Abstract

Diabetes mellitus represents an intense metabolic strain for the liver. Inhibitors of angiotensin-converting enzymes (ACEI) are drugs of choice in the therapy of hypertension in coincidence with diabetes mellitus. The effect of ACEI is complex. The attention is drawn to the study of metabolic effects of ACEI. The aim of the study was to investigate whether the administration of ramipril affects the levels of glycated hemoglobin and fructoseamine in the blood of rats with insulin-dependent diabetes mellitus (IDDM), and whether bioenergetics of mitochondria in the liver undergo changes. In our experiments, we used rats of the Wistar strain. The control group was composed of healthy animals. The experimental groups were formed by rats with IDDM evoked by streptozotocine (45 mg/kg) and rats with IDDM + ramipril (10 mg/KG). Both, insulin MONO-ID in the doses of 6 U/kg administered subcutaneously, and water solution of ramipril administered by gastric probe were applied for the period of 8 weeks. We have assessed blood levels of glucose, glycated hemoglobin, fructoseamine and the concentration of cholesterol and triacylglycerols have been assessed also in the liver. Oxidative phosphorylation in mitochondria of the liver were measured...Continue Reading
