In this published case of a male patient B., 53, has some epidemiological specifics. There is transient ischemic attack (TIA) syndrome, particularly while with clear mind there is sudden temporary paralysis of left leg and arm and loss of ability to speak. Temporary refers here to a period of 2-3 minutes after which everything gets back to normal. The incidence occurred again in two days during the medical treatment.MRA test concluded on the presence of obvious stenosis at the beginning part of both sides of a.cerebri media. The mentioned blood vessel pictures were undefined. Hence selected catheter angiography has been done with a purpose to establish the presence of a full occlusion or clogging stenosis in a.cerebri media and to clarify which specific vessels are being mobilized for the collateral supply. This test established that the a.cerebri media had full occlusion on both sides.A duplex sonography conducted in order to clarify characteristics of the clogging (blocking) process concluded the presence of gradual thickening of and blocking in intima (inner wall) of a. carotis interna. Based on these tests we considered that despite the atherosclerosis symptoms (Ischemia in ECG, 20 years of smoking,being male and aged 53, etc), this case had conditions of gradual (slow progressing) arteriopathy. Thus because of the presence in this case simultaneous arteriopathy process (gradually progressing and causing the blocking) in addition to atherosclerosis syndromes we consider it as a Moya-Moya syndrome. The disease of Moya-Moya is mostly found in children and youth and is a unique arteriopathy considered unrelated with atherosclerosis.

Background: High blood pressure is both a cause and a complication of chronic kidney disease. As complication, high blood pressure may develop early during course of chronic kidney disease and is associated with adverse outcomes, in particular faster loss of kidney function and development of cardiovascular disease. The purpose of this study is early detection of chronic kidney disease in patients with hypertension by defining the prevalence of microalbuminuria.Methods: The study population consisted of 169 subjects with a hypertension. Individuals were considered to have hypertension if the blood pressure measured greater than 140/90 mmHg or if they were taking blood pressure lowering medications. Microalbuminuria was defined as 20 mg/l or greater. Results: We are presenting data on 169 subjects :male 38 (22.5%) female 131 (77.5%), average age 51.6±0.89 At screening, 14.8% of all participants were smokers, 62.1 % engaged in low levels of physical activity, 72.8% - were having tea with salt (table1). Microalbuminuria and renal failure, as GFR<60 ml/ min/1.73 m2, were documented in 34.3% and 16.6% of subjects, respectively. There is positive correlation between MAU and increasing-range of blood pressure (table2). Correlation was found between albuminuria and GFR(r= -0.2 p<0.01) and serum creatinine(r=0.31 p<0.01) the regression result has shown that GFR is associated with MAU and serum creatinine (table 3).Conclusions:1. In 34.3% of patient with hypertension was found nephropathies with MAU2. Microalbuminuria is increased with decline of GFR and raise of systolic blood pressure. GFR decline is with the raise of age and serum. It is important to implement in clinical practice screening of MAU hypertensive patients.3. In 2/3 of all screened subjects was found 1 and more risk factors for CVD.

BackgroundEarly detection of minor strokes and their treatment that aim to prevent from complications into severe strokes is a process of secondary prevention. There is a need to extensively use image diagnostics (CT, MRI) because signs are obscure, at times without focal neurological sign but can have special mental or psychological syndromes. The start of minor stroke studies in Mongolia will enable further deepening of these studies in future and give an impetus to identification of theoreticaland practical aspects together with further improvement of diagnostics, treatment and prevention of minor strokes.GoalTo develop and introduce the diagnostic criteria of ischemic and hemorrhagic minor strokes in accordance to the concepts of minor strokes and to treat minor stokes in order to prevent complications into severe strokes.Materials and MethodCurrently there are no globally accepted diagnostic criteria for minor stroke. We support the 1981 WHO criteria of minor strokes as strokes neurological signs of which disappear in relatively short period of time. There is a general notion that it should mean all light forms of stroke other than severe strokes. In cases of neurological signs of a minor stroke, complete recovery and elimination of the symptoms take up to 3 weeks. Most scholars tend to consider ischemic lacunar strokes (arising from occlusion of arteriole vessels deep in the brain and with size of 0.5-20 mm) as minor strokes. We maintained the concept that characteristic features of these strokes are their limited focal areas and the following neurological symptoms: pure motor, pure sensory, light ataxia, etc. We also duly considered a suggestion (D. German, L. G. Koshchug et al, 2008 ) to define minor hemorrhagic strokes as strokes with diameter less than 2 cm and blood volume less than 5 cm3.We identified 60 patients with minor strokes, involved in monitoring using special research template (with a term of at least 1.5years) and involved in pathogenesis treatment. In the treatment, we maintained a principle of differential diagnosis of ischemic stroke symptoms. Specifically, we differentiated the following: signs related to an atherotromb, cardio-embolic, lacunar, hemodynamic, hemorheologic pathogenesis. To verify the diagnoses, we used MRT and CT image tests. We executed paraclinic tests in order to identify risk factors: Doppler-duplex-sonography, brain angiography, blood lipid fraction, ECG, EchoCG, heart Holter, blood hemorheology test, and identified the most affecting factors (hereditary factors, excess weight, smoking etc).Results: Our study identified the following clinical forms: lacunar stroke, non-lacunar minor stroke, and hemorrhagic minor stroke. Among the minor strokes, the lacunar stroke dominates (48%), the nonlacunar stroke is the next (27.7%), and the hemorrhagic was found to be the least common 25%. From among a host of risk factors, arterial hypertension is dominant (86%) either alone or in combination with such other diseases as diabetes, atherosclerosis etc. Diabetes occurrence was 5 cases (8,3%) which is fewer than in some foreign studies.The clinic of minor stroke also varies. The strength and expression of their symptoms compared with those of severe strokes are unique in the following:- Relatively lighter and recover faster as a result of treatment even in acute forms,- Some are without specific clinical signs (“silent stroke”).- Some minor strokes have micro focal signs, for example, “pure motor”, pure sensory, ataxia etc, in other words, the signs are limited.- In cases of lacunar strokes, predominantly deep brain arterioles are damaged.- Whereas in non-lacun strokes, embolic, ateroma, thrombotic mechanisms are predominant suchas distal branches of big artery. - In cases of hemorrhagic minor strokes, arteriopathy distortions occur not only in depth of brain but also in any small lobar vessels of brain.- Focal lesions have some variations by their pathological locations and minor stroke signs.In non-lacunar strokes (25%), the focal damages predominantly occur in branches of large intra/extra cranial arteries. In cases of lacunars strokes, the focal lesion is not in branches of large intracranial vessels, but is predominantly in basal ganglia, deep white matter, thalamus, pons and in area of deep penetrating arterial vessels. However, focal infarcts in cerebella may occur in any form of minor strokes.ConclusionAccording our study there were identified 3 subtypes of minor stroke. The finding is that lacunars and hemorrhagic minor strokes are more likely to give grounds to severe strokes. From this, it can be concluded that there are specific factors in the population of Mongolia to affect the genesis of minor strokes, namely, arterial hypertension which is directly related with these forms of minor strokes. We appropriate the WHO criteria of minor stroke that is neurological signs of a minor stroke, complete recovery and elimination of the symptoms take up to 3 weeks. In treatment of minor stroke, we suggest that minor strokes should be treating by pathogenetic therapy. Namely, antihypertensive therapy for lacunar infarction, anti-aggregation therapy for nonlacunar infarction and haemostatic and antihypertensive therapy for hemorrhagic minor stroke.

Aim of the study
Aim of the study: The aim of our work intends to define of peripheral analgesic effect of the traditional drug Garidi 5 in experimental animal models.
Objectives of the study:
1. To determinate the LD50 of traditional drug Garidi-5
2. To study of analgesic effect of Garidi-5 on experimental animal models
Material and Methods: Mongolian traditional drug Garidi 5 was produced from the traditional drug manufacture of TMSTPCorporation of Mongolia. - The LD50 of Garidi-5 determined by Chan Chi (2005) - Analgesic effect was assessed by glacial acetic acid-induced writhing test (for peripheral action). All the animals used in the study were taken care of under ethical consideration, with approval from Ethical Committee Corporation and Minister of Health of Mongolia. Analgesia by peripheral action: The peripheral analgesic effect was tested by glacial acetic acid–induced writhing test in Albinomice (Wilkin et al,1961). Healthy mice of either sex weighing 20-30 g were fasted overnight and divided into three groups with six animals in each group. One hour after administration of drugs, induction of writhing was done in mice by giving intra peritoneal injection of acetic acid at a dose of 10 ml/kg body weight. The number of writhing responses were counted and recorded for 20 min. Traditional drug of Garidi 5 (20 mg/kg , 80 mg/kg, 200 mg/kg) was used as the test drug. Aspirin was taken as standard drug at a dose of 100 mg/kg p.o. (Ghosh, 2008)
Results: Traditional drug Garidi-5 is LD50=2,28±0,15, it’s means that drug has low toxicity. Aqueous extract of Garidi 5 had significant peripheral analgesic effect as compared to control (p<0.05).

