Abstract:
Objective To observe the effect of arsenic trioxide on the apoptosis of synovium and IL-l, TNF-? in CIA rat. Methods Seventy-two rats were divided into normal control, model, and As2O3 treatment groups. The experimental models of collagen induced arthritis rats were used as the experimental moldels. The knees′ synovium, cartilage and bone tissue of the rat were taken out, then observed with light microscope and electron microscope and apoptosis were measured by TUNEL after the 15th day of treatment. Meanwhile the level of IL-1 and TNF-? were measured with ELISA kit. Results The pathological injury were improved and the apoptosis of synoviocytes were increased in the As2O3 treatment group, compared with the model group. IL-1 and TNF-? levels were decreased in the arsenic trioxide treatment groups, especially in the Ⅴ and Ⅵ groups (P
