[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.

Trace Elements in the Lung Tissue Affected by Sarcoidosis.

In the lungs of 76 patients with verified sarcoidosis, 28 chemical elements were identified with neutron activation analysis. High levels of Ca, Fe, Cr, Co, Cs, Eu, Lu, Th, Hf, Au, and U and low level of Na compared to the control samples were determined in sarcoidosis. There were no significant differences in the content of Zn, Rb, La, Sm, Sr, Nd, As, Br, Ag, Tb, Sc, Ta, Sb, Ba, and Yb.

[Disorders of Vasoregulative Endothelial Function, Echocardiographic Assessment of Myocardial Dysfunction and Hemodynamics of Pulmonary Circulation in Cirrhosis of the Liver].

Aim: to study relationship between parameters of intracardiac hemodynamics assessed by Doppler echocardiography and functional activity of endothelium, hepatic blood flow and severity of portal hypertension in patients with cirrhosis of the liver (CL) of different etiology.

Results: We found that changes of structural and functional parameters of the heart in LC depended on the stage of compensation of portal hypertension and were accompanied by rearrangement of parameters of intracardiac hemodynamics. Pulmonary arterial hypertension (PAH) was found in 11.

[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.

[Somatopsychic manifestations in patients with chronic viral hepatitis].

The aim of the work was to study somatopsychic manifestations in patients with chronic viral hepatitis (CVH). MMPI profiles, state and trait anxiety were assessed in 110 patients. Boundary psychic problems were evaluated using the Beck scale.
