BACKGROUNDThe use of stem cells for 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 form a 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 stemness.METHODSBone marrow cells from 8-10 week aged mice were subjected to hypoxic conditioning by culture for 7days in 20%, 3% and 1% oxygen. For culture,1x105 cell/ml were seeded in colony forming assay in each dish. During the culturing, cell colonies were checked once every three days. Compared to normoxic cells, hypoxic cells weremorphologicallyundifferentiated and counted by Olympus IX71 microscope.RESULTSMore colonies were observed at 3% and 1% oxygen. Statistical significances were identified with granulocytes and macrophage colony (p<0.05) in hypoxic condition.CONCLUSIONSOur data suggests low physiological oxygen culture could improve the stemness of macrophage and granulocytes colony. Long term culture will be necessary to confirm whether low physiological oxygen levels also improve genomic stability.

Background:Mesenchymal stem cells derived from bone marrow and adipose tissue are being applied to tissue engineering and cell therapy. 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 marrowmesenchymal 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 mesenchymal stem cell. Results:BMCs from 8-10 week aged, 6 mice were subjected to hypoxic conditioning by culture for 7 days in 20%, 3%, 1% oxygen. For culture 1x106 cell/ml were seeded in media with L-glutamine in each dish. During the culturing, cell colonies were checked once in three days. After cell culture, we stained cells by CD90 then counted CD90 positive cells by fluorescence microscope. More colonies and mesenchymal cells were observed at 3%, 1% oxygen and also colonies were bigger in hypoxic condition. Statistical significances were identified mesenchymal cells (p<0.05) in hypoxic condition. Conclusions:Our data suggests low physiological oxygen culture could improve the differentiation of mesenchymal cells. Long term culture will be necessary to confirm whether low physiological oxygen levels also improve genomic stability.

Today, in technologically updated world medicine, laparoscopy is more preferable than the common, open surgery procedures. There is a lack of scientific studies on laparoscopic surgery in gynecology, especially its present state and further tendencies. Therefore it served us as the background of the study.Retrospective study was conducted on 2016 laparoscopic surgery histories, which were performed in 2010-2014, at Mongolian state and private obstetric-gynecological hospitals and clinics. The study was developed by the program SPSS21.In 2010-2014 totally 2016 laparoscopic surgeries was performed: 713 – in First Maternity Hospital, 653 – in Bayangol hospital, 429 - inASE hospital, 221 – in National Cancer Center of Mongolia. The patients were classified by their age, education state, and citizenship. Mean age of these patients was 33.03 ±7.6(min 12, max 70). By educations: the 72.4% (1460) of them were high educated, 18.2%(367) has the secondary education, 4.7%(95) – college education, 4.5%(91) – 8th grade education, and 0.2%(3) – elementary school education or non-educated. The 81.8 %( 1649) patients were citizens, the 18.15 %( 366) – from rural areas. And only 0.05% (1) was the foreigner. We noted 7 %( 14) cases that shifted from laparoscopic surgery to open procedure. The post surgery average bed day was 2.7 ±1.3 (min 1, max 12), duration of the laparoscopic surgery 58.46 ±31.6 minutes (min 10, max 260). The average amount of blood loses during the surgery was 76.17 ±69.3( min 5, max 700),The relevance of the surgery duration and preoperative bleeding was(r-0.445). Various diagnoses were involved in the study: the 25.9% (524) of them had second infertility, ovarian endometriosis cyst- 10.5% (212), ectopic pregnancy- 9.4% (189), hydrosalpinx- 7.5% (152), endometrioma ≥ 4.5 cm - 6.3% (128), ovarian follicularcyst- 6.3% (128), ovarian cancer- 5.7% (115), primary infertility- 5% (101), ovarian dermoids cyst-4.3% (86), endometrioma ≤ 4.5cm- 3.4% (68), others-15.7%. Surgical procedures are classified by their purposes: 29% (584) of surgery for examine the fallopian tube using contrast for medium and divide adhesion, 17.6% (354) – to remove ovarian cyst, 12.8% (259) – to examine fallopiantube using contrast and remove ovarian cyst, 9.4% (189) – to remove fallopian tube, 7% (142)- to remove endometrioma, 6.3% (128) – to examine uterine tube using contrast dye, 6% (121)-ot do hysterectomy, 11.9%- for other reasons. The 76.7% of all surgeries were done within one hour and there was moderate correlation between duration of surgery and bleeding (r-0.445). The secondary infertility was the most common diagnosis. And the laparoscopic manage of adhesion and hystersalpingography were performed more. According to the study, non-cancerous growth of uterus was 9.7 and the 6% of it surgeries was laparoscopic myomectomy.

