[Nuclear-medical equipment in the Research Institute for Medical Instrument-making].

The activity of the department for emission introscopy of the Research Institute for Medical Instrument-Making ("ZAO VNIIMP-VITA") is described in the article. A list of developed and commissioned devices and instruments for the field of nuclear medicine is presented. Methods of elaboration of some sophisticated instruments and units designed for radio-biochemical and radio-immunologic examinations as well as methods of elaboration of scintillation gamma cameras, tomograph GKS-301T, medical dosimeters and of other devices are also described.

[Adsorption and desorption of the radionuclide 133Xe on carbon adsorbents with varying porous structures].

The paper concerns adsorbents with different porosity intended for adsorption of gaseous 133Xe from the flow of a gas-air mixture exhaled by the patient undergoing the diagnosis, for instance, of the pulmonary system or cerebral blood flow. The data obtained were visualized on a gamma-chamber. An adsorbent exhibiting the highest adsorption capacity was selected. It has been shown that transport porosity of adsorbents does not play any significant role in adsorption of gaseous 133Xe. During adsorption, a much greater role is played by binding energy.

[Right-to-right arteriovenous shunting in the compensation of pronounced disorders of pulmonary ventilation].

The mechanism of compensation for disorders of ventilation after pulmonary tissue resection is discussed. It is shown that these disorders are attended with reduction of arterial pulmonary blood flow and that angiospasm occurs in the postcapillary part of the vascular channel of pulmonary circulation. The compensatory effect is achieved by a right-to-right arteriovenous shunt which prevents extreme increase of pressure in the pulmonary artery in ventilation disorders.
