Sažetak
Retinoic acid-induced osteoporosis (RBM) is one of the most common causes of secondary osteoporosis. This study tested the anti- osteoporetic effect of quercetin in RBM-induced bone loss model (RBM). After 14-day supplementation of 13cRA to induce RBM, rats were administered with quercetin (100mg/kg) or alendronate (40mg/kg). We analysed changes in body and uterine weight of animals, femoral geometric characteristics, calcium and phosphorus content, bone weight index, bone hystology, bone mineral density (BMD), markers of bone turnover, lipid peroxidation, glutathione levels and SOD, CAT activity of liver, kidney spleen, and ovary as well as biochemical and haematological variables. In comparison to the control RBM rats, the treatment with quercetin increased bone weight index, BMD, osteocalcin level, femoral geometric characteristics, calcium and phosphorus content in the 13cRA-induced bone loss model. Histological results showed its protective action through promotion of bone formation. According to the results, quercetin could be an effective substitution for alendronate in 13cRA-induced osteoporosis. Good therapeutic potential of quercetin on rat skeletal system is based partly on its antioxidant capacity and estrogenic activity.
