[The effect of millimeter-band radiation of nonthermal intensity on sensitivity of Staphylococcus to various antibiotics].
In the presence of subbactericide concentrations of active antibiotics the irradiation could result in both further suppression of bacteria growth and its stimulation, and weak changes are observed at further increase of this period up to 60 min.

The antimicrobial spectrum correlated with the membranotropic properties of the compounds and it was suggested that the target of the antimicrobial action of the screened phenols was the bacterial cell cytoplasmic membrane.
[Lysis of bacterial protoplasts and spheroplasts and suppression of their dehydrogenase activity by neotehomycin].
Resistance of E. coli to neotelomycin must be associated not with the presence of the antibiotic non-permeable cell wall but the peculiar properties of the membrane cytoplasm.

[Teichoic acid content in the cell wall of Actinomyces rimosus LST-118 in the process of ontogeny].
It was found that the content of teichoic acid decreased 2 times by the end of development of Act.
[Action of neotelomycin derivatives on bacillus magaterium cells].
The triptophane structure was probably not only the center actively affecting the cell but also the factor that provided the antibiotic molecule with conformation most favourable for the action of the free amino group on the membrane structures.

Combination of the antioxidant and antimicrobial properties in fenozan was likely to provide its satisfactory therapeutic effect in the treatment of burn wounds.
[Optical density changes in bacterial protoplast suspensions exposed to membrane-active antibiotics].
The observed increasing of the suspension OD must be due to the fact that the membrane active antibiotics induced a decrease in the osmotic stability of the protoplasts not sufficient for their lysis.

It is shown that the neutral derivatives and the derivative with acidic properties showed a considerable lytic activity when they were incubated with the protoplasts of Micrococcus lysodeikticus, Bacillus megaterium and Bacillus subtilis, and preserved a certain membranotropic level.
