Gang; Lin, Jiangkai; Wu, Nan; Feng, Hua

    2008-08-01

    A hemorrhagic stroke in children is rarely secondary to cerebral paragonimiasis. We describe a 9-year-old boy in whom an intracerebral hemorrhage was the leading clinical indication of acute cerebral paragonimiasis. He was hospitalized because of a sudden onset of headache, right hemiparesis, and dysarthria. A computed tomography scan revealed an intracerebral hemorrhage in the left parietal lobe. Magnetic resonance angiography did not confirm any vascular abnormalities at the location of the hematoma. Four weeks later, he presented with right hemiparesis again, and fever. A diagnosis of cerebral paragonimiasis was based on repeated magnetic resonance imaging of the brain and an enzyme-linked immunosorbent assay for paragonimiasis. The patient gradually recovered with praziquantel treatment. Cerebral paragonimiasis should be considered in the differential diagnosis of hemorrhagic strokes in children in areas where paragonimiasis is epidemic.

  18. Hyponatremia in acute brain disease: the cerebral salt wasting syndrome.

    Betjes, Michiel G.H.

    2002-02-01

    Hyponatremia in acute brain disease is a common occurrence, especially after an aneurysmal subarachnoid hemorrhage. Originally, excessive natriuresis, called cerebral salt wasting, and later the syndrome of inappropriate antidiuretic hormone secretion (SIADH), were considered to be the causes of hyponatremia. In recent years, it has become clear that most of these patients are volume-depleted and have a negative sodium balance, consistent with the original description of cerebral salt wasting. Elevated plasma concentrations of atrial or brain natriuretic peptide have been identified as the putative natriuretic factor. Hyponatremia and volume depletion may aggravate neurological symptoms, and timely treatment with adequate replacement of water and NaCl is essential. The use of fludrocortisone to increase sodium reabsorption by the renal tubules may be an alternative approach.

  19. Difusion weighted imaging characteristics differentiate acute symptomatic cerebral microbleeds from silent microbleeds: An acute pontine microhemorrhage case presentation

    2015-04-01

    Full Text Available Cerebral microbleeds (CMBs on susceptibility weighted imaging (SWI have generally been considered to be silent. Recent reports indicated that, albeit it is a rarity, CMBs can cause acute focal neurological symptoms. Herein we present a patient who was admitted with cheiro-oral syndrome due to an acute izolated pontine microbleed. Combination of diffusion weighted imaging and SWI can be useful in the differentiation of acute symptomatic cerebral microbleeds from chronic ones.

    Full Text Available Abstract Background It is a well-known phenomenon that some patients with acute left or right hemisphere stroke show a deviation of the eyes (Prévost's sign and head to one side. Here we investigated whether both right- and left-sided brain lesions may cause this deviation. Moreover, we studied the relationship between this phenomenon and spatial neglect. In contrast to previous studies, we determined not only the discrete presence or absence of eye deviation with the naked eye through clinical inspection, but actually measured the extent of horizontal eye-in-head and head-on-trunk deviation. In further contrast, measurements were performed early after stroke onset (1.5 days on average. Methods Eye-in-head and head-on-trunk positions were measured at the bedside in 33 patients with acute unilateral left or right cerebral stroke consecutively admitted to our stroke unit. Results Each single patient with spatial neglect and right hemisphere lesion showed a marked deviation of the eyes and the head to the ipsilesional, right side. The average spontaneous gaze position in this group was 46° right, while it was close to the saggital body midline (0° in the groups with acute left- or right-sided stroke but no spatial neglect as well as in healthy subjects. Conclusion A marked horizontal eye and head deviation observed ~1.5 days post-stroke is not a symptom associated with acute cerebral lesions per se, nor is a general symptom of right hemisphere lesions, but rather is specific for stroke patients with spatial neglect. The evaluation of the patient's horizontal eye and head position thus could serve as a brief and easy way helping to diagnose spatial neglect, in addition to the traditional paper-and-pencil tests.

    2015-01-01

    In the clinical setting, bleeding is a common manifestation of acute promyelocytic leukemia (APL), whereas thrombosis is relatively rare, especially as an initial symptom. Here, we report an unusual case of APL with acute myocardial infarction as the first manifestation and cerebral infarction as the relapse manifestation in a healthy young woman. This unique case emphasizes that a thrombotic event could be the first manifestation of an underlying hematological disorder such as APL and could also be a sign of relapse. Rapid detection of the underlying disorder and the timely use of anticoagulation therapy and ATRA are crucial for preventing further deterioration of the disease and saving the patient's life.

    2013-01-01

    Previous investigations suggest that ataxia is common and often one of the most reliable warning signs of high altitude cerebral edema(HACE).The aim of this study was to investigate the diagnostic role of ataxia in acute mountain sickness (AMS) and HACE among mountain rescuers on the quake areas,and in approaching the relation between AMS and HACE.After the earthquake on April 14,2010,approximately 24080 lowland rescuers were rapidly transported from sea level or lowlands to the mountainous rescue sites at 3750 ~ 4568 m,and extremely hardly worked for an emergency treatment after arrival.Assessments of acute altitude illness on the quake areas were using the Lake Louise Scoring System.73 % of the rescuers were found to be developed AMS.The incidence of high altitude pulmonary edema(HAPE) and HACE was 0.73 % and 0.26 %,respectively,on the second to third day at altitude.Ataxia sign was measured by simple tests of coordination including a modified Romberg test.The clinical features of 62 patients with HACE were analyzed.It was found that the most frequent,serious neurological symptoms and signs were altered mental status(50/62,80.6 %)and truncal ataxia (47/62,75.8 %).Mental status change was rated slightly higher than ataxia,but ataxia occurred earlier than mental status change and other symptoms.The earliest sign of ataxia was a vague unsteadiness of gait,which may be present alone in association with or without AMS.Advanced ataxia was correlated with the AMS scores,but mild ataxia did not correlate with AMS scores at altitudes of 3750~4568 m.Of them,14 patients were further examined by computerized tomographic scanning of the brain and cerebral magnetic resonance imagines were examined in another 15 cases.These imaging studies indicated that the presence of the cerebral edema was in 97 % of cases who were clinically diagnosed as HACE (28/29).Ataxia seems to be a reliable sign of advanced AMS or HACE,so does altered mental status.

    Full Text Available The aim is to study the possible impact of some derivatives of gamma-aminobutyric acid (GABA, piracetam, picamilon and Krebs cycle intermediates - succinate (as sodium salt on the pathobiochemical changes in the central nervous system, that occur under experimental playing of acute ischemic tissue damage of the cerebrum.Research methods: The study was conducted in 96 rats Wistar, who were on a standardized vivarium diet. Cerebral ischemia was caused by bond of the unilateral common carotid artery. All drugs were administered intraperitoneally once daily for 4 days after modeling of an acute cerebral ischemia after which animals were withdrawn from experiment. In the brain tissues concentrations of pyruvic, izocitric, dairy and apple acids were determined. The activity of antioxidant enzymes: catalase and superoxide dysmutaza. In addition, the brain tissues the contents of lipid peroxidation products were evaluated – diene conjugates and malonic dialdehyde. Level of brain energy production was judged by the content of the adenylic nucleotide and also phosphocreatine . The degree of destruction of the brain cells was assessed by activity of the enzyme lactate dehydrogenase in the blood and brain fraction of the creatine phosphokinase.Research results: As a result of studies, on the 4th day of ischemia a significant carbohydrate metabolism is detected, which is reflected in the sharp strengthening of anaerobic glycolysis and reduced activity of the Krebs cycle reactions, as evidenced by a significant increase in quantity of lactate and decrease in quantity of malate, isocitrate and pyruvate.A sharp strengthening of anaerobic glycolysis results in the accumulation of oxidized products and intermediates especially the latter product – lactic acid. Metabolic acidosis develops against the background of energy failure, which leads to activation of lipid peroxidation reactions. Courses appointment of the cyclic derivatives of GABA piracetam

    Candelise, L; Roncaglioni, C; Aritzu, E; Ciccone, A; Maggioni, A P

    1996-02-01

    Thrombolysis is proposed for the acute treatment of cerebral infarction as it is able to recanalize occluded arteries and thus potentially restore normal perfusion of the cerebral parenchyma, but the results concerning the efficacy of this treatment are still inconclusive. However, it has been fully demonstrated that thrombolytic treatment, leads to a significant reduction in mortality, in patients with acute myocardial infarction. Data from all of the pilot studies using SK or tPA treatment in acute stroke are described in this review, which underlines the incidence of hemorrhagic transformation (hemorrhagic infart and parenchymal hematoma) and its possible correlation to clinical worsening. Pharmacological, experimental and clinical studies encourage the carrying out of large-scale clinical trials using thrombolytics in patients with acute cerebral infarction. Significant data relating to ongoing controlled clinical trials will be available in the near future; only after the analysis of these results will it be possible to confirm the efficacy of thrombolytics in acute stroke.

    Acute cerebral hemorrhage (ACH) is an important clinical problem that is often monitored and studied with expensive devices such as computed tomography, magnetic resonance imaging, and positron emission tomography. These devices are not readily available in economically underdeveloped regions of the world, emergency departments, and emergency zones. We have developed a less expensive tool for non-contact monitoring of ACH. The system measures the magnetic induction phase shift (MIPS) between the electromagnetic signals on two coils. ACH was induced in 6 experimental rabbits and edema was induced in 4 control rabbits by stereotactic methods, and their intracranial pressure and heart rate were monitored for 1 h. Signals were continuously monitored for up to 1 h at an exciting frequency of 10.7 MHz. Autologous blood was administered to the experimental group, and saline to the control group (1 to 3 mL) by injection of 1-mL every 5 min. The results showed a significant increase in MIPS as a function of the injection volume, but the heart rate was stable. In the experimental (ACH) group, there was a statistically significant positive correlation of the intracranial pressure and MIPS. The change of MIPS was greater in the ACH group than in the control group. This high-sensitivity system could detect a 1-mL change in blood volume. The MIPS was significantly related to the intracranial pressure. This observation suggests that the method could be valuable for detecting early warning signs in emergency medicine and critical care units.

  19. Validation of hyperintense middle cerebral artery sign in acute ischemic stroke

    Gang Guo; Yonggui Yang; Weiqun Yang

    2012-01-01

    We performed a retrospective analysis of non-contrast computed tomography (CT) scans, immediately subsequent magnetic resonance imaging (MRI), and cerebral angiography data from 30 consecutive patients with acute ischemic stroke within 6 hours after symptom onset. Results showed that eleven patients developed subsequent hemorrhagic transformation at follow-up. A hyperintense middle cerebral artery sign on MRI was found in six hemorrhagic patients, all of who had acute thrombosis formation on magnetic resonance angiography and digital subtraction angiography. No patients in the non-hemorrhagic group had hyperintense middle cerebral artery sign on MRI. The sensitivity, specificity, and positive predictive values of the hyperintense middle cerebral artery sign on MRI T1-weighted image for subsequent hemorrhagic transformation were 54.5%, 100%, and 100% respectively. Hyperdense middle cerebral artery sign on non-contrast CT was observed in nine patients, five of who developed hemorrhagic transformation. These data suggest that hyperintense middle cerebral artery sign on MRI T1-weighted image is a highly specific and moderately sensitive indicator of subsequent hemorrhagic transformation in patients after acute ischemic stroke, and its specificity is superior to CT.

    Lim, Ji Kyung; Byun, Woo Mok; Kim, Jae Woon [Yeungnam University College of Medicine, Daegu (Korea, Republic of)

    2011-02-15

    FK506 is widely used as a potent immunosuppressive agent following organ transplantation. However, the use of FK506 is associated with a wide spectrum of neurotoxicity. FK506-induced cerebral infarctions have rarely been reported. We report here on a case of the acute cerebral infarction caused by vasospasm after FK506 administration in a kidney transplantation recipient. There were areas with increased signal intensity on the diffusion-weighted image. The areas showing increased signal intensity on the diffusion- and T2-weighted images demonstrated decreased signal intensity on the apparent diffusion coefficient mapping. MR angiography showed diffuse stenosis in both the anterior and middle cerebral arteries

  1. [Cardioprotective effect of drugs with antioxidant activity in acute cerebral ischemia].

    Stoliarova, V V

    2001-01-01

    The bioelectric cardiac activity was studied in the experiments on white mice with an acute cerebral blood circulation disorder. It was found that he resulting EEG changes possess a specific character, with the sympathoadrenal system stimulation playing an important role in the acute cerebrocardiac syndrome development. The antioxidant-type agents such as emoxypine (50 mg/kg), mexidol (50 mg/kg), and cytochrome C (10 mg/kg) produce a significant cardioprotective effect in the test animals with experimental cerebral ischemia, which was comparable with the effect of propranolol (obsidane) (0.1 mg/kg).

    Ti, L K; Kang, S C; Cheong, K F

    1998-08-01

    A 30-year-old HIV-positive man presented with acute hydrocephalus secondary to tuberculous meningitis, for which an external ventricular drain was inserted. He developed marked natriuresis in the postoperative period, which resulted in acute hyponatraemia (131 to 122 mmol/l) and a contraction of his intravascular volume. A diagnosis of cerebral salt wasting syndrome was made, and he responded to sodium and fluid loading. This case highlights the differentiation of cerebral salt wasting syndrome from the more commonly occurring syndrome of inappropriate anti-diuretic hormone secretion as the aetiology of the hyponatraemia.

    2013-02-15

    A71-year-old man with advanced lung cancer developed a life-threatening cerebral edema caused by the acute occlusion of a superior vena cava (SVC) stent and was successfully treated by an additional stent placement. Although stent occlusion is a common early complication, no life-threatening situations have been reported until now. Our experience highlights the fact that acute stent occlusion can potentially lead to the complete venous shutdown of the SVC, resulting in life-threatening cerebral edema, after SVC stent placement. Immediate diagnosis and countermeasures are required.

  5. Endotoxin has acute and chronic effects on the cerebral circulation of fetal sheep.

    Feng, Susan Y S; Phillips, David J; Stockx, Elaine M; Yu, Victor Y H; Walker, Adrian M

    2009-03-01

    We studied the impact of endotoxemia on cerebral blood flow (CBF), cerebral vascular resistance (CVR), and cerebral oxygen transport (O(2) transport) in fetal sheep. We hypothesized that endotoxemia impairs CBF regulation and O(2) transport, exposing the brain to hypoxic-ischemic injury. Responses to lipopolysaccharide (LPS; 1 microg/kg iv on 3 consecutive days, n = 9) or normal saline (n = 5) were studied. Of LPS-treated fetuses, five survived and four died; in surviving fetuses, transient cerebral vasoconstriction at 0.5 h (DeltaCVR approximately +50%) was followed by vasodilatation maximal at 5-6 h (DeltaCVR approximately -50%) when CBF had increased (approximately +60%) despite reduced ABP (approximately -20%). Decreased CVR and increased CBF persisted 24 h post-LPS and the two subsequent LPS infusions. Cerebral O(2) transport was sustained, although arterial O(2) saturation was reduced (P circulation in two phases: 1) acute vasoconstriction (1 h) and 2) prolonged vasodilatation despite impaired endothelial dilatation (24 h). In surviving fetuses, LPS causes brain injury despite cerebral O(2) transport being maintained by elevated cerebral perfusion; thus sustained O(2) transport does not prevent brain injury in endotoxemia. In contrast, cerebral hypoperfusion and reduced O(2) transport occur in fetuses destined to die, emphasizing the importance of sustaining O(2) transport for survival.

  6. Fluid Intake Related to Brain Edema in Acute Middle Cerebral Artery Infarction.

    Dharmasaroja, Pornpatr A

    2016-02-01

    Evidence of the appropriate amount of fluid intake during the first few days after acute stroke was scarce. Concerns were raised in patients with acute malignant middle cerebral infarction, who tended to have malignant brain edema later. The purpose of the study was to evaluate the effect of fluid intake on the occurrence of malignant brain edema in patients with acute middle cerebral artery infarction. Patients with acute middle cerebral artery infarction who had National Institute of Health Stroke Scale (NIHSS) score of at least 15 were included. Baseline characteristics and amount of fluid intake during the first few days were compared in patients with and without malignant brain edema. One hundred ninety-three patients were studied. Mean NIHSS score was 20. Malignant brain edema occurred in 69 patients (36%). Higher amount of fluid intake (>1650 ml or >28 ml/kg/day or >93% of daily maintenance fluid) showed a significant association with malignant brain edema (OR = 13.86, 95% CI 5.11-37.60, p value edema, 39 patients (39/65, 60%) died and only 11% (7/65 patients) had favorable outcome. High amount of fluid intake in the first few days of acute middle cerebral infarction was related to the occurrence of malignant brain edema.

  7. [Acute epidural hematoma with extravasation on cerebral angiogram in an infant (author's transl)].

    Oseki, J; Oana, K; Kobayashi, T; Kawada, Y; Kanaya, H

    1977-03-01

    The authors recently operated on a boy four years of age with acute epidural hematoma showing an extravasation on the cerebral angiogram. The hematoma (hematoma volume 125 ml) was evacuated 7 hours after the head injury. The postoperative course was quite uneventful, and he was discharged a month after surgery without any neurologic deficits. The authors reviewed the literature and found 4 cases of acute epidural hematoma with extravasations in infants and children. In all cases the operative results were good. The age incidence and frequency of occurence overall for acute epidural hematomas, extravasations on cerebral angiograms and their mechanism, and the length of time from injury to operation were also discussed. It should be emphasized that, for acute epidural hematoma in infants and children, the early diagnosis and early surgery are essential to save the patients.

  12. Acute Headache at Emergency Department: Reversible Cerebral Vasoconstriction Syndrome Complicated by Subarachnoid Haemorrhage and Cerebral Infarction

    M. Yger

    2015-01-01

    Full Text Available Introduction. Reversible cerebral vasoconstriction syndrome is becoming widely accepted as a rare cause of both ischemic and haemorrhagic stroke and should be evocated in case of thunderclap headaches associated with stroke. We present the case of a patient with ischemic stroke associated with cortical subarachnoid haemorrhage (cSAH and reversible diffuse arteries narrowing, leading to the diagnosis of reversible vasoconstriction syndrome. Case Report. A 48-year-old woman came to the emergency department because of an unusual thunderclap headache. The computed tomography of the brain completed by CT-angiography was unremarkable. Eleven days later, she was readmitted because of a left hemianopsia. One day after her admission, she developed a sudden left hemiparesis. The brain MRI showed ischemic lesions in the right frontal and occipital lobe and diffuse cSAH. The angiography showed vasoconstriction of the right anterior cerebral artery and stenosis of both middle cerebral arteries. Nimodipine treatment was initiated and vasoconstriction completely regressed on day 16 after the first headache. Conclusion. Our case shows a severe reversible cerebral vasoconstriction syndrome where both haemorrhagic and ischemic complications were present at the same time. The history we reported shows that reversible cerebral vasoconstriction syndrome is still underrecognized, in particular in general emergency departments.

  13. Meta-analysis of defibrase in treatment of acute cerebral infarction

    2006-01-01

    Background Fibrinogen-depleting agents are promising in the treatment of cerebral ischemic disease. They were studied by many trials, and the outcomes were different because of different regimens and different doses. In this study, we assessed the efficacy and safety of defibrase on acute cerebral infarction in China.Methods A search using Chinese hospital knowledge database (CHKD) and MEDLINE database for randomized controlled trials was carried out. A CHKD (1994 June 2005) search was performed with the keyword "defibrase", then a second search for the keyword "acute cerebral infarction"; a MEDLINE search (1950 June 2005) was performed with the following keywords: [(cerebral ischemia), OR (acute cerebral infarction), OR (stroke)], AND [defibrase]. Meta-analysis was performed with RevMan software 4.2.Results Included were 14 studies comparing the efficiency and safety of defibrase with other drugs in the treatment of acute cerebral infarction. Patients' records were pooled (total 646 patients; defibrase, n=328, no defibrase n=318). Neurological deficit score (NDS) before treatment showed weighted mean differences (WMD)=0.95, 95% confidence interval (CI)= (-0.60, 2.50), P=0.23; NDS after treatment showed WMD=-2.20, 95% CI= (-4.21, -0.18), P=0.03; Barthel index at 3 months showed WMD=4.45, 95% CI= (-0.13, 9.03), P=0.06; the plasma fibrinogen level before treatment showed WMD=0.02, 95% CI= (-0.16, 0.19), P=0.86; plasma fibrinogen level after treatment showed WMD=-1.51, 95% CI= (-1.88, -1.15), P<0.00 001. Conclusions With the given dose and regimen of defibrase in China, defibrase may play a role of anticoagulation. It might inhibit the progression of stroke and prevent the recurrence of stroke.

    Tepmongkol, S. [Nuclear Medicine Division, Department of Radiology, Faculty of Medicine, Chulalongkorn University, Rama IV Road, Bangkok 10330 (Thailand)

    2002-10-01

    The established indication for Tc99m apcitide scintigraphy is for detecting deep venous thrombosis. However, due to its mechanism of binding to GP IIb/IIIa receptors on activated platelets, it can be used to image acute cerebral thrombosis. I report a patient with an acute ischaemic stroke, with right leg swelling, referred for Tc99m apcitide scintigraphy to show of deep venous thrombosis. There was no abnormal uptake in the legs but there was in the left parieto-occipital region. This correlated with the clinical and CT data, indicating an acute ischaemic stroke in this area. (orig.)

    2016-01-01

    Objective:To investigate the changes of serum inflammatory factors and hemodynamics in patients with acute cerebral infarction and its clinical significance.Methods: A total of 55 cases of acute cerebral infarction (ACI) patients as observation group, and cases of healthy physical examination were selected as the observation group, and 55 healthy persons as control group. ELISA method was used to detect inflammatory cytokines interleukin-6 (IL-6), interleukin-8 (IL-8), C-reactive protein (CRP) and tumor necrosis factor (TNF-α) level, WA-880 heart and brain integrated digital hemodynamic monitor to detect bilateral carotid artery blood flow velocity, blood flow and peripheral resistance.Results:The serum levels of IL-8, CRP, IL-6 and TNF-α were higher in the observation group than in the control group, the difference was statistically significant (P<0.05). The blood flow velocity and blood flow velocity in the observation group were significantly lower than those in the control group. The difference was statistically significant (IL-8). With the increase of infarct size, serum IL-6, CRP,P<0.05 and TNF-α increased significantly (P<0.05).Conclusions:The changes of serum inflammatory factors and hemodynamic indexes can be used to judge the early cerebral infarction and the size of the infarct size of the index, the clinical dynamic monitoring of its changes in patients with acute cerebral infarction and the severity of the prognosis and the prognosis of the important significance of the judgment.

  19. Morphology of platelet Golgi apparatus and their significance after acute cerebral infarction.

    Lu, Wei; Xu, Dong; Tu, Ranran; Hu, Zhiping

    2013-08-15

    Blood samples were harvested from the antecubital vein of 20 fasting patients with acute cerebral infarction at 1, 7 and 15 days after onset to prepare blood platelet suspension. Fasting antecubital vein blood was collected from an additional 20 normal adults as controls. Under transmission tron microscope, platelet Golgi tubules and vesicles became significantly thickened, enlarged, and irregular after acute cerebral infarction. Alpha granules in platelets significantly reduced in number, especially 1 day after cerebral infarction. Under immunoelectron microscopy, a few alpha granules aggregated around Golgi tubules and vesicles after infarction. These results suggested that platelet Golgi apparatus displayed significant morphological changes, which were possibly associated with enhanced synthetic and secretory functions of activated platelets after acute cerebral infarction. This study used Golgi apparatus blocking agent Brefeldin A to block Golgi apparatus in an aim to study the effects of Golgi apparatus on CD40L expression on the surface of activated platelets. Flow cytometry revealed that CD40L expression on activated platelet surfaces decreased significantly when Golgi apparatus was blocked, which indicated that Golgi apparatus participated in the synthesis and transport of CD40L to the platelet surface.

  1. Bacillus cereus Cerebral Abscess During Induction Chemotherapy for Childhood Acute Leukemia.

    Dabscheck, Gabriel; Silverman, Lewis; Ullrich, Nicole J

    2015-10-01

    A 5-year-old boy with standard-risk B-cell acute lymphoblastic anemia developed fever during induction chemotherapy. The patient had no neurological symptoms. Blood cultures grew Bacillus cereus and neuroimaging studies demonstrated a cerebral abscess. Imaging changes resolved after completion of antibiotics. Bacillus cereus bacteremia is increasingly implicated as the cause of life-threatening infections, including cerebral abscesses, in compromised patients. Positive blood cultures for this organism should prompt neuroimaging and consideration of cerebrospinal fluid sampling, as well as catheter removal. Given the worse outcome with central nervous system involvement, there is a need for increased awareness and early diagnosis, particularly in immunocompromised individuals.

    2006-10-01

    The purpose of this investigation was to describe the causes, clinical pattern, and treatment of cerebral salt wasting syndrome in children with acute central nervous system injury. This retrospective study focused on patientscerebral salt wasting syndrome, over a period of 7 years, in the pediatric intensive care unit of a tertiary care hospital. Selection criteria included evidence of hyponatremia (serum sodium120 mEq/L), and volume depletion. Fourteen patients were identified with cerebral salt wasting syndrome, 12 after a neurosurgical procedure (8 brain tumor, 4 hydrocephalus) and 2 after severe brain trauma. In 11 patients the cerebral salt wasting syndrome was diagnosed during the first 48 hours of admission. Prevalence of cerebral salt wasting syndrome in neurosurgical children was 11.3/1000 surgical procedures. The minimum sodium was 122+/-7 mEq/L, the maximum urine osmolarity 644+/-59 mOsm/kgH2O. The maximum sodium supply was 1 mEq/kg/h (range, 0.1-2.4). The mean duration of cerebral salt wasting syndrome was 6+/-5 days (range 1-9). In conclusion, cerebral salt wasting syndrome can complicate the postoperative course of children with brain injury; it is frequently present after surgery for brain tumors and hydrocephalus and in patients with severe head trauma. Close monitoring of salt and fluid balance is essential to prevent severe neurologic and hemodynamic complications.

    2005-01-01

    Objective: To investigate the time course of serum S-100 concentrations of patients with acute cerebral infarction,and their relation with the clinical data and the prognosis. Methods: Serum S-100 levels were serially determined in 35 patients with acute cerebral infarction within 12 h, at 24 h and day 2, 3, 4, 5,7 and 10 after acute cerebral infarction and in 20 age- and sex-matched control subjects. An S-100 content assay was performed using a two-site radioimmunoassay technique. The clinical status was assessed using NIH Stroke Scale. The functional deficit at 4 weeks after acute cerebral infarction was scored using the modified Rankin scale. A cranial computed tomography was performed initially. Results: Elevated concentrations of S100 (>0.2 μg/L) were observed in 29 of 36 patients with acute cerebral infarction,but none of the control subjects. The S-100 peak levels were at day 2 and 3 after acute cerebral infarction and were significantly high in those patients with severe neurological deficit at admission, with extensive infarction or with space-occupying effect of ischemic edema as compared with the rest of the populations. Conclusion: Serum S-100 level assay can be used as a peripheral marker of ischemic brain damage, and may be helpful for evaluation of therapeutic effects in acute ischemic stroke.

    In most of the 129 patients with a recent stroke by cerebral hemorrhage or infarction a note-worthy acute-phase response was found, as demonstrated by important quantitative alterations of blood levels of several acute-phase proteins (APP). These alterations were different in patients with cerebral hemorrhage as compared to those with cerebral infarction. The alterations due to cerebral infarction were not different according to the site of the infarction in brain, i.e. in the brain territories irrigated by the carotid artery system or by the basilar artery system. The APP alterations do not depend on the sex of patients or on the time elapsed from stroke-onset to blood collection.

  5. Acute functional deterioration in a child with cerebral palsy.

    Smyth, Elizabeth

    2012-01-01

    We describe a case of acute functional deterioration in a 13-year-old girl with severe spastic diplegia (GMFCS III) and a new diagnosis of diffuse intrinsic pontine glioma (DIPG). She presented with acute deterioration in mobility and motor function over 1 month, which was associated with dysarthria, dysphagia and behavioural change. Her mother had noticed subtle functional deterioration over the 2 months prior to this. Her physiotherapist who was concerned about her acute functional deterioration referred her for emergency review. Neurological imaging revealed a diffuse pontine lesion consistent with DIPG. She was subsequently referred to oncology. She deteriorated further, clinically, over the next few days and following discussion with the team; her family opted for palliative treatment, given the poor prognosis associated with DIPG.

    that follows reperfusion. The amount of lactate present in the acute phase reflects the severity of ischemia in the affected region. The lactate level was still above normal in the subacute phase with hyperemia, suggesting lactate production through aerobic glycolysis. Thus, the lactate level in the subacute...... phase probably does not reflect the degree of anaerobic glycolysis in hypoxic neuronal tissue....

    BACKGROUND: Thrombomodulin concentration greatly increases in plasma when vascular endothelial cells are injured, and it is one of the specific molecular markers for endothelial injury.OBJECTIVE: To analyze the plasma levels of thrombomodulin after cerebral infarction or hypertension, and to compare levels with those from healthy control subjects.DESIGN: A case-controlled observation. SETTING: Yuquan Hospital of Tsinghua University.PARTICIPANTS: Patients with hypertension (n = 37) and acute cerebral infarction (n = 26) were selected from the outpatient and inpatient Department of Neurology, Yuquan Hospital of Tsinghua University from February 2003 to February 2006. The cerebral infarction group consisted of 24 males and 2 females, 36–77 years of age, with a mean age of 62 years. All patients fulfilled the diagnosis criteria for cerebral infarction, according to the diagnostic standards revised by the Second National Academic Meeting for Cerebrovascular Disease, and were confirmed by CT or MRI. The hypertension group consisted of 27 males and 10 females, 36–77 years of age, with a mean age of 56 years. These patients fulfilled the diagnostic criteria for hypertension set by WHO. In addition, 43 healthy physical examinees were selected as the control group, consisting of 23 males and 20 females, 35–67 years of age.Informed consent was obtained from all participants.METHODS: In the cerebral infarction group, thrombomodulin plasma levels were determined by enzyme-linked immunoabsorbent assay at days 1, 3, 7, and 14 after attack. Thrombomodulin plasma levels were determined only once in the hypertension group and the control group. The results from the cerebral infarction group were compared with those from the hypertension group and the control group. MAIN OUTCOME MEASURES: Level of thrombomodulin in plasma.RESULTS: All 63 patients and 43 healthy volunteers were included in the final analysis of results. ① At 7 days after the attack, the plasma levels of

  8. Study on the Relationship between Plasma Homocysteine and Acute Cerebral Vascular Disease

    2000-01-01

    The levels of plasma homocysteine were determined by using high-performance liquid chromatographic method. It was found that plasma homocysteine levels were significantly higher in the patients with stroke than that in the controls. There was no correlation between plasma homocysteine levels and hypertension, smoking, concentrations of blood glucose or hypertriglyceridesemia. It was suggested that hyperhomocysteinemia may be an independent risk factor for acute cerebral vascular disease.

    Isolated left ventricular noncompaction in adults is uncommon. The most frequent clinical manifestations are heart failure due to left ventricular systolic dysfunction and supraventricular and ventricular arrhythmias, which may be sustained and associated with sudden death. Thromboembolic complications are also possible. We report the case of an adult patient with isolated left ventricular noncompaction who came to our observation because of acute cerebral ischemia, an initial presentation of the disease only rarely described.

    2002-01-01

    The purpose of this study was to test the hypothesis that regional brain blood flow and vascular resistance are altered by acute and chronic head-down tail suspension (HDT). Regional cerebral blood flow, arterial pressure, heart rate, and vascular resistance were measured in a group of control rats during normal standing and following 10 min of HDT and in two other groups of rats after 7 and 28 days of HDT. Heart rate was not different among conditions, whereas mean arterial pressure was elevated at 10 min of HDT relative to the other conditions. Total brain blood flow was reduced from that during standing by 48, 24, and 27% following 10 min and 7 and 28 days of HDT, respectively. Regional blood flows to all cerebral tissues and the eyes were reduced with 10 min of HDT and remained lower in the eye, olfactory bulbs, left and right cerebrum, thalamic region, and the midbrain with 7 and 28 days of HDT. Total brain vascular resistance was 116, 44, and 38% greater following 10 min and 7 and 28 days of HDT, respectively, relative to that during control standing. Vascular resistance was elevated in all cerebral regions with 10 min of HDT and remained higher than control levels in most brain regions. These results demonstrate that HDT results in chronic elevations in total and regional cerebral vascular resistance, and this may be the underlying stimulus for the HDT-induced smooth muscle hypertrophy of cerebral resistance arteries.

