Background:However kidney transplantation has being performed in Mongolia since 2006, because of pre-transplant ensitization, ABO incompatibility, hepatitis B and C virus activation many patients are taken kidney transplantation in abroad. The transplantation centers use own immunosuppressive regimens.Objective:Our aim was to assess the immunosuppressive regimens efficacy and toxicity in kidney transplant Mongolian recipients.Material and Methods:We analyzed data from 96 adult kidney transplant recipients who had taken kidney transplantation in different transplant centers from August 2006 through January 2014. There were 3 kinds of regimens Group I Simulect induction with standard triple /FK506/CyA+MMF/AZA+steroid/, Group II Campath-1H induction with CNI monotherapy and Group III Campath-1H induction with standard triple /FK506/CyA+MMF/AZA+steroid/. We retrospectively collected the post-transplant first two year serum creatinine. The study was performed in 2014. The questionnaire was taken and blood samples collected for determination of tacrolimus through level and for other laboratory tests. The primary end point was the first two years serum creatinine, the secondary end points included rejection episodes, blood through level of tacrolimus and some laboratory findings.Results:The post-transplant first two years serum creatinine levels were significantly different in 3 groups. Group III showed similar results compared to Group I. There was not enough data of biopsy proven acute rejection episodes however group II said more rejections occurred. However participants said that rejection occurred in 15 (15.6%) biopsy was done only 3 (3.1%) cases. Blood through level of tacrolimus was significantly different in three groups. Some laboratory findings showed different between three groups.Conclusion:A regimen of Campath-1H induction with CNI monotherapy (Group II) may be advantageous for short-term renal function and cost effective but there were more rejection complications and increased creatinine. The regimen of Campath-1H induction with standard triple (Group III) may be advantageous for long-term renal function, allograft survival, but there should consider about infection complications and polycythemia. Simulect induction with standard triple could be best choice but transplantations were performed in experienced centers. The study enrolled few cases and cases which were performed at the beginning of transplant program so many things could influence on the result. The study was compared beginner transplant center with experienced centers. Longitudinal cohort study needed in the future.

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.

Introduction: Hepatocellular carcinoma(HCC) is the 6th most common cancer inthe world, but the first most commoncause of cancer death in Mongolia. Thereis no universally accepted consensuspractice guidelines for HCC owing to rapiddevelopments in new treatment modalities,the heterogeneous epidemiology and clinicalpresentation of HCC worldwide.Methods and Materials: This study wasconducted in the department of generalsurgery of Second Central Hospital ofMongolia between 2015 and 2016 on a totalof 36 patients with hepatocellular carcinoma.Results: The average of operationtime is a 132.2 min, the hospital stay 18.2days. Postoperative bleeding was 2.7% (1),encephalopathy 5.4% (2), wound infection5.4% (2), and incisional hernia 8.1% (3).There were not bile leak during 30 dayspostoperative day.Conclusion: Postoperative complicationis a comparable to different researcher.There were no death within first month.

Introduction: Health care workers of First Central Hospital of Mongolia have vaccinated with three different vaccines against SARS-CoV-2. We detected SARS-CoV-2 N and S-RBD antibodies after 30-90 days of second dose of vaccination. Method: Quantitation of antibodies to the spike protein of SARS-CoV-2 was performed for the detection of adaptive immune response in 291 HCWs vaccinated with Covishield, Sinopharm and Pfizer Biontech. Detection and quantitation of SARS-CoV-2 N and S antibodies were performed by the electrochemiluminesce assay Cobas e411, Roche. Result: SARS-CoV-2-S-RBD IgG titer were negative 0%, weak positive 0.4%, positive 17.5%, strong positive 82.1% of 246 HCWs vaccinated with Covishield and were negative 2.8%, weak positive 8.5%, positive 57.1%, strong positive 31.4% of 35 HCWs vaccinated with Sinopharm.
In all HCWs vaccinated with Pfizer Biontech SARS-CoV-2-S-RBD IgG titers were strong positive. Conclusion Humoral immunity was produced in HCWs after two doses of Covishield vaccine 100%, Sinopharm 97.0%, Pfizer Biontech 100% respectively. Antibody titer was higher among younger age workers.
