[Effect of interferonogenic molecular complex of yeast RNA--tilorone on DNA, RNA and protein synthesis in vitro]. / Vplyv interferonohennoho molekuliarnoho kompleksu drizhdzhova RNK--tyloron na syntez DNK, RNK ta bilka in vitro.

In the experiments in vitro using the primary mononuclear cells (MNC) culture of the human peripheral blood the influence of interferonogenic yeast RNA-tilorone molecular complex on the DNA, RNA and protein synthesis was studied. The complex was shown to inhibit the insertion of 3H-thymidine, 3H-uridine and 3H-leucine into DNA, RNA and protein of MNC total pool (by 13, 1 and 40% respectively); that was practically conformed with this synthesis inhibition upon to a natural origin polynucleotide interferon inducers--lariphan (9, 0 and 57% respectively) and ridostin (9, 0 and 56% respectively) action, and at the same time rather less than poly(I)-poly(C) (14, 5 and 62% respectively). In the case of preliminary cell stimulation by the mitogen PHA the complex revealed comitogenic action at a concentration 25 micrograms/ml, that corresponded to optimal for interferonogenesis; the increase of the doses till 100-1000 micrograms/ml lead to in the reversal effect. To proceed from mutual relation between interferonogen preparations influence on the mentioned synthesis and their cytotoxicity the conclusion was about made the complex promising usage as an interferon inducer both in vitro and in vivo conditions.

[The depression of the reproduction of the human immunodeficiency virus by the use of Bogomolets antireticular cytotoxic serum]. / Pryhnichennia reproduktsiï virusu imunodefitsytu liudyny za dopomohoiu antyretykuliarnoï tsytotoksychnoï syrovatky Bohomol'tsia.

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.
