[Antioxidant effect of novel probucol analogs and their combinations with alpha-tocopherol].

The antioxidant and antiradical activities of sulfur containing phenols which are analogues of probucol in comparison with alpha-tocopherol and BHT were tested using initiated methyl oleate oxidation model. The antioxidant effect linearly increased with increasing concentration of phenols. The ability of investigated phenols to destroy and reduced accumulation of hydroperoxides is revealed.

[The use of proteases for enhancing the sensitivity of detecting ABO system antigens by an absorption-elution reaction in blood stains].

The sensitivity of the absorption-elution test (AET) for the detection of A, B, and H antigens in blood traces can be appreciably increased by using serologically active proteases at different stages of the test. A sensitive AET modification is developed, detecting group antigens in far lesser amounts of the material than by routine AET without proteases. A higher sensitivity of the antigen-antibody reaction between enzyme-treated erythrocytes and tested blood traces permits the use of standard group-specific sera less active than usually; the actually solves the problem of deficit of the sera fit for this test.
