  • The water soluble redox polymer, poly(N-vinylimidazole) complexed with Os(4,4'-dichloro-2,2'-bipyridine)$_2Cl]^+$ (PVI-[Os(dCl-bpy)$_2Cl]^+$), was electrodeposited on the surface of a glassy carbon electrode by applying cycles of alternating square wave potentials between 0.2 V (2 s) and 0.7 V (2 s) to the electrode in a solution containing the redox polymer. The coordinating anionic ligand, $Cl^-$ of the osmium complex, became labile in the reduced state of the complex and was substituted by the imidazole of the PVI chain. The ligand substitution reactions resulted in crosslinking between the PVI chains, which made the redox polymer water insoluble and caused it to be deposited on the electrode surface. The deposited film was still electrically conducting and the continuous electrodeposition of the redox polymer was possible. When cycles of square wave potentials were applied to the electrode in a solution of bilirubin oxidase and the redox polymer, the enzyme was co-electrodeposited with the redox polymer, because the enzymes could be bound to the metal complexes through the ligand exchange reactions. The electrode with the film of the PVI-[Os(dCl-bpy)$_2Cl]^+$ redox polymer and the co-electrodeposited bilirubin oxidase was employed for the reduction of $O_2$ and a large increase of the currents was observed due to the electrocatalytic $O_2$ reduction with a half wave potential at 0.42 V vs. Ag/AgCl.

  • 전신마취를 필요로 하는 무증상 HBsAg양성 간효소치가 증가된 환자 11명을 대상으로 enflurane으로 마취한후 술전, 술후 3일, 7일 및 10일에 간기능검사를 실시하여 그 변화를 비교 검사한 결과 다음과 같은 결론을 얻었다. 1) SGOT, SGPT SGOT, SGPT는 술후 3일에는 술전수치보다 약간 증가하였으나 7일, 10일에는 현저한 증가를 보였다. 8예에 있어서는 술후 3일에 술전치 보다 약간 증가한 양상을 보였고 7일, 10일에 술전치와 비슷하게 되었으나 3예에서는 3일에 SGOT, SGPT가 약간 증가하더니 7일, 10일에는 SGOT, SGPT가 300-500IU로 상당히 증가하여 간염치료를 하여 술후 2개월후에 술전치와 비슷하게 하강하였다. 2) Alkaline phosphatase, total protein, albumin, total bilirubin, and direct bilirubin은 술후 3일에 정상범위를 벗어난 변화를 보였으며 7일부터 정상범위내로 회복되었다. 이상의 결과를 보아 enflurane마취가 간기능에 큰 영향을 미치지 않는다고는 하나 HBaAg양성 간효소치가 증가한 환자에게는 마취시 간염으로 이행될 가능성이 높으므로 상당히 조심을 하여 마취를 시행하여야 할 것으로 사료된다.

  • Background: Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening disease. Despite of proper treatment and improving treatment regimens, HLH patients still show a fatal prognosis. Therefore the evaluation of prognostic factor is important and there are many studies about hyperbilirubinemia as a prognostic factor in HLH. So we studied the prognostic value of hyperbilirubinemia in HLH children. Methods: A retrospective analysis was performed about 33 patients who were diagnosed with HLH at Pusan National University Hospital and Yangsan Pusan University Hospital between January 2000 to December 2012. We reviewed the clinical characteristics, laboratory findings, and results of treatment to identify hyper-bilirubinemia as a prognostic factor in HLH patients. Results: The median age of patients at diagnosis was 32 months. Most of patients presented with fever, pale appearance, abdominal pain and jaundice. Forty-eight point five percentage of patients showed normal serum bilirubiln level (<2.0 mg/dL) and 51.5% showed hyperbilirubinemia (${\geq}2.0mg/dL$). In normal serum bilirubin group, 1 patient (6.3%) was relapsed and 1 patient (5.9%) was relapsed in hyperbilirubinemia group. In the hyperbilirubinemia group, the mortality was higher than the normal bilirubin group but, there was no statistical significance. Conclusion: As a prognostic factor serum bilirubin at diagnosis in HLH patients, there was no significant correlation between hyperbilirubinemia and poor outcome. But, our study has a limitation that the number of patients is too small and almost showed good prognosis.

