培补肝肾复方中药对PC12细胞损伤模型的保护作用

Protective effect of Prescription for Nourishing Liver- Kidney on Injured Cultured PC12 Cell in Vitro

目的探讨培补肝肾复方对1-甲基-4-苯基吡啶离子(1-methyl-4-phenylpyridinium,MPP+)所致PC12细胞损伤模型的保护作用。方法采用血清药理学方法,制备中药含药血清,以肾上腺嗜铬细胞瘤克隆化细胞株PC12细胞为材料,利用MPP+建立经神经生长因子(NGF)诱导前后的PC12细胞的损伤模型,观察不同给药剂量的培补肝肾中药血清对PC12细胞的作用。结果形态学检查发现等效剂量培补肝肾中药复方血清可显著提高PC12细胞的存活数,减低细胞损伤程度。结论培补肝肾复方中药血清可对抗MPP+引起的细胞损伤,对体外培养的PC12细胞具有保护作用。

Objective To investigate the protective effects of prescription for nourishing liver- kidney (PNLK) on PC12 cell injyred by 1- methyl- 4- phenylpyridinium (MPP+ ).Methods The rabbit serum contained PNLK was preparing by the method of sero- pharmacology.PC12 cell was cloned from pheochromocytoma of adrenal medulla and the MPP+ injured models were induced by nerve growth factor.The effect of serum containing PNLK on PC12 cell from MPP+ injured models was assayed by morphological, MTT staining and LDH measurement.Results The equivalent dosage of the serum of PNLK possessed obvious protective effects on PC12 cell,increased the number of survival cells and relieved the injury significantly.Conclusion Serum of PNLK can counteract the injuryof PC12 cell induced by MPP+ and has protective effect on PC12 cell in vitro.