    2016-01-01

    Full Text Available Background. Cerebral hyperperfusion syndrome (CHS, a rare complication after cerebral revascularization, is a well-described phenomenon after carotid endarterectomy or carotid artery stenting. However, the imaging evidence of CHS after intravenous tissue plasminogen activator (iv tPA for acute ischemic stroke (AIS has not been reported. Case Report. Four patients were determined to have manifestations of CHS with clinical deterioration after treatment with iv tPA, including one patient who developed seizure, one patient who had a deviation of the eyes toward lesion with worsened mental status, and two patients who developed worsened hemiparesis. In all four patients, postthrombolysis head CT examinations were negative for hemorrhage; CT angiogram showed patent cervical and intracranial arterial vasculature; CT perfusion imaging revealed hyperperfusion with increased relative cerebral blood flow and relative cerebral blood volume and decreased mean transit time along with decreased time to peak in the clinically related artery territory. Vascular dilation was also noted in three of these four cases. Conclusions. CHS should be considered in patients with clinical deterioration after iv tPA and imaging negative for hemorrhage. Cerebral angiogram and perfusion studies can be useful in diagnosing CHS thereby helping with further management.

    1988-08-01

    We report two cases, one of acute cerebral swelling and the other with a major stroke, whose MRI has shown very interesting findings. Case 1, a 32-year-old male, was admitted to our service because of a lowering of his consciousness immediately after a head injury. On admission, the patient was semicomatous (E/sub 1/M/sub 2/V/sub 1/, with anisocoria (R > L). His plain skull X-ray was normal. A CT scan, however, demonstrated right isodensity hemispheric swelling associated with a subarachnoid hemorrhage in the right Sylvian fissure. A right carotid angiogram showed no vascular disorders. MR imaging of the spin density demonstrated a hyperintensitive thickening of the gray matter in the whole right hemisphere. Case 2, a 58-year-old female, was admitted because of a sudden onset of loss of consciousness, with right hemiparesis and dysarthria. On admission, her consciousness was semicomatous (E/sub 1/M/sub 3/V/sub 1/), and it deteriorated to a deep coma 1 hour later. A CT scan demonstrated a diffuse left hemispheric low density, with a finding of hemorrhagic infarction in the basal ganglia. MR imaging of the spin density showed a hyperintensitive thickening of the gray matter resembling that of Case 1. The findings of the spin-echo images of our two cases showed a hyperintensitive thickening of the gray matter in both. The hyperintensity and thickening of the gray matter apparently indicated a sort of hyperemia and brain edema. These findings led us to suspect that the hyperemia associated with acute cerebral swelling and ischemic brain edema of our two cases originated in the gray matter, although it has been considered that the pathogenesis of acute cerebral swelling is not known and that brain edema, especially vasogenic edema, will mostly develop in the white matter rather than in the gray matter.

    The aims of this study were to observe magnetic resonance imaging (MRI) features and the frequency of hemorrhagic transformation (HT) in patients with acute cerebral infarction and to identify the risk factors of HT. We first performed multimodal MRI (anatomical, diffusion weighted, and susceptibility weighted) scans on 87 patients with acute cerebral infarction within 24 hours after symptom onset and documented the image findings. We then performed follow-up examinations 3 days to 2 weeks after the onset or whenever the conditions of the patients worsened within 3 days. We utilized univariate statistics to identify the correlations between HT and image features and used multivariate logistical regression to correct for confounding factors to determine relevant independent image features of HT. HT was observed in 17 out of total 87 patients (19.5 %). The infarct size (p = 0.021), cerebral microbleeds (CMBs) (p = 0.004), relative apparent diffusion (rADC) (p = 0.023), and venous anomalies (p = 0.000) were significantly related with HT in the univariate statistics. Multivariate analysis demonstrated that CMBs (odd ratio (OR) = 0.082; 95 % confidence interval (CI) = 0.011-0.597; p = 0.014), rADC (OR = 0.000; 95 % CI = 0.000-0.692; p = 0.041), and venous anomalies (OR = 0.066; 95 % CI = 0.011-0.403; p = 0.003) were independent risk factors for HT. The frequency of HT is 19.5 % in this study. CMBs, rADC, and venous anomalies are independent risk factors for HT of acute cerebral infarction. (orig.)

  19. The Longitudinal Evolution of Cerebral Blood Flow Regulation after Acute Ischaemic Stroke

    2014-08-01

    Full Text Available Background: Acute stroke is known to impair cerebral blood flow (CBF regulation, but the longitudinal changes of these effects have been poorly reported. The main CBF regulatory mechanisms [cerebral autoregulation (CA and neurovascular coupling (NVC] were assessed over 3 months after acute ischaemic stroke. Methods: Recordings of CBF velocity (CBFv, blood pressure (BP, and end-tidal CO2 were performed during 5 min baseline and 1 min passive movement of the elbow. Stroke patients were assessed Results: Fifteen acute stroke subjects underwent all 4 sessions and were compared to 22 control subjects. Baseline recordings revealed a significantly lower CBFv in the affected hemisphere within 72 h after stroke compared to controls (p = 0.02 and a reduction in CA index most marked at 2 weeks (p = 0.009. CBFv rise in response to passive arm movement was decreased bilaterally after stroke, particularly in the affected hemisphere (p Conclusion: The major novel finding of this study was that both CA and NVC regulatory mechanisms deteriorated initially following stroke onset, but returned to control levels during the recovery period. These findings are relevant to guide the timing of interventions to manipulate BP and potentially for the impact of intensive rehabilitation strategies that may precipitate acute physiological perturbations but require further exploration in a larger population that better reflects the heterogeneity of stroke. Further, they will also enable the potential influence of stroke subtype to be investigated.

  20. Metabolism of biogenic amines in acute cerebral ischemia: Influence of systemic hyperglycemia

    Milovanović Aleksandar

    2012-01-01

    Full Text Available Dopamine, norepinephrine and serotonin are biogenic amines which are transmitters of the central nervous system. The effects of ischemia on the brain parenchyma depends on many factors, such is the mechanism of blood flow interruption, velocity of the occurring blood flow interruption, duration of an ischemic episode, organization of anatomical structures of the brain blood vessels etc., which all influence the final outcome. During interruption of the brain circulation in experimental or clinical conditions, neurotransmitter metabolism, primarily of biogenic amines, is disturbed. Many researches with various experimental models of complete ischemia reported a decrease in the content of norepinephrine, dopamine and serotonin in the CNS tissue. It was proven that hyperglycemia can drastically increase cerebral injury followed by short-term cerebral ischemia. Considering the fact that biogenic amines (dopamine, norepinephrine and serotonin influence the size of neurologic damage, as well as the fact that in hyperglycemic conditions infarct size (from the morphological aspect is larger relative to normoglycemic status, the intention was to evaluate the role of biogenic amines in occurrence of damage in conditions of hyperglycemia, i.e. in the case of brain apoplexia in diabetics. Analysis of biogenic amines metabolism in states of acute hyperglycemia, as well as analysis of the effects of reversible and irreversible brain ischemia on metabolism of serotonin, dopamine and norepinephrine, showed that acute hyperglycemia slows down serotonin, dopamine and norepinephrine metabolism in the cerebral cortex and n. caudatus. Brain ischemia in normoglycemic animals by itself has no influence on biogenic amines metabolism, but the effect of ischemia becomes apparent during reperfusion. In recirculation, which corresponds to the occurrences in penumbra, release of biogenic amines is uncontrolled and increased. Brain ischemia in acute hyperglycemic animals

    Full Text Available Electroacupuncture (EA is a novel therapy based on traditional acupuncture combined with modern eletrotherapy that is currently being investigated as a treatment for acute ischemic stroke. Here, we studied whether acute EA stimulation improves tissue and functional outcome following experimentally induced cerebral ischemia in mice. We hypothesized that endothelial nitric oxide synthase (eNOS-mediated perfusion augmentation was related to the beneficial effects of EA by interventions in acute ischemic injury. EA stimulation at Baihui (GV20 and Dazhui (GV14 increased cerebral perfusion in the cerebral cortex, which was suppressed in eNOS KO, but there was no mean arterial blood pressure (MABP response. The increased perfusion elicited by EA were completely abolished by a muscarinic acetylcholine receptor (mAChR blocker (atropine, but not a β-adrenergic receptor blocker (propranolol, an α-adrenergic receptor blocker (phentolamine, or a nicotinic acetylcholine receptor (nAChR blocker (mecamylamine. In addition, EA increased acetylcholine (ACh release and mAChR M3 expression in the cerebral cortex. Acute EA stimulation after occlusion significantly reduced infarct volume by 34.5% when compared to a control group of mice at 24 h after 60 min-middle cerebral artery occlusion (MCAO (moderate ischemic injury, but not 90-min MCAO (severe ischemic injury. Furthermore, the impact of EA on moderate ischemic injury was totally abolished in eNOS KO. Consistent with a smaller infarct size, acute EA stimulation led to prominent improvement of neurological function and vestibule-motor function. Our results suggest that acute EA stimulation after moderate focal cerebral ischemia, but not severe ischemia improves tissue and functional recovery and ACh/eNOS-mediated perfusion augmentation might be related to these beneficial effects of EA by interventions in acute ischemic injury.

    Objective: To detect the levels of dipalmitoyl phosphatidyl choline (DPPC) in the sputum of the patients with acute cerebral injury without primary pulmonary injury after mechanical ventilation treatment.Methods: DPPC levels in sputum of 35 patients with acute cerebral injury but without pulmonary injury were detected with high performance liquid chromatography at the beginning of ventilation and 16-20 days, 21-40 days,and 41-60 days after ventilation, respectively.Results: There was no significant difference of the DPPC levels between 16-20 days after ventilation (3.36 ±0.49) and at the beginning of ventilation ( 3.37 ± 0.58 )(P>0.05). The mean levels of DPPC decreased significantly at 21-40 days (2.87 mg/ml ±0.26 mg/ml, P <0.05) and 41-60 days (1.93 mg/ml ±0.21 mg/ml, P <0.01) after ventilation compared with that at the beginning of ventilation. At the same period, the peak inspiratory pressure and the mean pressure of airway increas ed significantly, whereas the static compliance and the partial pressure of oxygen in artery decreased significantly. Among the 25 patients who received ventilation for more than 20days, 8 (32%) had slightly-decreased partial pressure of oxygen in artery compared with that at the beginning of ventilation.Conclusions: Mechanical ventilation can decrease the DPPC levels, decrease the lung compliance and increase the airway pressure, even impair the oxygenation function in patients with acute cerebral injury. Abnormal DPPC is one of the major causes of ventilator-associated lung injury.

    Objective: To investigate the early changes and clinical significance of plasma endothelin (ET), nitric oxide (NO) and arginine-vasopressin (AVP) in patients with acute moderate or severe cerebral injury. Methods: The early (at 24 hours after injury) plasma concentrations of ET, NO and AVP were measured with radioimmunoassay and Green technique in 48 cases of acute moderate (GCS≤8 in 27cases ) or severe (GCS>8 in 21 cases) cerebral injury (Group A), in 42 cases of non-cerebral injury (Group B) and in 38 normal individuals (Group C), respectively. Results: The early plasma concentrations of ET (109.73 ng/L±12.61 ng/L), NO (92.82 μmol/L±18.21 μmol/L) and AVP (49.78 ng/L±14.29 ng/L) in Group A were higher than those in Group B (67.90 ng/L±11.33 ng/L, 52.66 μmol/L±12.82 μmol/L and 29.93 ng/L±12.11 ng/L, respectively, P<0.01) and Group C (50.65 ng/L±17.12 ng/L, 36.12 μmol/L±12.16 μmol/L and 5.18 ng/L±4.18 ng/L, respectively, P<0.001). The amounts of ET, NO and AVP in patients with severe cerebral injury were 116.18 ng/L±18.12 ng/L, 108.19 μmol/L±13.28 μmol/L and 58.13 ng/L±16.78 ng/L, respectively, which were significantly higher than that of the patients with moderate cerebral injury (92.33 ng/L±16.32 ng/L, 76.38 μmol/L±12.71 μmol/L and 36.18 ng/L±12.13 ng/L respectively, P<0.01). The early levels of ET, NO and AVP in Group A were negatively related to the GCS scales. The amounts of ET, NO and AVP were 126.23 ng/L±15.23 ng/L, 118.18 μmol/L±10.12 μmol/L and 63.49 ng/L±14.36 ng/L respectively in patients with subdural hematoma, which were significantly higher than those in patients with epidural hematoma (81.13 ng/L±12.37 ng/L, 68.02 μmol/L±13.18 μmol/L and 45.63 ng/L±12.41 ng/L respectively, P<0.01). The plasma concentrations of ET, NO and AVP in stable duration (at 336 hours after injury) in Group A and Group B were similar to those in Group C.Conclusions: ET, NO and AVP were related to the pathophysiological process that occurs in

This study aimed to determine the cerebrolysin impact on the neurological outcomes and cerebral blood flow. Methods: In a randomized, double-blinded, placebo-controlled trial, 46 patients who had acute focal ischemic stroke were randomly assigned into two groups to receive intravenously either 30 mL of cerebrolysin diluted in normal saline daily for 10 days (n=23 or normal saline alone (n=23 adjunct to 100 mg of aspirin daily. All patients were examined using the National Institutes of Health Stroke Scale and transcranial Doppler to measure the mean flow velocity and pulsatility index (PI of their cerebral arteries at baseline as well as on days 30, 60, and 90. Results: The patients’ mean age was 60±9.7 years, and 51.2% of patients were male. The National Institutes of Health Stroke Scale was significantly lower in the cerebrolysin group compared with the placebo group on day 60 (median 10, interquartile range 9–11, P=0.008 and day 90 (median 11, interquartile range 10–13.5, P=0.001. The median of PI in the right middle cerebral artery was significantly lower in the cerebrolysin group compared with the placebo group on days 30, 60, and 90 (P<0.05. One patient in the cerebrolysin group and two patients in the placebo group died before day 30 (4.3% versus 8.7%. Conclusion: Cerebrolysin can be useful to improve the neurological outcomes and the PI of middle cerebral artery in patients with acute focal ischemic stroke.

    2003-01-01

    Objective To determine the distribution of aortic arch and intra/extracranial cerebral arterial atherosclerosis in Chinese patients who had suffered acute ischemic strokes. Methods Eighty-nine patients with acute ischemic strokes were included in this study. Transesophageal echocardiography (TEE) was used to evaluate potential sources of embolisms in the aortic arch and in the heart; duplex ultrasound was used for the carotid artery; and intracranial Doppler (TCD) imaging was used for the middle cerebral artery (MCA), anterior cerebral artery (ACA), posterior cerebral artery (PCA), and basilar artery (BA). An atherosclerotic lesion in the aortic arch was defined as normal (0); mild plaque (1); moderate plaque (2); and protruding plaque or mobile plaque (3). A lesion in the carotid artery was considered a plaque if the maximal carotid plaque thickness was 1.2 mm. TCD results were deemed abnormal if flow velocity was either greater or lower than normal, and, in the case of the MCA, if an asymmetry index above 21% was measured. Results Of the 89 patients, 52 (58.43%) patients showed evidence of aortic arch atherosclerosis (AAA), including 11 (12.36%) patients graded mild, 18 (20.22%) patients graded moderate, and 23 (25.84%) patients graded severe. Of the 23 patients with severe AAA, AAA was determined to be an important potential embolic source in 14 patients. Forty-nine (50.56%) patients had carotid arterial plaques (CAPs). The incidence of carotid plaques was higher among patients with AAA than among patients without AAA (71.15% vs 21.62%, OR=3.291, 95% CI=1.740-6.225, P<0.001). TCD abnormalities affecting the MCA were found in 54 (60.67%) patients. Differences in incidence of TCD abnormalities between patients with AAA and without AAA (69.23% vs 48.65%) were not significant (OR=1.423, 95% CI=0.976-2.076, P=0.05). There was a higher incidence of AAA in older, male patients with a history of diabetes and smoking. Conclusions AAA is an important potential source of

    In the present paper, the authors review recent advances in clinical and experimental studies on acupuncture treatment of cerebral hemorrhage(CH). Regarding clinical studies, the resuscitation-inducing needling maneuver, and main points of Shuigou(水沟GV 26),Baihui(百会 GV 20) and scalp-points Motor Area(MS 6), Sensory Area(MS 7), etc. are often involved. Concerning experimental studies, the underlying mechanisms of acupuncture of GV-26+"Neiguan"(内关 PC 6), GV-20,GV-26+GV-20, etc. in improving acute CH are introduced. In a word, acupuncture therapy works well in improving clinical symptoms and signs of CH patients, and acupuncture stimulation induced ameilioration of cerebral blood flow, favorable modulation of some bioactive substances as excitatory and inhibitory amino acids, endothelin, CGRP, heat shock protein 70, etc. and neuro-endocrine-immune network may contribute to the effect of acupuncture on CH. In addition, acupuncture combined with medicine and earlier application of acupuncture therapy in the acute stage of CH are recommended in clinical practice.

    BACKGROUND: Hyperbaric oxygen (HBO) therapy increases blood oxygen content, changes cerebral blood flow (CBF) and cerebral metabolism. Its therapeutic effects on cerebrovascular disease have been fully confirmed, but the occasion for HBO therapy is still unclear.OBJECTIVE: To observe the therapeutic effects of HBO therapy at different time on CBF and electroencephalogram (EEG) in patients with acute cerebral infarction (CI).DESIGN: Randomized controlled trial.SETTING: Department of Neurology, Shidong Hospital, Yangpu District of Shanghai.PARTICIPANTS: Ninety-six inpatients with acute CI, admitted to Department of Neurology, Shidong Hospital, Yangpu District of Shanghai from January 2001 to December 2006, were involved in this experiment. The involved participants met the diagnosis criteria of acute CI and confirmed by skull CT or MRI. They all were patients with moderate CI (16- 30 points) according to neurologic deficit score formulated by Chinese Medical Association. Informed consents of detected items and therapeutic regimen were obtained from all the involved participants. They were randomized into two groups with 48 in each:early-stage treatment group and advanced-stage treatment group. Among the 48 patients in the early-stage treatment group, 21 male and 27 female, aged 53 -68 years, 22 patients were found with basal ganglia infarction, 10 with brain lobe infarction, 16 with multiple infarction, 27 accompanied with hypertension and 2 accompanied with diabetes mellitus. Among the 48 patients in the advanced-stage treatment group, 23 male and 25 female, aged 52 - 71 years, 25 patients were found with basal ganglia infarction, 10 with brain lobe infarction, 12 with multiple infarction, 1 with brain stem infarction, 28 accompanied with hypertension and 1 accompanied with diabetes mellitus.METHODS: After admission, patients of two groups received routine drug treatment. ① Patients in the early-stage treatment group and advanced-stage treatment group began to

    1988-01-01

    A 34-year-old woman presented with urination difficulty and consciousness disturbance, followed by persistent neurologic findings, such as semicomatose mental status and bilateral optic neuritis, and monophasic clinical course. Cranial CT showed multifocal low density areas in cerebral white matter. The patient was clinically diagnosed as having acute disseminated encephalomyelitis. She died of sepsis four months later. Autopsy revealed multifocal large demyelinating lesions confined to the cerebral white matter, shown as low density areas on CT scans, and demyelinating plaques scattered in the optic nerves and chiasm, and cerebral peduncle. The final diagnosis was acute multiple sclerosis. The CT appearance of multifocal low density areas was most likely due to demyelinating lesions causing edema and tissue necrosis. (Namekawa, K.).

    The purpose of this study is to confirm the diagnosis of acute cerebral infarction on diffusion-weighted imaging using low field (0.2 T) magnetic resonance image (MRI). Acute cerebral infarctions in 51 patients were examined on diffusion-weighted imaging using low field MRI within 48 hours after clinical symptoms. Diffusion-weighted imaging was examined using line scan method. Twenty-four cases were cortical infarction, and twenty-two cases were perforating infarction. In five cases out of 51 cases, ischemic regions were not detected as abnormal high signal intensity area on diffusion-weighted imaging. Four cases of no abnormal detection were transient ischemic attack, and the other one was a perforating infarction. The earliest detection time in cortical infarction cases was 1 hour and 20 minutes. On the other hand, the earliest detection time in perforating infarction cases was 3 hours. Detective ability for acute cerebral infarction on diffusion-weighted imaging by low field MRI was depending on both size and lesion of infarction. That is to say, either small size or brain stem infarction was hard to detect. Thin slice and vertical slice examination for the infarction may improve to diagnose in low field MRI. Our conclusion is acute cerebral infarction was able to be diagnosed on diffusion-weighted imaging by low field as well as high field MRI. (author)

    Full Text Available Aim. To study the effect of left ventricular (LV systolic dysfunction on cerebral hemodynamic in patients with ST segment elevation myocardial infarction (STEMI during acute period. Material and methods. Cerebral hemodynamics ultrasound assessment was performed in the extra-and intracranial vessels in 118 patients with STEMI. Results. Significant changes in cerebral hemodynamics were found in LV systolic dysfunction with ejection fraction (LVEF ≤40% due to hemispheric blood flow asymmetry in the middle cerebral artery (MCA as large as 45.1±6.7% with correlation coefficient r=-0.87. Compensation of cerebral blood flow was manifested in vasoconstriction or vasodilation (resistive index 0.63-0.76 and 0.49-0.43 c.u., respectively. Conclusion. A strong relationship between LV systolic dysfunction and cerebral hemodynamic was found in patients with STEMI. It was manifested in significant contralateral hemispheric blood flow asymmetry in MCA in patients with LVEF ≤40%. Reduction in cerebral blood flow velocity activated autoregulation mechanism in the form of vasoconstriction or vasodilation.

    Knowledge of MRI findings in pediatric cerebral infarction is limited. To determine whether cortical necrosis and network injury appear in the acute phase in post-stroke children and to identify anatomical location of acute network injury and the ages at which these phenomena are seen. Images from 12 children (age range: 0-9 years; neonates [<1 month], n=5; infants [1 month-12 months], n=3; others [≥1 year], n=4) with acute middle cerebral artery (MCA) cortical infarction were retrospectively analyzed. Cortical necrosis was defined as hyperintense cortical lesions on T1-weighted imaging that lacked evidence of hemorrhage. Acute network injury was defined as hyperintense lesions on diffusion-weighted imaging that were not in the MCA territory and had fiber connections with the affected cerebral cortex. MRI was performed within the first week after disease onset. Cortical necrosis was only found in three neonates. Acute network injury was seen in the corticospinal tract (CST), thalamus and corpus callosum. Acute network injury along the CST was found in five neonates and one 7-month-old infant. Acute network injury was evident in the thalamus of four neonates and two infants (ages 4 and 7 months) and in the corpus callosum of five neonates and two infants (ages 4 and 7 months). The entire thalamus was involved in three children when infarction of MCA was complete. In acute MCA cortical infarction, MRI findings indicating cortical necrosis or acute network injury was frequently found in neonates and early infants. Response to injury in a developing brain may be faster than that in a mature one. (orig.)

    2004-01-01

    Objective To confirmed reliability and feasibility of intranasal nerve growth factor (NGF) bypassing the blood-brain barrier and its potential neuroprotective effects on acute cerebral ischemia.Methods (1) To assay NGF concentrations in different brain regions after middle cerebral artery occlusion (MCAO).Rats were randomly divided into intranasal (IN) NGF, intravenous (Ⅳ) NGF, and untreated group (n =4). The concentrations of NGF of different brain regions in the three groups after MCAO were measured by ELISA. (2) To observe neuroprotective action of NGF on focal cerebral ischemic damage. Rats were randomly assigned to 4 groups: IN vehicle, IN NGF,Ⅳ vehicle, Ⅳ NGF (n = 8). Treatment was initiated 30 minutes after onset of MCAO and given again 24 hours later. Three neurologic behavioral tests were performed 24 and 48 hours following onset of MCAO. Corrected infarct volumes were determined 48 hours after onset of MCAO.Results The olfactory bulb in IN NGF group obtained the highest concentration (3252 pg/g) of NGF among all regions, followed by the hippocumpus. The NGF concentrations in the olfactory bulb and hippocampus in IN NGF group were markedly higher than that in Ⅳ NGF and control groups. The infarct volume in IN NGF group was markedly reduced by 38.8% compared with IN vehicle group. IN NGF group vestibulum function markedly improved compared with IN vehicle group at 24 and 48 hours after onset of MCAO (P24h = 0.02 and P48h = 0.04, respectively).Conclusion Intranasal NGF could pass through the blood-brain barrier, reach the central nervous system, reduce infarct volume, and improve neurologic function in rats following MCAO. Intranasal delivery of NGF may be a promising treatment for stroke.

    The objective of this study was to investigate the association between serum resistin levels and acute cerebral infarction (ACI). PubMed, SpringerLink, Wiley, EBSCO, Ovid, Web of Science, Wanfang, China National Knowledge Infrastructure, and VIP databases (last updated search in October 2014) were exhaustively searched, and data from the eligible studies were extracted and analyzed to assess the association between serum resistin levels and ACI. STATA software (version 12.0, Stata Corporation, College Station, TX, USA) was utilized for data analysis. Ten studies including 1829 ACI patients and 1557 healthy controls were eligible for inclusion in the meta-analysis. Our major result revealed that ACI patients exhibited higher serum resistin levels compared with healthy controls. Asubgroup analysis based on ethnicity showed a significant association between serum resistin levels and ACI in Asians, but surprisingly not in Caucasians. The results of our meta-analysis suggest that serum resistin levels are associated with an increased risk of ACI.

    Cerebral vasospasm (CV) is one of the most dreaded complications in patients who survive acute subarachnoid haemorrhage (SAH), and conventional cerebral angiography (DSA) is the gold standard for its diagnosis. We evaluated CT angiography (CTA) as a non-invasive alternative for diagnosis of CV and assessed if CTA could have a role in choosing appropriate treatment. Consecutive patients with SAH and suspected vasospasm were included when DSA was performed within 24 h from CTA. Two neuro-radiologists retrospectively analysed CTA and DSA studies independently. Assessment included presence of central and peripheral vasospasm and grading of severity of central CV. A treatment recommendation based on CTA was compared to actual treatment received. Final analysis included 34 patients. CTA was more accurate for diagnosis of central then for peripheral CV with high sensitivity (reader 1, 91%; reader 2, 92%), specificity (reader 1, 73%; reader 2, 90%), accuracy, positive predictive value and negative predictive value for central vasospasm. For grading the severity of CV CTA's sensitivity, specificity and accuracy were high for most central arteries. The reader's recommendation of angioplasty according to CTA was significantly predictive of actual receipt of angioplasty but overestimated actual receipt of triple H treatment. CTA is adequate for detecting central vasospasm in symptomatic SAH patients. A negative result should not prevent further investigation especially when evaluating arterial segments adjacent to metal artefacts from coils or clips. CTA is helpful in treatment decision making specifically regarding the need for balloon angioplasty. (orig.)

    2013-01-01

    Full Text Available An 80-year-old woman with a history of congestive heart failure, atrial fibrillation, and hypertension was transferred to our institution with hematemesis. Her drug regimen included 2 mg warfarin potassium/day to prevent thromboembolic events. Transthoracic echocardiography (TTE performed at 78 years of age revealed a mass attached to the noncoronary cusp and a cardiac tumor was suspected. The patient declined surgery and was meticulously followed up with periodic TTE. Upper gastroendoscopy revealed a gastric ulcer with an exposed blood vessel; anticoagulant therapy was ceased. On day 15 of admission, acute cerebral infarction occurred. Heparin sodium and warfarin potassium were administered rapidly, and her symptoms improved. TTE revealed no alteration of the mobile, string-like mass attached to the noncoronary cusp. Cardiac tumor was considered the cause of cerebral infarction, and the patient consented to surgical therapy. Pathological examination of the resected tumor suggested papillary fibroelastoma (PFE. Although no guidelines exist for PFE management, a mobile, cardiac tumor necessitates surgical resection to prevent thromboembolic events, even when small in size.

    Acute mountain sickness (AMS) is a common condition among non-acclimatized individuals ascending to high altitude. However, the underlying mechanisms causing the symptoms of AMS are still unknown. It has been suggested that AMS is a mild form of high-altitude cerebral edema both sharing a common pathophysiological mechanism. We hypothesized that brain swelling and consequently AMS development is more pronounced when subjects exercise in hypoxia compared to resting conditions. Twenty males were studied before and after an eight hour passive (PHE) and active (plus exercise) hypoxic exposure (AHE) (F(i)O(2) = 11.0%, P(i)O(2)∼80 mmHg). Cerebral edema formation was investigated with a 1.5 Tesla magnetic resonance scanner and analyzed by voxel based morphometry (VBM), AMS was assessed using the Lake Louise Score. During PHE and AHE AMS was diagnosed in 50% and 70% of participants, respectively (p>0.05). While PHE slightly increased gray and white matter volume and the apparent diffusion coefficient, these changes were clearly more pronounced during AHE but were unrelated to AMS. In conclusion, our findings indicate that rest and especially exercise in normobaric hypoxia are associated with accumulation of water in the extracellular space, however independent of AMS development. Thus, it is suggested that AMS and HACE do not share a common pathophysiological mechanism.

    Full Text Available In stage V twin–twin transfusion syndrome (TTTS, up to 50% of surviving twins die or experience permanent disabilities, likely due to acute intertwin hemorrhage resulting in sudden severe anemia of the survivor. Although fetal middle cerebral artery (MCA Doppler studies demonstrate strong correlation with fetal hemoglobin values, acute hemorrhagic events are more difficult to diagnose, and optimal timing of delivery of the survivor poses an obstetric dilemma. We report a case of newly diagnosed stage V TTTS at 28 weeks gestation, complicated by acute severe anemia diagnosed by significantly abnormal fetal MCA Doppler studies. The anemic twin was urgently delivered and is doing well without significant sequelae.

    Background The dialysis disequilibrium syndrome is characterized by neurologic deterioration and cerebral edema which occurs after hemodialysis. The purpose of this study was to investigate the pathogenesis of acute cerebral and pulmonary edema induced by hemodialysis.Methods We evaluated the effects of hemodialysis on the biochemical and hemodynamic parameters of the plasma and cerebrospinal fluid, including the intracranial pressure, dry/wet ratio, and pulmonary edema index, and we also examined the pathological changes of the brain and lung tissue in dogs suffering from uremia.Results Seventy-two hours after bilateral ureteral ligation, 10 uremic dogs were hemodialyzed for 2 hours, yielding a 73.6% and 60.1% decrease in the plasma urea and creatinine, respectively, a decrease in the plasma osmolality from (359±18) mOsm/kgH2O to (304±6) mOsm/kgH2O (P <0.01 ), a decrease in the dry/wet ratio of the lung and brain tissue,and an increase in the hemodynamic parameters (right atrial pressure, right ventricular pressure, pulmonary artery pressure, pulmonary capillary wedge pressure, and central venous pressure), intracranial pressure, total pulmonary resistance index, and pulmonary edema index. Moreover, the pathological examination revealed lung and brain edema in the dialyzed dogs. This group was compared to 3 control groups: 6 uremic dogs which were sham dialyzed without dialysate so that no fall in the plasma urea occurred, and 12 uremic and 12 nonuremic animals that were not dialyzed.However, the parameters mentioned above were not significantly changed among these 3 control groups.Conclusions The acute brain and lung edema in our model appeared to be primarily due to a large osmotic gradient between the plasma and the brain and lung. This is the "urea reverse effect" which promoted the osmotically-induced lung and brain swelling.

