ABSTRACT
Introduction@#Due to social transition and change of many societal activities in Mongolia, there is an increasing need for pharmaceutical drugs to treat anxiety, stress, fatigue and insomnia. It is considered that medicinal plants used in traditional medicine as sedatives, anti-anxiety and anti-depressive activities could be effective. Our study focuses on exploring optimal methods for preparing tinctures from <i>Paeonia</i> L. genus species, a sedative in Mongolian traditional medicine, and studying their phytochemical compositions.@*Materials and methods@#Root and herb of <i>Paeonia anomala</i> L., grown in Mogod soum in Bulgan province, were used for the study.</br> Prepared herb and root were chopped and sieved into 1 mm, 2 mm, 3 mm, 4 mm and 5 mm sizes. Then from each size of two samples, a set was created with a 1:1 ratio. Finally 40 % ethanol (1:10 ratio with a set) was applied to prepare tincture through a traditional maceration method. The obtained tincture was analyzed for its color, quantity of biologically active compounds, dry residue, and absorption coefficient using an optimal particle size of samples, volume of the extractive liquid and tincture yield.</br> Tincture from the set of herb and root of <i>Paeonia anomala</i> L. was prepared using 3 methods, namely, by the traditional maceration; intensified maceration using the ultrasonic bath processing with 45 kHz at an ambient temperature; constant shaking in a heat of 30o-40oC. @*Conclusion@#The more optimal and effective method for preparing tincture from <i>Paeonia anomala</i> L. has been found to be the ultrasonic bath processing with 45 kHz for 6 h at an ambient temperature. Crude drug mixture of 2 mm sizes with 40% ethanol (where volume absorption coefficient was accounted to be 2.8) was mixed at a ratio of 1:10. In the obtained tincture, total phenols were determined as 0.58±0.003% in gallic acid equivalent and total monoterpene glycosides as 1.96±0.002% in paeoniflorin, which were the highest compared to other methods, indicating the method is the more optimal one.
ABSTRACT
Introduction@#Over 800,000 people in the world contract HCC each year and approximately 700,000 die from the disease. HCC is the 6th most common cancer in the world. HCC is the 3rd leading cause of cancer deaths in the world. 2/3 of liver cancer deaths are caused by hepatitis. In the U.S, HCV infection is the more common cause of HCC, while in Asia and Africa, HBV is more common. Mongolia ranks first in the world in mortality from liver cancer, indicating the need for early detection and treatment of cirrhosis. Sysmex Corporation has introduced for HISCL series analyser, a new cirrhosis marker M2BPGi of non-invasive, blood-testing. In 2016, the test was introduced at Medipas Hospital in Orkhon province. It is possible to study the advantages and significance of the marker for use in clinical practice.@*Materials and methods@#From a total of 385 patients who underwent M2BPGi marker testing in 2016-2017Medipas hospital laboratory, data from a total of 283 patients tested for hepatitis B and C virus and M2BRGi markers were selected. A comparison of age, sex, and test parameters of a total of HCVab and HBsAg positive 172 patients tested for Total bilirubin, GPT, GOT, GGT, AFP and M2BPGi. HCV Ab, HBsAg, AFP, M2BPGi markers were analyzed by SysmexHISCL-5000 fully automated immunological analyzer, Liver function tests were performed with a fully automatic biochemical analyzer JEOL Biomajesty BM6010/C.@*Results@#Of the M2BPGi marker tested 283 patients 94 (33%) were infected with the C virus, 78 (28%) were with the B virus,11 (4%) were co-infected with B and C viruses, 100 (35%) no any viral infection. Of the 172 patients diagnosed with hepatitis B and C virus infection, 97 (56%) were male, 75 (44%) were female. In terms of age, 72% of the population is over 45 years old.</br> Of the 172 patients, 115 (67%) had M2BPGi marker abnormal or > 1.0 COI. Of the M2BPGi marker abnormal patients, 47 (41%) were infected with the B virus and 68 (59%) with the C virus. In terms of age, 27.7% of hepatitis B patients and 10.3% of hepatitis C patients were under 45 years of age, 72.3% of hepatitis B patients and 89.7% of hepatitis C virus patients were over 45 years of age.</br> Hepatitis B and C viruses are slightly more common in men than in women. The majority of patients infected with the hepatitis virus over the age of 45. The majority of patients with hepatitis virus have abnormal liver function. Increased M2BPGi markers in people under the age of 45 with hepatitis B virus infection are relatively higher for hepatitis B virus infection than for C virus infection.@*Conclusions@#The M2BPGi marker was abnormal in 67% of hepatitis virus infected patients. It has been observed that the probability of an increase in M2BPGi marker is slightly higher in hepatitis C virus infection than in hepatitis B virus infection.
