摘要
Abstract
[ Objective ] To explore the neuroprotection mechanism of erythropoietin (EPO). [Methods ] Transient global cerebral ischemia model was made by 4-VO technique. Male SPraque-Dawley rats were as the experimental objects, which were randomly separated into 3 of groups including Sham, Saline control and EPO-Pretreatment. At 3hours before global cerebral ischemia, saline or EPO was respectively injected into the lateral ventricle of rat, with help of stereotaxic coordinates, upon the designed conditions. The Sham rats were only performed the incision on cervix but without any treatment on the arteries. Observed if expression of cytochrome c (CytC) was related to bcl-xl at 24 hours after the model operation, in hippocampal CA1 subregion. [Results] Expression of CytC was not related to bcl-xl in Sham and Saline control group, but was evidently related to bcl-xl in EPO-Pretreatment(r = 0.818;P =0.013). [Conclusions] Pretreatment of EPO could inhibit CytC releasing into cytoplasm in hippocampal CA1 subregion in the modeled rat, which could relate to promoted expression of bcl-xl.关键词
