Background: Pediatric diarrhea is one of the most common diseases among children and is the second leading cause of death and the third most prevalent disease among children worldwide. In Traditional Medicine, pediatric diarrhea is considered to result from an imbalance of the three bodily principles. In the treatment of this condition, Indra-4 decoction, which is traditionally used for its antipyretic and antidiarrheal effects, is commonly administered. Aim: To evaluate the clinical efficacy of Indra-4 in the treatment of pediatric diarrhea. Materials and Methods: A quantitative, randomized, controlled (active-control), open-label, single-center clinical trial was conducted. A total of 150 children were enrolled based on a confidence level of P>0.90 and a margin of error of D=10%, and were randomly assigned to two groups in a 1:1 ratio. The treatment group received Indra-4 decoction at a dose of 1.5 g twice daily for children aged 2–5 years and 2 g twice daily for children aged 6–9 years. The comparison group received montmorillonite powder at a dose of 2 g three times daily. Treatment was administered for 7 days in both groups. Clinical symptoms were scored and assessed before treatment, on days 3 and 5 of treatment, and after completion of treatment, and the results were compared between the two groups. The study was conducted with the approval of the Research Ethics Review Committee of the Mongolian National University of Medical Sciences, Mongolia (Approval No. 2026/1-01, January 23, 2026). Result: No statistically significant differences were observed between the two groups in terms of age, sex distribution, or total symptom scores at baseline (p>0.05), indicating that the groups were comparable. On days 3 and 5 of treatment and after treatment, the total symptom scores in the Indra-4 group were significantly lower than those in the comparison group (p<0.001). The overall treatment efficacy was 92.0% in the Indra-4 group and 78.7% in the comparison group, with a statistically significant difference (χ²=4.315, p=0.038). The percentage reduction in symptom scores was 90.97±4.14% in the Indra-4 group compared with 61.32±5.24% in the comparison group (t=28.072, p<0.001). These findings suggest that Indra-4 decoction may be more effective in reducing symptoms and improving treatment outcomes in children with diarrhea. Conclusion The results demonstrated that the Indra-4 group had significantly greater improvement in the major and accompanying symptoms of pediatric diarrhea, as well as higher overall treatment efficacy and recovery rates, compared with the comparison group. Indra-4 appears to be effective in the treatment of pediatric diarrhea and may be suitable for clinical use.

Background: Pulmonary alveolar proteinosis (PAP) is a rare lung disorder characterized by the accumulation of surfactant within the alveoli, leading to impaired gas exchange and respiratory insufficiency. Although the disease is uncommon, it significantly affects patients’ quality of life and requires specific diagnostic and therapeutic approaches. Whole lung lavage (WLL) is considered the standard treatment; however, it has not been widely implemented in Mongolia. We report the first successful case of WLL performed for PAP in Mongolia. Case Presentation: A 56-year-old male presented with dyspnea. Chest computed tomography demonstrated a bilateral “crazy paving” pattern. Bronchoalveolar lavage fluid was positive for periodic acid–Schiff (PAS) staining, and anti–GM-CSF antibodies were detected, confirming the diagnosis of PAP. WLL was performed under general anesthesia using a double-lumen endotracheal tube with bronchoscopic guidance. One lung was ventilated with 100% oxygen while the contralateral lung was sequentially lavaged with 800–1000 mL of warm (37°C) saline per cycle until the effluent became clear. A total of approximately 20 liters of saline was used. Result: The procedure was completed successfully without complications. Following treatment, the patient showed marked clinical improvement with reduced dyspnea and increased exercise tolerance. Oxygen saturation improved from 88% to 93%, and spirometric parameters (FVC, FEV₁) demonstrated improvement. Chest imaging revealed a reduction in pulmonary opacities. Conclusion This case demonstrates the successful implementation of whole lung lavage (WLL) in Mongolia and highlights its importance in improving the diagnostic and therapeutic capacity for rare pulmonary diseases such as pulmonary alveolar proteinosis. The procedure resulted in significant improvement in clinical, functional, and radiological parameters, consistent with findings from international studies. Early diagnosis of PAP and the adoption of standardized protocols in accordance with international guidelines are essential to optimize treatment outcomes and enhance patients’ quality of life.

Background: Herbal teas are rich in bioactive compounds with antioxidant, anti-inflammatory, and hepatobiliary supportive properties. Despite their long-standing use in Mongolian traditional medicine for liver and gallbladder health, comprehensive scientific data regarding the specific chemical composition and antioxidant activities of these polyherbal formulations remain limited. Aim: To evaluate the bioactive compound content and antioxidant activity of a polyherbal tea formulation for supporting liver and gallbladder function, with a focus on the influence of solvent concentration. Materials and Methods: The study utilized a polyherbal tea consisting of five plant species: Achillea asiatica Serg., Thalictrum foetidum L., Zygophyllum potaninii Maxim., Tanacetum vulgare L., and Rheum undulatum L. Samples were extracted using 30% and 70% ethanol. Preliminary phytochemical screening was performed using thin-layer chromatography (TLC). Total phenolic content (TPC) was determined using the Folin-Ciocalteu method, and total flavonoid content (TFC) was measured via the AlCl3 colorimetric assay. Antioxidant capacity was assessed through DPPH, ABTS+ and FRAP assays. Results: Phytochemical screening identified flavonoid derivatives, glycosides, and terpenoids in both extracts, while alkaloids were not detected. Quantitative analysis showed that the 70% ethanolic extract contained significantly higher levels of total phenolics (5.518±0.24%) and total flavonoids (1.513±0.023) compared to the 30% extract (p < 0.05). The 70% extract also demonstrated superior antioxidant potency, with lower (IC50) values for DPPH (55.37 µg/mL) and ABTS (86.08 µg/mL). Additionally, the FRAP assay confirmed the 70% extract had substantially higher reducing power (1440.84 µM Fe²⁺/L). Conclusions 1. Phytochemical analysis confirmed that the polyherbal tea is primarily composed of flavonoid derivatives, glycosides, and terpenoids. The total phenolic and flavonoid contents in the 70% ethanolic extract were significantly higher (p < 0.05) than those in the 30% extract. 2. The free radical scavenging activity evaluated by DPPH (IC50) 55.37 µg/mL) and ABTS (IC50) 86.08 µg/mL) assays indicated that the 70% ethanolic extract possesses markedly stronger antioxidant activity compared to the 30% extract. 3. The iron ion reducing power (FRAP: 1440.84 µM/L) showed a concentration-dependent linear relationship. The positive correlation between polyphenol content and antioxidant activity confirms that this herbal formulation has a scientific basis for its traditional use in supporting liver and gallbladder function.

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.

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.
