  • Purpose: We sought to examine the relationship between the clinical manifestations of nonspecific reactive hepatitis and respiratory virus infection in pediatric patients. Methods: Patients admitted to the pediatric unit of Konyang University Hospital for lower respiratory tract disease between January 1, 2014 and December 31, 2014 and who underwent reverse transcriptase polymerase chain reaction tests were examined. The patients were divided into those with increased levels of alanine aminotransferase (ALT) or aspartate aminotransferase (AST) and those with normal ALT or AST levels. Further, patients with increased ALT and AST levels were individually compared with patients in the normal group, and the blood test results were compared according to the type of respiratory virus. Results: Patients with increased ALT or AST levels had one more day of hospital stay, on average, compared with patients in the normal group ($5.3{\pm}3.1$ days vs. $4.4{\pm}3.0$ days, p=0.019). Patients in the increased ALT level group were younger and had a longer mean hospital stay, compared with patients in the normal group (p=0.022 and 0.003, respectively). The incidences of increased ALT or AST were the highest in adenovirus infections (6/24, 25.0%), followed by enterovirus (2/11, 18.2%) and respiratory syncytial virus A (21/131, 16.0%) infections. Conclusion: Nonspecific reactive hepatitis is more common among patients with adenovirus, enterovirus and respiratory syncytial virus infection, as well as among those infected at a younger age. Compared with AST levels, ALT levels are better indicators of the severity of nonspecific reactive hepatitis.

  • Purpose : The study was performed to assess the distribution of the diseases associated with nonspecific reactive hepatitis (NRH) for the past 10 years and to evaluate the change in the level of AST and ALT, and the difference by several variable factors. Methods : From January 1997 to December 2006, 646 patients had elevated liver enzymes among 22,763 patients admitted to the Holy Family Hospital. We analyzed the difference in the age distribution, the period of elevated levels of AST and ALT, the resolution period, the peak value, the daily resolution value of AST and ALT, the sexual differences and the difference in several disease entities. One hundred and ninety-seven patients not confirmed as NRH or lost during follow-up were excluded. Results : The prevalence rate of NRH was 2.84%. When compared to AST, ALT showed longer period of morbidity and resolution and the peak value was also higher in ALT. The male and female ratio showed significant value of 1.63:1. The morbid and resolution periods of AST and ALT between males and females were longer periods in males. The most prevalent disease entities were respiratory and gastrointestinal infections. Between the respiratory and the gastrointestinal diseases, the highest level of AST and ALT was observed in the respiratory disease. Conclusion : NRH is a common disease that occurs in 2.84% of the admitted pediatric patients. However, the pathogenesis and the progress of the disease have not been well known due to the lack of generalized information. Further research is necessary in the future.

  • Purpose: We compared the therapeutic efficacy of low dose with that of standard dose of interferon (IFN) treatment and also compared the first IFN treatment with retreatment. Methods: We have studied 51 children (age, 2~14) treated for chronic hepatitis B from March 1990 to August 1999. Twenty seven children had been treated with $3\;MU/m^2$ ($2.66{\pm}0.66\;MU/m^2$) of IFN-${\alpha}$ three times a week for 6 months (range, 6~12 months), whereas 24 children with $6\;MU/m^2$ ($4.45{\pm}0.94\;MU/m^2$). There was no significant difference in gender, age, initial ALT and HBV DNA levels between each comparative group. Results: Among the 27 children treated with $3\;MU/m^2$ of IFN, ALT level had normalized in 11 children (41%) and anti-HBe seroconversion occurred in 9 children (33%) one year after the initiation of treatment. In comparison, among the 24 children treated with $6\;MU/m^2$ of IFN, ALT normalized in 12 children (50%) and anti-HBe seroconversion occurred in 7 children (29%). In comparing the first treatment group to retreatment group, ALT level had normalized in 23 children (45%) and anti-HBe seroconversion occurred in 16 children (31%) among the 51 children treated with the first course of IFN treatment. In comparison, ALT normalized and anti-HBe seroconversion occurred in 3 children (25%) among the retreated 12 children. Conclusion: There was no significant difference in the therapeutic efficacies between $3\;MU/m^2$ and $6\;MU/m^2$ dose of IFN treated groups in ALT normalization and anti-HBe seroconversion. The retreatment efficacy of IFN-${\alpha}$ was as effective as the first treatment.

