紫丁香叶提取物及干扰素、肝炎灵抗乙型肝炎的比较研究

Comparative studies on the resistance of hepatitis B by Syringa extract,IFN and ganyanling in HepG2.2.15 cells

目的 :探讨紫丁香叶提取物对HepG2 .2 .15细胞存活率及其分泌HBeAg和HBsAg的影响 ,并与干扰素和肝炎灵相比较。方法 :采用3 H TdR掺入法检测HepG2 .2 .15细胞的存活率。采用ELISA检测 3种药物作用后HepG2 .2 .15细胞培养上清中HBeAg和HbsAg水平的变化 (以抑制率来表示 )。 结果 :①随着浓度的增加 ,各药对细胞的存活率均显示抑制作用 ,肝炎灵和干扰素对HepG2 .2 .15细胞存活的抑制率明显大于紫丁香叶提取物。②各药对HepG2 .2 .15细胞分泌HBeAg和HBsAg的抑制率 ,呈剂量依赖性。紫丁香叶提取物的抑制率介于干扰素和肝炎灵之间。结论 :紫丁香叶提取物是一种高效低毒的药物 。

AIM: To explore the effects of Syringa extract, IFN and ganyanling on the the survival rate of HepG2.2.15 cells and the secretion of HBsAg and HBeAg by HepG2.2.15 cells. METHODS: 3 H TdR incorporation and ELISA were used to detect respectively the survival rate of HepG2.2.15 cells and levels of HBsAg and HBeAg in culture supernatant of HepG2.2.15 cells after stimulation with 3 drugs. RESULTS: ①All of the three drugs decreased the survival rate of HepG2.2.15 cells to the various extent with the increase of doses. The effect of the Syringa extract was between those of IFN and ganyanling. ②All of the three drugs might suppress the secration of HBsAg and HbeAg by HepG2.2.15 cells in dose dependent manner, while the the effect of the syringa extract was between those of IFN and ganyanling. CONCLUSION: The syringa extract is an effective and low toxic anti hepatitis B drug.
