Pulp reactions were obvious during 3 days after lased. Alkaline phosphatase examination: After fixed, decalcified and selected, all experimented teeth were stained with the Ca-Co method in order to examine the alkaline phosphatase activity in dental pulp cells.

碱性磷酸酶的检测：实验牙在丙酮中固定1 d，再置入复合酸中脱钙，冰冻切片后，进行钙-钴法染色以显示牙髓细胞中碱性磷酸酶活性，根据米德冷图象分析系统测定切片的灰度值，进行统计学分析。

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. Compared with the model group, the lessening of femoral dry weight, the short femoral transverse diameter, the decrease of bone mineral and bone-hydroxyproline of SAR groups were improved.
