[Construction of the immunoenzyme test system "IFA-AtEBV-Strip" for detecting antibodies of the Epstein-Barr virus].

The first home immunoenzyme test-system for finding antibodies to the Epstein-Barr virus (EBV) has been created. The test-system laboratory prototype was called "IFA-AtEBV-strip". Production technology has been developed for specific components of immunoenzyme test system and all the analysis stage conditions have been optimized: the antigen sorption on plates, its interaction with the studied serum, finding out of the formed immune complex.

Therapeutical effect of modified adamantane copolymer compounds: study of molecular mechanisms.

Copolymers of N-polyvinylpyrrolidone-acrylic acid (AB-1) and adamantane derivatives are known to possess marked antiviral activity in in vitro and in ovo models. Among the constructed preparations of AB-1 modified by adamantane derivatives some, especially AB-4 (modified by deitiforin), were found to show more extended antiviral activity and to inhibit markedly virus reproduction in susceptible permissive cell cultures and chicken embryos. In AB-4 treated cells and allantoic sacs, virus titers (influenza virus, herpes virus, and HIV) and virus antigen concentration were decreased.

[Detoxicating function of the placenta of childbearing women from ecologically unfavorable regions of the Ukraine].

A study of placental detoxifying activity was undertaken using as the investigated indices glutathione transferase and glutathione reductase activities and total amount of SH-groups and those of low-molecular weight thiols. Malonic dialdehyde content was used as a measure of lipid peroxidation. The placental samples were obtained in several regions of the Ukraine judged either "clean", chemically polluted or radioactively contaminated.

[The production of HIV recombinant proteins and their immunochemical characteristics].

Several Escherichia coli strains producing HIV-specific recombinant proteins including env-1, env-2, and gag sequences have been obtained using different gene engineering techniques. These proteins have been isolated and purified from bacterial lysates by ion exchange chromatography on DEAE-Toyopearl and Streamline-SP columns. Polyacrylamide gel electrophoresis and immunoblotting have been used to prove recombinant proteins purity and to identify them.
