Influence of Gusongbao Capsule on Osteoporosis in Ovariectomized Rats / 中药新药与临床药理

ABSTRACT

Objective To observe the therapeutic effect of Gusongbao capsule for osteoporosis. Methods Experimental osteoporosis rat models were established by extirpation of bilateral ovaries of female rats. Bone morphological indexes, blood biochemical indexes, and daily output of calcium and phosphorus in urine in the Gusongbao treatment group and control group were determined. Results Compared with the control, the average width of bone trabecula, relative bone volume, average thickness of bone cortex, bone calcium, and the average gray degree of femoral head and femoral shaft were high, and the serum calcitonin (CT) and blood calcium increased markedly in the treatment group. High-dose and moderate-dose Gusongbao increased number of osteocytes in per unit area of bone trabecula, decreased serum alkaline phosphatase (ALP) level and reduced the daily output of urine calcium. Conclusion Gusongbao capsule can obviously inhibit the excessive bone transformation and promote the re-construction of bone and exerts an antagonistic effect on osteoporosis in ovariectomized rats.
