Background. Prevalence of essential arterial hypertension is 60-80% among cardiovascular diseases and WHO reported that prevalence of essential arterial hypertension was 90-95% of arterial hypertension and 80% of hospitalized arterial hypertension patients. One of risk factors of essential arterial hypertension is (lack) deficiency of physical activity. Therefore we studied a benefit of exercise in essential arterial hypertension therapy. Methods. We examined blood lipid level and some of cardiovascular indicators of essential arterial hypertension patients such as arterial pressure, heart rate before and after treatment of exercise. Results. Prevalence of essential arterial hypertension was higher in the patients with obesity and overweight. Right high and low blood pressures were decreased from 154 to 141 and from 93 to 85, respectively. The other hand left high and low blood pressures were decreased from 154 to 138 and from 94 to 86, respectively. Heart rate was decreased from 76 to 71.9. Conclusions. Arterial pressure, heart rate and lipid level of the patients with essential arterial hypertension were significantly decreased after treated by exercise.

Background: Cognitive impairment (CI) is common in Parkinson’s disease (PD) and 20%-80% of patients with PD will develop dementia over time. The Montreal cognitive assessment (MoCA) is a short cognitive screening tool for CI in PD patients. The mini-mental state examination (MMSE) often fails to detect early cognitive decline.Objective: The aim of this study is to compare MMSE to MoCA scores in Mongolian patients with Parkinson’s disease.Methods: Clinical history of 47 patients with diagnosis of PD in according to clinical criteria of the UKBBPD has been enrolled. The patients were assessed using Hoehn and Yahr stage (HY), Unified Parkinson’s Disease Rating Scale (UPDRS III parts), MMSE and MoCA. Patients normal and with CI were classified using cut-off MMSE and MoCA scores 25 or below.Results: Total 47 patients: 21 male (44.7%) and 26 female (55.3%) patients were included. The mean age was 64.2±2.6 years, the mean HY stage was 2.4±0.3 and the mean disease duration was 5.5±1.2 years. The mean MoCA score was 25.7±3.1 (SD 4.3; range 13-30) with the following distribution for categories: normal in 42.6% (20 cases) and CI in 57.4% (27 cases) of patients and the mean MMSE score was 27.2±0.8 (SD 2,8; range 18-30) with the following distribution for categories: normal in 72,3% (34 cases) and CI in 27,6% (13 cases) of patients with PD. Patients with cognitive impairment had advanced HY stage (p<0.05) and greater motor deficiency on UPDRS III (p<0.05) than patients without cognitive impairment. In contrast, there were no significant differences in age, disease duration and onset of disease. Cognitive impairments on the MoCA were seen in numerous cognitive domains, including visuospatialand executive abilities (40.4%), attention (57.4%), abstraction (53.1%), memory (93.6%) and language (68.0%), naming and orientation (8.5%) and on the MMSE were seen in some cognitive domains, including attention (36%), memory (57%) and language (23%) and orientation (19%) respectively.Conclusion:• 57.4% and 27,6% of the patients with PD have cognitive deficits based on their MoCA and MMSE score. This suggests that the MoCA will be more sensitive than the MMSE to detect cognitive impairment in PD patients.• Cognitive impairment was more common in PD patients with advanced HY stage and severe motor symptoms.• Attention, language and memory impairment, executive function and language were the most common patterns of CI in PD patients valued by the using of the MoCA and MMSE.

