摘要:

目的 探究痘苗病毒致炎兔皮提取物(AGC)对大鼠脑缺血再灌注损伤的保护作用及机制。
方法 Sprague-Dawley大鼠61只分为假手术组(n = 11)、假手术给药组(n = 11)、模型组(n = 20)和模型给药组(n = 19)。模型组和模型给药组线栓法脑缺血1.5 h后恢复灌注。模型组和模型给药组各有2只造模不成功。再灌注3 h后,假手术给药组和模型给药组尾静脉每天注射AGC 20 U/kg,假手术组和模型组尾静脉注射等体积生理盐水。给药48 h后每组取4只大鼠Western blotting方法检测脑组织热休克蛋白(HSP70)、Bcl-2和Bax表达;给药7 d后,行抓握牵引实验;各组取4只大鼠,免疫组化法观察离子钙结合蛋白(Iba1)阳性和胶质纤维酸性蛋白(GFAP)阳性表达。
结果 与模型组相比,模型给药组抓握时间明显延长(P < 0.01),HSP70和Bcl-2表达明显升高( P < 0.01),Iba1阳性和GFAP阳性面积下降( P < 0.05)。
结论 AGC能促进脑缺血再灌注损伤大鼠运动功能恢复,可能与抑制细胞凋亡和神经炎症反应有关。

Abstract:

Objective To observe the effects of Analgecine (AGC) on middle cerebral artery ischemia-reperfusion injury in rats and its mechanism.
Methods A total of 61 Sprague-Dawley rats were divided into sham group (n = 11), sham-AGC group (n = 11), model group (n = 20) and model-AGC group (n = 19). The model group and the model-AGC group were occluded the middle cerebral arteries for 1.5 hours and reperfused (2 rats in each group unsuccessful). The sham-AGC group and the model-AGC group were injected AGC 20 U/kg through tail-vein, while the sham group and the model group were injected saline of same volume. Four rats in each group were tested heat shock proteins 70 (HSP70), Bcl-2 and Bax in brain with Western blotting 48 hours after injection. The other rats were assessed with Prehensile Traction Test seven days after injection, and then, four of each group were detected ionized calcium binding adapter molecule 1 (Iba1) and glial fibrillary acidic protein (GFAP) expression with immunohistochemistry.
Results The prehensile time increased in the model-AGC group compared with that of the model group (P < 0.01), with the increase of HSP70 and Bcl-2 ( P < 0.01) and decrease of Iba1 and GFAP expression ( P < 0.05).
Conclusion AGC may promote the recovery of motor function in rats with cerebral ischemia-reperfusion injury, which may associate with inhibiting cell apoptosis and neruoinflammatory response.
