摘要:

给Wistar大鼠灌胃0.180g/mL的补肾中药,淫羊藿、菟丝子、肉苁蓉,0.04 mg/mL的单胺氧化酶B抑制剂司来吉兰或蒸馏水连续14 d,制备含药血清或空白血清。用15%各含药血清培养液培养对数生长期的MES23.5多巴胺能神经细胞24h后,加入含100μM H2O2培养液培养3h。MTT结果显示,淫羊藿、菟丝子、肉苁蓉及司来吉兰含药血清均能提高H2O2损伤的MES23.5细胞的存活率。流式细胞仪检测结果显示,淫羊藿、菟丝子、肉苁蓉及司来吉兰含药血清均能抑制H2O2损伤的MES23.5细胞凋亡相关蛋白FasL和Caspase-3的表达,促进抑凋亡蛋白Bcl-2的表达,而对Fas的表达无明显影响。ELISA结果显示,肉苁蓉和淫羊藿含药血清可提高H2O2损伤的MES23.5细胞神经生长因子、脑源性神经营养因子、胶质细胞源性生长因子的表达,而菟丝子含药血清仅能提高细胞脑源性神经营养因子的表达;司来吉兰含药血清对上述神经营养因子的表达均无明显促进作用。作者认为,这项研究结果证实了补肾中药可调节MES23.5细胞凋亡因子及神经营养因子的表达,产生保护神经细胞的效应。

Abstract:

Wistar rats were intragastrically perfused with Chinese medicines used for tonifying the kidney. These included 0.180 g/mL of Herba Epimedii (Epimedium), Semen Cuscutae (Dodder Seed), or Herba Cistanches (Desertliving Cistanche), 0.04 mg/mL monoamine oxidase-B inhibitor selegiline, or distilled water for 14 consecutive days to prepare drug-containing serum or blank serum. MES23.5 cells in the logarithmic phase were cultured in media supplemented with 15% drug-containing serum for 24 hours, followed by incubation in culture solution containing 100 μmol/L H2O2 for 3 hours. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and flow cytometry results showed that all drug-containing serums improved the survival rate of H2O2-injured MES23.5 cells, inhibited pro-apoptotic FasL and caspase-3 expression, promoted anti-apoptotic Bcl-2 expression. However, drug-containing serums had little influence on Fas expression in H2O2-injured MES23.5 cells. Enzyme-linked immunosorbent assay results showed that serum containing Herba Cistanches or Herba Epimedii increased the expression of nerve growth factor, brain-derived neurotrophic factor, and glial cell line-derived neurotrophic factor in injured MES23.5 cells; serum containing Semen Cuscutae only increased brain-derived neurotrophic factor expres-sion; while expression of the above neurotrophic factors remained the same in cells treated with serum containing selegiline. These findings indicate that Chinese medicines used to tonify the kid-ney can protect nerve cells by regulating the expression of apoptosis-related factors and neurotrophic factors in MES23.5 cells.
