چکیده

OBJECTIVE Vanadyl sulphate, an inorganic tetravalent salt of transition metal vanadium is conventionally used to treat diabetes and by athletes as body-building supplement. Vanadyl sulphate is a constituent of many supplements and herbal preparations available over the counter in many parts of the world. In this study the efficacy of the salt as hypoglycaemic agent and its effects on lipid profile were determined when administered in therapeutic dose range (in humans) to healthy Sprague Dawley rats for a considerable duration. METHODS One hundred and five rats were randomly divided into three groups of 35 rats each. Animals of all three groups were provided normal rodent diet and water ad libitum. Group I animals were administered 0.5 ml plain water through oral gavage while group II and group III rats, 0.25mg/Kg/day and 1.2mg/Kg/day vanadyl sulphate respectively for 24 weeks. At the end of 24 weeks intra-cardiac blood sampling was done and blood glucose, insulin and lipid profile were measured. RESULTS There was significant decrease in plasma glucose, insulin and HDL-c levels while LDL-c, TGs and TC levels were significantly increased in a dose dependent manner in treated groups. CONCLUSIONS Our study showed that vanadyl sulphate possesses hypoglycaemic effect in healthy rats while insulin levels are also decreased which may be secondary to hypoglycaemia. Moreover it causes unfavorable derangement of lipid parameters in treated rats. In conclusion vanadyl sulphate though contains significant hypoglycaemic effects; its use in humans may be re-evaluated to establish its safety in relation to lipid profile.
