[Effect of wheat germ agglutinin on acholeplasma--the pathogen of phytomycoplasmosis].

Introduction of wheat germ agglutinin (WGA) to cultural medium of pale green dwarf agent of wheat Acholeplasma laidlawii var. granulum str. 118 gives rise to pleiotropic responses of acholeplasma: activation of growth process, an increase of common protein in comparison with control, a decrease of hemagglutinating activity which results in a decrease of the adhesion properties of pathogen.

[Atomic force microscopy detection of serological markers of viral hepatites B and C].

The aim of the study was to demonstrate the possibility of detection of serological markers, containing the hepatitis B surface antigen (HBsAg) and hepatitis C virus core-antigen (HCVcoreAg) in human serum, by use of a new atomic force microscopy (AFM)-based nanotechnological approach. In this study, the immobilization on AFM-chip of antibodies against the hepatitis B virus surface antigen (anti-HBsAg) as well as the antibodies against the hepatitis C virus core antigen (anti-HCVcoreAg) was performed. It was shown that such approach enables to detect: HBsAg, HCVcoreAg and the viral fragments containing these antigens in the serum.

[Antineoplastic properties of extracellular fructoso-1,6-bisphosphatase of Bacillus subtilis 668 and preparation isolated from cultural liquids of Bacillus subtilis 7025].

It was shown for the first time that extracellular FBPase of B. subtilis 668 like the preparation obtained from culture liquid of B. subtilis B 7025 displays citotoxicity activity in respect of tumor cells of sarcoma 37 in vitro.

[Comparative investigation of fructosobisphosphatases of Bacillus subtilis and pale-green dwarfism pathogens of cereals in the reaction of double diffusion in gel according to Ouchterlony].

Serological properties of fructosobisphosphatases (FBPases) of Bacillus subtilis 668 and PGD agent of cereals--the mollicute Acholplasma laidlawii var. granulum st. 118 (Alg 118) were studied in a comparative aspect with the help of the reaction of double diffusion in gel according to Ouchterlony.

[A comparative evaluation of detection of antibodies to hepatitis C virus in different immunoassay test system and verification tests].

Control tests and subsequent comparative analysis of their results related with the detection of anti-hepatitis C virus (anti-HCV) by different ELISA systems were made at a laboratory of the "Vector-Best" Company, Novosibirsk (A), a clinical diagnostic laboratory of Infection Clinical Hospital No. 1, No. 1 (B), and at a laboratory of chronic viral infections of Andjaparidze Institute of Viral Drugs of the Russian Academy of Medical Sciences (C).
