Peculiarities of Metabolism of Rats with Fructose-induced Insulin Resistance Against the Background of Congenital and Acquired Iodine Deficiency

Abstract

Animals following a high-fructose diet during eight weeks, have experienced changes in metabolism and the signs of insulin resistance have developed. Under such conditions, moderate hyperglycemia, hyperinsulinemia, hyperuricemia, an increase of the level of glycosylated hemoglobin in whole blood were observed. The significant role of the HOMA-IR index, as an early marker of carbohydrate metabolism disorders at the stage of pre-diabetes, has been confirmed. In experimental animals against the background of the high-fructose diet, the changes in the lipid spectrum of the blood were revealed: an increase of the total cholesterol level, low-density lipoproteins, triglycerides against the background of a high-density lipoproteins decrease. These disorders and a significant increase of the atherogenicity reflect the development of secondary dyslipidemia. In this case, the disorders of carbohydrate metabolism were combined with the degree of dyslipidemia. Males were found to have at increased risk of development the insulin resistance and comorbid pathology. Iodine deficiency, especially of congenital nature, is an aggravating factor of metabolic disorders. The obtained data can serve as a basis for extend of preventive measures and identification of the priority treatment schemes for type 2 diabetes mellitus in residents of endemic regions.

The Examination of Remodeling Processes of Hard Periodontal Tissues in Rats with Disorders of Pancreatic Incretory Function

“…IR was simulated by replacing the drinking water of rats with a 10 % fructose solution for 8 weeks [9]. For the reproduction of iodine defi ciency state an experimental model was used, according to which the animals were on an iodine-defi cient diet during the experiment [10].…”
