Background:
Traditional medicine has long utilized herbal and animal-derived materials worldwide, and traditional
formulations for the management of male sexual dysfunction continue to be actively investigated. This study aimed to
investigate the chemical composition and antioxidant effects of Anti-Impotence-4, an herbal–animal formulation, in an
experimental model of chronic stress-induced erectile dysfunction (ED).
Aim:
To investigate the bioactive compounds present in the plant- and animal-derived formulation Anti-Impotence-4 and
its effects against oxidative stress.
Materials and Methods:
Fifty-eight male Wistar rats were randomly divided into six groups, including healthy control,
disease control, reference, and treatment groups. Chronic stress was induced once daily for 56 days using a random stress
protocol, as described by Peng Zou (2019). Oxidative stress parameters were determined using ELISA. The chemical
constituents of the methanolic extract of Anti-Impotence-4 were analyzed using ultra-performance liquid chromatogra
phy–mass spectrometry (UPLC–MS) in both positive and negative ionization modes.
Results:
In an experimental model of erectile dysfunction induced by chronic stress, treatment with Anti-Impotence-4 led
to a dose-dependent attenuation of oxidative damage. Specifically, levels of the DNA oxidation marker 8-hydroxy-2′-de
oxyguanosine (8-OHdG) were reduced by 13.3–32.5% following administration of Anti-Impotence-4 at doses of 42,
84, and 210 mg/kg. Likewise, malondialdehyde (MDA) concentrations decreased by 7.9–23.7% at therapeutic doses
(p<0.05). In contrast, antioxidant defense mechanisms were markedly enhanced, as evidenced by significant increases
in superoxide dismutase (SOD) activity (34.1%, 38.1%, and 44.6%, respectively; p<0.05) and glutathione (GSH) levels,
which rose by 37.0–55.4%. Biological substances identified a total of 10 compounds, including six amino acids, flavo
noids, and iridoids, in the positive ion mode. In negative-ion mode, 18 bioactive compounds were detected, including
amino acids, carbohydrates, organic acids, fatty acids, flavonoids, and phenolic compounds.
Conclusion
Phytochemical analysis of the methanolic extract of the Anti-Impotence-4 formulation demonstrated the
presence of diverse bioactive constituents, including amino acids, purine derivatives, nucleosides, carbohydrates, organic
and fatty acids, flavonoids, phenolic compounds, and iridoids. In a chronic stress-induced erectile dysfunction model,
treatment with Anti-Impotence-4 significantly enhanced antioxidant defense by increasing superoxide dismutase and
glutathione levels, while markedly reducing oxidative stress markers such as 8-hydroxy-2′-deoxyguanosine and malond
ialdehe indicating significant antioxidant and protective effects.

Mongolian Journal of Health Sciences 2026;92(2):129-133
Background:
According to classical sources of Traditional Mongolian Medicine, the Mana-4 decoction clears internal heat and fever, alleviates febrile and infectious diseases, resolves pale-brown Badgan disorders, and alleviates severe pneumonia. Chimedragchaa.Ch. et al. (2002) demonstrated that Mana-4 possesses heat-clearing, anti-inflammatory, and immunomodulatory effects. Chronic Fatigue Syndrome (CFS) is a disorder characterized by clinical manifestations including physical exhaustion, low-grade fever, headache, mood fluctuations, cognitive impairment, and sleep disturbances. In recent years, as the pace of modern life and workload have increased, physical, psychological, and mental stress have intensified, leading to dysregulation of the nervous and endocrine systems, impaired immune function, and a rising global prevalence of CFS—a trend that has attracted increasing attention from researchers worldwide. However, the etiology and pathogenesis of CFS remain incompletely understood, and effective, evidence-based treatments continue to be sought. Therefore, we developed Immunoflu soluble granules, derived from the constituents of Mana-4, and this study aimed to investigate its anti-fatigue effects, as no such investigation had previously been conducted.
Aim:
To evaluate the anti-fatigue effect of Immunoflu, a formulation derived from the traditional Mana-4 decoction widely used in Traditional Mongolian Medicine.
Materials and Methods:
A chronic-fatigue rat model was established by forced-swimming induction, following the method of Jia Wang et al. (2013). The behavioral effects of Immunoflu were assessed using the open-field test (locomotor activity) and the elevated plus-maze test (anxiety-related behavior).
