Parameters of thyroid and adrenal cortex hormones in cats of different breeds

Abstract

The thyroid and adrenal glands are one of the most important organs of humoral secretion. The hormones produced by them take an active part in the growth and development of the animal body. Thyroid hormones accelerate metabolism in many tissues, enhance the catecholamine response, have positive inotropic and chronotropic effects, and produce catabolic effects on muscle and adipose tissue. In addition, they contribute to normal growth and physiological development. Diseases of the thyroid gland and adrenal glands in small Pets are not uncommon. For a timely diagnosis and control of the effectiveness of treatment (in the case of the development of the disease), it is necessary to know the level of hormones, and the lack of normative indicators of thyroid and corticosteroid hormones in cats interferes with full diagnosis and therapy. We conducted a study to determine the parameters of thyroid and adrenal hormones in healthy animals. The endocrine glands activity in cats was studied in Belgorod veterinary clinics. Animals for the formation of groups were selected taking into account the age, conditions of keeping and feeding, the results of clinical examination; differentiated groups according to breed characteristics.The animals were examined, palpated, and their hormonal status was investigated. From healthy (according to the results of clinical examination) cats, blood was taken to determine the concentration of thyroid and corticosteroid hormones. Parameters of thyroidstimulating hormone, thyroxine, triiodothyronine, adrenocorticotropic hormone, and cortisol in General and free forms were determined. The results of the study determined the activity of the thyroid and adrenal glands in cats of different breeds. The data obtained allow us to talk about breed differences in the levels of thyroid and adrenal hormones. The highest indicators of thyroid and corticosteroid hormones were found in the Persian breed group, and the lowest in the Abyssinian group.
