骨疏丹抗骨质疏松的药理作用

目的观察和分析骨疏丹对糖皮质激素强的松龙所致实验性骨质疏松大鼠的防治作用。方法将60只Wistar雄性大鼠随机分为6组:对照组,模型组,骨疏丹大、中、小剂量(3、1、0.3 g/kg)组及骨疏康组。观察骨疏丹对强的松龙所致实验性骨质疏松大鼠血液、骨组织指标及骨密度,骨生物力学的影响。结果8周后,骨疏丹可明显增加强的松龙所致实验性骨质疏松大鼠的骨密度、骨生物力学以及血骨钙素,骨钙、磷的量,与模型组相比有显著差异,并呈剂量依赖性关系。结论骨疏丹可使强的松龙所致实验性骨质疏松大鼠骨钙、骨磷,血骨钙素的量提高,骨密度增加,骨生物力学提高,有明显的防治骨质疏松作用。

Pharmacological effects of Gushudan against osteoporosis

Objective To investigate the preventive effects of Gushudan on osteoporosis in rats after administrated prednisolone.Methods Wistar male rats(60) were divided into six groups: control group,model group,Gushudan groups(3,1,and 0.3 g/kg),and Gushukang 1 g/kg group.The effect was observed by measuring the levels of blood calcium,blood phosphorus,blood BGP content,bone calcium,bone phosphorus,bone density,and hone biomechanics.Results After eight weeks,Gushudan significantly increased the bone density,bone biomechanics,blood BGP content,bone calcium,and bone phosphorus in model group rats.Conclusion Gushudan could increase bone density,bone biomechanics,blood BGP content,bone calcium,and bone phosphorus induced by prednisolone.These results suggest that Gushudan has a distinct preventive effect on osteoporosis rats.
