An Evaluation of Co-treatment of Vitamin E & Zinc on Serum Levels of Calcitonin, Estrogen, Progesterone and Calcium in Ovariectomized Rats

Osteoporosis, an erosive bone defect, is one of the major problems among adults over fifty which makes high expenses and many body psychotic and also causes lots of social side effects on people. Antioxidants and some minerals especially trace elements like zinc may be useful as treatment for osteoporosis. This study was aimed at evaluating the effects of co-treatment of vitamin E and zinc on bone healing parameters. 39 female Vistar rats with weight range of 180-200 gram were studied. 7 rats were selected as control group and others were ovariectomized and divided to 3 experimental groups: treated with Vit. E daily 200 IU / kg (n=9), treated with zinc daily 22 mg/ lit(n=8), treated with Vit. E & Zinc(n=9) and finally 8 rat as sham group. After 1 month levels of Calcitonin, Estrogen, Progesterone, Zinc and Calcium in blood samples were measured and evaluated. Calcitonin levels in blood serum in groups treated with Zinc and Vit. E & Zinc were significant comparing to sham & control groups. Estrogen and Progesterone levels decreased in all experimental groups comparing to control group and occurred changes were significant but Calcium levels in these groups did not show any difference comparing to control and sham groups. Zinc level in serum of all treated groups was altered significantly comparing to control group, although some increased in sham group but not significant. Our result showed using new treatment methods like Vit. E with zinc could prevent bone loss as the serum index measured changes in treatment of osteoporosis.
