Background
Diabetes is a metabolic disorder that is characterized by chronic high blood glucose levels that causes
complications in the eyes, kidneys, heart, vessels and nerves. Currently diabetic nephropathy is the
most significant long-term complications in terms of morbidity and mortality for individual patients
with diabetes. Honey bee venom can be considered as a natural remedy for diabetes due to its blood glucose levels lowering and lipid-regulating effect on diabetic rabbits.
Aim
The aim of this study was to investigate the effect of Mongolian honey bee venom (Apis mellifera) on renal dysfunction in alloxan induced diabetic rabbits.
Material and Method
Twenty two Chinchilla rabbits were divided into three groups: control (n=6), diabetic (n=8), and bee venom treated (n=8). The diabetic group was injected with 5% solution of Alloxan monohydrate 100 mg/kg intravenously behind the ear for 2 minutes to induce diabetes. The bee venom treated group received a bee sting (a sting contains 0.2-0.5 ml of bee venom) on their hind paw every day after their diagnosis of diabetes.
Result
Bee venom treatment (BVT) led to the following changes: compared to the diabetic group, the bee venom treated group’s blood glucose levels lowered between 14.9% and 26.5%; the plasma creatinine and urea levels were decreased respectively by 19,8% and 14.8%. Blood urea nitrogen (BUN) levels were reduced by 14.8%.
Conclusion:
Treatment with Mongolian bee venom lowered the blood glucose levels and prevents the renal dysfunction in alloxan induced diabetic rabbits

Introduction
In 19th century, researchers proved at biochemical level the healing properties of bee products such as bee venom, honey, royal jelly, pollen, propolis and wax. The object of our research is the Apis cerena’s venom properties1-2.
Asiatic honey bee or Apis cerana is small honey are small honey bees of southern and southeastern Asia, such as China, India, Japan, Malaysia, Nepal, Bangladesh and Papua New Guinea3. This species is also known as the Himalayan hive honeybee. This species is the sister species of Apis koschevnikovi, and both are in the same sub¬genus as the Western (European) honey bee, Apis mellifera4.
Goal
The purpose of our research is to study property and potential of bee venom and its effect on immune system. Heal¬ing property of Apis cerana was high. This study proves that bee venom therapy stimulates immunity.
Materialis and Methods
The research was conducted at the Scientific Research Center of “Monos” Institute of Traditional Medicine and in biochemical Laboratory of “Khuljborjigon” Clinic. For the experiment, we used 23 perfectly healthy mice of same sex and size which meets standards of laboratory testing.
We put a bee sting to 0.5 ml of 10% red blood cell (RBC) solution and measured time of heamolysis to de¬fine bee venom potential/capability by Shkenderov S., Ivanov Ts., (1985) method. Following Erne (1963), Kovalev I.E.,(1976), Petrov’s (1980) methodology of studying effects on immune system, we have stung bee venom to 23 mice on the acupuncture point of hind paw every other day in total 3 times. On third day of the experiment, we in¬jected into vein 2ml of 10 % sheep’s RBC to stimulate the immunity. On the fifth day, we defined weight of pancreas, number of pancreatic cells, pancreatic index, and haemagglutination titre.
Results
Potential of bee venom is determined by speed of heamolysis when bee sting is placed in the 0.5 ml of 10% RBC solution. If we place one bee sting into 1ml of RBC solution then the speed of heamolysis is 46 seconds, when two stings are place speed is 38 seconds and when 3 stings placed then time is 30. Compare to usual speed of heamolysis which is 60 seconds, change in time depending on the number of bee stings proves the effectiveness of bee venom (Table 1). In figure 3, the number of spleen cells of control group’s was 142.71±55.51*106/ml. this is 1.2 times lower compare to normal group which is 172.67±135.5*106/ml. BVT group’s number of spleen cells was 329.78±187.78*106/ml and 1.61 times bigger than in control group. In comparison to control group, haemagglutina¬tion titre of BVT group was 1.13 times higher (BVT group 54.86±19.95%; control group 50±8.83%, p<0.05) and this indicates that BV has immunity stimulating effect.
Conclusions
From our experiment we can conclude the following
1. Apis mellifera’s bee venom has high treating effect.
2. Bee venom therapy has immunity stimulating activity.

