Background:
Adhesion small bowel obstruction (ASBO) is a common complication following abdominal surgery and can significantly impair postoperative recovery. This condition necessitates the exploration of more effective therapeutic approaches.
Aim:
The aim of this study was to evaluate the clinical efficacy of Traditional Mongolian Medicine (TMM) combined with acupuncture in the management of postoperative ileus secondary to adhesion-related small bowel obstruction.
Case Presentation:
We report the case of a 47-year-old female patient who developed postoperative ileus. The therapeutic intervention consisted of a combined regimen of traditional herbal pharmacotherapy and electroacupuncture. The clinical outcomes were assessed based on the resolution of symptoms and the restoration of gastrointestinal function.
Result:
Following the administration of the integrated treatment, the patient exhibited a marked reduction in abdominal pain. Objective clinical improvement was noted through the successful restoration of intestinal peristalsis and the normalization of flatus and defecation.
Conclusion
The findings of this case study suggest that Traditional Mongolian Medicine, particularly when integrated with electroacupuncture, may be an effective and viable modality for promoting the recovery of gastrointestinal motility in patients with adhesion-related small bowel obstruction.

Introduction:
The World Health Organization (WHO) reports that noise pollution leads to a variety of
short-term and long-term health issues, including sleep disorders, cardiovascular diseases,
impaired concentration, decreased performance at work and school, and hearing difficulties.
It has been established that for every 10 dB increase in environmental noise, the incidence
of heart attacks among individuals aged 65 and older increases by 3.9% compared to those
living in quieter environments (Seidler, et al., 2016). Furthermore, it has been found that
noise pollution exceeding 65 dB is directly related to hypertension among residents living
along high-traffic roads.
Objective:
To assessing traffic load and noise pollution on the roads of Ulaanbaatar
Materials and Methods:
The study was a cross-sectional survey conducted to determine noise pollution at 15
locations along roads such as Sun Road, Peace Avenue, Ard-Ayush Street, and Ikh Toiruu.
Measurements were taken during morning (7-9 AM), afternoon (12-2 PM), evening (5-7 PM),
and night (11 PM-1 AM) using a Noise Meter, Sound Level Meter, and portable equipment.
Measurements were conducted at one point 100-200 meters from the main road, with three
repetitions to assess hearing levels. Statistical analysis was performed using SPSS-24
software, and the results were compared to the Air Quality Technical General Requirements
MNS 4585:2016 standard (During the day (07:00-22:00), 60 dB(A), and at night (22:00
07:00), 45 dB(A)).
Results:
The measurement results revealed that the maximum noise value in the morning (7-9 AM)
was 83 dB(A), the minimum noise value was 51 dB(A), and the average of the maximum
noise values was 74.1±4.7 dB(A). The maximum noise value during the day was 97 dB(A),
the minimum noise value was 47 dB(A), and the average of the maximum noise value was
74.4±6.9 dB(A). In the evening, the maximum noise value was 88 dB(A), the minimum noise
value was 47 dB(A), and the average of the maximum noise value was 74.4±6.6 dB(A). For
the night measurements, the maximum noise value was 86 dB(A), the minimum noise value
was 49 dB(A), and the average of the maximum noise value was 69.4±7.7 dB(A).
When calculating the average noise pollution on weekdays and weekends, the average of
the max and min values during the morning, evening, and night on weekdays was 0.59-4.33
dB(A) higher than that of the weekend. The average maximum value during the day on
weekends was 2.79 dB(A) higher than that of weekdays. The number of vehicles participating
in road traffic showed a strong positive correlation with environmental noise (Rxy=0.660,
p=0.0001), and the number of times the horn was sounded also revealed strong positive
correlation with environmental noise (Rxy=0.674, p=0.029).
Conclusion
The noise level along the main roads exceeds the permissible limits set by the
"Air Quality. Technical General Requirements MNS 4585:2016" standard by 37 dB(A) during
the day and by 41 dB(A) at night. The average maximum value during the day exceeds the
standard by 14.6 dB(A). This indicates that Ulaanbaatar is experiencing noise pollution at
levels that negatively affect the health of the urban population.

