The molecular and cellular mechanisms of the effect of synthetic polyions on immunogenesis are discussed in the paper. The data on the basic properties of polyion immune stimulants and on the mechanisms of cellular reactions to these stimulants were used for constructing artificial antigen-polyion complexes having enhanced immunogenic properties. The vaccinating properties of a number of macromolecular complexes conjugated to bacterial and viral antigens are analyzed. 相似文献

The paper comprises results of studying some demographic and populaton characteristics of the inhabitans of the Samarkand region as a whole and two villages, Karakent and Ishan, inhabited with Uzbeks-Khoja, a special religious-social caste in the past. It is shown that 87.4% of marriages in the Samarkand region are of international character (the information has been obtained on 7995 married couples). The frequency of consanguineous marriages is 11.6%, and among them 40.5% are first-cousin marriages and 39.1% are marriages of remote relatives. The coefficients of inbreeding are rather high among the Jewish, Tajik and Uzbek communities. The coefficient of inbreeding as a whole is F=0.0042 in this region and approaches to the maximal level, characterizing a panmix population. The average size of a family in the villages of Karakent and Ishan is approximately 4.0 persons. The values of reproductive performance, the nature of termination of pregnancies do not differ from those of panmix population. The percentage of intravillage and consanguineous marriages are 56% and 12.5% for the first village, and 25% and 2% for the second one respectively. The coefficient of inbreeding for karakent is F=0.0064, for Ishan--F=0.0014. Taking into consideration the historical development of the two villages and the cumulative data, the conclusion is drawn that Karakent is an isolate on a religious ground whereas Ishan is a disintegrated isolate. 相似文献

The growing pandemia of AIDS, which resulted in about 40,000 AIDS patients and about 3 million infected persons by the end of 1986, demands for the urgent creation of methods for diagnosis, prevention and treatment of the disease. The present paper analyzes the main aspects of AIDS immunobiology, i. e. the molecular genetics of the virus, production of the viral components, construction of kits for immunoenzyme detection of antibodies to the virus, development of confirmatory immunoenzyme assays. The authors discuss the prospects of creating the synthetic antigens of the AIDS virus or producing them on the basis of genetic engineering both for the diagnosis and prophylaxis of the infection. 相似文献

The influence of preparations obtained from oat and wheat seedlings (immunostimulating factors IF-1 and IF-2, respectively) on the natural resistance of mice to P. aeruginosa infection was studied. IF-1 and IF-2 were introduced intraperitoneally in a single injection in doses of 100 micrograms and 1000 micrograms per mouse 2 and 7 days prior to the inoculation of P. aeruginosa strain 8 in doses of 1 and 10 LD50. The presence of substances capable of stimulating the immunobiological reserves of the body in actively growing plants (seedlings) was shown. 相似文献

The addition of bone marrow cells to spleen cells and lymph node cells stimulates by mitogents, but not to fibroblast-like cells, leads to a significant reduction of DNA synthesis in mixed cultures in vitro. The suppression effects appears only in two days and the suppressor cell activity is the stronger, the intensive is the target cell proliferation. It is shown that intact bone marrow cells can suppress the lipopolysaccharide-activated bone marrow cell proliferation in vitro. A conclusion may be draw that cells of the lymphoid system serve as target cells for the bone marrow suppressor cells, and the role of these lymphoid system cells is to control immunogenesis processes by suppressing the target cell proliferation activity in the bone marrow. 相似文献

The data presented in this paper shows the role of HLA genes and their products HLA-antigens in reproduction. The study is concentrated on new ideas of the role and mechanisms underlyin the functions of both classical and newly determined HLA genes and their products: New data and hypotheses on HLA-molecules' role in "physiological" pregnancy are discussed. 相似文献

Materials on the characterization of the vaccine Grippol, indications for its use and the results of mass use are presented. Analysis of the morbidity level in influenza and acute respiratory viral infections (ARVI) among the vaccinated persons are indicative of considerably decreased level. The coefficient of the epidemiological effectiveness of Grippol in the immunization of children has proved to be 75-95%. The conclusion has been made that the vaccine Grippol is sufficiently effective and safe for use by Russian public health service. 相似文献

Processes of interaction of immunocytes of different origin and with different cytokins, underlie the immune system mechanisms. The immune system structure, lymphocytes variety and properties, molecular basis of antigen recognition, were described. Dynamic structure of peripheral part of the immune system, immunocytes migration and re-circulation role in integration of lymphoid organs, were demonstrated. The molecular and cellular basis of the immune reaction and immune memory, were discussed. 相似文献
