Vitamin E Improves Cellular and Structural Bone Histomorphometry in an Alcohol-Induced Osteoporosis Rat Model.

Background: Alcohol-induced osteoporosis is a significant health concern, impairing bone formation and enhancing resorption, thereby weakening skeletal integrity. This study examines the effects of palm vitamin E on bone histomorphometry in a male rat model of alcohol-induced osteoporosis. Methods: Three-month-old Sprague–Dawley rats were randomized into seven groups, with one baseline control group (BC) and six experimental groups undergoing a two-phase treatment. In the first month, the control group received normal saline, while experimental groups received intraperitoneal alcohol (3 g/kg) three times weekly. For the subsequent two months, alcohol treatment continued in one group (A), while others received olive oil (C), saline (AN), alpha-tocopherol (AA), or palm vitamin E (AE) orally. Results: Femur histomorphometric analysis post-sacrifice showed that alcohol exposure significantly decreased osteoblastic activity and impaired bone microarchitecture, evidenced by reduced Ob.S/BS, OS/BS, OV/BV, Tb.Th, BV/TV, and Tb.N, alongside increased Oc.S/BS, ES/BS, and Tb.Sp. Both alpha-tocopherol and palm vitamin E improved bone parameters, with palm vitamin E showing superior efficacy except in OV/BV. Conclusions: These findings suggest that palm vitamin E may offer a therapeutic benefit for mitigating alcohol-induced bone damage. [ABSTRACT FROM AUTHOR]
