title: [Effect of quinolaline di-N-oxide derivatives on the DNAse and plasmocoagulase of Staphylococcus aureus].
abstract: The effect of the di-N-oxide quinoxaline on the activity and biosynthesis of DNA-ase and plasmocoagulating properties of the Staphylococcus aureus, strain Zhaev, was studied. The highest action in respect to DNA-ase of the Staphylococcus is shown to display dioxydine (1,4-di-N-oxide of 2,3-dioxymethylquinoxaline). Under its effect there takes place a significant fall of the DNA-ase activity and the plasmocoagulating properties of the staphylococcus. In cultures treated with dioxydine or its biologically active analogues the ability to biosynthetize DNA-ase with subsequent cultivationon on a medium containing no compounds is not restored. A possible mechanism of action produced by the study drugs is suggested.
