[Susceptibility to antimicrobial agents of bacteria isolated from pregnant, postpartum women, and newborns from zones with high irradiation risk].

Susceptibility of 350 strains of staphylococci, isolated from pregnant women, puerperal and newborns and of 170 strains, isolated from obstetrical hospital environment at the region with high risk of radiation after accident was determined. The tested bacterial strains were the following: 56--Staphylococcus aureus, 152--S. epidermidis, 142--S.

[Liposome-incorporated interferon. The design of liposomal interferon].

To develop bound interferon, purified phospholipids (PL), obtained from waste products of soy-bean oil production, were chosen as lipid carries. The method for the development of the liposomal interferon complex was proposed. As shown in this study, with regard to the composition of the most significant PL fractions the carrier obtained from waste products of soy-bean processing proved to be more acceptable for humans than egg-yolk PL, traditionally used in practical liposomology.

[Interferon incorporated into liposomes. A method for the design of homologous and heterologous liposomes and the control of their in-vivo permeability].

The specific features of the fatty acid composition of phospholipid carriers obtained from raw materials of vegetable and animal origin were studied. Differences in the enrichment of phospholipids of different origin with polyene fatty acids were shown. The method for obtaining fluoroliposomes incorporating such components as phospholipids of mouse organs, egg yolk, etc.

[Heterogenetic antigens of Yersinia pseudotuberculosis in human erythrocytes and organs].

The study of the antigenic relationship between Y. pseudotuberculosis in red blood cells and different highly vulnerable tissues of the human body (in the liver, the spleen, the kidneys, the lymph nodes, the intestine) has been carried out; as a result, the presence of heterogeneous substances has been shown. Y.

[Change in the nonesterified fatty acid makeup of Shigella flexneri No. 15172 type 3a in the process of passage on developing chick embryos].

Composition of nonesterified fatty acids/NEFAj from Shigella Flexneri was similar to that from other Gram-negative bacteria of the enteritic group. At the same time, NEFA of the dysenteric bacteria contained comparatively high amount of branched and cyclopropane-bearing fatty acids. Adaptation of Shigella Flexneri in the medium of developing chicken embryo led to a distinct increase in total NEFA content as well as of cyclopropane-bearing and saturated fatty acids in the bacteria and to a decrease in content of branched-chain and unsaturated fatty acids.
