The Mongolian plants considered to possess medicinal properties may contain novel compounds since they are exposed to severe conditions; such plants could become good candidates for modern drug discovery programs. Daurian Thermopsis (Thermopsis lanceolata R.Br.= Th.dahurica Czefr.), Gobian Thyme (Thymus gobicus Tschern.) and Mogilev Mallow (Malva mohileviensis Downer) are separately used as mucolytic and anti-inflammatory treatment in non-conventional medicine. Therefore, weprepared extract of these herbals compound called as a Tetima and to evaluate it’s acute toxicity. It isimportant to produce mucolytic effective new pharmaceutical preparation used for upper and lowerrespiratory tract inflammatory disease.Tetima herbal compound extract was prepared in ethanol, the ratio of herbals to ethanol was 1:10. Healthy 25 white albino mice (male weighing between 17-30 gram) used in this study. They were kept in large airy cages in groups of 5 animals per cage with free access to food and water. Five doses (8-20 g/kg) were then chosen for the determination of intraperitoneal LD50 in mice and given to five groups of albino mice. The animals were observed for first 2 hours and then at 6th and 24th hour for any toxicsymptoms. After 24 hours, the number of deceased mice was counted in each group. The percentage of animals that died at each dose level was transformed and then LD50 determined by the methods of Karber and Pershin.G.N.The LD50 of Tetima herbal compound in mice was determined to be 14.3 g/kg after intraperitonealinjection. There was no difference occurred between Karber and Pershin methods to evaluate acute toxicity. In the animals receiving intraperitoneal injection, the abdominal muscle contractions and ataxia was observed, which persisted for few hours. At the 6th hour they were drowsy and less responsive. The severity of these effects was related to the level of dose. However, at 24th hour most of the survivors had recovered from these symptoms.Tetima herbal compound extract is a relatively safe, particularly when given intraperitoneal inject toexperimental animals.

Introduction:
Endometritis (EMM) is the most common maternal infectious complication of childbirth, occurring
more commonly after low transverse cesarean section (LTCS) than vaginal delivery [1]. In a Cochrane
review, the mean incidence of EMM following elective cesarean section was 7% and after non-elective
or emergency operations was 30% [4]. A variety of independent risk factors for post-cesarean EMM
have been identified in previous studies, including no prior cesarean section [5], low infant Apgar
scores [6], trial of labor [7], premature rupture of membranes (PROM) >24 hours, young maternal
age [8], preterm or post-term gestation [9], antepartum infections [10], pre-eclampsia, meconium [11],
amnion infusion, postpartum anemia, multiple vaginal examinations [12], and manual removal of the
placenta [13]. The time of ruptured membranes before delivery is examined via dichotomized time
thresholds, the risks of chorioamnionitis and endomyometritis are significantly increased at 12 hours
and 16 hours, respectively [16, 17]. A change in policy to administer prophylactic antibiotics before
skin incision led to a significant decline in postcesarean delivery surgical-site infections [18, 19].
Objective:
To determine independent risk factors for EMM following (LTCS).
Material and Method:
The study was case-control study, between 2022 to 2023 years at the “Urguu” specialized maternal
hospital Ulaanbaatar, Mongolia. Case group has 101 women with EMM and the control group has 100
women with non EMM after LTCS.
Results:
The age of 2 study groups was 32.4 and 32.8, body mass index was 30 kg/m2 and 30.7 kg/
m2.Young maternal age <25 has a 22% (p=0.001, OR=4.5) influence on the occurrence of EMM.
Other pregnancy related factors were not associated with the EMM after LTCS. (p>0.05). Delivery
risk factors has increases the EMM by 15% (p=0.002), labor induction by 20% (p=0.001), duration of
labor >12 hours by 40% (p=0.001), PROM increased by 15% (p=0.005), meconium by 15% (p=0.005),
chorioamnionitis by 15% (p=0.001).
Conclusion
Our study, young maternal age <25 has influence on the occurrence of EMM. Other pregnancy related
factors were not associated with the EMM after LTCS. Delivery associated risk factors are affected
by the EMM after LTCS. The labor after LTCS, labor induction, PROM >12 hours, duration of labor,
number of vaginal exams>4, meconium, chorioamnionitis increased by EMM. Young maternal age
(<25) increased the risk of EMM attached with labor association risk factors.

