Osteoporosis and the fractures associated with it constitute a major public health concern. Osteoporosis is a systemic skeletal disease characterized by low bone density and microarchitectural deterioration of bone tissue with a consequent increase in bone fragility. A WHO Scientific Group on April 2000 estimated osteoporosis is well-defined disease that affects more than 75 million people in Europe, Japan and the USA, and causes more than 2.3 million fractures annually in Europe and the USA.In Europe, for example, the number of women over 50 years of age is projected to increase by 30%-40% between 1990 and 2025.Most studies suggest the required daily intake is between 1000 mg and 1500 mg in postmenopausal women not taking estrogen replacement therapy. This can be obtained from about three serves of dairy products per day. For example, one glass (250 mL) of milk, two slices (40 g) of Cheddar cheese, or one tub (200 g) of yoghurt each contains about 300 mg of calcium. In one French study involving vitamin D deficient institutionalized elderly patients, simple vitamin D3 (800 IU) and calcium (1200 mg/day) reduced hip fractures by 43%.The management of postmenopausal osteoporosis should be based on an individual risk/benefit analysis, time since menopause, presence or absence of estrogen with drawal symptoms, history of atraumatic fractures, and other medical conditions. Socioeconomic evaluation of osteoporosis can be undertaken to estimate the cost of disease, the effectiveness of treatments, and the effects of strategies to identify patients at high risk such as screening and case-finding, or to assess global strategies. Global strategies aimed at increasing the BMD of the general population have not been adequately tested, but general advice on lifestyle is an important component of patient care.

The persistent high-risk human papilloma virus(HPV) infection is a necessary cause for developing cervical carcinoma. Although carcinogenic HPV types are found in virtually all invasive cancer, with types 16 and 18 being found in approximately 70 percent of cases. High risk HPV types’ Е6 and Е7 oncogenes have a pivotal role in cervical carcinogenesis. The p16, the cyclin-dependent kinase inhibitor and p16 overexpression in cervical neoplasia is a surrogate marker of high risk HPV E7 mediated pRb catabolism reflecting disruption of mechanisms that control cell proliferation and indicating persistent infection with high risk of development of neoplasia.Thus in worldwide p16 had been identified as the novel biomarker in pre-invasive cervical lesions. Objective: For the purpose to detect for cervical cancer risks we examined HPV16/18 and cell cycle protein p16 expression in cervical lesions.A total of 96 specimens enrolled in this study and 50 were diagnosed as LSIL and 46 were diagnosed as a HSIL. To detect HPV16/18 and p16 in cervical lesions used immunohistochemistry. Statistical analysis was performed using SPSS 16.0. Descriptive analysis was performed by Chi- Square test and also determined sensitivity and specificity.Positive stainingfor p16 and HPV16/18 were observed whole cell, within both the nuclear and cytoplasmic subcellular regions by immunohistochemistry. 63% of specimens had only HPV16 infection and 22% of specimens had only HPV18 infection.Also 14% specimens had co-infection with two viral types and 28% specimens had not above two most HPV infection. There were a significant difference for HPV16 positivity (X2 = 4.93, P < 0.05) and were not significant difference for HPV18 positivity (X2 = 0.28, P > 0.05) in HSIL and LSIL groups. There were not a difference for p16 in HSIL and LSIL groups.(X2 = 0.23, P > 0.05), respectively.P16, yielding a diagnostic sensitivity for HPV 16/18 were 82% and 30%, specificity for HPV 16/18 were 40% and 80%, respectively. In conclusion it is possible to detect high risk HPV types and persistent infection by immunohistochemistry in cervical intraepithelial squamous cell lesions. There is still critical need to use HPV testing and other molecular surrogate markers of HPV such as p16 in primary screening program.

