Citrus bioflavonoids may offer some protection against the early stage of diabetes mellitus and the development of complications. We investigated the effect of hesperidin on blood glucose levels, hepatic glucose-regulating enzyme activities, serum insulin and adiponectin levels, serum and hepatic lipid levels, and parameters of bone loss in streptozotocin (STZ)-induced marginal type 1 diabetic rats. Weanling male rats were randomly assigned to experimental 3 groups: a control (C) group, a STZ induced marginal type 1 diabetes (S) group, and a diabetes and hesperidin group, and fed their respective diets for 4 weeks. STZ injection increased blood glucose in rats, but the increase was marginal. Serum and hepatic lipids, serum adiponectin and insulin levels were significantly changed by STZ injection. Dietary hesperidin (10 g/kg diet) decreased blood glucose by altering the activity of glucose-regulating enzymes, and normalized the lipids and adiponectin levels, but did not change bone parameters in the marginal type 1 diabetic rats. Hesperidin showed both hypoglycemic and hypolipidemic effects but did not affect bone tissue and bone metabolic makers in STZ-injected marginal diabetic weanling rats without any body weight loss due to STZ injection.