Result:
Immunoflu was administered at 100, 200, and 400 mg/kg to evaluate its effects in a chronic-fatigue model. In the open-field test, no significant difference (p>0.05) in central-zone entries was observed between Immunoflu and the model control. However, vertical locomotor activity increased significantly: Immunal 50 mg/kg +80.4% (p=0.024), Immunoflu 100 mg/kg +82.6% (p=0.003), and 200 mg/kg +77.4% (p=0.035). From these findings, Immunoflu at 100 and 200 mg/kg clearly enhanced locomotor activity in rats with chronic fatigue. In the elevated plus-maze test, Immunal 50 mg/kg increased the time spent in the central zone (10×10cm) by 53.3% (p=0.021) and in open arms by 61.4% (p=0.032) compared with the model control. Although Immunoflu produced no significant changes (p>0.05) in central-zone entries or time spent in the central zone, the time spent in the open arms increased by 60.6% at 200 mg/kg (p=0.026), indicating a reduction in anxiety and improved behavioral response to stress.
Conclusion
In a forced-swimming–induced chronic-fatigue model, Immunoflu increased locomotor activity by 77.4–82.6% at 100 and 200 mg/kg, reduced anxiety by 60.6% at 200 mg/kg, and reduced behavioral despair and fatigue by 35.3% at 100 mg/kg.

Mongolian Journal of Health Sciences 2026;96(6):145-150
Background:
Diabetes mellitus accounts for 42.9% of endocrine and nutritional metabolic diseases in Mongolia, with a prevalence of 111.4 cases per 10,000 population. This represents a 28.5% increase compared with the previous year (82.9 cases per 10,000 population in 2019), indicating a continuing upward trend in the prevalence of diabetes mellitus. In Mongolian traditional medicine, Sapparin tablets are used to treat blood disorders and liver diseases. The formulation contains four major herbal ingredients: C. jubata, C. sappan, Z. officinale, and H. rhamnoides.
Aim:
To study the effects of Sapparin in a high-fat diet and low-dose streptozotocin-induced diabetic model in experimental rats.
Materials and Methods:
We used 40 Wistar rats to establish a type 2 diabetes mellitus (T2DM) model according to the method described by Bailu Duan et al. (2017). The rats were fed a high-fat diet for 28 days, followed by an intraperitoneal injection of streptozotocin (STZ) at 35 mg/kg to induce T2DM. After STZ administration, Sapparin was orally administered to diabetic rats at 89 and 178 mg/kg for 21 days. At the end of the experimental period, insulin, GLUT4, superoxide dismutase (SOD), and glucagon-like peptide-1 (GLP-1) levels were determined using enzyme-linked immunosorbent assay (ELISA) according to the manufacturer’s instructions on days 14 and 21.
Result:
After 14 and 21 days of treatment, fasting blood glucose levels decreased by 33% and 22.5% in the Sapparin 89 mg/kg and 178 mg/kg groups, respectively, compared with the diabetic control group (p=0.05). In the glucose tolerance test, the 89 mg/kg Sapparin-treated group showed a 31% increase in glucose levels at the initial measurement compared with the diabetic control group, followed by decreases of 10% at 30 min and 30% at 120 min (p=0.04). Serum insulin levels in the 89 mg/kg Sapparin group decreased by 20% on day 14 and 19.8% on day 21 compared with the diabetic control group, while the 178 mg/kg group showed decreases of 15% and 20%, respectively, approaching the levels observed in the healthy control group (p=0.05). Furthermore, HOMA-IR decreased by 42–46% over time in both the 89 and 178 mg/ kg Sapparin-treated groups, with statistically significant differences observed (p=0.05).
Conclusion
In a rat model of type 2 diabetes mellitus, Sapparin reduced blood glucose levels, serum insulin levels, and insulin resistance (HOMA-IR), and may have a positive effect on lipid metabolism.

Mongolian Journal of Health Sciences 2026;93(3):171-177
Background:
Respiratory diseases remain among the top five leading causes of morbidity, with an incidence rate of 788.4 cases per 10,000 population in 2021. Among these, acute bronchitis accounts for 9.3%. According to international clinical guidelines for the diagnosis and treatment of adult acute bronchitis, symptoms usually resolve spontaneously within 1–3 weeks, but they considerably reduce the patient’s quality of life. Therefore, Colsaurin syrup, a new natural formulation with analgesic and anti-inflammatory effects, was clinically investigated to assess its efficacy and safety. The introduction of this domestically produced herbal medicine into clinical practice is expected to have both medical and socioeconomic significance by expanding the range of national pharmaceutical products.
