Safflower has been cultivated in Korea and thought to have excellent effects on bone in oriental medicine and folk remedy and has been taken for a long time. Safflower is thought to be helpful for the development and sustenance of bones according to the result of recent assay of its components. Otherwise, any reliable experimental data have not been suggested so far. We have carried out this study to examine the prophylactic effects of safflower-seed-powder on the prevention of osteoporosis induced by the ovariectomy 12 Weeks-old Sprague-Dawley rats weighing about 230 g was kept in the experimental condition and used in this study. Animals were taken 0.3 g of safflower-seed-powder once a day for 1, 3, 5, and 7 weeks after ovariectomizing both ovaries and observed the fine structure of tibia. Tissues were fixed with traditional SEM preparation methods and decalcified for 10 hours with 10% nitric acid and dehydration, drying, and gold-coating were followed by the routine procedures and observed with scanning electron microscope (Hitachi, S-450). Loss of bone was started just after ovariectomy and thickness of bone from the medullary cavity to the compact bone was reduced and the extension of medullary cavity was serious in the control group of 7 weeks. Experimental groups taken safflower-seed-powder showed similar findings from 1 week to 7 weeks. These results suggest that the safflower-seed-powder is thought to be efficient for the prevention of osteoporosis owing to the deficiency of female sex hormone.
