ABSTRACT
The paper deals with the influence of the adenovirus (Ad) and Epstein-Barr virus (EBV) on functional activity of lymphocytes, in particular, the production of alpha- and gamma-interferons, tumor necrosis factor (TNF) in conditions of mono- or double infection of B- and T-phenotype (CEM) lymphoblastoid cells. It is shown, that Ad, EBV or both viruses induce high enough levels of interferon on both lines of cells and in control epithelial cells. The lymphoblastoid cells infected by viruses deep ability to synthesize alpha- and gamma-interferons under the influence of the corresponding inducers (Newcastle disease virus and hemagglutinine). Nevertheless, the levels of their formation are not high. Rather high parameters of activity of the tumor necrosis factor (TNF) were revealed during a day in the initial B95-8 cells and superinfected Ad after the effect of LPS of E. coli. Their activity in CEM cells also did not depend on the infection type.

By the method of tissue culture, it is established that the capron threads stained by brilliant green, coated with the chemosorbed substances on the base of titanium alkoxides, polyalkylhydridsiloxanes and polyorganilsiloxanes have no histotoxic properties and can be used in microsurgical practice.