    2016-01-01

    Patient: Female, 63 Final Diagnosis: Drug-induced hyponatremic encephalopathy Symptoms: Seizures • coma Medication: Hypertonic 3% saline infusion Clinical Procedure: — Specialty: Internal Medicine Objective: Unusual clinical course Background: Drug-induced hyponatremia characteristically presents with subtle psychomotor symptoms due to its slow onset, which permits compensatory volume adjustment to hypo-osmolality in the central nervous system. Due mainly to the syndrome of inappropriate antidiuretic hormone secretion (SIADH), this condition readily resolves following discontinuation of the responsible pharmacological agent. Here, we present an unusual case of life-threatening encephalopathy due to adverse drug-related effects, in which a rapid clinical response facilitated emergent treatment to avert life-threatening acute cerebral edema. Case Report: A 63-year-old woman with refractory depression was admitted for inpatient psychiatric care with a normal physical examination and laboratory values, including a serum sodium [Na+] of 144 mEq/L. She had a grand mal seizure and became unresponsive on the fourth day of treatment with the dual serotonin and norepinephrine reuptake inhibitor [SNRI] duloxetine while being continued on a thiazide-containing diuretic for a hypertensive disorder. Emergent infusion of intravenous hypertonic (3%) saline was initiated after determination of a serum sodium [Na+] of 103 mEq/L with a urine osmolality of 314 mOsm/kg H20 and urine [Na+] of 12 mEq/L. Correction of hyposmolality in accordance with current guidelines resulted in progressive improvement over several days, and she returned to her baseline mental status. Conclusions: Seizures with life-threatening hyponatremic encephalopathy in this case likely resulted from co-occurring SIADH and sodium depletion due to duloxetine and hydrochlorothiazide, respectively. A rapid clinical response expedited diagnosis and emergent treatment to reverse life-threatening acute cerebral edema

  8. Effect of acute and repeated restraint stress on glucose oxidation to CO2 in hippocampal and cerebral cortex slices

    Torres I.L.S.

    2001-01-01

    Full Text Available It has been suggested that glucocorticoids released during stress might impair neuronal function by decreasing glucose uptake by hippocampal neurons. Previous work has demonstrated that glucose uptake is reduced in hippocampal and cerebral cortex slices 24 h after exposure to acute stress, while no effect was observed after repeated stress. Here, we report the effect of acute and repeated restraint stress on glucose oxidation to CO2 in hippocampal and cerebral cortex slices and on plasma glucose and corticosterone levels. Male adult Wistar rats were exposed to restraint 1 h/day for 50 days in the chronic model. In the acute model there was a single exposure. Immediately or 24 h after stress, the animals were sacrificed and the hippocampus and cerebral cortex were dissected, sliced, and incubated with Krebs buffer, pH 7.4, containing 5 mM glucose and 0.2 µCi D-[U-14C] glucose. CO2 production from glucose was estimated. Trunk blood was also collected, and both corticosterone and glucose were measured. The results showed that corticosterone levels after exposure to acute restraint were increased, but the increase was smaller when the animals were submitted to repeated stress. Blood glucose levels increased after both acute and repeated stress. However, glucose utilization, measured as CO2 production in hippocampal and cerebral cortex slices, was the same in stressed and control groups under conditions of both acute and chronic stress. We conclude that, although stress may induce a decrease in glucose uptake, this effect is not sufficient to affect the energy metabolism of these cells.

    2006-01-01

    BACKGROUND: Aspirin can decrease the incidence risk of high-risk crowdgroup of cerebral infarction, but there are still controversy if it might decrease the degree of disease in degree of patients with acute cerebral infarction.OBJECTIVE: To observe the effect of lower dose of aspirin during taking for a long time on disease degree of disease following onset of acute cerebral infarction.DESIGN: Grouping according to the admission time and 1:1 paired observation.SETTING: Department of Neurology, Qilu Hospital of Shandong University.PARTICIPANTS: The participants in present study were 321 patients with acute cerebral infarction who received treatments in the Department of Neurology, Qilu Hospital of Shandong University from January 1999 to June 2000. There were 190 male and 131 female ,with mean (65±11 )years of age. Inclusive criteria: ① A focal neurological disturbance occurred suddenly and had lasted for more than 24 hours, patients were admitted within 3 days after onset of disease; ② A computed tomography of the brain was performed and excluded hemorrhage in all patients; ③ The patients were proved internal carotid occlusions by clinical features and image findings; ④ The functions of limbs were normal (before the first stroke) or almost normal (before the second stroke). Exclusive criteria: ①The patients who had have cardiogenic cerebral embolism; ②The patients who had taken warfarin orally and other platelet agglutination drugs.METHODS: ①All the patients were divided into 2 groups according to whether they had taken aspirin before: aspirin-treated group (n=110) and blank control group (n=211). There were 70 male and 40 female in aspirin-treated group, with average(65±10) years of age.All patients had taken 50-100 mg/d aspirin for 6 months to 10 years before onset. There were 120 male and 91 female in blank control group, with average (65±13)years of age. Patients received a clinical scoring within 3 days and similar therapeutic measures (such

    2004-10-01

    Hyperhomocysteinemia is an independent risk factor for atherothrombotic cerebral stroke. Vitamin B12 and folic acid are important determinants of homocysteine metabolism. We aimed to evaluate the relationship, if present, between vitamin B12 and folic acid levels and acute cerebral stroke in this study. Blood aliquots drawn within 24 hours after the stroke from hospitalized patients (n=66) with the diagnosis of acute ischemic cerebrovascular episode and also blood samples from 38 healthy controls without any vascular risk factor were analyzed. With a competitive, chemoluminescence assay, serum levels of vitamin B12 and folic acid were measured in blood samples taken within 24 hours after the stroke. The differences and correlations were tested using frequency test, student-t test and multivariate analysis. Mean serum vitamin B12 levels were significantly lower in the patients than in the control subjects, 245.40 (S.D.: 72.9) and 343.2 (S.D.: 113.0) pg/ml respectively (p=0.0001). This difference was independent from other risk factors. Likewise, mean serum folic acid levels were lower in the patients than in the control subjects, 4.62 (S.D.: 1.94) and 5.97 (S.D.: 1.19) ng/ml, respectively (p=0.003). Mean serum levels of vitamin B12 and folate at the convalescence phase were 253.05 (S.D.: 68.78) pg/ml and 4.48 (S.D.: 2.08) ng/ml, respectively; the values obtained at the acute phase were not significantly different from the values obtained at the convalescence phase. We conclude that low vitamin B12 and folic acid concentrations are associated with an increased risk of stroke, and the relationship for vitamin B12 is independent from the other known modifiable stroke risk factors. For understanding the effects of B12 and folate in stroke patients, more detailed follow-up studies with long period are needed.

    2010-05-01

    We developed fully automated software for dynamic susceptibility contrast (DSC) MR perfusion-weighted imaging (PWI) to efficiently and reliably derive critical hemodynamic information for acute stroke treatment decisions. Brain MR PWI was performed in 80 consecutive patients with acute nonlacunar ischemic stroke within 24h after onset of symptom from January 2008 to August 2009. These studies were automatically processed to generate hemodynamic parameters that included cerebral blood flow and cerebral blood volume, and the mean transit time (MTT). To develop reliable software for PWI analysis, we used computationally robust algorithms including the piecewise continuous regression method to determine bolus arrival time (BAT), log-linear curve fitting, arrival time independent deconvolution method and sophisticated motion correction methods. An optimal arterial input function (AIF) search algorithm using a new artery-likelihood metric was also developed. Anatomical locations of the automatically determined AIF were reviewed and validated. The automatically computed BAT values were statistically compared with estimated BAT by a single observer. In addition, gamma-variate curve-fitting errors of AIF and inter-subject variability of AIFs were analyzed. Lastly, two observes independently assessed the quality and area of hypoperfusion mismatched with restricted diffusion area from motion corrected MTT maps and compared that with time-to-peak (TTP) maps using the standard approach. The AIF was identified within an arterial branch and enhanced areas of perfusion deficit were visualized in all evaluated cases. Total processing time was 10.9+/-2.5s (mean+/-s.d.) without motion correction and 267+/-80s (mean+/-s.d.) with motion correction on a standard personal computer. The MTT map produced with our software adequately estimated brain areas with perfusion deficit and was significantly less affected by random noise of the PWI when compared with the TTP map.

    2005-01-01

    Full Text Available Abstract Background Asthma and sickle cell disease are common conditions that both may result in pulmonary complications. We hypothesized that children with sickle cell disease with concomitant asthma have an increased incidence of vaso-occlusive crises that are complicated by episodes of acute chest syndrome. Methods A 5-year retrospective chart analysis was performed investigating 48 children ages 3–18 years with asthma and sickle cell disease and 48 children with sickle cell disease alone. Children were matched for age, gender, and type of sickle cell defect. Hospital admissions were recorded for acute chest syndrome, cerebral vascular accident, vaso-occlusive pain crises, and blood transfusions (total, exchange and chronic. Mann-Whitney test and Chi square analysis were used to assess differences between the groups. Results Children with sickle cell disease and asthma had significantly more episodes of acute chest syndrome (p = 0.03 and cerebral vascular accidents (p = 0.05 compared to children with sickle cell disease without asthma. As expected, these children received more total blood transfusions (p = 0.01 and chronic transfusions (p = 0.04. Admissions for vasoocclusive pain crises and exchange transfusions were not statistically different between cases and controls. SS disease is more severe than SC disease. Conclusions Children with concomitant asthma and sickle cell disease have increased episodes of acute chest syndrome, cerebral vascular accidents and the need for blood transfusions. Whether aggressive asthma therapy can reduce these complications in this subset of children is unknown and requires further studies.

    Iversen, Peter; Bak, Lasse Kristoffer; Waagepetersen, Helle Sønderby

    2009-01-01

    BACKGROUND & AIMS: It is unclear whether patients with hepatic encephalopathy (HE) have disturbed brain oxygen metabolism and blood flow. METHODS: We measured cerebral oxygen metabolism rate (CMRO(2)) by using (15)O-oxygen positron emission tomography (PET), and cerebral blood flow (CBF) by using....../min in patients with HE, 0.47 +/- 0.02 in patients without HE, and 0.49 +/- 0.03 in healthy subjects. CMRO(2) and CBF were correlated, and both variables correlated negatively with arterial ammonia concentration. Analysis of regional values, using individual magnetic resonance co-registrations, showed...... that the reductions in CMRO(2) and CBF in patients with HE were essentially generalized throughout the brain. CONCLUSIONS: The observations imply that reduced cerebral oxygen consumption and blood flow in cirrhotic patients with an acute episode of overt HE are associated with HE and not cirrhosis as such...

    2015-08-01

    Clinicians observed that the treatment of premature human newborns for anemia with erythropoietin (Epo) also improved their respiratory autonomy. This observation is in line with our previous in vitro studies showing that acute and chronic Epo stimulation enhances fictive breathing of brainstem-spinal cord preparations of postnatal day 3-4 mice during hypoxia. Furthermore, we recently reported that the antagonization of the cerebral Epo (by using the soluble Epo receptor; sEpoR) significantly reduced the basal ventilation and the hypoxic ventilatory response of 10 days old mice. In this study, we used transgenic (Tg21) mice to investigate the effect of the chronic cerebral Epo overexpression on the modulation of the normoxic and hypoxic ventilatory drive during the post-natal development. Ventilation was evaluated by whole body plethysmography at postnatal ages 3 (P3), 7 (P7), 15 (P15) and 21 (P21). In addition Epo quantification was performed by RIA and mRNA EpoR was evaluated by qRT-PCR. Our results showed that compared to control animals the chronic Epo overexpression stimulates the hypoxic (but not the normoxic) ventilation assessed as VE/VO2 at the ages of P3 and P21. More interestingly, we observed that at P7 and P15 the chronic Epo stimulation of ventilation was attenuated by the down regulation of the Epo receptor in brainstem areas. We conclude that Epo, by stimulating ventilation in brainstem areas crucially helps tolerating physiological (e.g., high altitude) and/or pathological (e.g., respiratory disorders, prematurity, etc.) oxygen deprivation at postnatal ages.

    Full Text Available Background/Purpose: There is evidence supporting an association between ischemic stroke and periodontitis in western countries. Differing genetic backgrounds and lifestyles among populations may affect this association. The aim of our study was to determine whether antibody titers to Porphyromonas gingivalis are associated with acute cerebral infarction in the Chinese population. Materials and Methods: This case-control study was conducted on 88 acute cerebral infarction patients and 40 healthy control subjects. Serum immunoglobulin-G (IgG antibody to P. gingivalis was analyzed by enzyme-linked immune sorbent assay. Serum lipids were determined with the automatic biochemical analyzer. Fibrinogen was measured using automated coagulation analyzer. High-sensitivity C-reactive protein (hs-CRP and interleukin-6 (IL-6 were quantified using commercial ELISA kits. The intima-media thickness of the common carotid arteries (IMT-CCA was measured by ultrasonography. Results: The results showed that P. gingivalis IgG antibody levels were significantly higher in acute cerebral infarction cases than in healthy controls (mean ± standard deviation, 11.06 ± 1.49 vs. 9.15 ± 1.70, P < 0.001. There were significant correlations of P. gingivalis IgG titer with total cholesterol (r = 0.34, P = 0.001, low-density lipoprotein (r = 0.39, P < 0.001, apolipoprotein-B (r = 0.30, P = 0.004, hs-CRP (r = 0.35, P = 0.001, IL-6 (r = 0.27, P = 0.011, and IMT-CCA (left: r = 0.306, P = 0.004; right: r = 0.241, P = 0.024. Conclusion: Antibody titers to P. gingivalis are associated with acute cerebral infarction in the Chinese population.

  5. Changes of cerebral blood flow in rats with acute cerebral ischemia and the effect of nitric oxide donor S-nitroso-N-acetyl-penicillamine

    Feng Gao; Zhiqiang Yi; Guijun Lin

    2006-01-01

    BACKGROUND: Previous studies show that nitric oxide donor can increase cerebral blood flow and improve the function of neurons in cerebral ischemia, but the change does not happen in all the models of cerebral ischemia. OBJECTIVE: To observe the effects of nitric oxide donor S-nitroso-N-acetyl-penicillamine (SNAP) on the cerebral blood flow, cyclic guanosine monophosphate (cGMP) content in cerebral cortex, infarct volume and blood pressure in acute ischemic rat brain.DESIGN: A randomized and control animal experiment. SETTING: Department of Neurosurgery, Aerospace Central Hospital, Peking University. MATERIALS: Twenty-eight male Wistar rats of SPF grade, weighing 250-300 g, aged 10-12 weeks were randomly divided into control group (n =14) and SNAP-treated group (n =14). SNAP (5 mg/bottle) was provided by Beijing Chemical Reagent Company. Laser Doppler Flowmeter (FLO C1; Omegawave Inc., Tokyo, Japan) and immunoassay kit (Amersham Pharmacia Biotech, UK) were applied.METHODS: ① Model establishment: In the control group, models of cerebral ischemia were induced by ligating right common, internal and external carotid arteries; In the SNAP-treated group, models of cerebral ischemia were induced by ligating right common and external carotid arteries, followed by occluding middle cerebral artery and ligating internal carotid artery. ② Administration: In the SNAP-treated group, SNAP (100 μg/kg) was intravenously infused within 2 minutes, whereas in the control group, phosphate buffered saline (PBS, 1 mL) was intravenously infused (0.5 mL per minute). Six rats were used to measure the volume of cerebral infarction, and the other 8 rats were used to determine other indexes in each group respectively. ③ Determination of indexes: Regional cerebral blood flow (rCBF) was continuously measured by laser-Doppler flowmetry in the ischemic penumbra and contralateral cortex under the continuous monitoring of blood pressure, cGMP concentrations in brain tissue were determined

    Full Text Available We observed mitochondrial connexin43 (mtCx43 expression under cerebral ischemia-reperfusion (I/R injury, analyzed its regulation, and explored its protective mechanisms. Wistar rats were divided into groups based on injections received before middle cerebral artery occlusion (MCAO. Cerebral infarction volume was detected by 2,3,5-triphenyltetrazolim chloride staining, and cell apoptosis was observed by transferase dUTP nick end labeling. We used transmission electron microscopy to observe mitochondrial morphology and determined superoxide dismutase (SOD activity and malondialdehyde (MDA content. MtCx43, p-mtCx43, protein kinase C (PKC, and p-PKC expression were detected by Western blot. Compared with those in the IR group, cerebral infarction volumes in the carbenoxolone (CBX and diazoxide (DZX groups were obviously smaller, and the apoptosis indices were down-regulated. Mitochondrial morphology was damaged after I/R, especially in the IR and 5-hydroxydecanoic acid (5-HD groups. Similarly, decreased SOD activity and increased MDA were observed after MCAO; CBX, DZX, and phorbol-12-myristate-13-acetate (PMA reduced mitochondrial functional injury. Expression of mtCx43 and p-mtCx43 and the p-Cx43/Cx43 ratio were significantly lower in the IR group than in the sham group. These abnormalities were ameliorated by CBX, DZX, and PMA. MtCx43 may protect the neurovascular unit from acute cerebral IR injury via PKC activation induced by mitoKATP channel agonists.

    Acute intracerebral hemorrhage (ICH) associated with mild anemia is commonly observed on radiological examination, and there are several reports of ruptured aneurysms occurring with ICH but without accompanying subarachnoid hemorrhage. However, the relationship among computed tomography (CT), magnetic resonance imaging (MRI), and intraoperative findings of ICH caused by ruptured cerebral aneurysm in patients with severe chronic anemia has been rarely reported and is poorly understood. Here, we report atypical radiological and intraoperative findings of acute ICH caused by ruptured cerebral aneurysm in a patient with severe chronic anemia. A 64-year-old man with anemia was admitted to our hospital after he experienced left hemiparesis and a disturbance of consciousness. At a referring institution, he showed evidence of macrocytic anemia (white blood cell count, 9,000/μL; red blood cell count, 104×10(4)/μL; hemoglobin, 4.0 g/dL; hematocrit, 12.2%; and platelet count, 26.6×10(4)/μL). Both CT and MRI showed a right frontal ICH. The outer ring of the hematoma appeared as low-density area on CT, a low-intensity area on T1-weighted MRI, and a high-intensity area on T2-weighted MRI with a serous component. The patient received a blood transfusion and underwent surgical removal of the hematoma the following day. The white serous effusion visualized with CT and MRI was identified as a blood clot in the hematoma cavity. The blood that leaks from blood vessels appears as a high-intensity area on CT because it undergoes plasma absorption in a solidification shrinkage process, and is, therefore, concentrated. Although we did not examine the white effusion to determine if serous components were present, we speculated that the effusion may have contained serous components. Therefore, we removed the part of the effusion that appeared as a low-density area on CT. The presence of ICH without subarachnoid hemorrhage suggested the possible adhesion and rupture of a previous

    Context • Acute, focal, cerebral ischemic stroke is a leading cause of morbidity and mortality worldwide. Acupuncture is an emerging alternative therapy for treatment of acute brain ischemia. Nevertheless, the precise mechanism underlying the neuroprotective effects of acupuncture has not been elucidated. Nuclear factor κB (NF-κB) and nuclear factor of κ light polypeptide gene enhancer in B cell inhibitor alpha (IκB-α) are involved in cerebral inflammation. However, the involvement of NF-κB and IκB-α in the protective effects of acupuncture on ischemic tolerance remains unknown. Objective • The study evaluated the hypothesis that acupuncture can exert a neuroprotective action in a rat model of middle cerebral artery occlusion (MCAO). Design • The rats were randomly divided into a normal group (N), a sham model group (SM), an MCAO model group (M), a sham acupuncture group (SA), and an acupuncture group (A). Setting • All of processes of this study were conducted at Hubei University of Chinese Medicine (Hubei Shang, China). Animals • The animals were 100 Sprague-Dawley rats, aged 3 mo. Intervention • Craniotomy and electrocoagulation of the middle cerebral artery were conducted to generate acute, focal, cerebral ischemic models in 3 groups, excluding the N and SM groups. The SM group received a surgical fenestration similar to the M group, but the procedure did not include the coagulation of the exposed artery. In the A group, acupuncture was administered at the acupoints Baihui (GV-20) and Renzhong (GV-26). In the SA group, sham acupuncture was performed at a depth of 5 mm at a position close to the left side of the GV-20 and GV-26 points. The N, M, and SM groups received neither the acupuncture nor the sham acupuncture treatment. Outcome Measures • The study (1) evaluated neurological function using the modified neurological severity score; (2) examined the ultrastructure; (3) assessed the infarct volume; (4) determined levels of serum

    Objective: To investigate the roles of chloramphenicol (CAP) preconditioning in the oxidative respiratory function of cerebral mitochondria in rats exposed to acute hypoxia during acute hypoxia by observing the changes of mitochondrial oxidative respiratory function and cytochrome C oxidase (COX) activity. Methods: Adult male Wistar rats were randomly divided into 4 groups: control (C), medication (M), hypoxia (H), and medication plus hypoxia (MH). Rats in groups M and MH were administered by peritoneal injection of CAP (50 mg/kg) every 12 h for 7 d before decapitation, but those in groups H and MH were exposed to a hypobaric chamber simulating 5 000 m high altitude for 24 h. The rat cerebral cortex was removed and mitochondria were isolated by centrifugation. Mitochondrial respiratory function and COX activity were measured by Clark oxygen electrode. Results: Compared with Group C, Group H showed significantly elevated state 4respiration (ST4), decreased state 3 respiration (ST3), and respiratory control rate (RCR) in mitochondrial respiration during acute hypoxic exposure. ST3 in Group MH was significantly lower than that in Group C, but was not significantly different from that in Groups H and M, while ST4 in Group MH was significantly lower than that in groups C and H. RCR in Group MH was higher than that in Group H, but lower than that in Group C. COX activity in Group H was significantly lower than that in Group C. In Group MH, COX activity increased and was higher than that in Group H, but was still lower than that in Group C. Conclusion: Acute hypoxic exposure could lead to mitochondrial respiratory dysfunction, suggesting that CAP preconditioning might be beneficial to the recovery of rat respiratory finction. The change of COX activity is consistent with that of mitochondrial respiratory function during acute hypoxic exposure and CAP-administration, indicating that COX plays an important role in oxidative phosphorylation function of mitochondria from

    BACKGROUND: Serum high sensitive C-reactive protein (hs-CRP), which regards as a high sensitive mark of systemic inflammatory response syndrome, can provide a lot of valuable information for the treatment and prognosis of cerebrovascular disease.OBJECTIVE: To observe the differences of blood glucose, lipid, homocysteine and previous disease history among patients with acute cerebral infarction at various levels of hs-CRP and compare changes of hs-CRP of patients with various degrees ofneurologic impairment.DESIGN: Contrast observation.SETTING: Department of Neurology, Shenzhou Hospital, Shenyang Medical College.PARTICIPANTS: A total of 102 patients with acute cerebral infarction were selected from Department of Neurology, Shenzhou Hospital of Shenyang Medical College from February 2005 to September 2006,including 55 males and 47 females aged from 55 to 86 years. All accepted patients met the diagnostic criteria of cerebral infarction established by the Fourth National Cerebrovascular Disease Academic Meeting and were diagnosed with CT or MRI examination. All patients provided the confirmed consent. Based on clinical criteria of neurologic impairment established by the Fourth National Cerebrovascular Disease Academic Meeting, patients were randomly divided into mild group (0- 15 points, n =46), moderate group (16- 30points, n =38) and severe group (31 - 45 points, n =18). In addition, based on hs-CRP level within 72 hours,patients were divided into normal group (hs-CRP ≤ 3 mg/L, n =53) and increasing group (hs-CRP > 3 mg/L,n =49).METHODS: ① 2 mL venous blood was selected from hospitalized patients in the next morning to separate serum. Quantitative measurement of hs-CRP was dealt with Latex Enhnced Turbidimetric Immunoassay (LETIA). ② Fasting venous blood was colleted from hospitalized patients in the next morning to measure numeration of white blood cells, fibrinogen, blood glucose, total cholesterol (TC), triacylglycerol (TG), high density lipoprotein

    The present work was aimed at studying the state of the inferior vena cava system according to the findings of duplex scanning in dynamics of acute cerebral circulation impairments (ACCI). Amongst 100 patients with ACCI, lower limb vein deep thrombosis (LLVDT) was revealed in 57% of cases. The incidence of LLVDT in patients with intracerebral haemorrhage was higher than in those with ischaemic stroke, however there were no statistically significant differences between the type of ACCI (p=0.06) and subtypes of ischaemic stroke (atherothrombotic, ceardioembolic) (p = 0.68). The main risk factors for LLVDT are the presence of pronounced motion deficit in the extremities, induced by the underlying disease (p=0.02) and immobilization. In the overwhelming majority of patients (81%) thrombosis localized isolatedly in the crural veins. Ascending thrombosis and the development of a floating thrombus were represented mainly on the side of motility deficit in the extremities. We have confirmed a strong association between positive dynamics in the neurological status of patients and frequency of recanalization of thrombi (p=0.043). Ultrasonographic examination of lower limb veins in dynamics of ACCI is an important component of preventive and therapeutic process.

    This study aims to investigate the clinical significance of post-interventional cerebral hyperdensities (PCHD) after endovascular mechanical thrombectomy in acute ischaemic stroke. Data of 102 consecutive patients who received post-interventional CT scans within 4.5 h after mechanical thrombectomy were analysed retrospectively. Sixty-two of 102 patients (60.8 %) had PCHD on their post-interventional CT scans. The most common site of PCHD was the basal ganglia. PCHD were persisting in 13 of 62 patients (21.0 %), and transient in the remaining 49 patients (79.0 %) within 24 h. Four patients with PCHD and four patients without PCHD suffered from parenchymal haemorrhage. Neither ASA nor Clopidogrel, Tirofiban or rtPA were risk factors for PCHD. Final infarction size was congruent with or bigger than areas of PCHD in 93.3 % of cases in our series. PCHD was not a risk factor for parenchymal haemorrhage in our series. The occurrence of PCHD was strongly related to the prior presence of infarction. PCHD was also a strong predictor for final infarction size. (orig.)

    2012-03-01

    Administration of erythropoietin (EPO) has been linked to cerebrovascular events. EPO reduces vascular conductance, possibly because of the increase in hematocrit. Whether EPO in itself affects the vasculature remains unknown; here it was evaluated in healthy males by determining systemic and cerebrovascular variables following acute (30,000 IU/d for 3 d; n=8) and chronic (5000 IU/week for 13 wk; n=8) administration of EPO, while the responsiveness of the vasculature was challenged during cycling exercise, with and without hypoxia. Prolonged administration of EPO increased hematocrit from 42.5 ± 3.7 to 47.6 ± 4.1% (PEPO administration. Yet, the two EPO regimes increased arterial pressure similarly (by 8±4 and 7±3 mmHg, respectively; P=0.01) through reduced vascular conductance (by 7±3 and 5±2%; PEPO regimes widened the arterial-to-jugular O(2) differences at rest as well as during normoxic and hypoxic exercise (PEPO to healthy humans lowers systemic and cerebral conductance independent of its effect on hematocrit.

    BACKGROUND:Several studies have confirmed that endothelin and endorphin are involved in the occurrence of cerebral vasospasm. However, the correlation of these factors to acute cerebral infarction-related risk factors needs to be confirmed.OBJECTIVE:To detect endothelin-1(ET-1)and beta-endorphin(β-EP)levels in plasma of patients with acute cerebral infarction,and to analyze the correlations of these factors to smoking,alcohol abuse, hypertension,diabetes mellitus,diseased region,diseased degree,gender,and other factors related to acute cerebral infarction. DESIGN:A case-control observation. SETTING:First Department of Neurology,Guangdong Hospital of Traditional Chinese Medicine; Department of Neurology,Second Affiliated Hospital of Sun Yat-sen University.PARTICIPANTS:Sixty-nine inpatients with acute cerebral infarction were admitted to the Department of Neurology,Second Affiliated Hospital of Sun Yat-sen University(March 2003-January 2004)and First Department of Neurology,Guangdong Hospital of Traditional Chinese Medicine(March - July 2004)and recruited for this study.All 69 inpatients corresponded to the diagnosis criteria of acute cerebral infarction,formulated in the National Working Conference of Cerebrovascular Disease in 1998,and were confirmed as acute cerebral infarction by CT/MRI.The patient group consisted of 35 males [(64±12)years old] and 34 females[(67±13 )years old].Among them,9 patients were smokers,7 were alcohol users,48 had a history of hypertension,and 16 had a history of diabetes mellitus.CT/MRI examinations revealed that 35 patients presented with left focus sites,11 with right ones and 23 with bilateral ones.Following attack,24 patients had Barthel Index Scale grading<40 points,21 patients 40-60 points,and 24 patients>60 points.An additional 59 healthy individuals,who received health examinations simultaneously,were included as controls.Among the control subjects,there were 37 males [(62±10)years old] and 22 females [(65±11) years old

    Major ozonated autohemotherapy is classically used in treating ischemic disorder of the lower limbs. In the present study, we performed major ozonated autohemotherapy treatment in patients with acute cerebral infarction, and assessed outcomes according to the U.S. National Institutes of Health Stroke Score, Modified Rankin Scale, and transcranial magnetic stimulation motor-evoked potential. Compared with the control group, the clinical total effective rate and the cortical potential rise rate of the upper limbs were significantly higher, the central motor conduction time of upper limb was significantly shorter, and the upper limb motor-evoked potential amplitude was significantly increased, in the ozone group. In the ozone group, the National Institutes of Health Stroke Score was positively correlated with the central motor conduction time and the motor-evoked potential amplitude of the upper limb. Central motor conduction time and motor-evoked potential amplitude of the upper limb may be effective indicators of motor-evoked potentials to assess upper limb motor function in cerebral infarct patients. Furthermore, major ozonated autohemotherapy may promote motor function recovery of the upper limb in patients with acute cerebral infarction.

    Objective: To investigate the early effect of thyrotropin-releasing hormone (TRH) on cerebral free radical reactions after acute brain injury in rabbits.Methods: 30 healthy white rabbits were randomly divided into three groups: Group A (n=10), Group B (n=12) and Group C (n=8). The rabbits in Group A and Group B were injured by direct hit. At 0.5-4 hours after injury, the rabbits in Group A were injected with TRH (8 mg/kg body weight) through a vein and the rabbits in Group B were injected with normal saline of equal volume. The rabbits in Group C served as the normal control. Then all the rabbits were killed and brain tissues were obtained. The content of lipoperoxide (LPO), the activity of superoxide dismutase (SOD) and the water content of the brain tissues were measured.Results: The contents of LPO and water in brain tissues in Group A were lower and the activity of SOD was higher than those of Group B (P<0.05). After injury, intracranial pressure (ICP) rose rapidly and continuously with time passing by. When TRH was given to the animals in Group A, the rising speed of ICP slowed down significantly.Conclusions: TRH can decrease the cerebral free radical reactions and cerebral edema after acute brain injury in rats.

    Full Text Available Objectives. This study was conducted to verify the necessity of corresponding prescription to the diagnosed pattern in acute cerebral infarction patients. Methods. We studied cerebral infarction patients hospitalized within 30 days after the ictus. Forty-four clinical indicators, Motricity Index (MI score, Scandinavian Stroke Scale (SSS score, and herbal prescriptions were checked twice, two weeks apart. The probability of each pattern was calculated based on the clinical indicators. Changes in MI score, SSS score, and the probability of fire-heat pattern were compared between the pattern-prescription correspondence group and the noncorrespondence group. Results. Increments of MI score and SSS score in the correspondence group were significantly greater than those of the noncorrespondence group (p=0.003, p=0.001 while the baseline score of the two groups showed no significant difference. Probability of fire-heat pattern decreased significantly in the correspondence group (p=0.013 while the noncorrespondence group showed no significant difference after the treatment. Conclusion. Acute cerebral infarction patients who are diagnosed as fire-heat pattern showed better improvement in dysfunctions caused by the disease when they took the pattern corresponding prescriptions. This study provides evidence for the necessity and usefulness of pattern identification in Traditional Korean Medicine.

