[Specific hyposensitization of microbial allergy by using a synthetic artificial polyelectrolyte].

In this work the effectiveness of complex immunotherapy, including specific inhalation hyposensitization with the introduction of artificial synthetic polyelectrolite, was studied. Specific allergen produced a good effect (75%) in the inhalation hyposensitization of hemophilic allergy. The intramuscular injection of artificial synthetic polyelectrolite, made in addition to the inhalation of allergen, produced a better desensitizing effect than the separate administration of allergen or polyelectrolite. The multiple administration of polyelectrolite produced a desensitizing effect on allergic reactions of type I with the tendency towards the decrease of reactions of type IV. Good prospects for the development of methods for special treatment with homologous allergen in combination with NA-5 in cases of microbial sensitization under the control of immunocompetent cells were shown.

[Effect of detergent and glycerin on the efficacy of nasal immunotherapy with allergens and on the level of the lymphocyte subpopulation in the organs of local immunity].

Experimental mixed allergy to staphylococcal antigens in guinea pigs was treated by the intranasal administration of a staphylococcal allergen with a surfactant or glycerin added. The treatment was found to produce a hyposensitizing effect with respect to immediate and delayed hypersensitivity. The addition of glycerine enhanced this effect. At the same time the level of T-lymphocytes in the lungs and the lymph nodes of the respiratory tract returned to normal. Detergent used at a concentration of 2% abolished the hyposensitizing effect of the allergen, stimulated T-lymphocytes in the lymph nodes of the respiratory tract and the lungs; the number of T-suppressors decreased.

[Electron microscopy of Haemophilus influenzae].

The electron microscopic study of H. influenzae standard strains, serovar b, in the capsular and noncapsular forms has revealed the pronounced pleomorphism of these organisms in successive generations.

[Sensitizing properties of soluble Haemophilus influenzae antigens].

The sensitizing properties of different doses of the antigenic preparation obtained from H. influenzae by ultrasonic treatment have been studied. Small doses of the antigen have been found to induce immunoallergic transformations of type IV in sensitized guinea pigs. A considerable increase in the sensitizing dose of the antigen has been found to lead to the appearance of allergic reactions of type I. The regularities of the development of allergy to H. influenzae are discussed.

[Lymphocyte subpopulations in sensitization and specific immunotherapy in an experiment. Lymphocyte subpopulations in sensitization to staphylococci, Artemisia pollen and their combinations].

The distribution of T- and B-lymphocytes in the body of guinea pigs was studied in different groups of the animals. As shown in this study, in delayed hypersensitivity to staphylococci the number of PE- and E-rosette-forming cells increased in the blood, the spleen, and the lymph nodes and decreased in the thymus; the number of EA- and EAC-rosette-forming cells decreased in the bone marrow and the spleen, the number of T gamma-suppressors decreased in the bone marrow and the distant lymph node. Immediate hypersensitivity to tarragon pollen induced the general increase of the content of T- and B-lymphocytes; the number of T gamma-cells decreased in the thymus, the bone marrow, and the lymph nodes and increased in the spleen. The characteristic features of combined microbial-pollen sensitization were the high content of B-cells in all lymphoid organs (except the thymus), a low level of T-lymphocytes in the blood and the peripheral lymphoid organs, the decreased number of T gamma-cells in most of the immunogenetic organs.

[Formation of pollen-induced allergy in guinea pigs after specific immunotherapy with a bacterial allergen].

The investigation was aimed at elucidating the process of the development of allergy to exoallergens (e.g., to linear-leaf wormwood pollen) in the body after desensitization by specific immunotherapy (SIT) with heterologous (staphylococcal) allergen. The study revealed that in staphylococcal allergy the subsequent development of pollen sensitization occurred with greater intensity, and SIT was found to exert no influence on this process. For the first time pollen allergy was found to produce an unfavorable effect on the quality and effectiveness of SIT with heterologous staphylococcal allergen, this effect consisting in the acceleration and intensification of the process leading to the recovery of sensitization to staphylococci. The importance of measures for limiting contacts with heterologous allergens and their elimination during SIT is emphasized.

