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.

Background: In traditional medicine, the Shimshin-6 formulation, which consists of Rheum undulatum L., Hippophae rhamnoides L., Zingiber officinalie Roscoe, Saussurea Lappa C.B.Clark, Sal ammoniacum, Tronae veneni, is recommended for women experiencing menstrual retention disorders. In recent years, Shimshin-6 has been widely used to promote postpartum uterine involution for women and our study aimed to evaluate and determine the acute and chronic toxicity effects of Shimshin-6. Aim: To evaluate and substantiate the acute and chronic toxicity effects of Shimshin-6. Materials and Methods: The acute toxicity of Shimshin-6 was evaluated using the rapid method described by V.B. Prozorovsky (1978) by administering intraperitoneal injections of the medicinal extract in white mice to determine the lethal dose. The active dose was determined following the methodology of I.P. Zapadnyuk (1983). Chronic toxicity was evaluated in Wistar rats according to the OECD 407 (2008) guidelines. The test animals were administered Shimshin-6 in tablet form (90 mg/kg and 180 mg/kg) and decoction form (tang) (162 mg/kg) daily for 60 days. At the end of the experiment, biochemical and complete blood analyses were conducted, along with histopathological examination of major organs. The study was conducted with ethical approval granted by the Ethics Committee of the Mongolian National University of Medical Sciences (MNUMS) on October 25, 2024. Results: The LD50 for Shimshin-6 tablets was 4.47 (3.39–5.1) g/kg, indicating low acute toxicity based on the K.K. Sidorov classification. The LD50 for the decoction form was 8.1 (7.1–9.4) g/kg, suggesting it is non-toxic. Regarding chronic toxicity, platelet count was significantly reduced compared to the healthy control group: Shimshin-6 tablet group: 46% reduction at 90 mg/kg and 29.7% reduction at 180 mg/kg. Shimshin-6 decoction group: 60.5% reduction at 162 mg/ kg. Additionally, hemoglobin levels in the decoction group (162 mg/kg) decreased by 15.7% (p<0.05). Biochemical analysis showed a 36.3% reduction in total cholesterol (LDL-C) levels in the tablet group (180 mg/kg) and decoction group (162 mg/kg) compared to the control (p<0.05). Conclusion Shimshin-6 tablets showed low acute toxicity in experimental mice. However, long-term administration may lead to a reduction in platelet count.

Background: Stroke is one of the leading causes of mortality and disability worldwide. Understanding sex differences in risk factors, clinical characteristics and death after stroke might provide valuable evidence for prevention and management of stroke. Aim: We aimed to describe sex differences in risk factors, clinical characteristics and death after intracerebral hemorrhage (ICH) and ischemic stroke (IS) using hospital-based registry in 6 districts of Ulaanbaatar, Mongolia. Materials and methods: We used hospital-based stroke registry in Ulaanbaatar Mongolia. From 2019 to 2020, total of 974 patients with acute ICH and 1612 patients with acute IS were enrolled in this study. The severity of stroke was measured by National Institutes of Health Stroke Scale (NIHSS) and Glasgow Coma Scale (GCS). Risk factors for stroke were defined as patient’s history and their medical record. Death after stroke was registered at 28 days and 90 days by follow-up study. A comparison of categorical and continuous variables was analyzed using chi-squared test, Student’s t-test and Mann Whitney U test. Univariable and multivariable logistic regression analyses were also performed. Results: The mean age of ICH patients was 58.41±11.56. There was significant difference in age (59 vs 57, p=0.009) between women and men. Men with ICH were more likely to drink alcohol (35.4% vs 5.2%, p=0.000) and to smoke (37.0% vs 8.4%, p=0.000) and to have arterial hypertension (72.7% vs 58.6%, p=0.000). However, there were no significant differences in other risk factors including atrial fibrillation, diabetes mellitus, prior stroke and other cardiac diseases. There were no sex differences in clinical characteristics including systole and diastole blood pressure, NIHSS scores and GCS. In our study, case fatality rate was 23.8% at 28 days and 1.9% at 90 days after ICH. By multivariable regression analyses, there were no significant association between sex and death at 28 days and at 90 days (OR:0.74; 95% CI:0.52-1.06, OR: 0.80; 95% CI:0.29-2.21).
The mean age of IS patients was 61.07±12.88. The women were older (63 vs 59, p=0.000) than men. Men with IS also were more likely to be current smokers (37.6% vs 9.0%, p=0.000), current drinkers (33.2% vs 3.4%, p=0.000) and to have arterial hypertension (74.7% vs 65.9%, p=0.000). There were no significant differences in other risk factors. For IS patients, there also was no sex difference in clinical characteristics. Case fatality rate was 13.3% at 28 days and 1.1% at 90 days after IS. By multivariable regression analyses, there were no significant association between sex and death at 28 days and at 90 days (OR:0.90; 95%CI: 0.64-1.26, OR:5.16; 95%CI: 0.99-23.9). Conclusion Our study showed sex differences in some vascular factors of both stroke subtypes which emphasized that we need to implement stroke prevention targeting sex-specific risk factors. While clinical characteristics and early mortality of intracerebral hemorrhage and ischemic stroke were not differed by gender.