Mongolian Journal of Health Sciences 2025;85(1):239-243
Background:
Rhododendron adamsii (Sagaan Dalya) is a medical plant widely distributed in the Altai region, Mongolia,
and Russia. It is traditionally used for its calming, restorative, and immune-boosting properties. Inflammation is a complex immune response against pathogens such as bacteria, viruses, and fungi, involving macrophages, fibroblasts, mast
cells, and neutrophils. These cells release inflammatory mediators such as nitric oxide (NO), TNF-α, and IL-1β.
In collaboration with the Russian Foundation for Basic Research, a project was initiated to investigate the bioactive fractions of Rh. rosea (L.) and Rh. adamsii and their effects on the production of TLR4 signaling end products
and associated protein activation. Previous studies within this project have shown that certain bioactive fractions exhibit
anti-inflammatory activity. Specifically, fraction 7.11 suppressed NO production and inflammatory signaling molecules
in LPS-stimulated RAW 264.7 macrophages, while fractions 7.46 and 7.52 influenced the phosphorylation of proteins
such as ERK1/2, JNK, and IRF3. These findings suggest the need for further investigation into the effects of Rh. adamsii
bioactive fractions on inflammatory signaling pathways.
Aim:
This study aims to evaluate the effects of bioactive fractions derived from Rhododendron adamsii on the production
of TLR4 signaling end products in RAW264.7 macrophage cell cultures.
Materials and Methods:
The study was conducted using RAW264.7 macrophage cell cultures and bioactive fractions
extracted from Rh. adamsii, dividing the experiments into three groups. After stabilization, RAW264.7 cells were stimulated with 100 ng/mL LPS. Based on previous studies, non-toxic concentrations of bioactive fractions (10 µg/mL) were
applied. NO production was measured using the Griess assay, while TNF-α and IFN-β cytokine levels were evaluated
using ELISA. Each experiment were repeated three times, and data were statistically analyzed using SPSS 25.0, applying
One-way ANOVA and Independent Samples T-test.
Results:
The NO production in the positive control group was significantly higher compared to the negative control. In
contrast, the experimental groups showed a statistically significant reduction in NO production, suggesting a potential inhibitory effect on TLR4 signaling in macrophages. However, fraction 7.48 reduced TNF-α levels while increasing IFN-β
production, but these changes were not statistically significant. Similarly, fraction 7.55 slightly reduced TNF-α and IFN-β
levels, but the effect was also statistically unsignificant.
Conclusion
The bioactive fractions 7.48 and 7.55 of Rh. Adamsii reduced nitric oxide (NO) production in LPS-stimulated macrophage cell line cultures, suggesting that they may inhibit TLR4 signaling. However, their lack of effect on
TNF-α and IFN-β production indicates that they do not influence TLR4 signaling mediated by these cytokines. Instead,
they may affect the final product output through other pathways or different stages of signal transduction.

Mongolian Journal of Health Sciences 2025;88(4):112-116
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.

Abstract
Epilepsy, a neurological disorder characterized by recurrent seizures, affects millions of people worldwide. Significant advancements in both diagnostic and therapeutic approaches have greatly improved outcomes, particularly for individuals with drug-resistant epilepsy. Modern neurostimulation techniques such as Responsive Neurostimulation (RNS), Deep Brain Stimulation (DBS), and Vagus Nerve Stimulation (VNS) have demonstrated effectiveness in reducing seizure frequency in these patients. Additionally, emerging technologies like gene therapy and optogenetics are being explored to better understand the underlying mechanisms of epilepsy and hold promise as future treatment modalities.Traditional imaging techniques often fail to detect subtle epileptogenic zones. However, the introduction of ultra high-field 7T MRI scanners represents a major breakthrough. These advanced scanners use eight transmitters to generate higher-resolution images, reducing signal dropout and enabling the identification of previously undetected lesions. In one study involving 31 patients, 58% had their treatment plans modified based on 7T MRI findings, highlighting its potential to inform surgical decision-making. In terms of pharmacological treatment, newer medications such as sultiame, cannabidiol (CBD), and non-pharmacological approaches like the ketogenic diet have emerged as additional therapeutic options for drug-resistant epilepsy. These developments contribute to more effective, personalized management strategies for epilepsy. In summary, the landscape of epilepsy diagnosis and treatment is rapidly evolving. Innovations in imaging and therapeutic interventions are offering new hope for patients with drug-resistant epilepsy. Ongoing research and clinical trials remain essential to further refine these approaches and improve patient outcomes.

