[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.

[Pharmacoeconomic model of the use of rifabutin in new cases of pulmonary tuberculosis].

The formalized procedures to commensurate the results and expenditures were used to make a comprehensive evaluation of the clinical efficiency and economical expediency of purposeful application of rifabutin in new cases of disseminated and destructive pulmonary tuberculosis.

[Efficacy of arbidol in prophylaxis and treatment of acute respiratory viral infections in servicemen].

The authors present the results of study of arbidolum therapeutic-and-prophylactic effectiveness in acute respiratory viral infections (ARVI) under conditions of military staff with determination of economic expediency. Coefficient of effectiveness of arbidolum prophylactic use was 25% and efficiency index--1.33.

[Pharmacoeconomic aspects of use of structum in osteoarthrosis].

Aim: To study cost-effect efficiency of structum in patients with knee and hip joint osteoarthrosis (OA) in a multicenter trial.

Material And Methods: The trial enrolled 192 patients with OA. 110 patients had knee joint OA and 82 patients hip joint OA.

[Whitefish: a new mechanism of reproductive isolation].

Taxonoprint (a modification of DNA restrictase analysis) allows to distinguish sympatric species, that do not mate or produce hybrid offspring that are sterile or not viable. It is shown that taxonoprints of whitefish are very similar of identical. Sympatric whitefish are continuing to be separate despite they easily mate in experiments and in nature (up to 30% of individuals in nature are hybrids) and hybrids offspring have some features of heterosis.
