Abstract
AIM: Effect of ipriflavone on vitamin A acid-induced osteoporosis in rats was studied. METHODS: Vitamin A acid was used to induce osteoporosis in rats. RESULTS: Vitamin A acid 70 mg · kg-1 · d-1 markedly de- creased the calcium and phosphorus contents of femora, and serum phosphorus, and significantly increased uninary calcium. Microdensitometrical analysis of roentgenography indicated that vitamin A acid 70 mg · kg-1 · d-1 noticeably reduced the density of both distal metaphyses and diaphyses of femora. When ipriflavone at the doses of 50, 100, 200 mg · kg-1 · d-1 was intragastrically administered to rats, it was found that the above- mentioned changes induced by vitamin A acid were dose-dependently inhibited. In addition, ipriflavone at the doses of 50, 100 · 200 mg · kg-1 · d- 1 showed marked elevating effect on serum calcium in rats. CONCLUSION: Ipriflavone is effective in preventing and treating osteoporosis in rats induced by vitamin A acid.
