[The role of occupational factors in the development and course of respiratory sarcoidosis].

Aim: The aim of the study was to study the frequency of occurrence of exposure to harmful occupational factors in patients with sarcoidosis of the respiratory organs, depending on the course of the disease.

Materials And Methods: An open prospective study included 121 patients with sarcoidosis of the respiratory system from the age of 21 to 66 years, from 20072019. The diagnosis was histologically confirmed in all patients.

Expression of Galectins-1 and Galectin-3 in Stomach and Colorectal Cancer with Tissue Eosinophilia.

We analyzed the expression of galectin-1 and galectin-3 in tumor tissue in stomach and colorectal cancer with and without tissue eosinophilia. Low expression of galectin-3 was detected in all patients with malignant gastrointestinal tumors irrespective of the presence of eosinophilia. Low expression of galectin-1 was detected only in patients with gastrointestinal cancer associated with eosinophilia.

[Tumor-associated eosinophilia].

The review provides information on current literature on structural and functional features of eosinophilic granulocytes and their role in the pathogenesis of cancer. There are examined data of clinical and experimental studies about an influence of hemic and tissue eosinophilia on the course and prognosis of malignant tumors. Molecular mechanisms of action of eosinophils in tumor pathology are discussed.

[ANALYSIS OF THE RESULTS OF ENDOSCOPIC AND MORPHOLOGICAL STUDIES OF THE STOMACH MUCOSA WITH REDUCED PEPSINOGEN-I IN PATIENTS WITH H. PYLORI (H.P.)--ASSOCIATED GASTRITIS IN TOMSK AND TOMSK REGION].

Aim Of Investigation: To explore and describe the endoscopic picture of HP--associated atrophic gastritis and to analyze the specificity of endoscopic markers indicating the presence of atrophic gastritis, intestinal metaplasia and dysplasia using high-tech methods of endoscopy in comparison with morphological characteristics of atrophic gastritis defining the degree of activity and stage of atrophic gastritis according to the system OLGA.

Materials And Methods: 40 people: males and females aged 40 to 70 years with a reduced level of pepsinogen I and a positive titre of antibodies to H. pylori in serum--were included into the study.

[IMMUNOGENETICS AND PROGRESSION OF CHRONIC VIRAL HEPATITES].

Aim Of Investigation: To estimate the role of polymorphic variants of genes IL4 (C-590T), IL4RA (I50V), TNF (G-308A) and SLC1IAI (D543N) in chronic viral hepatitis progression.

Material And Methods: Overall 121 patients with chronic viral hepatitis C and B.

Results: Study results have demonstrated, that of all investigated polymorphic variants of genes IL4 (C-590T), IL4RA (150V), TNF (G-308A) and SLC11A1 (D543N) in patients with chronic liver diseases of various etiology the <> IL4RA gene variant (II50Val) is associated with HBV-infection chronization.

[Myocardial structural and functional changes in patients with chronic viral hepatitis concurrent with chronic opisthorchiasis].

The aim of the investigation was to study the myocardium in patients with chronic viral hepatitis concurrent with chronic opisthorchiasis. Ninety patients with chronic viral hepatitis, including 52 patients with this disease concurrent with chronic opisthorchiasis, were examined. Doppler echocardiography indicated a statistically significant increase in left ventricular mass regardless of the presence of Opisthorchis infestation.

[The parameters of collagen proteolytic and metabolic systems in chronic liver diseases of viral and toxic etiologies].

Aim: To study a relationship of the plasma activity of elastase-like and collagenase-like proteinases and their inhibitors to hepatic collagen metabolism and to detect the serum markers of fibrosis severity.

Subjects And Methods: Three hundred and fifty-nine patients with chronic liver diseases (CLD), including 118 patients with chronic viral hepatitis (CVH), 113 with CVH concurrent with alcoholic liver disease (ALD), 109 with ALD, and 19 with CLD in the presence of opiomania were examined. The activities of alpha1-proteinase inhibitor and alpha2-macroglobulin (alpha2-MG) were determined by the unified spectrophometric assay from the inhibition of N-benzoyl-arginine ethyl ester hydrolysis.

[Immunoregulatory cytokines and chronization of type C hepatitis: matching of clinical and immunological manifestations].

The study demonstrates significant changes of cytokine-producing ability of mononuclear blood leucocytes in type 'hepatitis, correlating with the degree of hepatic lesion. The results showed that various morphologic types of chronic virus type C hepatitis were associated with disbalance in production of pro- and antiinflammatory cytokines, i.e.
