Abstract:
Aim To investigate the effects of red yeast rice capsules containing coenzyme Q10 on femur with an animal model of osteoporosis, which was induced by OVX with D-galactose in rats, and the results were compared with those obtained from diethylstilbestrol. Methods Three-month old female Sprague-Dawley rats were randomly divided into sham group ( CON ) , ovariectomized group ( OVX ) , model group ( MOD ) , diethylstilbestrol group( DES) , and red yeast rice cap-sule group( RYR) . After 60 days, the left femurs were collected for Ca, P and hyp measurement, while the right femurs were performed with three-point bending test and micro-CT evaluation, respectively. Results Compared with CON group, MOD group had a signifi-cant increase in body weight, Tb. Sp, SMI and signifi-cant decrease in maximum load, stiffness, maximum strength, break strength, elastic modulus, Ca, P, Hyp contents and indicators of BV/TV, Tb. N, BMD, Conn-Dens. On the other hand, compared with MOD group, RYR group had a lower body weight and all bone biomechanics indexes were increased without sta-tistically significant difference. At the same time, the content of Ca, P and indicators of BV/TV, Tb. N, Tb. Th, BMD, Conn-Dens increased significantly;yet Tb. Sp decreased significantly. In DES group, the results of indicators were consistent with those for RYR group. In addition, compared with DES group, in RYR group body weight decreased significantly;the content of Ca, P and indicators of BV/TV, Tb. N, Tb. Th, Conn-Dens were significantly higher, and Tb. Sp, SMI were significantly lower. Conclusions Significant bone loss and deteriorated mechanical properties of femur can be observed in animal model of osteoporosis induced by OVX combined with D-galactose. Red yeast rice cap-sules containing coenzyme Q10 show effective prevention effects. Furthermore, red yeast rice capsules(0. 5 tab-let·kg-1 ) have better effect on increasing the number of trabecular bone than diethylstilbestrol ( 30 μg · kg-1 ) does.
