Background: Plants of the genus Achillea are widely used in both traditional and modern medicine and are known to be rich in biologically active secondary metabolites. Numerous phytochemical and histochemical studies have been con ducted on Achillea millefolium L.; however, Achillea asiatica Serg., which is widely distributed in Mongolia, remains comparatively underexplored. Therefore, investigating the distribution of biologically active compounds, the content of polyphenolic compounds, and the optimal extraction conditions of this species is of significant scientific and practical importance. Aim: The aim of this study was to identify biologically active compounds in Achillea asiatica Serg. using histochemical methods, to determine the content of polyphenolic compounds and optimal extraction conditions, and to evaluate the total and internal absorption coefficients of the plant raw material. Materials and Methods: The aerial parts of Achillea asiatica Serg. were collected in August 2025 from Erdene soum, Tuv province, Mongolia. Histochemical analysis was performed on transverse stem sections and flower petals using potassium dichromate, ferric chloride (III), methylene blue, Lugol’s iodine, and Dragendorff’s reagent, followed by ob servation under a light microscope. The total polyphenolic content was determined using the Folin–Ciocalteu method and expressed as gallic acid equivalents. Extraction experiments were conducted using powdered plant material sieved to par ticle sizes of 1, 2, and 3 mm and extracted with 20–80% ethanol. In addition, the total and internal absorption coefficients of the plant material were determined according to standard procedures. Results: Histochemical analysis revealed the presence of essential oils, polyphenolic compounds (tannins and flavo noids), and starch, while alkaloids were not detected. Polyphenolic compounds were observed in both stems and flow ers, with more pronounced accumulation in the vascular tissues. The highest total polyphenolic content (0.421%) was obtained from the 1 mm particle-size fraction extracted with 70–80% ethanol. Using 60% ethanol, the total absorption coefficient of the plant material was determined to be 5.74, and the internal absorption coefficient was 1.885. Conclution Achillea asiatica Serg. is rich in polyphenolic compounds, and their anatomical distribution is closely as sociated with the plant’s protective and biological functions. The use of 1 mm particle-size material and 70–80% ethanol was identified as the most suitable condition for extracting polyphenolic compounds. These findings provide a scientific basis for the standardization of Achillea asiatica Serg. as a medicinal and phytopharmaceutical raw material and support its further pharmacognostic and phytochemical investigation.

Background: In atopic dermatitis, impairment of the skin barrier function leads to increased susceptibility to environ mental particles and pollutants, thereby contributing to disease pathogenesis and complications, as well as to an increased risk of fungal skin infections. In children with atopic dermatitis, infections caused by Candida species exacerbate the dis ease and reduce the effectiveness of treatment. Candida species are common opportunistic pathogens colonizing the skin and mucosal surfaces, and more than 200 species have been described. Among these, Candida albicans, C. glabrata, C. parapsilosis, C. tropicalis, and C. krusei are most frequently isolated from the skin, mucosa, and oral cavity. In Mongolia, studies culturing skin fungi and determining their metabolic activity and virulence factors are limited, which constituted the rationale for the present study. Aim: To determine virulence factors and selected biochemical activities of Candida species. Materials and Methods: In this study, Candida species strains cultured from clinical samples of children with atopic der matitis were used with research approval. The fungal strains preserved at –80°C were revived by culturing on Sabouraud Chloramphenicol Agar and evaluated microscopically after Gram staining. Biofilm-forming activity was determined us ing the microtiter plate method, in which cultures were grown in broth, optical density was measured using a microplate reader, and values were calculated using a standard formula. Phospholipase activity was assessed using egg yolk agar according to the method developed by Price et al. Results: Of the total cultured isolates, 54.1% (n=33) demonstrated weak biofilm-forming activity (≤ODc / ODc < ~ ≤2×ODc), while 32.79% (n=20) showed moderate biofilm-forming activity (2×ODc < ~ ≤4×ODc). Isolates exhibiting strong biofilm-forming activity (>4×ODc) accounted for 13.1% (n =8) Regarding phospholipase activity, 50% of the isolates showed strong activity, 30% showed moderate activity, 10% showed low activity, and 10% exhibited very weak activity. Conclusions 1. Virulent fungal strains capable of attaching to host cells are involved in the pathogenesis of atopic dermatitis. 2. Atopic dermatitis is shown to contain fungal strains that damage host cells and are involved in the process of inva sion.

