[Radial methods of investigation in expert assessment of some liver disease in pilots].

Potentialities of the present-day methods of radial diagnostics of some liver diseases in pilots have been studied. 79 pilots with liver diseases were investigated. A high degree of correlation between the changes observed in laboratory studies and ultrasonic picture of the liver has been revealed. The pattern of these changes is considered to be a result of chronic disorder of the liver blood flow caused by decreasing of pressure in the liver arteries and increasing of the venous pressure during accelerations. The fan-shaped type of blood circulation infers that these changes propagate in the periphery-to-center direction and, therefore, changes in the peripheral parts of the right lobe of the liver, i.e. the most poorly blood supplied regions, are initiated by the developing connective tissue component. The ultrasonic investigation proved to be the major and most efficient diagnostic procedure of radial investigation within the program of medical qualification of flying personnel with liver diseases. Methods of mathematical analysis raised the value of diagnostics in 79.4 per cent of the observations through assessment of the quantitative indices of the severity of changes in the liver parenchyma.

[Effect of hypokinesia and varying microclimate on vestibular function].

The functional state of the vestibular system of the bed rested man is characterized by a decrease of the nystagmic parameters, increase of autonomic reactions and elongation of illusory sensations. This may reduce the static and kinetic stability of man to acceleration. The bed rest induced vestibular changes can be attributed to the functional changes in higher compartments of the central nervous system. The influence of an altered atmosphere on the vestibular function is insignificant.
