[Beta-carotenoids and their potential use in diseases of the digestive tract].

Flying personal with chronic hepatitis received beta-caratinoid vetoron. The latter proved to be an effective immunomodulator improving lipid peroxidation, clinical and morphological characteristics in the personnel with chronic persistent hepatitis. Follow-up gives proves on longer physical fitness for service of those pilots who have taken beta-caratinoids.

[The organizational and methodological aspects of flight medicine expertise in cardiovascular diseases].

Among diseases causing pilot disqualification ahead of time the cardiovascular disorders amount to 60 percent. In this connection there has been generalized the experience of examining the Armed Forces Aviation pilots with cardiovascular disorders beginning from 1979 when by the order of the Ministry of Defence N 220 the Regulations of Aeromedical Examination of pilots have been come into force. The features of examining the pilots with cardiovascular disorders are presented. The present-day methods for the instrumental examination which have been tested in cardiology are systematized in an effort to use them during aeromedical examinations of the pilots. The algorithm of the examined pilots with cardiovascular disorders is set. For the first time the three main groups of approaches to the appraisal of partial or complete loss of the work capacity with known result of diseases. The proposed organization-and-methodologic approach to medical examination of the flying personnel with consideration for the features of stage diagnostics of cardiovascular disorders, individual assessment of their manifestations enables one to handle more qualitatively the aeromedical examination issues with the aim of maintaining the professional working capacity.

[The current approaches to flight medicine expertise on persons with dissociated atrioventricular conduction].

The expert criteria with regard to the pilots with dissociation of atrioventricular conduction in the context of modern cardiological advancements are subject to the considerable improvement. It is demonstrated that the disqualification decision taken with regard to the individuals with the anomalies of conduction system depends not on the type of flying activities but on the paroxysmal supraventricular tachyarrhythmia. The required volume of examination which must include the modern cardiological methods of the noninvasive cardiologic study (ECG monitoring, echocardiography, transesophageal electrophysiological examination). The appropriate changes and improvements included in the Pilot Examination Regulation would take the valid expert decisions in intent to increase the professional longevity of the pilots.

[Prospective trends in the planning optimization of the activities of the epidemiological health institutions of the Army and the Navy].

In the modern stage of the development of medical service the planning of preventive measures must be accompanied with prognostication and economic estimation of the expenses, as well as by veritable definition of the malady. The improvement of methodological approaches in planning is an important part of a system of prophylaxis of infectious diseases. The complex method of the analysis of epidemiological situation must provide for more effective fulfillment of tasks using short and long-term plans of prophylactic works.

[The characteristics of the medical and physical examination of flight personnel with anomalies of the heart conduction system].

The article summarizes the results of examination of a considerable number of flight personnel of the Air Forces with cardiac conduction system abnormalities. The article contains peculiarities and algorithm of examination of such patients. New expert approaches are given concerning this kind of patients as well as methodic recommendations on their medical examination. The data which were obtained during this researches make it possible to improve the work of flight medical evaluation.

[The enzymatic activity of IgG preparations in viral hepatitis].

The activity of the enzymatic activity of the preparations of IgG1, IgG2 and IgG4, isolated from the blood of patients with acute virus hepatitis B and chronic viral hepatitis C resulting in cirrhosis, was studied. The blood samples were found to have DNAase activity significantly exceeding that of immunoglobulins isolated from the blood sera of healthy donors, as well as peroxidase, oxidase and esterase activities, whose level did not significantly differ from those of the donor blood sera. The interaction of IgG preparations with the cations of different metals was studied. The study revealed that the addition of CuSO4 solution at the final concentration of 4.7 x 10(-5) M to the blood samples led to a significant increase in activity in comparison with the initial one (on the average, 7.8 +/- 2.97 times) in all 14 samples. The activity thus observed was partially inhibited by the addition of the solution of staphylococcal protein A. As noted in the course of this study, high DNAase and peroxidase activities of Ig were most frequently observed in patients with cirrhosis of the liver. The difference in the levels of IgG activity between patients with cirrhosis of the liver and patients with virus hepatitis, but no signs of cirrhosis, is not significant.
