background recombinant human erythropoietin (rhuepo) treatment can increase hemoglobin levels and decrease transfusion requirements. this study aims to investigate how blood transfusion influences hemoglobin levels in patients receiving rhuepo for 12 weeks. materials and methods this was a case-control study of 60 patients less than 15 years with anemia and a solid tumor in any location between...

background:the dynamic binding capacity (dbc) of a chromatography matrix in protein purification is the amount of the total protein absorbed into the matrix, before occurrence of a significant break in the breakthrough curve. optimization of the process criteria for maximum dbc avoids extra process scale-up and reduces the processing time, costs and protein loss. taguchi method is a simple usef...

The expression of adrenomedullin (ADM) in injured tissue of rat spinal cord was observed and the effect of recombinant human erythropoietin was analyzed. A total of 45 Sprague-Dawley rats were selected and divided into 3 equal groups including, a sham-operation group in which rats received an excision of vertebral plate; a spinal cord injury model group and a recombinant human erythropoietin gr...

Despite improved survival, many preterm infants undergo subsequent neurodevelopmental impairment. To date, no neuroprotective therapies have been implemented into clinical practice. Erythropoietin, a haematopoietic cytokine used for treatment of anaemia of prematurity, has been shown to have neuroprotective and neuroregenerative effects on the brain in many experimental studies. The aim of the ...

Recombinant human erythropoietin produced in transfected Chinese hamster ovary cells is glycosylated much the same way as the erythropoietin present in human urine. To determine the role of carbohydrates in the stability of recombinant human erythropoietin in vivo, [125I]-labeled recombinant erythropoietin was intravenously infused into rats. The erythropoietin was slowly cleared from the blood...

Background: Erythropoietin (EPO) was first known as a factor for red blood cell proliferation and differentiation. New studies show the effects of EPO on immune system. Objective: In this study, the effects of pretreatment with recombinant human erythropoietin (rHuEPO) on the anti-human leukocyte antibody (anti-HLA) titer were determined. Methods: Three groups of rats were sensitized with human...

The pharmacokinetics of recombinant human erythropoietin (rHuEpo) administered intravenously has been investigated in a group of five patients with chronic renal failure who were dialysis-dependent. The half-life of circulating erythropoietin decreased from 7.9±OA hr (mean ±SO) at the beginning of treatment to 6.2±O.6 hr after 6 weeks and 5A±O.9 hr after 4 months of treatment. In spite of t...

Cardiovascular and renal diseases constitute two pathophysiological contexts of progressive fatal recognitions worldwide as priorities in terms health its entirety. Erythropoietin is a glycoprotein hormone which produces red blood cells, carry oxygen the blood. The objective was to know most prevalent modifiable risk factors found arterial hypertension, since this disease third cause death worl...