IntroductionMany factors can contribute to the occurrence of COPD. Recent studies have pointed to the notion thatpolymorphism of candidate genes may also play a signifi cant role in COPD pathogenesis.GoalTo investigate the association of polymorphisms in ADRB2 and TNF-α genes with COPD.Materials and MethodsWe genotyped three SNPs included rs1042713 and rs1042714 in ADRB2, rs1800629 in TNF-α gene,using PCR-RFLP method.ResultsThere is no statistically signifi cant difference was observed for TNF-α rs1800629 between case andcontrol groups. Genotype frequency of the homozygote Gly16 (rs1042713) was more frequent in COPDpatients than controls (OR=3.25; 95%CI, 1.58–6.66, p=0.0037). Also, haplotype frequency of Gly/Gly16+Gln/Glu27 was signifi cant difference among cases and controls (OR=5.03; 95%CI, 1.8–14.2,p<0.01).Conclusion:Overall, ADRB2 rs1042713 and rs1042714 polymorphisms are associated with increased susceptibilityto the development of COPD. Further studies in large groups of patients with COPD are needed toaddress other genetic risk factors.

Background:The evidence that some strains of Lactobacillus and Bifidobacteriumare able to inhibit H.pylori growth through the release of bacteriocinsor organic acids. Therefore, it is important to in vitro study develop low-cost, large-scale, alternative probiotic to the at-risk population to prevent or decrease H. pyloricolonization.Methods:18 samples of gastric biopsies were cultured according to standard microbiological proceduresand were grown under microaerophilic conditions on selective Pylori agar. An in vitro disk diffusion assay was employed to assess the lactic acid bacteria LBO1, 2, 3, 4, 6, 7 cells and cell free supernatants (CFS) and bifidobacteria BFO1, BFO4 anti-H.pylori activity.Results: Ability of LBO1 strain to inhibit growth of H.pylori is 55,5% [95% CI 32.5-78.4], LBO-2 88,8% [95% CI 74.2-103.3], LBO-3 50%[95% CI 26.9-73.0]and LBO-4 38,8% [95% CI 32.5-78.4]. Then LBO 6 and LBO7 strains had no inhibitory activity against H.pylori. Average inhibition zone is 8-14mm (11,6 mm) for LBO1 strain, 10-16mm (11.3mm) for LBO2 strain , 8-12mm (10,2mm) for LBO3 strain and 10-12mm (10,5mm) for LBO4 strain.Inhibitioryactivity of Lactobacillus LBO1 supernatant against H.pylori accounts for 61.1% (n=11), LBO2 supernatant for 72,2% (n=13), and LBO3 supernatant for 33,3% (n=6) , while LBO4 supernatant inhibits only HP78 strain. LBO6 and LBO7 supernatants were both Lactobacillus LBO cultures. Average inhibition zone is 8-12mm (10 mm) for LBO1 supernatant, 10-16mm (11.3mm) for LBO2 supernatant , and 10-12mm (10,3 mm) for LBO3 supernatant.Bifidobacterium BFO1 strain was 83.3% inhibition activity. But BFO4 was not inhibit against all H.pylori strains.Conclusion:Lactobacillus LBO2 and Bifidobacterium BFO1 strains were isolatedfrom Mongoliantraditional fermented milk product were obtained more inhibition against H.pylori strains other LactobacillusLBO and Bifidobacterium BFO strains.

