Introduction:When a central nervous system disorder (meningitis, encephalitis, hemorrhage, leukemia infltration and other neoplasma) is present, cerebrospinal fluid (CSF) shows various changes that reflected the condition. Therefore it is essential to test CSF. Different types of CSF tests include cell count; cell differentiation; chemistry; immunology; microbiology and molecular biology. CSF cell count and cell differentiation in particular, are crucial in differentiating diagnosing various CNS disorder needing immediate care and in evaluating the treatment. The patient’s prognosis largely depends on how accurate diagnosis was done and how early treatment was provided. There for CSF test require high precision and accuracy. In Mongolia until now 2st and 3st level hospital using manual method for CSF cell count and cell differentiation test. In this test has 2 actual problems, which is depends on the analytical techniques, skills and sample stability specific problem. But in Japan in 2011 newly designed Sysmex XN Series hematology analyser with body fluid mode (CSF,pleural effusion, peritoneal and synovial fluid). On The First Central Hospital of Mongolia In 2013 frst timeinstalled Sysmex XN-2000 hematology analyser andpossible use of body fluid automatic testing methods.Materials and methods:We evaluated the basic assay performance of the body fluid mode on the automated hematology analyzer XN-2000, which is used for analysis of CSF fluid. We compared between the manual method and XN-2000 analysis for nucleated (WBC), mononuclear (MN) and polymorphonuclear (PMN) cells was also randomly studied using 10 CSF samples of inpatient section our hospital.Results:In CSF samples the coeffcient correlation(r) for WBC/µl, MN%, PMN% were respectively 0.83, 0.95 ба 0.95.Discussion:The correlation for MN%, PMN% were between automate and manual method was good, that is similar to the other researchers. Whereas the correlation for WBC/µl slightly low, this was probably correlation relatively weak or show discrepancies. In introduction inscriptive in analysis accuracy can to affect analytical techniques skills, sample stability and specifc many problems. Therefore scientifc studied and proven ability specifcity, sensitivity, reproducibility, quality, personnel low cost and spend less time, automatically Sysmex XN series hematology analyzer is desirable to domesticate an appropriate level of medical laboratories.

Objectives: The purpose of our study is to examine characteristics of body composition and anthropometric measurements in older Mongolian adults. Methods: This cross-sectional study included 268 individuals aged 45 years and older who visited national hospitals over a period of one month. Body weight, BMI, waist circumference (WC) and other body circumferences, and body composition (body fat percentages, fat-free mass index, skeletal mass index) were measured and the Short Physical Performance Battery (SPPB) score was used to test the physical performance. Results: The sample was composed of 73.7% women and 26.3% men, and the mean age was 58.1±8.9. All measurements were relatively higher than the normal range in older Mongolian adults. Obesity in women was relatively higher than men. 77.1% of all participants were obese according to BMI, 92.5% were obese according to body fat percentage, and 96.2% were centrally obese according to WC. Among people aged 45-64 years, prevalence of obesity increased and then decreased in ages 65-74 years. Age was significantly correlated with WC and the SPPB score was indirectly correlated with age (p<0.05). Conclusion: Obesity in older Mongolian adults is comparatively higher for women and tends to increase with age.
