Fig. 5From: Metabolomics and physiological analysis of the effect of calcium supplements on reducing bone loss in ovariectomized rats by increasing estradiol levelsEffect of CaCO3 on the histology of the femur. Histological sections (HE.25×) of trabecular bone from rats in different groups were observed. OVX caused an obvious loss of trabecular bone in the OVX-LC group, and the administration of 750 mg/kg or 2800 mg/kg CaCO3 significantly rendered the loss of trabecular bone in OVX-LC ratsBack to article page
