摘要:

目的:探讨蒙药通拉嘎-5味丸对维甲酸所致大鼠骨质疏松的作用及其机制,为其临床应用提供实验依据。方法:选择60只Wistar雌性大鼠,采用随机区组法分为对照组、模型组、骨肽片组和通拉嘎-5味丸低、中、高剂量组,每组10只,采用维甲酸诱导建立大鼠骨质疏松模型,在给维甲酸同时按分组情况分别给予骨肽片和通拉嘎-5味丸混合液0.3、0.6和1.2 g?kg -1,检测给药前后大鼠血清中钙(Ca)、磷(P)、碱性磷酸酶(ALP)、转化生长因子β1(TGF-β1)和胰岛素样生长因子IGF-1)水平,检测骨灰粉中Ca和P含量,计算股骨长度和宽度指数,HE染色后光镜下观察骨组织形态计量学(骨小梁面积)变化。结果:与模型组比较,通拉嘎-5味丸组大鼠血清中Ca和P水平有增加趋势,但差异无统计学意义(P>0.05);ALP明显降低(P<0.05);TGF-β1和IGF-1无明显变化(P>0.05)。骨灰粉中Ca和P含量有不同程度升高,但差异无统计学意义(P>0.05)。与对照组比较,模型组大鼠股骨最大宽度指数、最小宽度指数明显降低(P<0.05或P<0.01),股骨长度指数降低(P<0.05);与模型组比较,通拉嘎-5味丸低、中、高剂量组大鼠股骨最大宽度指数、最小宽度指数和股骨长度指数差异无统计学意义(P>0.05)。光镜下观察,对照组大鼠股骨可见骨小梁丰富、饱满;模型组大鼠股骨骨小梁稀少、变细;各给药组大鼠股骨骨小梁较模型组有所增宽。与模型组比较,通拉嘎-5味丸低、中、高剂量组和骨肽片组大鼠骨小梁面积增加(P<0.05)。结论:通拉嘎-5味丸对维甲酸诱导的大鼠骨质疏松有一定的干预作用,能够有效阻止维甲酸导致的骨矿物丢失和骨组织纤维结构的改变。

Abstract:

Abstract:Objective  To observe the effect of Mongolian medicine Tonglaga-5 Pill on the osteoporosis induced by retinoic acid in the rats,and to provide experminted basis for its clinical application.Methods 60 female Wistar rats were randomly divided into blank group,model group,Ossptide Tablets group,Tonglaga-5 Pill groups with low,medium and high doses (n=10).The osteoporosis models were induced by retinoic acid in the rats.The levels of serum calcium (Ca),phosphorus (P),alkaline phosphatase (ALP),transforming growth factor β1 (TGF-β1),insulin like growth factor (IGF-1) and bone indexes were detected and the contents of Ca and P in ash were also detected,and the changes of bone histomorphometry of the rats were observed under light microscope by HE staining.Results Compared with model group,the serum calcium and   P contents of the rats in Tonglaga-5 Pill groups were increased,but there were no significant differences(P>0.05);the ALP levels were  decreased significantly(P<0.05);the TGF-β1 and IGF-1 had no significant changes(P>0.05);the contents of calcium and P in  ash were increased in different degrees,but there were no significant differences (P>0.05).Compared with control group,the femur maximum width index and minmum width index of the rats in model group were significantly decreased(P<0.05 or P<0.01);the femur length index was increased(P<0.05).Compared with model group,the femur maximum width index and minmum width index of the rats in Tonglaga-5 Pill groups had no changes(P>0.05).Under light microscope,the rich and full bone trabecula was found in the rat femur in control group;the bone trabecula in model group was decreased,and the bone trabecula in Tonglaga-5 Pill groups was increased.Compared with model group,the trabecular bone areas in Tonglage-5 pill groups and Ossotide group were increased(P<0.05).Conclusion  Tonglaga-5 Pill  displays a certain preventive effect on  the rats with retinoic acid-induced osteoporosis,which can blocks the bone mineral loss,bone tissue structure changes and bone quality decreasing   effectively.