Background:
A drug related problem is defined by the Pharmaceutical Care
Network Europe Association as an an event or circumstance involving drug
therapy that actually or potentially interferes with desired health outcomes.
One critical aspect of preventing such errors is proper dose adjustment, which
plays a vital role in the diagnosis and treatment of disease. For instance, adjusting
the dose of warfarin based on the patient’s INR level is essential. In
a 1995 study conducted in England, clinical pharmacists recommended target
doses of angiotensin-converting enzyme (ACE) inhibitors for patients with
chronic heart failure. As a result, patients experienced a significant reduction
in pulmonary and peripheral edema, along with improved exercise test outcomes.
At the Mongolian-Japanese Hospital of the Mongolian Medical University
of Science and Technology, it is important to analyze dosage-related
issues identified by clinical pharmacists and inform healthcare professionals
about common dosage selection errors and associated risks.
Aim:
We analyzed issues related to medication dosage.
Materials and Methods:
A retrospective study was conducted to examine
problem related to dosage detected through prescription monitoring at the
Mongolian Japanese Hospital of the Mongolian National University of Health
Sciences from 2023 to 2024.
Results:
Out of a total of 2340 drug-related problem identified across five
inpatient wards during this period, 581 (100%) were related to dosage. Clinical
pharmacists performed prescription review on approximately 67% of all
inpatients, which was consistent between years. However, medication-related
problems tended to decrease from 41.1% (n=1499) in 2023 to 22.3% (n=841)
in 2024 (p=0.05). The majority of dose-related problems, 75.6% (n=440), were
overdoses. Medication-related problems were most common in the surgical
department, with 59.5% (n=346) (p=0.001). The most frequent dosage-related
errors involved exceeding the daily dose of diclofenac, administering higher-
than-recommended doses of ceftriaxone, failing to adjust cefotaxime for
renal function, and using inappropriate doses of metronidazole in patients with
impaired liver function. The leading cause of these errors was failure to adhere
to guideline-recommended dosing, which accounted for 71.3% (n=415)
of cases (p=0.001). When dosage-related recommendations were provided to
physicians before of treatment, acceptance rates increased by 14% (p=0.001).
These interventions resulted in an estimated cost saving of 1.267.219₮ and a
reduction of 363 injections.
Conclusion
Therefore, clinical pharmacist-led prescription review can help
reduce the risk of dosage errors, lower associated healthcare costs, and alleviate
the burden on medical staff.

Complete androgen insensitivity syndrome (CAIS), also known as Morris
syndrome, is a rare X-linked recessive disorder characterized by a
46XY karyotype and a female external phenotype. We present the case
of a 32-year-old patient who presented to Unimed International Hospital
in 2024 with primary amenorrhea, infertility, and chronic pelvic pain.
Clinical examination, imaging, and laboratory investigations led to the
diagnosis of CAIS. Laparoscopic surgery was performed to remove bilateral
gonadal structures and a cystic mass on the left side. Histopathological
analysis revealed testicular tissue and a serous cystadenoma
originating from the left mesonephric remnant. Following gonadectomy,
hormone replacement therapy was initiated, resulting in stabilization of
hormone levels. This rare case highlights the possibility of mesonephric
remnant-derived cystadenoma in CAIS and underscores the diagnostic
value of cytogenetic and histological evaluations, especially in distinguishing
between ovarian and testicular tissue when imaging findings
are inconclusive.

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.

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.

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:
Toll like receptors (TLRs) are a class of proteins that key role in the innate immune system. The SOCS1 and SHP2 proteins are negative-feed loop inhibitors of signaling of JAK/STAT and TLRs pathways.
Purpose:
To determine negative regulator protein activation which is activated through TLR7 ligand/IFN-γ signal transduction in endothelial cells.
Methods:
We used mouse aortic linear endothelial cell (END-D); protein expressio was detected by western blotting
Results:
We analyzed a time dependent stimulation effects of negative regulator proteins stimulated by TLR7 ligand/IFN-γ in endothelial cell cultures. Imiquimod of 10 μg/ml treatment of 1 hr was followed by 100 ng/ml IFN-γ stimulation for 1-8hr to analysis of negative regulator SOCS1 and SHP2 protein expression.
In untreated cells, there was low activations of negative regulator SOCS1 and SHP2 proteins. IFN-γ stimulation alone had increased SOCS1 and SHP2 protein expressions, also imiquimod treatment highly elevated SOCS1 and SHP2 expressions. However imiquimod and IFN-γ doubled treatment have decreased activation of negative regulator SOCS1 and SHP2 proteins. These findings suggest SOCS1 and SHP2 proteins are inhibitors in the TLR7 ligand/IFN-γ signaling.
Conclusion
Negative regulators, SOCS1 and SHP2 strongly suppressed activations of TLR7 ligand/IFN-γ signaling
