The effect of ischemia on catecholamine and 5-hydroxytryptamine (5-HT) levels in brain cortex was examined in the gerbil stroke model. Unilateral common carotid artery occlusion produced bilateral decrease in cortical dopamine levels in gerbils both symptomatic and asymptomatic of cerbral ischemia. The 5-HT progressively decreased only in the occluded hemisphere of ischemic animals. In p-chloro...

background: free-living amoebae (fla) including acanthamoeba spp. and hartmannella spp. are the causative agents of serious corneal infection especially within contact lens wearers. thus contact lenses and their storage case could be a suitable niche for potentially pathogenic amoebae. the main objective of the present study was to evaluate the contamination of contact lenses to free living amo...

background: plasmodium vivax is the most widespread species of plasmodium in humans and causing about 80 million clinical cases annually. this study was under-taken to detect p. vivax in asymptomatic treated vivax malaria patients to trace la-tent/sub-patent malaria infection. method: the venous blood of all detected cases with p. vivax in bashagard, minab and roodan districts in hormozgan prov...

OBJECTIVE To evaluate the use of noninvasive procedures for the detection of myocardial ischemia and its relation with other coexistent clinical factors in patients with asymptomatic type 2 diabetes mellitus. SUBJECTS AND METHODS A total of 42 patients with type 2 diabetes mellitus, aged 41-72 years with no clinical history suggestive of coronary heart disease, were evaluated for silent myoca...

BACKGROUND AND PURPOSE The management of asymptomatic carotid stenosis found before vascular or coronary surgery is unclear from the literature. We aimed to define the relation of carotid stenosis to perioperative stroke in all patients, symptomatic and asymptomatic, and so determine a policy for the management of asymptomatic carotid stenosis in patients requiring major surgery. METHODS We c...

BACKGROUND Asymptomatic patients with severe coronary atherosclerosis may have a normal resting electrocardiogram and stress test. AIM To assess the yield of Gated Single Photon Emission Computer Tomography (SPECT) for the screening of silent myocardial ischemia in type 2 diabetic patients. MATERIAL AND METHODS Electrocardiogram, stress test and gated-SPECT were performed on 102 type 2 diab...
