Background: Development and progression of cancer is accompanied by different morphological and functional changes of cells. One of the most important changes is the expression and activity of enzymes in the cellular fatty acids metabolism that reflects in cell membrane lipid composition and increases fluidity of cancer cell membrane. The Ellipin, prepared from bovine liver, is a newly developed anticancer agent containing several important fatty acids.Goal: To investigate effects of Ellipin on hepatic cancer cell function such as proliferation, migration and adherent activity and apoptosis of cancer cell lines in vitro.Materials and Methods: This study was conducted in the Laboratory of Molecular Biology, Institute of Biology, MAS. The Ellipin was developed in the Drug Research Institute of Monos group. HepG2, HCC, 23132/87, MDCK cells lines and the primary liver cancer cells (PCC) were used for proliferation assay. Only HepG2 cell line was used for MTT, Migration, Spreading and Apoptosis assays.Results: The results of proliferation assay showed that the ellipin decreased the proliferation activity of HepG2 and PCC cells depending on concentrations; in 50μg/ml 2-3 times, 250μg/ml fully stopped cells divisions. The Ellipin reduced mitochondrial reeducates enzyme activity of HepG2 cells depending on its concentrations. For example, in 50μg/ml ellipin concentration case, the number of alive cells decreased 2 times. The migration of HepG2 cells treated with 100μg/ml ellipin was decreased by 22.3% compared to the control cells. Also the number of adhered cells was reduced by Ellipin treatment. After 50μg/ml, 100μg/ml, 250μg/ml ellipin treatment, the number of apoptic cells were 14,6%, 45,6%, 100% of initial culture cells, respectively.Conclusions: Our results showed that the Ellipin suppresses HepG2 cancer cell proliferation and decreases migration and spreading activities and also inducts the cell apoptosis.

Background: Acute appendicitis is an inflammatory disease and acommon cause of acute abdominal pain. The application of the sophisticated automated hematology analyzer more precisely define the morphology changes blood cells. According to this diagnose and treatment control issues are solved by easy and not expensive way. Recent studies haveshown that there is a negative correlation between platelet count (PC) and MPV and that theratio of these two values may be more meaningful. The aim of our study was to investigate thediagnostic value of MPV and the MPV/PC ratio in acute appendicitis. Methods: The patients were divided into two groups based on their histopathological findings: the uncomplicated and complicated appendicitis groups. Leukocyte count, PC, MPV and the MPV/PC ratio were compared all groups. Results: Total of 186 patients, including 119 men, were included in the study. The average age of all patients was 10.21±1.22 years. There was statistically significant difference of some parameters in peripheral blood between the uncomplicated and complicated appendicitis groups in terms of all index. (p<0.001). Leukocyte count had a strong discriminatory property based on the area under curve (AUC) 0.714, (p<0.001). MPV, PC and the MPV/PC ratio had weak discriminatory power with AUC values <0.663. Using receiver operating characteristic (ROC) analysis, the sensitivity and specificity of MPV were 81.56and 45.7%, respectively, and 63.78% and 71.06%, respectively, for the MPV/PC ratio. Conclusions In our study, MPV and the MPV/PC ratio were useful in the diagnosis of acute appendicitis.

Introduction: Polycythemia vera (PV) is Philadelphia chromose (Ph)-negative and chronic myeloproliferative disorder (MPN). Moreover, 0.01-2.6 incidences are diagnosed for every 100,000 population. In Polycythemia vera, guanine on 1849th base of 14th ex-one of 9th hromosome is replaced by thymidine and homozygous state is developed. As a result, valine on 617 of JH2 domain in JAK2 is replaced by fenylalanine and activation of tyrosine kinase is increased. Then, signal pathways such as JAK-STAT, PI3K/Akt and ERK1 are independently activated. The JAK2 V617F mutation is identified in approximately 95% of total polycythemia vera diagnosed cases. Furthermore, the average age group of patients with polycythemia vera is 61 and 10% of them are aged under 40 years and male:female ratio is 1:1.
In accordance with World Health Organization criteria of 2016: If three major criterias or first two criteria plus one minor criteria are identified, Polycythemia vera is diagnosed.
Although life expectancy rate of PV cases in follow-up is high, is lower in comparison with the general same age group of population and essential thrombocythemia (ET). In accordance with an international and large study (n=1545), the average life expectancy rate was 14.1 years among Polycythemia Vera diagnosed patients. More than half of mortality related to the disorder (53%) was caused by unknown etiology. On the other hand, (36\347, 10.3%), (36\347, 10.3%), (32\347, 9.2%) and (13\347, 3.7%) of the remaining mortality cases were caused by acute leukemia, secondary malignancy, thrombotic complications and cardiac failure, respectively. Objective: We aimed to determine JAK2 V617F gene mutation on patients with suspected polycythemia vera and evaluate the CBC/complete blood count/ parameters and clinical signs. Material and method: The cross sectional study was conducted during 8/Mar/2022 ad 20/May/2022 and 13 individuals with suspected polycythemia vera who received outpatient service at hematology department of State First Central hospital (SFCH) and Mongolia-Japan hospital of MNUMS were included. Ethical approval was received by order (№2022/3-02) of 28/Feb/2022 and research ethics review committee. Each and every participant received informed consents and agreed to participate in the study. The current study was conducted with the support of integrated laboratory of Clinical pathology of State First central hospital. Result Total of 13 participants were included in the study, 38.4% (n=5) and 61.5% (n=8) of them were male and females, respectively. The mean age group was 58.69±7.7 years. The JAK2 V617F mutation was detected in 92.3% (12/13) of patients. The average age group was 57.8 (52-68) for males and 58.6 (43-71) for females. Complete blood count parameters of males with the JAK2 V617F mutation are shown.
By questionnaire, some of clinical signs such as fatigue, pruritus after bath, headache, dizziness, bone and muscle pain, hands and feet peripheral cyanosis, numbness and nocturnal sweating were detected on patient with positive mutation.

