ABSTRACT: Erythropoietin, or EPO, is a glycoprotein hormone that controls erythropoiesis, or red blood cell production. It is a cytokine for erythrocyte (red blood cell) precursors in the bone marrow. Also called hematopoietin or hemopoietin, it is produced by the peritubular capillary endothelial cells in the kidney, and is the hormone that regulates red blood cell production. The existence of a hormone that controls RBC production was first suggested by the experiments of Paul Carnot in 1906, who created anemic rabbits and then transfused their serum into recipient rabbits. EPO is produced by peritubular cells in the adult kidney, and in hepatocytes in the fetus. In adults, a small amount is also produced by the liver. The rate of Epo synthesis and secretion depends on local oxygen concentrations; hypoxia is the main stimulus for Epo production. Although the use of erythropoietin has been studied in critically ill patients, erythropoietin has not been shown to be effective in ...

ABSTRACT A simple, rapid and accurate high performance liquid chromatography method is described for determination of carbocisteine from pharmaceutical formulation. The separation of drug was achieved on (Amino Propyl Silane) APS-2 hypersil (250 X 4.6 mm) 5μ column. The mobile phase consisted a mixture of buffer and methanol (65:35 v/v). The buffer was a mixture of 0.02 M potassium dihydrogen phosphate monobasic and 0.01 M1-hexane sulphonic acid sodium salt anhydrous. The detection was carried out at wavelength 210 nm. Buffer containing 0.02 M potassium dihydrogen phosphate monobasic and 0.01 M1-hexane sulphonic acid sodium salt anhydrous used as a diluent.