Background:
Organ transplantation has been rapidly advancing in Mongolia in recent years. The number of successful
kidney, liver, and bone marrow transplants performed in national central hospitals has been increasing annually. While the
number of successful kidney transplants is increasing, post-transplant immune monitoring remains insufficiently studied.
Aim:
To assess post-transplant immune status by analyzing inflammatory cytokine levels in kidney transplant recipients
Materials and Methods:
A prospective cohort study was conducted at the First Central Hospital of Mongolia. Serum
samples from kidney transplant recipients were analyzed using flow cytometry to measure the levels of 13 inflammatory
cytokines, including TGF-β1, PAI-1, sTREM-1, PTX3, sCD40L, sCD25 (IL-2Ra), CXCL12 (SDF-1), sST2, sTNF-RI,
sTNF-RII, sRAGE, CX3CL1 (Fractalkine), and sCD130 (gp130). Statistical analysis was performed to assess the results.
Results:
The mean creatinine level significantly decreased on post-transplant days 7 and 30 compared to pre-transplant
levels (p<0.001, ANOVA). No statistically significant difference was found in the 13 cytokine levels between the high
risk and low-risk groups based on creatinine levels on post-transplant day 30 (p>0.05). However, the levels of TGF-β1,
CX3CL1, sTREM-1, and sTNF-RI showed statistically significant differences between post-transplant days 7 and 30
(p<0.05). No significant correlation was found between the measured cytokine levels and CRP (p > 0.05). On post-transplant day 7, sTREM-1 had a weak correlation with TGF-β1 (r=0.40, p=0.02) and sTNF-RI (r=0.36, p=0.05) but showed a
strong correlation with CX3CL1 (r=0.65, p=0.0001). On post-transplant day 30, sTREM-1 remained strongly correlated
with CX3CL1 (r=0.73, p=0.0001) and moderately correlated with sTNF-RI and TGF-β1 (r=0.45, p=0.01).
Conclusions
1. The levels of TGF-β1, CX3CL1, sTREM-1, and sTNF-RI significantly varied between post-transplant days 7 and
30 (p< 0.05, T-test).
2. On post-transplant day 30, these cytokines were not correlated with CRP but were interrelated among themselves.

Objectives: Aim of this study is to define peripheral analgesic
effect of the traditional drug Garid-5 in mice.
Methods: Garidi-5 produced in drug manufacture of Traditional
Medical Science, Technology and Production Corporation of
Mongolia was used for the study.
All animals used in this study were taken care of under ethical
consideration, with approval from Ethical Committee Corporation
and Minister of Health of Mongolia. LD50 of Garidi-5 was
determined by Chan Chi’s method. Mice of either sex weighing
20-30 g were fasted overnight and divided into three groups with
six animals in each group. One hour after administration of
drugs, induction of writhing was done in mice by giving intra
peritoneal injection of acetic acid at a dose of 10 ml/kg body
weight. The number of writhing responses were counted and
recorded for 20 min. Garid-5 was given to mice at doses of 20
mg/kg, 80 mg/kg, and 200 mg/kg. Aspirin (100 mg/kg) was used
as a standard drug.
Results: The median lethal dose (LD50) of Garid-5 was found to
be 2.28 g/kg. Aqueous extract of Gardi-5 reduced pain from 40.4
% to 47.9% in mice administered acetic acid compare to control
mice (p<0.05).
Conclusion: Garid-5 is safe in mice demonstrating no noticeable
toxicity. Garid-5 exhibits a potent peripheral analgesic effect.

