Carbon monoxide comes up from the combustion of gas, wood and coal during the industrial processes and since it’s a tasteless, odorless, colorless gas it can be absorbed into body in a short time resulting acute intoxication.The result of planned inspection with laboratory analysis at Ore industrial workshops and fields located in Darkhan-Uul province conducted by Specialized Inspection Place in 2013 was higher than the permissible level which is indicated in Mongolian national standard of occupational hygiene MNS4990-2000 by 60.2 mg/m3 and was higher than the short time permissible exposing level which is indicated Occupational Safety and Health Agency (OSHA) of USA by 20 ppm, therefore we predicted that there is a pollution of carbon monoxide in present industry and conducted this study.For the determination of carbon monoxide exposure by workshops and departments, the average level of CO for workers was 17 mg/m3, maximum was 57.3 mg/m3, the average level was for dayworkers 44.9 mg/m3, for night workers it was 102mg/m3 and maximum was 427 mg/m3 in RIW. Identifying level of exposure by the type of workers, for servicemen were 96.2-427 mg/m3 for welders was 46.4 mg/m3 and mechanics was 140.5mg/m3 which were higher than others.Comparing the results of present study with the permissible level of Mongolian national standard of occupational hygiene MNS4990-2000, was higher by 50-120mg/m3 and with the 8 hours of time weighted average (TWA) of Occupational Safety and Hygiene Agency (OSHA), was higher by 20-80 ppm.

ХУРААНГУЙ. Дутуу төрөлт нь анагаах ухаан төдийгүй нийгэм эдийн засгийн тулгамдсан асуудал юм. Дутуу болон жин багатай төрөх нь нярайн эндэгдэлийн тэргүүлэх шалтгааны нэг болж байна. Шүдний тулгуур эдийн үрэвсэлт өвчний үед зарим нянгийн бүрэлдэхүүн хэсгүүд нь жирэмсэлтийн явц ба ургийн хөгжилд нөлөөлж болдог гэдгийг харуулсан судалгааны үр дүнгүүд байдаг. Иймээс жирэмсэн эмэгтэйчүүдийн тулгуур эдийн өвчин нь нярайн дутуу болон жин багатай төрөх эрсдэлт хүчин зүйл болж байгаа эсэхийг судлахад энэхүү судалгааны зорилго оршино. Уг судалгааг эмнэлэгт суурилсан тохиолдол хяналтын загвараар Нийслэлийн Өргөө Амаржих Газар болон Эх Хүүхдийн Эрүүл Мэндийн Үндэсний Төв (ЭХЭМҮТ)-ийн нийт 90 оролцогчийг хамруулан хийж гүйцэтгэлээ. Тохиолдлын бүлэг 30 (37 долоо хоногоос бага тээлттэй, 2500 гр-aaс бага жинтэй нярай) оролцогч, хяналтын бүлэгт 60 (хэвийн тээлттэй) оролцогч хамрагдсан. Судалгаанд оролцогчдийн шүд цоорох өвчний (ШЦӨ) тархалт хяналтын бүлэгт 99%, эрчим 8.32 ЦЛА/ш, тохиолдолын бүлэгт ШЦӨ тархалт 100%, эрчим 11.33 ЦЛА/ш байв. Амны хөндийн эрүүл ахуйн (АХЭА) үзүүлэлтийг үнэлэхэд хяналтын бүлэгт 2.4 буюу ‘’дунд’’, тохиолдолын бүлэгт 3.2 буюу ‘’муу’’ үнэлгээтэй байлаа. Тулгуур эдийн өвчин, шүдний чулуу (***p<0.008), шүд буйлны эмгэг хөндийн гүн 4-6 мм байх нь (***p<0.006) жин багатай дутуу нярай (ЖБДН) төрөх эрсдэлт хүчин зүйл болж байгаа нь статистик ач холбогдол бүхий үр дүнг үзүүллээ. Буйлны үрэвсэл нь ЖБДН төрөх эрсдэлийг 5.5 дахин нэмэгдүүлж байна. Community Periodontal Index of Treatment Needs (CPITN) үзүүлэлт нь АХЭА үзүүлэлтээс хамааралтай болох нь статистикийн хувьд ач холбогдолтой байлаа (***р<0.000). Тулгуур эдийн өвчин шүдний чулуу, шүд буйлны эмгэг хөндийтэй байх нь ЖБДН төрөх эрсдэлт хүчин зүйл болж байгаа нь судалгааны үр дүнгээс ажиглагдлаа.

