ABSTRACT
The proposed agent for the woven materials impregnation gives them antibacterial properties concerning gram-negative and gram-positive microflora, and have also the fungicidal activity. It high effectiveness testifies the vast resources of an agent in the treatment and prophylaxis of surgical pyo-inflammatory infection.

The conjugate analysis of the address map, the density chart and the map of the density field of tetanus morbidity with the soil map has revealed that this morbidity is linked with the properties of the soil. The map of the density field has proved to be most suitable for such analysis. Morbidity is unevenly distributed over the territory. Its highest level is observed in regions with neutral or almost neutral soils. Regions with soils having acidic or alkaline properties are characterized by low morbidity levels. The dependence of morbidity levels on the proportional distribution of soils with different properties has been determined. These data may be used for the prognosis of morbidity on territories with soils differing in their acidic and alkaline properties.

The composition of the fatty acid profiles of Cl. perfringens type A, grown on media with initial pH values from 5.5 to 9.0, was determined by the method of gas-liquid chromatography. The fatty acid profiles are stabilized in 18- to 24-h cultures. Hydrogen ions stimulate the synthesis of cyclopropane carboxylic fatty acids and "desaturase" activity; hydroxyl ions inhibit these processes. The content of saturated fatty acids in the bacteria is regulated by the initial acid-alkaline conditions of the medium. An increase in biomass accumulation under the influence of hydroxyl ions is coupled with a decrease in the energy supply of the bacteria. Possible mechanisms of the development of resistance to hydrogen and hydroxyl ions during the cultivation of Clostridia on a period growth medium are discussed.
