ALKYLRESORCINOLS INFLUENCE ON HOMOSERINE LACTONES PERCEPTION IN THE LUMINESCENCE INDUCTION TEST OF THE ESCHERICHIA COLI LUXR + LUXI_LUXCDABE [№ 6 ' 2012]
On model of a reporter luminescent strain E. coli JLD271, pAL103; luxR+ luxI_luxCDABE (A. Lindsay, B. M. Ahmer, 2005) we investigated influence of dormant state inductors — alkylresorcinols (AR) on bacterial perception of cell-density mediators — homoserine lactones (HSL). Reaction of bacteria to HSL didn't change by joint addition of AR, while use of preliminary processing mode by AR reduced the following luminescent induction by HSL in a concentration-dependent manner. Dependence of bioluminescence repression from AR molecules alkyl radical's length and hydrophobicity, also as suppression of a cellular metabolism are shown.

СORRECTION OF RESULTS OF BIOLUMINESCENCT ANALYSIS IN VIEW OF OPTICAL PROPERTIES OF OBSERVED CARBONIC NANOMATERIALS [№ 6 ' 2010]
A mathematical tool has been developed aiming at correction of results of bioluminescent analysis in view of optical properties of the examined samples. With its assistance a specialized computer application was created to quantitatively evaluate bioluminescence of bacteria existing in faintly clear (colored and/or blurred) environment. Use of this application while evaluating biotoxicity of carbonic nanomaterials allowed eliminating distorting effect of optical properties of observed compounds on the results of carried out analysis.

ALKYLXYBENZOLS INFLUENCE ON FUNCTIONAL ACTIVITY OF FC-FRAGMENTS OF ANTIBODIES [№ 12 ' 2009]
Ability of alkylxybenzols (AOB) change the functional activity of Fc-fragments of antibodies responsible for the initiation of the classical wais of complement activation is studied in the system of complementdependent hemolysis. It is determined that in such system C6-AOB and C12-AOB but not in C1-AOB and C3-AOB have their own haemolytic effect in high concentrations. At lower concentrations C6-AOB and C12-AOB influence on the kinetic characteristics of reaction of complementdependent hemolysis causing a time increase of lysis coming of 50% target cells without changing of lytic reaction speed.

INFLUENCE OF THROMBOCYTE CATION ALBUMEN ON BIOLUMINESCENCE AND VIABILITY OF RECOMBINANT STRAIN ESCHERICHIA COLI WITH CLONED LUX-OPERON PHOTOBACTERIUM LEIOGNATHI [№ 2 ' 2009]
High sensibility of bioluminescence response of recombinant strain E.coli K 12 TG1 with cloned luxCDABE with gene P.leiognathi 54D10 to the influence of thrombocyte cation albumen (TCA) is established in this article. Determined for TCA quantities IC50, corresponding to 50-percent inhibition of luminescence intensity from starting level form in the same system 3,3-7,1 mkg/ml. It is shown that concentration dependences of bioluminescence suppression at the presence of TCA are inferior a lot to the development true bactericidal effect regarding to used bacterial cell-targets. As one of the possible reasons of such phenomenon it was named direct abscopal influence of TCA on enzymatic system of luminescence generation.

THE VARIANCE ANALYSIS OF THE ALKYL PHENYL ALCOHOL EFFECTS IN THE SYSTEMS "FERMENT-SUSTRATUM"AND "ANTIGEN- ANTIBODY" [№ 12 ' 2008]
The significance of the alkyl phenyl alcohol (APA) impact on the reaction components "Ferment-Substratum" and "Antigen-Antibody" was quantitatively assessed through the variance analysis method. It was found that in these two-component systems the C1-APA acted both through modification of functional activities of the protein molecules and alterations of the substratum characteristics and, in particular, antigens. On the other hand, most significant action mechanism of the C6-APA was found to be its direct modifying impact on the ferment activity and antigen-binding capabilities of the antibodies.
