INTRODUCTION:Waterborne diseases, especially diarrhea, related to water quality and safety, personal sanitation and hygienehave been still reported very high in developing countries. Globally, there are an estimated 1.4 million casesof hepatitis A every year. The hepatitis A virus is transmitted through ingestion of contaminated food and wateror through direct contact with an infectious person. Hepatitis A is associated with a lack of safe water and poorsanitation [2].Dysentery is bloody diarrhea, i.e. any diarrheal episode in which the loose or watery stools contain visiblered blood. Dysentery is most often caused byShigella species (bacillary dysentery) or Entamoeba histolytica(amoebic dysentery) [3].Kharaa and Orkhon River are tributaries of the Selenge River-basin, in which many mining and other industries,agriculture, and residential areas reside. It has become a one pollutant factor for water of the Kharaa andOrkhon rivers. As a result, water of the Tuul, Kharaa and Orkhon River was reported to be highly contaminated(Mongolian Human Development Report 2010: Water and Development report) [4].GOAL:The aim of the research was to study incidence of gastrointestinal infectious diseases among population ofsoums are located in Selenge River Basin.MATERIALS AND METHODS:Data on health statistics 2009-2013 years of gastrointestinal infectious diseases, including dysentery, diarrhea,hepatitis A virus and others, were collected and analyzed.RESULTS:Incidence of dysentery was registered highly among people who live in Mandal soums in 2009-2013 years. Butincidence of dysentery (per 10 000 population 2.82) among population ofMandal soum lower than the Selengeprovince and National average. Incidence of hepatitis A virus was registered highly among people who livein Orkhon (74.46), Orkhontuul (48.86) soums and it was greater than 1.3-2 times than the Selenge provinceaverage. Incidence of diarrhea was registered highly among people who live in Khushaat soum and it wasgreater than 2.18-3.8 times the than Selenge province averageCONCLUSION:Incidences of diarrhea and hepatitis A virus were registered highly in Orkhon, Orkhotuul and Khushaat soumscompared to other target soums and it was greater than 1.3-3.8 times than the Selenge province average.Especially, these diseases were registered highly among 0-16 aged children.

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.

In recent years, many researches that is related to waterborne diseases, especially diarrhea and water quality, safety, personal sanitation, hygiene have been conducting in developing country. Kharaa and Orkhon river are tributaries of the Selenge river basin and the many industries,agriculture, mining, provinces, soums are located in the near of Selenge river basin. Also Tuul,Kharaa and Orkhon river water is very polluted (Mongolian human Development Report 2010: Water and Development report).The aim of the research is to study correlation between to Kharaa and Orkhon river’s water pollution level and rate of gastrointestinal infectious diseases of people who live in the near of Selenge river basin.We analysed Kharaa and Orkhon river’s water quality and statistical data of gastrointestinal infectious diseases (such as dysentery, diarrhea, hepatitis A virus and others). Then we conducted correlation analysis between to river water pollution level and rate of intestinal infectious diseases. Kharaa and Orkhon river’s water was determined “less polluted” by physical, chemical andorganic indicators. But total number of bacteria was determined highly and Proteus vulgaris,Citrobacter freundi, Enterobacter agglomerans pathogens were detected in these river’s water. There were significant positive correlations between level of nitrit in river water and incidence of dysentery and diarrhea. (r=0.38, p=0.022; r=0.291, p=0.005).

Introduction. Stigma and discrimination against patients with mental illness is very common amongst the society. Therefore, this study aims to study the knowledge and understanding of mental illness and attitudes to patient with mental illness, among the general population.Goal. To assess the knowledge and understanding of mental illness and attitude to patient with mental illness among population of Ulaanbaatar city and compare its results with a similar research in carried out in 2002.Methods. The study was conducted in Ulaanbaatar city from February to April, 2008 and included 991 people aged over 18 years. The sample was selected from 30 micro districts of Ulaanbaatar city, The method of sampling was using primary dot in first step, sampling households in mid step and selecting people by using method of Sweden key from household in final step. The study used 30 item standardized questionnaires. Also there were 2 extra cards to read for respondents.Result. Among the respondents, 45% were males and 55 % females. Average age was 37 years. In view of identifying negative attitude of patient with schizophrenia, majority of respondents answered as “loony person” (n=136) and “mad person” (n=83). Conclusion. Although there was stigma amongst the study population, 66% of subjects who were involved in study could give right diagnosis in non professional level and were able to identify symptoms of mental illness suggesting that more than half of the sample studied had some knowledge of mental illness.

Introduction: Oligophrenia makes 7.3% of all mental disorders in our country. It is known that almost 4% of all diagnosed cases of oligophrenia developed as a result of an inherited disturbance of amino acid metabolism. In most countries, the frequencies of inherited diseases of amino acid metabolism in the population are determined, and preventive screening programs of newborns are implemented. No study has been conducted so far into the issue of inherited diseases of amino acid metabolism in the Mongolian population. The goal of our survey was to detect inherited disorders of amino acid metabolism in the population at risk. Materials and Methods: The collection of samples and the laboratory analysis were carried out in the following two stages:
1. The screening analysis of 514 individuals diagnosed with mental retardation was performed by paper chromatography;
2. The positivecases detected by the screening were analyzed using high-performance liquid chromatography. Results: The screening testing detected twelve potential disturbances of amino acid metabolism. Out of the twelve positive cases four individuals refused to participate in the confirmatory stage of the survey. Among the remained eight individuals, cases of hypertyrosinemia, hypervalinemia, hyperglycinemia, hyperlysinemia and pyridoxine-dependent epilepsy were detected. Conclusions
1. The fact that cases of inherited disorders of amino acid metabolism were detected among mentally retarded individuals show that the disorder is one of causes of oligophrenia.
2. A screening program of newborns should be implemented for early detection of inherited disorders of amino acid metabolism.
3. A genetic counselling and testing centre could assist in reduction of number of individuals with inherited disorders.
