摘要 目的:观察川芎嗪对大鼠急性脊髓损伤(SCI)后神经细胞的早期凋亡的影响,进一步认识其在脊髓损伤后细胞凋亡中的作用机制。方法:采用改良Allen’s重物打击法建立大鼠急性脊髓损伤模型,120只成年SD大鼠,随机分成4组:正常组(A组)、模型组(B组)、甲基强的松龙组(C组)及川芎嗪组(D组),每组各30只,造模后B组、C组和D组分别按时注射同体积的生理盐水、甲基强的松龙及川芎嗪注射液。损伤后各时间采用BBB法行神经功能评分,流式细胞术观察细胞凋亡情况,透射电镜观察细胞形态学变化情况。结果:D组伤后各时间点细胞凋亡与C组伤后各时间点细胞凋亡比较,差异无统计学意义(P>0.05),但D组和C组与模型组比较差异有统计学意义(P<0.05)。结论:早期使用川芎嗪能减轻大鼠急性脊髓损伤后的神经细胞凋亡,对大鼠急性脊髓损伤有一定神经保护作用,主要机制可能和抑制细胞凋亡的"级联反应"有关。
