Postmenopausal estrogen deficiency can lead to genitourinary syndrome of menopause (GSM), which manifests as vaginal dryness, dyspareunia, and sexual dysfunction, among other clinical symptoms. These complications often result in emotional distress and a decline in overall quality of life (7). Several studies estimate that 25–50% of postmenopausal women experience symptoms such as pain during intercourse, burning, itching, and dysuria due to vaginal atrophy and inflammation (9). Menopause is commonly diagnosed based on the absence of menstruation and hormone levels (10), but one of the simplest diagnostic methods is the evaluation of the vaginal microenvironment. There is limited data in Mongolia regarding the vaginal microenvironment of perimenopausal and postmenopausal women and the factors influencing its changes. This gap in knowledge formed the basis of our study. The aim of this research was to assess the vaginal microenvironment in menopausal women and to analyze its relationship with various influencing factors. We conducted a cross-sectional observational study using a descriptive research design. A total of 110 women aged 45–55 years, presenting with menopausal symptoms at “Santmaral” Women’s Clinic and the Women’s Outpatient Department of Songinokhairkhan Health Center, were selected for the study. Both quantitative and qualitative research methods were employed, including surveys and physical examinations. Participants completed a 10-minute questionnaire consisting of 8 open-ended and 12 closed-ended questions. The vaginal microenvironment was assessed using special pH test strips applied to vaginal secretions. Data were analyzed using Excel 21 and SPSS 23, comparing the vaginal microenvironment with various influencing factors. The results showed that the average vaginal microenvironment pH among menopausal women was 5.18 ± 0.45 (n=110). In married women, the average pH was 5.1 ± 0.45; among women with a history of pregnancy, it was 4.10 ± 1.58; and among those who had given birth, it was 2.8 ± 0.98 — indicating an abnormal vaginal microenvironment. Women who were using hormone replacement therapy had an average pH of 5.05 ± 0.45, while those using non-hormonal contraceptive methods had an average pH of 5.3 ± 0.43. These findings were statistically significant (p = 0.0001****)

Background: The COVID-19 pandemic has profoundly impacted global mental health, exacerbating anxiety, depression, and insomnia, with prevalence rates of 25–30%, 27–32%, and 30–45%, respectively—2–3 times higher than pre-pandemic levels. Neuroticism, a key personality trait from the Big Five model, characterized by heightened negative emotions and stress reactivity, has been linked to increased vulnerability. Meta-analyses show neuroticism triples anxiety risk (OR=3.21; 95% CI: 2.35–4.39) and correlates strongly with insomnia (r=0.46, p<0.001) and depression during the pandemic. In Mongolia, empirical data on neuroticism's role remains limited. Objective: This study examines whether neuroticism acts as a risk factor for anxiety, depression, and insomnia among hospitalized patients during COVID-19. Methods: A cross-sectional descriptive study enrolled 552 patients (72.3% COVID-19 cases, 27.7% controls) from tertiary hospitals in Mongolia (2024). Participants (mean age 52.8±15.5 years; 60.5% female) completed self-reported questionnaires: Eysenck Personality Inventory (EPI) for neuroticism, PHQ-9 for depression, GAD 7 for anxiety, ISI for insomnia, and PCL 5 for PTSD. Sociodemographics were assessed. Data were analyzed using SPSS 26.0 with chi-square tests (p<0.05 significance). Instruments showed high reliability (Cronbach’s α=0.81–0.89). Ethical approval was obtained from MNUMS Ethics Committee (No. 2024-Psy-17). Results: Overall, 79.5% were depression free, 84.8% anxiety-free, and 77.5% insomnia-free. High neuroticism (n=381) was significantly associated with depression (24.4% vs. 11.7%, p<0.001), anxiety (18.6% vs. 7.6%, p<0.001), insomnia (28.3% vs. 9.4%, p<0.001), and any mental disorder (21.3% vs. 7%, p<0.001), but not PTSD (p=0.472). Cholerics (n=200) showed elevated risks (depression 29.5%, insomnia 34.5%, p<0.001), while sanguines/phlegmatics were protective. Verbal expression and trust levels showed no significant associations. Conclusion Neuroticism significantly heightens risks for anxiety, depression, and insomnia during COVID-19, underscoring the need for targeted psychological interventions. Temperament-informed screening could enhance prevention strategies in crisis settings.

