摘要
目的观察骨松宝胶囊的抗骨质疏松作用。方法采用维甲酸70mg/kg连续ig14d造成大鼠实验性骨质疏松,测定实验组和模型组大鼠的骨形态学计量指标、血液生化学指标及每日尿中钙、磷排出量的影响。结果与模型组比较,实验组大鼠的骨小梁平均宽度、相对骨体积、骨皮质平均厚度、骨钙、骨小梁单位面积骨细胞数、股骨头和股骨干平均灰度均明显升高,高剂量(0.8g/kg)、中剂量(0.4g/kg)能明显提高骨磷和降低尿钙水平,高剂量还能明显提高血清CT水平(P<0.05,P<0.01)。结论骨松宝胶囊对维甲酸所致大鼠过高的骨转换具有明显的抑制作用,并能提高骨再建能力,对维甲酸所致大鼠骨质疏松有明显的对抗作用。
Objective To observe the anti-osteoporosis effect of Gusongbao capsule (GC).Methods Osteoporosis rat models were induced by gastric infusion of vitamin A acid at a dose of 70 mg/kg for 14 days. The bone morphological and blood biochemical indexes and the amount of calcium and phosphorus in urine excreted every day were determined in both treatment group (treated with Gusongbao) and model control group.Results In the treatment group,the average width of bone trabecula,relative bone volume,average thickness of bone cortex,bone calcium,cell number in per unit area of bone trabecula,and the average gray degree of caput femoris and femoral shaft were higher than those in the moderate group. High dose (0.8 g/kg) and middle dose (0.4 g/kg) of GC increased bone phosphorus level and decreased urine calcium level markedly and high dose of GC also increased serum level of CT (P < 0.05or P < 0.01). Conclusion GC can inhibit the excessive bone transform and promote osteanagenesis and has antagonism effect on rat osteoporosis caused by vitamin A acid.
