Background: In recent years, kidney complication of diabetes became the basic cause of the end stage of renal disease in many countries around the world and then primary kidney disease goes on the 2-3 places. Due to the fact that diabetes mellitus turns more and more into non-communicable worldwide epidemic, we faced the increase in kidney complication which is one of form of micro vascular complications. So, illness of every 1-2 in three patients to undergo a renal replacement therapy has been diagnosed as diabetic nephropathy and of course nephrologists could not leave this fact without their attention. Goal: To study a change in the kidney structure with type 2 diabetic patients. Materials and Methods: Within the scope of the research 35 autopsied passed way because of the type 2 diabetes in clinical hospitals. According to Tervaert classification of diabetic kidney pathology issued by American Society of Nephrology in 2006, changes in glomerular structure were divided into 4 classes. Ordinary staining methods as hemotoxilin eosin, Van Gizonestaning connective tissue, Periodic Acid- Schiff standing have been used.Results: 35 autopsied in total, including 23 male (65.7%) and 12 female (34.3%) were covered by this research. And glomerular basement membrane thickening discovered in 51.4%, mesangial matrix expansion in 34.2%, Kimmelstiel-Wilson nodule in 20% and advanced glomerulosclerosis in 8.5% of total cases, respectively.Conclusions:1. It is found that diabetic kidney can be classified by Tervaert classification using ordinary standing and PAS reaction on the light microscope.2. However, we faced an essential necessity to be armed with immunofluorescence and electron microscope for the purpose to improve diagnostic examination and establish classes more accurately.3. Today when the medical science develops as evidence-based medicine, a starting the kidney biopsy samples assaying become the vital issue in comparative studying the clinical stage of diabetic kidney pathology.

Background: High blood pressure is both a cause and a complication of chronic kidney disease. As complication, high blood pressure may develop early during course of chronic kidney disease and is associated with adverse outcomes, in particular faster loss of kidney function and development of cardiovascular disease. The purpose of this study is early detection of chronic kidney disease in patients with hypertension by defining the prevalence of microalbuminuria.Methods: The study population consisted of 169 subjects with a hypertension. Individuals were considered to have hypertension if the blood pressure measured greater than 140/90 mmHg or if they were taking blood pressure lowering medications. Microalbuminuria was defined as 20 mg/l or greater. Results: We are presenting data on 169 subjects :male 38 (22.5%) female 131 (77.5%), average age 51.6±0.89 At screening, 14.8% of all participants were smokers, 62.1 % engaged in low levels of physical activity, 72.8% - were having tea with salt (table1). Microalbuminuria and renal failure, as GFR<60 ml/ min/1.73 m2, were documented in 34.3% and 16.6% of subjects, respectively. There is positive correlation between MAU and increasing-range of blood pressure (table2). Correlation was found between albuminuria and GFR(r= -0.2 p<0.01) and serum creatinine(r=0.31 p<0.01) the regression result has shown that GFR is associated with MAU and serum creatinine (table 3).Conclusions:1. In 34.3% of patient with hypertension was found nephropathies with MAU2. Microalbuminuria is increased with decline of GFR and raise of systolic blood pressure. GFR decline is with the raise of age and serum. It is important to implement in clinical practice screening of MAU hypertensive patients.3. In 2/3 of all screened subjects was found 1 and more risk factors for CVD.

