[Hemo- and immunostimulating effect of an extract from blood cells of the Central Asian tortoise]. / Gemo- i immunostimuliruiushchii éffekt ékstrakta kletok krovi sredneaziatskoi cherepakhi.

Radiotherapeutic efficacious of the compounds from major organs and tissues of Central Asian tortoise--the animal known for its unique radioresistance, has been checked up. Along with the so well-known compounds as the plasma ones, tortoise spleen extracts (TSE) and the ones from the liver of adult animals and embryos, extracts from kidneys and muscles have been shown to increase the survivability rate of irradiated rats and mice. The compound, that called "Tortezin" shows the highest blood cell cytosol effect. The specific activity and the output are 4 and 12 times higher, than the ones of TSE, respectively. Dose increase factor (DIF) reaches as far as 1.41. The compound possesses considerable immunostimulating activity. The detailed physico-chemical characteristics of the compound, quite sufficient for its identification has been made.

[Effect of freon-114B2 (1,2-dibromotetrafluoroethane) on the seasonal rhythm of energy activity in rat liver mitochondria]. / Vliianie freona 114B2 (1,2-dibromtetraftoretana) na sezonnyi ritm energeticheskoi aktivnosti mitokhondrii pecheni krys.

In the experiments with white rats it was found, that the inhalation of freon 114B2 at CL16, CL50, CL84 levels caused the changes in seasonal values of the energy activity in mitochondria. The action of the freon 114B2 caused disturbances in regulation of the mitochondria activity and desynchronization of seasonal rhythms of their energy activity.