IntroductionNowadays the risk factors for thrombosis include blood stasis, vessel wall injury, and hypercoagulability, as proposed by Virchow over 150 years ago. We chose to study affect of Zomoshin 6 tan to the model of thrombosis formed in experimental animal. It was written in books and sudar that it has action of treating some type’s disease such as blood diluting, meeting frozen blood and treating some gynecological disease.PurposeTo study affect of Zomoshin-6 tan deep vein thrombosis model formed in experimental animal.Material and Methods30 male rats of wistar bread with 180-220 gram of weight for control group, experimental group or Zomoshin-6 tan and comparative group Warfarin. Thirty rats were equally divided into 3 groups: Group 1 received saline alone, Group 2 received Zomoshin-6 (200 mg/kg), and Group 3 received Warfarin as a positive control (0.25 mg/kg), seven days prior to the assessment of thrombus formation. Thrombus formation was also assessed histopathologically. Thrombi were detected in all rats after experimentallyinduced thrombosis.ResultsHistological analysis demonstrated the presence of thrombosis in the interior vena cava (IVC) of the control group, which contained fibrin, erythrocytes, and leucocytes and obstructed the lumen. Only a small amount of fibrin clot, containing a few leucocytes and large numbers of erythrocytes, were observed in the Zomoshin-6-treated group. The thrombus formed in the IVC of Warfarin-treated animals consisted of fibrin clot, which was mostly attached to the wall, with few leucocytes but abundant erythrocytes. These findings suggest that Zomoshin-6 is an effective antithrombotic agent.Conclusion:Zomoshin-6 tan has an action of inhibing thrombosis forming of vein in experimental animal.

Introduction. Stigma and discrimination against patients with mental illness is very common amongst the society. Therefore, this study aims to study the knowledge and understanding of mental illness and attitudes to patient with mental illness, among the general population.Goal. To assess the knowledge and understanding of mental illness and attitude to patient with mental illness among population of Ulaanbaatar city and compare its results with a similar research in carried out in 2002.Methods. The study was conducted in Ulaanbaatar city from February to April, 2008 and included 991 people aged over 18 years. The sample was selected from 30 micro districts of Ulaanbaatar city, The method of sampling was using primary dot in first step, sampling households in mid step and selecting people by using method of Sweden key from household in final step. The study used 30 item standardized questionnaires. Also there were 2 extra cards to read for respondents.Result. Among the respondents, 45% were males and 55 % females. Average age was 37 years. In view of identifying negative attitude of patient with schizophrenia, majority of respondents answered as “loony person” (n=136) and “mad person” (n=83). Conclusion. Although there was stigma amongst the study population, 66% of subjects who were involved in study could give right diagnosis in non professional level and were able to identify symptoms of mental illness suggesting that more than half of the sample studied had some knowledge of mental illness.

