The wide-spread assumption that doping with erythropoietin or blood transfusion is only effective by increasing arterial blood O2 content because of rising hematocrit is not self-evident. "Natural blood dopers" (horses, dogs) increase both hematocrit and circulating blood volume during exercise by releasing stored erythrocytes from the spleen. Improvement of aerobic performance by augmenting he...

in 1979, a community health survey for the purpose of establishing population babe. services were conducted in the villages of region of isfahan with a population of about 10,000. the target group involved males and females with in the age group of more than one year old. the population under study, 617 males and 565 females who were selected by household random sampling, where examined for the...

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...

BACKGROUND AND PURPOSE The pathophysiology of crossed cerebellar diaschisis (CCD) remains to be elucidated. In CCD, the metabolic suppression resulting from deafferentation may cause vasoconstriction, which may result in a decrease in cerebral blood volume (CBV) and may differentially affect the flows of red blood cells and of plasma. The purpose of this study was to investigate whether CCD dec...

We prospectively evaluated the accuracy of the 2007 World Health Organization (WHO) criteria for diagnosing polycythemia vera (PV), especially in "early-stage" patients. A total of 28 of 30 patients were diagnosed as PV owing to an elevated Cr-51 red cell mass (RCM), JAK2 positivity, and at least 1 minor criterion. A total of 18 PV patients did not meet the WHO criterion for an increased hemogl...

D URING measurements of total body red cell volume by the Cr51-technic in this laboratory, normal or elevated values were observed in several patients with moderate “anemia”, as judged by the hematocrit of peripheral venous blood. #{176} In each instance, marked to massive splenomegaly was present and increased localization of red cell radioactivity in the spleen was noted by body surface scann...
