[Phenotypic correction of the immune response by L-tyrosine in mice reacting oppositely to sheep erythrocytes]. / Fenotipicheskaia korrektsiia immunnogo otveta L-tirozinom u myshei, oppozitno reagiruiushchikh na éritrotsity barana.

The possibility of transversion of low-reacting mice into high-reacting ones evaluated by the application of the natural immunostimulators. L-tyrosine and thymic polypeptides (taktivin) were compared by their ability for the phenotypical correction of the immune response of the oppositely reacting mice. It was established that under the application of L-tyrosine to oppositely reacting mice the phenotypical correction of the immune response is possible. The dramatic increase in AFC and the AFC-SI secreting IgM is observed in the mice, low-reacting to SRBC in comparison with the high-reacting lines.

[Chronic nonspecific lung diseases, immunological deficiency and the means of its correction]. / Khronicheskie nespetsificheskie zabolevaniia legkikh, immunologicheskaia nedostatochnost' i puti ee korrektsii.

Ninety-eight patients with different patterns of chronic nonspecific pulmonary diseases (CNPD) were examined for thymus-dependent immunity. The clinical manifestations of T lymphocyte dysfunction included a torpid recurrent inflammatory process in the respiratory system, respiratory viral infections, short-term efficacy of antibacterial drugs. The patients demonstrated a decrease in the number of T lymphocytes, in production of immune interferon, and in secretion of serum thymic humoral factor. Application of tactivin, a new immunomodulator, is an effective approach to correction of the disorders enumerated. The drug has a beneficial effect on inflammatory process, reduces the symptoms of virus-induced intoxication. Administration of repeated tactivin treatment made it possible to shorten the time of repeated tactivin treatment made it possible to shorten the time of staying at hospital, to reduce the frequency of CNPD relapses from 80 to 36% within the period from 2 months to 1.5 years. This permits recommending the drug during resistance to antibiotic therapy.
