Chronic renal failure (CRF) is a rapidly growing global health problem and it causes anaemia and cognitive impairment. Recombinant Human erythropoietin (rHu-Epo) has been a promising role in the management of anaemia in CRF subjects and it is well documented. It also shown as a remarkable neuroprotection in both cell cultures and in animal models. Creatine kinase (CK) plays a key role in energy metabolism and its activity found in cytoplasm of several human tissues; major sources of CK include skeletal muscle, myocardium and brain. Studies show brain energy metabolism is key to neuronal cell function and cognitive health. The aim of this study is to investigate the impact of rHu-Epo on CRF induced changes in CK system in serum and brain regions of experimental animals and to test its significance in neurobehavioral changes. Experimental design is divided into two phases to find out the variation between simultaneous and post rHu-Epo Treatment in CRF induced male wistar rats. At the end of 40 days, animals were sacrificed uniformly. In both phases, CK level in serum and selected brain regions such as cerebellum, cerebral cortex and hippocampus were determined by spectrophotometric method and hematological parameters (RBC, Hb, PCV, MCV, MCH, MCHC) were also determined. In results, decreased creatine kinase activity in brain regions and its increased level in serum observed in CRF induced animals. Neurobehavioral changes and alterations in hematological parameters were also seen in CRF induced animals. Supplementation of rHu-Epo in both simultaneous and post treatment group reversed the CRF induced changes including neurobehavioral alterations, significantly. In this study, the protective role of Epo supplementation on CRF induced changes in CK system in both brain and serum and its correlation with neurobehavioral changes were seen along with its antianemic effect.