    Li-Bao Hu; Nan Hong; Wen-Zhen Zhu

    2015-01-01

    Background:Intravoxel incoherent motion (IVIM) has the potential to provide both diffusion and perfusion information without an exogenous contrast agent,its application for the brain is promising,however,feasibility studies on this are relatively scarce.The aim of this study is to assess the feasibility of IVIM perfusion in patients with acute ischemic stroke (AIS).Methods:Patients with suspected AIS were examined by magnetic resonance imaging within 24 h of symptom onset.Fifteen patients (mean age was 68.7 ± 8.0 years) who underwent arterial spin labeling (ASL) and diffusion-weighted imaging (DWI) were identified as having AIS with ischemic penumbra were enrolled,where ischemic penumbra referred to the mismatch areas of ASL and DWI.Eleven different b-values were applied in the biexponential model.Regions of interest were selected in ischemic penumbras and contralateral normal brain regions.Fast apparent diffusion coefficients (ADCs) and ASL cerebral blood flow (CBF) were measured.The paired t-test was applied to compare ASL CBF,fast ADC,and slow ADC measurements between ischemic penumbras and contralateral normal brain regions.Linear regression and Pearson's correlation were used to evaluate the correlations among quantitative results.Results:The fast ADCs and ASL CBFs of ischemic penumbras were significantly lower than those of the contralateral normal brain regions (1.93 ± 0.78 μm2/ms vs.3.97 ± 2.49 μm2/ms,P =0.007;13.5 ± 4.5 ml· 100 g-1 ·min-1 vs.29.1 ± 12.7 ml·100 g-1 ·min-1,P < 0.001,respectively).No significant difference was observed in slow ADCs between ischemic penumbras and contralateral normal brain regions (0.203 ± 0.090 μm2/ms vs.0.198 ± 0.100 μm2/ms,P =0.451).Compared with contralateral normal brain regions,both CBFs and fast ADCs decreased in ischemic penumbras while slow ADCs remained the same.A significant correlation was detected between fast ADCs and ASL CBFs (r =0.416,P < 0.05).No statistically significant correlation was

    2013-09-01

    Full Text Available Introduction.Nicotinic acetylcholine receptors are present in the cerebral white matter (WM. We hypothesized that WM response to nicotine can be detected by diffusion tensor imaging (DTI; and that such responses may be associated with nicotine-led cognitive enhancement in sustained attention. MethodsA randomized, nicotine-placebo patch, crossover, double-blind clinical trial in two non-overlapping cohorts of smokers was used to test the hypothesis. The discovery cohort consisted of 39 subjects (N=20/19 controls/schizophrenic patients, age=36.8±10.1years and the replication cohorts consisted of 38 healthy smokers (31.7±10.5years. WM integrity was measured by fractional anisotropy (FA values for the whole brain and nine preselected WM tracts using tract-based-spatial-statistics. Results.Nicotine significantly enhanced FA values for the genu of corpus callosum compared with placebo (FAgenu (p=0.01 in smokers with low recent smoking exposure as measured by low average cotinine level. This finding was replicated in the second cohort (p=0.02. FAgenu values explained 22% of variance in performance of a sustained attention task during the nicotine session (p=0.006. However, this effect was limited to schizophrenia patients (r= 0.62 and 0.09; p=0.003 and 0.7 for patients and controls, respectively.Conclusion. Acute pharmacological influence of nicotine patch on WM integrity appeared present, but was dependent on nicotine intake from recent smoking. Change in the WM integrity in the genu of corpus callosum was assocatied with a significant proportion of variability of nicotine-led changes in sustained attention/working memory of the smokers. Further studies will be necessary to understand biophysical underpinning of the nicotine-related changes in FA.

    2006-01-01

    Full Text Available Diffusion- and perfusion-weighted magnetic resonance imaging (DWI and PWI was applied for stroke diagnose in 120 acute (<48 h ischemic stroke patients. At hyperacute (<6 h stage, it is difficult to find out the infarction zone in conventional T1 or T2 image, but it is easy in DWI, apparent diffusion coefficient (ADC map; when at 3–6-hour stage it is also easy in PWI, cerebral blood flow (CBF map, cerebral blood volume (CBV map, and mean transit time (MTT map; at acute (6–48 h stage, DWI or PWI is more sensitive than conventional T1 or T2 image too. Combining DWI with ADC, acute and chronic infarction can be distinguished. Besides, penumbra which should be developed in meaning was used as an indication or to evaluate the therapeutic efficacy. There were two cases (<1.5 h that broke the model of penumbra because abnormity was found in DWI but not that in PWI, finally they recovered without any sequela.

    The use of gold nanoparticles is increasing in medicine; however, their toxic effects remain to be elucidated. Studies show that gold nanoparticles can cross the blood-brain barrier, as well as accumulate in the brain. Therefore, this study was undertaken to better understand the effects of gold nanoparticles on rat brains. DNA damage parameters were evaluated in the cerebral cortex of adult rats submitted to acute and chronic administration of gold nanoparticles of two different diameters: 10 and 30nm. During acute administration, adult rats received a single intraperitoneal injection of either gold nanoparticles or saline solution. During chronic administration, adult rats received a daily single injection for 28 days of the same gold nanoparticles or saline solution. Twenty-four hours after either single (acute) or last injection (chronic), the rats were euthanized by decapitation, their brains removed, and the cerebral cortices isolated for evaluation of DNA damage parameters. Our study showed that acute administration of gold nanoparticles in adult rats presented higher levels of damage frequency and damage index in their DNA compared to the control group. It was also observed that gold nanoparticles of 30nm presented higher levels of damage frequency and damage index in the DNA compared to the 10nm ones. When comparing the effects of chronic administration of gold nanoparticles of 10 and 30nm, we observed that occurred significant different index and frequency damage, comparing with control group. However, there is no difference between the 10 and 30nm groups in the levels of DNA damage for both parameters of the Comet assay. Results suggest that gold nanoparticles for both sizes cause DNA damage for chronic as well as acute treatments, although a higher damage was observed for the chronic one.

  6. Forty-six Cases of Acute Cerebral Infarction Treated with the Combined Use of Acupuncture and Drugs

    2007-01-01

    Objective: To observe the clinical therapeutic effects of treatment for acute cerebral infarction with the combined use of acupuncture and drugs, and study the therapeutic mechanism. Methods: 88 cases of acute cerebral infarction were divided randomly into two groups, a treatment group of 46 cases treated with acupuncture, Danshen Zhushe Ye (丹参注射液 Saliva Injection) and routine western drugs and a control group of 42 cases treated simply with drugs. The therapeutic effects were evaluated based on the evaluation criteria for damage of the nerve function. Observation was also made on changes in the skull CT images, and in the activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-px), and nitric oxide synthase (NOS) in serums, and levels of malondialdehyde (MDA) and nitric oxide (NO) in serums. Results: After treatment for 15 days, the total effective rate of the treatment group reached 80.43%, while that of the control group was 61.90%, showing significant differences. The effective rate shown by the skull CT images of the treatment group was 51.61%, while that of the control group was 45.16%, showing no significant differences. But as compared with the control group, the activities of SOD and GSH-px in serums were significantly enhanced, and the levels of MDA and NO, and activity of NOS in serums were significantly decreased in the treatment group. Conclusion: The prompt acupuncture treatment of acute cerebral infarction can markedly raise the clinical therapeutic effects, improve the activity of SOD and GSH-px in serums, lower down the level of MDA in serum, and markedly decrease NO level and NOS activity in serums.

    PurposeDecreased cerebral blood volume is known to be a predictor for final infarct volume in acute cerebral artery occlusion. To evaluate the predictability of final infarct volume in patients with acute occlusion of the middle cerebral artery (MCA) or the distal internal carotid artery (ICA) and successful endovascular recanalization, pooled blood volume (PBV) was measured using flat-panel detector computed tomography (FPD CT).Materials and MethodsTwenty patients with acute unilateral occlusion of the MCA or distal ACI without demarcated infarction, as proven by CT at admission, and successful Thrombolysis in cerebral infarction score (TICI 2b or 3) endovascular thrombectomy were included. Cerebral PBV maps were acquired from each patient immediately before endovascular thrombectomy. Twenty-four hours after recanalization, each patient underwent multislice CT to visualize final infarct volume. Extent of the areas of decreased PBV was compared with the final infarct volume proven by follow-up CT the next day.ResultsIn 15 of 20 patients, areas of distinct PBV decrease corresponded to final infarct volume. In 5 patients, areas of decreased PBV overestimated final extension of ischemia probably due to inappropriate timing of data acquisition and misery perfusion.ConclusionPBV mapping using FPD CT is a promising tool to predict areas of irrecoverable brain parenchyma in acute thromboembolic stroke. Further validation is necessary before routine use for decision making for interventional thrombectomy.

    Purpose: To assess the feasibility and efficacy of catheter-directed thrombolysis with recombinant tissue plasminogen activator (rt-PA) for acute limb embolism in patients with recent cerebral embolism due to atrial fibrillation. Materials and methods: Eight patients (six men, two women; mean age 63.5 years) with acute embolic occlusion of two left common iliac arteries, four femoral arteries (three left; one right), and two right popliteal arteries were treated. All patients had a history of recent cerebral embolism (mean 6 days, range 5-15 days) and all had a history of atrial fibrillation (duration 5-10 years). Catheter-directed thrombolysis started a few hours (mean 6.2 h; range 3-10 h) after the onset of arterial embolism. Two 5 mg boluses of rt-PA were injected into the proximal clot through a 5 F end-hole catheter and, subsequently, two additional boluses of 5 mg rt-PA were injected into the emboli. In patients with residual emboli, infusion with rt-PA (1 mg/h) was continued. Percutaneous transluminal angioplasty was performed in three patients, and a stent was deployed in one patient. Results: Technical success was achieved in all patients. Clinical success rate was 87.5% (7/8). The one clinical failure was secondary to chronic occlusion of outflow runoff vessels. The mean duration of continuous rt-PA infusion was 3.6 h, the mean total dose of rt-PA administered was 23.6 mg (range 20-28 mg). There was no significant change in stroke scale scores during thrombolysis and no intracerebral haemorrhage was found at computed tomography (CT) after thrombolysis. Minor complications included haematomata at puncture sites (6/8), bleeding around the vascular sheath (2/8), and haematuria (1/8). During the follow-up period of 3-6 months, one patient suffered from recurrent cerebral embolism and died. Conclusions: Catheter-directed thrombolysis with rt-PA is an option for acute lower extremity arterial embolism in patients with recent cerebral embolism and a history of

    Carnosine (β-alanyl-L-histidine) is an imidazole dipeptide synthesized in excitable tissues of many animals, whose biochemical properties include carbonyl scavenger, anti-oxidant, bivalent metal ion chelator, proton buffer, and immunomodulating agent, although its precise physiological role(s) in skeletal muscle and brain tissues in vivo remain unclear. The aim of the present study was to investigate the in vivo effects of acute carnosine administration on various aspects of brain bioenergetics of young Wistar rats. The activity of mitochondrial enzymes in cerebral cortex was assessed using a spectrophotometer, and it was found that there was an increase in the activities of complexes I-III and II-III and succinate dehydrogenase in carnosine-treated rats, as compared to vehicle-treated animals. However, quantitative real-time RT-PCR (RT-qPCR) data on mRNA levels of mitochondrial biogenesis-related proteins (nuclear respiratory factor 1 (Nrf1), peroxisome proliferator-activated receptor-γ coactivator 1-α (Ppargc1α), and mitochondrial transcription factor A (Tfam)) were not altered significantly and therefore suggest that short-term carnosine administration does not affect mitochondrial biogenesis. It was in agreement with the finding that immunocontent of respiratory chain complexes was not altered in animals receiving carnosine. These observations indicate that acute carnosine administration increases the respiratory chain and citric acid cycle enzyme activities in cerebral cortex of young rats, substantiating, at least in part, a neuroprotector effect assigned to carnosine against oxidative-driven disorders.

    We present results of a clinical study on bedside perfusion monitoring of the human brain by optical bolus tracking. We measure the kinetics of the contrast agent indocyanine green using time-domain near-IR spectroscopy (tdNIRS) in 10 patients suffering from acute unilateral ischemic stroke. In all patients, a delay of the bolus over the affected when compared to the unaffected hemisphere is found (mean: 1.5 s, range: 0.2 s to 5.2 s). A portable time-domain near-IR reflectometer is optimized and approved for clinical studies. Data analysis based on statistical moments of time-of-flight distributions of diffusely reflected photons enables high sensitivity to intracerebral changes in bolus kinetics. Since the second centralized moment, variance, is preferentially sensitive to deep absorption changes, it provides a suitable representation of the cerebral signals relevant for perfusion monitoring in stroke. We show that variance-based bolus tracking is also less susceptible to motion artifacts, which often occur in severely affected patients. We present data that clearly manifest the applicability of the tdNIRS approach to assess cerebral perfusion in acute stroke patients at the bedside. This may be of high relevance to its introduction as a monitoring tool on stroke units.

  15. REASSESSMENT OF DEFIBRASE IN TREATMENT OF ACUTE CEREBRAL INFARCTION: A MULTICENTER, RANDOMIZED, DOUBLE-BLIND,PLACEBO-CONTROLLED TRIAL

    The Cooperative Group for Reassessment of Defibras

    2005-01-01

    Objective To evaluate the efficacy and safety of defibrase in patients with acute cerebral infarction by a large sample,multicenter, randomized, double-blind, placebo-controlled clinical trial.Methods Patients with acute cerebral infarction within 12 hours of stroke onset were randomly assigned to receive either an initial intravenous infusion of defibrase 15 U plus normal saline 250 Ml or 250 Ml of normal saline only.Subsequent infusions of defibrase 15 U or placebo (normal saline) were given on the 3rd, 5th, 7th, and 9th day, respectively.Both groups received standard care of acute cerebral infarction. The primary efficacy outcome was functional status(Barthel Index) at 3 months after treatment. Safety outcome were bleeding events and mortality rate. Secondary outcome included Chinese Stroke Scale (CSS) score at 14 days and recurrence rate of stroke at 1 year. Results A total of 1053 patients were enrolled at 46 centers from September 2001 to July 2003, and 527 patients were randomly assigned to receive defibrase and 526 to receive placebo. A similar proportion of patients in both groups completed a full course of treatment. There was a significantly greater proportion of favorable functional status (Barthel Index ≥95) in defibrase group than in placebo group at 3 months (52.2% vs. 42.8%, P < 0.01), and the proportion of dependent functional status (Barthel Index ≤60) was a little lower in defibrase group compared with placebo group(27.7%vs. 32.4%). These differences were more obvious among patients who were treated within 6 hours of stroke onset.Patients in defibrase group had better improvement with respect to CSS score than those in placebo group at 14 days (P <0.05). Recurrence rate of stroke at 1 year was lower in the defibrase group compared with placebo group (6.2% vs. 10.1%,P = 0.053). Patients in defibrase group had higher risk of extracranial bleeding events (4.7%vs. 1.5%, P< 0.01) and a tendency of higher risk of symptomatic intracranial hemorrhage

  16. Clinical experience with L-lysine escinate for acute and chronic cerebral circulatory disorders

    N. V. Pizova

    2015-01-01

    Full Text Available Cerebrovascular diseases (CVD are major causes of disability and death in Russia. Stroke is the third significant cause of higher death rates after cardiovascular disease and cancer. The prevalence of circulatory diseases, such as atherosclerosis and hypertension, is on the rise. Therapy for CVD must be aimed at the underlying disease in which vascular catastrophe (atherosclerosis, hypertension, heart disease, etc. develops, at the regression of neurological and psychopathological syndromes, and at the improvement of cerebral blood flow and metabolic processes. Neuroprotective agents, whose efficacy has been established in uncontrolled and small placebo-controlled trials, are widely used in our country. The prescription of these medications is substantiated by the important role of the pathogenetic mechanisms underlying cerebral ischemia. This paper gives data on the clinical use of L-lysine escinate for ischemic stroke (IS, hypertensive crisis, and chronic cerebral circulatory disorders and discusses the mechanism of this drug's action and the pathogenetic mechanisms of cerebrovascular lesions. A number of investigations have shown it expedient to incorporate L-lysine escinate in the combined neuroprotective therapy of patients with IS, cerebral hypertensive crisis, and hypertensive encephalopathy, which is associated with its antiedematous effect, particularly in preventing vasogenic brain edema, in enhancing the tone of cerebral veins, and in improving venous outflow. It is stated that there is a need for an individualized approach to treating CVD, by taking into consideration the existing risk factors and somatic and neurological diseases.

    Background Limited data are available to guide the choice of a target for the systolic blood-pressure level when treating acute hypertensive response in patients with intracerebral hemorrhage. Methods We randomly assigned eligible participants with intracerebral hemorrhage (volume, <60 cm(3)) and a Glasgow Coma Scale (GCS) score of 5 or more (on a scale from 3 to 15, with lower scores indicating worse condition) to a systolic blood-pressure target of 110 to 139 mm Hg (intensive treatment) or a target of 140 to 179 mm Hg (standard treatment) in order to test the superiority of intensive reduction of systolic blood pressure to standard reduction; intravenous nicardipine to lower blood pressure was administered within 4.5 hours after symptom onset. The primary outcome was death or disability (modified Rankin scale score of 4 to 6, on a scale ranging from 0 [no symptoms] to 6 [death]) at 3 months after randomization, as ascertained by an investigator who was unaware of the treatment assignments. Results Among 1000 participants with a mean (±SD) systolic blood pressure of 200.6±27.0 mm Hg at baseline, 500 were assigned to intensive treatment and 500 to standard treatment. The mean age of the patients was 61.9 years, and 56.2% were Asian. Enrollment was stopped because of futility after a prespecified interim analysis. The primary outcome of death or disability was observed in 38.7% of the participants (186 of 481) in the intensive-treatment group and in 37.7% (181 of 480) in the standard-treatment group (relative risk, 1.04; 95% confidence interval, 0.85 to 1.27; analysis was adjusted for age, initial GCS score, and presence or absence of intraventricular hemorrhage). Serious adverse events occurring within 72 hours after randomization that were considered by the site investigator to be related to treatment were reported in 1.6% of the patients in the intensive-treatment group and in 1.2% of those in the standard-treatment group. The rate of renal adverse events

    2017-01-01

    Objective:To explore the clinical efficacy of aspirin in combined with ozagrel sodium in the treatment of acute cerebral infarction (ACI).Methods:A total of 120 patients with ACI who were admitted in our hospital from May, 2015 to May, 2016 were included in the study and randomized into the study group and the control group with 60 cases in each group. The patients in the two groups were given cerebral edema alleviating, brain cell protecting, cerebral circulation improving, and blood pressure controlling. The patients in the study group were given aspirin enteric-coated tablets, 0.1 g/time, 1 time/d. On the above basis, the patients in the study group were given ozagrel sodium (80 mg) + 0.9% NaCl (250 mL), ivdrip, 2 times/d. The patients in the two groups were treated for 14 d. The venous blood was extracted 1 d after admission and 14 d after treatment. The full automatic biochemical analyzer was used to detect PLT, PT, TT, FIB, and APTT. The radioimmunoassay was used to detect TXB2 and 6-K-PGF1α. The color Doppler ultrasound was used to detect IMT.Results: PLT, PT, TT, and APTT after treatment were not significantly different from those before treatment (P>0.05), but FIB was significantly reduced, and the reduced degree in the study group was significantly superior to that in the control group (P<0.05). After treatment, TXB2 level in the two groups was reduced, while 6-K-PGF1α was elevated, and those in the study group were significantly superior to those in the control group (P<0.05). After treatment, IMT in the two groups was reduced, and the reduced degree in the study group was significantly superior to that in the control group (P<0.05).Conclusions:Aspirin in combined with ozagrel sodium in the treatment of ACI can effectively inhibit the platelet aggregation, improve the coagulation function and cerebral blood supply, promote the recovery of cerebral nerve function after infarction, and enhance the therapeutic effect; therefore, it deserves to be widely

    2008-01-01

    BACKGROUND: It has become generally accepted that measuring N-acetyI-L-aspartic acid through the use of 1H-magnetic resonance spectroscopy (1H-MRS) could be used to evaluate neuronal injury. OBJECTIVE: To study metabolic changes of N-acetyl-L-aspanic acid surrounding the acute cerebral ischcmia area following vascular endothelial growth factor (VEGF) treatment using 1H-MRS imaging, and to evaluate the neuroprotective effects of VEGE.DESIGN, TIME AND SETTING: Randomly controlled animal study, according to one-factor analysis of variance, was performed at the Shenzhen Hospital of Peking University and State Key Laboratory of Magnetic Resonance and Atomic and Molecular Physics, Wuhan Institute of Physics and Mathematics, Chinese Academy of Sciences from August 2003 to December 2005.MATERIALS: Twelve healthy, adult, Sprague Dawley rats were used to establish an ischemia/reperfusion model through the use of middle cerebral artery occlusion. The 4.7T superconducting nuclear magnetic resonance meter was provided by Brucker Company. VEGF164 was purchased from Shenzhen Jingmei Bioengineering Co., Ltd. Titus ancsthesia machine was purchased from Draeger Medical AG & Co. KG.METHODS: The rats were randomly divided into model control (n = 6) and VEGF-injected (n = 6) groups. All animals received 60-minute middle cerebral artery occlusion and 24-hour repcrfusion. Lateral cerebral ventricle injection was performed by stereotaxic technique at respective time points.

    Dystroglycan (DG) is widely expressed in various tissues, and throughout the cerebral microvasculature. It consists of two subunits, α-DG and β-DG, and the cleavage of the latter by matrix metalloproteinase (MMP)-2 and -9 underlies a number of physiological and pathological processes. However, the involvement of MMP-2/-9-mediated β-DG cleavage in cerebral ischemia remains uncertain. In astrocytes, DG is crucial for maintaining the polarization of aquaporin-4 (AQP4), which plays a role in the regulation of cytotoxic and vasogenic edema. The present study aimed to explore the effects of MMP-2/-9-mediated β-DG cleavage on AQP4 polarization and brain edema in acute cerebral ischemia. A model of cerebral ischemia was established via permanent middle cerebral artery occlusion (pMCAO) in male C57BL/6 mice. Western blotting, real-time polymerase chain reaction (PCR), immunohistochemical staining, immunofluorescent staining, electron microscopy, and light microscopy were used. Captopril was applied as a selective MMP-2/-9 inhibitor. Recombinant mouse MMP (rmMMP)-2 and -9 were used in an in vitro cleavage experiment. The present study demonstrated evidence of β-DG cleavage by MMP-2/-9 in pMCAO mouse brains; this cleavage was implicated in AQP4 redistribution and brain edema in cerebral ischemia. In addition, captopril exacerbated cytotoxic edema and ameliorated vasogenic edema at 24h after pMCAO, and alleviated brain edema and neurological deficit at 48h and 72h. In conclusion, this study provides novel insight into the effects of MMP-2/-9-mediated β-DG cleavage in acute cerebral ischemia. Such findings might facilitate the development of a therapeutic strategy for the optimization of MMP-2/-9 targeted treatment in cerebral ischemia.

    Reinstrup, Peter; Ryding, Erik Hilmer; Asgeirsson, Bogi;

    2013-01-01

    BACKGROUND: Cerebral blood flow (CBF) measurements are helpful in managing patients with traumatic brain injury (TBI), and testing the cerebrovascular reactivity to CO(2) provides information about injury severity and outcome. The complexity and potential hazard of performing CBF measurements...... limits routine clinical use. An alternative approach is to measure the CBF velocity using bedside, non-invasive, and transcranial Doppler (TCD) sonography. This study was performed to investigate if TCD is a useful alternative to CBF in patients with severe TBI. METHOD: CBF and TCD flow velocity...... measurements and cerebrovascular reactivity to hypocapnia were simultaneously evaluated in 27 patients with acute TBI. Measurements were performed preoperatively during controlled normocapnia and hypocapnia in patients scheduled for hematoma evacuation under general anesthesia. MAIN FINDING AND CONCLUSION...

    1994-02-01

    A 27-year-old woman visited Kanto Teishin Hospital complaining of fever and petechiae in September, 1992. Her fetus had suddenly died in the uterus two weeks before (in the sixth month of pregnancy). Total white blood cell (WBC) count was 3.2 x 10(3)/microliters with 80% promyelocytes. Bone marrow was hypercellular with 90% promyelocytes. Disseminated intravascular coagulation (DIC) was recognized. She was diagnosed as having acute promyelocytic leukemia (APL), and treatment with daily oral administration of all-trans retinoic acid (ATRA) (70 mg/body/day) was begun. On day 4, hemiplegia and aphasia appeared. Broad cerebral infarction was suspected from computed tomography. On day 9, the WBC count increased rapidly, standard chemotherapy was added and she achieved complete remission. ATRA is known to have stimulatory effects on the differentiation of APL cells, but some reports have described thromboembolic events during the administration of ATRA. In this case, ATRA might have affected coagulability resulting in cerebral infarction.

    -induced increase in TNF mRNA production one day after induction of ischemia; however the TNF response to the ischemic insult was affected at five days. SP-D mRNA was not detected in parenchymal brain cells in either naïve mice or in mice subjected to focal cerebral ischemia. However, SP-D mRNA was detected...... were comparable in SP-D KO and WT mice. CONCLUSIONS: SP-D synthesis in middle cerebral artery cells is consistent with SP-D conceivably leaking into the infarcted area and affecting local cytokine production. However, there was no SP-D synthesis in parenchymal brain cells and ablation of SP-D had...

  6. Acute Hemiparesis in a Child as a Presenting Symptom of Hemispheric Cerebral Proliferative Angiopathy

    J. J. Gold

    2013-01-01

    Full Text Available A 9-year-old girl with a several-month history of unilateral intermittent headaches presented to the hospital with worsening headaches and unsteadiness. Neurologic exam was positive for a mild right hemiparesis and right homonymous hemianopsia. Noncontrast computed tomography revealed an engorged sagittal and straight sinus with prominent cortical veins concerning an arteriovenous malformation and the patient was admitted to the pediatric intensive care unit. Computed tomography angiogram demonstrated a left hemispheric vascular malformation, without evidence of dural arteriovenous fistula on conventional angiogram consistent with a diagnosis of cerebral proliferative angiopathy. There was no evidence of infarct on magnetic resonance imaging, and the patient’s symptoms were completely resolved within 24 hours. Cerebral proliferative angiopathy is a rare but important vascular malformation distinct from classic arteriovenous malformations that may present with stroke-like symptoms in childhood.

    Previous studies have focused on the analysis of single or several function-related genes in oxidative stress;however,little information is available regarding altered expression of oxidative stress-related genes in the process of ischemia-reperfusion injury from microarray experiments.The aim of the present study was to investigate the changes in cell oxidative stress-and toxicity-related gene expression utilizing microarray screening in patients with acute cerebral infarction during cerebral ischemia-reperfusion injury.Of the included 114 genes,expression was significantly upregulated in eight genes,including three heat shock protein-related genes,one oxidative and metabolic stress-related gene,one cell growth arrest/senescence related gene,two apoptosis signal-related genes,and one DNA damage and repair related gene.Expression was significantly downregulated in four genes,including one cell proliferation/cancer related gene,two oxidative and metabolic stress-related genes and one DNA damage and repair related gene.The results demonstrated that cerebral ischemia-reperfusion injury in patients with acute cerebral infarction was affected by many genes including oxidative stress-,heat shock-,DNA damage and repair-,and apoptosis signal-related genes.Therefore,it could be suggested that cerebral ischemia-reperfusion injury may be subjected to complex genetic regulation mechanisms.

    Moscote-Salazar, Luis Rafael; Alcalá-Cerra, Gabriel; Castellar-Leones, Sandra Milena; Gutiérrez-Paternina, Juan José

    2013-01-01

    Introducción: la otitis media aguda es una inflamación del oído medio frecuente en la edad pediátrica. Aproximadamente 2 % de todos los casos desarrolla complicaciones intracraneales, más específicamente meningitis; por lo general, los infartos cerebrales originados por esta última son venosos. Rara vez se ha descrito la ocurrencia de un infarto arterial cerebral como complicación directa de la otitis media aguda. Caso clínico: niña de 12 meses de edad quien fue llevada a un servicio de urgencias por síndrome febril secundario a otitis media aguda y alteración del estado de conciencia. A la exploración física se identificó que estaba somnolienta, con anisocoria, midriasis en el ojo derecho y hemiparesia izquierda. Con la tomografía axial computarizada de cerebro se apreció un infarto arterial cerebral extenso. Los padres no autorizaron la craniectomía descompresiva y la paciente falleció a las 48 horas de su ingreso hospitalario. Conclusiones: a pesar de los recursos tecnológicos con los que se dispone actualmente, el infarto cerebral relacionado con la otitis media aguda tiene una evolución tórpida. Los signos neurológicos focalizadores y el deterioro progresivo deben apuntar a la ineficacia del tratamiento antimicrobiano instaurado.

  10. Hypersensitivity to thromboxane receptor mediated cerebral vasomotion and CBF oscillations during acute NO-deficiency in rats.

    Béla Horváth

    Full Text Available BACKGROUND: Low frequency (4-12 cpm spontaneous fluctuations of the cerebrovascular tone (vasomotion and oscillations of the cerebral blood flow (CBF have been reported in diseases associated with endothelial dysfunction. Since endothelium-derived nitric oxide (NO suppresses constitutively the release and vascular effects of thromboxane A(2 (TXA(2, NO-deficiency is often associated with activation of thromboxane receptors (TP. In the present study we hypothesized that in the absence of NO, overactivation of the TP-receptor mediated cerebrovascular signaling pathway contributes to the development of vasomotion and CBF oscillations. METHODOLOGY/PRINCIPAL FINDINGS: Effects of pharmacological modulation of TP-receptor activation and its downstream signaling pathway have been investigated on CBF oscillations (measured by laser-Doppler flowmetry in anesthetized rats and vasomotion (measured by isometric tension recording in isolated rat middle cerebral arteries, MCAs both under physiological conditions and after acute inhibition of NO synthesis. Administration of the TP-receptor agonist U-46619 (1 µg/kg i.v. to control animals failed to induce any changes of the systemic or cerebral circulatory parameters. Inhibition of the NO synthesis by nitro-L-arginine methyl ester (L-NAME, 100 mg/kg i.v. resulted in increased mean arterial blood pressure and a decreased CBF accompanied by appearance of CBF-oscillations with a dominant frequency of 148±2 mHz. U-46619 significantly augmented the CBF-oscillations induced by L-NAME while inhibition of endogenous TXA(2 synthesis by ozagrel (10 mg/kg i.v. attenuated it. In isolated MCAs U-46619 in a concentration of 100 nM, which induced weak and stable contraction under physiological conditions, evoked sustained vasomotion in the absence of NO, which effect could be completely reversed by inhibition of Rho-kinase by 10 µM Y-27632. CONCLUSION/SIGNIFICANCE: These results suggest that hypersensitivity of the TP

    Luo ZuMing; Xiong Hai

    2000-01-01

    Objectives: To investigate whether early rchabilitation could improve obviously clinical prognosis of acute stroke patients. The mechanism of early rehabilitation that could improve brain function was preliminarily studied. Methods: 240 patients with acute hemiplegia were randomly divided into control group (120 cases) and rehabilitation group (120 cases). The control group received general treatment and the latter received early rehabilitation (Bobath methods) besides general treatment. At pre-rehabilitation and the end of 1,2,3,4,5,6 month at post-rehabilitation, the neurological deficit was assessed with modified Edinbcrg-Scandinavian stroke scale (MESSS); the motor function of the hemiplegic limbs were assessed with modified Fugl-meyer motor scale (FM);the ADL were assessed with modified Barthel Index (MBI), and the general secondary complications of both groups were also evaluated. Moreover, rCBF of 72 cases of acute cerebral infarction with hemiplegia (34 in control group, 38 in rehabilitation group) was earned out by SPECT imaging at pre-rehabilitation and at the end of I month at post - rehabilitation.Results and Discussion: Compared with those of control group, at the end of 1,2,3,4,5,6 month at post - rehabilitation, the scores of MESSS were more obviously decreased (p<0.05 and p<0.01); the scores of MBI and FM were more significantly increased (p<0.05 and p<0.01); and morbidity of secondary complications was more significantly decreased (p<0.05 and p<0.01). Compared with those of pre-rehabilitation in rehabilitation group, both the decrease of MESS scores and the increase of FM, MBI scores were more obvious (p<0.01) at the end of 1,2,3 month of post-rehabilitation; however, compared with that of the end of 3 month at post-rehabilitation, at the end of 4,5,6 month of post-rehabilitation in rehabilitation group. Both the decrease of MESSS scores and the increase of FM scores hadn′t statistical significance (p>0.05). but scores of MBt were

  13. Influence of acetyl-carnitine on some mitochondrial enzymic activities in the human cerebral tissue in conditions of acute hypoxia.