Backgroundв Previous the prevalence of myotonic dystrophy was identified very rare, because of the poor diagnostics. In fact, due to getting high quality of diagnostical equipments the disease is determined very common among people in the world. According to some researchers’s statistical data during 1980-1990 years, the prevalence was 1.1 in England, 2.4 in South Ireland, 5.0 in Switzerland per 100.000 population.Goal. The study was aimed to establish the prevalence of myotonic dystrophy in MongoliaMethod. In this study which is a part of a general epidemiological study of some hereditary neurological diseases in Mongolia since 1997, authors established the prevalence of myotonic dystrophy among 1.7 million population from 14 aimags and the capital city Ulaanbaatar during the period from 1997 to 2010.Results. The prevalence by aimags was ranged from 0.0 to 27.06 per 100.000 population. The average nationwide prevalence is 5.63 per 100.000. Several aimags, especially Gobi-Altai, Orkhon and Khuvsgul are high prevalence with over 3-5 times the average. But in Dornod, Bayan-Ulgii, Dundgobi, Zavkhan, Uvurkhangai, Khentii aimags didn’t have a case of myotonic dystrophy in their population. The rest of aimags have a prevalence from 2.45 (Uvs) to 5.0 (Ulaanbaatar) per 100.000 population.Conclusion1. The relatively high prevalence of myotonic dystrophy was determined among the Mongolian population, especially in Gobi-Altai, Orkhon and Khuvsgul aimags with over 3-5 times the average. 2. The disease is spreading through reproductive way in some isolated populations. There is also a trend of increasing incidence of the disease in urban areas apparently through mechanic way rural to urban migration. 3. The study concludes that there is a need of more intensive response to fight and prevent this disease through upgrading to the modern neurological and genetic diagnostics of the disease, and their regular and sustainable application. Consequently, there is also should be need to create and improve clinical and genetic counseling for patients with this disease.

Background. The prevalence of hereditary spastic paraplegia or Shtrumpel disease is very various in studied countries of the world. It fluctuated between 0.43 (Bulgaria) and 72.4 (South African Republic) per 100’000 population.Method. In this study which is a part of a general epidemiological study of some hereditary neurological diseases in Mongolia since 1997, authors established the prevalence of myotonic dystrophy among 1.7 million population from 14 aimags and the capital city Ulaanbaatar during the period from 1997 to 2010.Goal. The study aimed to establish the prevalence of hereditary spastic paraplegia (HSP) in Mongolia.Material and Method. This study is part of a general study of the epidemiology of hereditary neurological diseases in population of 14 aimags (provinces) and the capital city Ulaanbaatar (the total population covered by the study was 1’738’000) which is being carried out since 1997. The sizes of population in aimags and the city ranged from 47,800 (Southgobi) to 605,292 (Ulaanbaatar). This study report extrapolates the prevalence nationwide. Diagnosis was established by mainly clinical characteristicsResult. Study revealed 47 patients from 15 families. The prevalence of HSP by aimags was established from 0 to 13.48 per 100’000 population (Uvs aimag). The average nationwide prevalence (1’700’000 above) was established at 2.70/100’000. There are revealed 9 cases (19.1%) in ages of 0 and 14, 6 cases (12.8%) in ages of 14-19, 27 cases (57.5%) in ages of 20- 49 and 5 cases (10.6%) in age above 50.Conclusion1. By prevalence of HSP Mongolia belongs to countries with average prevalence. But the prevalence rates differ by aimags. Patients with HSP in Ulaanbaatar (11 cases) were covered by molecule-genetic analysis by types of the disease, revealing occurrences of II and IV subtypes. 2. Of all patients, 90% are below 50 years of age pointing to the early morbidity with this disease in the context of their early mortality. The situation reveals the need of further moleculegenetic and clinical studies of the types of this disease and of improvement of clinical and genetic counseling of HSP patients.