Preterm birth is not only health problem but also one of major socioeconomic issues. Preterm Low Birth Weight (PLBW) is leading causative factor of neonatal mortality. Some researches results showed that during periodontal inflammatory disorder some bacterial components could affect pregnancy and fetal development. Therefore aim of our study is to assess and confirm periodontal disease of pregnant females whether or not risk factor of PLBW. We performed our study on the First Maternity Hospital and National Centre for Maternal and Child Health of Mongolia by clinical based case control method on 90 participants. Case group has 30 females (<37 weeks of gestation, and Neonates Birth Weight <2500), control group has 60 females (Normal birth) (ratio was 1:2). Dental caries prevalence on control group was 99%, the mean of DFM/t was 8.32 “average”, prevalence of case group was 100%, and mean of DFM/t was 11.33, which was also “average”. Oral hygiene examination assessment was poor. Study results showed that patients with periodontal disease such as dental calculus (***p<0.008) and periodontal pocket with depth of 4-6mm (***p<0.006) were risk factors for PLBW. Gingivitis is increased to have PLBW baby by 5.5 times. CPITN index was highly associated with dental hygiene index and it was statistically significant. (***p<0.000). Within the limits of this study poor periodontal health status of mothers may be a potential risk factor for a preterm low birth weight.

In this study we aimed to check a hypothesis about water sound (WS) effect can stimulate parasympathetic nervous system. A case-control study design was used. The students in control group did not listen WS, whereas students in case groups had been influenced under WSE by 3 different ways, including audio, video and shower. Data base had been obtained by performance of stress test, measurements of systolic and diastolic pressure, and counts of pulse. For statistical analysis, IBM SPSS 20.0 and Graphpad prism 7.0 were used. Interestingly, 92% of total students had stress. There were no differences between groups before WS effect. After WS effect, ANOVA test detected differences in diastolic pressure (ANOVA, F=6.209, p=0.001), stress score (F=15.21, p<0.001). Paired test was utilized to compare mean of values between before and post WS measurements, finding SP (p=0.001), SS (p<0.001) categories. It showed an effective WS influence. Chi-square test indicated that stress level of all students decreased significantly (p<0.001). But there were no differences between 3 methods of water therapy. In conclusion, WS has an effect of stimulation in immune system, useful for some diseases, in which parasympathetic system decrease and sympathetic system increases.

Background: Autism spectrum disorder (ASD) is characterized by impairments in social interaction and communication, restricted patterns of behavior, and unusual sensory sensitivities. Symptoms of autism occur in some infants, while some children are diagnosed in 2-3 years. There was a direct and indirect relationship between the dental caries and the physical growth among children. The study purpose was to determine the oral health and the body growth status among children with Autism spectrum disorder. Methods: The study population consisted of 53 children, who were diagnosed as “ASD” and approved by psychiatrist between the age of 3-18. The dental examination was done under recommendation by WHO (2013) and oral hygiene index was calculated by FedorovVolodkina (1973). Body growth status was evaluated by Kaup and Rohrer’s index. The results of the study were processed using statistical Stata-21 software. Results: The prevalence of dental caries among all children with Autism spectrum disorder was 88.6% and mean DMFT score were 2.6±3.0 in the primary dentition, 6.1±3.8 in the mixed and 4.0±2.3 in the permanent dentition. Children with good oral hygiene index were 32% of all study population and poor were 68%. When we assessed the body growth status, normal weight children were 52.8%, overweight children were 18.9% and lower weight was 28.3% of all study poptulation. Conclusion We have found that the oral health and the body growth status among children with ASD were poor.
