[Action of antioxidants on membrane-toxic effects of anticholinesterase agents]. / Vliianie antioksidantov na membranotoksicheskie éffekty antikholinésteraznykh sredstv.

It was found therapeutic-preventive effectiveness of antioxidants (1,4-dihydropyridine derivatives) at poisoning with malathion insecticide. The effect of 1,4-dihydropyridine derivatives can be attributed to a prevention of lipid peroxidation. Antioxidants do not affect the toxicity of 0,0-dimethyl-0-2,2-dichlorvinylphosphate. Thus, antioxidants are pathogenetic drugs for treatment of poisonings with cholinesterase inhibitors.

[Determination of the biological activity of heliomycin by a method of diffusion in agar]. / Opredelenie biologicheskoi aktivnosti geliomitsina metodom diffuzii v agar

A biological method for determination of geliomycin activity using agar diffusion is described. A nutrient medium containing Hottinger broth up to 35 mg per cent of amine nitrogen, 1.5 percent of agar-agar, tap water, pH 7.8 to 8.0 was used. Bacillus subtilis ATCC 6633 served as the test-culture. Geliomycin was dissolved in 0.1 N sodium hydroxide solution.