Background: Skin diseases are highly prevalent worldwide. Although plant-derived medicinal materials continue to be used among Mongolians for the traditional and household management of dermatological conditions, studies that systematically quantify their frequency of use, informant consensus, and cultural significance remain limited. Aim: To determine the traditional knowledge, patterns of use, and cultural significance of plant-derived medicinal materials used for dermatological conditions among residents of Ulaanbaatar using quantitative ethnobotanical indices. Materials and Methods: Information was collected on the diversity of plant species used for dermatological conditions, modes and frequency of use, perceived effectiveness, adverse effects, and methods of preparation and processing. The collected data were evaluated using quantitative ethnobotanical indices, including the Use Value (UV), Relative Frequency of Citation (RFC), Informant Consensus Factor (ICF), Fidelity Level (FL), Relative Popularity Level (RPL), Rank Order Priority (ROP), Cultural Importance Index (CII), Jaccard Index (JI), and Shannon–Wiener Diversity Index (SDI). Statistical analyses were performed using Microsoft Excel 2016. The study was conducted with the approval of the Research Ethics Review Committee of the Mongolian National University of Medical Sciences (Approval Protocol No. 25-06/03-03 and Ethical Opinion Protocol No. 26/03-B02). Result: A total of 73 plant species belonging to 36 families were documented, with species from the Asteraceae, Rosaceae, Apiaceae, and Liliaceae families being predominant. Regarding modes of use, 29.6% of the remedies were prepared as infusions or decoctions and applied as washes or topical applications, 18.9% involved the direct application of plant juice, and 18.1% were applied as mashed plant material or poultices. Aloe barbadensis showed the highest ethnobotanical importance, with UV= 0.19, RFC=0.128, CII=0.19, RPL=1.00, and ROP=100. Nugaraa altan tovch, Gobi thyme, yashilduu sea buckthorn, and greater plantain were also highly ranked. The Informant Consensus Factor was highest for thermal burns (ICF=0.82), followed by open wounds (ICF=0.77) and pustular acne (ICF=0.76). Eighteen species overlapped with the 126 medicinal materials recorded in traditional medicinal prescriptions, yielding a Jaccard Index of JI=10%. The Shannon–Wiener diversity index was H′=3.4184, with an evenness value of E=0.7967. Among the informants, 40.8% reported a reduction in symptoms, while 61.9% reported no adverse effects associated with the use of plant-derived medicinal materials. Conclusion 1. Among residents of Ulaanbaatar, information was documented on the use of 73 plant species belonging to 36 families for skin diseases. Knowledge of these plants was transmitted mainly within families, and topical methods of use, including washing with herbal infusions, rinsing, and direct application of expressed plant juice, were predominant. 2. According to the quantitative ethnobotanical indices, Aloe vera showed the highest values for use, citation frequency, and cultural importance. Matricaria chamomilla L., Thymus gobicus Tschern., Hippophae rhamnoides L., and Plantago major L. also ranked highly. The highest Informant Consensus Factor (ICF) values were observed for thermal burns, open skin wounds, and acne vulgaris.

