BACKGROUNDProstate cancer is the most frequent malignancy among men nowadays.METHODSImmunohistochemical expression of prostate-specific antigen (PSA) was retrospectively investigated in 10 patients admitted with clinical suspicion of the prostate cancer. Slides were collected from archived biopsiesandthey were stained for PSA.The final reaction product was evaluated as negative (0), weak/moderate positive (1), and intense positive (2).RESULTSGlandular prostate carcinoma was found in 40% (n=4) and undifferentiated carcinoma in 60% (n=6). The immunoreaction for PSA was intense positive in 30% (n=3), weak/moderate positive in 50% (n=5) and negative in 20% (n=2) of total cases.CONCLUSIONSWe concludethat PSA immunoreaction is helpful for the differential diagnosis based on our results.

In United States, person is diagnosed with blood cancer in every 3 minutes. In 2015, there were 1.665.540 total cancer cases and 9.4% of them lymphoma and leukemia . In 2015, there were 95 cases of lymphoma in Mongolia when compared 4 times increase to 2015 from 2010 . Bone marrow examination is an established diagnostic modality in the evaluation of various hematological disorders. BM examination can serve to establish or confirm a primary diagnosis of lymphoma or to determine the extent of disease dissemination for staging purposes. Biopsy is essential for diagnosis in a dry tap or blood tap which occurs when the marrow is fibrotic or densely cellular. Only a biopsy allows a complete assessment of marrow architecture and pattern of distribution of any abnormal infiltrates. In 2015.01-2016.01 fifty five bone marrow biopsies were retrieved from the files of the National First Clinical Hospital-Department of Hematology. These all statistical analysis was performed using by SPSS 17. Bone marrow processing and staining: The hematologist is instructed to place the freshly obtained BMTB specimens directly into buffer substance fixative and transport it immediately to the histopathology department, on the same day as the procedure.The next morning (after 20–24 h), the solution is decanted (with a strainer) and the biopsy specimen is washed in distilled water for 30 min. The biopsy specimens are left to decalcify for about 6 h before being processed and embedded in paraffin wax, with procedures similar as for other specimens.Sections, 1-mm thick (microtome set for 1 mm sections), are cut from the paraffin-wax blocks with the routine rotary microtomes in the laboratoryA total of 55 cases were reviewed from December 2014 to November 2015. The age of the subjects ranged from twenty two years to seventy eigth years with a male predominance (1.7:1). Data of 55 trephine biopsies were reviewed. The percentage of trephine biopsies in different length ranges was calculated. Twenty two biopsieswere of recommended length, i.e., ≥1.5 Cm while remaining 33 were less than the recommended length. The rate of positivity for diagnosis was 95.4% in group-1, 94.1% in group-2, 63.6% in group-3 and 40% in group-4 In all cases in our study 73% (n=40) were satisfactory and 27%(n=15) unsatisfactory slides .Our study showed that 40% trephan biopsies were of revommended length i.e >=1.5cm with 95.4% positive of diagnosis. However biopsies measuring 1-1.4 cm also had comparable result 94.1% .

IntroductionAfter discovering an important biological function of selenium, selenium content and its deficiency arestarted to be extensively studied in numerous epidemiological studies that have been conducted inmany countries in the world. In Mongolia, as a country geographically located in unstable climate zone,there are no studies conducted on selenium so far since the last century, except one study determiningselenium deficiency signs in livestock.GoalTo determine selenium (Se) content in Mongolian wheat and livestock meatMaterials and MethodsIn total 30 samples of wheat planted in Dornod, Uvs, Tuv and Selenge aimags of Mongolia and 142samples of Mongolian beef and beef imported to Russia from China, respectively were underwent inlaboratory analysis. Wheat was hold at room temperature to reach the regular weight, and muscletissue of meat was dried in a lofildryer. Dried wheat and meat were then powdered into homogenousconsistency and were kept in air proof polyethylene container at room temperature until being analyzed.Selenium content was determined by fluorometric method [2].ResultsOut of wheat sorts grown in Mongolia, selenium was detected in extremely low level in wheat of Khalkhingol sort of Dornod aimag (7±1 mkg/kg) and Selenge sort of Selenge aimag (8±1 mkg/kg), and in wheatsold in retail outlets of Baruunturuun soum of Uvs aimag (7±1 mkg/kg) and Khongor soum of Darkhan-Uul aimag (8±1 mkg/kg). However, selenium content was relatively higher in wheat samples of Darkhan34 sort of Baruunturuun soum of Uvs aimag (31±5 mkg/kg) and of Altaiskaya sort of Jargalant (29±3mkg/kg) and Bornuur (32±1 mkg/kg) soums of Tuv aimag, and in sample of retail wheat of Sagil soum(29±1 mkg/kg) of Uvs aimag.When determined the selenium content in Mongolian livestock meat, in average, the selenium contentwere 109-296 mg/kg in beef, 94-200 mg/kg in lamb, 120-225 mg/kg in horse meat and 124-197 mg/kg ingoat, and the differences were not statistically significant (p>0.5). The highest selenium content of 400mg/kg was detected in horse meat of Govi-Altai aimag.Conclusion: The selenium content in wheat and livestock meat which are the mean stable food forMongolians is considerably low.

