[Various mechanisms of heart failure in liver diseases].

The article is a review of the literature on the problem of heart disease in liver cirrhosis of different etiologies (alcohol, amyloidosis, hemochromatosis, viral lesions of the heart). Examined in detail the pathogenesis of cirrhotic cardiomyopathy and diagnosis, occurring in cirrhosis of any etiology. This article presents a noninvasive methods of diagnosis of myocardial fibrosis using serum markers of fibrosis, myocardial fibrosis degree of calculation on the basis of echocardiography and ECG.

[The role of persistence and virulence factors in microecological changes in a humans].

The patterns of persistence and virulence factors expression in the representatives of human microbial biocenosis depends on a complex of the environmental conditions: influence of microbes-symbionts, biotope peculiarities, properties of microorganisms located within eukaryotes. Interactions of symbionts in pairs "indigen-indigen" isolated from mucous membrane of tonsils in healthy persons, did not lead to changes in expression of pathogenic properties. Interinfluence in pairs "pathogen-indigen" and "indigen-indigen", isolated from patients with chronic tonsilitis were accompanied by an increase of anti-lysozyme, hemolytic and lecithovitellase activities.

[Interaction between bacteria and erythrocytes and their role in the development of infectious anaemia].

The concentration of hemoglobin in blood of patients with pyoinflammatory diseases was shown to depend on the ability of bacteria to interact with erythrocytes. Bacteria with high hemolytic activity (> or = 70% hemolysis) and anti-hemoglobin activity (>3 g/1) were isolated from pyoinflammatory foci of patients suffering from anaemia. Structural changes were investigated in vitro and in vivo erythrocytes in terms of their interaction with microorganisms by electron microscopy.

[Interaction of bacteria and red blood cells].

The interaction of staphylococci, streptococci, meningococci, enterobacteria, leptospires and other microorganisms with red blood cells is considered. Three forms of the interaction of bacteria and red blood cells are discussed: adhesion, the influence of secretory factors on red blood cells, the action of pathogenic bacteria on hemoglobin. The applied aspects of the interaction of bacteria and red blood cells in the human body are presented in accordance with the results of clinical and laboratory studies.

[The use of the antipyrine test in assessing liver function in patients with insulin-dependent diabetes mellitus].

The antipyrine test in the authors' modification was used for investigation of liver function in patients with insulin dependent diabetes mellitus. The drug was administered per os a dose of 15 mg per 1 kg of body mass. Its concentration was determined in saliva spectrophotometrically and calculated a period of its half-life [correction of semielimination] (T1/2).