INTRODUCTION: Urinary tract infections among the most common bacterial infectious diseases encountered at all ages. Escherichia coli are being the etiologic agent in 50–80%. Therefore, it is an important public health problem. E.coli causing urinary tract infections express pilli, fimbriae and others adherence virulence factors. GOAL: To detect the some adherence virulence factors of Uropathogenic Escherichia coli (UPEC) in Ulaanbaatar, Mongolia MATERIALS AND METHODS: A total of 76E.colisampleswere collected. These samples were positive bacteriological examination of urine, performed at the bacteriological laboratory of the State Central Third Hospital and State Central First Hospital, Ulaanbaatar, Mongolia. The biofilm formation was evaluated by the growth rate of E.coli on plastic surface.The detection of the virulence factors type 1 fimbriae (fimA gene) and P-fimbriae (papC) was performed by multiplex PCR using gene specific primers.Curli expression was determined by using congo red agar. RESULTS: The evaluation of bacterial biofilm formation using 96 well plates showed 40 negative (52.6%), 32 weak biofilm (42.1%) and 4 moderate biofilm (5.3%) formation for E.coli and no strong biofilm forming strain was detected. The cell surface protein (curli) was detected by Congo red agar. The result was 71% positive for studied E.coli strains. The detection result of pili genes by multiplex PCR showed that fimH gene detected for 73 (96.1%) and papC gene detected for 18 (23.7%) E.coli cultures. CONCLUSION: Almost half of surveyed Uropathogenic E.coli isolated in Ulaanbaatar, Mongolia had ability of biofilm formation and it has been determined by the bacterial surface protein (curli), which is one of bacterial adherence factors, may cause biofilm formation.

Introduction: Enteroaggregative Escherichia coli (EAEC) is an important agent of acute and persistent diarrhea worldwide. Few cases have been reported in healthy children. EAEC strains are characterized by aggregative adherence (AA) to HEp-2 cells, wherein bacteria are seen in “stacked brick” aggregates attaching to HEp-2 cells and usually to the glass surface between cells. Goal: To identify Enteroaggregative Escherihia coli using multiplex polymerase chain reaction (PCR) and HEp-2 adherence assay in Ulaanbaatar, Mongolia Materials and Methods: A total of 329 E. coli strains were isolated from stool with diarrhea in National Center for Communicable Diseases from July 2012 through September 2014. All specimens were processed by routine microbiological and biochemical tests in the bacteriological laboratories to identify Salmonella spp., Shigella spp. All specimens in our study were negative for these bacterial and parasitic pathogens. The biofilm formation was evaluated by the growth rate of E.coli on plastic surface. PCR assays were used to detect genes of five types of diarrheagenic E.coli (DEC). All of the DEC strains showed mannose-resistant adherence to HEp-2 cells, and aggregative adherence was predominant in these isolates. Bacterial susceptibility to antimicrobial agents determined by the Kirby Bauer disk diffusion method on Muller Hinton agar. Results: EAEC (31.9%) was the most prevalent by PCR and HEp-2 assay comparing with others. EAEC by multiplex PCR in samples (11, 3.3%), followed by enteropathogenic E.coli (EPEC) seen in 2.1%. Enterohemorrhagic E.coli (EHEC) and enteroinvasive E.coli (EIEC) were found in 7 (2.1%) and 1 (0.3%) of the samples. Enterotoxigenic E.coli (ETEC) and diffusely adhering E.coli were detected in 2 (0.6%), respectively. The evaluation of bacterial biofilm formation using 96 well plates showed 309 negative (93%), 15 weak biofilm (4.6%) and 8 moderate biofilm (2.4%) formation for E.coli and no strong biofilm forming strain was detected. Above 50% of antibiotic resistance was observed for ampicillin, trimethoprim/sulfamethoxazole, cefuroxime and cephalotin. Also, 95.4% of isolates were resistant to at least three different classes of antimicrobial agents and considered as multidrug resistance. Conclusion: EAEC is most prevalent pathogen among DEC in our samples. It is necessary to implement EAEC identifying method on Hep-2 assay in our laboratory practice.

Introduction: PCR to detect and amplificate the virulence genes of STEC is specific and more sensitive, however, it takes five to six hours for whole test procedure and requires special lab instruments such as thermocycler. Loop-mediated isothermal amplification is a simple, rapid, specific and cost-effective nucleic acid amplification method by using four to six primers when compared to PCR, nucleic acid sequence-based amplification, self-sustained sequence replication and strand displacement amplification. Materials and Methods: In our study, we analyzed comparison of PCR and LAMP results on standard strain used quality control strain solution which diluted 1pg/µL DNA, 10 pg/µL DNA, 100 pg/µL DNA, 1 ng/μL DNA, 10 ng/μL DNA, and 100 ng/μL DNA concentration from LB agar cultures. Research ethics: Permission to submit the survey was granted by the Ethics Review Committee of the MNUMS and the survey was conducted in accordance with the rules and regulations. Goal: Detection and comparison of STEC by PCR and LAMP Result: Sensitivity of Stx1 and stx2 genes in PCR results are positive in 10 pg/µL DNA solution and negative in 1pg/µL DNA. In LAMP test results showed that positive for all concentration. It shows that LAMP method sensitivity is 10 times more than PCR. Conclusion It shows that LAMP method sensitivity is 10 times more than PCR. All in allLAMP test is cost effective test with sensitive for detection STEC.

