SUBSTANCE: invention refers to medicine, namely to gynaecology, and concerns a method for the prediction of endometrial hyperplasia in the patients with hysteromyoma following uterine artery embolisation (UAE). Substance of the method: all the patients undergo a pre-UEA diagnostic and therapeutic uterine scrapping; 6 months after the UAE, an endometrial pipelle biopsy followed by a pathomorphological study of the biopsy material is conducted. If the study shows no pathology, the biopsy materials are analysed by means of an immune histochemical study using anti-Ki-67 monoclononal antibodies; a percentage of Ki-67 proliferation marker in the uterine gland epithelium (coefficient A) and in the endometrial stroma (coefficient B) is determined; a prognostic index D1 is calculated in initial(pre-UEA) non-atypical hyperplasia, and a prognostic index D2 - in initial (pre-UEA) endometrium in the late proliferation phase: D1=A*0.05-0.74 and D2=B*0.02-0.3. If D1 is 0 or more, recurrent endometrial hyperplasia is predicted, whereas D1 less than 0 enables stating a low risk of recurrent endometrial hyperplasia. If D2 is more than 0, a low risk of developing endometrial hyperplasia is stated, whereas D2 of 0 or less shows developing endometrial hyperplasia.

EFFECT: presented method enables the high-accuracy prediction of the post-UEA endometrial hyperplasia that makes it possible to prescribe the preventive hormone therapy in due time.

SUBSTANCE: claimed invention relates to medicine, namely to immunology, and can be applied for detection of contaminants in glucose polymers. For this purpose analysis of inflammatory response is carried out in vitro with application of cell line, which represents cell line of either macrophages or differentiable in macrophages, or cell, expressing one or several toll-like receptors (TLR) or NOD-like receptors, selected from TLR2, TLR4 and NOD2. Analysis contains the following stages: (a) placing macrophages in presence of preparation of glucose polymers, which can contain anti-inflammatory contaminants, and measuring cytokine RANTES production, with production of RANTES cytokine indicating to the fact that preparation contains contaminants capable of initiating inflammatory reaction, and (b) placing cell line, which makes it possible to detect activity of innate immunity receptor or several receptors of innate immunity, selected from TLR2 and NOD2, in presence of preparation and detection of signal of reporter gene, bound to said receptor, with detection of said activity or said signal indicates presence in preparation of contaminant, which represents receptor agonist.

EFFECT: application of claimed method makes it possible to detect contaminants of glucose polymers, and addition of components, such as MDP or LPS, in tested sample makes it possible to act synergistically with contaminants, which increases sensitivity and reduces threshold of detection, with synergetic response being registered for RANTES.

SUBSTANCE: peripheral leukocyte blood values before and after a loading test are measured with the use of the gradual submaximal exercise. The method involves the differentiated recovery of different types of leukocytes from the blood to produce a preparation; a total T-cell (Tt) and active T-cell (Ta) count is determined; a Tt/Ta ratio is derived; mononuclear cells are incubated with granulocytes; a granulocyte-binding lymphocyte index (GLI) is determined in accordance with a granulocyte rosette formation (GRL - contact bound to three granulocytes) to granulocyte contact lymphocytes (GCL - contact bound to one granulocyte) ratio in the preparation; leukocyte indices: lymphocyte index (LI), immune reactivity index (IRI), adaptation index, ("CПHP") are determined; immune functional state adaptation coefficients (K) are derived for each value. Total immune functional body state TIFBS is calculated by formula TIFBS = K"спнр"+Kli+Kiri+Kgli+K"итл" before the exercise - TIFBS1 and after the exercise - TIFBS2. A specific immune functional state coefficient SIFSC is calculated by formula SIFSC = (TIFBS1+TIFBS2)/5, and a level of the immune functional SIFSC reserve is determined. If the SIFSC values are above +1.0, the level of the immune functional reserve is considered to be optimal; the SIFSC values falling within the range of 0 to 1.0 show the satisfactory reserve, whereas the SIFSC values below 0 shows the unsatisfactory reserve.

EFFECT: method enables assessing the functional body reserves with the use of combined characteristics including the adaptation body potential, immune reactivity and immune cell interaction.

SUBSTANCE: chronic infectious-inflammatory diseases (CIIDs) are diagnosed. Clinical blood analysis and bacteriological tests are conducted. A sensibilisation index (SI) and an immune responsiveness index (IRI) are calculated; total microbial count per 1 m3 of the working space air is measured, and the total microbial number (TMN) is derived. If the TMN is less than 500 CFU/m3 with no CIIDs diagnosed accompanied by the SI of less than 1.08 standard units and the IRI of less than 13 standard units, the immunoassay is considered to be inadvisable. If the TMN falls within the range of 500-2,500 CFU/m3 with one CIID diagnosed accompanied by the SI from 1.08 to 1.3 standard units and the IRI from 13.1 to 15.7 standard units, the immunoassay with the first-level tests seems advisable. Whereas the TMN exceeding 2,500 CFU/m3 with at least two CIIDs accompanied by the SI of 1.4-1.5 standard units and the IRI of 15.8-18.3 standard units, the immunoassay with the second-level tests is thought expedient.

EFFECT: invention enables detecting the workers in need of further examination for the purpose of timely immune correction in the setting of mass routine examinations.

SUBSTANCE: method is based on contacting a membrane test strip with an analysed fluid sample and initiating thereby a motion along the test strip membranes of reagents being parts of the sample or coating the membrane, and forming the immune complexes to be detected in the course of reactions in the membrane pores or on the surface thereof. A distinguishing feature of the presented method for antigen detection is that the test strip is coated additionally within the test sample contact area with a certain amount of specific antibodies, which react to the detected antigen expected to be found in the sample, when a fluid front moves and block a certain number of binding sites. The number of the coating free antibodies is specified so that the low content thereof in the analysed sample being of no diagnostic importance ensures blocking the binding sites completely that prevents the antigen from binding in the analysed area of the test strip and from developing a destructive staining in the analysed area.

EFFECT: presented approach enables reliable diagnosing based on the detection results of the antigens of gastrointestinal disorders, avoiding the achievement of positive test results for the low-antigen samples, which testifies to no development of the disease in an individual.
