to evaluate pathogenicity of 3 chicken anemia virus isolates-cv1, cv2 and cv3 respectively - the current experiment carried out. after tittering of the viruses, 30 one day old spf chicks were grouped and intramuscularly inoculated with each isolate in a separate group. two other groups as positive and control groups were inoculate with a live vaccine virus and normal saline respectively. during...

Many studies in hypertensive humans and animals have shown that increased blood viscosity is in direct relation with essential hypertension. The aim of our studies was to investigate the effects of chronic hematocrit value changes on arterial blood pressure and kidney function in genetically induced hypertension. To this end, we studied the effects of several interventions, designed to increase...

background: preeclampsia is the most prevalent complication of pregnancy and one ihird cause of death in pregnant women. developing of a screening test may help to early diagnosis. this study performed to compare diagnostic value of the roll over test and hematocrit level in early detection of preeclampsia.        methods: 660 pregnant women with gestational age of 24-28 weeks referred totamin ...

BACKGROUND AND PURPOSE This study investigated whether in patients with internal carotid artery occlusion the regional cerebral hematocrit correlates with cerebral hemodynamics or metabolic state and, if so, how the regional cerebral hematocrit changes in the hemodynamically compromised region. METHODS We used positron emission tomography to study seven patients with unilateral internal carot...

OBJECTIVE Previous work has found cerebral oxygen extraction to decrease during hypothermic cardiopulmonary bypass in children. To elucidate cardiopulmonary bypass factors controlling cerebral oxygen extraction, we examined the effect of perfusate temperature, pump flow rate, and hematocrit value on cerebral hemoglobin-oxygen saturation as measured by near infrared spectroscopy. METHODS Forty...
