[The characteristics of the course of tuberculosis in HIV-infected patients and prophylactic measures].

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.

[Concept of organization of tuberculosis prevention services in Russia].

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.

[Hemostasis disorders in patients with pulmonary tuberculosis].

Coagulation studies in 82 patients with pulmonary tuberculosis showed that latent intravascular coagulation occurs not only in patients with active disease, but also in those with marked residual changes. The level of Cl-esterase inactivator may serve as an indicator of the disease prognosis: if its concentration is low, the prognosis is poor. Total fibronectin was measured in 76 patients with different tuberculosis activity.

[Stereometric model of respiration with diaphragm electrostimulation].

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.

[Initial and minor symptoms of tuberculosis in children].

The authors studied the diagnosis of initial and minor tuberculous manifestations in risk-group children using conventional and compementary methods. The latter comprised aspirin and blood chemiluminescence (CL) tests. The aspirin test rejected the infection as a cause of fever in 11.
