iron overload is a serious clinical condition which can be largely prevented by the use of iron-specific chelating agents. in this study, the synthesis and determination of partition coefficients (kpart) of a range of n-alkyl hydroxypyridinones, as orally active iron chelators, are described. synthesis of n-aryl hydroxypyridinones was achieved via a single step synthetic pathway. in this method...

background: patients with transfusional iron overload have depended on iron chelation therapy and improving chelation regimens have been of the highest priority. the aim of this study was to compare effect of combined versus monotherapy with deferoxamine (dfo) and deferiprone (dfp) in iron overloaded beta thalassemia (bt) major patients materials and methods we studied 36 bt major patients (mea...

forty two small ruminants, 26 (61.90%) sheep and 16 (38.10%) goats were treated for rumen acidosis. 19 (45.24%), 12 (28.57%), 6 (14.29%) and 5 (11.90%) animals had eaten apple, cooked rice (wazwan left over) turnip and chapatti respectively and manifested clinical form of ruminal acidosis with, 2.86%; (n=18) as mild (rumen fluid ph=6.32 ±0.09316), 38.09%;(n=16)moderate (rumen fluid ph=5.71 ±0.0...

isolated rat hepatocytes in culture were incubated with different concentrations of iron-sorbitol (50, 100, 150, and 200 µm) to assess the changes in reactive oxygen species (ros) and lipid peroxidation leading to apoptotic hepatocyte cell death. the viability of hepatocytes was declined depending on the iron concentration. one hour incubation of the cells with 100 µm iron resulted in decreased...

background: sickle-cell anemia is characterized by defective hemoglobin synthesis with production of sickle hemoglobin. sickle red blood cells become deformed and rigid with difficulty to pass through narrow capillaries and frequent clotting and thrombosis leading to repetitive vascular occlusions and progressive organ damage. we conducted this work to study some adrenal functions using acth st...
