[Immobilization of Rhodococcus ruber strain gt1, possessing nitrile hydratase activity, on carbon sorbents].

Rhodococcus ruber strain gtl, possessing nitrile hydratase activity, was immobilized by adsorption on carbon supports differing in structure and porosity. The adsorption capacity of the supports towards cells, the substrate of the nitrile hydratase reaction (acrylonitrile), and the product (acrylamide) was studied. Also, the effect of immobilization and nitrile hydratase activity of bacteria was investigated, and the operational stability of the immobilized biocatalyst was determined.

[Epidemiologic effectivness of poludane in preventing influenza and other acute respiratory diseases in troops].

The epidemiological effectiveness of interferon inductor "Poludanum" produced by "LENS Pharm" (Russia) for prevention of acute respiratory viral infections was tested. The drug was administered among the students of Military Medical Academy (101 students) according to scheme 1: in a nose, 3 drops in each nasal passage two times per week during 4 weeks, with 2 week interruption then the scheme was repeated. The scheme 2 included 3 drops in each nasal passage once a week during 10 weeks (95 students).
