Abstract:
Tripchlorolide(T
4) is an active ingredient recently isolated from
Tripterygium Wilfordii Hook. The
in vitro effects of T
4 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 T
4 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, T
4 also reduced the Ig secretion of RA-PBMC and DSSC. It is hoped that T
4 would be an encouraging new drug of herbal nature for the treatment of RA.
