We have found that Juzen-taiho-to has a preventive effect on endometrial carcinogenesis in mice (Carcinogenesis 22 (2001) 587). In the present study, the constituents of Juzen-taiho-to responsible for this effect were explored using a short-term experiment. Thirty female ICR mice were divided into five groups: Group 1 was given a diet containing 0.2% of Juzen-taiho-to and 5ppm estradiol-17beta (E(2)); Group 2 was given a diet containing Shimotsu-to (0.07%) and E(2) (5ppm); Group 3 received Shikunshi-to (0.08%) and E(2) (5ppm) in the diet; Group 4 was given 5ppm E(2) in the diet; and Group 5 served as a control. Exposure of Juzen-taiho-to or Shimotsu-to decreased E(2)-stimulated expression of estrogen-related gene c-fos mRNA (P<0.05), and the cytokines interleukin-1alpha mRNA and tumor necrosis factor alpha mRNA P<0.01). A similar trend was not found upon treatment with Shikunshi-to. These findings suggest that Shimotsu-to is responsible for the inhibitory effects of Juzen-taiho-to on the estrogen-related endometrial carcinogenesis in mice.