    Corbucci, G G; Melis, A; Piga, M; Marchionni, A; Calvani, M

    1992-01-01

    Following previous research on human tissue in conditions of acute and massive hypoxia, in the present work the authors compared the cellular enzymic response to oxidative stress in normoxic (perifocal) and hypoxic (focal) areas in human brain affected by regional acute vasculopathies. Two homogeneous groups of patients were selected following strict clinical inclusion/exclusion criteria. The groups of patients were treated with a placebo or acetyl-carnitine at same doses and following randomized, double-blind procedures. The focal areas showed a significant functional damage in lactate, pyruvate and succinate dehydrogenases and in the cytochrome oxidase activity when compared with the enzymic capacities of perifocal areas (normoxic as controls). The pretreatment with acetyl-carnitine antagonized the above-mentioned enzymic damage by a protective action linked to the endocellular energy restoration. In accordance with these data, the therapeutic role played by acetyl-carnitine in the cerebral focal hypoxia appeared to be a determinant for the cell survival mainly in the reversible phase of oxidative damage.

  14. Cerebral hemodynamic changes of mild traumatic brain injury at the acute stage.

    Hardik Doshi

    Full Text Available Mild traumatic brain injury (mTBI is a significant public health care burden in the United States. However, we lack a detailed understanding of the pathophysiology following mTBI and its relation to symptoms and recovery. With advanced magnetic resonance imaging (MRI, we can investigate brain perfusion and oxygenation in regions known to be implicated in symptoms, including cortical gray matter and subcortical structures. In this study, we assessed 14 mTBI patients and 18 controls with susceptibility weighted imaging and mapping (SWIM for blood oxygenation quantification. In addition to SWIM, 7 patients and 12 controls had cerebral perfusion measured with arterial spin labeling (ASL. We found increases in regional cerebral blood flow (CBF in the left striatum, and in frontal and occipital lobes in patients as compared to controls (p = 0.01, 0.03, 0.03 respectively. We also found decreases in venous susceptibility, indicating increases in venous oxygenation, in the left thalamostriate vein and right basal vein of Rosenthal (p = 0.04 in both. mTBI patients had significantly lower delayed recall scores on the standardized assessment of concussion, but neither susceptibility nor CBF measures were found to correlate with symptoms as assessed by neuropsychological testing. The increased CBF combined with increased venous oxygenation suggests an increase in cerebral blood flow that exceeds the oxygen demand of the tissue, in contrast to the regional hypoxia seen in more severe TBI. This may represent a neuroprotective response following mTBI, which warrants further investigation.

    2014-01-01

    A 37-year-old woman presented with psychiatric symptoms. Cerebrospinal fluid analysis revealed pleocytosis and increased protein. The patient was diagnosed with limbic encephalitis on the basis of the clinical course. However, remarkable hyponatremia was noted throughout the clinical course, leading to a diagnosis of cerebral salt wasting syndrome (CSWS). The hyponatremia was alleviated by supplementation with sodium and water. The findings seen in this case indicate that differentiation between syndrome of inappropriate of antidiuretic hormone and CSWS is important in cases of hyponatremia accompanied by central nervous system disease.

    Background Coagulation factor Ⅶ (F Ⅶ) levels in plasma are usually related to ischemic heart disease (IHD) and cerebral infarction shares many of the risk factors related to IHD. Is there any relationship between factor Ⅶ and cerebral infarction? We investigated the relationship between F Ⅶ and acute cerebral infarction and reported genotype frequencies and allelic frequencies of FⅦ gene polymorphisms in the Chinese Han population.Methods We recruited 62 patients with acute cerebral infarction confirmed by magnetic resonance imaging (MRI) from Ruijin Hospital, and 149 age-matched patients clinically free of vascular disease to act as controls. All of them were unrelated, and were from the Chinese Han population. FⅦ coagulant activity (FⅦc) was determined using an clotting assay, activated FⅦ (FⅦa) and FⅦ Ag were assayed using enzyme immunoassay kits. The FⅦ gene polymorphisms to be detected included-401G/T, -402G/A, 5'F7A1/A2, IVS7 and R353Q. 5'F7 and IVS7 were revealed by means of a PCR and direct agarose gel electrophoresis. The rest were examined by a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Results The results showed that FⅦc, FⅦAg and FⅦa were higher in the acute cerebral infarction group than in the control group (P<0.01, P<0.05, P<0.05, respectively). There were no significant differences in the genotype frequencies of FⅦ gene polymorphisms between the two groups. The allelic frequencies in the Chinese Han population were as follows: -401G/T (96.64/3.36), -402G/A (52.01/47.99), 5'F7A1/A2(96.64/3.36), IVS7 H5/H6/H7/H8 (0.34/52.35/46.98/0.34) and R353Q (95.64/4.36). There were significant differences (P<0.01, P<0.001, P<0.001, P<0.001, P<0.001, respectively) in these allelic frequencies between the Chinese Han and European populations.Conclusions The results indicate that increased plasma FⅦ levels may contribute to thrombosis in cerebral infarction. And there was no significant difference

    2017-01-01

    Objective:To analyze the effect of fasudil combined with conventional therapy on nerve and blood coagulation function as well as Hcy metabolism in patients with acute cerebral infarction. Methods:80 patients with acute cerebral infarction treated in our hospital between January 2013 and January 2013 were selected as the research subjects and divided into observation group (n = 40) and control group (n = 40) according to the random number table. Control group received conventional therapy and observation group received fasudil combined with conventional therapy. After 14 d of treatment, the levels of cerebral blood perfusion parameters, nerve function indexes, platelet function indexes and homocysteine (Hcy) of two groups of patients were determined.Results:After 14 d of treatment, middle cerebral artery and basilar artery peak systolic flow velocity (Vs), low diastolic flow velocity (Vd) and mean flow velocity (Vm) levels of observation group were higher than those of control group (P<0.05); serum nerve function indexes brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) content were higher than those of control group (P<0.05) while phosphatidic acid (PA), neuron-specific enolase (NSE), S100β protein (S100β), and substantia nigra divalent metal transporter 1 (DMT1) content were lower than those of control group (P<0.05); serum platelet function indexes platelet activation-dependent granule membrane protein-140 (GMP-140), fibrinogen receptor-1 (PAC-1), platelet activating factor (PAF) and platelet-derived growth factor BB (PDGF-BB) content were lower than those of control group (P<0.05); serum Hcy content was lower than that of control group (P<0.05).Conclusions:Fasudil combined with conventional therapy can optimize the nerve function and blood coagulation function in patients with acute cerebral infarction, and also plays a positive role in reducing Hcy levels.

  19. Cerebral haemodynamic response to acute intracranial hypertension induced by head-down tilt.

    Bosone, Daniele; Ozturk, Vesile; Roatta, Silvestro; Cavallini, Anna; Tosi, Piera; Micieli, Giuseppe

    2004-01-01

    The aim of this study was to evaluate, in a context of general inhibition of the sympathetic nervous system, the cerebral haemodynamic response to -30 degrees head-down tilt (HDT), a manoeuvre that produces an increase in intracranial arterial pressure. Nineteen healthy subjects were studied according to the following protocol: 10 min lying in supine position, 10 min HDT, 10 min recovery. Inhibition of the sympathetic system was confirmed by the decrease in heart rate (-3.6 bpm) and arterial blood pressure (-5.9 mmHg, p<0.05) in the late phase of the test. Blood velocity and blood pusatility index initially increased (+3.2 cm s(-1) and +9% respectively, p<0.01) then returned towards baseline before the end of HDT, while the cerebrovascular resistance index (=arterial blood pressure/blood velocity) dropped significantly and remained below control level (-7%, p<0.01) throughout the test. The changes in both these indices were opposite to those reported in several sympathetic activation tests, such as the handgrip and cold pressor tests. Conversely, arterial pressure at cranial level increased during HDT (as it also does during sympathetic activation tests), due to the development of a hydrostatic pressure gradient between heart and brain levels. Therefore, the effects observed on the pulsatility and resistance indices are not secondary to the increase in intracranial arterial pressure. It is suggested that the changes in these cerebrovascular indices are mediated by a reduction of sympathetic tone that presumably involves the cerebral as well as the peripheral vascular bed.

    1987-05-01

    Single photon emission computed tomography (SPECT) with xenon-133 inhalation method was undertaken within 48 hr after the onset in 68 patients with ischemic cerebrovascular disease. The results for regional cerebral blood flow (rCBF) were compared with concurrently available computed tomography (CT) scans. In patients with cerebral infarction, SPECT detected ischemic lesions earlier than CT, with the detectability being 92 %. The area with a decreased blood flow, as seen on SPECT, was more extensive than the low density area on CT, with a concomitant decrease in blood flow in the contralateral cerebral hemisphere. Crossed cerebellar diaschisis was associated with stenosis of the internal carotid artery in 50 % (7/14), and with stenosis of the middle cerebral artery in 35 % (9/26). Abnormal SPECT findings were seen in 47 % (8/17) of the patients with transient ischemic attack (TIA). Five TIA patients had a decreased rCBF on SPECT, which was not provided by CT scans. On the contrary, small infarct lesions in the cerebral basal ganglia, as observed in 4 patients, was not detected by SPECT, but detected by CT. This may imply the limitations of SPECT in the detection of deep-seated lesions of the cerebrum. The results led to the conclusion that SPECT can be performed safely even in acute, seriously ill patients to know changes in rCBF because it is noninvasive and is capable of being repeated in a short time.

    Cohen, José E; Gomori, John M; Moscovici, Samuel; Itshayek, Eyal

    2012-03-01

    The complex anatomic features of wide-necked anterior communicating artery aneurysms represent an endovascular challenge. Compliant balloons and microstents are frequently required to achieve aneurysm occlusion. When the angle between the A1 and A2 segments is acute, microcatheter navigation is hazardous, and may be difficult or sometimes impossible with standard techniques. We present our technique using a support balloon to facilitate guidewire engagement and navigation of A2, and to assist with microcatheterization in this unfavorable vascular anatomy.

  2. Effects of Repetitive Hyperbaric Oxygen Treatment in Patients with Acute Cerebral Infarction: A Pilot Study

    Cheng-Hsin Chen

    2012-01-01

    Full Text Available The role of hyperbaric oxygen therapy (HBOT in the treatment of acute ischemic stroke is controversial. This prospective study assessed the efficacy and safety of HBOT as adjuvant treatment on 46 acute ischemic stroke in patients who did not receive thrombolytic therapy. The HBOT group (n=16 received conventional medical treatment with 10 sessions of adjunctive HBOT within 3–5 days after stroke onset, while the control group (n=30 received the same treatment but without HBOT. Early (around two weeks after onset and late (one month after onset outcomes (National Institutes of Health Stroke Scale, NIHSS scores and efficacy (changes of NIHSS scores of HBOT were evaluated. The baseline clinical characteristics were similar in both groups. Both early and late outcomes of the HBOT group showed significant difference (P≤0.001. In the control group, there was only significant difference in early outcome (P=0.004. For early efficacy, there was no difference when comparing changes of NIHSS scores between the two groups (P=0.140 but there was statistically significant difference when comparing changes of NIHSS scores at one month (P≤0.001. The HBOT used in this study may be effective for patients with acute ischemic stroke and is a safe and harmless adjunctive treatment.

  3. Translational neurochemical research in acute human brain injury: the current status and potential future for cerebral microdialysis.

    Hillered, Lars; Vespa, Paul M; Hovda, David A

    2005-01-01

    applications need additional validation. Although these cerebral events and their corresponding changes in neurochemistry are important, other promising MD applications, as yet less explored, comprise local neurochemical provocations, drug penetration to the human brain, MD as a tool in clinical drug trials, and for studying the proteomics of acute human brain injury. Nevertheless, MD has provided new important insights into the neurochemistry of acute human brain injury. It remains one of very few methods for neurochemical measurements in the interstitial compartment of the human brain and will continue to be a valuable translational research tool for the future. Therefore, this technology has the potential of becoming an established part of multimodality neuro-ICU monitoring, contributing unique information about the acute brain injury process. However, in order to reach this stage, several issues related to quantification and bedside presentation of MD data, implantation strategies, and quality assurance need to be resolved. The future success of MD as a diagnostic tool in clinical neurosurgery depends heavily on the choice of biomarkers, their sensitivity, specificity, and predictive value for secondary neurochemical events, and the availability of practical bedside methods for chemical analysis of the individual markers. The purpose of this review was to summarize the results of clinical studies using cerebral MD in neurosurgical patients and to discuss the current status of MD as a potential method for use in clinical decision-making. The approach was to focus on adverse neurochemical conditions in the injured human brain and the MD biomarkers used to study those events. Methodological issues that appeared critical for the future success of MD as a routine intracerebral sampling method were addressed.

    Early transcranial Doppler (TCD) screening of the Créteil sickle cell anemia (SCA)-newborn cohort, and rapid initiation of transfusion programs, resulted in successful prevention of overt strokes, but a high cumulative risk of silent cerebral infarcts (SCI) remained, suggesting that TCD screening does not identify all patients with SCA at risk for SCI. We hypothesized that episodes of hypoperfusion/hypoxia, as observed during acute chest syndromes or acute anemic events (AAE), and extracranial internal carotid artery (eICA) stenoses, detectable via submandibular Doppler sonography and cervical magnetic resonance angiography (MRA), could also be risk factors for SCI. This study includes 189 stroke-free patients with SCA from the Créteil newborn cohort (1992-2010) followed longitudinally by magnetic resonance imaging/MRA, including cervical MRA at the last assessment. All patients with abnormal TCD and/or intracranial stenoses were placed on a transfusion program. Mean follow-up was 9.9 years (range, 2.2-19.9 years; 1844 patient-years). Annual rates of clinical events were calculated. The cumulative risk for SCI was 39.1% (95% confidence interval [CI], 23.5%-54.7%) by age 18 years, with no plateau. We confirm that baseline hemoglobin level lower than 7 g/dL before age 3 years is a highly significant predictive risk factor for SCI (hazard ratio, 2.97; 95% CI, 1.43-6.17; P = .004). Furthermore, we show that AAE rate (odds ratio, 2.64 per unit increase; 95% CI, 1.09-6.38; P = .031) and isolated eICA stenosis (odds ratio, 3.19; 95% CI, 1.18-8.70; P = .023) are significant and independent risk factors for SCI.

    BACKGROUND: Glutathione, as an in vivo free radical scavenger, plays an important role in the anti-oxidation defense mechanism in patients with acute cerebral infarction.OBJECTIVE: To observe the relationship between the levels of glutathione (GSH) and malonaldehyde (MDA), the metabolite of lipid peroxidation, in erythrocyte and deformation index of erythrocyte in patients at various periods following acute cerebral infarction.DESIGN : Controlled observation.SETTING: Qilu Hospital of Shandong University and Institute of Cerebrovascular Disease of Qingdao Medical College.PARTICIPANTS: We chose 98 inpatients with acute cerebral infarction from Department of Neurology, Qilu Hospital of Shandong University from January to December 2000 , serving as cerebral infarction group, including 50 male and 48 female , with mean age of (62±7)years. There were 23 cases found on the 1st day after onset; 25 cases on the 3rd day after onset; 25 cases on the 7th day after onset; 25 cases on the 14th days after onset, and they were all confirmed by craniocerebral CT or MRI. Another 30 homeochronous inpatients with neurosis, cervical syndrome, lumbar intervertebral disc herniation and motor neuron disease were chosen as control group, including 20 male and 10 female, with mean age of (52±8)years . There was no significant difference in age and gender distribution between two groups (P > 0.05). Patients in the two groups were informed of detected index.METHODS: ①Ulnar venous blood was chosen from the patients who were fasted on the 1st, 3rd, 7th and 14th days after onset. Deformation index of erythrocyte was measured with BL88-CKX laser diffraction erythrocyte deformeter and photographing was performed. GSH level in erythrocyte was measured with DTNB assay introduced by Beu-tler. MDA level in erythrocyte was measured with modified thiobarbituric acid colorimetric method. ②At each sample collecting , according to the criteria accepted by the Fourth National Conference of

    In 120 patients with atherosclerosis, complicated in 43 patients by a haemorrhagic, in 47 patients by an ischaemic, and in 30 patients by a transient cerebral insult, phase analysis of platelet aggregation was performed by the turbidimetric method according to Born with graphic recording according to O'Brien. An increase in the platelet activity was found in ischaemic insult, manifesting itself by the occurrence of spontaneous aggregationin 60% of the cases, an acceleration of ADP-induced aggregation, and the second aggregation phase in all patients examined. A direct correlation was revealed between the secondary aggregation and the intensity of spontaneous and of ADP-induced aggregation, and the possibility of a transformation of the spontaneous into the secondary aggregation of platelets was demonstrated. Haemorrhagic insults were characterized by the absence of spontaneous and secondary aggregation and by the suppression of ADP-induced aggregation. In a transient insult, the mean values of the aggregatogram items did differ from normal. In vitro, the role of increased permeability of platelet membranes in the mechanism triggering off spontaneous aggregation and the second phase of ADP-induced aggregation was documented.

    2012-01-01

    Administration of erythropoietin (EPO) has been linked to cerebrovascular events. EPO reduces vascular conductance, possibly because of the increase in hematocrit. Whether EPO in itself affects the vasculature remains unknown; here it was evaluated in healthy males by determining systemic...... and cerebrovascular variables following acute (30,000 IU/d for 3 d; n=8) and chronic (5000 IU/week for 13 wk; n=8) administration of EPO, while the responsiveness of the vasculature was challenged during cycling exercise, with and without hypoxia. Prolonged administration of EPO increased hematocrit from 42.5 ± 3...

    2013-05-01

    We investigated whether real-time ultrasound perfusion imaging (rt-UPI) is able to detect perfusion changes related to arterial recanalization in the acute phase of middle cerebral artery (MCA) stroke. Twenty-four patients with acute territorial MCA stroke were examined with rt-UPI and transcranial color-coded duplex ultrasound (TCCD). Ultrasound studies were consecutively performed within 24 h and 72-96 h after stroke onset. Real-time UPI parameters of bolus kinetics (time to peak, rt-TTP) and of refill kinetics (plateau A and slope β of the exponential replenishment curve) were calculated from regions of interest of ischemic versus normal brain tissue; these parameters were compared between early and follow-up examinations in patients who recanalized. At the early examination, there was a delay of rt-TTP in patients with MCA occlusion (rt-TTP [s]: 13.09 ± 3.21 vs. 10.16 ± 2.6; p = 0.01) and a lower value of the refill parameter β (β [1/s]: 0.62 ± 0.34 vs. 1.09 ± 0.58; p = 0.01) in ischemic compared with normal brain tissue, whereas there were no differences of the parameters A and Axβ. At follow-up, the delay of rt-TTP was reversible once recanalization of an underlying MCA obstruction was demonstrated: rt-TTP [s], 13.09 ± 3.21 at 24 h versus 10.95 ± 1.5 at 72-96 h (p = 0.03). Correspondingly, β showed a higher slope than at the first examination: β [1/s]: 0.55 ± 0.29 at 24 h versus 0.71 ± 0.27 at 72-96 h (p = 0.04). We conclude that real-time UPI can detect hemodynamic impairment in acute MCA occlusion and subsequent improvement following arterial recanalization. This offers the chance for bedside monitoring of the hemodynamic compromise (e.g. during therapeutic interventions such as systemic thrombolysis).

    2016-01-01

    Objective: To study the correlation of serum monocyte chemotactant protein-1 (MCP-1) and vascular endothelia cadherin (VE-cadherin) levels in patients with acute cerebral infarction, and nerve injury molecules, interleukins and matrix metalloproteinases. Methods: A total of 86 patients with acute cerebral infarction treated in our hospital from April 2012 to October 2015 were selected as the observation group and 50 healthy subjects in the same period treated in our hospital were selected as the control group. The serums were collected and the contents of MCP-1, VE-cadherin, heart-type fatty acid binding protein (H-FABP), S100 calcium binding protein B (S100B), neuron-specific enolase (NSE), interleukin-lb (IL-1b), IL-6, IL-17, IL-18, matrix metalloproteinase-2 (MMP2), MMP3 and MMP9 were measured. Results: The serum contents of MCP-1, VE-cadherin, H-FABP, S100B, NSE, IL-1b, IL-6, IL-17, IL-18, MMP2, MMP3 and MMP9 in observation group were significantly higher than those of control group. Carotid artery plaque formation and unstable plaque properties will increase the serum contents of MCP-1, VE-cadherin, H-FABP, S100B, NSE, IL-1b, IL-6, IL-17, IL-18, MMP2, MMP3 and MMP9 in patients with cerebral infarction. The serum levels of MCP-1, VE-cadherin and the contents of H-FABP, S100B, NSE, IL-1b, IL-6, IL-17, IL-18, MMP2, MMP3 and MMP9 were positively correlated. Conclusions: The serum levels of VE-cadherin and MCP-1 were significantly increased in patients with acute cerebral infarction. MCP-1 and VE-cadherin can increase the secretion of interleukins and matrix metalloproteinases, which can result in the carotid artery plaque formation, unstable plaque properties and the injury of nerve function.

    1975-01-01

    An investigation was made of the effects of phenothiazine medication on the averaged visual-evoked potentials (AVEP) and on eye movements in hospitalized, young, acute schizophrenic patients. These results were compared with those of normal subjects who were not given medication. AVEP measures included maximum amplitude (Am), frequency of peaks (FOP'S), variability (V) and peak latencies for an early negative peak (N1) and a later positive peak (P6). Eye movement measures included percent of time looking at a stimulus slide, percent of time looking at a figure on the slide, the number of fixations and the percent of cells entered in which fixations occurred. For schizophrenics off and on phenothiazine medication, there were no consistently significant drug effects on any measure except frequency of peaks. Schizophrenics compared to normals had lower amplitudes, greater frequency of peaks, greater variability and lower eye movement scores.

  13. Effect of extracranial electric stimulation at cerebellar fastigial nucleus on serum C-reactive protein of patients with acute cerebral infarction

    2007-01-01

    BACKGROUND: Some reports indicate that electric and/or chemical stimulation at various brain sites of experimental animals can raise regional cerebral blood flow and improve cerebral circulation; however, its mechanism is still unclear.OBJECTIVE: To observe the effects of electric stimulation at cerebellar fastigial nucleus on serum C-reactive protein of patients with acute cerebral infarction.DESIGN: Non-randomized synchronized contrast study.SETTING: The Second People's Hospital of Xinxiang City.PARTICIPANTS: A total of 54 patients with acute cerebral infarction were selected from the Department of Neurology, the Second People's Hospital of Xinxiang from December 2005 to December 2006. There were 31 males and 23 females, and their ages ranged from 56 to 80 years. All patients met the diagnostic criteria of the Fourth National Cerebrovascular Academic Meeting, were finally diagnosed by using CT examination,and provided the confirmed consent. Based on therapeutic demands, patients were divided into electric stimulation group and routine treatment group with 27 cases in each group. In addition, 21 healthy subjects,including 11 males and 10 females and aging 53 - 78 years, were selected as the control group. All the subjects in the control group did not have any histories of cerebrovascular diseases and severe body diseases.METHODS: Based on routine drug therapy, patients in the electric stimulation group were also treated by using CVFT-010M cerebral circulation function therapeutic device (made in Shanghai). Electrode was fixed at bilateral mastoid in the first group and at extensible sides of upper limbs in the second group. Electric stimulation was given twice a day and lasted for 30 minutes each time.

    Ali Seifi

    Full Text Available OBJECTIVES: To determine the association between myocardial infarction (AMI and clinical outcome in patients with primary admissions diagnosis of acute cerebral ischemia (ACI in the US. METHODS: Data from Nationwide Inpatient Sample (NIS was queried from 2002-2011 for inpatient admissions of patients with a primary diagnosis of ACI with and without AMI using International Classification of Diseases, Ninth Revision, Clinical Modification coding (ICD-9. A multivariate stepwise regression analysis was performed to assess the correlation between identifiable risk factors and clinical outcomes. RESULTS: During 10 years the NIS recorded 886,094 ACI admissions with 17,526 diagnoses of AMI (1.98%. The overall cumulative mortality of cohort was 5.65%. In-hospital mortality was associated with AMI (aOR 3.68; 95% CI 3.49-3.88, p≤0.0001, rTPA administration (aOR 2.39 CI, 2.11-2.71, p<0.0001, older age (aOR 1.03, 95% CI, 1.03-1.03, P<0.0001 and women (aOR 1.06, 95% CI 1.03-1.08, P<0.0001. Overall, mortality risk declined over the course of study; from 20.46% in 2002 to 11.8% in 2011 (OR 0.96, 95% CI 0.95-0.96, P<0.0001. Survival analysis demonstrated divergence between the AMI and non-AMI sub-groups over the course of study (log-rank p<0.0001. CONCLUSION: Our study demonstrates that although the prevalence of AMI in patients hospitalized with primary diagnosis of ACI is low, it negatively impacts survival. Considering the high clinical burden of AMI on mortality of ACI patients, a high quality monitoring in the event of cardiac events should be maintained in this patient cohort. Whether prompt diagnosis and treatment of associated cardiovascular diseases may improve outcome, deserves further study.

    Stroke is a devastating disease. The changes in cerebral hemodynamics and oxygen metabolism associated with stroke play an important role in pathophysiology study. But the changes were difficult to describe with a single imaging modality. Here the changes in cerebral blood flow (CBF), cerebral blood volume (CBV), and oxygen saturation (SO2) were yielded with laser speckle imaging (LSI) and photoacoustic microscopy (PAM) during and after 3-h acute focal ischemic rats. These hemodynamic measures were further synthesized to deduce the changes in oxygen extraction fraction (OEF). The results indicate that all the hemodynamics except CBV had rapid declines within 40-min occlusion of middle cerebral artery (MCAO). CBV in arteries and veins first increased to the maximum value of 112.42±36.69% and 130.58±31.01% by 15 min MCAO; then all the hemodynamics had a persistent reduction with small fluctuations during the ischemic. When ischemia lasted for 3 h, CBF in arteries, veins decreased to 17±14.65%, 24.52±20.66%, respectively, CBV dropped to 62±18.56% and 59±18.48%. And the absolute SO2 decreased by 40.52±22.42% and 54.24±11.77%. After 180-min MCAO, the changes in hemodynamics and oxygen metabolism were also quantified. The study suggested that combining LSI and PAM provides an attractive approach for stroke detection in small animal studies.

    BACKGROUND: Thrombus precursor protein (TpP) is the index of thrombus activity level, and it is also early referencing index in detecting thrombus diseases.OBJECTIVE: To dynamically observe the changes of TpP level in blood plasma of patients with acute cerebral infarction at different time after onset, and to compare the differences of plasma TpP level between patients with acute cerebral infarction and healthy persons who received health examination.DESIGN: Controlled observation.SETTING: Department of Neurology, Affiliated Hospital of Xuzhou Medical College.PARTICIPANTS: Totally 58 patients with acute cerebral infarction who received the treatment in the Department of Neurology, Affiliated Hospital of Xuzhou Medical College between September 2004 and March 2005 were recruited in this study. They all met the diagnostic criteria revised by the 4th National Conference of Cerebrovascular Disorders in 1995 and were diagnosed by clinical and skull CT and (or) MRI examinations. The patients included 33 male and 25 female aged from 36 to 87 years. Time to onset < 6 hours, 6 to 11 hours, 12 to 23 hours, 24 to 48 hours and > 48 hours were found in 10,11,14,10 and 13 patients respectively. Another 51 persons who homeochronously received the health body examination in our hospital were recruited, including 34 male and 17 female, aged 38 to 85 years, serving as control group. Patients with cardio-cerebrovascualr diseases or liver and kidney diseases were excluded. All the involved subjects were informed of the detected items.METHODS: About 4 mL venous blood was respectively taken from patients admitted to the hospital within 6 hours, 6 to11 hours, 12 to 23 hours, 24 to 48 hours and more then 48 hours after onset, and healthy persons when receiving health examination. The level of TpP in blood plasma was measured with enzymelinked immunosorbent assay.MAIN OUTCOME MEASURES: ① Comparison of the level of plasma TpP between patients and controls; ② Comparison of the level

    Central nervous system (CNS) antibiotic distribution was described mainly from cerebrospinal fluid data, and only few data exist on brain extracellular fluid concentrations. The aim of this study was to describe brain distribution of cefotaxime (2 g/8 h) by microdialysis in patients with acute brain injury who were treated for a lung infection. Microdialysis probes were inserted into healthy brain tissue of five critical care patients. Plasma and unbound brain concentrations were determined at steady state by high-performance liquid chromatography. In vivo recoveries were determined individually using retrodialysis by drug. Noncompartmental and compartmental pharmacokinetic analyses were performed. Unbound cefotaxime brain concentrations were much lower than corresponding plasma concentrations, with a mean cefotaxime unbound brain-to-plasma area under the curve ratio equal to 26.1 ± 12.1%. This result was in accordance with the brain input-to-brain output clearances ratio (CL(in,brain)/CL(out,brain)). Unbound brain concentrations were then simulated at two dosing regimens (4 g every 6 h or 8 h), and the time over the MICs (T>MIC) was estimated for breakpoints of susceptible and resistant Streptococcus pneumoniae strains. T>MIC was higher than 90% of the dosing interval for both dosing regimens for susceptible strains and only for 4 g every 6 h for resistant ones. In conclusion, brain distribution of cefotaxime was well described by microdialysis in patients and was limited.

    Objectives: To assess the accuracy and reliability of one vendor's (Vital Images, Toshiba Medical, Minnetonka, MN) automated CT perfusion (CTP) summary maps in identification and volume estimation of infarcted tissue in patients with acute middle cerebral artery (MCA) distribution infarcts. Subjects and methods: From 1085 CTP examinations over 5.5 years, 43 diffusion-weighted imaging (DWI)-positive patients were included who underwent both CTP and DWI <12 h after symptom onset, with another 43 age-matched patients as controls (DWI-negative). Automated delay-corrected postprocessing software (DC-SVD) generated both infarct “core only” and “core + penumbra” CTP summary maps. Three reviewers independently tabulated Alberta Stroke Program Early CT scores (ASPECTS) of both CTP summary maps and coregistered DWI. Results: Of 86 included patients, 36 had DWI infarct volumes ≤70 ml, 7 had volumes >70 ml, and 43 were negative; the automated CTP “core only” map correctly classified each as >70 ml or ≤70 ml, while the “core + penumbra” map misclassified 4 as >70 ml. There were strong correlations between DWI volume with both summary map-based volumes: “core only” (r = 0.93), and “core + penumbra” (r = 0.77) (both p < 0.0001). Agreement between ASPECTS scores of infarct core on DWI with summary maps was 0.65–0.74 for “core only” map, and 0.61–0.65 for “core + penumbra” (both p < 0.0001). Using DWI-based ASPECTS scores as the standard, the accuracy of the CTP-based maps were 79.1–86.0% for the “core only” map, and 83.7–88.4% for “core + penumbra.” Conclusion: Automated CTP summary maps appear to be relatively accurate in both the detection of acute MCA distribution infarcts, and the discrimination of volumes using a 70 ml threshold.

