Forty rats were divided into 5 groups. Adjuvant arthritis (AA) models were made with complete freund's adjuvant (CFA) in groups Ⅰ-Ⅳ. Each of which was treated with sodium carboxyl methyl cellulose, TW, prednisone and cyclophosphamide respecrively.The untreated rats allocated to group,V served as normal. controls. The swelling of AA markedly subsided in groups Ⅱ,Ⅲ and Ⅳ as compasred with group I (P<0.01). whereas no significant differences were noted among groups Ⅱ, Ⅲ and Ⅳ(P>0.05).The obviously increased plasma corticosterone levels and decreased adrenal ascorbic acid levels were observed in group Ⅱ,whereas decreased plasma corticosterone levels and inereased adrenal ascorbic acid levels were noted in group Ⅲ.There was a striking comtrast between groups Ⅱand Ⅲ. The morphological changes of adrenal glands under light microseope revealed hypertrophic adrenal cortices in group Ⅱ,and atrophic adrenal cortices in group Ⅲ.The above findings snggest that that the effect promoting production of corticosterods may be one of mechanism by which TW can effectively treating autoimmune diseases.展开更多

Rats were divided into SMF- treated AA rats, non-SMF treated AA rats and control rats. Following SMF stimulation, we measured blood flow volume in the paw and then reactive speed response to thermal stimulation. The AA groups exhibited significantly lower blood volume and reactivity to thermal stimulation compared to the control group. Compared to non-SMF, SMF exhibited increased blood flow volume in both the tail and paw, along with an increased reactive speed response to thermal stimulation. Our findings suggest that an improved of blood flow and reactive speed response, induced by SMF, appears to be effective for the relief of pain induced by chronic inflammation.展开更多
