[Increasing the radon concentration in natural water without the use of radium preparations]. / Ob uvelichenii kontsentratsii radona v prirodnoi vode bez primeneniia preparatov radiia.

The method of increasing radon concentrations in natural radon water without radon generators is based on radon redistribution between various water volumes, water and air. Radon is extracted from hot radon water with subsequent solution in cold radon water. This method enables the specialists to increase radon concentrations 2-3-fold using a simple enriching unit.

[A method for preparing air-radon mixtures from radon water by decompression]. / Sposob prigotovleniia vozdushno-radonovykh smesei iz radonovoi vody metodom dekompressii.

The technique has been tested of intensive radon dissolving in water usable for therapeutic procedures. The gas is provided from the soil or ore radon-containing air. The dissolving occurs under artificial growth of radon concentration in gas atmosphere by its compression at the time of mixing with cooled water in accordance with classical laws of gas distribution between liquid and gas phases in closed space. Practical utilization of the above method allows preparation of therapeutic water media without radium preparations and more effective use of radon produced in radon laboratories, thus significantly reducing radon waste and environment pollution.

[The correction of the functional activity of alveolar macrophages in inducing a primary immune response in influenza]. / Korrektsiia funktsional'noi aktivnosti al'veoliarnykh makrofagov v induktsii pervichnogo immunnogo otveta pri grippe.

The functional activity of alveolar macrophages obtained from mice, both healthy and infected with influenza virus A/Aichi 2/68 (H3N2), as manifested by their capacity to initiate the development of primary immune response to sheep red blood cells and Escherichia coli lipopolysaccharide after the transfer of these macrophages to intact syngeneic recipients was studied. The capacity of alveolar macrophages to perform antigen-presenting functions in the induction of humoral immune response was shown, and at the same time the development of experimental influenza infection was found to essentially decrease these properties. The injection of the immunomodulating agent diuciphon into experimental mice somewhat enhanced the immune response after the syngeneic transfer of alveolar macrophages from infected mice to intact recipients.

[Use of the liposomal forms of a terrilytin preparation for the lysis of experimental thrombi]. / Ispol'zovanie liposomal'nykh form preparata terrilitina dlia lizisa éksperimental'nykh trombov.

Thrombolytic activity of liposomal terrilytin forms has been experimentally studied. Liposomal terrilytin form (50-280 PU/kg) was administered to rabbits 24 hours after the experimental induction of femoral thrombi. In 43.75% of cases complete lysis of the thrombi was noted, in 37.5% of cases different stages of the lysis of wall thrombi were observed and in 18.75% of cases the thrombi remained. In the control experiments the thrombi remained in 75% of cases, while in 25% of cases spontaneous lysis of the thrombi occurred. Statistically significant hemostasis changes gave evidence of the decrease in the blood clotting activity after oral administration of a liposomal terrilytin form. It has become possible to achieve thrombolytic effect using lower doses of orally administered liposomal terrilytin form, which is both therapeutically and economically important.
