Diabetes mellitus (DM) has been known asone of the main universal health difficulties. Conferring to the estimated, 382million people suffering from this disease, which is an amount equal to 8.
3% ofthe population and Type 2 diabetes making up about 90% of the cases(1,2).Trace elements display a central taskin the suitable functioning of carbohydrate and lipid metabolism by variousmechanism(3,4). Vanadium is a group 3d transition metal that occurs in thehumans as a micronutrient and performances as an inorganic cofactor in manyenzymatic reactions, having and assisting cellular bioactivities(5-7).
Primaryattention to varied biological actions of vanadium focused onanti-diabetic activities but has shifted to anti-cancer and anti-parasiticdrugs(7,8).Vanadyl sulfate hasbeen used in humans as insulin-mimetic salt and thus controls both type 1 andtype 2 DM. Vanadyl sulfate defends the beta cells of Islets of Langerhans thus endorsinginsulin production and discharge, leading to improved blood sugar regulation(9-11). On the other hand some studiesfound that vanadium is not effective against hyperglycemic states to the extentshown by some other researchers. Another recent study shows that vanadium isnot effective against Diabetes mellitus at all(12).Thereare also different opinions about the effect of vanadium on insulin. Somebelieve that vanadium increases insulin secretion, but others believe that thiselement increases the sensitivity of insulin, rather than increasing itssecretion(13,14).
Dueto the rising occurrence of diabetes especially type 2 diabetes, multiform studyintended at aborting and remedy is one of the universal investigate priorities.The present study was designed because of conflicting results regarding theeffect of vanadium on metabolic profiles. To the best of our facts, this is thefirst study to evaluate a new modified method for induction of type 2 diabetesin rats and so to estimate vanadyl sulfate effect on PPAR-? and TNF-? geneexpression and so related metabolic responses, simultaneously, in vivo.
