摘要
目的观察线粒体钙单向转运体在大鼠脑缺血/再灌注(I/R)损伤中的作用及其机制。方法将40只雄性Wistar大鼠随机分为4组:A组(假手术组)、B组(脑缺血再灌注组)、C组(脑缺血再灌注+钌红组)、D组(脑缺血再灌注+精胺组),采用线栓法建立大鼠大脑中动脉闭塞(MCAO)模型,各组在脑缺血2h后进行再灌注,再灌注24h后观察各组大鼠神经功能评分,检测各组血清脂质过氧化产物丙二醛(malondial-dehyde,MDA)的含量、血清乳酸脱氢酶(LDH)、超氧化物歧化酶(SOD)的活性,免疫组化检测皮质区Caspase-3阳性细胞数的变化。结果 B、C、D组神经功能评分升高,血清MDA的含量以及LDH活性显著高于A组,SOD活性与A组相比显著降低,caspases-3表达细胞与A组相比明显增多。C组能明显改善上述结果,而D组相反。结论抑制线粒体钙单向转运体可以明显减轻脑缺血再灌注损伤,其机制可能与减少氧自由基产生、维护线粒体功能有关。