IntroductionMongolian rural population lack of access to adequate health services due to the fact that they live remotefrom urban hospitals. With the rapid spread of telemedicine in most countries, has been promoted as apromising tool to address deficiencies in delivering health care in developing countries.In late 2008 the Swiss Surgical Team (SST) started the telemedicine project MonTelNet in Mongolia incollaboration and with financial support of the Swiss Agency for Development and Cooperation (SDC).GoalThis study aims at evaluating the diagnostic accuracy of such a service by reviewing 212 telepathologydiagnoses delivered to the local experts in Ulaanbaatar between January 2009 and June 2013.Materials and MethodsUnder the MonTelNet project all province (Aimag) hospitals were equipped with hardware necessaryfor practicing telemedicine, in particular with computers with digitalized microscopes and cameras. Thesoftware CampusMedicus® (CM) was developed together with Klughammer GmbH. Software and alldata and comments exchanged over the MonTelNet are stored on a central server. Each of the originaldiagnoses issued through the CM telepathology (TP) server was compared to an independent reviewdiagnosis based on the original glass slides.RESULT For 188 specimens (89.9%) the TP diagnosis were completely identical with the review diagnosison the original glass slide. 12 specimens (5.7%) showed minor discrepancies (clinically identical) and 5specimens (2.4%) showed moderate discrepancies which were not clinically relevant. four cases (1.9%)exhibited a marked discrepancy (clinically relevant) between the TP diagnosis and the review diagnosis.Three specimens were classified as “other”.DISCUSSION The results of the study show a very high accuracy of the TP diagnosis provided. The TPdiagnoses differed markedly from the review diagnoses based on the original glass slide in only 1.9%of the 212 cases. 89.9% of all cases showed complete concordance between TP and review. Thesefigures are comparable to figures from other evaluations of static image telepathology.Conclusion:1. The results of the study show a very high accuracy (94.7%) of the TP diagnosis provided. TheTP diagnoses 89.9% of all cases showed complete concordance between TP and conventionalreview.2. Problem with image selection show a different picture and occur more often in cases with markeddiscrepancies between TP and review - χ2-test shows significant correlation (p<0.001).

BACKGROUND. As of 2015 39,1% of all new cancer cases in Mongolia were HCC having
the highest prevalence and it has increased by 4% to the previous year. (Health indicator
– 2015, CHD). Although there are quite a lot researches have been done on general
cause and impacting factors of HCC, the relevance between the mechanism leading
to eventual cancer and the risk factors is still unknown yet. PURPOSE: To define the relevance
of the beta-catenin and P53 expression in HCC with the risk factors of HCC in
Mongolia. RESULT: 1. 50% of HCV infection in men is related with alcohol consumption
and 40% alcohol combined with tobacco consumption. HBV infection has relevance of
46% with tobacco and 52,8% with alcohol consumption. 2. In the first phase of research
in 21 HCC cases beta-catenin was identified in cell nucleus and cytoplasm after immunohistochemistry.
CONCLUSION: 1. It was to observe that HCV infection is commonly
combined with alcohol consumption in HCC cases. 2. Although beta-catenin expression
was high in HCV, HBV infection and alcohol high risk group, the P53 expression was
high among alcohol high risk group. Р < 0.05

IntroductionThe trace elements selenium is a constituent of the antioxidant enzyme glutathione peroxidase. Becauseit boosts the body’s antioxidant capacity, selenium is thought to have some ability to control cell damagethat may lead to cancer. Selenium low status has been linked to increased risk of various diseases, suchas cancer and heart disease.GoalInvestigate serum selenium level of adult mongolians and conduct age and gender coparartive analysisof the serum selenium content.Materials and MethodsCross sectional study was performed among the 2339 apparently healthy Mongolians of both gendersaged ≥18 years. In the study were used questionnaire and biochemical methods. Blood samples werecollected from all subjects and serum selenium concentration was measured by atomic absorptionspectrophotometry method using thermo fisher scientific analyzer.ResultsThe mean and confidence interval of serum selenium level in adult Mongolians was 0.78 μmol/l (95%CI0.77-0.79) and there was no significant difference between genders. Thus the mean was 0.77 μmol/l(95%CI 0.76-0.80) among women and in men it was 0.78 μmol/l (95%CI 0.76-0.80). Data analysisrevealed that older age group individuals were at risk of lowered serum selenium level. In particular,the oldest age group of over 60 years (females: 0.74 μmol/l, 95%CI 0.70-0.77; males: 0.68 μmol/l,95%CI 0.64-0.71). The difference in selenium status between age groups was statistically significant inboth sexes. The overall prevalence of serum selenium concentrations indicative risk of deficiency was59.7%, with no significant differences in the prevalence by genders. Survey findings revealed that riskof selenium deficiency had statistically significant difference between age groups among the surveyedmen.Conclusion: The mean value of serum selenium in adult Mongolians was 0.78 μmol/l and there was nosignificant difference between genders.