Cervical cancer is commonly caused by infection with human papilloma virus(HPV) and some risk factors are involved in the etiology of it.1 All over the world 437000 people are diagnosed with cervical disorders and half of them die due to cervical cancer.2 Annually 12000 new cases of cervical cancer are detected and 5000 women die because of it. In Spain about 2000 women are determined in the 3rd and 4th stage of the disease per year.3 Over the period 2000-2008 cervical cancer rate is 8 %among all cancers in Mongolia. Approximately 16 % of women’s cancer is cervical cancer. 4 In developing nations prevalence rate of cervical cancer is higher because of malnutrition, quality and framework for early detection are not satisfying and some reproductive risk factors also influence on it. 5 Worldwide diagnosing early and rapid management of precancerous condition and cervical abnormalities turn into main issue. Therefore based on these detection of premalignant lesion of cervix by colposcopy the main objective of the study. The overall goal of the study is to detect the premalignant lesion of cervix by colposcopy and determine of some risk factors and study the results.A total of 71 women, who are treated in Women’s inflammatory disease unit, Infertility and Women’s endocrine disorder unit are recruited for the cross sectional study. The women, who conducted the study were selected by accidently and colposcopy was done. They also have completed special questionnaires. The data were analyzed using the SPSS 19.0, Windows Office. The average age of the women was 38±9.4. Colposcopy was done 90.1% (n=64) of women, 9.9% (n=7) of women had not colposcopy. Among the women who had colposcopy, biopsies were taken 56.3% (n=36). During colposcopy we analyzed condition of cervix then we took biopsy from suspected areas and sent it histology laboratory. We compared predictive diagnosis, histology results after colposcopy and 33.3% (n=12) were identified as normal, CIN I was 52.7%, (n=19), CIN II was 5.5% (n=2), CINIII was 2.7% (n=1), cervical cancer is confirmed in 5.5% (n=2). We studied risk factors that can influence the cervical disorders among the women recruited in the study and age of first sexual intercourse (r=0.356, p=0.033), number of abortion (r=0.412, p=0.029) were statistically significant. However age of the women, parity, usage of contraceptive pills, smoking, number of sexual partners were statistically not significant.(p>0.05) When women’s age of first sexual intercourse is younger, cervical cancer disorder occurs30% greater comparing to women having first sexual intercourse later, (p<0.05, R=0.3), when number of abortion increases cervical cancer disorder increases 40%(p<0.05, R=0.41).

