摘要 目的研究粗糠柴毒素对抗心肌缺血-再灌注损伤的作用。方法结扎雄性SD大鼠心脏冠状动脉左前降支40 min造成心肌缺血,剪断结扎线进行120 min再灌注,以此构建心肌缺血-再灌注模型。实验组大鼠缺血处理前给予1μmol/L粗糠柴毒素处理,对照组予生理盐水处理。抽取血液检测血清乳酸脱氢酶(LDH)及肌酸激酶(CK-MB)活性。随后取出心脏并取样,将细胞裂解并离心,对提取物进行Western印迹测定,其中乙醛脱氢酶(ALDH)2磷酸化比例。结果实验组LDH活性(4 079.6±88.3)U/L,对照组(5 703.7±451.9)U/L。实验组CK-MB活性(3 228.5±257.4)U/L,对照组(4 433.4±319.9)U/L。实验组磷酸化ALDH2占总ALDH2比例(0.340±0.032),对照组(0.101±0.037)。两组各指标均存在显著差异(均P<0.05)。结论粗糠柴毒素可显著提升缺血-再灌注心肌的ALDH2磷酸化水平并降低血清LDH和CK-MB水平,诱导心脏保护。ALDH2激活可能参与了粗糠柴毒素的心脏保护作用。