Twenty-one DAI patients treated at our hospital between July 1997 and December 1999 were evaluated. CBF was measured using Xenon computed tomography. Axial T1-, axial T2-, and sagittal T2-weighted MRI scans were performed using a 0.5 Tesla MR scanner. Each examination was performed within seven days of the onset of symptoms. Patients were divided into two groups according to their Glasgow outcome scale after six months: a good outcome group (n=14, good recovery or moderate disability), and a poor outcome group (n=7, severe disability, vegetative state or death). We compared the inter-group average ages, Glasgow coma scale (GCS) ratings upon admission, and CBF values using the Student t-test. Inter-group differences regarding the presence of lesions on MRI images were assessed using the Mann-Whitney test. The age of the good outcome group was significantly lower than that of the poor outcome group (31.4{+-}15.1 years vs 49.6{+-}24.1 years; p<0.05). The GCS ratings were not significantly different (7.1{+-}2.2 vs 5.9{+-}1.5). The CBF of the good outcome group tended to be higher than that of the poor outcome group, but the difference was not statistically significant (43.2{+-}12.8 ml/100 g/min vs 33.6{+-}7.4 ml/100 g/min). The presence of lesions in the thalamus and brain stem on MRI images was correlated with the outcome of the patients, especially in patients with a lesion in their brain stem (p<0.01). Lesions in the corpus callosum were observed in both groups, and their presence was not correlated with patient outcome. We conclude that DAI patients who are older or whose MRI examinations reveal the presence of a lesion in their brain stem may have difficulty leading an independent daily life and that the prognosis of acute-phase DAI patients cannot be

    BACKGROUND To explore the time-dependent effects of acupuncture on mRNA levels of the apoptotic factors BCL-2 and BAX in a rat cerebral hemorrhage model, slow injection of autologous blood to the caudate nucleus was used to generate the cerebral hemorrhage model. MATERIAL AND METHODS A sham surgery control group, groups with acupuncture applied 3, 9, 24, and 48 hours after model induction, and time-matched model-only control groups were used. In situ hybridization was used to detect BCL-2 and BAX mRNA expression, and semi-quantitative RT-PCR was used to measure the expression. RESULTS The number of BCL-2 and BAX mRNA-positive cells significantly increased during the acute phase of cerebral hemorrhage. BCL-2 mRNA was significantly upregulated in acupuncture groups compared to other groups, whereas BAX mRNA levels in the acupuncture groups were lower in the other groups, except for the sham surgery group. Additionally, earlier acupuncture intervention was associated with a lower ratio of expression between the two genes. Changes in BCL-2 and BAX mRNA expression were consistent with changes in the number of cells positive for BCL-2 and BAX mRNA; however, the change in the expression ratio was consistent with the change in the number of cells positive for BCL-2 mRNA, but opposite to the change in the number of cells positive for BAX mRNA. CONCLUSIONS Acupuncture ameliorated changes in expression of apoptotic factors in the brain induced by acute cerebral hemorrhage and may thus protect the brain, with greater efficacy when the delay before acupuncture was minimized.

    The experiment was performed on 86 cases under intraperitoneal pentobarbital anesthesia. One balloon was placed in the extradural space of right frontal region, and the other balloon was placed in the left extradural space and the intracranial pressure was measured. A needle was stereotaxically inserted into the subcortical area in order to measure the cerebral blood flow. Systemic blood pressure was recorded by inserting a catheter into the femoral artery, and electrocorticogram was also recorded. An expanding intracranial lesion was made by inflating the extradural balloon with physiological saline. The animals were arbitrarily divided into two groups.: 1) light or moderate groups which intracranial pressure before the injection of drug was below 400 mmH2O. 2) severe groups above 400 mmH2O. After the maintenance of the pressure, Solcoseryl was infused intravenously. The investigation was focused to observe whether Solcoseryl reveales any potent effect on cerebral blood flow, intracranial pressure, systemic blood pressure and on electroencephalogram in acute intracranial hypertension. Results 1) Intravenous injection of Solcoseryl had the effect of lowering intracranial pressure in the light or moderate and severe groups. Particularly, dose of 80 mg/kg showed the marked effect, though with a rebound phenomenon in the light or moderate groups. Furthermore, the effect was more marked and lasting by drip infusion of Solcoseryl and also by intravenous injection of Solcoseryl after pretreatment with hydrocortisone, and at this time no rebound phenomenon was recognized. 2) Solcoseryl had the effect of increasing the cerebral blood flow accompained with the lowering of intracranial pressure. 3) Systemic blood pressure was transiently lowered by the injection of Solcoseryl 20 mg/kg or 80 mg/kg and recovered immediately. 4) Solcoseryl had no effect on electroencephalogram in the severe groups. Conclusion On the basis of these results, it is rational to conclude that

    BACKGROUND: The early correct diagnosis of acute cerebral infarction (ACI) is very important for choosing therapeutic regimen. The classification of Oxfordshire community stroke project (OCSP) provides guide for easy and rapid diagnosis and choosing therapeutic regimen in clinical practice. But current operation is not satisfied. Only depending on clinical symptoms and body signs do objective evidences lack. Transcranial Doppler ultrasound (TCD) examination may provide hemodynamical evidences for the correct classification of OCSP to some extent. OBJECTIVE: To compare the results of OCSP classification and TCD examination for treating ACI in patients, and analyze the relationship between them as well as the effect of TCD on the correct classification of OCSP. DESIGN: Controlled observation.SETTING: Department of Internal Medicine, Shenzhen Hospital of Prevention and Treatment for Occupational Disease. PARTICIPANTS: Thirty-eight inpatients with ACI including 21 males and 17 females, aged 50 to 81 years, who received treatment in the Department of Internal Medicine, Shenzhen Hospital of Prevention and Treatment for Occupational Disease within 24 hours after onset from October 2002 to October 2005 were involved. The involved inpatients all confirmed to the diagnostic criteria of ACI formulated in the 4th National Cerebrovas- cular Diseases Conference. All the cases received skull computer tomography (CT) or magnetic resonance imaging (MRI) examinations at 24 hours after onset. Those patients who had no obvious infarct focus in skull CT examination within 24 hours after onset were performed re-examination to verify ACI within 72 hours after onset. Informed consents of examination method were obtained from all the patients. METHODS: According to the classification of OCSP, the patients were assigned into 4 subtypes: lacunar infarction (LACI), total anterior circulation infarction (TACI), part anterior circulation infarction (PACI) and posterior circulation infarction

  15. Regional cerebral blood flow in acute stage ischemic cerebrovascular disease by xenon-133 inhalation and single photon emission computerized tomography

    Kurokawa, Hiroyuki (Akita Univ. (Japan). School of Medicine)

    1989-03-01

    During the period from February 1984 through June 1985, single photon emission computerized tomography (SPECT) with xenon-133 inhalation method has been performed for the measurement of regional cerebral blood flow (rCBF) during the first 48 hours of onset of cerebral infarction (n=71) and transient ischemic attack (n=21). X-ray CT (CT) and carotid arteriography were concurrently performed in all the patients. In repeated studies performed for 15 normal volunteers, rCBF measurement by SPECT was found reproducible. Mean values of rCBF for the right and left cerebral hemispheres were 60.3{plus minus}6.52 and 61.8{plus minus}6.91 ml/100 g/min, respectively. For cerebral infarction, ischemic foci corresponding to clinical symptoms were detected more frequently on SPECT than on CT (93% vs 63%). In all of the evaluable 35 patients with cerebral infarction, rCBF within the first 8 hours of onset was decreased: 31.0 ml/100 g/min for the internal carotid artery (ICA) occlusion and 36.0 ml/100 g/min for the middle cerebral artery (MCA) occlusion. Crossed cerebellar diaschisis was observed in 50% (9/18) for ICA occlusion and 37% (14/38) for MCA occlusion. For transient ischemic attack, there was no significant difference in the detection of ischemic foci between SPECT and CT (38% vs 43%). In detecting small foci especially in the deep regions such as the basal ganglia, SPECT was inferior to CT. Mean rCBF for transient ischemic attack tended to be lower than the normal rCBF (50.7 ml/100 g/min for the right cerebral hemisphere and 50.6 ml/100 g/min for the left cerebral hemisphere). SPECT may aid in predicting prognosis and chosing treatment strategy, as well as in determining cerebral hemodynamics. (N.K.).

    Electroacupuncture at the head acupoints Baihui (GV20) and Shuigou (GV26) improves recovery of neurological function following isch-emic cerebrovascular events, but its mechanism remains incompletely understood. We hypothesized that the action of electroacupuncture at these acupoints is associated with elevated serum levels of transforming growth factor beta 1 (TGF-β1). To test this, we established a rat model of cerebral ischemia by middle cerebral artery occlusion. Electroacupuncture was performed at Baihui and Shuigou with a“disperse-dense”wave at an alternating frequency of 2 and 150 Hz, and at a constant intensity of 3 mA. Each electroacupuncture session lasted 30 minutes and was performed every 12 hours for 3 days. Neurological severity scores were lower in injured rats after acupuncture than in those not subjected to treatment. Furthermore, serum level of TGF-β1 was greater after electroacupuncture than after no treatment. Our results indicate that electroacupuncture at Baihui and Shuigou increases the serum level of TGF-β1 in rats with acute cerebral ischemia/reperfusion injury, and exerts neuroprotective effects.

  19. Adenosine mediates decreased cerebral metabolic rate and increased cerebral blood flow during acute moderate hypoxia in the near-term fetal sheep.

    Blood, Arlin B; Hunter, Christian J; Power, Gordon G

    2003-12-15

    Exposure of the fetal sheep to moderate to severe hypoxic stress results in both increased cortical blood flow and decreased metabolic rate. Using intravenous infusion of 8-cyclopentyl-1,3-dipropylxanthine (DPCPX), a selective adenosine A1 receptor antagonist that is permeable to the blood brain barrier, we examine the role of adenosine A1 receptors in mediating cortical blood flow and metabolic responses to moderate hypoxia. The effects of DPCPX blockade are compared to controls as well as animals receiving intravenous 8-(p-sulfophenyl)-theophylline) (8-SPT), a non-selective adenosine receptor antagonist which has been found to be blood brain barrier impermeable. Laser Doppler flow probes, tissue PO2, and thermocouples were implanted in the cerebral cortices of near-term fetal sheep. Catheters were placed in the brachial artery and sagittal sinus vein for collection of samples for blood gas analysis. Three to seven days later responses to a 30-min period of fetal hypoxemia (arterial PO2 10-12 mmHg) were studied with administration of 8-SPT, DPCPX, or vehicle. Cerebral metabolic rate was determined by calculation of both brain heat production and oxygen consumption. In response to hypoxia, control experiments demonstrated a 42 +/- 7 % decrease in cortical heat production and a 35 +/- 10 % reduction in oxygen consumption. In contrast, DPCPX infusion during hypoxia resulted in no significant change in brain heat production or oxygen consumption, suggesting the adenosine A1 receptor is involved in lowering metabolic rate during hypoxia. The decrease in cerebral metabolic rate was not altered by 8-SPT infusion, suggesting that the response is not mediated by adenosine receptors located outside the blood brain barrier. In response to hypoxia, control experiments demonstrated a 35 +/- 7 % increase in cortical blood flow. DPCPX infusion did not change this increase in cortical blood flow, however 8-SPT infusion attenuated increases in flow, indicating that hypoxic

    Computed tomography (CT) is still the primary imaging modality following acute stroke. To evaluate a prototype of software for the calculation of color-coded whole-brain perfused blood volume (PBV) images from CT angiography (CTA) and nonenhanced CT (NECT) scans, we studied 14 patients with suspected acute ischemia of the anterior cerebral circulation. PBV calculations were performed retrospectively. The detection rate of ischemic changes in the PBV images was compared with NECT. The volume of ischemic changes in PBV was correlated with the infarct volume on follow-up examination taking potential vessel recanalization into account. PBV demonstrated ischemic changes in 12/12 patients with proven infarction and was superior to NECT (8/12) in the detection of early ischemia. Moreover, PBV demonstrated the best correlation coefficient with the follow-up infarct volume (Pearson's R = 0.957; P = 0.003) for patients with proven recanalization of initially occluded cerebral arteries. In summary, PBV appears to be more accurate in the detection of early infarction compared to NECT and mainly visualizes the irreversibly damaged ischemic tissue. (orig.)

    Background. The diagnosis of cerebral malaria is problematic in malaria-endemic areas because encephalopathy in patients with parasitemia may have another cause. Abnormal retinal findings are thought to increase the specificity of the diagnosis, and the level of histidine-rich protein 2 (HRP2) may reflect the parasite biomass. Methods. We examined the retina and measured plasma HRP2 levels in children with acute nontraumatic encephalopathy in Kenya. Logistic regression, with HRP2 level as an independent variable and World Health Organization–defined cerebral malaria and/or retinopathy as the outcome, was used to calculate malaria-attributable fractions (MAFs) and retinopathy-attributable fractions (RAFs). Results. Of 270 children, 140 (52%) had peripheral parasitemia, 80 (30%) had malaria retinopathy, and 164 (61%) had an HRP2 level of >0 U/mL. During 2006–2011, the incidence of HRP2 positivity among admitted children declined by 49 cases per 100 000 per year (a 78% reduction). An HRP2 level of >0 U/mL had a MAF of 93% for cerebral malaria, with a MAF of 97% observed for HRP2 levels of ≥10 U/mL (the level of the best combined sensitivity and specificity). HRP2 levels of >0 U/mL had a RAF of 77% for features of retinopathy combined, with the highest RAFs for macular whitening (99%), peripheral whitening (98%), and hemorrhages (90%). Conclusion. HRP2 has a high attributable fraction for features of malarial retinopathy, supporting its use in the diagnosis of cerebral malaria. HRP2 thresholds improve the specificity of the definition. PMID:24041795

    Objective: To study the effects of mild hypothermia on cerebral oxygen partial pressure, carbon dioxide partial pressure, pH and body temperature (PbrO2, PbrCO2, pHbr and BT) in patients with acute severe head injury.Methods: Thirty-eight patients with acute severe head injury were treated with mild hypothermia, meantime PbrO2, PbrCO2, pHbr and BT were monitored in order to study the changes of PbrO2, PbrCO2, pHbr and BT.Results: In patients with acute head injury, mild hypothermia obviously increased PbrO2, decreased PbrCO2 and CO2 accumulation and acidosis in brain tissue. BT was 1℃-1.5℃ higher than rectal temperature(RT) after injury. The BT and RT were decreased when the patients were treated with mild hypothermia, but at the same time the difference between BT and RT was increased.Conclusions: In patients with acute severe head injury the direct monitoring of PbrO2, PbrCO2, pHbr and BT was safe and reliable, and is helpful in estimating prognosis and mild hypothermia therapy.

  6. Clinical Neuroimaging of cerebral ischemia

    Notice points in clinical imaging of cerebral ischemia are reviewed. When cerebral blood flow is determined in acute stage of cerebral embolism (cerebral blood flow SPECT), it is important to find area of ischemic core and ischemic penumbra. When large cortex area is assigned to ischemic penumbra, thrombolytic therapy is positively adapted, but cautious correspondence is necessary when ischemic core is recognized. DWI is superior in the detection of area equivalent to ischemic core of early stage, but, in imaging of area equivalent to ischemic penumbra, perfusion image or distribution image of cerebral blood volume (CBV) by MRI need to be combined. Luxury perfusion detected by cerebral blood flow SPECT in the cases of acute cerebral embolism suggests vascular recanalization, but a comparison with CT/MRI and continuous assessment of cerebral circulation dynamics were necessary in order to predict brain tissue disease (metabolic abnormality). In hemodynamic cerebral ischemia, it is important to find stage 2 equivalent to misery perfusion by quantification of cerebral blood flow SPECT. Degree of diaschisis can indicate seriousness of brain dysfunction for lacuna infarct. Because cerebral circulation reserve ability (perfusion pressure) is normal in all areas of the low cerebral blood flow by diaschisis mechanism, their areas are easily distinguished from those of hemodynamic cerebral ischemia.

    Objective: To observe the therapeutic effect of electroacupuncture (EA) on plasma angiotensin (Ang*.Ⅱ), aldosterone (ALD) and atrial natriuretic polypeptide (ANP) contents in experimental cerebral infarction rabbits for analyzing the underlying mechanism of acupuncture in ameliorating blood supply of the brain tissue. Methods: A total of 80 rabbits were randomized into control (n=8), pseudo-operation (n=24), model (n=24) and EA (n=24) groups. Cerebral infarction model was established by infusion of self-thrombus into the carotid artery. EA (1 mA, 2 Hz) was applied to "Baihui"(百会GV 20) and "Shuigou"(水沟GV 26) for 30 min, once every 12 hours. Plasma Ang-II, ALD and ANP contents were detected with radioimmunoassay method. In the later 3 groups, blood samples were taken at 6 h, 24 h and 48 h after cerebral ischemia. Results: Compared with control and pseudo-operation groups, Ang-II and ALD contents of model group at 6 h, 24 h and 48 h after cerebral ischemia increased significantly while plasma ANP of the 3 time-courses of model group decreased considerably (P<0.01). In comparison with model group, results showed that Ang-II and ALD contents of EA group decreased significantly whereas ANP level of EA group increased strikingly (P<0.01). Conclusion: Electroacupuncture has the effects of raising plasma ANP level and lowering plasma Ang-II and ALD in cerebral infarction rabbits.

    Full Text Available PURPOSE: The aim of this study was to assess the effect of acute bilateral jugular vein compression on: (1 pial artery pulsation (cc-TQ; (2 cerebral blood flow velocity (CBFV; (3 peripheral blood pressure; and (4 possible relations between mentioned parameters. METHODS: Experiments were performed on a group of 32 healthy 19-30 years old male subjects. cc-TQ and the subarachnoid width (sas-TQ were measured using near-infrared transillumination/backscattering sounding (NIR-T/BSS, CBFV in the left anterior cerebral artery using transcranial Doppler, blood pressure was measured using Finapres, while end-tidal CO(2 was measured using medical gas analyser. Bilateral jugular vein compression was achieved with the use of a sphygmomanometer held on the neck of the participant and pumped at the pressure of 40 mmHg, and was performed in the bend-over (BOPT and swayed to the back (initial position. RESULTS: In the first group (n = 10 during BOPT, sas-TQ and pulse pressure (PP decreased (-17.6% and -17.9%, respectively and CBFV increased (+35.0%, while cc-TQ did not change (+1.91%. In the second group, in the initial position (n = 22 cc-TQ and CBFV increased (106.6% and 20.1%, respectively, while sas-TQ and PP decreases were not statistically significant (-15.5% and -9.0%, respectively. End-tidal CO(2 remained stable during BOPT and venous compression in both groups. Significant interdependence between changes in cc-TQ and PP after bilateral jugular vein compression in the initial position was found (r = -0.74. CONCLUSIONS: Acute bilateral jugular venous insufficiency leads to hyperkinetic cerebral circulation characterised by augmented pial artery pulsation and CBFV and direct transmission of PP into the brain microcirculation. The Windkessel effect with impaired jugular outflow and more likely increased intracranial pressure is described. This study clarifies the potential mechanism linking jugular outflow insufficiency with arterial small vessel cerebral

    MR-derived cerebral metabolic rate of oxygen utilization (CMRO{sub 2}) has been suggested to be analogous to PET-derived CMRO{sub 2} and therefore may be used for detection of viable tissue at risk for infarction. The purpose of this study was to evaluate MR-derived CMRO{sub 2} mapping in acute ischemic stroke in relation to established diffusion- and perfusion-weighted imaging. In 23 patients (mean age 63 ± 18.7 years, 11 women) with imaging findings for acute ischemic stroke, relative oxygen extraction fraction was calculated from quantitative transverse relaxation times (T2, T2*) and relative cerebral blood volume using a quantitative blood oxygenation level dependent (BOLD) approach in order to detect a local increase of deoxyhemoglobin. Relative CMRO{sub 2} (rCMRO{sub 2}) maps were calculated by multiplying relative oxygen extraction fraction (rOEF) by cerebral blood flow, derived from PWI. After co-registration, rCMRO{sub 2} maps were evaluated in comparison with apparent diffusion coefficient (ADC) and time-to-peak (TTP) maps. Mean rCMRO{sub 2} values in areas with diffusion-restriction or TTP/ADC mismatch were compared with rCMRO{sub 2} values in the contralateral tissue. In tissue with diffusion restriction, mean rCMRO{sub 2} values were significantly decreased compared to perfusion-impaired (17.9 [95 % confidence interval 10.3, 25.0] vs. 58.1 [95 % confidence interval 50.1, 70.3]; P < 0.001) and tissue in the contralateral hemisphere (68.2 [95 % confidence interval 61.4, 75.0]; P < 0.001). rCMRO{sub 2} in perfusion-impaired tissue showed no significant change compared to tissue in the contralateral hemisphere (58.1 [95 % confidence interval 50.1, 70.3] vs. 66.7 [95 % confidence interval 53.4, 73.4]; P = 0.34). MR-derived CMRO{sub 2} was decreased within diffusion-restricted tissue and stable within perfusion-impaired tissue, suggesting that this technique may be adequate to reveal different pathophysiological stages in acute stroke.

    Full Text Available Context:Eye-movement training (EMT can induce altered brain activation and change the functionality of saccades with changes of the brain in general. Objective:To determine if EMT would result in changes in qEEG and NIH Stroke Scales (NIHSS in patients suffering from acute middle cerebral artery (MCA infarction. Our hypothesis is that there would be positive changes in qEEG and NIHSS after EMT in patients suffering from acute MCA ischemic stroke.Design:Double blind randomized controlled trial.Setting and Participants:34 subjects with acute MCA ischemic stroke at university affiliated hospital intensive care unit.Interventions:Subjects were randomized into a control group treated only with aspirin (125 mg/day and a treatment group treated with aspirin (125 mg/day and a subject specific EMT. Main Outcome measures: Delta-Alpha Ratio, Power Ratio Index and the Brain Symmetry Index calculated by quantitative electroencephalograms, and NIHSS. Results:There was strong statistical and substantive significant improvement in all outcome measures for the group of stroke patients undergoing EMT. Such improvement was not observed for the control group and there were no adverse effects.Conclusions:The addition of EMT to a MCA ischemic stroke treatment paradigm has demonstrated statistically significant changes in outcome measures and is a low cost, safe and effective complement to standard treatment.

The anterior cingulate gyrus was activated during hypoglycemia in a load-dependent manner. Areas on the frontal convexity were differentially activated in response to the cognitive load...... during hypoglycemia. Our findings suggest that hypoglycemia induces changes in sensory processing in a cognition-independent manner, whereas activation of areas of higher order functions is influenced by cognitive load as well as hypoglycemia.......Blurred vision and cognitive difficulties are prominent symptoms during acute insulin-induced hypoglycemia. Our hypothesis was that changes in cerebral activity reflect these symptoms. Positron emission tomography (PET) with oxygen-15-labelled water was used to measure relative changes in regional...

  1. Acute liver failure in rats activates glutamine-glutamate cycle but declines antioxidant enzymes to induce oxidative stress in cerebral cortex and cerebellum.

    Santosh Singh

    Full Text Available BACKGROUND AND PURPOSE: Liver dysfunction led hyperammonemia (HA causes a nervous system disorder; hepatic encephalopathy (HE. In the brain, ammonia induced glutamate-excitotoxicity and oxidative stress are considered to play important roles in the pathogenesis of HE. The brain ammonia metabolism and antioxidant enzymes constitute the main components of this mechanism; however, need to be defined in a suitable animal model. This study was aimed to examine this aspect in the rats with acute liver failure (ALF. METHODS: ALF in the rats was induced by intraperitoneal administration of 300 mg thioacetamide/Kg. b.w up to 2 days. Glutamine synthetase (GS and glutaminase (GA, the two brain ammonia metabolizing enzymes vis a vis ammonia and glutamate levels and profiles of all the antioxidant enzymes vis a vis oxidative stress markers were measured in the cerebral cortex and cerebellum of the control and the ALF rats. RESULTS: The ALF rats showed significantly increased levels of ammonia in the blood (HA but little changes in the cortex and cerebellum. This was consistent with the activation of the GS-GA cycle and static levels of glutamate in these brain regions. However, significantly increased levels of lipid peroxidation and protein carbonyl contents were consistent with the reduced levels of all the antioxidant enzymes in both the brain regions of these ALF rats. CONCLUSION: ALF activates the GS-GA cycle to metabolize excess ammonia and thereby, maintains static levels of ammonia and glutamate in the cerebral cortex and cerebellum. Moreover, ALF induces oxidative stress by reducing the levels of all the antioxidant enzymes which is likely to play important role, independent of glutamate levels, in the pathogenesis of acute HE.

    Since the inflammatory response and oxidative stress are involved in the stroke cascade, we evaluated here the effects of Phycocyanobilin (PCB, the C-Phycocyanin linked tetrapyrrole) on PC12 cell survival, the gene expression and the oxidative status of hypoperfused rat brain. After the permanent bilateral common carotid arteries occlusion (BCCAo), the animals were treated with saline or PCB, taking samples 24 h post-surgery. Global gene expression was analyzed with GeneChip Rat Gene ST 1.1 from Affymetrix; the expression of particular genes was assessed by the Fast SYBR Green RT-PCR Master Mix and Bioplex methods; and redox markers (MDA, PP, CAT, SOD) were evaluated spectrophotometrically. The PCB treatment prevented the H{sub 2}O{sub 2} and glutamate induced PC12 cell injury assessed by the MTT assay, and modulated 190 genes (93 up- and 97 down-regulated) associated to several immunological and inflammatory processes in BCCAo rats. Furthermore, PCB positively modulated 19 genes mostly related to a detrimental pro-inflammatory environment and counteracted the oxidative imbalance in the treated BCCAo animals. Our results support the view of an effective influence of PCB on major inflammatory mediators in acute cerebral hypoperfusion. These results suggest that PCB has a potential to be a treatment for ischemic stroke for which further studies are needed. - Highlights: • Phycocyanobilin (PCB) prevents H{sub 2}O{sub 2} and glutamate induced PC12 cell viability loss. • Anterior cortex and striatum are highly vulnerable to cerebral hypoperfusion (CH). • PCB modulates 190 genes associated to inflammation in acute CH. • PCB regulates 19 genes mostly related to a detrimental pro-inflammatory environment. • PCB restores redox and immune balances showing promise as potential stroke therapy.

    The aim of this study was to determine the acute effects of the 'Ecstasy' analogue MDE (3,4-methylene dioxyethamphetamine) on cerebral glucose metabolism (rMRGlu) of healthy volunteers and to correlate neurometabolism with acute psychopathology. In a radomized double-blind trial, 15 healthy volunteers without a history of drug abuse were examined with fluorine-18-deoxyglucose ({sup 18}FDG) positron emission tomography (PET) 110-120 min after oral administration of 2 mg/kg MDE (n=7) or placebo (n=8). Two minutes prior to radiotracer injection, constant cognitive stimulation was started and maintained for 32 min using a word repetition paradigm to ensure constant and comparable mental conditions during cerebral glucose uptake. Individual brain anatomy was represented using T1-weighted 3D flash magnetic resonance imaging (MRI), followed by manual regionalization into 108 regions of interest and PET/MRI overlay. After absolute quantification of rMR-Glu and normalization to global metabolism, normalized rMRGlu under MDE was compared to placebo using the Mann-Whitney U-test. Acute psychopathology was assessed using the Positive and Negative Syndrome Scale (PANSS) and rMRGlu was correlated to PANSS scores according to Spearman. MDE subjects showed significantly decreased rMRGlu in the bilateral frontal cortex: left frontal posterior (-7.1%, P<0.05) and right prefrontal superior (-4.6%, P<0.05). On the other hand, rMR-Glu was significantly increased in the bilateral cerebellum (right: +10.1%, P<0.05; left: +7.6%, P<0.05) and in the right putamen (+6.2%, P<0.05). There were positive correlations between rMRGlu in the middle right cingulate and grandiosity (r=0.87; P<0.05), both the right amygadala (r=0.90, P<0.01) and the left posterior cingulate (r=0.90, P<0.01) to difficulties in abstract thinking, and the right frontal inferior (r=0.85, P<0.05), right anterior cingulate (r=0.93, P<0.01), and left anterior cingulate (r=0.85, P<0.05) to attentional deficits.

    2014-11-01

    Full Text Available We aimed at comparing the sensitivity of magnetic resonance (MR susceptibility-weighted imaging (SWI with computed tomography angiography (CTA in the detection of middle cerebral artery (MCA thrombus in acute stroke. Seventy-nine patients with acute MCA stroke was selected using our search engine software; only the ones showing restricted diffusion in the MCA territory on diffusion-weighted images were included. We finally selected 35 patients who had done both MRI (including SWI and CTA. Twenty random subjects with completely normal MRI (including SWI exam were selected as control. Two neuroradiologists (blinded to the presence or absence of stroke reviewed the SW images and then compared the findings with CT angiogram (in patients with stroke. The number of MCA segments showing thrombus in each patient was tabulated to estimate the thrombus burden. Thrombus was detected on SWI in one or more MCA segments in 30 out of 35 patients, on the first review. Of the 30, SWI showed thrombus in more than one MCA segments in 7 patients. CTA depicted branch occlusion in 31 cases. Thrombus was seen on both SWI and CTA in 28 patients. Thrombus was noted in two patients on SWI only, with no corresponding abnormality seen on CTA. Two patients with acute MCA showed no vascular occlusion or thrombus on either CTA or SWI. Only two case of false-positive thrombus was reported in normal control subjects. Susceptibility-weighted images had sensitivity and specificity of 86% and 90% respectively, with positive predictive value 94%. Sensitivity was 86% for SWI, compared with 89% for CTA, and this difference was statistically insignificant (P>0.05. Of all the positive cases on CTA (31 corresponding thrombus was seen on SWI in 90% of subjects (28 of 31. Susceptibility-weighted imaging has high sensitivity for detection of thrombus in acute MCA stroke. Moreover, SWI is a powerful technique for estimation of thrombus burden, which can be challenging on CTA.

    Cerebral malaria is the most severe complication of Plasmodium falciparum infection, and a leading cause of death in children under the age of five in malaria-endemic areas. We report high therapeutic efficacy of a novel formulation of liposome-encapsulated water-soluble glucocorticoid prodrugs, and in particular β-methasone hemisuccinate (BMS), for treatment of experimental cerebral malaria (ECM), using the murine P. berghei ANKA model. BMS is a novel derivative of the potent steroid β-methasone, and was specially synthesized to enable remote loading into nano-sterically stabilized liposomes (nSSL), to form nSSL-BMS. The novel nano-drug, composed of nSSL remote loaded with BMS, dramatically improves drug efficacy and abolishes the high toxicity seen upon administration of free BMS. nSSL-BMS reduces ECM rates in a dose-dependent manner and creates a survival time-window, enabling administration of an antiplasmodial drug, such as artemisone. Administration of artemisone after treatment with the nSSL-BMS results in complete cure. Treatment with BMS leads to lower levels of cerebral inflammation, demonstrated by changes in cytokines, chemokines, and cell markers, as well as diminished hemorrhage and edema, correlating with reduced clinical score. Administration of the liposomal formulation results in accumulation of BMS in the brains of sick mice but not of healthy mice. This steroidal nano-drug effectively eliminates the adverse effects of the cerebral syndrome even when the treatment is started at late stages of disease, in which disruption of the blood-brain barrier has occurred and mice show clear signs of neurological impairment. Overall, sequential treatment with nSSL-BMS and artemisone may be an efficacious and well-tolerated therapy for prevention of CM, elimination of parasites, and prevention of long-term cognitive damage.