Introduction: Diarrhea is defined as a person excretes more than three times in 24 hours with pathological impurities of more than 10 mg/kg per day. According to the fact sheets of the World Health Organization in 2019, diarrhea is the second leading cause of death among children under 5 years of age. Researchers suggest that about 50 percent of infantile diarrhea occurs in temperate countries and it reaches almost 80 percent in winter which is mainly caused by rotavirus. While immunization is the most effective way to prevent rotavirus infection, there were two types of rotavirus vaccines that have been licensed and available on the global market since 2006. Rotavirus immunization in young children is a safe and effective public health method for controlling rotavirus infection which therefore can reduce childhood morbidity and mortality. Study aim: To study the incidence, clinical manifestations, and complications of rotavirus among children hospitalized with acute diarrhea. Methodology: The study will be conducted using the observational method including descriptive analysis. Statistical data for 2018-2020 will be obtained and analyzed from the pediatric wards of the “Gurvan Gal” hospital. Children diagnosed with rotavirus diarrhea who meet the criteria to be included in the study will be selectively sampled with further analysis of the incidence, clinical features, toxicity, and dehydration of acute diarrhea according to the medical history. Results Universal immunization is important to significantly reduce rotavirus-associated diarrhea, thereby reducing infection and the risk of disease in infants and young children.

BackgroundIn Mongolia scientists have been doing research about skin disease and process of aging. Howeverthere has not enough study material about skin aging process which is the key indicator of aging andhow that affect to Mongolian people.GoalMain purpose is to study correlations between main index of skin type of the body, cardiovascularsystem, biological age, epidermal growth factor and blood plasma melatonin, within the people of Uvsprovincial center as they are relatively healthy people.Material and MethodsResearch works were done using cross sectional study model in years 2015-2016, within randomlychosen 400 citizens of Ulaangom city, counted to be relatively healthy people. Research model includes41 questionnaires, examination and blood plasma samples.Basic indexes of the body, cardiovascular system and respiratory functions were chosen by biomarkers,biological age is determined by V.P.Voytenko’s 4th version method and adaptive capacity assessment isdetermined by R.M.Baevskii’s multi-repeating regression method.Main skin type parameters such as porosity, wrinkles, pigmentation, elastics and aging is determined bythe “BOOMTECH skin diagnosis” digital equipment made in the Republic of Korea.The blood plasma MLT and EGF were measured by the method of ELISA analysis ELISA made in thelaboratory of the “AVITSENNA Science and Technology center”.The study material analysis carried out an analysis using logistic regression analysis and Pearson’scorrelation coefficient with SPSS 23.0 software.ResultThere’s an inverse weak correlation between blood plasma MLT and EGF with body wealth characteristicsof Uvs province citizens. It shows that when the blood plasma MLT and EGF decreases the body weight,body height and body weight index increase tendency.In women the decrease of blood plasma MLT and EGF also decreases the body height and body weightindex.Research on correlation between cardiovascular system and blood plasma MLT and EGF shows thatdecrease of blood plasma MLT causes in increased arterial pressures in both sexual groups, decreasedEGF in women causes decreased arterial pressure.Correlation study between skin main characteristics and blood plasma MLT and EGF shows thatdecreased blood plasma EGF in men resulted in decreased skin wrinkles, porosity, elasticity and skin aging index, in women decreased skin pigmentation and elasticity, and increased skin wrinkles, porosity and aging index in women.Research study of correlation between biological age and adaptive capacity assessment with the blood plasma MLT and EGF shows that decreased MLT and EGF in men results in increased biological age characteristics. In other words, the early aging is caused.The logistical regression analyses made using blood plasma melatonin, skin porosity, biological age,body height and sex as the risk parameters of Pearson coefficient and chi-squared parameter. Above model resulted in skin porosity and blood plasma MLT’s are becoming independent variable assessing the skin aging.Conclusions:1. The decreased MLT and EGF’s are resulted in increased body weight, body height and body weight index in men and decreased body height, body weight index in women.2. Decreased blood plasma MLT resulted in increased arterial pressure in both sexual groups and decreased EGF resulted in decreased arterial pressure in women.3. The decreased blood plasma MLT and EGF results in decreased skin wrinkles, porosity, elasticityand skin aging parameter with the increased skin pigmentation in men, as it results in decreasedskin pigmentation, elasticity and skin porosity parameters with the increased skin aging degree in women.4. When epidermal growth factor and blood plasma melatonin is decreased in men it results in increased biological age, but depends directly to the adaptive capacity assessment.5. Skin porosity and blood plasma melatonin were becoming independent variable to assess skin aging.