Mongolian Medical Sciences 2025;212(2):42-51
Introduction:
According to the WHO, being exposed to loud noise for a long time can be very harmful
to health. It can lead to heart and blood vessel problems, mental health issues, trouble
sleeping, and hearing loss. Noise pollution has a negative effect on the brain and nervous
system, and it can cause many problems. High-frequency noise, in particular, can disturb the
central nervous system. This can lead to problems like poor concentration, more anxiety, and
feeling mentally tired. Many studies around the world have shown that noise levels of ≥85 dB
at work increase the risk of noise-induced hearing loss (NIHL) and tinnitus.In Ulaanbaatar,
environmental noise pollution continues to grow due to population growth, construction, and
urban planning. Therefore, it is important to find out whether environmental noise pollution is
linked to mental and behavioral disorders, insomnia, nervous fatigue, high blood pressure,
and hearing loss among the population.
Goal:
The aim of this study is to examine the prevalence of primary hypertension (I10), nervous
fatigue (F48.0), sleep disorders (F51.0), and tinnitus (H83.3) caused by environmental noise
among the population of Ulaanbaatar.
Materials and Methods:
A descriptive research design was applied to examine statistical data from the Center for
Health Development regarding diseases related to noise pollution. Based on the 10th revision
of the International Classification of Diseases (ICD-10), the study focused on conditions such
as neurasthenia (F48.0), non-organic sleep disorders (F51), primary hypertension (I10), and
hearing disorders (H83.3). The analysis included data recorded between 2014 and 2023
among the population of Ulaanbaatar city. Epidemiological analysis was performed using
SPSS-24 software, and the results were calculated per 10,000 population.
Ethical Considerations:
This study did not receive any external funding or financial support from public or private
organizations. It utilizes secondary data from the Health Development Center, which does
not contain any personal information.
Results:
In 2014, the average age of individuals diagnosed with neurasthenia (F48.0) was 40.1±12.6
years; for non-organic sleep disorders (F51.0), it was 48.1±14.5 years; for noise-induced
hearing disorders (H83.3), 47.2±12.7 years; and for primary hypertension (I10), the average
age was 59.0±11.4 years. By 2023, the average age for primary hypertension had slightly
decreased to 58.0±12.9 years. Since 2014, the number of cases of nervous fatigue, non
organic sleep disorders, and hearing problems caused by noise has risen in Ulaanbaatar.
In 2023, the average age of people with primary hypertension (I10) dropped to 58.0±12.9
years. Noise-related illnesses are common among people aged 40 to 60 in Ulaanbaatar, and
this is lowering their quality of life.
Conclusion
Noise-related illnesses are being recorded among the 40–60 age group in Ulaanbaatar,
which is negatively affecting their quality of life. It is urgently necessary to introduce
measures for adequate protection of the population from the negative health effects of
environmental noise.
7.Results of the study on pathogens in vaginal smear tests

Mongolian Medical Sciences 2024;208(2):3-7
Introduction:
Although bacterial vaginosis prevalence varies across countries and populations, recent systematic
reviews and meta-analyses indicate that 23–29% of women of reproductive age are infected. Each
year, 21.2 million (22.9%) women between the ages of 14 and 49 in the United States develop bacterial
vaginosis. Microenvironments are interconnected with the endocrine, immune, and other organ
systems and dependent upon external and internal environmental influences. In women between the
ages of 15 and 44, bacterial vaginosis is the most common vaginal disorder, according to the Centers
for Disease Control and Prevention.
