title: [Effects of tripchlorolide (T4) of Tripterygium Wilfordii Hook on the production of immunoglobulins by peripheral blood mononuclear cells and by synovial cells of rheumatoid arthritis patients in vitro].
abstract: Tripchlorolide(T4) is an active ingredient recently isolated from Tripterygium Wilfordii Hook. The in vitro effects of T4 on the peripheral blood mononuclear cells(PBMC) of healthy persons(n = 10), the digested single synovium cells(DSSC) (n = 3) and PBMC(n = 6) from RA patients on production of immunoglobulins (Ig) were studied using Elisa method. The results showed that T4 at concentrations from 5 ng.ml-1 to 35 ng.ml-1 significantly reduced the production of Ig by PWM-stimulated PBMC of healthy persons in a dose dependent manner. At concentration of 25 ng.ml-1, T4 also reduced the Ig secretion of RA-PBMC and DSSC. It is hoped that T4 would be an encouraging new drug of herbal nature for the treatment of RA.
