Histoenzymological Characteristics of Smooth Muscle Cells in Myocardial Vessels: A Comparative Study under Conditions of Increased Left or Right Ventricular Afterload.

Histoenzymological methods were used to study metabolism of smooth muscle cells of intramural myocardial arteries during experimental aortic or pulmonary artery stenosis. Aortic stenosis was accompanied by changes in smooth muscles of the left ventricle manifested by deceleration of tricarboxylic acid cycle, inhibition of oxidation of free fatty acids and their metabolites, flux redistribution in the glycolytic cascade, and inhibition of shuttle systems and biosynthetic processes. Similar metabolic alterations were observed in vessels of the ventricular septum, but they were not revealed in vessels of the right ventricle (except glycolysis stimulation).

[A role of long-term stress and functional properties of the endothelium in the development of autonomic dystonia syndrome].

Objective: To study a role of long-term stress and endothelial function in the development of autonomic dystonia syndrome (ADS) in young patients.

Material And Methods: Authors examined 75 male patients, aged from 17 to 28 years, with ADS including 41 patients without clinically evident symptoms of psycho-emotional stress (group I) and 34 patients with high level of psycho-emotional stress (group II). A comparison group consisted of 21 healthy volunteers.

[The epidemiological risk factors related to labor migration].

The prevention of diseases among migrants becomes a serious problem of public health of subjects of the Russian Federation. The system of public sanitary epidemiological inspection in the field of biological security of the Russian Federation demands a permanent enhancement.
