[The production of the tumor necrosis factor in an experimental staphylococcal infection].

The paper deals with the study of production of tumour necrosis factor (TNF), the key mediator of inflammation and immune responses of the organism, under experimental and staphylococcus infection (Staphylococcus aureus, st. 209) on mice of C57B16 line. It is established that staphylococcus infection of animals lead to TNF induction. Dynamics of this cytokinin synthesis by peritoneal macrophages and splenocytes under the infection of mice with S. aureus in different doses differed in time and as to absolute values. In animals infected by staphylococcus in a dose of LD30 the TNF production was high as compared to the control for 72 h after the infection and was normalized on the 4-6th day of the experiment. When using staphylococcus in a dose of LD50, spontaneous production of this cytokinin was higher than that in the control for the whole period of observation.

[The depression of the reproduction of the human immunodeficiency virus by the use of Bogomolets antireticular cytotoxic serum].

The action of the Bogomolets' antireticular cytotoxic serum (ACS) as a HIV-1 reproduction inhibitor was studied on the model of human lymphoblastoid cell line MT-4/BRU (acute infection). The HIV-1 reproduction inhibition was estimated according to cell protection level for virus cytopathic action and p24 antigen level in the cultural media. The both tests data on ACS usage in dilutions 1:160-1:640 prove that the virus inhibition effect which may be compared with anti-HIV action of the well-known agent, azidothymidine, was observed. At this dilutions range ACS is devoid of the cell toxicity. The conclusion about perspectivity of ACS usage in the AIDS complex therapy was drawn.