Background: Plants have played a significant role in maintaining human health and improving the quality of human life for thousands of years and have served humans as valuable components of seasonings, beverages, cosmetics, dyes and medicines. There are a number of medicinal plants used in the traditional medicine in the Mongolia to form “tan” prescriptions which are mostly consist of the mixture of individual medicinal plants and used by nomads during the long history for their health care as medicines. Lancea tibetica (Scrophulariaceae) is a traditional herbal medicinal plant in Mongolia, China and Tibetan. In Mongolian traditional medicine, L.tibetica different exclusive forms of preparations are effective for treatment of some disorders such as pulmonary, cough and heart disease. Aim: This study aim was to define the biochemical some composition antibacterial activity and mineral elements content in air-dried samples Lancea tibetica of Mongolia. Material and Method: The antibacterial activity and Minimal Inhibitory Concentration (MIC) of the extracts was collected of the seed, aboveground part and root for the Lancea tibetica. From three different organs of plant Lancea tibetica was collected of the Tsenkher district Arkhangai province (2017.07.28) and Tunel district Khuvsgul province (2018.08.27) were evaluated by means of the Disk diffusion method against five bacteria (Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Micrococcus luteus, Enterococcus faecalis). We have taken extracts of plant 3 organs from organic solvent (7) ethyl acetate, hexane, n-butanol, methanol, chloroform, ethanol and distilled water for antibacterial activity. MIC of the extracts were defined and compared with each other. The macro-and microelements were determined by X-ray fluorescence spectrophotometer analysis (XRFA). Result: We have taken a dried seed, aboveground part and root of Lancea tibetica in the investigation. In these three samples were determined biochemical composition of 11 components for quantitative analysis: moisture was 6.2±0.2%, ash 4.8%, protein content was 1.67±0.1%, raw oil 5.9±0.3%, reduction sugar 0.39±0.1%, vitamin Р 16.6±1.8 mg%, extractive substances 18.6±0.2%, tanning matter 0.05±0.02% and flavonoids 0.2±0.01% in seed. The same moisture was 6.7±0.4%, ash 9.7%, protein content 1.89±0.2%, raw oil 6.1±0.8%, reduction sugar 0.52±0.1%, vitamin С 3.52±2.2mg%, vitamin Р (rutin) 20.3±0.2mg%, carotene 12.8mg%, extractive substances 16.8±0.1%, tanning matter 0.08±0.01% and flavonoids 0.6±0.24% in aboveground part. Besides this, in root: the moisture was 6.1±0.3%, ash was 14.9%, protein content was 2.1±0.3%, raw oil was 2.9±0.2%, reduction sugar 0.62±0.02%, vitamin Р 17.8±0.05mg%, extractive substances 20.3±0.4%, tanning matter was 0.06±0.03%, flavonoid was 0.35±0.002%. Besides this, we revealed the saponin by method quality analysis in aerial part and root of Lancea tibetica. But not triterpenoid saponin in seed. The same not revealed alkaloid all the samples.
Eighteen extracts (5mg/disc) of three organs (seed, aerial parts and root) showed antibacterial activity diverse. The MIC in ethanol and butanol extracts of seed, aboveground part and root was more than others.
From thoroughly air-dried aboveground part samples of Lancea tibetica from Tsenkher district of Arkhangai province and Tunel district of Khuvsgul province. We determined the 43 mineral elements. 11 elements were defined by percentage, 10 elements were oxide forms (SiO₂, TiO₂, Al₂O₃, Fe₂O₃, CaO, MgO, Na₂O, K₂O, MnO, P₂O₅) of them. Other elements were defined by mg/kg unit. The same heavy metallic, mobile elements (Cu, Cr, Zn, Mn, Pb, Ni, Co) and rare earth elements (Ce, La, Nd, Pr, Sm) were determined. Conclusion In the result of this research work to determine the content of biologically active substances in Lancea tibetica. Plants produce a great variety of organic compounds that are not directly involved in primary metabolic processes of ground and development. Study of the biochemistry of plant natural products has many practical applications. Various detectable contents of useful or macronutrient and micronutrient oxide was found in the ash of aerial parts. Some macronutrient and micronutrient elements were detected by oxide forms.

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

Backround: Hematology departments of health laboratories, over capital city and 21 provinces both of governmental and private sectors in this country, have to take responsibilities for providing hematology analysis. A wide range of technology and methods have been implemented among these laboratories. Harmonization of the hematology investigations of different laboratories with standard service all over the country is the major goal to reach. We organized the MEQAS (Mongolian External Quality Assessment Scheme) since 2008 on basis the Cooperation agreement between Ministry of Health and Sysmex Corporation in the establishment of Hematology external quality control and reference laboratory system in Mongolia. This is the report of our 8-year experience of MEQAS as the national project, covering increasing numbers of laboratory members. In 2008-2017 years we set up total 18 MEQAS in Mongolia. Materials and Methods:
Survey Materials
In each survey, the following three different of survey materials were used;
Sample A : Hematology Control Material 1*
Sample B : Hematology Control Material 2*
Sample C : Fresh Whole Blood Sample**
*Hematology Control Material provided by Sysmex Corporation
**Under cooperation of National Center for Transfusiology, a fresh whole blood sample was drawn from a healthy donor and prepared on the same day of sample delivery, according to the procedures reported by Kondo H et. all.
Standard Analyzers
3 units of fully-automated standard analyzers (KX-21, pocH-100i, XS-1000i), installed at the Shastin Central Hospital, were used to assign the target values for the survey materials. These standard analyzers have been calibrated with SCS-1000® before the survey, and monitored with hematology controls, e-CHECK(XS) ® and EIGHTCHECK-3WP® on daily basis.
Instructions & Sample Distribution
On every survey, the workshop was held to give guidance and distribute the survey samples to each participant.
Categorization of Peer Group
Participating data were divided into two peer groups, based on methodology; Group 1: laboratories used automated hematology analyzer (in further Auto’s), Group 2: manually examined group. Each laboratory was given ID number and was asked to analyze these samples 3 times and report the all data and average for CBC 8 parameters.
Statistical Evaluation Method
For individual reports, the results for each participant were evaluated and expressed according to peer group mean and standard deviation index (SDI), Precision index (PI), Absolute evaluation, Scoring system and Target-value evaluation methods (A B C D evaluation). Results:
