[The influence of the penetrating cryoprotectors on protein synthesis in the cell-free system of the rat liver].

The influence of the penetrating cryoprotector and Mg2+ ions on the protein-synthesizing activity of postmitochondrial supernantant of the rat liver as well as on aminoacylation processes has been investigated. The addition of the penetrating cryoprotectors--ethylene glycol and DMSO--resulted in the concentration-dependant reversible inhibition of the protein biosynthesis and aminoacylation reaction in the cell-free system. These cryoprotectors at low concentrations intensified the stimulating effect of Mg2+ on the cumulative protein synthesis in the cell-free system.

[The distribution of haptoglobin phenotypes among the population of Ukraine].

The results of investigation of haptoglobin (Hp) types in 596 donor blood samples in some towns of Ukraine (Dnepropetrovsk, Kharkov, Odessa, Kiev, Uzhgorod, Zhitomir) are presented. Three normal Hp types (Hp1-1, Hp2-1 and Hp2-2) have been found. The reliable interpopulation differences in the Hp types frequency were not found.
