摘要 To search for possible anti-tumor promoters, we carried out a primary screening of fourteen kampo prescriptions utilizing their possible inhibitory effects on the Epstein-Barr virus early antigen (EBV-EA) activation which is induced by 12-O-tetradecanoylphorbol-13-acetate (TPA). In these prescriptions, shouseiryu-to exhibited the most significant inhibitory effect on the EBV-EA activation. Furthermore, two-stage carcinogenesis of mouse skin tumors induced by 7,12-dimethylbenz[a]anthracene (DMBA) and TPA, and mouse pulmonary tumors induced by 4-nitroquinoline-N-oxide (4NQO) and glycerol were strongly inhibited by shouseiryu-to.
