[The characteristics of the course of tuberculosis in HIV-infected patients and prophylactic measures]. / Osobennosti techeniia tuberkuleza u VICh-infitsirovannykh i mery ego profilaktiki.

Morbidity in HIV infection and tuberculosis in persons having these two infections in association was analyzed. According to the data for the end of the first quarter of 1997 the presence of association of HIV infection with tuberculosis was found in 91 patients. In 70.3% of cases HIV infection was contacted before the appearance of tuberculosis and in 18.7% of cases, after it; in 11% of cases the order of appearance of these two diseases could not be established. The study revealed that the markedness of the clinical picture of tuberculosis was determined by the progress of HIV infection.

[Obtaining hybridomas producing monoclonal antibodies with different specificities against Mycobacterium tuberculosis of the human and bovine types]. / Poluchenie gibridom, produtsiruiushchikh monoklonal'nye antitela s razlichnoi spetsifichnost'iu k mikobakteriiam tuberkuleza chelovecheskogo i bych'ego vidov.

A procedure for isolation of hybridomes producing monoclonal antibodies (McAB) to tubercle bacilli is described. Specificity of the McABs was studied with the solid phase radioimmune and immunoenzyme tests. Supernatant of tubercle bacilli destroyed with ultrasound was used as antigens. The McABs did not practically react with antigens of the tubercle bacilli atypical forms. Five ascitic monoclonal hybridomes were isolated. Four of them produced antibodies with selective specificity to antigens of bovine tubercle bacilli (M. bovis-8 and BCG) and one produced antibodies to antigens of human tubercle bacilli (H37Rv).

[Stereometric model of respiration with diaphragm electrostimulation]. / Stereometricheskaia model dykhaniia pri électrostimuliatsii diafragmy.

A stereometric model of respiration has been proposed, which is based on the approximation of the surface of the chest and that of the diaphragm by the well-known mathematical functions, which generally calculates the value of respiratory volume as a function of geometric parameters such as the circumference of the chest and torso, the distance between the thoracic vertebrae. The derived formulas may be used as a background material for designing the feedback systems by the respiratory volume in order to maximally approach the electrically stimulated respiration to physiological respiration.

[Medico-technological aspects of the electric stimulation of respiration]. / Mediko-tekhnicheskie aspekty élektricheskoi stimuliatsii dykhaniia.

Clinical results of electric stimulation of respiration in postoperative period by the and respiration electrostimulators are presented in the article. A significant improvement of the function of external respiration and of ventilation of separate lobes of the lungs were observed during the postoperative period after application of these types of stimulators. An experimental research of the influence of different types of pulsed stimulation modulation on the smoothness of inhalation was carried out. A conclusion was drawn about the efficacy of applying in respiratory stimulators of the amplitude/frequency pulse modulation with regulated frequency of impulses that ranged from the "toothed" to the "smoothed" tetanus domain.

[Fluorographic equipment for examining the populations of regions not easily accessible]. / Fliuorograficheskaia apparatura dlia obsledovaniia naseleniia trudnodostupnykh raionov.

The article describes the design of the experimental prototypes of the lightened portable collapsible photoroentgenograph and mobile photoroentgenograph on the basis of the automobile with a higher cross country travel capacity, uAz-452-A, equipped with the chamber PK-110 (GDR). The test results showed that the above photoroentgenographs are convenient and effective for the prophylactic medical examination of the population in the not easily accessible regions.

[Dual control of organ-assisting devices according to the criterion of the activity of the partially replaced organ]. / Dual'noe upravlenie vspomogatel'nymi apparatami po kriteriiu aktivnosti chastichno zameshchaemogo organa.

The authors propose a structure of controlled accessory systems that are intended to substitute the functions of different human organs. It is shown, that during controlled process it is possible to extract the value indicating the variability of the substituted organ activity and to use it as the control criterion.

[Test of the "Biopulse-3" aortic balloon pumping apparatus]. / Ispytaniia apparata "Biopul's-3" pri ballonirovanii aorty.

Experiments on a specially constructed laboratory stand were set up with a view to determining power and dynamic possibilities of the translatory motion drive in the "Biopulse-3" unit when operating an intra-aortic ball-pump and also assessing the service properties of individual unit-blocks intended for injection, measurement and registration. Trial testing showed the drive to the suitable for using in the intra-aortic ballooning.

[Concept of organization of tuberculosis prevention services in Russia]. / Kontseptsiia organizatsii protivotuberkuleznoi pomoshchi naseleniiu Rossii.

Reduced financing of antituberculosis service calls for new organizational measures aimed at more efficient activity of antituberculous institutions. Different forms of the service depending on local needs and resources, special programs are introduced.

[Tuberculosis morbidity in medical workers and the measures for their social protection]. / Zabolevaemost' tuberkulezom meditsinskikh rabotnikov i mery ikh sotsial'noi zashchity.

Tuberculosis morbidity among the medical workers has been studied in 39 territories of Russia. It has been established that medical personnel contract tuberculosis much frequently than the population of Russia on the whole. Morbidity is particularly high among the personnel of institutions of the antituberculous service, being 293.3 per 100,000 working subjects. Tuberculosis morbidity is higher among females (78.8%) and in subjects aged before 50 years (81.4%). Success of tuberculosis control among the medical personnel can be provided by actively solving the problems of tuberculosis prevention, including the organization of health improvement measures under conditions of sanatorium and measures aimed at social protection.
