BACKGROUND. In the worldwide every 40 seconds one person takes their life, annually 1
million people die on Earth by the means of suicide. Regardless of gender it is one of the
main 3 causes of death in the population aged between 15-29. There have a tendency
to increase of suicide rates with each passing year in the Mongolia. Therefore, our study
goal is to determine the utilized methods and to identify some of the factors influencing
the escalation of this phenomenon. The data and materials were gathered by quantitative
research method from the post-mortem examination reports provided from the
central archive of National Institute of Forensic Science according to the descriptive
research design.
The fact that the bulk of the increasing suicide cases might be attributed to the unemployed
and working-age men without any chronic illnesses suggests correlation with
gender and socio-economic status.

BACKGROUND. Chronic rhino-sinusitis (CRS) is a common inflammatory disease of the
nose and paranasal sinuses, especially after virus infections. It has a significant impact
on patients’ quality of life. We aimed to evaluate the clinical value of low-level laser
therapy (LLLT) forpediatric chronic rhino-sinusitis.
METHODS. 30 patients 6-15 years old with CRS were divided into two groups: T1 were
treated twice a week and T2 were treated five times a week for 2 treatment sessions
within 2 weeks. Laser irradiation was delivered on 12 points over each maxillary and
frontal sinuses with 30 seconds and the total treatment duration was 180 seconds. The
evaluation was performed by a total symptom score based on SNOT-22 questionnaires
of pre and after treatments.
RESULTS. The total symptom scoreimproved significantly (p<0.15) in 27 cases.
CONCLUSION. This study indicates that LLLT applied for 4 weeks improves symptoms in
patients with CRS. LLLT is one of the most cost-efficient and painless treatment methods
for pediatric rhino-sinusitis.

Background:
Treatment of adult tibiofibular fractures, especially severely comminuted
fractures, is technically challenging due to the lack of reduction markers and difficulty in restoring
the alignment. Fixation of the fibula can facilitate reduction of the tibia fracture and restoration
of the lower extremity alignment.
Methods:
Between 2018-2019 we have operated on 50 patients who have lie on the same
plane of tibiafibular fractures. Measures of angulation were obtained from radiographs taken
immediately after the surgery, a second time 3 months later, and at 3-month follow-up. The
analysis was performed with STATA.
Results:
Fixating fractures of tibia and fibula at same level were not shown to have complications
on the development of nonunion including fibular shortening, hindfoot alignment, slow process of
nonunion and unstableness.
Conclusions
We recommend fibular fixation in all 50 distal fractures when both fractures lie on
the same plane and the tibial fracture is relatively stabilized.

Introduction:
Air pollution has become one of the major problems in socio-economic and health
issues in Mongolia. Among the various hazards of particulate matter (PM) pollutants, microorganisms
in PM2.5 and PM10 are thought to be responsible for various allergies and for the spread of respiratory
diseases. Recent studies have shown that PM2.5 particles can cause chronic heart failure, heart
arrhythmias, and strokes, as well as lung damage, cirrhosis, inflammation, cancer, cardiovascular
disease, and metabolic disorders. Furthermore, some studies have concluded that PM2.5 particles
in the environment are a risk factor for gastrointestinal, liver, colon, and lung cancer as well as it
affects the growth and metastasis of various cancer cells caused by other factors. In our country, the
health effects of air pollution and the relationship between the pathogenesis of cancer research are
scarce. Therefore, the study of the effects of PM2.5 particles on cancer cell proliferation, migration
(metastasis) can provide a significant role for cancer treatment, diagnosis, and prevention.
Purpose:
Determining the effects of PM2.5 particles on cancer cell proliferation, migration (metastasis)
in in-vitro
Material and Methods:
A human liver cancer cell line (HepG2), human gastric cancer cell line (AGS)
were obtained from the central scientific research laboratory in the Institute of medical sciences.
HepG2, AGS cells were seeded at a concentration of 1*105 cells/mL in a culture flask and cultured
in RPMI-1640 medium supplemented with 10% FBS, 1% antibiotic mix (penicillin, streptomycin) in a
humidified atmosphere of 5% CO2 at 37 °C. The cytotoxic effect of PM 2.5 in AGS, HepG2 cells were
evaluated by MTT, CCK8 assays. AGS, HepG2 cells were incubated in 96 well plates for 24h then
treated with different concentrations (0, 5, 10, 25, 50 and 100 μg ) of Bayankhoshuu, Buhiin urguu,
and Zaisan samples for 24h, respectively.
Results:
Concentrations of 10, 25, and 50 μg/ml of samples collected from the Bukhiin urguu and
Zaisan in March increased HepG2 cell growth, while doses of 25, 50 μg/ml of samples collected from
Bayankhoshuu in March and December increased HepG2 cell growth. Therefore, concentrations of
25 and 50 μg/ml of samples collected from Bayankhoshuu in March increased AGS cell growth, while concentrations of 25, 100 and μg/ml of samples collected in December increased AGS cell growth.
However, no cytotoxic effect was observed in the sample collected from Zaisan in March, whereas
the PM2.5 sample enhanced AGS cell growth in dose dependent manner in December.(p <0.05)
Conclusion
High levels of heavy metals were detected in samples collected in December from
Bayankhoshuu, Bukhiin urguu and Zaisan of Ulaanbaatar. Concentration of 25 μg/ml of samples
collected from the Bukhiin urguu and Zaisan in March increased HepG2 cell growth. Concentrations
of 25 μg/ml of PM2.5 collected from three regions around Ulaanbaatar increased HepG2 and AGS
cell migration.