Background:
Meniere's disease is a condition caused by disturbances in the
auditory and vestibular systems. It is characterized by symptoms such as dizziness,
nausea, vomiting, and tinnitus. In the United States, the prevalence of
Meniere's disease has been found to be 84 cases per 100,000 women and
56 cases per 100,000 men. Regionally, it is more common in less populated
areas, and research has confirmed that the prevalence increases with higher
household income.
Aim:
To evaluate the effectiveness of traditional medicine treatments and therapies
for Meniere's disease.
Results:
The patient is a 43-year-old male, with symptoms of dizziness, vomiting,
and tinnitus. Since 2023, he has sought care at the Central Hospital of
Mongolian Medicine, where he received traditional medicine treatments including
herbal therapy and other traditional therapies on three occasions. As a
result, the frequency of dizziness has decreased and other clinical symptoms
have improved.
Conclusion
Traditional medicine treatments have been shown to be effective
in managing Meniere's disease by extending the interval between relapses,
improving quality of life, and significantly reducing clinical symptoms.

Background:
Membranous nephropathy (MN) is among the most common causes of nephrotic syndrome in adults. MN
is diagnosed in one third of cases of nephrotic syndrome on kidney biopsy. Kidney biopsy is the gold standard for diagnosing
MN and plays an important role in determining the severity of the disease and in determining treatment decisions
and regimens. Therefore, the lack of research on kidney biopsy in Mongolia is the reason for this study.
Aim:
The aim of this study was to investigate the pathological features in the kidney tissues of patients with primary
membranous nephropathy diagnosed by kidney biopsy.
Materials and Methods:
A retrospective study was conducted on 51 cases of MN diagnosed in kidney biopsies performed
at the First Central Hospital of Mongolia (FCHM) over a period of 12 years. Renal function was calculated using
the CKD-EPI (2021) formula and classified into the stage of CKD by eGFR. Histopathological findings were examined
using 4 light microscopy (LM) stains (Hematoxylin-Eosin, Masson-Trichrome, PAS, and Methenamine silver staining)
and 8 immunofluorescence (IF) microscopy stains (IgG, A, M, complement C3, C4, C1q, and kappa, lambda). The study
excluded secondary MN based on viral markers, tumor markers, and serological tests. Statistical analysis was performed
using SPSS and STATA 15.0 software, using t-tests, Pearson’s chi-square tests, and multiple group comparisons were
performed using ANOVA and Kruskal-Wallis methods. The study design was approved by the Ethics Committee of the
MNUMS, Mongolia. (№ 2023/3-07)
Results:
A total of 305 kidney biopsies performed at the Kidney Center of the FCHM between 2011 and 2023 resulted in
the diagnosis of 51 cases of primary MN. The mean age of patients with membranous nephropathy was 40.6±9.3 years,
with the oldest age of 65 and the youngest of 22 years, and 36 (70.59%) were male and 15 (29.41%) were female. In the
kidney biopsy, the average number of glomeruli was 16.51±7.82 (min-max, 3-54), and by LM, 33.3% showed global
sclerosis of glomeruli by hematoxylin-eosin staining, 94.12% showed thickening of the glomerular basement membrane
(GBM), 31.2% showed double counter staining of subepithelial immune complexes by methenamine-silver staining,
88.24% showed holes in the GBM, and 54.9% showed spike-like changes by Masson-Trichrome staining. IF showed IgG
3+ in 37.3%, 2+ in 39.2%, 1+ in 13.7%, and trace staining in 9.8%, while 74.5% of the cases were positive for C3, 93.1%
for kappa, and 79.5% for lambda. LM showed thickening of the GBM (OR 23.5, 95% CI 0.093-0.53, p value= 0.007)
and interstitial fibrosis (95% CI 6.98-31.07, p value= 0.003) contributing to the decrease in eGFR. The mean time from
the onset of the first symptoms of kidney disease to the time of kidney biopsy was 35.35±61.54 months. Patients who
underwent biopsy later (in months) after the diagnosis of the disease had a higher incidence of interstitial fibrosis (74.6 ±
98.43, 95% CI -90.52-20.68, p value = 0.002).
Conclusion
The histopathological features of MN confirmed by kidney biopsy showed thickening of the GBM in
94.12%, global sclerosis in 33.3%, and holes in 88.2%. Immunofluorescence microscopy showed 100% IgG staining,
while C3, kappa, and lambda were positive in 74.5%, 93.1%, and 79.5%, respectively.

