Effect of Losartan on the Antioxidant Status of Rats with Diabetes Mellitus
VPLYV LOSARTANU NA ANTIOXIDAČNÝ STAVPOTKANOV S DIABETES MELLITUS
Predmetom štúdia bolo sledovať vplyv podávania antihypertenzívneho lieku losartanu na:
1) antioxidačny stav potkanov s experimentálnym inzulíndependentnym diabetes mellitus; 2) stav oxidačného poškodenia reprezentovaného tvorbou látok, ktoré reagujú s kyselinou tiobarbiturovou(TBARP) a 3) niektoré metabolické parametre. Podávanie losartanu vyznamne neovplyvnilo koncentráciu glukózy, cholesterolu, triacylglycerolov a kyseliny močovej v plazme kontrolnych a diabetickych zvierat. V pečeňovom tkanive sa po podaní losartanu znízila koncentrácia triacylglycerolov,koncentrácia cholesterolu nebola ovplyvnená. Ďalej sa zistilo, ze podávanie losartanu zvyšilohladinu antioxidantov rozpustnych v lipidoch v plazme diabetickych potkanov, čo môze byš príčinouzisteného znízenia obsahu TBARP v plazme diabetickych potkanov.

Summary
The aim of this study was to monitor the effect of the administration of antihypertensive druglosartan on: (1) the antioxidant status of rats with experimental insulin-dependent diabetesmellitus; (2) oxidative damage which is represented by the production of compounds which can reactwith thiobarbituric acid (TBARP), and (3) some metabolic parameters. Losartan administration didnot significantly influence the concentration of glucose, cholesterol, triacylglycerol, and uric acid inthe plasma of control and diabetic animals. In the liver tissue, the concentration of triacylglycerolsdecreased after losartan administration, but the concentration of cholesterol did not change. Thepresent authors have found that losartan administration increased the levels of water solubileantioxidants in the plasma of diabetic rats, which can result in a decrease of the TBARP levels inthe plasma of diabetic rats.
Key words:
antioxidant status - losartan - diabetes mellitus - oxidative stress
