Background: The role of uric acid as a risk factor for vascular disease and acute stroke is controversial and there is little information about it. In this study, we determined serum uric acid levels in patients with acute stroke and assessed its relationship with cerebrovascular risk factors. Methods: In this cross sectional study, we assessed patients with acute stroke who were admitted in F...

the exact role of the epithelial lining of the trachea in modulating the bronchial tone is controversial. the present study was an attempt to verify the role of both prostaglandins and mast cells in the acute phase of acid inspiration in rat. four groups (n = 6) of n. mari rats were employed. the first group was used as placebo control, and normal saline was injected. to the second group hydroc...

background: opioid peptides and their receptors are present in the majority of body tissues including gastrointestinal tract.  heroin is one of the opioid derivatives that abuse increasingly today.  so far, there is no study on the effect of acute heroin administration on gastric acid and pepsin secretion.   objective:  to define the effect of the acute heroin consumption on basal and vagal-sti...

the present study aimed to compare the serum level of uric acid in patients with and without heart failure and also to determine the association between uric acid level and clinical status by killip class in patients with stemi. this case-control study was conducted on 50 consecutives as control group and 50 patients with acute heart failure, (20 patients had acute stemi), who documented by bot...

Background: Previous studies show that serum level of uric acid is significantly correlated with mortality and functional outcome in patients with ischemic stroke and according to some other studies, ischemic stroke is associated with stenosis of some stenoisis of somespecific brain vessels. The aim of this study was to investigate the frequency of hyperuricemia and its associa...

conclusions acute and chronic administration of ellagic acid had anxiolytic property. also, the most effective dose of ellagic acid was 30 mg/kg. pretreatment with flumazenil reversed the beneficial effect of ellagic acid and diazepam on anxiety. it is likely that the anxiolytic effect of ellagic acid is largely mediated by activation of gabaa receptor. results acute and chronic application of ...

recent studies show that, inflammation plays an important role in the initiation and progression of atherosclerosis and in the pathogenesis of acute cardiovascular events. there is a possible association between ventricular dysfunction following acute myocardial infarction and high sensitivity c-reactive protein (hs-crp) and uric acid. in this study we assessed the relationship between hs-crp a...

Objective(s): Ethanol withdrawal following chronic use, is an important challenge clinically. In this study, the effect of clavulanic acid was evaluated on the symptoms of ethanol withdrawal in rats. Materials and Methods: Alcohol dependence was induced by the gavage of ethanol (10% v/v, 2 g/kg), twice daily for 10 days. Clavulanic acid ...
