Mental health team includes a psychiatrist, a psychiatric nurse, psychologist and social workers. Mental health workers are more stressful than other sector’s workers. Mental workers are working with mental patients, who have chronic,severe and poor prognosis disorders for long time, and may have Work Burnout Syndrome (WBS). Worldwide, many researches are used Maslach Burnout Inventory (MBI) for assessing WBS. Our goal was to detect risk factors of WBS among mental health workers. We conducted the survey among workers mental (doctors, nurses and assistant nurses) and study design was a descriptive cross-sectional. We are used a questionnaire, is including MBI. Our subjects were 103 workers, who were 27 (26,2%) doctors, 32 (31,1%) nursesand 44 (42,75) nurse- assistant. They were 15 (14,6%) male and 88 (85,4%) female and average age was 38.21 (SD = 8.92). The worker’s average professional working year was 13.09 (SD = 9.76). Most of subjects (n=63 61.2%) were shift-workers and they (n=99 96.1%) have high workload. We determined 3 groups by level of MBS among mental workers, such as the group with EE’s high scale (n = 27; 27%), thegroup with DP’s high scale (n = 23; 22.8%) and the group with PA’s high scale (n = 50; 50.5%).MBS was high among NMHC’s workers. However their work time is low, but theyhave risk factors for MBI such as high workloads, shift work, number of patients. Workers of emergency department had termination burnout syndrome more than other acute departments. This was associated with working condition.

INTRODUCTION:According to the report from 2010, Mongolian water consumption was 550 million cubic meter andapproximately 9.1% of the total Mongolian population obtain their water from inadequate hygiene waterresources - springs and rivers. Due to non-hygiene water usage has caused water-born communicableand non communicable diseases among the population. In the last years there has been issue of pollutionof one of the Mongolia’s more representative river Selenge and its following rivers -Kharaa, Orkhon andit is necessary to evaluate water pollution of these rivers.GOAL:To determine water chemical and biological pollution of Kharaa and Orkhon river and to evaluate waterqualityMaterials and MethodsWe collected water, sediments and macro invertebrates sample from three points of river -upstream,midstream, downstream and for Kharaa river the samples were collected from Tunkhel, Mandal andBayangol soum, fo Orkhon river the sequence was Orkhontuul, Orkhon, Khushaat soum. Samples werecollected June, August, October of 2011, 2013.In water sample, we determined physic-chemical 15 parameters including temperature, pH, total dissolvedsolids, conductivity, smell, color, hardness, sulfate, chloride, nitrate, nitrite, ammonia, dissolved oxygen,biological oxygen demand and mercury using their standard methods. Macro invertebrate samples werecollected to evaluate water quality and we determined mercury in sediments and macroinvertebratesamples to evaluate mercury contamination.RESULT:Physic-chemical results of the water showed that water of Kharaa, Orkhon rivers were classified lowmineralized, soft water and nutrient pollution indicators for ‘slightly polluted’category. For dissolved andbiochemical oxygen, they were belong to the category of ‘pure water’.There were no correlation between 2012 and 2013 results and mercury in water, sediments and macroinvertebrates were qualified standard value.CONCLUSION:According to research results water quality of Kharaa, Orkhon river was good and have less pollution andit is possible to use in household consumption after proper cleaning and disinfection.