Background: Lish-6 has been used for treatment pharyngitis, flu and throat disease. Lish-6 is composed from Eugenia caryophylla. Thumb, Saussurea lappa C.B. Clark, Schizostachoum chinense. Rendle, Glycyrrhiza uralensis. Fisch, Gentiana algida Pall, Terminalia chebula. Retz. Anti-fever properties of these plants and their bio-active compounds have extensively been studied. Aim: To determine the anti-fever effects of Lish-6. Marerials and Methods: Fever was induced by intravenous administration of lipopolysaccharide (LPS) at concentration of 0.5 mg/kg. Lish-6 was given orally at concentration of 92 mg/kg, 1 and 6 hours after the LPS administration. Rectal temperature wa measured 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 hours after the LPS administration. Paracetamoli was given orally at concentration of 50 mg/kg. Blood levels of Prostaglandin E2 (PGE2) and interleukin-6 (IL-6) interleukin-1β (IL-1β) were determined by enzyme linked immune sorbent assay using rat kits. Lung tissue was examined by histopathological analysis. Results: The body temperature of rats in the normal group was 35.0±1.10С, while in the control group, periodic fever was caused by the effect of lipopolysaccharide (p=0.001). But in the Lish-6 drug group, rectal temperature decreased steadily (p=0.05). In addition, the IL-1β cytokine in the normal group was 3.24±0.31 ng/L and increased by 60.5% in the control, indicating the development of the pathological model, while this parameter decreased by 31% in the Lish-6 drug group (p=0.05). IL-6 cytokine in the normal animals was 21.1±0.2 pg/L and increased by 19.04% in the control, indicating the development of the pathological model, while this parameter decreased by 8.3% in the Lish-6 drug group (p =0.05). PGE2 in the normal group was 43.2±0.3 ng/L, and it increased by 62.7% in the control group, indicating the development of a pathological model, while this parameter decreased by 53.3% in the Lish-6 drug group (p=0.05). Conclusion Lish-6 traditional drug has the effect of reducing rectal temperature, IL-1β, PGE2 and IL-6 cytokines during lipopolysaccharide-induced febrile pathology model.

Background: Lish-6 has been used for treatment pharyngitis, flu and throat disease. Lish-6 is composed from Eugenia caryophylla Thumb, Saussurea lappa C.B.Clark, Schizostachoum chinense Rendle, Glycyrrhiza uralensis Fisch, Gentiana algida Pall, Terminalia chebula Retz. Anti-fever properties of these plants and their bio-active compounds have extensively been studied. Aim: To determine the pain relief and antibacterial effects of Lish-6. Materials and Methods: To conduct acute toxicity study using V.B. Prozorovsk method. Average lethal dose, lethal and maximum nonlethal doses were determined. Acetic acid (1%-0.1 ml) was injected into the rat abdominal cavity to induce pain. Wistar rat of either sex (n = 6) weighing 18–22g were used. All animals were withdrawn from food 2h before the start of experiment and were divided in five groups. Group I was injected with normal saline (10ml/kg) as control, Diclodenk was given orally at concentration of 25 mg/kg. Group II III, IV, V and VI were injected with Lish-6 was given orally at concentrations of 9.2, 18, 36, 92, 184 mg/kg injection of acetic acid. The number of abdominal constrictions (writhes) were counted of acetic acid injection for the period of 20 min. To determine the antibacterial effect by dilution method. Results: Average lethal dose of Lish-6 was found to be LD50=0.92 (0.6-1.04) g/kg suggesting that it is slightly toxic animals. Control group animals abdominal constrictions 72.4±8.8. Lish-6 concentrations of 9.2, 18, 36, 92, 184 mg/kg group animal reduced acitic acid induced pain by 41.9-78.7% suggesting that it is pain relief effect (p<0.001). 4 g of Lish-6 medicine is active against gram-positive bacteria (S.aureus, Streptococcus pneumonia). However, it is inactive against gram-negative bacteria. In other words, Lish-6 medicine inhibits the growth of methicillin-resistant and non-resistant S.aureus bacteria at a dose of 500 mg. It was also found to inhibit Streptococcus pneumonia at a dose of 250 mg. Conclusion Average lethal dose of Lish-6 was found to be LD50=0.92 (0.6-1.04) g/kg suggesting that it is slightly toxic animal. Lish-6 reduced acitic acid induced pain by 41.9-78.7% suggesting that it is pain relief effect. Lish-6 traditional drug has an antibacterial effect.

