[Level of sIgA, IgG, IgA in vaginal secretion in women with chronic inflammatory disease of small pelvis organs].

AIM: Determine levels of sIgA, IgG, IgA in vaginal secretion and saliva of women of reproductive age with chronic inflammatory diseases of small pelvis organs (IDSPO) at exacerbation stage and remission period. MATERIALS AND METHODS: Clinical-laboratory and gynecological examination of 105 women was carried out. Based on the results obtained 3 groups were formed: patients with IDSPO at exacerbation stage; patients at remission stage; clinically healthy women. sIgA, IgG, IgA parameters were studied in vaginal secretion and saliva in women with IDSPO at exacerbation stage and remission period by radial immune diffusion in gel by Manchini method. RESULTS: An increase of immunoglobulin level in vaginal secretion of women with IDSPO at remission period and a sharper increase of these parameters during exacerbation of the disease compared with women of the control group were detected. During analysis of sIgA, IgG, IgA levels in saliva in the same groups of women the results were obtained that give evidence that the presence of IDSPO and local immune reaction do not lead to the changes of these parameters. CONCLUSION: The obtained parameters on the dependence of an increase of immunoglobulin levels in vaginal secretions and the degree of intensity of the inflammatory process give basis to use them with the aim of additional diagnostics.

[Expression of TLR2 and TLR9 genes by epithelial cells of cervical canal mucous membrane in women with inflammatory diseases of small pelvis organs].

AIM: Determine subpopulation composition of blood lymphocytes and the level of expression of TLR2 and TLR9 by epithelial cells of cervical canal mucous membrane in women of reproductive age with inflammatory disease of small pelvis organs (IDSPO) at exacerbation stage and remission period. MATERIALS AND METHODS: Clinical-laboratory and gynecological examination of 105 women was carried out and 3 groups were formed based on the results: patients at IDSPO exacerbation stage; patients at remission stage; clinically healthy women. By using real time PCR, TLR2, TLR9 gene expression levels were determined in epithelial cells of cervical canal mucous membrane in women of all the 3 groups. Subpopulation composition of blood lymphocytes was determined by flow cytofluorimetry by using monoclonal antibodies with CD45+ CD3+ -T-cell, CD45+ CD3+ CD4+ -T-helper, CD45+, CD3+, CD8+ -T-suppressors-cytotoxic killers, CD45+, CD3-, CD16+, CD56+ natural killers, CD45+, CD3-, CD19+ -B-lymphocytes. Immune fluorescence reaction evaluation was carried out in flow cytofluorimeter Cytomics FC 500 (Becton Coulter, USA). RESULTS: The level of expression of TLR2 gene in the studied groups of patients was established not to differ significantly from parameters in the comparison groups, however it should be noted that this parameter in women with IDSPO at exacerbation stage (causative agents of the infectious process--ureaplasma, staphylococcus, candida) was somewhat higher than in the comparison group. Significantly high level of TLR9 gene expression in cervical canal epithelial cells was detected to correlate with the presence of infectious causative agents. In the group of women with exacerbation of the infectious process the expression of TLR9 was 14.5 times higher compared with the group of women without IDSPO. Among groups of women with IDSPO significant differences in relation to control group in relative and absolute levels of CD3+ T-lymphocytes; CD4+ T-helpers; CD8+ cytotoxic killer T-suppressors, B-lymphocytes compared with the same parameters in clinically healthy women were not detected. CONCLUSION: The increase of TLR9 gene expression level in cervical canal cells of women with IDSPO may serve as an additional diagnostic feature of the presence and degree of severity of the disease.

[The use of microdot immunoenzyme analysis with visual detection for the determination of tularemia antibodies]. / Ispol'zovanie mikrotochechnogo immunofermentnogo analiza s vizual'noi indikatsiei dlia opredeleniia tuliaremiinykh antitel.

The possibility of using the micropoint enzyme immunoassay (EIA) on a nitrocellulose membrane with the visual evaluation of results for the detection of tularemia IgG antibodies in hamadryas baboons at the postvaccinal period has been studied. The sensitivity of this assay has been compared with that of the passive hemagglutination (PHA) test, the microagglutination (MA) test and EIA with the spectrophotometric evaluation of results in plates. As shown in this study, EIA in the above-mentioned modification can be successfully used for the detection of tularemia antibodies in the blood serum. The sensitivity of micropoint EIA has proved to be not inferior to that of EIA in plates, while exceeding the sensitivity of the PHA test 10- to 20-fold and the sensitivity of the MA test 10- to 1,000-fold. This method is simple, reliable, highly sensitive, economic and requires no special equipment, which makes it highly promising for the diagnosis of tularemia and the evaluation of humoral immunity at the postvaccinal period.

[The natural background of chromosome anomalies in the bone marrow cells of mice and the control of vaccines for genotoxicity]. / Estestvennyi fon khromosomnykh anomalii v kletkakh kostnogo mozga myshei i kontrol' vaktsin na genotoksichnost'.

The levels of chromosomal anomalies in marrow cells of mice kept under conventional conditions in the animal house of the Mechnikov Research Institute for Vaccines and Sera (Moscow) and under specific pathogen-free conditions were compared by the micronuclear and metaphasic methods. In the animals kept under specific pathogen-free conditions the occurrence of anomalies did not exceed the normal level; in the animals of the other group the level of cells with aberrations was 4-5 times higher. All detected aberrations in the chromosomal structure were unstable. The results obtained in this investigation indicate that under the conventional conditions existing in the animal house of a microbiological research institute mitogens of the biological nature may be present.

[Microdot immunoenzyme analysis of chorionic gonadotropin in pregnancy]. / Mikrotochechnyi immunofermentnyi analiz khorionicheskogo gonadotropina pri beremennosti.

A microdot enzyme immunoassay test system has been developed for measuring chorionic gonadotropin levels in urine samples, on the basis of affine purified antibodies to hormonal beta-subunit and antibody complex with horse radish peroxidase. The results are assessed visually with the use of a color indicator scale obtained in experiments with reference preparations containing 12.5, 50, and 200 mMU of the hormone per ml. Comparison of the intensity of microdot color permits characterizing the level of hormone secretion and diagnose pregnancy 4-5 days before the first day of expected menstruation (50 mMU/ml). The specificity, reproducibility, and sensitivity of the developed test system are not inferior to common enzyme immunoassay on the plates; the method does not involve the use of sophisticated equipment and is reagent-saving. The diagnostic accuracy of the test system is 100 percent.

[Local immunity in acute dysentery. II. The content of antibody-forming cells in the large intestine mucosa in acute Flexner dysentery in the dynamics of the disease]. / O mestnom immunitete pri ostroi dizenterii. Soobshchenie II. Soderzhanie antiteloobrazuiushchikh kletok v slizistoi tolstoi kishki u bol'nykh ostroi dizenteriei Fleksnera v dinamike zabolevaniia.

Antibody-forming cells were detected in the large intestine of patients with acute Flexner's dysentery by means of the modified Jerne - Nordin method of hemolysis in agar. This method allowed one to determine the classes of immunoglobulins produced by the cells contained in tissue microspecimens obtained by the biopsy of the intestinal mucosa. The maximum amount of antibody-containing cells could be detected on days 7-12 of the disease. The content of antibody-forming cells was shown to depend on the severity of dysentery, the duration of the disease and the therapeutic methods used in the process of treatment. IgA was found to be the most frequent antigen type.