Aim:
To evaluate the effect of Colsaurin syrup on the quality of life in adults diagnosed with acute bronchitis.
Materials and Methods:
This study was a randomized, double-blind, placebo-controlled clinical trial conducted among inpatients at Songinokhairkhan District General Hospital, Ulaanbaatar. Adult patients diagnosed with acute bronchitis (J20) who met the inclusion criteria and provided informed consent were enrolled. Participants were randomly assigned to either the Colsaurin or placebo group.
Result:
In the Bronchitis Severity Score (BBS) assessment, baseline mean scores indicated severe disease: 10.88±2.47 in the Colsaurin group and 10.67±2.16 in the placebo group. After treatment, scores decreased significantly to 3.50±1.41 (p<0.001) in the Colsaurin group and 5.00±2.24 (p=0.006) in the placebo group, indicating greater improvement in the Colsaurin-treated patients. In the Visual Analog Scale (VAS) assessment, the mean pre-treatment score for both groups was 7, corresponding to frequent cough, which decreased to 2 after treatment (p<0.05), representing a 28% reduction in coughing discomfort. In the Cough and Sputum Assessment Questionnaire (CASA-Q), the Colsaurin group showed a 3.25-point reduction after treatment, indicating a significant decrease in cough frequency and triggering factors (p<0.05).
Conclusion
1. In patients diagnosed with acute bronchitis (J20), treatment with Colsaurin syrup reduced disease severity by 30% and alleviated cough-related discomfort by 28% compared to baseline.
2. Moreover, patients reported improved sleep quality and work capacity, reflecting an overall enhancement in quality of life.
3. No adverse effects were observed in the Colsaurin treatment group.

Mongolian Journal of Health Sciences 2026;95(5):186-191
Background:
Chronic Fatigue Syndrome (CFS) is a poorly understood disorder of unknown etiology, characterized by clinical manifestations including physical exhaustion, low-grade fever, myalgia, dizziness, mood fluctuations, cognitive impairment, and sleep disturbances. CFS is highly prevalent and frequently comorbid with psychiatric conditions, particularly depression and anxiety. Symptoms exacerbate during physical or mental exertion and do not completely resolve with rest. Currently, there is a lack of proven, effective pharmacological treatments for CFS. Therefore, this study aimed to investigate the anti-fatigue effects of Immunoflu.
Aim:
To evaluate the anti-fatigue effects of Immunoflu, a technologically modernized formulation derived from the traditional Mana-4 decoction.
Materials and Methods:
A chronic fatigue rat model was established using the forced-swim protocol described by Jia Wang and Chengxin Sun (2013). The pharmacological effects of Immunoflu were evaluated by quantifying serum levels of cytokines (IL-1β, IL-2, IL-5, IL-10, and IL-17a) by ELISA and assessing behavioral despair using the forced swim test (FST).
Results:
We evaluated how Immunoflu affects the chronic fatigue model at doses of 100, 200, and 400 mg/kg by measuring serum levels of IL-1β, IL-2, IL-5, IL-10, and IL-17a and assessing despair using the “Forced swim test”. In the forced-swimming-induced chronic fatigue model in rats, Immunoflu at a dose of 100 mg/kg increased the serum IL-2 indicator by 23.8%, and Immunal at a dose of 50 mg/kg increased it by 23.3% compared to the model control group, a statistically significant difference (p < 0.05). Furthermore, Immunoflu at 200 mg/kg reduced IL-17a cytokine levels by 23.7% compared with the model control group. When evaluating the swimming state of the animals with the Forced swim test, the group given Immunal 50 mg/kg (52.03±9.3 sec) decreased by 31.6% (*p=0.038), and the group given Immunoflu 100 mg/kg (49.19±8.54 sec) decreased by 35.3% (*p=0.01) respectively compared to the model control group, while no statistically significant difference was observed in other groups.
Conclusions
1. Immunoflu at 100 mg/kg demonstrates immunostimulatory effects in a chronic fatigue model by increasing serum IL-2 levels by 23.8%. Additionally, at 200 mg/kg, it exhibits anti-inflammatory properties, reducing IL-17a levels by 23.7%. 2. In the forced-swimming model, Immunoflu at 100 mg/kg effectively reduced behavioral despair and physical fatigue by 35.3%.