Background: Saponins are secondary metabolites in plants that play an important role in defense mechanisms and physiological processes. Since stomatal cells are crucial for gas exchange and water balance in plant tissues, studying the anatomical and biochemical features of stomatal cells in saponin-rich plant species provides insight into the interactions between these compounds and cellular mechanisms. This serves as the basis of our study. Aim: To determine the structure, types, and functions of stomatal cells in saponin-containing medicinal plants Materials and Methods: During June–September 2024, nine species of saponin-containing medicinal plants were collected from Bulgan, Tuv provinces, and “Gorkhi-Terelj National Park” in Mongolia. Prepared microscopic specimens were examined using macroscopic and microscopic techniques to study the structure, position, number, and epidermal features of stomatal cells. Results: The study revealed that Anemone crinita Juz. exhibited the highest stomatal density (107 stomata/mm²) and epidermal cell density (229 cells/mm²), indicating strong adaptation and protective capacity in arid conditions. Vicia baicalensis (Turcz.) B. Fedtsch. showed the highest stomatal index (39.6), highlighting its significant role in regulating transpiration. Stomatal types varied among species: • Anomocytic stomata were observed in Potentilla multifida and Vicia baicalensis. • Anisocytic stomata were found in Delphinium grandiflorum and Ranunculus borealis. • Paracytic stomata were present in Gentiana algida, Adenophora remotiflora, Helianthemum nummularium, Anemone crinita, and Ranunculus acris. Conclution In the study of the structure, form, and number of stomatal cells in saponin-containing plants growing in Mongolia, Anemone crinita Juz. was found to have the highest number of stomatal and epidermal cells, indicating its high efficiency in gas exchange, water regulation, and protection against external stress. Furthermore, Vicia baicalensis (Turcz.) B.Fedtsch. showed the highest stomatal index, confirming its strong capacity for active regulation of gas exchange. The variation in stomatal cell types among plant species was identified as playing an important role in ecological and biological adaptation as well as protective mechanisms.

Background: Plants of the family Gentianaceae in Mongolia are rich in bitter iridoid glycosides, flavonoids, and polyphenolic compounds, and have been traditionally used in Mongolian medicine to promote digestion, protect the liver, and reduce fever. However, standardized information on the micro-morphology and histochemical characteristics of the widely distributed species Gentiana decumbens L.f. is scarce, limiting the assessment of its quality as a medicinal raw material. Aim: To identify the morphological and anatomical characteristics of the aerial and underground parts of Gentiana decumbens and to localize the distribution of starch, polysaccharides, and phenolic compounds using histochemical methods. Materials and Methods: Plant materials were collected in July 2024 from Tsagaan-Uul soum, Khuvsgul province, andshade-dried. Samples were softened in a water–ethanol–glycerol solution (1:1:1) for 24 hours, and transverse and longitudinal sections of stem, leaf, root, and floral parts (anther, petal, receptacle/bract) were prepared using a hand microtome. Sections were cleared with 10% chloral hydrate. Histochemical reagents included potassium dichromate (K2Cr2O7), ferric chloride (FeCl3), Lugol’s iodine (I₂+KI), thymol + concentrated H₂SO₄, and methylene blue. Slides were mounted in glycerin and examined under an Olympus light microscope at 40× and 100× magnifications, and images were recorded using a 12 MP digital camera. Results: Leaf: The leaf exhibits a dorsiventral structure with a dense palisade parenchyma on the adaxial side and a loosely arranged spongy mesophyll on the abaxial side. Stomata are hypostomatic, and collenchyma is well developed around the vascular bundles. Histochemical reactions were negative for starch and phenolic compounds. Stem: The stem consists of an epidermis, a wide cortex, a continuous ring of sclerenchyma, 12–15 collateral vascular bundles, and a broad central parenchyma. Histochemical tests showed a brownish-yellow coloration with potassium dichromate (K2Cr2O7), indicating the presence of polyphenols and lignin, and a brown coloration with Lugol’s iodine, confirming the presence of starch. Reactions with ferric chloride (FeCl₃), methylene blue, and thymol + H2SO4 were mostly negative in cross sections. However, in longitudinal sections, Lugol’s and thymol + H2SO4 showed positive reactions, suggesting the presence of starch and polysaccharides, respectively. Root: The root displays a primary structure with radial xylem and phloem, a distinct endodermis with Casparian strips, and a pericycle layer. Positive reactions were observed with K2Cr2O7 and FeCl₃, indicating phenolic compounds and lignin. Lugol’s iodine showed abundant starch granules in parenchyma cells. Receptacle / Bract: The receptacle is covered by a thick cuticular epidermis with trichomes, and composed of outer and central parenchyma layers containing numerous small closed (amphivasal-type) vascular bundles. Positive reactions were detected with K2Cr2O7 and FeCl₃, indicating polyphenols, flavonoids, and tannins; Lugol’s iodine confirmed the presence of starch; thymol + H2SO4 showed partial positivity for polysaccharides. Stamen (longitudinal section): The stamen structure includes epidermis, endothecium, pollen sacs, and a distinct vascular bundle. Positive staining was observed with K2Cr2O7, Lugol’s iodine, and FeCl3, confirming the presence of polyphenolic compounds, lignified elements, and starch. Conclusion The anatomical features of G. decumbens indicate adaptations to dry, high-light environments through well-developed mechanical strengthening (sclerenchymatous ring), efficient photosynthetic structure (compact palisade mesophyll), and nutrient storage (starch-rich pith and cortex). Histochemical analysis revealed the localization of polyphenolic compounds and starch/polysaccharides mainly in the root, stem, and floral organs, while absent in the leaves, demonstrating organ-specific accumulation patterns. These findings scientifically support the plant’s traditional medicinal uses for digestive stimulation and hepatoprotection.