IndroductionThe short tandem repeats (STR) are rich source of highly polymorphic markers in the human genome. In this study, we used a commercially available multiplex STR typing kit to study 15 STR systems (D3S1358, THO1, D21S11, D18S51, Penta E, D5S818, D13S317, D7S820, D16S539, CSF1PO, Penta D, vWA, D8S1179, TPOX and FGA,) in the Mongolians population, and estimated the allele and genotype frequencies. These 15 STR loci include 2 new pentanucleotide repeat STR loci, Penta E and Penta D, so are not studied in Mongolians.GoalTo determine allele frequency of STR loci D3S1358, THO1,D21S11, D18S51, D5S818, D13S317, D7S820, D16S539, CSF1PO, vWA, D8S1179, TPOX, FGA Penta E, Penta D in Mongolian population.Materials and MethodsThe liquid blood, blood stain and saliva samples were taken from 165 unrelated individuals from Mongolian. Extraction DNA: Genomic DNA was extracted from whole blood samples by the standard method of phenol-chloroform-isoamyl alcohol and Wizard Genomic DNA Purification kit, Promega Corporation [21], from blood stain and saliva samples QIAamp DNA micro kit, Qiagen [25], AccuPrep Genomic DNA Extration kit, Bioneer, Koreans extraction method respectively.PCR: PCR amplification was performed using 10-15 ng genomic DNA template according to manufacturer’s protocol (PowerPlex® 16 and PowerPlex® 16HS kit, Promega Corporation, USA). Typing: DNA typing was performed on the ABI Prism 310 Genetic Analyzer (Applied Biosystems) using the recommended protocol. The results were analyzed by Data Collection (Version 1.1), GeneScan (Version 3.1), and Genotyper (Version 3.1) softwares (AppliedBiosystems).ResultsWe assessed forensic and population genetic studies using 15 STR loci included in s sample of 165 unrelated individuals from Mongolian. Allele frequency were listed in Table 2. Totally 20 alleles /5, 7-25/ were found from microsatellite Penta E locus and allele 11 has most frequent (0.1128). 6-16 alleles were found from Penta D locus and allele 9 has most frequent (0.3262). This result is interesting because allele 6 of Penta D locus was found rarely among other populations. But relatively higher frequency of allele 6 (0.0183) was found in Mongolian population. A population comparison based in genetic distance and genetic diversity calculated from allele frequencies of the 15 STR loci from obtained five different populations is shown the Table 3. Conclusions:1. Penta E locus was highly polymorphic, and 20 alleles were found in this Mongolians population and allele 11 was most frequent.2. Penta D locus was 20 alleles were found in this Mongolians population and allele 9 was most frequent.

Bacground: DST by conventional methods takes several weeks, while early diagnosis of the disease and the rapid identification of resistant strains are essential for efficient treatment and control of the MDR strains. Rapid molecular testing of detecting MDR-TB is needed.Objective: The aim of this study was to assess performance of molecular line probe assay, Genotype16 MTBDRp/us, for rapid detection of RIF and INH resistance for M.Tuberculosis in Mongolia. The sensitivity and specificity of Genotype® MTBDRp/us to detect RIF and INH resistance-associated mutations in culture specimens and directly in smear-positive clinical specimens was examined and compared with conventional culture and drug susceptibility testing on solid medium.Material and Methods: The subjects of this study were 218 MDR-TB suspects aged 14-75 years from 8 districts in Ulaanbaatar city. The study was conducted from July 2009 to May 2010. The Genotype M. Tuberculosis drug resistance first line (MTBDR plus) assay (Hain Life-science, Nehren, Germany) was tested on directly on 41 sputum specimens and 109 clinical isolates.Results: The high correlation of the results from Genotype® MTBDRp/us and conventional drug susceptibility testing was obtained from this study. The results clearly show high performance of Genotype® MTBDRp/us with almost 100% accuracy for all the important indicators, such as sensitivity, specificity, positive and negative predictive values of detection of RIF and INH resistance. Some minor discrepancies were obtained in comparison with DNA sequencing results.Our study found that among high proportion for detection of RIF resistance, S531L mutation (MUT3 band) occurred the most commonly, with 80.0% of all RIF-resistant strains (83.6% of MDR) having the mutation. Other mutation in the 530-533 regions was common, as detected by the lack of binding to the WT8 probe in the absence of S531L mutation.In this study we observed that mutations in the promoter region of inhA gene played a major role (67.6 % (63.9% of MDR strains and 90% of INH-mono-resistant strains) had a mutation in the inhA.Conclusion: The Genotype® MTBDRp/us assay was demonstrated as a rapid, reliable and highly accurate tool for early detection of MDR-TB through examining smear positive cases enabling early start of appropriate therapeutic and public health measures to control of the spread of drug resistant M.tuberculosis in the population.