BackgroundThere are 137 soums of 17 provinces have plague foci in Mongolia. The 51.7% of them is case, 23.4%- low, 9.5% - high, 0.7% - hyper active. Main host of plague foci is marmot in Mongolia. According last20 year’s surveillance study, about 75.5% of Y.pestis was isolated from marmot, marmot carcassesand their flea. Human plague cases has been caused illegal hunting marmot in Mongolia. Even legaldocument which prohibited marmot hunting was appeared since 2005, people has been hunting marmotfor selling marmot meat, skin and other products. It is depends economy crises and other public issues inMongolia. Also influenced increase risk of human plague and being reverse result in plague preventionactivities.Materials and MethodsStudy was used data of rodent for zoonotic diseases suspicious which tested plague in National centerfor zoonotic disease (NCZD) in 2005-2015 and 13 local center for zoonotic diseases in 1988-2015. Datawas kept in NCZD and National archival authority. For mapping we used Arc View 3.2.ResultsTotally 397 event information of suspicious rodents and other animals was received in NCZD from 8 districtsof Ulaanbaatar city in 2002-2015. Most of information was received from Songinokhairkhan-64.2%district and smallest number was from Nalaikh district-0.3%. 92.2% of them were marmot, 0.1% of themwere marmot raw products for treatment purpose. Totally 1285 animal samples were tested by plaguedisease and the result was negative. Five hundred thirty tree marmots were carried to Ulaanbaatar from10 provinces. In that time plague foci were active and Y.pestis was isolated in provinces which marmotwas carried to Ulaanbaatar.In 1988-2015, totally 257 marmots and animals of 515 event information was received in15 provinces.Including 13.2% of them were birds, 84% of them marmot, 1.6% of them were livestock, 1.2% of themother animals. About 216 marmots were tested by plague. 51.2% of them were detected positive results.We develop conclusion based laboratory investigation result even it need high cost to take earlyprevention and response measures.Conclusion1. It is high risk to spread plague by carrying suspicious animal in urban area. Therefore, it is importantto take early response measures even it high cost. In further, increase cost and support rapid test ofhigh technology.2. To organize rational advertisement and increase knowledge of population about not doing illegalhunting, not selling marmot raw products in urban area, not using marmot raw products for treatmentuse and avoid contact with marmot carcasses.3. It is important to cooperate joint response measures with policeman, inspection agency andveterinary and human health sectors in Mongolia.

BackgroundIgA nephropathy and MPGN are common glomerulonephritis in the world that progresses slowly andrenal function can even remain unchanged for decades. Clinically, it presents by isolated hematuria,proteinuria. Histologically, IgA nephropathy presents with acute glomerular damage, mesangial cellproliferation, endocapillary leucocyte infiltration, and crescent formations, these lesions can undergoresolution with sclerotic healing. Since 2013, renal biopsy has been done at the First Central Hospitalof Mongolia a few times. However, the confirmative diagnosis of IgA nephropathy and MPGN remainunknown in Mongolia by renal biopsy. Therefore, we intended to test renal biopsy techniques andconfirm its diagnosis by renal biopsy at the Second Central Hospital of Mongolia.MethodsUltrasound guided renal biopsy had been done for four patients by nephrologist at the Departmentof Nephrology of the Second Central Hospital of Mongolia. All four specimens were evaluated assatisfactory which show more than 8 glomerulus under the light microscopy. Each renal cortical tissuewas divided into two tips: one piece for routine H&E stain and special stains, including Masson’strichrome, and PAS stain; another piece for immunofluorescence by frozen section, which werestained with IgG, IgM, IgA and complement component 3 (C3). Each case was screened by threepathologists.Results:The case which shows mesengial widening, mesengial hypercellularity under the light microscopyor mesangial granular deposition of IgA and C3 by immunofluorescence was diagnosed as IgAnephropathy. We obtained crescent formation with glomerular adhesion in most cases. In addition, weobserved secondary MPGN in one case, which is caused by hepatitis C virus infection.Conclusion: Probably, it is a new step for developing pathologic diagnosis for nephrology in Mongolia.We needs further study for improving renal biopsy technique and confirming the diagnosis of IgAnephropathy and MPGN using electron microscopy and pathological report by oxford classification forIgA nephropathy.

Introduction: According to the World Health Organization (WHO) in 2020, brain and central nervous system (CNS) cancers account for 2% of all newly diagnosed cancers in the world and 1.5% in Mongolia. Approximately 85-90% of all brain and other CNS tumors were diagnosed primary brain tumor. In 2019, the average 5 year survival probability was 50% for other cancers and 11% for the primary brain tumors. There were 28 patients with primary brain tumor and 33 relatively healthy individuals in our study. Goal: To study the diagnostic value of serum aquaporin-4 and glial fibrous acidic protein in the diagnosis of primary brain cancer Material and Methods: The Department of Neurosurgery at Third central hospital included 28 patients with primary brain cancer and 33 relatively healthy people. The study was conducted under the permission of the Medical Ethics Review Committee of the Ministry of Health on June 19, 2019 №119. Serum aquaporin-4 and glial fibrous acidic protein content was determined by the ELISA kits method using the human aquaporin-4 and glial fibrous acid protein test kit of the Chinese company “Sanlong”. The level is assumed to be true if the p value is less than 0.05. Results Mean age of the all participants was 42.9±16.5, 64% female and 36% male. Serum aquaporin-4 protein levels were 175.71±13.3 pg/ml and serum glial fibrilliary acidic protein levels were 2.682±0.218 ng/ml in patient with primary brain tumor. Serum aquaporin-4 protein and glial fibrilliary acidic protein levels were statistically significant high (p<0.001) in patient with primary brain tumor. Serum aquaporin-4 protein and glial fibrilliary acidic protein level differences were statistically significant (p<0.05) in benign and malignant tumor. There was no statistically significant correlation between serum aquaporin-4 and glial fibrillary acidic protein level and primary brain tumor grade.

