Abstract:
This study sought to investigate the in vivo antiviral effect of amantadine (AM) and biphenyl dimethyl dicarboxylate (DDB) on hepatitis B virus (HBV) in HBV replication mice. HBV replication-competent plasmid was transferred into male BALB/c mice by using hydrodynamics-based in vivo transfection procedure to develop HBV replication mouse model. The model mice were matched by body weigh, age and serum levels of hepatitis B e antigen (HBeAg) and were divided into four groups: AM group, DDB group, AM+DDB group and NS group, with the last one as control, and the mice of each group were administered corresponding agent orally twice a day, in a medication course lasting 3 d. On the third day, the mice were sacrificed 4-6 h after the last oral intake. HBV DNA replication intermediates in liver were analyzed by Southern blot hybridization. The serum hepatitis B surface antigen (HBsAg) and HBeAg were detected by enzyme linked immunosorbent assay (ELISA). Compared to the animals in the control group, HBV DNA replication intermediates in liver and HBsAg and HBeAg in serum from the AM and AM plus DDB group of mice decreased, and there was no difference between these two groups of mice. The levels of HBV DNA intermediate from liver and the serum HBsAg and HBeAg between the control and DDB group, however, were not obviously different. In conclusion, the inhibition effect of AM on HBV was detected, but treatment with DDB for 3 days did not influence the viral replication and expression of HBV in the HBV replication mice.
