In view of the established antidiabetic properties of zinc, the present study was aimed at evaluating the hypoglycemic properties of a new zinc-diosmin complex in high fat diet fed-low dose streptozotocin induced experimental type 2 diabetes in rats. Zinc-diosmin complex was synthesized and characterized by various spectral studies. The complexation between zinc ions and diosmin was further evidenced by pH-potentiometric titrations and Job’s plot. Diabetic rats were orally treated with zinc-diosmin complex at a concentration of 20 mg/kg b.w./rat/day for 30 days. At the end of the experimental period, the rats were subjected to oral glucose tolerance test. In addition, HOMA-IR and various biochemical parameters related to glucose homeostasis were analyzed. Treatment with zinc-diosmin complex significantly improved the glucose homeostasis in diabetic rats. Treatment with zinc-diosmin complex significantly improved insulin sensitivity, at least in part, through enhancing protein metabolism and alteration in the levels of muscle and liver glycogen. The assay of clinical marker enzymes revealed the nontoxic nature of the complex. Determination of renal tissue markers such as blood urea and serum creatinine indicates the renoprotective nature of the complex. These findings suggest that zinc-diosmin complex is nontoxic and has complimentary potential to develop as an antihyperglycemic agent for the treatment of diabetes mellitus.

Diabetes mellitus emerges from multiple biochemical and cellular impairments, including decreased insulin secretion from the pancreatic β-cells and impaired insulin action in peripheral tissues. The present study was systematically carried out to evaluate antidiabetic and  antidyslipidemic properties of GOA-111,a herbal extract containing a mixture of Gymnema sylvestrae, Ocimum sanctum leaves and seed kernel of Azadirachta indica  in the ratio of 1:1:1 in ameliorating both the primary and secondary complications of type 2 diabetes mellitus in high fat diet fed low dose streptozotocin induced diabetic rats Experimental type 2 diabetes was induced with a low dose streptozotocin in rats  fed on a high fat diet. Diabetic rats were treated with three different doses GOA 111  (150,300 and 450 mg/Kg b.wt/rat/day)   for 30 days. The toxicological parameters such as AST, ALT and ALP were assayed. Biochemical parameters such as fasting blood glucose, glycosylated hemoglobin, insulin, insulin resistance and lipid profile were measured. Oral treatment with GOA 111 significantly decreased the elevated levels of fasting glucose, glycosylated hemoglobin, AST, ALT and ALP. The insulin level was improved in insulin resistant diabetic rats.  GOA 111 also normalized the lipid profile. Though the  results showed a dose dependent impact on the parameters, a dose of  300mg/Kg B/W/rat/day GOA 111 exerts maximum potential anti-hyperglycemic and antidyslipidemic effects in HFD/STZ-induced type 2 diabetic rats. Key words: GOA 111; High fat diet; Streptozotocin; antidiabetic; antidyslipidemic

In the last years the treatment of type 2 diabetes mellitus (DM2) was carried out using regulators of the brain signaling systems. In DM2 the level of the brain serotonin is reduced. So far, the effect of the increase of the brain serotonin level on DM2-induced metabolic and hormonal abnormalities has been studied scarcely. The present work was undertaken with the aim of filling this gap. DM2 was induced in male rats by 150-day high-fat diet and the treatment with low dose of streptozotocin (25 mg/kg) on the 70th day of experiment. From the 90th day, diabetic rats received for two months intranasal serotonin (IS) at a daily dose of 20 μg/rat. The IS treatment of diabetic rats decreased the body weight, and improved glucose tolerance, insulin-induced glucose utilization, and lipid metabolism. Besides, it restored hormonal regulation of adenylyl cyclase (AC) activity in the hypothalamus and normalized AC stimulation byβ-adrenergic agonists in the myocardium. In nondiabetic rats the same treatment induced metabolic and hormonal alterations, some of which were similar to those in DM2 but expressed to a lesser extent. In conclusion, the elevation of the brain serotonin level may be regarded as an effective approach to treat DM2 and its complications.
