title: Inhibition of collagen production by traditional Chinese herbal medicine in scleroderma fibroblast cultures.
abstract: The in vitro effect of one traditional Chinese herbal medicine (Japanese name: "Keishi-bukuryo-gan"), which has been empirically used in scleroderma patients in China and Japan, on collagen production in fibroblast cultures was studied. Fibroblasts from 3 scleroderma patients and 2 normal controls were incubated with various concentrations of "Keishi-bukuryo-gan" and collagen production was then determined by a radiochemical method. "Keishi-bukuryo-gan" significantly and selectively inhibited collagen synthesis in a dose-dependent manner, with a tendency of a stronger effect on scleroderma fibroblasts than control cells. The results may explain the clinical usefulness of this medicine, and it may become a promising new agent for the treatment of scleroderma.