    Objective To study the clinical significance of early changes in cerebral oxygen and glucose metabolism in patients with cerebral hemorrhage and with Glasgow coma score (GCS) of 5-8 caused by acute hypertension in order to find relationship between those changes and prognosis.Methods From January 1,2011 to June 30,2012,a cohort of 43 patients with cerebral hemorrhage caused by acute hypertension were enrolled for retrospective study.Radial artery and internal jugular vein were separately cannulated retrogradely for collecting blood for blood gas analysis and blood glucose tests carried out 24 hours after the onset of the cerebral hemorrhage and then every 6-8 hours and as any major changes in physical signs of patients occurred.And this monitoring kept for consecutive 3 days.The data of these laboratory findings were analyzed and calculated to determine internal jugular vein oxygen saturation (SjVO2),cerebral oxygen utilization rate (CEO2),cerebral arterio-venous oxygen difference (AVDO2),arterio-venous blood glucose difference (V-Aglu),arterio-venous lactic acid difference (V-Alac) and absolute value of carbon dioxide pressure difference between jugular vein and artery (V-APCO2).All patients met the diagnostic criteria of hypertensive cerebral hemorrhage revised by the 4th National Academic Conference on cerebrovascular disease in 1995 requiring diagnosis confirmed by brain CT,admitted within 24 hours of onset,Glasgow coma score (GCS) 5-8 and a history of hypertension.Exclusion criteria were:cerebral hemorrhage caused by traumatic intracranial hematoma,spontaneous subarachnoid hemorrhage,arteriovenous malformation and Moyamoya disease,intracranial tumor apoplexy,cerebral bleeding derived from the disturbance of blood coagulation system,and cerebral hemorrhagic infarction.According to the short-term prognosis,the patients were divided into the death group and the survival group.Then the differences in biomarkers mentioned above between two groups were compared to

    The purpose of this study is to compare the variability of PCT results obtained by automatic selection of the arterial input function (AIF), venous output function (VOF) and symmetry axis versus manual selection. Imaging data from 30 PCT studies obtained as part of standard clinical stroke care at our institution in patients with suspected acute hemispheric ischemic stroke were retrospectively reviewed. Two observers performed the post-processing of 30 CTP datasets. Each observer processed the data twice, the first time employing manual selection of AIF, VOF and symmetry axis, and a second time using automated selection of these same parameters, with the user being allowed to adjust them whenever deemed appropriate. The volumes of infarct core and of total perfusion defect were recorded. The cerebral blood volume (CBV), cerebral blood flow (CBF), mean transit time (MTT) and blood-brain barrier permeability (BBBP) values in standardized regions of interest were recorded. Interobserver variability was quantified using the Bland and Altman's approach. Automated post-processing yielded lower coefficients of variation for the volume of the infarct core and the volume of the total perfusion defect (15.7% and 5.8%, respectively) compared to manual post-processing (31.0% and 12.2%, respectively). Automated post-processing yielded lower coefficients of variation for PCT values (11.3% for CBV, 9.7% for CBF, and 9.5% for MTT) compared to manual post-processing (23.7% for CBV, 32.8% for CBF, and 16.7% for MTT). Automated post-processing of PCT data improves interobserver agreement in measurements of CBV, CBF and MTT, as well as volume of infarct core and penumbra. (orig.)

    Full Text Available The capability of CT perfusion (CTP Alberta Stroke Program Early CT Score (ASPECTS to predict outcome and identify ischemia severity in acute ischemic stroke (AIS patients is still questioned.62 patients with AIS were imaged within 8 hours of symptom onset by non-contrast CT, CT angiography and CTP scans at admission and 24 hours. CTP ASPECTS was calculated on the affected hemisphere using cerebral blood flow (CBF, cerebral blood volume (CBV and mean transit time (MTT maps by subtracting 1 point for any abnormalities visually detected or measured within multiple cortical circular regions of interest according to previously established thresholds. MTT-CBV ASPECTS was considered as CTP ASPECTS mismatch. Hemorrhagic transformation (HT, recanalization status and reperfusion grade at 24 hours, final infarct volume at 7 days and modified Rankin scale (mRS at 3 months after onset were recorded.Semi-quantitative and quantitative CTP ASPECTS were highly correlated (p<0.00001. CBF, CBV and MTT ASPECTS were higher in patients with no HT and mRS ≤ 2 and inversely associated with final infarct volume and mRS (p values: from p<0.05 to p<0.00001. CTP ASPECTS mismatch was slightly associated with radiological and clinical outcomes (p values: from p<0.05 to p<0.02 only if evaluated quantitatively. A CBV ASPECTS of 9 was the optimal semi-quantitative value for predicting outcome.Our findings suggest that visual inspection of CTP ASPECTS recognizes infarct and ischemic absolute values. Semi-quantitative CBV ASPECTS, but not CTP ASPECTS mismatch, represents a strong prognostic indicator, implying that core extent is the main determinant of outcome, irrespective of penumbra size.

    Objective: To investigate the influence of Tongxinluo capsule (TXL, 通心络胶囊) on regional cerebral blood flow (rCBF) with 99mTc-ECD single photon emission computed tomography ( SPECT) brain perfusion imaging, and to observe the therapeutic effects of TXL on acute small cerebral infarction (ASCI).Methods: Thirty-four patients with ASCI were enrolled and randomly divided into two groups: the control group ( n = 17) was treated with the conventional treatment, i.e. 1.0g of Citicoline added into 300 mi normal saline for intravenous dripping daily for 2 weeks and 0.8 g of Piracetam taken three times a day orally for 4 weeks, and the treatment group ( n = 17)was treated additionally with 4 TXL capsules three times a day for 4 weeks besides the conventional treatment. The 99mTc-ECD SPECT brain perfusion imaging was performed before and after treatment to observe the change of rCBF, and the neurological deficit was evaluated by Edinburgh-Scandinavia stroke scale (SSS) scores and Barthel index (BI) at the same time. Results: After treatment, the rCBF in the treatment group was significantly improved ( P<0.01), while that in the control group remained unchanged, with the comparison of the rCBF in the two groups after treatment showing significant difference (P<0.01). In addition, the SSS score was significantly lower and BI significantly higher in the treatment group than those in the control group respectively after treatment. Conclusion: TXL could effectively improve rCBF and lessen the neurological deficit symptoms in patients with ASCI.

    2017-01-01

    Background: Pioneer studies demonstrate the impact of extreme sport load on the human brain, leading to threatening conditions for athlete's health such as cerebral edema. The investigation of brain water diffusivity, allowing the measurement of the intercellular water and the assessment of cerebral edema, can give a great contribution to the investigation of the effects of extreme sports on the brain. We therefore assessed the effect of supra-physiological effort (extreme distance and elevation changes) in mountain ultra-marathons (MUMs) athletes combining for the first time brain magnetic resonance imaging (MRI) and blood parameters. Methods:This longitudinal study included 19 volunteers (44.2 ± 9.5 years) finishing a MUM (330 km, elevation + 24000 m). Quantitative measurements of brain diffusion-weighted images (DWI) were performed at 3 time-points: Before the race, upon arrival and after 48 h. Multiple blood biomarkers were simultaneously investigated. Data analyses included brain apparent diffusion coefficient (ADC) and physiological data comparisons between three time-points. Results:The whole brain ADC significantly increased from baseline to arrival (p = 0.005) and then significantly decreased at recovery (p = 0.005) to lower values than at baseline (p = 0.005). While sodium, potassium, calcium, and chloride as well as hematocrit (HCT) changed over time, the serum osmolality remained constant. Significant correlations were found between whole brain ADC changes and osmolality (p = 0.01), cholesterol (p = 0.009), c-reactive protein (p = 0.04), sodium (p = 0.01), and chloride (p = 0.002) plasma level variations. Conclusions:These results suggest the relative increase of the inter-cellular volume upon arrival, and subsequently its reduction to lower values than at baseline, indicating that even after 48 h the brain has not fully recovered to its equilibrium state. Even though serum electrolytes may only indirectly indicate modifications at the brain level due

    2016-03-01

    Advancements in molecular biology have led to a greater understanding of the individual proteins responsible for generating cerebral edema. In large part, the study of cerebral edema is the study of maladaptive ion transport. Following acute CNS injury, cells of the neurovascular unit, particularly brain endothelial cells and astrocytes, undergo a program of pre- and post-transcriptional changes in the activity of ion channels and transporters. These changes can result in maladaptive ion transport and the generation of abnormal osmotic forces that, ultimately, manifest as cerebral edema. This review discusses past models and current knowledge regarding the molecular and cellular pathophysiology of cerebral edema.

    2000-07-01

    The magnetic resonance (MR) assessment of changes in cerebral white matter in children with acute lymphoblastic leukemia (ALL) after the application of a new treatment. A prospective study was carried out in 50 consecutive children with ALL who had undergone MR imaging during the first 6 months after diagnosis. ALL was classified as standard risk (SR), high risk (HR) or very high risk (VHR) on the basis of conventional criteria. The major difference in the new protocol consisted in a phase of intensification in which different drugs are combined with dexamethasone in cases of HR ALL, together with the exclusion of cranial irradiation in a subgroup of HR patients. ALL the HR and VHR children with changes in white matter, as well as some of those in the SR group, underwent follow-up MR imaging. Thirty-two patients were classified as SR, 15 as HR and 3 as VHR. Changes were observed in 8% of cases (3 patients in the SR group and 1 in the HR group); all were neurologically asymptomatic. The lesions were hyperintense in protein density (PD) and T2-weighted images, with a frontal and occipital periventricular distribution in two cases and occipital in the other two. Serial follow-up images showed a reduction in the lesion in two cases and its persistence in one. The fourth patients died before follow-up images were achieved. There were no new changes in any of the patients. None of the children undergoing cranial irradiation (4 in the HR group and 2 in the VHR group) presented changes in white matter. The incidence of asymptomatic changes in white matter following central nervous system prophylaxis in children with ALL is lower than expected. The different chemoprophylactic protocol during the intensification phase probably protects against the development of these changes. Chemotherapy plays a predominant role in this type of iatrogenesis. (Author) 15 refs.

    Objective:To explore the clinical efficacy of the principle of activating blood circulation to break stasis (ABCBS) and its influence on platelet membranous protein particle (GMP-140) and D2 dimer (Ddimer) before and after treatment. Methods: Eighty-eight patients with blood stasis syndrome (BSS) of acute cerebral infarction (ACI) were randomly divided into two groups, both of which were treated with conventional treatment, i.e. with western medicine (WM), with Salvia injection added through intravenously dripping.One of the two groups was used as the control and the other group as the treated group who had ABCBS herbs orally taken in addition. The duration of treatment course for both groups was 3 weeks. Results: There were changes in both groups over clinical symptoms, nerve function deficit scoring and GMP-140, D-dimer, but the treated group showed significantly better than that of the control group, (P<0.05). Conclusion: ABCBS principle could serve as an important auxiliary treating method for BSS of ACI, as it can effectively alter the blood of ACI patients which was viscous, condense, coagulant and aggregating.

  11. Neuroprotection of hyperbaric oxygen therapy in sub-acute traumatic brain injury:not by immediately improving cerebral oxygen saturation and oxygen partial pressure

    Bao-chun Zhou; Li-jun Liu; Bing Liu

    2016-01-01

    Although hyperbaric oxygen (HBO) therapy can promote the recovery of neural function in patients who have suffered traumatic brain injury (TBI), the underlying mechanism is unclear. We hypothesized that hyperbaric oxygen treatment plays a neuroprotective role in TBI by increasing regional transcranial oxygen saturation (rSO2) and oxygen partial pressure (PaO2). To test this idea, we compared two groups:a control group with 20 healthy people and a treatment group with 40 TBI patients. The 40 patients were given 100% oxygen of HBO for 90 minutes. Changes in rSO2 were measured. The controls were also examined for rSO2 and PaO2, but received no treatment. rSO2 levels in the patients did not differ signiifcantly after treatment, but levels before and after treatment were signiifcantly lower than those in the control group. PaO2 levels were signiifcantly decreased after the 30-minute HBO treatment. Our ifndings suggest that there is a disorder of oxygen metabolism in patients with sub-acute TBI. HBO does not immediately affect cerebral oxygen metabolism, and the underlying mechanism still needs to be studied in depth.

    2015-12-01

    Full Text Available It was reported that cilostazol (CLZ suppressed disruption of the microvasculature in ischemic areas. In this study, we have designed novel injection formulations containing CLZ nanoparticles using 0.5% methylcellulose, 0.2% docusate sodium salt, and mill methods (CLZnano dispersion; particle size 81 ± 59 nm, mean ± S.D., and investigated their toxicity and usefulness in a cerebral ischemia/reperfusion-induced injury model (MCAO/reperfusion mice. The pharmacokinetics of injections of CLZnano dispersions is similar to that of CLZ solutions prepared with 2-hydroxypropyl-β-cyclodextrin, and no changes in the rate of hemolysis of rabbit red blood cells, a model of cell injury, were observed with CLZnano dispersions. In addition, the intravenous injection of 0.6 mg/kg CLZnano dispersions does not affect the blood pressure and blood flow, and the 0.6 mg/kg CLZnano dispersions ameliorate neurological deficits and ischemic stroke in MCAO/reperfusion mice. It is possible that the CLZnano dispersions will provide effective therapy for ischemic stroke patients, and that injection preparations of lipophilic drugs containing drug nanoparticles expand their therapeutic usage.

    We have recently identified T cells as important mediators of ischemic brain damage, but the contribution of the different T-cell subsets is unclear. Forkhead box P3 (FoxP3)-positive regulatory T cells (Tregs) are generally regarded as prototypic anti-inflammatory cells that maintain immune tolerance and counteract tissue damage in a variety of immune-mediated disorders. In the present study, we examined the role of Tregs after experimental brain ischemia/reperfusion injury. Selective depletion of Tregs in the DEREG mouse model dramatically reduced infarct size and improved neurologic function 24 hours after stroke and this protective effect was preserved at later stages of infarct development. The specificity of this detrimental Treg effect was confirmed by adoptive transfer experiments in wild-type mice and in Rag1(-/-) mice lacking lymphocytes. Mechanistically, Tregs induced microvascular dysfunction in vivo by increased interaction with the ischemic brain endothelium via the LFA-1/ICAM-1 pathway and platelets and these findings were confirmed in vitro. Ablation of Tregs reduced microvascular thrombus formation and improved cerebral reperfusion on stroke, as revealed by ultra-high-field magnetic resonance imaging at 17.6 Tesla. In contrast, established immunoregulatory characteristics of Tregs had no functional relevance. We define herein a novel and unexpected role of Tregs in a primary nonimmunologic disease state.

    Methylphenidate (MPH) is the most commonly prescribed treatment for attention-deficit/hyperactivity disorder (ADHD). The therapeutic mechanisms of MPH are not, however, fully understood. We studied the effects of MPH on brain activity in male children and adolescents with ADHD, using the blood flow radiotracer technetium-99m ethyl cysteinate dimer ({sup 99m}Tc-ECD) and single-photon emission tomography (SPET). The study was randomized, double blind, and placebo controlled (MPH group, n=19; placebo group, n=17), Radiotracer was administered during the performance of the Continuous Performance Test and before and after 4 days of MPH treatment. Statistical parametric mapping (SPM99) analysis showed a significant reduction in regional cerebral blood flow in the left parietal region in the MPH group compared with the placebo group (P<0.05, corrected for multiple comparisons). Our findings suggest that the posterior attentional system, which includes the parietal cortex, may have a role in the mediation of the therapeutic effects of MPH in ADHD. (orig.)

    Objective To investigate the correlation between plasma homocysteine(Hcy) level, hypertension and cerebral microb-leeds(CMBs) in patients with acute cerebral infarction. Methods The clinical and imaging data of 74 patients with acute cerebral infarction who had been admitted in this hospital from January 2011 to January 2012 were analyzed retrospectively. According to the existence of cere-bral microbleeds, the patients were divided into two groups, namely the CMB group and the non-CMB group. Blood pressure, blood lipids, blood glucose, and plasma homocysteine were recorded in the two groups of patients, and the risk factors for cerebral microbleeds in acute cerebral infarction were explored. Results A total of 74 patients with acute cerebral infarction were enrolled, 23 of them were females and 51 were males (mean age 66. 22 ± 8. 96 years). Multivariate logistic regression analysis showed that cerebral microbleeds was associated closely with hypertension(OR=4. 67,95% CI:1. 2~17. 65,P=0. 02), but plasma Hcy level was not related to CMBs(OR=1. 01,95%CI:0. 97~1. 06,P=0. 38). Conclusion The level of elevated plasma Hcy in patients with acute cerebral infarction is unrelated to CMBs. Hypertension is significantly associated with CMBs, which might be the independent risk factor for CMBs.%目的:探讨急性脑梗死患者血浆同型半胱氨酸( Hcy)水平、高血压与脑微出血( CMB)的关系。方法选择铜陵市人民医院神经内科2011年1月至2012年1月收治的急性脑梗死患者74例,对其临床及影像学资料进行回顾性分析。根据是否存在CMB分为CMB组和无CMB组。记录两组患者血压、血脂、血糖、血浆Hcy水平等情况,并探讨CMB的危险因素。结果74例急性脑梗死患者中,男性51例,女性23例,平均(66.22±8.96)岁。 logistic回归分析显示,CMB的发生与高血压密切相关(OR=4.67,95% CI ∶1.23~17.65,P=0.02),与血浆Hcy水平无明显相关(OR=1.01,95% CI ∶0.97~1.06,P

    The fungi of the order Mucorales cause mucormycosis, which usually presents as an invasive fungal disease with rapid angioinvasion in immunocompromised patients. Rhinocerebral is the most common presentation. The lipid formulations of amphotericin B are used as primary treatment in invasive mucormycosis; the combined use of posaconazole could allow a reduction in the dose of amphotericin B improving tolerance and adherence to treatment. Caspofungin and amphotericin B association has been shown to be synergistic in vitro and effective in murine models. We present the case of a preschool patient that during the debut of acute lymphoblastic leukemia developed a rhinocerebral mucormycosis successfully responding to antifungal treatment with the combination of liposomal amphotericin and caspofungin.

    Full Text Available Objective: To analyze the serum levels of miR-126, miR-146a and its relationship with infarction area, severity of disease and inflammatory reaction degree in patients with acute cerebral infarction (ACI. Methods: A total of 75 cases with ACI treated in our hospital from April 2014 to October 2015 and 80 healthy cases were respectively selected as ACI group and control group for retrospective study. Patients' clinical data were collected, and the serum levels of miR-126, miR-146a, tumor necrosis factor-a (TNF-a, interleukin-1b (IL-1b and IL-6 were detected. Results: Serum contents of miR-126 (0.286 ± 0.078 vs. 1.000 ± 0.169 and miR-146a (0.337 ± 0.084 vs. 1.000 ± 0.158 in patients of ACI group were significantly lower than those of control group. Contents of IL-1b [(68.4 ± 10.3 vs. (22.7 ± 5.8 ng/L], TNFa [(126.9 ± 22.4 vs. (49.6 ± 8.4 ng/L] and IL-6 [(89.3 ± 14.7 vs. (34.8 ± 5.9 ng/L] were obviously higher than those of control group. The bigger the infarction area was, the more severer the degree of nerve defect could be. The lower the serum levels of miR-126, miR-146a were, the higher the levels of TNF-a, IL-1b, IL-6 could be. Levels of miR-126 and miR-146a were negative correlation with levels of TNF-a, IL-1b and IL-6. Conclusions: An abnormal decrease in serum levels of miR-126 and miR-146a in patients with ACI was closely related to the severity of disease. Through regulating the generation of inflammatory factors TNF-a, IL-1b and IL-6, miR-126 and miR-146a may get involved in the changes of cerebral infarction condition.

  7. Neuroimmunomodulatory effects of transcranial laser therapy combined with intravenous tPA administration for acute cerebral ischemic injury

    Philip V. Peplow

    2015-01-01

    At present, the only FDA approved treatment for ischemic strokes is intravenous administration of tissue plasminogen activator within 4.5 hours of stroke onset. Owing to this brief window only a small percentage of patients receive tissue plasminogen activator. Transcranial laser therapy has been shown to be effective in animal models of acute ischemic stroke, resulting in signiifcant improvement in neurological score and function. NEST-1 and NEST-2 clinical trials in human patients have demonstrated the safety and positive trends in efifcacy of transcranial laser therapy for the treatment of ischemic stroke when initiated close to the time of stroke onset. Combining intravenous tissue plasminogen activator treatment with transcranial laser therapy may provide better functional outcomes. Statins given within 4 weeks of stroke onset improve stroke out-comes at 90 days compared to patients not given statins, and giving statins following transcranial laser therapy may provide an effective treatment for patients not able to be given tissue plasmin-ogen activator due to time constraints.

    1992-01-01

    Following their previous research experiences in human tissue hypoxia, in the present study the authors. investigated the metabolic effects of acute brain hypoxia in a group of patients in course of extracorporeal circulation for aorto-pulmonary bypass. One hundred subjects were treated, half with a placebo and half with acetyl-carnitine to evaluate the effects of oxidative stress in some brain plasmatic metabolites and to verify the effect of acetyl-carnitine on the tissue energy capacity. The levels of lactate, pyruvate, succinate and fumarate showed a significant imbalance due to hypoxia, while the acetyl-carnitine treatment confined the metabolic gradients within physiological limits. This means that during the course of extracorporeal circulation brain hypoxia plays a pathological role assuming the typical picture of cellular oxidative damage and the acetyl-carnitine antagonizes these deleterious effects of hypoxia by a protective mechanism on the energy processes and then on the cellular enzymic activities. In this regard, the d-tyrosine levels, considered as a proteolytic index, confirm the action of acetyl-carnitine on the cell morpho-functional integrity.

In addition, to evaluate its oral treatment potential, we compared the effect of PNS-HLV on global cerebral ischemia/reperfusion and acute myocardial ischemia injury with those of PNS solution, conventional PNS-loaded nanoparticles, and liposomes.Results: In comparison with PNS solution, conventional PNS-loaded nanoparticles and liposomes, PNS-HLV was stable for at least 12 months at 4°C. Satisfactory improvements in the EE% of notoginsenoside R1, ginsenoside Rb1, and ginsenoside Rg1 were shown with the differences in EE% shortened and the greater controlled drug release profiles were exhibited from PNS-HLV. The improvements in the physicochemical properties of HLV contributed to the results that PNS-HLV was able to significantly inhibit the edema of brain and reduce the infarct volume, while it could markedly inhibit H2O2, modified Dixon agar, and serum lactate dehydrogenase, and increase superoxide dismutase (P < 0.05.Conclusion: The results of the present study imply that HLV has promising prospects for improving free drug bioactivity on oral administration.Keywords: liposomes, nanoparticles, panax notoginsenoside, physicochemical properties

    Objective: To observe the therapeutic effect of Xuesaitong soft capsule(血塞通软胶囊,XST)and its effect on platelet counts, coagulation factor 1 (CF1) as well as hemorrheologic indexes in treating patients with acute cerebral infarction (ACI). Methods: Two hundred and four patients with ACI were assigned into two groups, the control group ( n = 96) and the treated group ( n = 108). They were all treated with conventional Western medicines, including mannitol, troxerutin, citicoline, piracetam and aspirin, while to the treated group, XST was given additionally through oral intake, twice a day, 2 capsules each time for 8successive weeks. The clinical efficacy was evaluated according to the nerve function deficits scoring and the changes of platelet count. CF1 and hemorrhe.ological indexes were measured before and after treatment. Results: The total effective rate was 87.0% in the treated group, and 87.5% in the control group, respectively, showing insignificant difference between them. But the markedly effective rate in the treated group (66.7%) was significantly higher than that in the control group (27.1%, P<0.01). The count of platelet was not changed significantly in both groups after treatment, while CF1 inthem evidently lowered at the end of the 4th and 8th weeks of treatment, but showed insignificant difference between the two groups. The hematocrit, whole blood viscosity and plasma viscosity in both groups were all improved significantly after treatment, but also showed insignificant difference in comparison of the two groups. Conclusion: XST has good efficacy in auxiliary treatment of patients with ACI, though its mechanism remains to be further explored.

    Objective To analyze the related factors of cerebral edema after surgery for acute epidural hema-toma. Methods The clinical data of patients with cerebral edema after surgery for acute epidural hematoma from April 2007 to April 2011 were collected and analyzed. The correlation between the incidence & prognosis of cerebral edema and the following factors were investigated: age, sex, surgery preconscious level, clinical status, hematoma volume, hematoma, midline shift level, pupil size, Glasgow coma Scale (GCS), and time from injury to surgery. Results A total of 30 patients suffered cerebral edema after the surgery. ANOVA showed that coma, age, and location of hematoma showed no significant correlation with cerebral edema (P>0.05); Preoperative GCS score, clinical status, time from injury to surgery, shift of midline structures, hematoma volume, and pupil size were significantly related to postoperative cerebral edema (P<0.05); Preoperative pupil size is a relative high risk independent factor of postoperative cerebral edema. Conclusion Patients with acute epidural hematoma may have different degrees of cerebral edema. Therefore, patients should be carefully evaluated before and after surgery for the related factors of cerebral edema, in order to reduce the incidence of this disease.%目的 探讨硬膜外血肿术后脑水肿的相关因素.方法 收集2007年4月至2011年4月硬膜外血肿术后发生脑水肿的30例患者的资料,分析患者术后脑水肿发生及预后与年龄、性别、术前意识水平、临床状态、血肿体积、血肿部位、中线移位程度、瞳孔大小、格拉斯哥昏迷评分(GCS)、受伤至手术时间的关系.结果 63例硬膜外血肿患者术后共有30例患者出现脑水肿,经单因素方差分析显示是否有昏迷、年龄及血肿的部位与术后脑水肿无明显相关(P>.05);术前GCS评分、临床状态、受伤至手术时间、脑中线结构移位程度、血肿量、瞳孔大小、临床

    2009-01-01

    对于急性脑梗死的早期抗凝治疗一直存在争论,大量研究尚未证实早期抗凝治疗能够带来较大益处,并可能增加出血发生率,目前有部分应用抗凝治疗尚缺乏充分的循证医学证据.在临床实践中应遵循指南要求,结合临床经验进行分层和个体化治疗,谨慎把握抗凝治疗的适应证,力求为患者制订最安全有效的治疗方案,密切监测凝血指标,必要时进行"亚抗凝"治疗,将出血的风险控制在最低,使更多患者从中获益.%A large metaanalysis showed that immediate anticoagulation of patients with acute ischemic stroke was not associated with a significant reduction in death or dependency. The heparin data from the International Stroke Trial(IST) suggest that the use of early unmonitored subcutaneous heparin willreduce early stroke recurrence risks, but these benefits can be eliminated by increased hemorrhagic complications. The use of lower doses of heparin may provide more benefits rather than hemorrhagic side effects. We recommend early anticoagulation for various specific stroke subgroups including cardioembolic stroke, progressing stroke, stroke due to large-artery atherosclerotic stenosis, documented intra-luminal thrombus,and deep venous thrombosis prophylaxis.

  17. Cerebral malaria Malaria cerebral

    Full Text Available Is the most common complication of P. falciparum malaria; nearly 90% of people who have suffered CM can recover without neurological problems. Currently there are four hypotheses that explain pathogenesis of CM: cytoadherence and sequestering of parasitized red blood cells to cerebral capillaries; rosette formation and parasitized red blood cells agglutination; production of cytokines and activation of second messengers and opening of the blood-brain barrier. However the main question remains to be answered; how the host-parasite interaction in the vascular space interferes transiently with cerebral function? Recently, the beta amyloid precursor peptide has been employed as marker of neural injury in CM. It is expected that the beta amyloid precursor peptide will help to understand the pathogenesis of CM in complicated patients of endemic areas of Colombia. La malaria Cerebral (MC es la complicación más frecuente de la malaria por P. falciparum; aproximadamente el 90% de las personas que la han padecido se recuperan completamente sin secuelas neurológicas. Aún no se conoce con claridad su patogénesis pero se han postulado cuatro hipótesis o mecanismos posibles: 1 citoadherencia y secuestro de glóbulos rojos parasitados en la microvasculatura cerebral; 2 formación de rosetas y aglutinación de glóbulos rojos parasitados; 3 producción de citoquinas y activación de segundos mensajeros y, 4 apertura de la barrera hematoencefálica. Sin embargo, queda un interrogante sin resolver aún: ¿qué proceso se lleva a cabo para que el parásito, desde el espacio microvascular, pueda interferir transitoriamente con la función cerebral? Recientemente se ha utilizado el precursor de la proteína b-Amiloide como un marcador de daño neuronal en MC; este precursor será de gran ayuda en futuras investigaciones realizadas en nuestro medio que aporten información para comprender la patogénesis de la MC.

  2. Metabolic pattern of the acute phase of subarachnoid hemorrhage in a novel porcine model: studies with cerebral microdialysis with high temporal resolution.

    Christoffer Nyberg

    Full Text Available BACKGROUND: Aneurysmal subarachnoid hemorrhage (SAH may produce cerebral ischemia and systemic responses including stress. To study immediate cerebral and systemic changes in response to aneurysm rupture, animal models are needed. OBJECTIVE: To study early cerebral energy changes in an animal model. METHODS: Experimental SAH was induced in 11 pigs by autologous blood injection to the anterior skull base, with simultaneous control of intracranial and cerebral perfusion pressures. Intracerebral microdialysis was used to monitor concentrations of glucose, pyruvate and lactate. RESULTS: In nine of the pigs, a pattern of transient ischemia was produced, with a dramatic reduction of cerebral perfusion pressure soon after blood injection, associated with a quick glucose and pyruvate decrease. This was followed by a lactate increase and a delayed pyruvate increase, producing a marked but short elevation of the lactate/pyruvate ratio. Glucose, pyruvate, lactate and lactate/pyruvate ratio thereafter returned toward baseline. The two remaining pigs had a more severe metabolic reaction with glucose and pyruvate rapidly decreasing to undetectable levels while lactate increased and remained elevated, suggesting persisting ischemia. CONCLUSION: The animal model simulates the conditions of SAH not only by deposition of blood in the basal cisterns, but also creating the transient global ischemic impact of aneurysmal SAH. The metabolic cerebral changes suggest immediate transient substrate failure followed by hypermetabolism of glucose upon reperfusion. The model has features that resemble spontaneous bleeding, and is suitable for future research of the early cerebral and systemic responses to SAH that are difficult to study in humans.

    2005-01-01

    Purpose: to investigate whether diffusion-weighted imaging (DWI) in magnetic resonance imaging (MRI) provides additional information about the periventricular white matter for the assessment of hydrocephalus. Materials and methods: sixteen MRI examinations (11 with acutely increased cerebral pressure, 5 without symptoms) on 15 patients with hydrocephalus (4 patients with communicating hydrocephalus and 11 patients with obstructive hydrocephalus) were analyzed. One symptomatic patient subsequently became asymptomatic. We investigated the ''apparent diffusion coefficient'' (ADC) in the subcortical and periventricular white matter. The ADCs of the study patients were compared with those of a healthy control group. Results: symptomatic patients with hydrocephalus, 6/11 showed periventricular edema and a significantly higher ADC values in the periventricular region than in the subcortical white matter. 5/11 symptomatic patients showed significantly higher ADC values even in the absence of periventricular interstitial edema (both groups contained patients with communicating and obstructive hydrocephalus).

    Previously, we showed preventive effects of prasugrel, a P2Y12 antagonist, in a non-human primate model of thrombotic middle cerebral artery occlusion (MCAO); however, it remains unclear if P2Y12 inhibition after MCAO reduces cerebral injury and dysfunction. Here we investigated the effects of R-138727, the major active metabolite of prasugrel, on ex vivo platelet aggregation at 5min, 15min, 60min, and 24h after administration to non-human primates (n=3). A single intravenous dose of R-138727 (0.03-0.3mg/kg) resulted in significant and sustained dose-related effects on platelets for up to 24h. R-138727 was administered 1h after MCAO induction, and its effects on thrombosis, cerebral infarction, and neurological deficits were determined (n=8-10). R-138727 (0.3mg/kg) significantly increased total patency rate of the MCA (P=0.0211). Although there was no effect on the patency rate before R-138727 dosing (P=0.3975), it increased 1h after dosing (P=0.0114). R-138727 significantly reduced total ischaemic infarction volumes (P=0.0147), including those of basal ganglia (P=0.0028), white matter (P=0.0393), and haemorrhagic infarction (P=0.0235). Additionally, treatment with R-138727 reduced overall neurological deficits (P=0.0019), including the subcategories of consciousness (P=0.0042), sensory system (P=0.0045), motor system (P=0.0079) and musculoskeletal coordination (P=0.0082). These findings support the possible utility of P2Y12 inhibition during early-onset MCAO to limit the progression and degree of cerebral ischaemia and infarction and also associated neurological deficits.

