Prevalence of pulmonary arterial hypertension (PAH) was studied by echocardiography and Doppler in 43 splenectomized patients with various disorders 1-20 years after splenectomy. Pulmonary arterial hypertension was detected only in thalassemia major, intermedia, hereditary sphereocytosis and myelofibrosis groups comprising a total of 21 patients. Six patients out of 21 was found to have PAH wit...

The etiology of cerebral hemiatrophy may be congenital or acquired. Trauma, infection, vascular abnormality, ischemic and hemorrhagic conditions may be the etiologic factors in acquired type. There is limited information about its association with other disorders in the literature. We presented three new cases of cerebral hemiatrophy associated with some hematological and developmental disorder...

An improved radiochemical method to measure the o-aminoJevulinic acid (ALA) synthetase activity in human bone marrow erythroblasts by incubating bone marrow cell homogenate with 14C-succinate and succinyl CoA generating system has been reported. Studies were made to obtain the optimal conditions for the enzyme assay and to confirm the reliability of the assay procedures. ALA-synthetase in eryth...

Abstract This paper considers a mathematical model that accounts for the hematological disorders of blood in its flow human arteries. Blood is described as Newtonian fluid but with viscosity function hematocrit, plasma viscosity, and shape factor red cells. The artery modeled flexible circular pipe oscillatory. solved using HAM (Homotopy Analysis Method), an approximate analytical method, we co...
