[DETERMINATION OF PHYLOGENETIC RELATIONSHIP OF YERSINIA PESTIS STRAINS FROM NATURAL PLAGUE FOCI OF THE CAUCASUS BY MULTI-LO- CUS VNTR-ANALYSIS].

Aim: Determination of the degree of phylogenetic relationship of Yersinia pestis strains iso- lated from the territories of natural foci of plague from the Caucasus using VNTR-typing by 25 loci (MLVA25).

Materials And Methods: 26 strains of Y pestis from Russian natural foci of the Caucasus were used in the study. 25 loci of tandem repeats in Y pestis genome by Le Fleche scheme were used for execution of multi-locus VNTR-analysis.

Preclinical Toxicity of Paclitaxel Biopolymer Formulation.

Background: Poly(hydroxyalkanoates) (PHA) have recently attracted increasing attention due to their biodegradability and high biocompatibility, which makes them suitable for the development of new prolong drug formulations.

Objective: A preclinical toxicology study of paclitaxel biopolymer formulation (PBF) (paclitaxel-loaded poly(3- hydroxybutyrate) (PHB) microparticles) was done in order to assess its safety and to forecast side and toxic effects in a clinical study on patients.

Method: PHB microparticles loaded with antitumor cytostatic drug PTX were obtained by spray-drying method using Nano Spray Dryer B-90.

Effect of mesna on lethal effect and hematological toxicity of taxol and vepeside in mice.

Mesna, an SH-containing uroprotector, attenuates the lethal effect and hematological toxicity of vepeside and taxol, but did not reduce specific activities of the studied cytostatics in mice with transplanted tumors. This selective antitoxic effect of mesna towards vepeside and taxol allows to intensify the anticancer chemotherapy with these highly effective but extremely toxic cytostatics and to improve the efficiency of anticancer therapy.