Background and Aims:
Hepatocellular carcinoma (HCC) is a common cause of cancer related death
in Mongolia. Early diagnosis is the very important management to increase successful treatment
and survival rate. Glypican-3 (GPC3) protein is highly expressed in hepatocellular carcinoma (HCC)
tissue and in serum of HCC patients. Recent studies have been conducted and suggested as a
diagnostic biomarker for detecting HCC in the early stage. Therefore, we investigated the diagnostic
value of the serum GPC3 level and compared it to the alpha-fetoprotein (AFP) level as a diagnostic
biomarker of HCC.
Methods:
We enrolled a total of 90 participants and divided into 3 groups with HCC (30), with liver
cirrhosis (LC/30) and healthy (30) as the control group (30). GPC3 and AFP serum (sGPC-3, sAFP)
levels were measured using commercially available enzyme-linked immunosorbent assay kits. The
diagnostic accuracy was analyzed using the receiver operating characteristics (ROC) curve and
estimated sensitivity and specificity of each biomarker.
Results:
sGPC3 was significantly elevated in the HCC group as compared to liver cirrhosis and
healthy subjects (658±138.2 pg/ml, 378±25.5 pg/ml, 356.3±29 pg/ml) respectively. sGPC-3 sensitivity
was 96.6% and specificity was 100%. The area under the ROC curve (AUC) for GPC3 was 0.999
(0.996- 1.0).
In comparison, the mean of AFP was significantly higher in HCC (16.9±11.7 ng/ml) than in LC (6.7±7.6
ng/ml) and in healthy subject (3.3±2.1 ng/ml) and AFP sensitivity was 43,3 %, specificity was 95 %
with an AUC of 0.808 (0.696- 0.921).
The combination of GPC-3 with AFP achieved the highest sensitivity (97.1%) and specificity (97%).
Conclusion
Serum GPC3 has a higher sensitivity than AFP for the early diagnosis of HCC.
Combination of two markers showed greatest diagnostic accuracy.

Research of function of vitamin D on immune system has been studying since the study revealed
that vitamin D receptor is expressed on the surface of the immune cells. 1,2-dihydroxyvitamin
D3 [1,25(OH)2D], physiologically active form, can be generated through hydroxylation of
25-hydroxyvitamin D3 [25(OH)D], inactive form of vitamin D, in a liver, connecting with specific VDR
make biological action. Vitamin D make different biological actions depends on connecting with
different immunological cells. Some studies indicated that Vitamin D plays pivotal role in antibacterial
innate immune responses through regulating reaction of the main cells as macrophages and dendritic
cells. Moreover, calcitriol, the active form of vitamin D, is connected with VDRE, modulates the innate
immune response through directly inducing expression of catelicithin and β-defensin as antimicrobial
peptides, reducing secretion of IL-1b, IL-6, TNF-a, RANKL, COX-2 as proinflammatory cytokines and
increasing production of IL-10, an anti-inflammatory cytokine. Vitamin D plays in proliferation and
differentiation of T and B cells and regulates the activities of over 500 genes. Vitamin D differently
impacts on per se stages of T cells’ proliferation. Vitamin D indirectly mitigates the differentiation from
immature B cells to plasma B cells while it directly impacts on regulation of overloaded production of
antibodies in plasma B cells. In conclusion, vitamin D modulates the innate- and adaptive immune
response through regulation on activation of APCells, proliferation and differentiation of immune cells,
secretion of some antibacterial peptides.

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.
