ABSTRACT

Objective To observe the effect of Duanteng Yimu decoction (DYD) on bone turnover markers of C-terminal telopeptide of type Ⅰ collagen (CTX-Ⅰ) and N-terminal propeptide of type Ⅰ procollagen ( PⅠNP) of adjuvant-induced arthritis (AA) rats. Methods Seventy-two SD rats were divided into 9 groups, and complete Freund's adjuvant was injected into the rats to establish adjuvant-induced arthritis rat model. After medication for 36 days, the pedal swelling, the serum levels of CTX-Ⅰand PⅠNP, and ankle X-ray photographic scores were observed. Results The pedal swelling degrees and ankle X-ray scores in medication groups were lower than those in the model group ( P0.05). The CTX-Ⅰlevel in low-dose DYD group was decreased (P<0.05). Conclusion Caulis Celastri has two-way effects on CTX-Ⅰlevel of female AA rats, and its side effects can be reduced by Radix Dipsaci and Herba Leonuri, but their antagonism effect will disappear with the increase of the dose of Caulis Celastri.
