摘要 目的:研究中药独活对Aβ1-40所致阿尔茨海默症模型鼠脑组织中炎性进程的抑制作用。方法:以Aβ1-40海马内注射制成阿尔茨海默症模型,分别给予中药祛湿药独活、活血化瘀药丹参及非甾类抗炎药吲哚美辛灌胃。4周后处死动物。采用免疫组化方法,测得不同组别的大鼠脑内IL-1、IL-6、NF-κB蛋白的表达差异。结果:给药后模型组与假手术组比较IL-1、NF-κB及IL-6有较高水平的表达,说明大鼠脑内注射Aβ蛋白使大鼠脑中上述细胞因子的分泌明显增加,西药组、独活组、丹参组与假手术组、模型组比较,差异显著(P<0.05),提示三药均能对Aβ大鼠脑中上述指标的表达有很好的抑制作用,但不如假手术组,(丹参组NF-κB的表达同模型组)。丹参组、独活组及西药组比较,差异不显著(P>0.05),说明在中药对脑内炎性反应具有一定的抑制作用,疗效同非甾类抗炎药吲哚美辛。结论:祛风胜湿药之独活可通过抑制Aβ大鼠脑中IL-1、IL-6、NF-κB等细胞因子的表达,从而减轻Aβ大鼠脑中炎性反应。
