[Clinical trials of the new skin test Diaskintest for the diagnosis of tuberculosis].

A new reagent for a skin test given the name Diaskintest has been designed for the screening diagnosis of tuberculosis and preclinical and clinical trials conducted. Preclinical trials were carried out on 315 laboratory animals (guinea-pigs, albino mice). The reagent Diaskintest was ascertained to be nontoxic, to have no sensitizing properties, to be safe and specific, and to induce no positive reactions in BCG-vaccinated animals and healthy guinea-pigs.

[Satellite DNA restriction site variability as a molecular basis of taxonoprint method: evidence from the study of Caucasian rock lizards].

The restriction site distribution in satellite DNA of 17 Caucasian rock lizard species of the genus Lacerta (Darevskia gen. nov.), (Squamata, Lacertidae) was analyzed.

[Reticulate evolution of parthenogenetic species of the Lacertidae rock lizards: inheritance of CLsat tandem repeats and anonymous RAPD markers].

The genetic relatedness of several bisexual and of four unisexual "Lacerta saxicola complex" lizards was studied, using monomer sequences of the complex-specific CLsat tandem repeats and anonymous RAPD markers. Genomes of parthenospecies were shown to include different satellite monomers. The structure of each such monomer is specific for a certain pair of bisexual species.