  • The hepatoprotective effects of chalcone derivatives were evaluated in D-galactosamine/lipopolysaccharide (D-GaIN/LPS)-induced fulminant hepatic failure in mouse. Thirteen chalcone derivatives were synthesized for study and their hepatoprotective effects were evaluated by assessing aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels in serum. Chalcone preparations were injected into mice at 12 hand 1 h before intraperitoneal injection of D-GaIN/LPS. After abdominal administration, changes in AST and ALT between the control and treated groups were observed. Ten of the synthesized chalcone derivatives exhibited inhibitory effects on D-GaIN/LPS-induced levels of AST and ALT in mice. Compounds 2, 3, 8, 9, and 12 markedly reduced serum AST and ALT at 8 h, inhibited hepatocyte necrosis and showed significant hepatoprotective activities. The activity of compound 3 was compared with the bifendate (DDB) through oral administration. Compound 3 showed much higher inhibitory effects than bifendate for decreasing AST and ALT activity. The results indicate that compound 3 has strong hepatoprotective activity through suppression of tumor necrosis factor­alpha (TNF-alpha) preduction, reduction of the histological change in the liver, and attenuated of hepatocyte apoptosis confirmed by DNA fragmentation assay.

  • 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.

  • Accelerated life testing (ALT) is a well famous technique in life testing and reliability studies, this is particularly used to induce so high stress leading to failure of the highly reliable units quickly under stipulated duration of time. The step-stress ALT is one of the systematic experimental strategy of ALT applied to fail the units in steps. In this article we focus on two important issues (i) necessity of life tests at higher steps with relevant causes (ii) to develop a new optimum test plan for 3-step SSALT under the modified cumulative exposure model proposed by Khamis and Higgins (1998). It is assumed that the lifetime of test units follows Rayleigh distribution and its scale parameter at constant stress level is assumed to be a log-linear function of the stress. The maximum likelihood estimates of the parameters involved in the step-stress ALT model are obtained. A simulation study is performed for numerical investigation of the proposed new optimum plan 3-step, step-stress ALT. The necessity of the life test units at 3-step step-stress is also numerically examined in comparison to simple step-stress setup.

  • Objectives: The aim of this study was to investigate the safety and the efficacy of Korean herbal, western and combination medicine use in patients with abnormal liver function tests. Methods: We investigated nerve disease patients with abnormal liver function tests who were treated with Korean herbal, western and combination medicine at Dong-Eui University Oriental Hospital from January 2011 to August 2011. We compared aspartic aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and total bilirubin (T-bil) levels before and after taking medicine and excluded patients who had liver-related disease when admitted. Results: AST and ALT were decreased significantly in patients who had taken herbal, western medicine. AST, ALT and ALP were decreased significantly in patients who had taken combination medicine. Compare to herbal medicine, AST, ALT and ALP were decreased significantly in patients who had taken western medicine, and ALT and ALP were decreased significantly in patients who had taken combination medicine. There were no significant differences between western and combination medicine. Conclusions: This study suggests that prescribed Korean herbal medicine, at least, does not injure liver function for patients', moreover, it was shown to be effective in patients with abnormal liver function tests.

  • With the recent development in microsurgery, the use of a perforator flap has been widely implemented. If the length of the ALT flap pedicle is insufficient despite adequate preoperative planning, pedicle length extension is necessary. We planned for a reverse ALT free flap using the distal vessel of the descending branch for pedicle length extension in the case of ALT perforator branch originating from the proximal portion of the descending branch. For the management of venous congestion, the distal venae comitantes were anastomosed to the proximal venous stump in an antegrade manner, successfully resolving the venous congestion. Modified reverse-flow ALT free flap, wherein the venae comitantes are anastomosed to the proximal vein stump, is a good option that allows for relatively simple pedicle extension within the same operative field when securing an adequate pedicle length is difficult because of the origin of the perforator from the proximal descending branch, unlike the initial surgical plan.

  • The antilipidperoxidative and hepatopreventive effects of Aloe water extract (30 mg, 50 mg, 100 mg) were investigated at the levels of liver-total homogenates and the sera of SDrats intoxicated with CCl4 (0.5 cc/100g) and 50% ethanol. We measured MDA (Malondialdehyde) in the liver homogenate, AST (L-Aspartate-2-oxoglutarate aminotransferase) and ALT(L-Alanine-2-oxo-glutraate aminotransferase) in the serum. The analysis of the measurement indicated that Aloe water extract reduced MDA, ALT and AST significantly and their reduction was in relation to dose dependence. In rat liver homogenate intoxicated with ethanol and CCl4, Aloe treatment group markedly inhibited lipidperoxidation by 30%∼70%. In rat serum intoxicated with ethanol and CCl4, Aloe treatment group inhibited AST, ALT by 40%∼90%. In these data Aloe may be used to inhibit or prevent the hapatic toxicity with results from the environmental and alcohlic factors through the further study of its exact antihepatotoxic mechanism.