Background: Serum natriuretic peptide (NT-proBNP) is a critical biomarker for diagnosing left ventricular dysfunction. Heart failure is the leading cause of mortality in chronic kidney disease (CKD), emphasizing the need for its early detection and prognosis. Objective: This study aimed to determine the serum NT-proBNP levels in participants with CKD and establish a cut-off value for predicting heart failure. Methods: A descriptive cross-sectional study was conducted from April 1 to July 1,2024. This study received approval from the Ethics Committee of the Institute of Medical Sciences (Approval No.24/01). A total of 117 CKD patients hospitalized in the Nephrology and Endocrinology Department of the third state hospital were enrolled based on predefined inclusion and exclusion criteria. Data were collected using questionnaires, laboratory and heart ultrasound test results. Serum NT-proBNP levels were measured using a rapid immunofluorescence quantitative analyzer. Data were analyzed with SPSS 26.0. Results: The mean age of the 117 participants was 57.9 ± 14.7 years, with 51.3% being male. The mean serum NT-proBNP level was 7686 ± 12149 pg/mL. Statistically significant differences were observed in serum creatinine, sodium, calcium, CKD stage, and arterial hypertension between genders (p<0.05). NT-proBNP levels in hemodialysis patients differed significantly between heart failure and non-heart failure groups (p<0.05). Significant differences were also found in hemoglobin, serum albumin, NT-proBNP levels, and CKD stages (p<0.05). NT-proBNP correlated significantly with risk factors such as hemodialysis, diabetes, and decreased systolic blood pressure (p<0.0001). A weak inverse relationship was noted between systolic blood pressure and NT-proBNP (R² = 0.16). The NT-proBNP cut-off value for predicting heart failure was 3027 pg/mL, with an AUC of 61.7% (sensitivity: 74.5%, specificity: 55%). Conclusion Serum NT-proBNP levels are elevated in CKD patients regardless of heart failure. The established cut-off value for NT-proBNP in CKD patients to detect heart failure was 3027 pg/mL, with moderate diagnostic utility (AUC = 61.7%).

BACKGROUND: According to International osteoporosis foundation report, osteoporosis is a multifactorial condition associated with an increased risk of fracture and is caused by social, behavioral and physiological factors. Overall incidence is increasing in every country due to people’s life style changes, diet and increased life expectancy. OBJECTIVES: To evaluate the some hormonal effects in bone mineral density among Mongolian population. METHODS: Bone density was measured in the distal one third of radius using the Sunlight Omnisense (Sunlight Medical, Rehovot, Israel) and classified into 3 groups according to WHO osteoporosis criteria. Normal participants were selected into control group and osteoporotic participants were selected into control group. We have evaluated PTH, calcitonin, 25-hydroxy vitamin D in case-control group. RESULT: The prevalence of osteoporosis was 25.7% and 25.3% of participants were osteopenic. It was clear that PTH elevated group (>30.3pg/ml) had more risk of osteoporosis. CONCLUSION: The prevalence of osteoporosis was 25.7% and 25.3% of participants were osteopenic. PTH elevation is risk factor in men.

