['The aim of the present study was to investigate the anti-osteoporotic activity of Maxcal-C in ovariectomy (OVX)-induced osteoporosis in rats.', 'Sham-operated control rats were designated as Group I; Group II animals served as OVX control; Group III OVX control rats treated with Calcium Sandoz (50 mg/kg, p.o.); Group IV and V OVX control rats treated with Maxcal-C (250 and 500 mg/kg, p.o.), respectively. All the aforementioned treatments were given for four weeks after the development of osteoporosis. At the end of the treatment, serum biochemical parameters such as serum calcium and alkaline phosphate were measured. After sacrificing the animals, femoral bone parameters with histology, body weight, and bone breaking strength of 5(th) lumbar vertebra were measured.', 'The treatment with Maxcal-C showed a significant improvement in serum biochemical, femoral bone parameters, and bone breaking strength of 5(th) lumbar vertebra with histopathological changes.'] Does maxcal-C ( a polyherbal formulation ) prevent ovariectomy-induced osteoporosis in rats?
