Objective: To observe the effects of the extract of Syringa on the secration of HBsAg and HBeAg in HepG2.2.15 cells. Methods: Enzyme linked immunosorbent assay (ELISA) was used to detect the secration of HBsAg and HBeAg and suppressive rate was used to represent the values. Results:The extract of Syringa might suppress the secration of HBsAg and HBeAg in dose dependent and time dependent manners. Conclusion:The suppressive effect of the extract of Syringa on the secration of HBsAg and HBeAg suggests that ...
