BackgroundOut of total 209550 cases of cardiovascular diseases in 2011, 66,7% were newly registered cases.Cardiovascular diseases are the number one cause of mortality in Mongolia; an estimated 6291 peopledied from CVDs in 2011, representing 36.7% of all deaths. It shows that CVD mortality level is higherthan in other countries.Materials and MethodsOur survey is a cross sectional study. We have investigated 600 people of the age of 20-40 whowere randomly selected from 6 urban districts of Ulaanbaatar city. With a permission #4 issued bythe Medical Ethics Control Committee of the Ministry of Health on 25th March 2011, our survey wascarried out between the 1st of July 2011 and the 1st of January 2012 based on the Functional DiagnosticLaboratory, Department of Physiology and Pathophysiology, School of Biomedicine, Health SciencesUniversity of Mongolia.ResultsThe CAVI was significantly higher (p<0.001) in 30-40 aged adults (6.68, 95% CI 6.58-6.78) than 20-29 aged adults (6.42, 95% CI 6.32-6.52). Also CAVI has a direct correlation with the cholesterol level(p<0.05, R2=0,011). Serum cholesterol, triglycerides and LDL levels were significantly higher (p<0.05)in men than women. Framingham Heart Score was in the normal range in 99.2% of the participantswith 4 cases having the score of 10% or higher representing a risk score.ConclusionsDislipidemia, overweight and obesity in young adults are the main causes of vascular dysfunctionsleading to cardiovascular diseases. Thus, the findings of the study demonstrate that helping youths todevelop healthy lifestyles including healthy eating and physical activities shall play a critical role for theprevention and intervention programs designed for development of healthy behavior and lifestyle fromchildhood, especially for the male population, are vital for fulfillment of this role.

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.

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.

Background: Data from yearly statistical reports on morbidity and mortality in Mongolia show that young adults account for approximately 20-26% of all stroke patients as opposed to 10-13% in Western countries. Objectives: The aim of this study was to compare characteristics of ischemic stroke between young (20-49 years) and old (50-79 years) patients undergoing investigations and treatment according to one common protocol in a tertiary hospital. Material and Methods: This hospital based prospective study included 110 young and 130 old patients with acute ischemic stroke. Data regarding the etiology of the stroke, diagnostic neuroimaging test results and degree of functional improvement of patients were examined during their observation. Results: The frequency of ischemic stroke at the age of 20-49 years grows from 9.6% to 24.2% and is predominant in the male sex (17.1%), which indicates a young stroke in mongolians is not uncommon. Young adults with ischemic stroke frequently bear both traditional and specific vascular risk factorsthan elderly people (p<0.05). The most common TOAST subtype in the young and old groups was undetermined (26.4% vs.12.3%; p=0.004), other determined cause (22.7% vs. 6.9%; p<0.001), and cardioembolism (20.0% vs. 22.3%) followed by Large-artery atherosclerosis (17.3% vs. 26.2%) and small vessel occlusion (15.6% vs. 33.8%; p<0.001). Partial anterior circulation infarcts were more common among young patients (p<0.001), than in posterior circulation infarcts. Silent brain infarcts and leukoaraiosis are not uncommon brain imaging findings (<0.05) in hypertensive and migraineur patients and should not be overlooked due to their potential prognostic relevance. Outcomes in young adults with hemispheric ischemic stroke can safely be improved with Low- molecular-weight-heparin therapy (OR 1.58; 95% CI, 0.99-2.51; p=0.001).
There were large differences between two groups concerning the 6-month outcome which showed beneficial effect for young stroke patients (mRS:89.1% vs. 66.9%, p=0.002; BI: 84.2% vs.73.1%). Conclusion There are significant differences between young and old patients with ischemic stroke regarding to risk factors, etiological subtypes and improvement of functional deficits associated with the stroke. However, severity of stroke on admittance is similar but six weeks outcome is different among young and old patients with relatively rapid improvement of functional deficit in young stroke patients than old one (mRS: 89.1% vs. 66.9%, p=0.002; BI: 84.2% vs.73.1%).