BACKGROUND. Regular blood donation can lead to pre-clinical iron deficiency as well as iron deficiency anemia. With Each donation donors lose 220-250 mg of iron. Early detection of iron deficiency is important for the blood donors and even useful for blood and blood product safety and supply. The research work we studied present Ret-HE to be used to detect the occurrence of iron deficiency eritrony level. Purpose: The aim of this study was to determine Ret-He to have sensitivity and specificity for diagnosing iron deficiency than traditional iron measurements. Materials and methods: We performed a cross sectional and case control study of 156 blood donors who served National Center for Transfusion Medicine. Ret-He, hemoglobin, plasma iron and ferritin were measured using XN2000 Sysmex, and CobasE600 Roche. The statistical analysis was done using One way Anova, Rock curve, Kruskal Wallis test. Results: We examined 64(41.02%) male donors, 92(58.9%) female donors by measurements of Ret-He,hemoglobin, serum, iron and ferritin. Survey participants were 8.33%(n=13) with anemia, 91.67% (n=143) without anemia. In donors with anemia the results were: RBC 4.9*106 u/l, HGB 10.8 g/dl (10;11), serum ferritin 5.2 (4.3; 6.3) mmol, serum iron 4.5 (3.7; 5.8) mmol and Ret-He 25.5 (22; 26) pg. Donors were divided into 3 age groups: group I age was up to 25years, group II was between 26-35 years, group III age criteria was above 35. Group I had serum iron 13.5 (10.; 18.), serum ferritin 41.8 (14; 78), Ret-He 32.2 (30; 33.) RBC 5×106 u/l (4.6;5), HGB14.2g/dl (13.3;14. 2). Group II had serum iron 14.6 (11; 19), serum ferritin 54.1 μg/l (29; 138), Ret-He 32.2pg (31; 33), RBC 5.1×106 u/l(4.7;5.1), HGB14.8 g/dl (13.5;14.8),Group III had serum iron 15.1 umol/l (9; 20), serum ferritin 95.7 μg/l (39; 141), Ret-He 32.7pg (31; 34) , RBC4.9×106 u/l(4.6;4.9), HGB 14.5g/dl(13.8;14.5), respectively. According to a curve (Roc) analysis, AUC of serum iron was 0.0963, serum ferritin 0.909, Ret-He 0.975. The mean Ret-He was 32.3pg (31.3;33.4). The optimal cut off value for the Ret-He was 29,25pg by ROC analysis and are presented along with sensitivity 92.3% and specificity 95.1%. Conclusion: 1. Determining the amount of Ret-He has a better sensitivity and specificity for diagnosing iron deficiency compared to traditional iron measurements. 2. Ret-He has diagnostic indicators that are able to detect the depletion of iron reserves, erythron level. And it need to be used in further clinical practices, as well as doctors should be required to use it for diagnosis and treatment.

BACKGROUND. Previous retrospective study from our team showed that RDW significantly increased in chronic heart failure (CHF). OBJECTIVE. The aim of the study was to compare the value of RDW-CV with NT-pro BNP and evaluate sensitivity and specificity of RDW for diagnose of heart failure. MATEREALS AND METHOD. Here, we analyzed 20 patients who were suffering from heart failure and were treated in the department of Cardiology, First Clinical Hospital between in June 2017. All patients in the study group were underwent a complete blood count, immunoassay for NT-proBNP. The ejection fraction was analyzed by ECHO cardiograpy. RESULTS. 85.0% of patients were male and remained was female. RBC and RDW was significantly differentially measured in between CHF groups (р= 0.028 p=0.0001). In control groups without heart failure NT-proBNP was estimated up to 100 pg/ml, whereas it was definitelly increased in patient with CHF (р=0.0001). There was strong correlation between RDW and NT-proBNP (r =0.846, p=0.0001). sensitivity and specificity of RDW was 89%, and 74.3 % respectively in CHF. CONCLUSION. According to the our results there was direct correlation between RDW-CV and heart failure (p=0.035). RDW-CV migh be cost effective and routine laboratoty marker to evaulate CHF.