ABSTRACT
Background@#A blood product is any therapeutic substance derived from human blood, including whole blood and other blood components for transfusion, and plasma-derived medicinal products. Medicinal (medical therapeutic) products derived from human donations of blood and plasma play a critical role in health care. Safe, effective and quality-assured blood products contribute to improving and saving millions of lives every year, as they: address child mortality and maternal health, dramatically improve the life expectancy and quality of life of patients suffering from life-threatening inherited disorders, such as haemophilia, thalassaemia and immune deficiency, and acquired conditions such as cancer and traumatic haemorrhage and support complex medical and surgical procedures, including transplantation. An insufficient or unsafe blood supply for transfusion has a negative impact on the effectiveness of key health services and programmes to provide appropriate patient care in numerous acute and chronic conditions. Ensuring access of all patients who require transfusion to safe, effective and quality-assured blood products is a key component of an effective health system and vital for patient safety.</br> Although the number of blood donors is increasing, there are still insufficient human and financial resources for encouraging the growing demand of blood and blood products and new blood donors. @*Material and Methods@#We collected secondary data by using using the order forms of hospitals that used blood and blood products registered in the National Center for Blood Transfusion Research in 2017-2019 in accordance with the retrospective survey method. </br> In total 34,119 hospital order information sheet was entered into computer in excel program, and converted into SPSS 23 software, descriptive parameters were calculated and analyzed. @*Results@#Compare to the 2017 (n=9076), the demand of blood product was increased by 21.8%, and 54.8% in 2019. There are 51.9% (95%CI: 51.2-52.5) of total users are male, which is statistically significant. The mean age of blood product users were aged 48.58±21.32, the youngest user was aged 1 and the oldest age was 99. The demand of blood products were increased by growing of the age of users. The product usage of age group of 46-55 was 17.8% and has trend to increase year by year. In total, 11.3% of total blood product was utilized for children and 72.3% of them were aged less than 5 years old. 73.0% of total blood products were utilized in specialized hospitals, 14.6 % of them were used in aimag and district level hospitals and 11.3% of them were used in private clinics. 24.4% of blood products utilization was used for diseases of digestive system (К00-К93), 22.1% of them were used for diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism, and 19.5% of them were used for the cancer (C00-C97) disease patient’s treatment. @*Conclusion@#Since after new treatment guidance was introduced the blood and blood products usage had been increased.
ABSTRACT
Introduction@#Urinary tract infections (UTI) are at the second place in the frequency of all causes of infection after respiratory ones. The UTI requires appropriate antibiotic treatment. 85% of UTI predictive antibiotic treatment without confirmation by bacteriological analysis. This is one of the major causes of drug resistance, especially in K.coli. Urine bacteriological tests do not show bacterial culture in all cases where the number of bacteria in the urine exceeds the reference level. Therefore, there was a need to establish criteria for urine bacteriology test based on the results of urine sediment analysis.</br> In 20I7, a new fully automated Sysmex UF-5000 urine sediment analyzer was installed in the laboratory department of Medipas Hospital. The features of this analyzer include counting the number of bacteria in the urine, distinguishing between gram-positive and negative, homogeneous and mixed forms, and counting the formed elements in the urine. This feature made it possible to compare the number of bacteria and leukocytes in the urine with the results of urine bacteriology tests.@*Goal@#Determine the relationship between the number of white blood cells and bacteria in the urine measured by the Sysmex UF-5000 urine sediment analyzer and the results of the urinary bacteriological test.@*Objectives@#Compare the number of urine bacteriaand leukocyte measured by using the Sysmex UF-5000 urine sediment analyzer with the urine bacterial culture, and calculate the correlation.@*Materials and methods@#The study is analytic cross-sectional study, analyzed the results of a total of 159 people who analyzed a urinalysis and urine bacteriological test at the Medipas Hospital Laboratory in 2017-2019 years.Urine samples were collected in a 100 ml, disposable sterile container in accordance with the instructions for taking urine midstream.Urine analysis was performed within 2 hours of sampling with a fully automatic urine sediment analyzer Sysmex UF-5000 Japan. Urine bacteriological analysis was performed on a lul sterile loop of urine specimens, inoculated into 5% blood agar from Hungary's BioLab, Sabouraud agar, and Chromogen agar from Biomerieux France, and incubated for 24 hours in an incubator at 37°C. Bacterial identification and antibiotic susceptibility tests were analyzed using the "Vitek-2" analyzer from the manufacturer Biomerieux France. Bacterial and leukocyte counts data measured by the Sysmex UF-5000 analyzer and urinary bacteriological analysis data were performed using SPSS23 software.