BACKGROUND: In the recent years, mesenchymal stem cells have become increasingly utilized in regenerative medicine and tissue engineering applications because of their properties for self-renewal, differentiation and immunoregulation. The use of stem cells of various clinical applications is highly expected and the production of good quality stem cells is very critical for basic studies. In the bone marrow, hematopoietic and mesenchymal stem cells from an unique niche in which the oxygen tension is low. Hypoxia may have a role in maintaining stem cell fate, self renewal and multi-potency. We investigated whether low oxygen culture would be beneficial for hematopoietic stem cell and mesenchymalstemcell. MATERIAL: BMCs from 8-12 week aged, 15 mice were subjected to hypoxic conditioning by culture for 8-10 days in 20%, 3%, 1% oxygen. For culture 1x105cell/ml were seeded in colony forming assay and 2x106cell/ml were seeded in L-glutamin mediain chamber slide. We counted cell colonies under different hypoxic condiontins by Olympus IX71 fluorescence microscope. After cell culture in chamber slide, we stained cells by anti-CD90 and anti-CD105 then counted positive cells by Olympus IX71 fluorescence microscope. RESULTS: Compared to normoxic cells and hypoxic cells well morphologically differentiated and counted by Olympus IX71 microscope. More colonies were observed at 3%, 1% oxygen. Statistical significances were identified with granulocytes and macrophage colony (p<0.05) in hypoxic condition. More anti-CD90 and anti-CD105 markers were observed at 3% oxygen condition. Statistical significances were identified in 3% oxygen condition with cell markers(p<0.001). CONCLUSIONS: Our data suggests low physiological oxygen culture could improve the stemness of macrophage and granulocytes colony and improve the differentiation of mesenchymal cells. Long term culturewith additional cell markers will be necessary to confirm whether low physiological oxygen levels also improve genomic stability

Introduction: Rongalite have many names, the trade name for sodium hydroxymethylsulfinate also sodium formaldehydesulfoxylate.

Introduction: Khuumii (throat singing) is a unique form of art derived from the nomadic population of Central Asia, producing two or more “simultaneous” sounds and melodies through the organ of speech. Material and Methods: The aim of the study is to identify the anatomical structures involved in the formation of khuumii and the features and patterns of their functions and compare each type of khuumii as performed by Mongolian people. A total of 60 participants aged 18-60 years (54 men and 6 women) were selected by non-random sampling method using cross-sectional study. Statistical analysis was performed using SPSS 23 software using questionnaires, X-ray, endoscopy, sound research method, and general blood tests. Results: 90.7% of the khuumii singers were male and 9.3% were female. The average height of the participants was 172.91±0.93 cm (arithmetic mean and mean error), average body weight was 77.53±2.46 kg, and body mass index was 25.93±5.31 respectively. Heart rate was 92.19±20.71 per minute prior to khuumii while 133.19±19.09 after performing khuumii and 85.81-98.56 at 95% confidence interval. In terms of ethnicity (ethnographically), the Khalkh were the largest ethnic group (72.1%), followed by Bayad, Buryatia, Darkhad, Torguud, and Oirat (2.3%), respectively. 60.5% of the participants were professional khuumii singers who graduated from relevant universities and colleges. The process of Khuumii was recorded by X-ray examination, and laryngeal endoscopy evaluated the movement of true and false vocal chords, interstitial volume, movements of epiglottis and arytenoid cartilage, and mucosa. Khuumii increases the workload of the cardiovascular system by 70-80%. Furthermore, the sound frequency is 2-4 times higher than that of normal speech, and sound volume is 0.5-1 times higher. 95.3% of throat singers did not have a sore throat, 88.4% did not experience heavy breathing, and 74.1% had no hoarseness. During the formation of khuumii sound, thoracic cavity, diaphragm, and lungs regulate the intensity of the air reaching the vocal folds, exert pressure on the airways and vibrate the sound waves through air flows passing through the larynx and vocal folds. Mouth-nose cavity as well as pharynx are responsible for echoing the sound. Conclusion It is appropriate to divide khuumii into two main types according to structural and functional changes in the organs involved; shakhaa and kharkhiraa. Khuumii, the “Human music” originating from the people of Altai Khangai basin by imitating the sounds of nature with their own voice in ancient times, spread all over the world from Mongolia and it is proposed to classify khuumii into two main types of shakhaa and kharkhiraa in terms of structural involvement and functionality.
