Introduction

 Erythropoietin (EPO) is reported to have a minimizing effect on the ischemic condition, but the detailed association between EPO and the ischemic upshot is still not clearly understood. We aimed to evaluate the effect of EPO on inflammatory response and ischemic brain damage after carotid artery clamp in rats.

Methods

 In this experimental, animal trial study, which was conducted at the Animal Facility and laboratory at Tabriz University of Medical Sciences, 50 adult male Wistar rats with (250 to 300 g) were randomly allocated to intervention and control groups. The intervention and control groups were administered intraperitoneally with equal volumes of EPO (5000 U/kg) and normal saline, respectively. Both groups had common carotid arteries clamped for 20 minutes. Using the Nissl staining technique, the slides of brain ischemic areas were observed and the rate of ischemic injury in both groups was determined. The blood level of inflammatory cytokines was also measured.

Results

 The levels of inflammatory markers including creatine phosphokinase (CPK), interleukin (IL)-6, IL-1B and tumor necrosis factor alpha (TNF)-α in the intervention group were significantly lower than that of control group. Mean percentage of the ischemic area in the intervention group with an amount of 4.30±2.15%, was significantly lower than that of control group (11.20±2.35%, P=0.023).

Conclusion

 Findings of this study showed that the injection of EPO before carotid clamping is effective in preventing cerebral ischemic injury in rats.