Background: The American Heart Association estimates that more than 1 million people die each year from acute coronary heart disease and half a million from acute coronary syndrome, and that $ 115 billion a year is spent on diagnosing and treating coronary heart disease [Word Health Organization, 2013]. Goal: In this study we aimed to using coronary computed tomography angiography (CCTA) to diagnose unstable plaques in coronary artery disease. Material and methods: From 2018 to 2021, we performed a coronary computed tomography angiography (CCTA) scan with a Philips Ingenuity 64-slice computed tomography (64 MD-CT) device and examined 47 patients diagnosed with unstable coronary artery disease at the Reference centre on Diagnostic Imaging named after R.Purev State Laureate, People’s physician and Honorary professor of the State Third Central Hospital.
Common statistical measurements such as means and standard errors were calculated. Probability of results were checked using Student’s test. Result: In studying signs of coronary computed tomography angiography (CCTA) to diagnose unstable plaques in coronary artery disease that coronary artery diameters more widening to compared healthy artery 16(34.0%±6.9), low density sites clarify in plaque (lower than +30HU)- 14(29.8%±6.7), small calcification detect in plaque 36 (74.5%±6.4), ring liked additional density (lower than +130 HU) sees in edge of plaque (Halo sign)-9(19.2%±5.8), plaque edge roughness, erosion liked changes- 18 (38.3%±7.1), rupture of intima (dissection)- 8(17.0%±5.5). Conclusion We detect that computed tomography angiography (CCTA)’s specific signs of unstable plaque of coronary artery disease are coronary artery diameters widening, low density sites clarify in plaque (lower than +30HU), small calcification detect in plaque, ring liked additional density (lower than +130 HU) sees in edge of plaque (Halo sign), plaque edge roughness, erosion liked changes and rupture of intima.

Background: Globally the incidence of stroke is not decreasing, and the deaths and disabilities caused by stroke is increasing every year, especially in low and low-middle income countries.
Long-term trends in stroke incidence in different populations have not been well characterized, largely as a result of the complexities associated with population-based stroke surveillance.
Having reliable data on stroke morbidity and mortality, as well as periodic identification of long-term trends will be important information for proper prevention planning in the population, monitoring the disease and further improving the quality of health care. Material and Method: A prospective cohort study has been conducted in adult citizens (972409 in 2019, 925367 in 2020) of 6 districts of Ulaanbaatar from the 1st of January, 2019 to 31st of December, 2020. All first-ever and recurrent stroke cases were included using special software, developed for stroke registry, based on the WHO STEPS approach from participating radiology departments of state hospitals, district hospitals, and some private hospitals. Information of stroke death was obtained from forensic institute and state registration office of the capital city.
The trends of stroke incidence and mortality was compared to data between 1998-1999 and 2019- 2020 in UB. Results: The age-standardized crude incidence rate per 100.000 person-years of stroke were 209.0/100.000 (n=1934) in 2019 and 194.0/100.000 (n=1821) in 2020 among adults of UB city. The above results were compared to 1998-1999 studies and the incidence rate declined by 94.0/100.000 in 2019-2020, whereas mortality rate increased by 10.0/100.000 in women aged 16-34. Stroke mortality was 11.6% in 1998 and 26.5% in 1999, while in our study it was 33.87% in 2019 and 29.71% in 2020. Although the incidence of stroke rates has decreased in 1998-1999, the mortality rate has not decreased significantly. Conclusion Morbidity and mortality rates among the population of Ulaanbaatar citizen remain highest in the world, compared to 20 years ago with overall morbidity declining but mortality has not decreased.
In recent years, the Government of Mongolia has been focused on reducing non-communicable diseases, but the primary and secondary prevention and control of stroke in the general population, as well as the acquisition of knowledge attitudes, practices and access to health care still need to be improved.

Background: Stroke is still one of the leading causes of morbidity and mortality worldwide. Registry-based data of stroke are scarce in low and middle-income countries such as Mongolia. We aimed to investigate the incidence and mortality of stroke in adult population of UB Mongolia by stroke registration method. Material and Method: Covering 611265 (≥15 years old) adult citizens of three districts of Ulaanbaatar, a population-based prospective study was done from the first, January of 2019 to 31st, December of 2019. All first-ever and recurrent stroke cases were included using special software, developed for stroke registry, based on the WHO STEPS approach from participating radiology departments of state hospitals, district hospitals, and family clinics. Information of stroke death was obtained from forensic institute and state registration office of the capital city. Results : In a 1-year study period, 1068 (women 39.1%) stroke cases were registered in people with 60.16±13.66 years old. Stroke incidence rate was 169.81/100000 including first-ever and recurrent events. Stroke incidence rate was higher in men and people with 80 and above years old. The ratio between IS and ICH was 1.14:1.0. Stroke mortality was 27.1% and mortality rate was 45.94/100000. The highest rate mortality was in ICH subtype, male population and older people. Conclusion We identified relatively high incidence and mortality rate of stroke in ICH indicating an urgent need for improvement of arterial hypertension control, health education and primary prevention mainly among men.