In our nation, 93.4% of women who are of reproductive age have vaginalis; the percentage of cases
with Gardnerella vaginalis alone is 22.6%, and 53.1% have it in combination with other anaerobic
bacteria, which is a significant percentage. Our research is based on the lack of information about the
vaginal environment of Mongolian women and factors influencing changes in the microenvironment.
Our research is based on the lack of information about the vaginal environment of Mongolian women
and factors influencing changes in the microenvironment.
Goal:
The objective is to study how age relates to the development of bacterial and fungal vaginitis through
the analysis of vaginal swabs.
Materials and Methods:
For our study, we selected 100 women aged 20-59 through targeted sampling from clients who
underwent vaginal smear tests at “Yu Bi Lab” laboratory and “Tsetsuu” diagnostic center in Ulaanbaatar
in 2023. Vaginal smear analysis was conducted using Nugent’s criteria and Gram staining. Statistical
analysis was performed by comparing pathogens among the participants based on age using
Pearson’s correlation method. We obtained permission to conduct research.
Through the Etugen University Biomedical Ethics Comittee convention held on march 11,2024
Results:
The study divided 100 women into four age groups to examine the vaginal environment with their age
and the factors influencing it. The research aimed to understand how bacterial vaginitis and fungal
vaginitis evolve during reproductive age and menopause. Among the age groups, women aged 20-29
had an average of 5.59±3.35 epithelial cells (n=32), those aged 30-39 had 6.10±3.29 (n=37), women
aged 40-49 had 6.70±3.90 (n=17), and women aged 50-59 had the highest number of epithelial cells
at 9.42±8.19 (n=14), representing 34% of the group.
Conclusion
1. Women of reproductive and menopausal age experience changes in the vaginal environment due to
various factors. This includes a decrease in the ratio of normal microorganisms and lactobacilli, an increase in the number of conditional pathogens, and the development of an alkaline environment
in the vagina.
2. Bacterial vaginitis predominantly affects younger women, with symptoms often being subtle. In
contrast, fungal vaginitis is more common among menopausal women. Lower estrogen levels in
women in this age group cause lactobacilli to break down glycogen less efficiently into lactic acid,
even though the number of lactobacilli is still normal. This research implies that suppositories and
estrogen pills may help treat these problems for women between the ages of 40 and 59.

Oyun B ; Uyanga B ; Burmaajav B ; Uranshagai N
Mongolian Medical Sciences 2024;210(4):45-52
Background:
Toxoplasmosis is an infection caused by the parasite Toxoplasma gondii. Cats are the
reservoir of the parasite. Humans can become infected either by ingesting the cysts (by
direct contact with cats or through food or water contaminated by cat faeces) or by eating
poorly cooked meat containing cysts. We aimed to study on knowledge, attitude, risk of
Toxoplasmosis among herder in Khovd province.
Materials and Methods:
Study methods: The study used a descriptive cross-sectional design and included herders
from Bulgan, Buyant, Darvi, Zereg, Myangad, Khovd, Erdeneburen, Jargalant soum, which
have the largest livestock number in Khovd province. A questionnaire was administered to
determine the knowledge, attitudes, and risk factors for toxoplasmosis among herders.
Study ethics:
Before starting the study, the methodology was discussed at a meeting of the
Ethics Committee of “Ach” University of Applied Sciences, and the research (Resolution No.
23/02) was approved.
Data processing:
The data collected during the study were coded into Microsoft Office Excel
and a database (file) was created. Open Epi Info and SPSS 20 were used to statistically
process the results of the study (mean, standard deviation, relative risk).
Result:
In result, 180 herder’s average age was 48.1±17.8 years old, most of them were female.
Most of herder were herding their livestock over six years. During their herding period, 31%
of herder household has registered rabies, anthrax, brucellosis, swine fever, blood infection,
blindness, smallpox, horse pox, scabies, foot and mouth disease among their livestock. By
questionnaire, toxoplasmosis has not registered among livestock. When assessing self
protection practices when dealing with suspected infected animals, 14-22.3% use masks
and aprons when dealing with sick animals, 1.4-3% use goggles, coveralls, and disinfectants,
and the lowest percentage is 0.2% of gloves. This indicates a very high risk of transmission
of zoonotic diseases among herder of Khovd province.
