GST, an extract from 16 herbs, has been formulated and prescribed for the treatment of human rheumatoid arthritis(hRA) for many years. The present study was done to investigate whether GST has suppressive effects on activation of fibroblast-like sinoviocytes isolated from an RA patient. In tumor necrosis factor-a(TNF-a)/interleukin-1b(IL-1b) treated human sinoviocytes, The mRNA expression of molecular indicators related to pathologic changes of the sinoviocytes were examined using quantitative real-time PCR. The treatment of GST($100\;{\mu}g/ml$) suppressed the expression of proinflammatory cytokines and chemokines such as TNF-a, IL-1b, IL-6 and IL-8 compared with the control. The mRNA level of intracellular adhesion molecule-1(ICAM-1) which is known to increase in the activated sinoviocytes of RA patients, was slightly decreased by GST. The expression of NOS-II was considerably reduced, which was accompanied by a decrease in the production of nitric oxide(NO). In addition, GST considerably increased the mRNA levels of tissue inhibitors of matrix metalloproteinase-1(TIMP-1), while those of matrix metalloproteinase-3(MMP-3) were decreased. Taken together, these data suggested that GST might suppress the activation of sinoviocytes in hRA.

Based on traditional medicine theories, GC, an extract from 5 herbs, has been formulated and prescribed for the treatment of human rheumatoid arthritis(hRA) for many years. The present studies was done to investigate whether GC has inhibitory effects on activation of fibroblast-like sinoviocytes isolated from a RA patient. In tumor necrosis factor-${\alpha}(TNF-{\alpha}$)/ interleukin-IL-$1{\beta}$(IL-$1{\beta}$) treated human sinoviocytes, the mRNA expression of molecular indicators related to pathologic changes of the sinoviocytes were examined using quantitative real-time PCR. The treatment of GC($10{\mu}g/ml$) significantly suppressed the expression of proinflammatory cytokines and chemokines such as $TNF-{\alpha}$, IL-6 and IL-8 compared with the control, but not $IL-1{\beta}$, The mRNA level of intracellular adhesion molecule-1 (ICAM-1) which is known to increase in the activated sinoviocytes of RA patients, was slightly decreased by GC. The expression of NOS-II was considerably reduced, which was accompanied by a decrease in the production of nitric oxide(NO). Furthermore, GC dramatically raised the mRNA levels of tissue inhibitors of matrix metalloproteinase-1 (TIMP-1), while those of matrix metalloproteinase-3 were significantly lowered. Taken together, these data suggested that GC might suppress the activation of sinoviocytes in hRA.
