  • In order to investigate radiation effects on the liver, functional changes of liver were analyzed after irradiation. Doses of 10 Gy, 15 Gy and 20 Gy were exposed partially to the liver of male rats(Sprague-Dawley) with X-ray(4MV linear accelerator) at room temperature. On 1, 2, 4 and 8 weeks after irradiation, sera of the animals were compared with those of unirradiated animal by liver function tests. Enzyme activities in sera such as alkaline phosphatase and concentrations of bilirubin in liver function tests. The content of the activities of many enzymes including alkaline phosphatase in sera were increased slightly with increasing exposure dose in all experiments and the activities of these enzymes increased markedly in 20 Gy irradiated groups. The contents of serum bilirubins including direct and indirect bilirubins increased continuously along with the time lapse after irradiation. However, in 20 Gy irradiated group, the content of serum bilirubin decreased slightly during 2 or 4 weeks after irradiation and increased markedly there after. From these above results, functional changes of the liver were induced in all irradiated groups. Damaged liver was recovered along with time collapsed after irradiation to the doses of 10 Gy and 15 Gy while no recovery was deteced within 8 weeks after irradiation to 20 Gy. These results suggest that careful attontion must be paid to liver not to be included in exposure field in radiation therapy.

  • 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.

  • 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.