Conclusion
In our study, although no cases of toxoplasmosis were recorded among
livestock in the soums of the Khovd province by questionarie, the lack of self-protection
practices and attitudes against animal-to-human transmission and the high risk of infection
indicate the importance of disseminating information and organizing training on zoonotic
diseases
9.Predictive risk factors of early and late outcome after breast augmentation surgery
Innovation 2021;15(1):32-37
Background:
In 716 Mongolian patients who had breast augmentation surgery at Perfect
Clinic during 18 years. The purpose of this study evaluates Mongolians predictors of early and late
outcome after primary breast augmentation surgery.
Aims of study:
In this study, we aimed to clarify predictors of early and late outcome after breast
augmentation surgery.
Methods:
We selected patients who underwent breast augmentation implant surgery between
1999 and 2017. Development of hematoma was chosen for measure of early outcome and
capsule contracture was chosen for measure of late outcome. Multivariable Cox proportional
hazard regression and Kaplan-Meier estimations were used to clarify independent relationship
between possible predictors and outcomes.
Results:
A total of 716 patients were chosen and mean age was 32±7 years old. Hematoma was
occurred in 43 patients (6%) and median time to hematoma was 3 days (IQR 1; 7).). According
to the univariable analysis, every 1 year experience was associated with 9% decreased risk of
hematoma development. (HR=0.91, 95% CI 0.84-0.99, p<0.05). Finally, Kaplan-Meier estimation
was showed that hematoma free survival is higher in more experienced years and patients who
had subpectoral muscle.(log rank p<0.01 and p<0.001, respectively).
Capsule contracture was occurred in 38 patients (5.3%) and median time to capsule contracture
was 10 months (IQR 3; 27). According to the univariable analysis, every 1 year increase of surgical
experience is related to 9% decreased risk of capsule contracture (HR=0.81, 95% CI 0.75-0.88,
p<0.001), and more textured implant type is associated with less capsule contracture (HR=0.47,
95% CI 0.34-0.66, p<0.001).
Multivariable hazard regression was revealed that implant type (HR=0.55, 95% 0.33-0.90, p<0.05)
and surgical time (HR=1.00, 95% CI 1.00-1.01, p<0.001) were independently associated with
capsule contracture after breast augmentation surgery (Table 4). Kaplan-Meier estimation was
determined that capsule contracture free survival is higher in more experienced years and
patients who had more textured implant and subpectoral muscle implant (log rank p<0.001,
p<0.001 and p<0.001, respectively).
Conclusions
For breast augmentation surgery, implant type is independent predictor of capsule
contracture and surgical experience is predictor for both hematoma and capsule contracture.
Therefore, above mentioned predictors should be considered to prevent complications related
to breast augmentation implant surgery.

The main goal of this study is to examine the development of auditory perception performances of a cochlear implanted child who receive auditory verbal therapy.
Present study included a child with prelinguistic hearing loss who received cochlear implant at the Department of ENT, 1st State Central Hospital and enrolled in Auditory Verbal Therapy (AVT) in the Speech Therapy Unit of “ Aid” Clinic. This hearing impaired child participated in auditory verbal therapy with their mother and/or father for 5 months, and the family was given training programs to apply at home after each therapy session. The auditory perception performances of a child were evaluated before implantation and after: twice every week in total 32 Audio-Verval Therapy sessions were performed with the help of Medel LittlEars Auditory Questionnaire, LIP (Listening Process Profile), Ling’s Five Sound Test, the Multiple Frequency Animal Sound Test (mFAST) and MTP (Monosyllable and Polysyllable Test).
The auditory perception performances of a child joining auditory verbal therapy programs increased after 5 months of implantation. According to the Ling’s test all 5 sounds are determined (20-60dB) in 1m distance, but discrimination is observed in frequency range between 40-60 dB for sounds “A”, “U” and “M”.
Parents active participation as well as full attendance in the AVT treatment shows progress in auditory development of a child. Furthermore evaluation and data analysis is needed.
