The effect of iodosteviol glycoside on hormonal status and the level of proinflammatory cytokines in experimental hypothyroidism

Abstract

Aim. Study of the hormonal status and the level of pro-inflammatory cytokines in the blood plasma in experimental hypothyroidism and the effect of the organoiodine complex with rebaudioside A. Materials and methods. Endemic thyroid dysfunction was modeled in sexually mature male white rats by daily intragastric administration of thiamazole for 21 days at a dose of 25 mg / kg. In the blood serum, the content of thyrotropin, total and free thyroxine, total triiodothyronine, testosterone, luteinizing, follicle-stimulating and parathyroid hormones, corticosterone, interleukins-1-beta and -6, tumor necrosis factor-alpha was studied. The animals were divided into four groups of 10 each: control, experimental, comparison and main. Results. The development of hypothyroidism was characterized by an increase in the content of thyroid-stimulating, luteinizing, follicle-stimulating and parathyroid hormones, as well as pro-inflammatory cytokines. At the same time, testosterone levels decreased, while corticosterone levels were within physiological fluctuations. Conclusion. The use within 30 days of the recovery period after the development of hypothyroidism of the iodosaccharide complex based on steviol glycoside rebaudioside A used in the food industry daily at a dose of 25 mg / kg of rat weight led to the normalization of the content of the studied hormones and cytokines in the blood plasma, characterizing the effectiveness of the new organoiodine product.