Background. The abuse experiences can change the normal development of the child with the consequences being visible after many years even throughout the whole life. The relation between childhood abuse and the psychiatric disorder in adulthood is reported in a great number of epidemiological studies and researches based on the clinical population surveillance. Numerous studies have significantly expressed the relation between childhood abuse and anxiety, the development of anxiety disorders. Limited research has shown a possible association between exposures to child abuse the risk of developing physical parameter changes as an adult.Goal. To study anxiety and some physical parameters among abused adolescentsMaterials and Method. There were selected46 abused children and 48 non abused children aged between 11-16 years old. The Spence Children’s Anxiety Scale (SCAS; Spence, 1997) is a38-item selfreport questionnaire that assesses multiple symptoms of childhood anxiety disorders based on current diagnosticcriteria. The height, weight, heart rate, breath rate and blood pressure of all participants in the study were measured according to standardized methodology.Results. Average age of all subjects in the study was13.51±1.61 and 60% of them were female and 41% male. All anxiety symptoms of case group was statistically significance higher (p<0.01) than the control group. Significantly more abused children (147.09±10.16) showed stunting compared to 4 sm of non-abused (151.53±10.26).Conclusion. In the present study, abused children were 2.8 times as likely as children with no maltreatment. Also significant stunting was found among abused children identified does differ from the growth of children who are not abused.

IntroductionRheumatoid Arthritis (RA) is chronic systemic inflammatory autoimmune disorder that still remains a disease of unknown etiology and complex disease without a single treatment that is dominated by serious and debilitating sequalae resulting from synovial membrane, cartilage and progressive joint destruction involvement. There is a one major obstacle in elucidating the early events in the pathogenesis of RA has been the lack of definition of the initial features of the disease. To overcome these difficulties, various animal models have been developed. But Collagen Induced Arthritis (CIA) mouse model is known to be the most valuable animal model to explore the pathogenic process, molecular and cellular mechanisms of joint destruction, to discover the immune system respond and activation and to develop new effective treatment methods and useful drugs [1].Materials and Methods:Within this study we have used 40 male mice at age 6-8 weeksfor 0-60 days and divided into following 4 groups which are:I group–CIA induced mouse group treated with Derveger Jirgeruu (Saposhnicovia divaricata) (n=12) II group–CIA induced mouse group treated with Natriisalicylas (10%) (n=12) III group–Healthy control mouse group (n=8) IV group–CIA inducedcontrol mouse group (n=8). To induce CIA model, we have used standard method of Murali /2005/’s design. Standard drug Natriisalicylas (10mg/ 20gr), one of the often used drug anti-inflammatory and Mongolian herbal plant Derveger jirgeruu (Saposhnicovia divaricate) (0.26mg/20gr) were daily administered by orally, starting on day 21 until day 60.To evaluate and compare 2 drug’s anti-inflammatory effect, we have done clinical score evaluation (Kim W.U, 2002), laboratory testing and histological examination of the joints using standard methods.ResultTo summarize the research result, both medications have proven to be as a medication which has anti-inflammatory effect that decreased the signs and symptoms of RA by it is histological and laboratory analysis.Conclusions:1. CIA model was effectively induced, which have proven by clinical signs, laboratory result and histological examination.2. Within this study it has proven that traditional herbal medicine Derveger Jirgeruu (Saposhnicovia divaricate) (0.26mg/20g) have anti-inflammatory effect on CIA induced mouse model of Rheumatoid Arthritis, which have had similar effect asstandard non-steroid medicine Natriisalicylas (10mg/20g).

Since ancient times, arsenic (As) compounds have been used to cure certain ailments. However, it is a metalloid poison, with cancerous effects. The main cause of poisoning from arsenic is usage of arsenic containing drinking water. According to WHO reports the permitted maximum level of arsenic in drinking water is 0.01 ppm. According to the study conducted in 57 sums (unit of the province) of 17 provinces of Mongolia, arsenic levels in drinking water in some provinces especially Dornogobi, Dundgobi and Gobisumber located in the southern part of Mongolia were higher than the allowed level. Therefore, there is a great risk of arsenic related diseases among Mongolian population. The aim of this study is to induce arsenic related pathology in albino mice and examine the effect of vitamin C on it. Six to eight week old 20 female Beijing breed mice weighing 20-25 g were used. Experiments were carried out in vivarium (20±2℃) of “Monos” medical university. Mice were fed with normal food for 28 days. Animals were divided into 4 groups: group A or control group without arsenic treatment, group B received arsenic at 1mg/kg per day, group C received arsenic at 30 mg/kg per day, and group D received arsenic 30 mg/kg per day and vitamin C at dose of 20 mg/kg. The arsenic and vitamin C were administered orally. After the treatment blood samples were taken and analyzed for levels of АST, АLT, total protein, and glucose. Hystopathological analysis of mice heart, liver, kidneys and lungs were also performed. Weight losses in animals of all arsenic treated groups were observed. Arsenic increased levels of АLT and decreased levels of АST, glucose and total protein in a dose dependent manner. Hystopthological analysis revealed chronic inflammation, dystrophy, and necrosis in the heart, liver, kidneys, and lungs in mice administered arsenic. There were lesser change and injury detected in mice treated with vitamin C.