BACKGROUND: The study of epidemiology of hereditary neurological diseases in Mongolia began a few years ago. Itcovered a few aimags (provinces) (D.Baasanjav, 2000-2005). Previous studies have shown, that hereditary neurologicaldiseases are not rare in Mongolia and structure and prevalence of these diseases vary by aimags. Mo n g o l i ahas 21 aimags (administrative provinces), each with a population from 45000 till 110440. In some “isolated” populationsspecific neurological hereditary diseases can be marked as “indigenous”. So the epidemiological study of hereditaryneurological diseases in Mongolia is one of the urgent medical shortcoming in Mongolia.MATERIAL AND METHOD: We used descriptive epidemiological method for revealing hereditary neurological diseases infamilies in population of 8 provinces (aimags) of Mongolia, Bayan-Ulgii, Bayankhongor, Govi-Altai, Zavkhan, Dundgobi,Khentii, Orkhon, Uvurkhangai, total of 627,000 population. The population of these aimags fluctuated in the range from47959 (Dundgobi) to 110440 (Uvurkhangai). Diseases were diagnosed by neurologists using clinical and genealogicalmethods.RESULTS: The study revealed 77 patients in 40 families in the studied population with variety of neurological hereditarydiseases. The overall prevalence of hereditary neurological diseases for 100,000 population is 12,26. The prevalencevaries by aimags from 2,08 (Dundgobi) to 32,50 (Gobi-Altai) per 100.000 population. The prevalence and their rangeby nosological structure per 100000 population in aimags are: myotonic dystrophy 5.41 widely varying by aimags: from4.66 in Bayankhongor to 27.09 in Gobi-Altai; Charcot-Marie-Tooth syndrome 1.59 and ranging from 2.08 in Dundgobito 4.66 in Bayankhongor; Duchenne muscular dystrophy -0.79 and ranging from 0.90 in Uvurkhangai to 3.19 in Bayan-Ulgii; the limb girdle muscular dystrophy -0.95 and ranging from 1.81 in Uvurkhangai to 4.66 in Bayan-Ulgii; Strumpellfamilial spastic paraplegia -0.95 for total pop and ranging from 2.71 in Uvurkhangai to 5.41 in Bayankhongor; familialparoxysmal myoplegia -0.79 for total pop. and range from 2.22 in Orkhon to 5.41 in Gobi-Altai; spinocerebellar ataxia -0.47 for total pop. (3.91-in Zavkhan); bulbo-spinal amyotrophy -0.32(only in Bayankhongor); spinal amyotrophy of adults-0.16(only in Uvurkhangai); arthrogryposis with myodystrophy -0.63 (only in Khentii); kyphoscoliosis with myodistrophyand nanism -0.16 (1.06 in Bayan-Ulgii)A comparatively high prevalence of all neurological hereditary diseases per 100.000 pop. was established in Gobi-Altai(32.50), Orkhon-26.56, Bayankhongor-15.16, Bayan-Ulgii -11.70 rates; the low prevalence - in Dundgobi-2.08 and-Zavkhan-3.91.The hereditary neuromuscular diseases among all hereditary neurological diseases taken up 71.9% i.e 55 patients from29 families. The myotonic dystrophy is tops the list of neuromuscular diseases (61.8%)CONCLUSION: Hereditary neurological diseases have a relatively high prevalence among the population of Mongolia,specially the neuromuscular diseases; so the control of these diseases in the country is one of the special priorityproblem of the national health care.