Mongolian Journal of Health Sciences 2026;95(5):141-145
Background:
Onion peel is a raw material rich in biologically active compounds; however, within the framework of food waste management in Mongolia, detailed studies and safety evaluations of this material remain insufficient. Therefore, it is necessary to scientifically determine the properties of onion peel waste generated from the food production sector and explore its potential for reuse.
Aim:
To evaluate the safety parameters of red and white onion (Allium cepa L.) peels generated during food processing and to determine their bioactive compound content and antioxidant activity.
Materials and Methods:
Red and white onion peels were used in this study. Safety parameters were determined using atomic absorption spectrometry (for heavy metals) and GC-MS/MS and LC-MS/MS (for pesticide residues). The raw materials were extracted with 70% ethanol, and dry extracts were obtained using a vacuum evaporator and freeze dryer. Total phenolic content (TPC) and total flavonoid content (TFC) were measured by spectrophotometric methods, while antioxidant activity was evaluated using the DPPH radical scavenging assay.
Results:
The analysis showed that the levels of lead, cadmium, and 205 pesticide residues in onion peels did not exceed the permissible limits, indicating that the material is safe. Phytochemical analysis revealed the presence of quercetin and luteolin derivatives in the dry extracts. The TPC (27.40±1.64%) and TFC (17.95±1.47%) of red onion peel extract were significantly higher than those of white onion peel extract (20.34±0.34% and 12.69±1.44%, respectively). The IC₅₀ values were 17.58 μg·mL⁻¹ for red onion and 19.41 μg·mL⁻¹ for white onion, indicating strong antioxidant activity for natural composite extracts.
Conclusion
Onion peel waste meets safety requirements and exhibits strong antioxidant activity. These findings demonstrate its potential as a valuable raw material for the development of antioxidant preparations and functional food additives aimed at preventing oxidative stress.

Mongolian Journal of Health Sciences 2025;85(1):115-119
Background:
Patients with rheumatoid arthritis are at increased risk of developing cardiovascular disease. In Mongolia,
the registration of inflammatory diseases is increasing every year, and cardiovascular diseases are the leading cause of
death.
Aim:
We aimed to determine the degree of cardiovascular risk and its correlation in people with rheumatoid arthritis.
Materials and Methods:
The study was conducted in a cross-sectional study design with 64 patients with rheumatoid
arthritis between May and November 2024. Cardiovascular risk was assessed using mSCORE and the World Health Organization (WHO) cardiovascular Risk Table. We received ethical approval to begin the research at the MNUMS meeting
on May 17, 2024 (No. 2024/3-05).
Results:
The average age of the participants was 55.2±9.7 years, and the average duration since being diagnosed with RA
was 9.8±8.0 years. Among the participants, 82.8% (n=53) were female, and 17.2% (n=11) were male. The mean WHO
risk index was 10.25±11, while the mean mSCORE risk index was 2.9±4 (p=0.001). There was a significant difference in
mSCORE scores between the 40-55 and 56-65 age groups (p<0.001). In contrast, the mSCORE risk assessment showed
that 15.6% (n=10) had high risk, and 6.3% (n=4) had very high risk. Among the parameters of inflammatory biomarkers,
CRP (OR=0.05, r=0.35, 95% CI 0.9-3.2, p=0.004) has a statistically significant difference and positive correlation, and
HDL-C (OR=2.3, r=-0.25, 95% CI 2.9- 10.0, p<0.0001) was significantly different and negatively correlated.
Conclusion
A total of 64 participants participated in our study, and according to the WHO assessment, 17.2% were at
high or very high risk of developing cardiovascular disease in the next 10 years, and according to the mSCORE, 21.9%
were at high or very high risk of developing cardiovascular disease. Although the degree of disease activity was not significantly associated with cardiovascular risk, the inflammatory biomarker C-reactive protein was statistically significantly different or positively associated with cardiovascular risk assessment.