BACKGROUND. Sensorineural hearing impairment (SNHI) is the most common inherited sensory defect, affecting about 3 per 1000 children. More than 50% of these patients have a genetic cause (i.e. hereditary hearing impairment; HHI). Mutations in certain genes were noted to be extraordinarily popular in the deaf patients across different populations, making molecular screening feasible for these common deafness genes. One of the most important characteristics that we have learned concerning hereditary hearing loss is that common deafness genes and their mutations are usually different according to the ethnic background. As demonstrated in our previous studies performed in Taiwanese patients, the mutation spectrums of common deafness genes, such as the GJB2 gene and the SLC26A4 gene, are different from those in the Caucasian or even other Asian populations. These findings further underscore the indispensability of the collection of local data in terms of genetic counseling. In the collaborative project, we have successfully established a cohort of >100 hearing-impaired families, and clarified the genetic epidemiology of deafness in the Mongolian population. We identified several special deafness mutations such as GJB2 c.23+1G>A, c.559_604dup, and SLC26A4 c.919-2A>G, and our results revealed that Mongolian patients demonstrate a unique genetic profile in deafness as compared to other East Asian populations (paper in preparation). Meanwhile, by organizing a seminar at National Taiwan University Hospital in March 2017, we have transferred crucial concepts and techniques regarding how to perform genetic testing for deafness to the Mongolian colleagues. In the future, we plan to strengthen the mutual collaboration by expanding the clinical cohort and upgrading the genetic examination platform using the NGS techniques.

Background: According to WHO research, there are approximately 24 million people living with schizophrenia worldwide and schizophrenia is characterized by a combination of psychotic and non-psychotic symptoms. Since the cause of the disease is not fully understood, antipsychotic medications are used as symptomatic treatment. According to the 2022 statistics of the NCMH, 718 people with schizophrenia are being treated under active surveillance in Mongolia. The reason for conducting this study is that the manifestation of drug side effects resulting movement disorders in patients with schizophrenia, which has not been studied in Mongolia. Aim: To investigate the relationship between adherence of medication regimen and abnormal involuntary movements in patients with schizophrenia. Materials and Method: The study was conducted using a descriptive method, cross-sectional design, purposive sampling with the questionnaire and standardized tests. Ethical approval for this study was approved by the NCMH (№3/77 30th of January, 2023) and Research Ethics Review Committee of MNUMS (№2023/3-02). Each participant was asked to complete 5 groups of 36 questionnaires, and standard tests were used to assess patients’ adherence to medication regimens (Morisky scale) and abnormal involuntary movement scale (AIMS). The study was conducted between March and August 2023, and the results were summarized and analyzed using STATA 14 software. Results: The study included 209 patients with schizophrenia, aged 18-79 years, of whom 47.4% (n=99) were male and 52.6% (n=110) were female (p=0.21). Of the participants, 28.2% (n=59) had less than secondary education, 76.5% (n=160) were unmarried, and 85.2% (n=178) had a disability due to mental health. 32.5% (n=68) of the patients with schizophrenia in the study used a combination of typical and atypical medications, and the most commonly used antipsychotic drugs were haloperidol (30.6%), chlorpromazine (26.8%), levomepromazine (25.8%), risperidone (24.4%), and quetiapine (21.1%). 1.4% (n=3) of the patients had good, 52.6% (n=110) had moderate, and 45.9% (n=96) had poor adherence to the medication regimen (Cronbach’s α=0.781). However, according to the results of the test for assessing abnormal involuntary that are performed without self-control, 49.76% (n=104) responded that they felt more sensitive to facial and oral movements, and 44.5% (n=93) to limb movements. The patients’ adherence to the medication regimen was statistically significant with facial and oral movements (n=104; p=0.036) and general body movement disorders (n=94; p=0.05). Conclusion 32.5% of patients with schizophrenia were taking typical and atypical antipsychotics, and 45.9% had poor adherence to medication regimens and were more likely to exhibit clinical forms of abnormal involuntary movements, including facial (p=0.036) and general movement disorders (p=0.05).

