Abstract:
Objective To study whether the effects of bone mineral density by a kidney-tonifying herbal fufang treatment in senile osteoporosis mice (P6) is by the mechanism of improving the expression level of GH mRNA and IGF-1 mRNA. Methods The experimental points four groups as following:SAMR1 mice which feed saline lavage,SAMP6 divid as saline lavage group,subcutaneous injection of rhGH group and a kidney-tonifying herbal fufang treatment group. All intervention is one time everyday. After 3 months and 6 months intervention,we measure the BMD and the expression level of the GH mRNA and of IGF-1 mRNA. Results After 3 months intervention,the BMD of R1 group and the Kidney group were higher than the P6 blank group;but there is no difference in BMD between RhGH group and the P6 blank group. The effect of GH mRNA and IGF-1 mRNA expression levels:the R1 group,rhGH and kidney group were higher than the P6 blank group. After six months intervention,the BMD of the rhGH group and kidney group are higher than the P6 blank group. GH mRNA and IGF-1 mRNA expression levels:GH group and kidney group are higher than the P6 blank group. The expression level of GH mRNA and IGF-1 mRNA in four groups has positive correlation. After six months intervention ,we found the positive correlation between the expression level of GH mRNA and IGF-1 mRNA and each part of the whole body BMD. Conclusion A kidney-tonifying herbal fufang can improve the bone mineral density of P6,and its mechanism may be related to improve expression level of GH mRNA and IGF-1 mRNA.