Introduction: An international study coordinated by the International Agency for Research on Cancer (IARC) and published today in The Lancet Oncology shows that in 2001–2010, childhood cancer was 13% more common than in the 1980s, reaching an annual incidence rate of 140 per million children aged 0–14 years worldwide. Cancer incidence and mortality statistics reported by International Cancer Research Center (2016), over 300,000 children develop cancer worldwide each year, 215000 children aged 0-14 years and 85000 children aged 15-19 years. Internationally comparable data on childhood cancer incidence in the past two decades are scarce. Based on the need for comparison of childhood cancer incidence in Mongolia to the global level, the study aimed to categorize cancer among children aged 0-19 years. Goal: To study the insidence rates and trend from childhood cancer last 10 year in Mongolia Materials and Methods: The study was conducted in 786 new cases childhood who were cancer diagnosed, between 2008 and 2017 year. Age-standardized incidence rates were calculated by the direct method using age-specific incidence rates and weights based on the age distribution of the standard world population Results: Over the past 10 years, childhood cancer accounted for 1.5% of total cancer in Mongolia. By WHO and IARC data, worldwide childhood cancer age standardized rate (ASR) is 106.0, in Mongolia childhood cancer ASR (101.6) is lower than world average. The most common childhood cancers worldwide are: 1st leukemia, 2nd lymphoma, 3rd central nervous system cancer, 4th retinoblastoma, 5th soft tissue cancer. Over the past 10 years the most common childhood cancers in Mongolia are: 1st leukemia, 2nd central nervous system cancer, 3rd joint bone cancer, 4th lymphoma, 5th soft tissue cancer. Our country’s childhood cancer ASR is below compared to other countries, but expected growth rate is gradually increasing (3.0 per year). Conclusions
1. Leukemia is the most common childhood cancer in worldwide and also in Mongolia.
2. By sex, childhood cancer incidence is higher in boys than girls.
3. By age group, childhood cancer incidence is the highest in 0-4 age group.
4. By region, childhood cancer incidence is the highest in central region.
5. The overall incidence of childhood cancer (1 million children) in Mongolia is expected to increase by 3.0 over the next 5 years.

National cancer center of Mongolia has responsibility to produce National cancer registry annual reportwhich is collected cancer reports from primary, secondary and tertiary level of government hospitals andprivate hospitals, laboratories. MCR and indicators of incidence and mortality are important for planningand evaluation of all levels for cancer control, primary prevention, diagnosis, treatment, rehabilitation.ObjectiveThe aim of this study was to determine ASR and ASMRs of cancer incidence and deaths in Mongoliafrom 2008 to 2012 for comparing the results of data.Material and MethodsData on new cancer cases diagnosed in 2008-2012 in permanent residents of Mongolia, collected bycancer registry of the National Cancer Center, were used for the analysis. Incidence and mortality rateswere calculated as mean annual numbers per 100,000 residents. ASRs (Age-standardized incidencerate) and ASMRs (Age-standardized mortality rates) were calculated by the direct method from agespecificincidence and mortality rates, weighted to the World Population standard.ResultsFirst five most frequent cancers (liver, stomach, lung, esophagus, cervix uteri) comprise 76% of all newcancer cases.In males, the most frequent cancer site was liver, followed by stomach, lung, esophageal, colon andrectal cancer. In females, liver is in the first place, followed by stomach, cervical, lung, esophagealcancer.Mean annual crude incidence rate of all cancer sites was 155 per 100 000 population,in males 165, infamale 165 in 2008-2012 years.During this period, mean annual age-standardized incidence rate of all cancer sites was 218,3 per 100000 population, for male 258.9 in female 188.1with higher percentage of men.As we age, morbidity of the cancer increases approximately 2 fold in both sexes and also study revealsmen has more tendency to have cancer than women

Stigmatization and discrimination against mental patients and their family members due to typical community misunderstanding about mental diseases are commonly occurred among population. Particularly, discrimination against alcoholic patients and stigmatization against theirfamily members are most common among Mongolian people, because prevalence of alcohol dependence problems is increased 2 times more in last decades. Our aim was to define current situation of stigmatization and discrimination against alcoholic patients. This survey has been conducted among total 90 inpatients with alcoholic problem, are have staying in National Center for Mental Health and Narcology Center. We conducted the study by descriptive and crossectional design.Totally 90 alcohol patients, aged 19-61 years were participated in our survey. 67 (74.4%) of them were male and 23(25.5%) were female and average age was 40.1±1.1. Level of job’s discriminationwas growingrelated to increasing the level of alcohol consumption (p<0.0016)and level of family’s stigma was growing related to increasing the level of alcohol dependence (p<0.0001). Most of patients (n=29), who are divorced from their couples were answering that main reason of their divorcing was alcohol problem and bad interfamily relationship.Furthermore, stigmatization and discrimination increasing due to increasing level of alcohol consumption (p<0.0001).Most of participants (60%; n=54) are answered, that stigma and discrimination against them were occurring from their family.
