The study of hypolipidemic properties of Ginger extract on the model of type 2 diabetes induced by dexamethasone
Keywords:Ginger extract, type 2 diabetes mellitus, dexamethasone, hypolipidemic action
Aim. To study experimentally the hypolipidemic properties of Ginger extract against the background of type 2 diabetes.
Materials and methods. The study of the hypolipidemic properties of Ginger extract was performed by the lipid metabolism indices on the model of type 2 diabetes induced by dexamethasone in rats aged 18 months.
Results and discussion. Experimental type 2 diabetes was accompanied with disorder of the lipid metabolism, it was confirmed by the increase of the content triacylglycerides, atherogenic apoB-lipoproteins with simultaneous reduction of high-density lipoproteins and increased release of free fatty acids from the adipose tissue. Under the effect of Ginger extract in the doses of 50 and 80 mg/kg the level of free fatty acids in the blood serum decreased by 38.4 % and 38.9 %, probably due to correction of insulin resistance manifestations and preservation of the insulin control effect on lipolysis. The reliable inhibition of hypertriacylglycerolemia severity by Ginger extract in the dose of 80 mg/kg by 35.1% correlated with a decrease of apoB-LP production in the liver, and it indicated correction of diabetic dyslipidemia. At the same time, the level of the antiatherogenic fraction – high-density lipoproteins – significantly increased by 26.1 and 29.5 % under the effect of the extract in the doses of 50 and 80 mg/kg, respectively, compared to the values of animals of the control pathology. Ginger extract in the dose of 80 mg/kg showed a more expressive ability to normalize the lipid metabolism at the level of the reference drug – “Arphasetin” herbal medicinal product.
Conclusions. Introduction of Ginger extract for 14 days in the doses of 50 and 80 mg/kg on the model of type 2 diabetes induced by dexamethasone was accompanied with a reliable normalization of the lipid metabolism. The use of Ginger extract in the dose of 80 mg/kg is most pronounced at the level of the reference drug – “Arphasetin” herbal medicinal product, corrected the pathological changes in the lipid metabolism characteristic for type 2 diabetes. It allows making a conclusion concerning the feasibility of further studies of the extract exactly in this dose and the prospects of its use as an antiatherogenic drug in the complex treatment of type 2 diabetes.