  • The purpose of this study was to evaluate the changes of liver function test before and after treatment in patients admitted to Korean medicine hospital. We checked liver function test level (aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, total bilirubin, direct bilirubin) of 147 patient who admitted in Korean medicine hospital from July 1, 2015 to June 30, 2018. The subjects were selected those who took herbal medicine continuously during the admission period and who performed liver function test on admission and before discharge. And the subjects were excluded those who had a history of liver and biliary disease at the time of admission or who took hepatoprotectants. Aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase significantly decreased compared with the values of admission(p<0.05), but total bilirubin and direct bilirubin were not significantly changed(p>0.05). On admission 31 patients(21.1%) had abnormal liver function and 6 patients(4.1%) had liver injury while 19 patients(12.9%) had abnormal liver function and 6 patients(4.1%) showed liver injury before discharge. This study suggests that herbal medicine may not injure liver function.

  • Purpose: The aims of this study was to compare and evaluate the clinical characteristics, laboratory data, and prognosis for infants under age 1 year with CMV hepatitis and those with viral hepatitis of unknown etiology. Methods: A retrospective study was conducted of infants under age 1 year who were admitted with acute hepatitis. The exclusion criteria consisted of: autoimmune, genetic, metabolic, toxic, HAV, HBV, HCV, toxoplasma, rubella, herpes simplex, and Epstein-Barr virus. The 30 patients included were divided into two groups based on markers for CMV (IgM anti-CMV, CMV PCR in urine, CMV culture in urine). Results: The median age of patients (n=15) was 2.8 months. No other organ involvement was detected in any patient. Peak serum total bilirubin levels (n=4) ranged from 2.6 to 6.7 mg/dL. Peak serum ALT levels ranged from 51 to 1,581 IU/L. The duration of ALT elevation ranged from 1.5 weeks to 26 weeks (median 9 weeks). All had recovered in full without ganciclovir; there were no cases of hearing loss. The median age of controls (n=15) was 2.5 months. Peak serum total bilirubin levels (n=4) ranged from 1.6 to 9.1 mg/dL. Peak serum ALT levels ranged from 26 to 1,794 IU/L. No significant differences were observed between both groups regarding the peak serum ALT levels, peak serum total bilirubin levels, duration of hyperbilirubinemia and ALT elevation. Conclusion: Although it was not possible to differentiate congenital infection with perinatal infection in this study, the prognosis of patients with CMV hepatitis without other organ involvement was good without ganciclovir treatment.

  • In clinical chemistry tests, the interfering substances such as hemoglobin, lipid, bilirubin, and drugs, etc. can cause the changes of test results performed by spectrophotometrical methods. We evaluated the effects of interfering substances on the test results by adding interfering substances on the samples in the 19 kinds of clinical chemistry tests such as aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, lactate dehydrogenase, gamma-glutamyltransferase, total protein, albumin, glucose, total cholesterol, total bilirubin, triglyceride, uric acid, calcium, inorganic phosphours, high density lipoprotein cholesterol, low density lipoprotein cholesterol, creatinine, blood urea nitrogen, and C-reactive protein using newly implemented automatic chemical analyzer Toshiba TBA-C8000 under the direction of CLSI EP07-A guideline. Hemolytic samples show increased concentration of total protein, aspartate aminotransferase, alanine aminotransferase, and lactate dehydrogenase and reduced concentration of total bilirubin, alkaline phosphatase by interfering effect. Hyperlipemic samples show increased concentration of total protein and alkaline phosphatase and reduced concentration of low density lipoprotein cholesterol. The samples with conjugated bilirubinemia show increased concentration of inorganic phosphours, otherwise the samples with unconjugated bilirubinemia show no interference or allowable range in the test result.