Objectives: To measure personal exposure to air pollution in children, in Ulaanbaatar, Mongolia. Methods: Since coal burning for domestic heating causes severe air pollution in Ulaanbaatar, we measured personal PM2.5 exposure for children aged 5-12 years during the winter 2013-2014. Results: Peak levels of black carbon PM2.5 exposure >200 µg/m3 between November and March varied significantly with time of day, with the highest peak 18:00-02:00, a nadir 02:00-07:00, followed by a second peak 07:00 -12:00, with another afternoon nadir 12:00-18:00. Children living in Ger districts in a Ger or wooden house, had the highest levels of PM2.5, >500 µg/m3 , with duration of personal peak exposure in Gers 8-fold longer than in wooden houses. Conclusion: Peak exposures in Gers were related to going outside, fire lighting and cooking, whereas in wooden houses peak exposures were related to going outside or opening the door. The least exposure for children was in an apartment or school with the windows shut. Significant levels of personal exposure also occurred during the commute to school, outside playtime, shopping trips and car rides. Opening the window of steam heated apartments for “fresh air cooling” as well as indoor smoking also produced important levels of personal exposure.

BACKGROUND: Toll like receptors (TLRs) are a class of proteins that key role in the innate immune system. TLR7 is expressed on monocytes, macrophages and dendritic cells, T cell, B cell and eosinophiles. TLR7, originally identified as recognizing imidaquinoline, loxibrine, broprimine and ssRNA, ssRNA viruses such as vesicular stomatitis virus, influenza A virus and human immunodefiency virus. It is known that virus ssRNA affects signaling molecule of IFN-y. Objective: To determine gene and protein activation of IFN-y signal transduction by TLR7 ligand in the endothelial cells. MATERIAL: In study we used mouse aortic linear endothelial cell which is cultured (END-D) in 5% heat- inactivated fetal calf serum (FCS), medium (DMEM) containing antibiotic mix(penicillin G, streptomycin, amphotericin B) at 37°C (5% CO2). Endothelial cells treated with synthetic IFN-γ and imiquimodligands, then the NO (nitric oxide) concentration in the supernatant is determined by Griess reagent. Endothelial cells are cultured in 6 well cell culture plate and in each well 2*104cells are expected to be grown for 24 hours of culture. Then, the cells are treated with synthetic IFN-γ and имиквимод ligand for 6 hours and the NO signaling gene activation iNOS mRNA expression which is induced by IFN-γ is determined by RT-qPCR. Endothelial cells are cultured in 12 well cell culture plate and in each well 2*104 cells are expected to be grown for 18 hours of culture. Then, the cells are treated with synthetic IFN-γ and imiquimodligands for 24 hours and the NO signaling protein iNOS expression which is induced by IFN-γ is determined by western blotting. The experiment was conducted as representation mean of at least three test results. The difference between statistical probabilities is determined by the “Students” t test. The p<0.01 value is assumed to be statistically different. RESULTS: TLR7 ligand imiquimodaugmented interferon gamma induced nitric oxide production TLR7 ligand imiquimodincreased interferon gamma induced iNOS mRNA gene expression. TLR7 ilgand imiquimodup-regulated interferon gamma induced iNOS protein expression. CONCLUSIONS: TLR7 ligand imiquimod augments IFN-γ signaling in the endothelial cells. This synergistic effect has revealed in the levels of gene and protein expression.