BACKGROUND: Multiple sclerosis is spreading in population of Mongolia last 30 years. But there are rare of the date ofprevalence of this disease in Mongolia. So we have studied the prevalence of this disease in population of 8 provinces(aimags) of Mongolia in 2008 year.GOAL: To reveal and establish prevalence and clinical characteristic of multiple sclerosis (MS) in population of 8 aimags(provinces) of Mongolia.METHOD: Revealing of patients with multiple sclerosis in population was made by neurologists, which are possessedof clinical method for revealing or confirm the diagnosis and were taken in register the patients only with confirmeddiagnosis. This study was conducted in following 8 aimags of Mongolia: Bayan-Ulgii, Bayankhongor, Gobi-Altai,Dundgobi, Uvurkhangai, Zavkhan, Khentii, and Orkhon; total population of these aimags is 627762 (m-306482, f-321279). The prevalence of this disease was calculated for 100.000 populations.RESULTS: There have been revealed total 35 patients in 8 aimags. The prevalence for 100.000 population is 5,57 (m-2,61; f-8,40) and has been fluctuated in provinces in range from 1,81 (Uvurkhangai aimag) till 13,28 (Khentii aimag) for100 000 population.The rest 6 provinces (aimags) have prevalence in range from 4,17 (Dundgobi) till 6,38 (Bayan-Ulgii).All patients were distributed by clinical characteristic in next main forms:Cerebro-spinal form in 22 patients (62,8%) among them optico-myelitis in 9 cases (40,9%); Spinal form in 6 patients(17,1%); Cerebral form in 4 cases (11,4%); only optical form in 3 cases (8,6%).Pure spinal, cerebral and optic forms are diagnosed in patients, which have duration of disease no more 6-7 years.By the courses of disease all patients distributed in courses the beginning with acute attack incomplete recovery(remissions) revealed in 18 patients (51,4%), more rapid but steadily progressive course in 5 cases (14,3%), acutesevere attacks course in 5 patients (14,3%).CONCLUSION:1. Multiple sclerosis is spreading in population of Mongolia in last 30 years after 1980.2. The prevalence of this disease in population of 8 provinces (aimags) of Mongolia in 2008 year is 5,57 cases (inmen-2,61; in women-8,40) for 100.000 population. The rates of prevalence of the disease by aimags are oscillated inrates from 1,81(Uvurkhangai) till 13,28 (Khentii) for 100.000 population.3. The women suffered more in 3 time than in man and optic form revealed in 34,2 % cases (in 12 patients). Theage of beginning of the disease was fluctuated in age from 16-19 years old till 60 above years old.4. By level of prevalence of this disease Mongolia now is belonging to countries of the world, which have lowprevalence of this disease (till 10 per 100.000 pop).

Background: The data of prevalence of epilepsy in rural provinces among general population in Mongolia is rare. Goal:The study aimed to identify prevalence rate of epilepsy and its characteristics by age and sex among the population in eight provinces (Bayan-Ulgii, Bayankhongor, Gobi-Altai, Zavkhan, Uvurkhangai, Dundgobi, Orkhon and Hentii) of Mongolia.Material and Мethod: This study in the listed aimag populations was carried out by retrospective application and using a questionnaire developed according to a methodology approved by the Academic Council of the Medical Science Institute. For verification of the epilepsy diagnosis, the study based on neurologist examination and EEG. In some suspect cases we used neuroradiological tests including СT and MRI. The diagnosed patients were registered using a special form. The study involved diagnostic examinations of 627762 (306482 males; 321280 females) persons that had at least two unprovoked seizures in their lives. For each case of positive diagnosis we calculated the prevalence rate per 1,000 population in each category of extended age groups (1-12 months, 1-2, 3-4, 5-6, 7-8, 9-10, 11-12, 13-15, 16-17, 18-22, 23-27, 28-32, 33-37, 38-42, 43-47, 48-52, 53-59, and above 60) and by sex.Result: There were 1407 cases (785 males; 622 females) of diagnosed epilepsy among the studied population. The cumulative prevalence rate for all aimags was studied 2,24 (males- 2,56; females-1,93) per 1,000 population. The relatively high prevalence rates per 1,000 population were observed in Gobi-Altai (5,14), Dundgobi (3,31), and Orkhon (2,48) whereas the lowest rate was in Bayankhongor (1, 38). A differential look by sex reveals a high sex gap 6,20 for males and 4,12 for females in Gobi-Altai while Dundgobi (males- 3,84; females- 2,80), Orkhon (males-2,91; females-2,08); Uvurkhangai (males -2,20; females -1,73) show little difference by sex (P>0,05).As for the differences by the detailed age groups, all aimag data shows that prevalence for males ranges between 0,14(1- 12 months) and 5,17 (48-52) and for females between 0,24 (above 60) and 3,82 (38-42). The highest prevalence rate among male population was observed in 48-52 age group, 6,21/1000; followed by age groups 33-37 (2,93/1000); 53-59 (2,84/1000); 38-42 (2,81/1000); and 18-22 (2,38/1000). The highest prevalence rate among female population was observed in 43-47 age group 5,49/1000 followed by 38-42 (5,48/1000); 33-37 (4,0/1000); 53-59 (3,35/1000).Epilepsy prevalence in age groups younger than 11-12 tends to fall for both male and female population. Gender difference in prevalence is that males tend to have higher rates 2,56 than females 1,93 ( P<0,05).Conclusion:1. The general epilepsy prevalence among some rural populations in Mongolia is 2,24 (M -2,56; F-1,93) per 1,000 population.2. The cumulative by all studied aimags data reveal relatively high prevalence rate in age groups of 18-59. This level might be related to men’s vulnerability to traumas and factors of vascular origins while in women it might relate to their physiological transformations of pregnancy delivery and menopause.3. Epilepsy prevalence in age groups under 12 years old tends to fall for both male and female population which might be related to the low level of examination and diagnosis of these diseases among children.4. Compared to some foreign scholars’ data, Mongolia’s epilepsy prevalence rate does not qualify it among the high rate countries.

