ABSTRACT
[Objective] To observe the effects of Tongbiling (TBL) prescription in counteracting cartilage destruction in rats with rheumatoid arthritis (RA). [Methods] Collagen-induced arthritis (CIA) rat models were established to observe the therapeutic effects of TBL. After a short-term treatment, expressions of tumor necrosis factor (TNF - a) and transforming growth factor (TGF- P) in cartilage tissue of model group, methotrenxate (MTX) tablets group and Radix Tripterygii Wilfordii (RTW) preparation group were examined by immunohistochemical semi-quantitative assessment method. [ Results ] The number of chondrocytes with positive TNF - a expression was lower and the chondrocytes were stained lighter in normal group than those in model group and low-dose MTX group ( P