Background: In the treatment of plaque-induced gingivitis, in addition to mechanical plaque control, the use of chemical plaque control such as mouth rinses for a certain period has shown a positive effect on treatment outcomes and prognosis. Aim: To evaluate the efficacy of a probiotic mouthwash in the treatment of plaque-induced gingivitis. Materials and Methods: A randomized controlled clinical trial was designed for a period of 2 weeks on 45 systemically healthy subjects between 20 and 25 years having plaque-induced gingivitis. The study population was divided into three groups. Group 1-15 subjects were advised experimental (probiotic) mouthwash. Group 2-15 subjects were advised positive control (chlorhexidine) mouthwash and Group 3-15 subjects into a negative control group. Oral prophylaxis was done for all groups at baseline. After the proper oral hygiene instructions, groups 1 and 2 were instructed to rinse their mouth with 15 ml of their respective mouthwashes, for 1 min twice daily, 30 min after brushing. Clinical parameters such as Full mouth plaque score (FMPS), Full mouth bleeding score (FMBS) were assessed at baseline, 2 weeks respectively. Results: At baseline, there was no statistically significant difference between the groups in terms of FMBS and FMPS mean values (p=0.174, p=0.887). At day 14, the FMPS, FMBS mean values were significantly reduced by all treatment modalities ranking probiotic and chlorhexidine is greater than negative control group (p<0.001, p<0.001). Conclusion The probiotic mouthwash was effectively used as an adjunct to mechanical plaque control in the treatment of plaque-induced gingivitis.

Introduction: The aim of this research project is to elucidate the crosstalk of innate and adaptive immune reactions against the DNA containing bacteria. : This study held in the Core laboratory, Science Technology Center, Mongolian National University of Medical Sciences (MNUMS). Murine aortal endothelial cells, END-D cultured and the cell viability checked by MTT assay. In addition, the NO production, protein and gene expression studied by Griess Reagent assay, R.T-PCR and immunoblotting, respectively. Results: 0.1µM, 1µM and 10µM of TLR9 ligand exhibited no cytotoxic action against the cells by MTT assay. IFN-ү alone induced NO production in END-D cells. In the other hand, TLR9 ligand at 0.1µM, 1µM and 10µM up-regulated IFN-ү induced NO production in dose dependent manner. RTPCR results exhibit that TLR9 ligand up regulates iNOS mRNA. Immunoblotting analysis showed the enhanced iNOS protein expression and phosphorylation of STAT1 in cells pre-treated with TLR9 ligand. Discussion: We have demonstrated CpG DNA, TLR9 ligand, up-regulates IFN-ү induced NO via enhanced IFN-ү signaling. The result of Western Blotting and RT-PCR support the up-regulation of NO. CpG DNA can be used as agent against virus and bacteria. Further research need to be conducted. Conclusion TLR9 ligand, CpG DNA up-regulates IFN-ү induced NO production in time and dose dependent manner. TLR9 ligand augments the expression of iNOS mRNA and STAT1 phosphorylation in response to IFN-ү.

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.