BACKGROUND. Annular elastolytic giant cell granuloma (AEGCG) is a rare skin disease, characterized by loss of elastic tissue due to elastophagocytosis by multinucleated giant cells in the upper part of dermis, which clinically presents as multiple annular plaques with raised erythematous border and central atrophy. We report a first case of AEGCG in dermatology practice in Mongolia. Its clinical and histological features, differential diagnosis and treatment modalities are described and discussed in detail.

Background: The prevalence and incidence of allergic rhinitis is increasing in the last years in the Asia Pacific countries and for this reason, the number of research in aeroallergen and aeropollinology increasing. It depends on changes of geography, weather and plants, pollination period of time and air pollution.Goal: The aim of this study was determined allergenic characterization of proteins detected from Bromus inermis pollen.Mаterials and Methods: To define morphologic characteristics of Bromus inermis grass pollen and allergenic protein amounts’ of pollen and protein components.- The pollen morphologic characteristics of the Bromus inermis were defined and measured by optic microscopy (Aristoplan, Leitz, Germany).- The allergenic protein components of the Bromus inermis pollen were purified by the method of Hames, Richmond- Protein contents were measured by the Bradford method- The protein components of Bromus inermis pollen were determined by the SDS-PAGEResults and discussion:The diameter of the B.inermis dry pollen were mean length 41, 5±2, 3 μm and mean wide 32, 3±4, 1 μm. B.inermis dry pollen has oval and sphere shape and concaved on 3 sides with diameter 32.3-41.5 μm and was similar results one of subfamily of the Gramineae, Poaceae pollen size were defined 22-80 μm in diameter and with oval and sphere shapes. We were defined 1.5±0.02 mg protein amounts in the 5mg/ml extracts of the purified of the Bromus inermis pollen. Researcher [3] determined 1, 45 mg/ml protein on Elymus chinensis, 1, 96 mg/ml protein on Artimesia sieversiana, 3, 29 mg/ ml protein on Chenopodium album allergens. These study results are similar with our study result on Bradford method. We were defined 7 bands with 12, 26, 32, 55, 66, 84, 97 kDa molecular weight protein components. SDS-PAGE were deteсted relatively bright bands of 12, 32, 55, 66 kDa molecular weight protein components of Bromus inermis pollen proteins. Researcher Kaiser M et al were defined 16, 30, 40, 47, 50, 57, 60, 67, 70, 90, 95 and 110 kDa molecular weight bands in Lolium perenne pollen allergens. These study results are similar with our study result on SDS-PAGE. Conclusions:- The pollen of Bromus inermis was oval and sphere shapes with 32.3-41.5 μm in diameter.- We were defined 1.5±0.02 mg protein amounts in the 1mg/ml of the Bromus inermis pollen.- The 7 bands with 12, 26, 32, 55, 66, 84, 97 kDa molecular weight protein components of Bromus inermis pollen. SDS-PAGE were deteсted relatively bright bands of 12, 32, 55, 66 kDa molecular weight protein components.

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.
