Purpose. The study is focused on development of high-fat, high-carbohydrate diet-induced experimental model of metabolic syndrome (MS) in rats.Materials and methods. The 6-week old Wistar rats (n = 20) were used for study. Rats were separated into control and experimental groups. The rats from the control group were fed standard rat chow. The rats from the experimental group had a high-fat, high-carbohydrate diet rich in lard (17%) and fructose (17%) and drank 20% fructose solution. At the end of the study, body weight and blood pressure (BP) were assessed. After 12 weeks of a diet load, an oral glucose tolerance test (GTT) and insulin tolerance test (ITT) were carried out. Lipid and protein biochemical parameters in plasma were analyzed. Adipose tissue and liver were measured at the end of the study. The levels of triacylglycerol (TAG) and cholesterol (Сh) in the liver were determined by enzymatic methods.Results. High-fat, high-carbohydrate diet feeding in rats for 12 weeks led to BP elevation and increase in the adipose tissue/body weight ratio. Hyperglycemia, impaired glucose tolerance and insulin resistance were found in rats with MS by means of GTT and ITT. Elevation of plasma TAG level was observed in the experimental group, although plasma total Сh and HDL-Ch did not differ from those of controls. Liver/body weight ratio and the level of TAG and Ch in the liver were elevated in rats with MS.Conclusion. Experimental rat model of diet-induced MS reproduces many aspects of MS in humans. This model may be useful for studying the pathophysiology of MS and methods for its prevention and treatment. more...

Very little research is devoted to the study of communication systemic immunological changes and local immunological changes in the tissue of the thyroid in autoimmune thyrophaties. The goal of the research was to establish immunologic and morphologic predictors of clinical course and functional outcomes of Graves’s disease (GD).Material and methods. We examined 45 patients with GD (14 men and 31 women) aged 18–55 years (47.0 (35.0–53.0)) years, matching the following criteria: a verified diagnosis GD, accommodation in Tomsk oblast and the Tomsk not less than 10 years, the patient's consent for the study. The control group included 30 people, with an average age of (45.3 ± 5.6) years and was comparable by age and sex with GD patients. The study included: definition of the standard for GD hormonal and serological profile (free T4, free T3, and TSH, antibodies to TPO, antibodies to the TSH receptor), the cultivation of mononuclear leukocytes in complete culture medium within 24 hours with subsequent determination of interleukins concentrations (IL-2, IL-4, TNF-alpha) in culture medium using enzyme-linked immunosorbent assay, determination of the number of blood cells carrying membrane-bound receptors to IL-2, IL-4, TNF-R1 by flow laser cytometry on cytometer BD FACS Canto tmΙΙ (USA) using labeled monoclonal antibody, the standard postoperative histological examination of thyroid gland tissue samples and immunohistochemical detection in samples of thyroid tissue receptors to IL-2, IL-4, TNF-alpha.Results. On the basis of the received results it is possible to allocate 2 clinical-immunologic and morphologic cluster of autoimmune hyperthyroidism syndrome in patients with clinical diagnosis of GD. The first includes the formation of 1 and 2 histological options GD (minimally expressed monocytes infiltration, lack of oncocytic transformation of thyroid epithelium), with some clinical characteristics (persistent and pronounced hyperthyroidism, the large size of goiter, higher titer of receptor TSH-antibody and smaller TPO-antibody, diffuse nature of the lesion), and the second – is represented by 3d histological option with oncocytic restructuring of follicular epithelium, expressed the monocyte/macrophage infiltration with the TNF-RI expression and clinical patterns, including: the older age group of patients, the smaller size of goiter, the emergence of “pseudo nodes” ultrasound, reflecting the presence of lymphoid follicles-infiltrates, more lenient for hyperthyroidism. Probably, that the 2nd cluster is a combination of “classical GD” with autoimmune thyroiditis, however, a set of clinical and laboratory-instrumental signs led to the fact that these patients were in the group of GD patients.Conclusion. This approach (combining study of indicators of systemic and local tissue-specific autoimmune inflammation) is a promising from the point of view of separate parts coverage in the autoimmune thyroids diseases pathogenesis, approximating researchers to develop immune based therapeutic technologies. more...

A method of local adrenal organ-preserving cryolysis using a porous nickelide titanium cryoprobe created for this purpose was developed in experiments in 14 dogs. The efficacy of the method was demonstrated by the morphological evidence and hormone tests. more...

The surgery results analysis of 615 patients with various thyroid disorders was carried out. The percentage of postoperative hypoparathyroidism amounted 1,14%. In order to prevent postoperative hypoparathyroidism in the course of experiment, the method of endovascular autotransplantation of accidentally removed or deprived of supply parathyroid glands was developed. more...

On a thyroid disease conservative correction background, preoperative period is accompanied by the upcoming surgery risk and its optimal level assessment, as well as assessment of specific complications development possibilities. Typically, the thyreopathies pathogenesis is accompanied by the thyroid gland functional activity disorder, which provides variety and, in some cases, the clinical picture similarity. Also, due to metabolic processes endocrine regulation fail in the whole organism, it causes disorders development in various organs and systems. Each thyreopathy is characterized by the relevant homeostasis indicators and clinical finding, in the development of which, the role of thyroid gland hormone production variant (hypothyroidism, hyperthyroidism, euthyroidism) and the deviation intensity level are not significant only as a pathological process marker, but also determine the compensation of an adaptive disorder tactics in pre- and postoperative period. more...

The 105 patients were undergone the medical observation after operations of various volume on thyroid gland. The patients were divided into 3 groups — patients without additional changes (n = 74), with nodes in residual tissue (n = 20), patients with glandular tissue after thyreoidectomy (n = 11). The amount of relapses was increasing with prolongation of postoperative period. For specification of relapsing nodules and thyroid residue spreading after thyreoidectomy the complex radiological examination is proposed. more...

The study included 557 patients with diffuse nodular colloidal goiter and different functional state of thyroid gland after routine surgeries. In the postoperative period was diagnosed hypothyroidism and in its presence the relapse nodulation in thyroid residue. In order to prevent the development of postoperative hypothyroidism, organopreserve surgical methods of the local cryodestruction of pathologic area thyroid gland and autotransplantation of intact thyroid tissue were suggested. more...

Surgical thyropathy correction is inevitably accompanied by specific change s in hormonal status. We have analyzed the ada ptation mechan - isms and compensat ory and adaptive reactions responsible for the whole life-support system of organism. On the basis of a number of organism homeostats nonspecific mechanism s of resistant and tolerant realisation strategies of long-term adaptation were studied, suppositions were made on possible effective course of adaptation reactions in the conditions of healthy thyroidal issue transplantation and cellular therapy use. more...

The advantages of compensatory – adaptive reaction here studied in 67 patients with duodenal ulcer operated on by organ – preserving techniques Bilrot-I and duodenoplasty. The advantages of adaptation include the values of immune (cellular and humoral immunity) and hormone status (insulin, cortisol, ACTG), peripheral blood indexes (morphological composition and biochemical indexes), vegetative system status and general adaptation syndrome characteristics. more...

Abstract The efficiency of autotransplantation of the thyroid tissue into the greater omentum was demonstrated in experiments on rats. High viability of the transplant and restoration of the hormonal thyroid activity were attained after a single injection of the cell suspension of autologous adherent bone marrow cells directly into the transplant.