Background:
Obesity, especially central obesity, is a risk factor for non-communicable chronic diseases such as dyslipidemia,
type 2 diabetes mellitus (T2DM), cardiovascular diseases (CVD), and metabolic syndrome (MetS).
Aim:
Study the association between the subcutaneous fat area (SFA) and visceral fat area (VFA) with lipid metabolism
parameters in adults with MetS.
Materials and Methods:
Data from 1511 participants who visited the ‘NURA Mongolia’ Ai Health screening center
between September 2023 and February 2024, including general information, DEXA (Dual X-ray Absorptiometry), and
biochemical analysis results, were used. Metabolic syndrome (MeS) was assessed based on the harmonizing criteria 2009
(≥3 criteria). VFA and SFA were categorized into four groups using quartiles (Q1-Q4). Statistical analysis was performed
using SPSS v26, including T-tests, multiple logistic regression (OR, 95% CI), and ROC (AUC) analysis.
Results:
The average age of the participants was 30.5±3.9 years, with a BMI of 25.1 kg/m², and 49.5% were male. The
group with MetS (n=531) had significantly higher levels of VFA and SFA compared to the group that rated their health as
relatively healthy and had no clinical diagnosis (n=979) (control group) (p<0.0001), with males showing higher VFA and
females showing higher SFA (p<0.0001). The Q4 group for VFA had a significant association with MetS in males (4.611,
95% CI=2.394–9.591) and females (2.253, 95% CI=1.097-3.912) (p<0.001). Logistic regression analysis showed that increased
VFA was more strongly associated with MetS in males (β=0.325, p<0.0001) and females (β=0.338, p<0.003) than
BMI. The AUC for predicting MetS was 0.790 (95% CI=0.750-0.831) for VFA and 0.401 (95% CI=0.351-0.451) for SFA,
with all results being statistically significant (p<0.001). VFA had a higher predictive value compared to other markers.
Conclusion
In healthy men with metabolic syndrome, VFA is more prominently defined, while SFA is higher in healthy
women. Since VFA is a better predictor of metabolic syndrome than SFA, it increases the risk of diseases such as cardiovascular
diseases and type 2 diabetes in men, whereas SFA in women serves as a protective factor.

Background:
Membranous nephropathy (MN) is among the most common causes of nephrotic syndrome in adults. MN
is diagnosed in one third of cases of nephrotic syndrome on kidney biopsy. Kidney biopsy is the gold standard for diagnosing
MN and plays an important role in determining the severity of the disease and in determining treatment decisions
and regimens. Therefore, the lack of research on kidney biopsy in Mongolia is the reason for this study.
Aim:
The aim of this study was to investigate the pathological features in the kidney tissues of patients with primary
membranous nephropathy diagnosed by kidney biopsy.
Materials and Methods:
A retrospective study was conducted on 51 cases of MN diagnosed in kidney biopsies performed
at the First Central Hospital of Mongolia (FCHM) over a period of 12 years. Renal function was calculated using
the CKD-EPI (2021) formula and classified into the stage of CKD by eGFR. Histopathological findings were examined
using 4 light microscopy (LM) stains (Hematoxylin-Eosin, Masson-Trichrome, PAS, and Methenamine silver staining)
and 8 immunofluorescence (IF) microscopy stains (IgG, A, M, complement C3, C4, C1q, and kappa, lambda). The study
excluded secondary MN based on viral markers, tumor markers, and serological tests. Statistical analysis was performed
using SPSS and STATA 15.0 software, using t-tests, Pearson’s chi-square tests, and multiple group comparisons were
performed using ANOVA and Kruskal-Wallis methods. The study design was approved by the Ethics Committee of the
MNUMS, Mongolia. (№ 2023/3-07)
Results:
A total of 305 kidney biopsies performed at the Kidney Center of the FCHM between 2011 and 2023 resulted in
the diagnosis of 51 cases of primary MN. The mean age of patients with membranous nephropathy was 40.6±9.3 years,
with the oldest age of 65 and the youngest of 22 years, and 36 (70.59%) were male and 15 (29.41%) were female. In the
kidney biopsy, the average number of glomeruli was 16.51±7.82 (min-max, 3-54), and by LM, 33.3% showed global
sclerosis of glomeruli by hematoxylin-eosin staining, 94.12% showed thickening of the glomerular basement membrane
(GBM), 31.2% showed double counter staining of subepithelial immune complexes by methenamine-silver staining,
88.24% showed holes in the GBM, and 54.9% showed spike-like changes by Masson-Trichrome staining. IF showed IgG
3+ in 37.3%, 2+ in 39.2%, 1+ in 13.7%, and trace staining in 9.8%, while 74.5% of the cases were positive for C3, 93.1%
for kappa, and 79.5% for lambda. LM showed thickening of the GBM (OR 23.5, 95% CI 0.093-0.53, p value= 0.007)
and interstitial fibrosis (95% CI 6.98-31.07, p value= 0.003) contributing to the decrease in eGFR. The mean time from
the onset of the first symptoms of kidney disease to the time of kidney biopsy was 35.35±61.54 months. Patients who
underwent biopsy later (in months) after the diagnosis of the disease had a higher incidence of interstitial fibrosis (74.6 ±
98.43, 95% CI -90.52-20.68, p value = 0.002).
Conclusion
The histopathological features of MN confirmed by kidney biopsy showed thickening of the GBM in
94.12%, global sclerosis in 33.3%, and holes in 88.2%. Immunofluorescence microscopy showed 100% IgG staining,
while C3, kappa, and lambda were positive in 74.5%, 93.1%, and 79.5%, respectively.
