摘    要:目的观察曲美他嗪(TMZ)对大鼠局灶性脑缺血后神经细胞Caspase-3 mRNA、Bcl-2 mRNA表达的影响。方法成年健康Wistar大鼠45只,随机分为假手术对照组(n=5)、脑缺血再灌注组(n=20)、TMZ预处理组(n=20)。应用线栓法建立大脑中动脉闭塞再灌注模型。采用原位杂交方法检测脑组织Caspase-3 mRNA、Bcl-2m RNA表达的变化。结果Bcl-2 mRNA在缺血再灌注3h表达增强(P〈0.05),6h显著增强(P〈0.01),24h减弱(P〈0.05),48h消失(P〉0.05)。TMZ组的Bcl-2 mRNA表达量多于缺血再灌注组,差异有统计学意义(P〈0.05)。Caspase-3 mRNA在再灌注3h表达增强(P〈0.05),6h显著增强(P〈0.01),24h更加明显(P〈0.01),48h减弱(P〈0.05)。TMZ组的Caspase-3 mRNA表达量显著少于缺血再灌注组,差异有统计学意义(P〈0.05)。结论TMZ可能通过诱导Bcl-2的表达和抑制Caspase-3的生成而发挥抗凋亡作用。

关 键 词:曲美他嗪  脑缺血再灌注损伤  Bcl-2mRNA  Caspase-3mRNA

Abstract:Objectives To observe trimetazidine (TMZ) influence of the Bcl-2 mRNA, Caspase-3 mRNA expression in the focal cerebral ischemia and reperfusion tissue. Methods To make use of the focal cerebral ischemia and reperfusion model induced by a suture method which preferred by Zea Lon- ga in rats,45 adult Wistar rats randomly were allocated to the sham-operation group, ischemia and reper- fusion group and TMZ pretreatment group. Hybridization in situ technique was used to investigate the Bcl-2 mRNA, Caspase-3 mRNA...
