| Abstract: | The effects of mildronate 3(2,2,2-trimethylhydrazinium) propionate dihydrate], γ-butyrobetaine (GBB) and their combination (neomildronate) on the level of thyroid hormones and some intermediates of basal metabolism (free fatty acids, triglycerides, glucose) in serum of laboratory rats with various dysfunctions of thyroid glands including idiopathic hyperfunction and also hypofunction induced by administration of 6-propyl-2-thiouracil (PTU) or L-carnitine administration. Intraperitoneal injections of mildronate (150 mg/kg) during 20 days to male Wistar rats with elevated level of thyroid hormones and basal metabolism normalized thyroxin level and parameters of lipid metabolism in serum. Administration of the compounds studied to rats with hypothyroidism induced by administration of PTU or L-carnitine did not influence natural recovery of the hormonal level. Possible biochemical role of these pharmacological treatments is discussed in terms of in regulation of thyroid gland function. |
