Objectives: Hepatoma is a very serious disease in Korea and worldwide. Hepatitis B virus (HBV) has proved the most significant cause of hepatoma. We carried out this study to investigate the effect of Injinchunggan-tang (Yinchenqinggan -tang) on inhibiting cell proliferation and DNA synthesis in HepG2.2.15 cell lines and on inhibiting phosphorilation of oncogene (MAP kinase) in NIT /3T3-HEx cells. Methods: First we confinned the Hepatitis B virus producing ability of HepG2.2.15 cells. To investigate the anti-cancer effect of Injinchunggan-tang (Yinchenqinggan-tang), we did the NTS/PMS assay, [3H]-thymidine incorporation assay and transfection of pcDNA-X. We also measured the gene expression through western blotting. Results: Injinchunggan-tang (Yinchenqing gan tang) showed the suppressing effect of HepG2.2.l5 increase in the MTS/PMS assay and the inhibiting effect of DNA synthesis of HepG2.2.15 in the [3H] thymidine incorporation assay. Injinchunggan-tang (Yinchenqinggan-tang) also showed the inhibiting phosphorilation effect of MAP kinase in HBV -X genes. Conclusions: From the above Injinchunggan-tang (Yinchenqinggan-tang) is thought to have an anti-cancer effect on the hepatoma from HBV. It is suggested that further studies on this prescription would give us a better medicine with an anti-cancer effect.