@*Results@#A total of 159 urine samples were tested for bacteriological analysis, of which 81 (50.9%) were bacteria over 105 CFU/ml or urine positive culture UTIs, 78 (49.1%) were nonsignificant bactcruria and urine negative culture.The average number of bacteria measured in the urine of 81 samples with urine positive culture above 105 CFU/ ml was 46491/ul (1168-100000 BACT/ul). </br> The average number of bacteria measured by the urine sediment analyzer of 78 samples with urine negative culture was 2645 BACT/ ul (2-57280 BACT/ul). To calculate more accurately estimate the average number of bacteria in 81 urine specimens with positive culture, the average number of bacteria in 17 (21%) samples was 4753 BACT/ul, measured in relatively low bacteria numbers of 1168-9450BACT/ul. The average leukocyte number in the urine of 81 samples with positive culture was 472.2 WBC/ul, and the average leukocyte number in the urine of 78 samples with negative culture was 87.7 WBC/ul.There is a strong correlation between the number of bacteria measured by the urine sediment analyzer and urine bacterial positive culture, which is 0.8 or statistically significant (p<0.001).The correlation coefficient of the number leukocytes measured by the urine sediment analyzer with in the urine positive cultureof bacteriological tests was 0.6 or moderately of statistically significant (p=0.005).There is a statistically significant relationship (p=0.001) between the number of bacteria in the bacterial positive culture population and the number of leukocytes.@*Discussion@#Of the 81 cases of urine bacterial positive culture, 78 (96%) were female, indicating a high prevalence of UTI among women. According to the results of the Fabio Manon's study, the number of leukocytes in the urine is 160-340 WBC/uL and the number of bacteria is 15000-30000 BACT/u,L in the case of UTI, which is approximate results compared to the our study results.Based on the results of the urine sediment analysis, indications for a urine bacteriological test should be made.</br> Based on the results of urinary bacteriological tests, the choice of antibiotic treatment is the best treatment for urinary tract infections and a way to prevent of antibiotic resistance to UTI.@*Conclusions@#The number of bacteria measured by a Sysmex UF-5000 urine sediment analyzer is directly related to the bacterial culture urine bacteriological test. If the number of bacteria in the urine is measured above 4753 BACT/ul, it can be considered as an indication for urine bacteriological analysis. Although the number of leukocytes in the urine measured by the Sysmex UF-5000 urine analyzer is moderately correlated with bacterial culture in urine bactcriologucal tests, it is a key indicator of the degree of inflammation of the urinary tract.
ABSTRACT
Background@#Blood is an important resource, both for planned treatments and urgent interventions. It can help patients suffering from life-threatening conditions live longer and with a higher quality of life, and supports complex medical and surgical procedures. According to WHO recommendation at least 1% of the population of any country needs to donate their blood to accommodate the basic clinical needs of the country. Accordingly, we aimed to assess existing attitudes of the general population towards on blood donors. @*Materials and Methods@#The survey identified attitude of the population on blood donation and factors influencing them, using quantitative and qualitative methods. The survey covered a population aged 18-60 years. SPSS software version 21 was used for data analysis of the survey. The survey protocol and methodology were reviewed and approved by the Scientific Committee at the NCPH. The Medical Ethical Committee at the MOH reviewed the survey materials and issued an approval (2015/3). @*Results@#The survey covered in total 3,782 people and there are 59.2% of surveyed respondents said they have never thought of becoming a voluntary blood donor. Positive attitude on blood donation is higher with statistical significance among women (59.0%), 18-25 years old (43.7%) and UB residents citizens with higher education. As education level increases the number of respondents who thought about donating blood is also increases. 16.1% of them had a history of blood donation before and 38.2% said they never thought about it. Twenty point four percent of respondents thought blood donation brings some kind of risk. Nevertheless of the education level of surveyed respondents, the percentage of answer blood donation is not risky for a person was the most common answer. But respondent who is only literal and uneducated were don’t know about whether it has a risk or not (385.37=2א, p=0.000001). Also, respondents failed to donate their blood because the family not allowed, afraid, risk of infection, doesn’t want and had a busy schedule.@*Conclusion@#There is a high tendency to donate blood populations of young people aged 20-29, women, residents of Ulaanbaatar, and uneducated and highly educated. The majority of respondents agreed that blood donating is charity and a good deed. The leading causes of blood donation is the education, gender, the desire of doing a good deed, peer influence and health condition.
