At the endpoint, the thymus, spleen and uterus were weighed separately; the femoral dry weight, bone-calcium, phosphor, magnesium and hydroxyproline contents of femoral were measured; the histomorphological features of bone were observed and the biochemical indexes in serum (Ca, P, ALP, TRAP, E2, BGP) were determined after the mice were given SAR at the dose of 10, 30, 90 mgkg^(-1) respectively, and were compared with the model group, the normal control and the positive control. RESULTS: The osteoporosis of high turnover type was formed with feeding retinoic acid to experimental mice.