[Comparative evaluation of the diagnostic effectiveness of staphylococcal allergens of different manufacture in bronchospastic reactions of sensitized lungs].

With allergic immediate hypersensitivity test to the antigens of Staphylococcus aureus strain Wood 46 specific bronchospastic reactions were simulated in the lungs of guinea pigs by means of two allergens: commercial allergen manufactured in Czechoslovakia and staphyloallergen prepared by ultrasonic treatment under laboratory conditions at the Alma-Ata Research Institute of Epidemiology, Microbiology and Infectious diseases (USSR). Allergens prepared at the Kazan Research Institute of Epidemiology and Microbiology (USSR) and in Bulgaria produced no reactions.

[Bronchospasm induction by mediators of antigen-specific stimulated lymphoid cells].

The action of lymphokines, soluble mediators of cell-mediated immunity was studied on isolated lungs of guinea-pigs. Antigen-specific antigens were shown to have bronchospastic activity as regards sensitized and nonsensitized lungs. The bronchospastic effect is not mediated by histamine or by other chemical bronchoconstrictors, and is not linked with activity of leukocyte migration inhibition factor.

[Comparative immunochemical and immunoallergic characteristics of staphylococci of different pathogenicity. II. Diagnostic value of extracts of Staphylococcus aureus and Staphylococcus epidermidis in delayed type allergic reactions].

A total of 20 different allergens extracted from various staphylococcal strains were studied in the delayed hypersensitivity reactions in experiments on guinea-pigs. The most intensive dermatoallergic reactions were observed after the injection of the cytoplasmic fraction, acidic and alkaline extracts; reactions to the allergen of Ando-Verzhikovsky were less pronounced. The cytoplasmic fraction and the allergen of ando-Verzhikovsky were more active in the reaction of leukocyte migration inhibition in the blood. Both common and individual allergenic components were detected. No correlation between the results of the immunochemical and allergological studies of staphylococcal extracts was revealed.

[Comparative immunochemical and immunoallergologic characteristics of staphylococci varying in pathogenicity. I. Immunochemical characteristics of the antigenic composition of S. aureus and S. epidermidis].

Chemical extracts and fractions prepared from pathogenic and nonpathogenic staphylococcal strains were studied with immunodiffusion. Antigens were detected reacting with both homologous and heterologous antisera against the intact coccal cells. The allergens obtained by acidic and alkaline extraction were highly active antigens. The preparation of S. epidermidis obtained by the method of Ando-Verzhikovsky had the lowest antigen level.

[T- and B-lymphocytes and an analysis of the specific reactivity in experimental brucellosis].

There was an increase of a relative and absolute T-lymphocytes content and a considerable reduction of B-lymphocytes in the peripheral blood of guinea pigs infected with a high doses of brucella of vaccine strain 19-BA. There proved to be no correlation between the number of T-lymphocytes in the blood and the intensity of Burnet's test. The content of B-lymphocytes was compared with different antituberculosis antibodies in the blood serum of the infected animals.

[Specific experimental therapy in sensitization to group A streptococci].

A model of delayed hypersensitivity to Streptococcus hemolyticus, group A, were obtained in guinea pigs and rabbits. Studies of spontaneous changes of the immuno-allergic reactivity revealed that after a month of sensitization there developed delayed hypersensitivity only; according to the results of late skin tests it lasted not less than 6 months (the duration of investigation). The delayed hypersensitivity component began to manifest itself in 2 1/2 to 3 months and increased later on. Specific hyposensitization was performed with streptococcus allergens differing by physico-chemical conditions, i.e. the corpuscula allergen, the one that was lysed by ultrasonic waves, and Ando-Verzhikovsky's allergen. The latter had the most intensive hyposensitizing features. Specific hyposensitization was more demonstrative after the intracutaneous long-term course injections of threshold doses. Administration of subthreshold doses, as well as subcutaneous or intravenous injections of the allergen, was ineffective.
