Abstract: | To analyze the anti-arthritic effects of QFGJS (a pharmaceutical preparation from herbs) on rheumatoid arthritis, adjuvant-induced arthritis (AIA) was established in male SD rats, and two administration protocols, i.e., oral treatment with different doses of QFGJS on the day of arthritis induction or on the day when visible clinical signs of arthritis occurred, were initiated and continued until day 30. Treatments with QFGJS using both administration protocols significantly suppressed the incidence and severity of arthritis in a dose-dependent manner, showing dramatic reduction of paw swelling and ESR throughout the disease progression of AIA. Radiological and histopathological examinations showed markedly decreased tissue and bone destruction of ankle joints in the QFGJS-treated rats. The serum levels of TNF-alpha, IL-1beta, and IL-6 were significantly decreased in the QFGJS-treated rats. QFGJS demonstrates pronounced anti-arthritic effects on AIA, indicating that this herbal preparation would be a potent candidate as a novel botanical drug for further investigation. |
