[Increase in the number of antibody producing cells during combined cultivation of lymph node cells from immunized animals with intact bone marrow cells].

An increase in the amount of direct and indirect plaque-forming cells in mixed cultures of lymph node cells from mice primed and challenged with sheep red blood cells with syngenic and allogenic bone marrow cells from intact donors was observed. The amount of plaque-forming cells in mixed cultures reached the maximum level in 9--11 hours of cultivation and then fell to the initial level. The authors believe that in mixed cultures of lymph node cells from immune mice and bone marrow cells from intact donors there occurs an involvement into the antibody synthesis of new cells of one of the two cell populations cultured.

[Protective efficacy of combined administration of the multicomponent vaccine and the immunomodulator myelopid in experimental infections in mice].

The influence of myelopid (MP) on the protective activity of polycomponent vaccine VP-4 prepared from the antigens of opportunistic bacteria was studied on experimental infections of mice, caused by Klebsiella pneumoniae, Salmonella typhimurium and Staphylococcus aureus. In staphylococcal and Klebsiella infections the joint administration of vaccine VP-4 and MP produced more pronounced protective effect than each of these preparations, introduced alone. The protective action of vaccine VP-4 was specially enforced by MP in cases of local staphylococcal infection. Recommendations on the joint use of two or more immunomodulating agents are possible only on the basis of the experimental substantiation of their effect in definite infections.

[The effect of myelopid on antibody formation in gamma-irradiated animals].

The effect of a new immunocorrecting preparation, Myelopid, on the antibody-forming cell content of mouse spleen after gamma-irradiation (1-3 Gy) has been investigated. The preparation administered after immunization of mice with sheep erythrocytes increases the number of antibody-forming cells in the spleen, the effect being a function of radiation dose and time interval between the exposure and immunization. The preparation is ineffective when delivered after irradiation, but prior to immunization.