Mongolian Medical Sciences 2023;205(3):20-26
Background:
Some scholars believe that the study of ancient medical works to gain insight into their scientific
concepts and correctly understand the profound techniques of doctors are very important to the
development of traditional medicine in the 21st century. Cardiovascular disease, the third leading
cause of morbidity in Mongolia's population, was 936 per 10,000 people in 2021, an increase of
128 over the ten-year average and 68 decreased the previous year. According to 2021 statistics,
cardiovascular diseases remain the leading cause of death in the population, with 5000-5500 deaths
per year, or one death in every three people. In 2021, hypertension accounted for 51.6 percent of
cardiovascular diseases, an increase of 7.9 percent from 2012.
Goal:
To analyze the mechanism of action of Marcin-13 on the wind-blood ascending disease and compare
with its effect on the pathological model of hypertension induced by dexamethasone.
Materials and methods:
In our study, we used the book named "Oral Instruction Tantra" as main reference material and for
research methods, we used the checklist method to list relevant information about the pathogenesis
of wind-blood ascending disease and Dmar chen-13 traditional medicine from the literature, so as
to provide preconditions for further analysis. The pathogenesis of wind-blood ascending disease
and the mechanism of action of Dmar chen-13 were analyzed by theoretical analysis methods and
the comparison method was used to contrast the mechanism of action of Dmar chen-13 on the
wind-blood ascending disease and its effect on the pathological model of hypertension induced by
dexamethasone.
Results
The mechanism of action of Dmar chen-13 in the treatment of wind and blood ascending disease is to
transform pathological blood into physiological blood so as to adjust the disorder of wind and blood and
finally achieve the purpose of treatment. We compared the mechanism of action of Dmar chen-13 on
wind and blood ascending disease with its effect on the dexamethasone-induced hypertension model.
Inhibiting the release of renin, angiotensin and aldosterone is equivalent to transforming pathological
blood into physiological blood, opening up blood vessels, and balancing wind and blood disorders in
traditional medicine.

Mongolian Medical Sciences 2022;199(1):53-61
Introduction:
This field assessment was performed to ensure the effective implementation of Order No. A/142 of the Deputy Prime Minister of Mongolia dated 30th December 2021 and Order No. A/01 of the Head of the National Committee for Reducing Environmental Pollution dated 3rd January 2022 and to monitor the level of indoor air pollutants emitted from traditional stoves and standard stoves.
Purpose:
To determine the level of indoor air pollutants emitted from briquette combustion and to develop recommendations by comparing various types of stoves and dwellings.
Materials and Methods:
Through analytical cross-sectional designs, three households from Songinokhairkhan district and one household from Chingeltei district were selected to participate in this assessment as they use briquettes for heating, vary in their dwelling types (ger (traditional Mongolian tent), house) and their stove types (traditional, standard), stay home during the day and chose to participate in the assessment. 24-hour continuous measurements were conducted for each dwelling and before taking measurements, we calibrated and adjusted the air suction velocity of the measuring instrument at the Central Metrology Laboratory. The monitor was placed at a distance of 0.5m from the stove and a height of 0.5-1.0m from the floor. The results were then compared with the Mongolian National Standard “General air quality and technical requirements MNS4585:2016” and WHO Guidelines for Indoor Air Quality 2021. Statistical analysis was performed using SPSS 24.0 software, mean, ANOVA test, and if the p-value is less than 0.05, our results are statistically significant.
Results:
The concentration level of SO2 in houses with “Dul” stoves was within the level specified in the Mongolian standard MNS4585: 2016 and WHO Guidelines for Indoor Air Quality 2021, while 24-hour SO2 concentration in gers and houses with traditional stoves was 1.3-2.92 times higher than the standards. The 24-hour average concentration of nitrogen dioxide in houses with traditional stoves was 1.73 times higher than the Mongolian air quality standard MNS4585: 2016. There were statistically significant differences in the emission levels of SO2 and NO2 depending on dwelling and stove types (df=4, f=4.04, p=0.008 and df=4, f=17.17, p=0.001, respectively.). The 8-hour average (10,000 μg/m3) CO concentration was statistically significant for various types of dwellings and stoves (df=4, f=45.17, p=0.001), whereas there was a statistically significant difference in CO concentrations in gers with traditional stoves and gers with standard stoves in terms of morning, afternoon, and evening hours (df=3, f=33.17, p=0.001).
Conclusion
Indoor air pollutants in the households except for houses with “Dul” stoves have been determined to exceed the air quality standards set by the Mongolian air quality standards and WHO Guidelines for Indoor Air Quality 2021.
