The invention relates to medicine, namely to infectious diseases, Nephrology and dermatology.

Early etiological diagnosis of specific infectious renal pathology is important to ensure the effectiveness of its treatment.

You know the identification of sediments Chlamydia trachomatis in glomerular area and localization of antigens of this type of chlamydia in the interstitial space lifetime obtained needle biopsies in patients with IgA nephropathy. The study of Chlamydia trachomatis antigen in tissue was performed using monoclonal antibodies (rakityansky I. A., Ryabov ie, the Role of Chlamydia trachomatis renal tissue in the pathogenesis of IgA nephropathy taking into account the patient's age // Journal of Infectology. - 2012. - So 4, No. 1. - S. 29-35.

The main disadvantages are the counterpart of its invasiveness and loss of use for early, before the manifestation of clinical manifestations diagnosis of specific infectious diseases of the kidney, caused by Chlamydia trachomatis.

The closest analogue prototype is the use of PCR for detection of Chlamydia trachomatis in the upper urinary tract in patients with symptoms of acute pyelonephritis. The sample for the study was taken during surgery of the upper urinary tract by aspiration of urine from the renal pelvis or ureter above the level of obstruction [Dimitrakov J., V. Ganev, Zlatanov So, Detchev I, Horvat, A., S. Kirov, Vatchkova I., D. Dimitrakov PCR studies on the presence of Chlamydia trachomatis in the upper urinary tract of patients with obstructive pyelonephritis // Folia medica. - 1998. - Vol.40, No. 3. - P. 24-28].

The main disadvantages of the prototype are its invasiveness and loss of use for early, before the manifestation of clinical manifestations diagnosis of specific infectious diseases of the kidney, caused by Chlamydia trachomatis.

The main problem to be solved by the invention is to provide a non-invasive and informative early, before the manifestation of clinical manifestations diagnosis of specific infectious diseases of the kidney, caused by Chlamydia trachomatis, using the definition in the urine of molecular markers.

The problem is solved by the fact that you define in the urine gas chromatography and mass spectrometric methods 2-propenamide, N-amino-oxymethylene, 2-methyl-5-(1-methyl-ethyl)-phenol and 4-4-dihydroxy-diphenyl-sulfon and when the amount of 0.002-0.06 mmol/l; of 0.002-0.06 mmol/l; 0.003 to 0.11 mmol/l and of 0.002-0.05 mmol/l, respectively diagnose specific infectious pathology of the kidney, caused by Chlamydia trachomatis.

As a result of our research were first identified by gas chromatography-mass spectrometry of urine parameters, showing together about the presence of infectious and chronic kidney disease caused by Chlamydia trachomatis, not only after the beginning of the manifestation of clinical manifestations of pathologists the kidneys, but before the manifestation deployed clinical manifestations of chronic kidney disease.

Hence, the legitimate conclusion about conformity of the proposed solutions to the criterion "novelty".

The above set of essential features necessary and sufficient for obtaining a technical result - providing non-invasive and informative early, before the manifestation of clinical manifestations diagnosis of specific infectious diseases of the kidney, caused by Chlamydia trachomatis, using the definition in the urine of molecular markers.

Between the existing signs and solve problems there is a causal relationship, where each topic are needed and effect on obtaining a technical result which, together, signs sufficient to obtain it. Legitimate conclusion about conformity of the proposed technical solution the criterion of "inventive step".

SUBSTANCE: invention aims at asserting the maximum allowable blood concentrations (MAC) of heavy metals in the children living in the dirty environment as shown by health risk criteria after the chronic integrated exposure. An environmentally neglected zone is selected; a representative sampling of the children for the examination is drawn that is a basic group with using biological, social and hygienic criteria; the same criteria are used to draw a representative sampling of the children to a reference group living in the environmentally friendly zone. In the territory of the above zones, the chronic exposure of the analysed heavy metal is qualitatively assessed by establishing its average daily concentration in the ambient environment; the derived value is used to calculate a total average daily doses of a heavy metal supplied from various sources into a child's body averaged over the annual exposure for the children of both groups. Blood is sampled from the children every three months for one year to determine the content of the analysed heavy metal and also to measure the biochemical values of blood plasma and serum characterizing body responses presented by actual or potential health problems that are response markers. That is followed by calculating the average blood concentration of the analysed heavy metal and comparing it to the reference for the same heavy metal with using a Student two-sample test, thereby stating whether the children were sampled from the main and reference groups adequately. A mathematical modelling procedure is used to establish a relation between the exposure that is the total average daily doses of the analysed metal, and the exposure marker that is the average blood metal concentration. A sliding window technology is used to assert the response markers selected. The maximum allowable concentration of the exposure marker and respective marker is determined by a technique based on ratio analysis.

EFFECT: enabled measurement of the blood MAC of the heavy metals in the children after the integrated exposure with using sparing techniques making it possible to avoid a health risk.

SUBSTANCE: method involves taking blood from ulnar vein (systemic blood circulation) and from large vein of the injured extremity proximal with respect to lesion focus (regional blood circulation). Spontaneous NST-test value is determined and difference is calculated in systemic and regional blood circulation as regional-to-systemic difference. The difference value is used for predicting clinical course of pyo-inflammatory disease in extremities.

EFFECT: high accuracy of diagnosis.

SUBSTANCE: one should introduce biologically active substance, moreover, in patient's blood serum one should detect the content of acetyl choline and choline esterase activity followed by 2-h-long intragastric pH-metry at loading with biologically active substance as warm 40-45%-honey water solution at 35-40 C, and at increased content of acetyl choline being above 1.0 mM/l, choline esterase being above 0.5 mM/l/30 min and pH level being 6.0-6.9 it is possible to consider apitherapy to be useful for treating ulcerous duodenal disease.

EFFECT: higher efficiency and accuracy of detection.

SUBSTANCE: it has been suggested a new method to detect pharmacological sensitivity to preparations as acidosuppressors. After the intake of the preparation a patient should undergo fibrogastroduodenoscopy 3 h later, then, through endoscopic catheter one should introduce 0.3%-Congo red solution intragastrically and the test is considered to be positive at keeping red color that indicates good sensitivity to the given preparation, and in case of dark-blue or black color the test is considered to be negative that indicates resistance to this preparation. The suggested innovation widens the number of diagnostic techniques of mentioned indication.

EFFECT: higher efficiency of diagnostics.
