摘要: 目的:探讨他米巴罗汀(Am80)对大鼠脑缺血再灌注损伤(CIR)的作用。方法:将大鼠随机分为:假手术组(sham)、模型组(I/R)和他米巴罗汀干预组(Am80,灌胃给予Am80 6 mg/kg)。采用线栓法建立大脑中动脉栓塞(MCAO)模型。术后24 h断头取脑,在处死前采用双盲法进行神经行为学评分;TTC染色测定脑梗死体积;Western blot和RT-qPCR法分别检测RARα、Bcl-2和Bax蛋白及mRNA的表达。结果:Am80可显著改善MCAO大鼠神经功能缺损,有效的降低脑梗死体积(P<0.01),上调RARα和Bcl-2表达(P<0.01),降低Bax的表达(P<0.01)。结论:他米巴罗汀对脑缺血再灌注损伤大鼠有保护作用,其作用可能与抗凋亡有关。

Abstract: Objective To investigate the effect of tamibarotene(Am80)on cerebral ischemia reperfusion injury.Methods Rats were randomly divided into sham operation group (Sham), model group (I/R) and tamibarotene intervention group (Am80, intragastric administration of Am80 6mg/kg). The middle cerebral artery occlusion (MCAO) was established by using suture method. At 24 h after reperfusion, the brain was removed. And the neurological behavioral score was assessed by double blind method. The cerebral infarction volume was measured by TTC staining. The proteins of RARα, Bcl-2, Bax and mRNA were examined by Western blot and RT-qPCR, respectively. Results Am80 significantly improved the neurological deficits of MCAO rats and effectively reduced the infarct volume. And upregulated the level of RARα and Bcl-2, decreased the expression of Bax. Conclusions Am80 has a protective effect on cerebral ischemia-reperfusion in rats, and its effect may be related to anti-apoptosis.