ABSTRACT
@#The incidence of oral cancer is differed in the world. Oral cancer incidence was high in Melanesia, South-Central Asia, East and Central European countries,3 while it was likely to be low in Africa, East Asia, and Central American countries. Our study purpose was to determine the risk factor of tongue cancer and to study between correlation T, N stage and type of tongue cancer. The study was carried out by retrospective method, by using the medical reports obtained from the National Cancer Center of Mongolia. This study, based on retrospective method was conducted from medical reports of 68 patients who were diagnosed with squamous cell carcinoma of the tongue and at the Department of Head and Neck Surgery, Radio and Chemotherapy of the National Cancer Center of Mongolia between 2005 and 2014. The data was analyzed using SPSS 20.0 software; descriptive and detailed statistical analysis was made. Assumptions were examined by H2 testing method; it shall be statistically significant when P value is less than 0,05. The median age of the 68 patients at diagnosis was 58 years (range=31-85 years) and were 57% (39) men, 43% (29) women with a male to female ratio of 1.3:1. Of 37 patients who were tobacco users 66.7% (26) were male, 37.9% (11) were female, among the alcohol consumers (35.9% (14) were male, 10.3% (3) female). This difference between male and female consumption was significantly different according to the test Pearson p=0.019 for tobacco, p=0.016 for alcohol. There was trend toward more higher N stages in endophytic tumors, with 69.3%, in ulcerative tumors, with 66.7% of these cases presenting with nodel involvement, 45% of patients with exophytic tumors. Our study showed that oral tongue cancer in majority occur in fifth and sixth of life and with a male predominance. Smoking and drinking alcohols are two major risk factors for SCC of tongue cancer. Although not significant, it has been suggested that endophytic tumors have a higher propensity to metastasize to cervical lymph nodes than exophytic tumors.
ABSTRACT
@#BACKGROUND: The incidence of oral cancer is differed in the world. Oral cancer incidence was high in Melanesia, South-Central Asia, East and Central European countries,3 while it was likely to be low in Africa, East Asia, and Central American countries. METHODS: The study was carried out by retrospective method, by using the medical reports obtained from the National Cancer Center of Mongolia. This study, based on retrospective method was conducted from medical reports of 68 patients who were diagnosed with squamous cell carcinoma of the tongue and at the Department of Head and Neck Surgery, Radio and Chemotherapy of the National Cancer Center of Mongolia between 2005 and 2014. The data was analyzed using SPSS 20.0 software; descriptive and detailed statistical analysis was made. Assumptions were examined by H2 testing method; it shall be statistically significant when P value is less than 0,05. RESULTS: The median age of the 68 patients at diagnosis was 58 years (range=31-85 years) and were 57% (39) men, 43% (29) women with a male to female ratio of 1.3:1 The most common cancer sub-sites reported were lateral border (60%) Considering the composite stage of the disease, 25% patients were in early stages (I-8.8% and II-16.2%) whereas 75% were in advanced stages (III- 36.8%, IVA- 20.6%, IVB-17.6%). At the time of presentation, majority of the patients had T3 lesions 44.1%, followed by T1 in 11.8%, T2 in 29.4%, T4 in 14.7%. Regional lymph node involvement was present in 54.4% (N1-25%, N2-17.6%, N3-11.8%) Considering the correlation between tumor size and cervical lymph node metastasis was present in 25% of of T1 tumours, 45% of T2 tumours, 66.7% of T3 tumours 60% of T4 tumours. There was no correlation between the tumor size at the primary site (T-status), and the presence of lymphatic spread (N-status) p=0.357. CONCLUSION: Our study showed that oral tongue cancer is majority occur in fifth and sixth of life and with a male predominance. Tongue cancer had more occurred at the lateral border (60%) and majority of the incidence (75%) is in the advanced stages III or IV. Based on the data in this study, it is possible to conclude that health education and health promotion must be encouraged by public health policies in order to diagnose in early stage and reduce the incidence and mortality rates of tongue cancer.