BACKGROUND: According to WHO, Non-communicable disease take place 43% of morbidity as well as 63% of mortality in worldwide and it will may increased as 60% of morbidity, 73% of mortality in 2020. Therefore one quarter of NCD associated with composition and usage of foods. Obesity and Diabetes mellitus are caused by accumulating saturated fat in body due to excessive use of high calorie. High-fat diet promotes lipid deposition in solid organs including skeletal muscle which is underlying cause of insulin resistance.
METHODS: Same aged, Inbred (C57BL/6J) 20 male mice are involved in this study. They are raised and fed in central core laboratory of MNUMS. Feeding of mice “Beijing Branch of the Joint Feed Co LTD” from Republic of China produces forage for laboratory animals. They were divided into two groups. A control group mice had been fed standard chow while experimental group mice had been fed 45% high fat diet for 4 weeks. The morphological effect of the a high fat diet was examined by light microscopy.
RESULTS: Liver of experimental mice was seen pale and parenchyma had a fatty changes compared to control group liver in gross anatomy. Periportal necrosis and lipid droplet deposition in hepatocytes of study group were detected as microscopically. There is fatty accumulation between solid tissue of pancreas and islets of Langerhans get smaller in study group. Experimental mice which were fed by 45% of fat containing food had lipid droplets were observed in fibers. Therefore degenerated fibers showing separation from the basement membrane and acidophilic staining were observed in skeletal muscle.

Nutrition is a key factor in the normal functioning of the immune system, and malnutrition is one of
the most common causes of immunodeficiency worldwide today. However, the public health policies
on immune system and infection lacks the nutritional strategy to ensure the optimal functioning of
the immune system Loss of cellular immunity, phagocyte function, blood protein complex, cytokine
synthesis, and A-immunoglobulin secretion are generally associated with protein-energy deficiency.
Some vitamins and minerals, such as A, B6, B12, C, D, E, folic acid, zinc, iron, selenium, magnesium,
and copper, plays an important role in the immune system function. Deficiency or low levels of
micronutrients can negatively affect the immune system and reduce the ability to fight infections.

Background:
The correlation between hepatitis B, C viruses (HBV, HCV) and B cell non-Hodgkin’s Lymphoma
(B-NHL) and reducing mortality have been studied extensively worldwide
Objective:
In this study, we aimed to determine the prevalence of HBsAg and anti-HCV positive cases among
B-NHL patients and its influence on the survival rate of these patients (on ≤12 months).
Materials and Methods:
We have done a retrospective analysis on patients who aged over 20 years and newly diagnosed at
the Hematology Center of the First State Hospital between 2015-2018. The patients’ information was
collected according the study ethics. We divided the patients into 2 groups, survival rate less than
12 months (≤12 months) and survival rate more than 13 months (≥13 months), and compared them
regarding age, gender, seroprevalence, and Ann-Arbor stage.
Results:
Overall, 226 patients (107 males and 119 females with average 54.4) were enrolled in the study.
There were 15% HBsAg positive and 41,6% anti-HCV positive cases, while Baatarkhuu et al. (2005)
reported (11.8%, 15.6%; p=0.160, p<0.00001) and Bekhbold et al. (2013) reported (11.1%, 10.6%;
p=0.055, p<0.00001) in apparently healthy population. Moreover, anti-HCV positive cases among
B-NHL patients were higher (p<0.00001) than those (27%) among hepatocellular carcinoma (HCC)
patients and same (p=0.404) with those (39%) among liver cirrhosis patients in Mongolia (Bolormaa
et al., 2009). Furthermore, 72.0% of all subjects in III-IV stages was accounted for HBsAg, anti-HCV
positive group which had ≤12 months, while 52.1% of them was accounted for HBsAg, anti-HCV
positive group which had ≥13 months and was statistical significantly lower (p=0.02).
Conclusion
Anti-HCV and HBsAg positive cases might contribute to survival rate with the B-NHL patients
diagnosed at the III-IV stages. HCV prevalence among B-NHL subjects was significantly higher than
that among the general population prevalence and was same with anti-HCV positive prevalence
among the HCC.
