[Morphological alterations in animal organs after the injection of acellular pertussis vaccine with immunomodulator]. / Morfologicheskie izmeneniia v organakh zhivotnykh posle vvedeniia beskletochnoi kokliushnoi vaktsiny s immunomoduliatorom.

Toxic properties of acellular pertussis vaccine (APV) and morphological changes in white mice in response to intramuscular injection of APV (without or with immunomodulator glucosaminylmuramyl dipeptide-GMDP) were under study. APV used in these experiments was developed at the Mechnikov Research Institute for Vaccines and Sera (the Russian Acad. Med. Sci.) on the basis of Bordetella pertussis cultures in synthetic fluid culture media. In experiments on acute and chronic toxicity of APV (without GMDP) increased tissue immunity reactions in spleen, thymus, liver, lungs and intestinal wall was detected. There was no difference in immunomorphological reactions in mice receiving APV with different doses of GMDP, but some difference was observed in time dynamics of tissue immunity reactions. A small dose of GMDP should be preferred (0.0001 microgram) which results in gradual growth of tissue immunity reactions less pronounced toxic reactions caused be the APV injection.

[The indices of interleukin 1, 2 and 4 production and the specific antibody titers in mice with an opposite sensitivity to staphylococcal infection]. / Pokazateli produktsii interleikinov 1, 2 i 4 i titry spetsificheskikh antitel u myshei s oppozitnoi chuvstvitel'nost'iu k stafilokokkovoi infektsii.

The data on a high level of interleukin production in mice, resistant to staphylococcal infection (CBA), in comparison with that in mice, sensitive to this infection (C3HA), are presented. The production of interleukin 1 in intact and infected mice of different strains exhibited no differences between these strains, but its level considerably increased after the inoculation of the animals. A the same time differences in the synthesis of IgM and IgG1 in intact and infected mice of different strains were noted.