Introduction: We began treatment of multi drug resistant tuberculosis first from 2003. At that time there was a 1960 cases and most of the cases were from Ulaanbaatar, Darkhan, Selenge, Tuv, Dornod provinces. From all the cases only 62% or 1058 cases were included in treatment. From that 336 patient or 19% deceased, 296 patient or 18% didn’t get a treatment. We did this study because there were never done any research or study of surgical treatment of multi drug resistant tuberculosis in Mongolia. Materials and Methods: We studied cases of patients who undergone lobectomy, since 2007. There were 48 cases of 46 patients, 2 patients surgery were done on both sides. Respondents aged between 14- 45, 25 male (52%), 23 female (48%), all patients got a first - line anti-tuberculosis treatment, such as cat-1, cat-1+cat-2 and 10 variants of these drugs. It was done based on sputum culture test results of NCCD TB surveillance and research department’s laboratory. Results: From the all patients only 77.08% had undergone surgery within the first 3 years. 92% patients were diagnosed with multi drug resistance TB only with the sputum and sputum culture test results, and the rest of the patients were diagnosed using a tissue analyses on the above tests. It was revealed that HR resistant -91.66%, HR+(Z,E,S) -3 drugs resistant -18.78%, HR+(ZSE)-4 or 5 drugs resistant. In the patients TB lesion locations was on the right upper lobe 54%, left upper lobe 31%, on a both upper lobes 85%, cavernous fibrosis tubercles 60%, combined TB lesions 77%, tubercles 21%.87.5% of total patients received a multi - drug resistant TB treatment between 7 - 24 months prior surgery. All 48 patients had a totally 69 surgeries. Surgeries included 9% pneumonectomy, 28% lobectomy, 30% Wedge resection, 23% pleurectomy decortication, 7% Wedge resection on both sides, one bilobectomy. There were no complications during the surgery but 5 of patients had an empyema after surgery. No fatal cases.Three patients out of 5 who had a surgery due to pulmonary hemorrhage developed an empyema after surgery. Drainage tubes were taken after the surgery within 2-3 months.Therewere no complication and escalations in the patients who received a surgical treatment, after the surgery from 6 months to 5 years. Conclusion: In study it shows that surgical treatment is effective to do after 6 months of anti-tuberculosis drug treatment in multi -drug resistant TB patients.Also it shows that combining of medical and surgical treatment is healing up to 98% in the patients who were rightly chosen according to surgical indications.This research result shows that in our country multi - drug resistant TB surgical treatment complication is only 10.41%, which is below in the other countries who have same anti-tuberculosis drug treatment.

Introduction. Garidi-5, a traditional medicine composed of 5 herbs including Terminalia chebula Retz., Aconitum Kusnezoffii Reichb., Acorus calamus L., Saussurea lappa L., and musk of Moschus moschiferus, has been used in traditional Mongolian medicine as an analgesic and antibacterial medicine. The present work was undertaken to evaluate the traditional drug Garidi-5 for its analgesic and anti-inflammatory activity.Materials and Methods. The method of Winter et al. was used to study acute inflammation. Rats in groups of five each were treated with vehicle, Garidi-5 (20, 80 and 200 mg/kg, p.o.) and Indometacin (10 mg/kg) one hour prior to Carrageenan injection. 0.1 ml of 1% Carrageenan was injected into the subplantar tissue of left hind paw of each rat. Swelling of carrageenan injected foot was measured at 0, 0.5, 2, 4 h using Plethysmometer (UGO Basile, Italy)). The right hind paw was injected with 0.1 ml of vehicle.Results. The Garidi-5 (20, 80 and 200 mg/kg) significantly (P<0.01) inhibited carrageenan induced rat paw edema as compared to control group. Maximum inhibition of paw edema was observed with Garidi- 5 (80 and 200 mg/kg) at 4 h when compared to the control group (Tab.1). In assay data, the TNF-α, IL-1β and IL-6 secretion in serum were highly elevated by carrageenan induction but administration of Garidi-5 signifi cantly reduced serum secretion of inflammatory mediatorsas compared to vehicle group (Tab. 2).Conclusion. In conclusion, Traditional drug Garidi-5 have anti-in flammatory properties. The potential efficacy of Garidi-5 to treat inflammation is based in a part on the hy pothesis that it will suppress the proinflammatory cytok ines resulting in less oedema.
