BACKGROUND Two-stage surgery including right ventricular outflow tract (RVOT) stenting with subsequent total surgical repair (TSG) has been suggested as a promising curative option in infants with tetralogy of Fallot (ToF) having comorbidities such as low body weight. However, data on clinical outcomes of such approach and tissue response to RVOT stenting in underweight infants are scarce. METHODS We recruited 16 underweight (

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.

The complex immunologic estimation of inflammatory reactions in bronchial contents at 30 patients with various phenotypes of a serious bronchial asthma is spent. It is established that the population structure of lymphocytes and cytokines a profile of the induced phlegm reflects expression and character of inflammatory disturbances in respiratory tracts that will allow to use the given non-invasive method for revealing of molecular markers of serious forms of a bronchial asthma. At the serious terapevticheskirefractory form of a bronchial asthma «brittle» a phenotype in respiratory tracts total СD4+ -, СD19+ -cell and concentration interleukina-4 against depression interleukina-10 is enlarged. At the serious form of a bronchial asthma of a phenotype «the chronic asthma with the fixed bronchial obstruction» in a bronchial secret prevails CD8+ -lymphocytes, concentration interleukina-8, the transforming growth factor-β increases.

In the present research the complex cytologic and biochemical estimation of a condition induced sputum at 19 patients with the heavy therapeutic-sensitive form of a bronchial asthma and 18 patients with chronic obstructive disease of lungs is lead. Dominating morphological and biochemical markers of an asthma became the raised number of macrophages, lymphocytes, and eosinophils at decrease in functional activity neutrophil elastase and increases activation properties. Progressing of destructive and fibrous processes at patients with heavy form chronic obstructive pulmonary disease occurs on a background active neutrophil and lymphocytes reactions in a mucous membrane of bronchial tubes that proves to be true high activity elastase and falling of functioning proteinase inhibitor.

The inflammatory-reparative reactions of sclera after different injury were studied. In animals of the 1st group carried out conjunctivotomy and surgical diathermy. In animals of the 2nd group carried out conjunctivotomy. Biomicroscopy, histologic and morphometrical studies were carried out. The results demonstrate surgical diathermy of sclera leads to intensification of local inflammatory reaction and is a risk factor of excessive regeneration in glaucoma filtration surgery.

The use of venous flaps is controversial. The mechanism of perfusion of venous flaps is still not fully understood. The research was conducted on 56 white rats. In our experimental work we studied two different models of venous flaps: pedicled venous flap (PVF) and pedicled arterialized venous flap (PAVF). Our results showed that postoperative congestion was present in all flaps. However 66.7% of all pedicled venous flaps and 100% of all pedicled arterialized venous flaps eventually survived. Histological examination revealed that postoperatively the blood flow in the skin of the pedicled arterialized venous flap became «re-reversed» again; there were no differences between mechanism of survival of venous flaps and other flaps. On the 7-14th day in the skin of all flaps were processes of neoangiogenesis and proliferation. Hence the best scenario for the clinical use of venous flaps unfolds when both revascularization and skin coverage are required.

The aim of the study was to examine the system of tumor necrosis factor α(TNFα), depending on the functional and morphological outcome of Graves’ disease (GD). It has been shown that activation of TNFαis associated with a “soft” and “benign” clinical course of GD and appearance of morphological markers of autoimmune thyroiditis (Hurthlecells transformation of thyroid epithelium).