    Full Text Available In the treatment of patients with suspected acute ischemic stroke, increasing evidence suggests the importance of measuring the volume of the irreversibly injured "ischemic core." The gold standard method for doing this in the clinical setting is diffusion-weighted magnetic resonance imaging (DWI, but many authors suggest that maps of regional cerebral blood volume (CBV derived from computed tomography perfusion imaging (CTP can substitute for DWI. We sought to determine whether DWI and CTP-derived CBV maps are equivalent in measuring core volume.58 patients with suspected stroke underwent CTP and DWI within 6 hours of symptom onset. We measured low-CBV lesion volumes using three methods: "objective absolute," i.e. the volume of tissue with CBV below each of six published absolute thresholds (0.9-2.5 mL/100 g, "objective relative," whose six thresholds (51%-60% were fractions of mean contralateral CBV, and "subjective," in which two radiologists (R1, R2 outlined lesions subjectively. We assessed the sensitivity and specificity of each method, threshold, and radiologist in detecting infarction, and the degree to which each over- or underestimated the DWI core volume. Additionally, in the subset of 32 patients for whom follow-up CT or MRI was available, we measured the proportion of CBV- or DWI-defined core lesions that exceeded the follow-up infarct volume, and the maximum amount by which this occurred.DWI was positive in 72% (42/58 of patients. CBV maps' sensitivity/specificity in identifying DWI-positive patients were 100%/0% for both objective methods with all thresholds, 43%/94% for R1, and 83%/44% for R2. Mean core overestimation was 156-699 mL for objective absolute thresholds, and 127-200 mL for objective relative thresholds. For R1 and R2, respectively, mean±SD subjective overestimation were -11±26 mL and -11±23 mL, but subjective volumes differed from DWI volumes by up to 117 and 124 mL in individual patients.

  16. Cerebral Paragonimiasis.

    Miyazaki, I

    1975-01-01

    The first case of cerebral paragonimiasis was reported by Otani in Japan in 1887. This was nine years after Kerbert's discovery of the fluke in the lungs of Bengal tigers and seven years after a human pulmonary infection by the fluke was demonstrated by Baelz and Manson. The first case was a 26-year-old man who had been suffering from cough and hemosputum for one year. The patient developed convulsive seizures with subsequent coma and died. The postmortem examination showed cystic lesions in the right frontal and occipital lobes. An adult fluke was found in the occipital lesion and another was seen in a gross specimen of normal brain tissue around the affected occipital lobe. Two years after Otani's discovery, at autopsy a 29-year-old man with a history of Jacksonian seizure was reported as having cerebral paragonimiasis. Some time later, however, it was confirmed that the case was actually cerebral schistosomiasis japonica. Subsequently, cases of cerebral paragonimiasis were reported. However, the majority of these cases were not confirmed histologically. It was pointed out that some of these early cases were probably not Paragonimus infection. After World War II, reviews as well as case reports were published. Recently, investigations have been reported from Korea, with a clinicla study on 62 cases of cerebral paragonimiasis seen at the Neurology Department of the National Medical Center, Seoul, between 1958 and 1964. In 1971 Higashi described a statistical study on 105 cases of cerebral paragonimiasis that had been treated surgically in Japan.

    Recently two classification methods based on the location and the extent of thrombosis detected with CT angiography have been introduced: the Boston Acute Stroke Imaging Scale (BASIS) and the clot burden score (CBS). We studied the performance of BASIS and CBS in predicting good clinical outcome (mRS {<=}2 at 90 days) in an acute (<3 h) stroke cohort treated with intravenous thrombolytic therapy. Eighty-three consecutive patients who underwent multimodal CT were analyzed. Binary logistic regression model was used to assess how BASIS, CBS, and cerebral blood volume (CBV) ASPECTS predict favorable clinical outcome. Diagnostic sensitivities and specificities were calculated and compared. Patients with low CBS and CBV ASPECTS scores and major strokes according to BASIS had significantly higher admission NIHSS scores, larger perfusion defects, and more often poor clinical outcome. In logistic regression analysis, CBV ASPECTS, CBS and BASIS were significantly associated with the clinical outcome. The performance of BASIS improved when patients with thrombosis of the M2 segment of the middle cerebral artery were classified as having minor stroke (M1-BASIS). In the anterior circulation, the sum of CBS and CBV ASPECTS (CBSV) proved to be the most robust predictor of favorable outcome. CBV ASPECTS and CBS had high sensitivity but moderate to poor specificity while BASIS was only moderately sensitive and specific. CBS, BASIS, and CBV ASPECTS are statistically robust and sensitive but unspecific predictors of good clinical outcome. Two new derived imaging parameters, CBSV and M1-BASIS, share these properties and may have increased prognostic value. (orig.)

    Gestational diabetes insipidus (GDI) is a rare, self-limited complication of pregnancy. As it is related to excess placental vasopressinase enzyme activity, which is metabolized in the liver, GDI is more common in pregnancies complicated by conditions associated with liver dysfunction. We present a case of a 41-year-old woman at 38 weeks' gestation who presented with pre-eclampsia with severe features, including impaired liver function and renal insufficiency. Following cesarean section she was diagnosed with GDI, which was further complicated by cerebral vasoconstriction as demonstrated by magnetic resonance angiography. This case raises the possibility that cerebral vasoconstriction may be related to the cause of GDI. A high index of suspicion of GDI should be maintained in patients who present with typical signs and symptoms, especially in the setting of pregnancy complications associated with liver dysfunction.

    Full Text Available Traumatic brain injury (TBI is on the rise, especially in today′s fast-paced world. TBI requires not only neurosurgical expertise but also neurointensivist involvement for a better outcome. Disturbances of sodium balance are common in patients with brain injury, as the central nervous system plays a major role in sodium regulation. Hyponatraemia, defined as serum sodium <135 meq/L is commonly seen and is especially deleterious as it can contribute to cerebral oedema in these patients. Syndrome of inappropriate antidiuretic hormone secretion (SIADH, is the most well-known cause of hyponatraemia in this subset of patients. Cerebral Salt Wasting Syndrome (CSWS, leading to renal sodium loss is an important cause of hyponatraemia in patients with TBI. Although incompletely studied, decreased renal sympathetic responses and cerebral natriuretic factors play a role in the pathogenesis of CSWS. Maintaining a positive sodium balance and adequate hydration can help in the treatment. It is important to differentiate between SIADH and CSWS when trying to ascertain a case for patients with acute brain injury, as the treatment of the two are diametrically opposite.

Fifty seven {sup 99m}Tc-Ethylene Cystein Diethylester (ECD) cerebral perfusion SPECT images of 57 patients (male/female=38/19, mean age=56{+-}17 years) with unilateral cerebral infarction were evaluated retrospectively. Patients were divided into subgroups according to the location (left, right) and the onset (acute, chronic) of infarction. Each subgroup was compared with normal controls (male/female=11/1, mean age =36{+-}10 years) in a voxel-by-voxel manner (two sample t-test, p<0.001) using SPM. All 4 subgroups showed hyperperfusion in the ipsilateral cerebral cortex, but not in the contralateral cerebral cortex. Chronic left and right infarction groups revealed hyperperfusion in the ipsilateral primary sensorimotor cortex, meanwhile, acute subgroups did not. Contralateral cerebellar hyperperfusion was also demonstrated in the chronic left infarction group. Using {sup 99m}Tc-ECD SPECT, we observed ipsilateral cerebral and contralateral cerebeller hyperperfusion in patients with cerebral infarction. However, whether these findings are related to the recovery of cerebral functions should be further evaluated.

    Objective To study the vascular reserve of large cerebral arteries in patients with acute cerebral thrombosis with more than 50% stenosis of the intracranial arteries. Methods Seventeen patients with acute cerebral thrombosis with magnetic resonance artery( MRA )/ transcranial doppler ultrasonography ( TCD ) confirmed stenosis of the intracranial arteries, were recruited in the study. Patients were examined by TCD before admission and 2 hour after oral Diamox treatment two days later. The changes of the blood flow before and after Diamox were compared in 187 large arteries.Results The cerehral blood flow was increased obviously following diamox. The blood flows in the right internal carotid artery( RICA ), right middle cerebral artery ( RMCA ) , right posterior cerebral artery( RPCA ) were increased after diamox but the difference did not reach statistically significance( P = 0.086,0.258 ,0.084 )but, other arteries increased cerebral blood flow significantly( P < 0.05 ). There was more increase in blood flow in non-stenosis arteries than in stenosis arteries but the difference did not reach statistically significance ( P = 0.08 ). There were no significant differences in the blood flow changes hetween moderate stenosis arteries and severe stenosis arteries ( P = 0.65 ). Conclusions Diamox test in TCD can precisely measure the large cerebral artery vascular reserve. Stenosis arteries have a decline tendency in vascular reserve compared with non-stenosis arteries. However,there is not significant difference in vascular reserve between moderate stenosis arteries and severe stenosis.%目的 对伴有颅内动脉狭窄的缺血性脑卒中患者采用口服乙酰唑胺实验研究颅内大动脉血流储备能力.方法 对17例经磁共振血管显影(magnetic resonance angiography, MRA)/或经颅多谱勒超声(transcranial doppler ultrasonography, TCD)证实颅内动脉狭窄大于50%的缺血性脑卒中患者,按TOAST分型为动脉粥样硬

    Huisman, T.A.G.M.; Martin, E.; Willi, U.V. [Dept. of Diagnostic Imaging and Radiology, University Children' s Hospital Zurich (Switzerland); Holzmann, D. [Dept. of Otorhinolaryngology, University Children' s Hospital Zurich, Zurich (Switzerland)

    2001-09-01

    This was a retrospective study to determine different etiologies of cerebral venous thrombosis (CVT) in childhood and to correlate extent and location of thrombosis with the etiology and the age of the child as well as the final outcome. In addition, the radiologic approach is discussed. This was a retrospective analysis of 19 children with CVT. The children were examined by contrast-enhanced dynamic CT. Radiologic findings were correlated with the etiology of CVT. Cerebral venous thrombosis is not as infrequent in children as has been thought. Cerebral venous thrombosis in children can occur due to trauma (n=9), infections (n=7), or coagulation disorders (n=3). Extent and location of thrombosis, as well as complications, final outcome, and therapy, depend on the etiology. Computed tomography remains a valuable primary imaging modality in the diagnosis of CVT in the acutely injured or diseased child. (orig.)

    2015-01-01

    Objective Several recent intraventricular hemorrhage prevention bundles include midline head positioning to prevent potential disturbances in cerebral hemodynamics. We aimed to study the impact of head position change on regional cerebral saturations (SctO2) in preterm infants (< 30 weeks GA) during the first three days of life. Study Design Bilateral SctO2 was measured by near infrared spectroscopy. The infant's head was turned sequentially to each side from midline (baseline) in thirty-minute intervals while keeping the body supine. Bilateral SctO2 before and after each position change were compared using paired t-test. Results In relatively stable preterm infants (gestational age 26.5±1.7 weeks, birth weight 930±220g; n=20), bilateral SctO2 remained within normal range (71.1% - 75.3%) when the head was turned from midline position to either side. Conclusion Stable preterm infants tolerated brief changes in head position from midline without significant alternation in bilateral SctO2; the impact on critically ill infants needs further evaluation.

  9. Cerebral hemodynamics: concepts of clinical importance

    2012-05-01

    Full Text Available Cerebral hemodynamics and metabolism are frequently impaired in a wide range of neurological diseases, including traumatic brain injury and stroke, with several pathophysiological mechanisms of injury. The resultant uncoupling of cerebral blood flow and metabolism can trigger secondary brain lesions, particularly in early phases, consequently worsening the patient's outcome. Cerebral blood flow regulation is influenced by blood gas content, blood viscosity, body temperature, cardiac output, altitude, cerebrovascular autoregulation, and neurovascular coupling, mediated by chemical agents such as nitric oxide (NO, carbon monoxide (CO, eicosanoid products, oxygen-derived free radicals, endothelins, K+, H+, and adenosine. A better understanding of these factors is valuable for the management of neurocritical care patients. The assessment of both cerebral hemodynamics and metabolism in the acute phase of neurocritical care conditions may contribute to a more effective planning of therapeutic strategies for reducing secondary brain lesions. In this review, the authors have discussed concepts of cerebral hemodynamics, considering aspects of clinical importance.

    Schroeder, T; Sillesen, H

    1987-01-01

    Dihydralazine is widely used for acute control of hypertension. In experimental studies it seems to dilate cerebral resistance vessels and increase intracranial pressure. However, the effect on cerebral blood flow (CBF) in man has been little studied. Measurements of CBF were performed with the i...... the period of study, in median 16, 27 and 23% at the three periods of measurements, respectively. The arterial blood pressure remained unchanged, whereas heart rate increased significantly. During CO2 inhalation, CBF increased on average 29%. Thus, the cerebral vasodilation exerted by a small i.v. dose...

    2007-01-01

    BACKGROUND: Previously, only single short-time low-dose hyperbaric oxygenation (HBO) protocol was administrated to treat acute ischemic stroke in early stage and the conflicting results were obtained. There are few studies to report the outcome of administering long-time (can cover all the natural pathologic progression period) high-dose HBO to treat the disease.OBJECTIVE: To evaluate the therapeutic effect between two kinds of high-dose hyperbaric oxygenation on super-early stage of acute permanent middle cerebral artery occlusion (MCAO) in rats.DESIGN: A randomized controlled experimental study.SETTING: Beijing Tiantan Hospital, Capital Medical University; Beijing Research Institute of Neurosurgery.MATERIALS: Seventy-four male SD rats, aged 2.5 months old, weighing (280±20) g, were provided by the Animal Institute, Chinese Academy of Medical Sciences. Hyperbaric oxygenation device was hyperbaric air cabin in which there was a self-made pure oxygen animal experimental cabin (made in China).METHODS: This experiment was carried out in the municipal laboratory of Beijing Tiantan Hospital affiliated to Capital Medical University and Beijing Research Institute of Neurosurgery. ① Experimental intervention: All the rats were developed into models of permanent MCAO by suture embolism. Then, they were randomly divided into two HBO groups (9hours and 18 hours) and control group, with 24 rats in each as well as 3-hour ultrastructure control group, with 2 rats. After being modeled for 3 hours, rats in the two HBO groups stayed in the hyperbaric cabin for 9 hours and 18 hours,separately. Rats in the 9-hour HBO group inhaled pure oxygen at hours 1, 3, 5, 7 and 9, and hyperbaric air at hours 2, 4, 6 and 8. Rats in the 18-hour HBO group inhaled pure oxygen at hours 1, 3, 5, 7, 9, 11, 13, 15 and 17, and hyperbaric air at hours 2, 4, 6, 8, 10 12, 14, 16 and 18.

    2014-01-01

    Full Text Available Background. Nontraumatic cerebral air embolism cases are rare. We report a case of an air embolism resulting in cerebral infarction related to angioinvasive cavitary aspergillosis. To our knowledge, there have been no previous reports associating these two conditions together. Case Presentation. A 32-year-old female was admitted for treatment of acute lymphoblastic leukemia (ALL. Her hospital course was complicated by pulmonary aspergillosis. On hospital day 55, she acutely developed severe global aphasia with right hemiplegia. A CT and CT-angiogram of her head and neck were obtained demonstrating intravascular air emboli within the left middle cerebral artery (MCA branches. She was emergently taken for hyperbaric oxygen therapy (HBOT. Evaluation for origin of the air embolus revealed an air focus along the left lower pulmonary vein. Over the course of 48 hours, her symptoms significantly improved. Conclusion. This unique case details an immunocompromised patient with pulmonary aspergillosis cavitary lesions that invaded into a pulmonary vein and caused a cerebral air embolism. With cerebral air embolisms, the acute treatment option differs from the typical ischemic stroke pathway and the provider should consider emergent HBOT. This case highlights the importance of considering atypical causes of acute ischemic stroke.

    Full Text Available One third of cases of cerebral ischemia have no clear etiology. A humoral response to the atherosclerotic plaques components beta2-glycoprotein l (beta2-gpl and heat-shock proteins (Hsp might be involved in the pathogenesis of stroke. This case-control study includes a complete profile of anti-beta2-gpl antibodies and testing of IgG antibodies to the 60/65 kilodaltons (kDa Hsp in stroke patients. Ninety-three patients with acute ischemic stroke and 93 controls were evaluated for age, sex, race, hypertension, smoking, previous cardiopathy, diabetes mellitus, hypercholesterolemia and previous history of cerebral ischemia. lgG/lgM/lgA anticardiolipin (aCL and anti-beta2-gpl antibodies, as well as lgG antibodies to human 60 kDa Hsp and to Mycobacterium bovis 65 kDa Hsp, were detected by immunoassay. Adjusted odds ratios (OR were calculated by logistic regression. The adjusted OR for IgA anti-beta2-gpl antibodies was 4.6 (90%Cl 1.5 to 14.3; p = 0.025. The non-adjusted OR for IgG antibodies to Hsp 60 was 26.1. The adjusted OR for IgG antibodies to Hsp 65 was 3.2 (90%Cl 1.2 to 8.3; p = 0.044. The adjusted OR for lgG to any Hsp (60 or 65 was 4.8 (90%Cl 1.9 to 12.1; p = 0.006. This study demonstrates that elevated IgA anti-beta2-gpl and lgG anti-Hsp 60/65 antibodies are associated with increased risk of ischemic stroke. The association occurred independently of other risk factors. This humoral response might link autoimmunity, thrombophilia and atherosclerosis in stroke patients.Um terço dos casos de isquemia cerebral não apresenta etiologia clara.

    Objective: HIV enters the brain soon after infection causing neuronal damage and microglial/astrocyte dysfunction leading to neuropsychological impairment. We examined the impact of HIV on resting cerebral blood flow (rCBF) within the lenticular nuclei (LN) and visual cortex (VC). Methods: This cross-sectional study used arterial spin labeling MRI (ASL-MRI) to measure rCBF within 33 HIV+ and 26 HIV− subjects. Nonparametric Wilcoxon rank sum test assessed rCBF differences due to HIV serostatus. Classification and regression tree (CART) analysis determined optimal rCBF cutoffs for differentiating HIV serostatus. The effects of neuropsychological impairment and infection duration on rCBF were evaluated. Results: rCBF within the LN and VC were significantly reduced for HIV+ compared to HIV− subjects. A 2-tiered CART approach using either LN rCBF ≤50.09 mL/100 mL/min or LN rCBF >50.09 mL/100 mL/min but VC rCBF ≤37.05 mL/100 mL/min yielded an 88% (29/33) sensitivity and an 88% (23/26) specificity for differentiating by HIV serostatus. HIV+ subjects, including neuropsychologically unimpaired, had reduced rCBF within the LN (p = 0.02) and VC (p = 0.001) compared to HIV− controls. A temporal progression of brain involvement occurred with LN rCBF significantly reduced for both acute/early (<1 year of seroconversion) and chronic HIV-infected subjects, whereas rCBF in the VC was diminished for only chronic HIV-infected subjects. Conclusion: Resting cerebral blood flow (rCBF) using arterial spin labeling MRI has the potential to be a noninvasive neuroimaging biomarker for assessing HIV in the brain. rCBF reductions that occur soon after seroconversion possibly reflect neuronal or vascular injury among HIV+ individuals not yet expressing neuropsychological impairment.

    死后出血转化独立相关,其与急性脑梗死远期预后的关系有待进一步研究。%Objective To investigate the impact of using antithrombotic drugs (anticoagulants or antiplatelet aggregation drugs)before the onset of cerebral infarction on hemorrhagic transformation after acute cerebral infarction. Methods The consecutive patients with acute cerebral infarction from Chengdu Stroke Registry Project admitted to the Department of Neurology,West China Hospital,Sichuan University from January 1,2004 to January 1,2014 were enrolled. The baseline data on admission,previous usage of anticoagulants and anti-platelet aggregation drugs,as well as CT/ MRI and other imaging data of all patients were collected. According to the results of CT/ MRI reexamined at 72 h after admission,the patients with hemorrhagic transformation were enrolled into a hemorrhagic transformation group;the patients with non-hemorrhagic transformation were enrolled into a non-hemorrhagic transformation group according to the ratio of 1 ∶ 1. Their gender and age were matched with the hemorrhagic transformation group. The baseline data and drug used of the patients in both groups were compared. The differences of risk factors between the two groups were analyzed with multivariate Logistic regression analysis. The relationship between hemorrhagic transformation and premorbid use of antithrombotic drugs were observed.

    Radioisotope brain imaging has focused mainly on regional cerebral blood flow (rCBF). However the use of ligand which go to specific receptor sites is being introduced in pediatrics, mainly psychiatry. rCBF is potentially available in many institutions, especially with the availability of multi-headed gamma cameras. The use of this technique in pediatrics requires special attention to detail in the manner of data acquisition and handling the child. The interpretation of the rCBF study in a child requires knowledge of normal brain maturation. The major clinical use in pediatrics is epilepsy because of the advances in surgery and the frequency of complex partial seizures. Other indications in pediatric neurology include brain death, acute neurological loss including stroke, language disorders, cerebral palsy, hypertension due to renovascular disease, traumatic brain injury and migraine. There are pediatric physiological conditions in which rCBF has been undertaken, these include anorexia nervosa, autism, Gilles de la Tourette syndrome (GTS) and attention deficit disorder-hyperactivity (ADHD). Research using different ligands to specific receptor sites will also be reviewed in pediatrics.

    Astrocyte swelling and the subsequent increase in intracranial pressure and brain herniation are major clinical consequences in patients with acute hepatic encephalopathy. We recently reported that conditioned media from brain endothelial cells (ECs) exposed to ammonia, a mixture of cytokines (CKs) or lipopolysaccharide (LPS), when added to astrocytes caused cell swelling. In this study, we investigated the possibility that ammonia and inflammatory agents activate the toll-like receptor 4 (TLR4) in ECs, resulting in the release of factors that ultimately cause astrocyte swelling. We found a significant increase in TLR4 protein expression when ECs were exposed to ammonia, CKs or LPS alone, while exposure of ECs to a combination of these agents potentiate such effects. In addition, astrocytes exposed to conditioned media from TLR4-silenced ECs that were treated with ammonia, CKs or LPS, resulted in a significant reduction in astrocyte swelling. TLR4 protein up-regulation was also detected in rat brain ECs after treatment with the liver toxin thioacetamide, and that thioacetamide-treated TLR4 knock-out mice exhibited a reduction in brain edema. These studies strongly suggest that ECs significantly contribute to the astrocyte swelling/brain edema in acute hepatic encephalopathy, likely as a consequence of increased TLR4 protein expression by blood-borne noxious agents.

    Carotid angioplasty with stenting is a reliable method of primary and secondary prevention of ischaemic stroke in patients with stenosing lesions of the internal carotid artery. However, carrying out such operations is sometimes associated with risk for the development of intraoperative impairments of cerebral circulation due to arterioarterial embolism in cerebral arteries, as well as vasospasm. Presented herein are the results of following up a total of 64 patients with pronounced atherosclerotic lesions of internal carotid arteries (>70%) - "symptomatic" and "asymptomatic", undergoing carotid stenting. Acute foci of ischaemia in the brain after stenting according to the findings of diffusion-weighted magnetic resonance tomography were revealed in 40% of cases, and in only 6% of patients they manifested themselves by symptoms of acute cerebral circulatory impairment. We revealed a direct correlation between the number, size of infarctions in the brain, and the appearance of neurological symptomatology. Intraoperative monitoring of blood flow in the middle cerebral artery during stenting makes it possible to predict the appearance of acute foci of cerebral ischaemia, to specify the genesis of perioperative stroke, as well as to evaluate clinical significance of vasospasm and material microembolism. The obtained findings should concentrate neurologists' attention on active postoperative follow up of patients subjected to carotid angioplasty with stenting in order to perform adequate personified neuroprotective correction, including preventive one.

    The aim of our research is to study hemodynamic and embolic situation during the carotid endarterectomy (CEA), carotid angioplastic and stenting (CAS), and to reveal the prognostic significance of the data provided by intraoperative monitoring of the brain blood flow in exposing acute ischemic lesions in brain. Intraoperative monitoring of blood flow in artery ophthalmic vas carried out with 60% of patients, in the middle cerebral artery-with 40% during the main stages of CEA, and with 64 patients in the middle cerebral artery during CAS. The comparison of the data of intraoperative monitoring of blood flow in middle cerebral artery with the result of brain diffusion-weighted magnetic resonance imaging (DW-MRI) 24 hours after the operation shows, that solid microembolic signals and vasospasm are prognostic signals (sensibility and specifics make up 95%) in the development of acute ischemic cerebral lesions. The monitoring of blood flow in artery ophthalmic is of the greatest diagnostic value in estimation of the hemodynamic situation, but it is of the lowest practical value in detecting microembolic signals. According to the data of the intraoperative blood flow monitoring in middle cerebral artery in group CEA the development of acute ischemic cerebral lesions were predicted with 11,1% of patients and the cause of postoperative stroke, developed by 2,9% of the patients, was specified. According to the result of DW-MRI, acute ischemic cerebral lesions were diagnosed with 21% of patients, that is, 18% of ischemic cerebral lesions were asymptomatic. In group CAS ischemic cerebral lesions were prognosed with 30% of patients, actually they were later detected with 40,6% of cases by means of DW-MRI. According to the data of intraoperative of blood flow monitoring the cause of the development of postoperative stroke was specified in 6,2% of cause; in 34,4% of cause the acute ischemic cerebral lesions were asymptomatic.

    Sildenafil citrate (Viagra) is one of the frequently prescribed drugs for men with erectile dysfunction. We describe a 52-year-old man with bilateral middle cerebral artery (MCA) territory infarction after sildenafil use. He ingested 100 mg of sildenafil and about 1 h later, he complained of chest discomfort, palpitation and dizziness followed by mental obtundation, global aphasia and left hemiparesis. Brain magnetic resonance imaging documented acute bilateral hemispheric infarction, and cerebral angiography showed occluded bilateral MCA. Despite significant bilateral MCA stenosis and cerebral infarction, systemic hypotension persisted for a day. We presume that cerebral infarction was caused by cardioembolism with sildenafil use.

    Central nervous system (CNS) thrombotic events are a well-known complication of acute lymphoblastic leukemia (ALL) induction therapy, especially with treatments including l-asparaginase (l-ASP). Data on risk factors and clinical evolution is still lacking in adult patients. We report on the clinical evolution of 22 CNS venous thrombosis cases occurring in 708 adults treated for ALL or lymphoblastic lymphoma (LL) with the Group for Research on Adult Acute Lymphoblastic Leukemia (GRAALL)-induction protocol, which included eight L-ASP (6,000 IU/m(2) ) infusions. The prevalence of CNS thrombosis was 3.1%. CNS thrombosis occurred after a median of 18 days (range: 11-31) when patients had received a median of three l-ASP injections (range: 2-7). Patients with CNS thrombosis exhibited a median antithrombin (AT) nadir of 47.5% (range: 36-67%) at Day 17 (range: D3-D28), and 95% of them exhibited AT levels lower than 60%. There were no evident increase in hereditary thrombotic risk factors prevalence, and thrombosis occurred despite heparin prophylaxis which was performed in 90% of patients. Acquired AT deficiency was frequently detected in patients with l-ASP-based therapy, and patients with CNS thrombosis received AT prophylaxis (45%) less frequently than patients without CNS thrombosis (83%), P = 0.0002). CNS thrombosis was lethal in 5% of patients, while 20% had persistent sequelae. One patient received all planned l-ASP infusions without recurrence of CNS thrombotic whereas l-ASP injections were discontinued in 20 patients during the management of thrombosis without a significant impact on overall survival (P = 0.4).

    Full Text Available BACKGROUND: Early signs of ischaemic stroke on computerised tomography (CT scanning are subtle but CT is the most widely available diagnostic test for stroke. Scoring methods that code for the extent of brain ischaemia may improve stroke diagnosis and quantification of the impact of ischaemia. METHODOLOGY AND PRINCIPAL FINDINGS: We showed CT scans from patients with acute ischaemic stroke (n = 32, with different patient characteristics and ischaemia signs to doctors in stroke-related specialties world-wide over the web. CT scans were shown twice, randomly and blindly. Observers entered their scan readings, including early ischaemic signs by three scoring methods, into the web database. We compared observers' scorings to a reference standard neuroradiologist using area under receiver operator characteristic curve (AUC analysis, Cronbach's alpha and logistic regression to determine the effect of scales, patient, scan and observer variables on detection of early ischaemic changes. Amongst 258 readers representing 33 nationalities and six specialties, the AUCs comparing readers with the reference standard detection of ischaemic signs were similar for all scales and both occasions. Being a neuroradiologist, slower scan reading, more pronounced ischaemic signs and later time to CT all improved detection of early ischaemic signs and agreement on the rating scales. Scan quality, stroke severity and number of years of training did not affect agreement. CONCLUSIONS: Large-scale observer reliability studies are possible using web-based tools and inform routine practice. Slower scan reading and use of CT infarct rating scales improve detection of acute ischaemic signs and should be encouraged to improve stroke diagnosis.

    Objective To evaluate the application of color Doppler ultrasound (CDU) on the carotid arteriosclerosis with acute cerebral infarction. Methods Thirty cases of carotid arteriosclerosis with acute cerebral infarction were investigated using CDU,and the ultrasound findings were compared with those of digital subtraction arteriography (DSA) which served as the diagnosis gold standard method. Kappa test was performed between the results of CDU and DSA. Results The sensitivity,specificity and accuracy of B-mode and color image in the diagnosis of above the moderate degree carotid artery stenosis and occlusion were 95.5 %, 94.7 % and 95.0 %, respectively. And CDU for above the moderate degree of stenosis, the sensitivity, specificity and accuracy were 77.3%, 97.4% and 90.0%,respectively. Kappa test showed the agreement between CDU and DSA for the diagnosis of carotid artery stenosis was good, CDU morphologic mensurate Kappa = 0. 787, CDU hemodynamics mensurate Kappa = 0.669. Conclusion The agreement between CDU and DSA in the evalution of carotid artery stenosis is good. For the most of moderate and serious degrees of stenosis,CDU is a substitution for DSA. Additionally, the therapeutic regimen could be decided on the basis of the findings of CDU for 70%-99% degree of stenosis.%目的 评价彩色多普勒超声(colorDoppler ultrasound,CDU)在诊断急性脑梗死患者颈动脉硬化病变的价值.方法 应用CDu对30倒急性脑梗死患者颅外段颈动脉血管检测.每例患者均同时行数字减影血管造影(DSA)检查,并将2种检查方法的结果进行一致性检验(Kappa检验).结果 以DSA检查结果为金标准,得出了二维彩色超声诊断颈动脉中重度以上狭窄及闭塞的敏感度、特异度及准确度分别为95.5%、94.7%、95.0%,CDU频谱诊断中重度以上狭窄及闭塞的敏感度、特异度及准确度分别为77.3%、97.4%、90.0%.一致性检验(Kappa检验)结果表明CDU和DSA2种方法的检查结果的一致性良

    Full Text Available Abstract Background Ischemia/reperfusion leads to inflammation and oxidative stress which damages membrane highly polyunsaturated fatty acids (HPUFAs and eventually induces neuronal death. This study evaluates the effect of the administration of Pistacia lentiscus L. essential oil (E.O., a mixture of terpenes and sesquiterpenes, on modifications of fatty acid profile and endocannabinoid (eCB congener concentrations induced by transient bilateral common carotid artery occlusion (BCCAO in the rat frontal cortex and plasma. Methods Adult Wistar rats underwent BCCAO for 20 min followed by 30 min reperfusion (BCCAO/R. 6 hours before surgery, rats, randomly assigned to four groups, were gavaged either with E.O. (200 mg/0.45 ml of sunflower oil as vehicle or with the vehicle alone. Results BCCAO/R triggered in frontal cortex a decrease of docosahexaenoic acid (DHA, the membrane highly polyunsaturated fatty acid most susceptible to oxidation. Pre-treatment with E.O. prevented this change and led further to decreased levels of the enzyme cyclooxygenase-2 (COX-2, as assessed by Western Blot. In plasma, only after BCCAO/R, E.O. administration increased both the ratio of DHA-to-its precursor, eicosapentaenoic acid (EPA, and levels of palmytoylethanolamide (PEA and oleoylethanolamide (OEA. Conclusions Acute treatment with E.O. before BCCAO/R elicits changes both in the frontal cortex, where the BCCAO/R-induced decrease of DHA is apparently prevented and COX-2 expression decreases, and in plasma, where PEA and OEA levels and DHA biosynthesis increase. It is suggested that the increase of PEA and OEA plasma levels may induce DHA biosynthesis via peroxisome proliferator-activated receptor (PPAR alpha activation, protecting brain tissue from ischemia/reperfusion injury.
