[Development of the quantitative immunochromatography tests for somatic deasease markers detection].

The purpose of work was creation of quantative immunochromatographic tests (ICT) for measuring concentrations of the marker substance associated with somatic diseases: immunoglobulin E (IgE), C-reactive protein (CRP) and fibrin D-dimer in blood serum (plasma), which is carried out with the help of videodigital analyzers of domestic development "Reflecom" and "Zondaj". ICT were designed in sandwich-format, using colloid gold and monoclonal antibodies. It is shown, that calibration curves received with the help of ICTand devices of videodigital registration, are well approximated by exponential dependence Y = Aexp(-x/B)+y0, where Y--device readings, x--analytes concentration, A, B, y0--constants.

[Development of a venous-valve biological prosthetic graft for treatment of valvular insufficiency].

The present study was undertaken to experimentally assess a possibility of creating a xenogeneic biological venous-valve prosthetic graft using the vv. saphena medialis of the cattle. The findings obtained in the amino-acid analysis demonstrated that diglycidyl ether ofethylene glycol (DEEG) is an efficient suturing agent for xenoveins.
