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.

Objective : This study was undertaken to determine if Pyunggangaeuljihyul-tang (Pinggankaiyuzhixue-tang, PG) has a protective effect against cell injury induced by various toxic agents in rabbit liver, Methods : Cell injury in vitro was estimated by measuring lactate dehydrogenase (LDH), and that in vivo was estimated by measuring alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activity in serum. Lipid peroxidation was examined by measuring malondialdehyde, a product of lipid per oxidation. Results : PG prevented the LDH release by $CCl_4$, mercury, menadione, and tert-butyl hydroperoxide treatment in vitro in liver slices. The extent of protection by 2% PG was similar to that of $10{\mu\textrm{M}}$ N,N'-diphenyl-p-phenylenedianline, a potent antioxidant, in tert-butyl hydroperoxide-induced LDH release. PG also prevented lipid peroxidation and depletion of cellular ATP induced by Hg. Hg causes motphological changes including cell necrosis and its effect was significantly prevented by PG. When rats were treated intraperitoneatly with 0.5 ml/kg of $CCl_4$, serum alanine aminotransferase and aspartate aminotransferase activities were increased compared with the control, which was significantly inhibited by pretreatment of PG. PG also prevented reduction in GSH and lipid peroxidation induced by $CCl_4$ Conclusion : These results suggest that PG exerts aprotective effect against various toxic agents by its antioxidant action in liver tissues. Thus, PG may be used in prevention and treatment of drug-induced liver cell injury. However, the precise mechanisms of PG protection remain to be determined.

비파 식초가 사염화탄소에 의한 간독성에 대한 보호효과를 흰 쥐를 이용하여 확인하고자 연구하였다. 4주간 SD rat 암컷을 정상군, 음성대조군, 양성대조군, 비파 식초군으로 나누어 샘플을 처리하였고, 29일째 되는 날 사염화탄소를 처리하였다. 혈청 AST 및 ALT 효소 활성 수치 변화에서 비파 식초가 사염화탄소를 단독으로 투여한 군보다 유의한 수치로 각각 49.77%, 75.88%로 감소하였다(p < 0.001). 간 조직에서는 CAT 및 SOD 효소 활성은 비파 식초군이 사염화탄소를 단독으로 투여한 음성대조군보다 유의한 차이로 높은 활성 수치를 보였다. 조직학적 관찰에서는 비파식초군이 사염화탄소를 단독으로 투여한 음성대조군에 비해 지방변성이 적게 분포하고, 조직의 섬유화가 진행되지 않았으며, 정상군과 비슷한 간세포의 구조가 관찰 되었다. 이와 같은 결과를 보아 비파 식초는 항산화 효소의 증가로 활성산소를 제거하여 간 손상을 억제할 뿐아니라 혈청의 AST 및 ALT 효소 활성을 감소시켜 간 보호 효과가 있는 것으로 건강기능식품으로써 긍정적인 가능성이 있다고 사료된다.

In this study, we investigated the correlation between the administration of various antiviral agents and the alternation of specific biomarkers induced by the hepatitis B virus (HBV). Eligible subjects diagnosed with chronic hepatitis B were prescribed with antiviral drugs at the Gastroenterology Internal Medicine Department of E University Hospital in Daejeon between May 2004 and September 2009. Lamivudine was prescribed to 66 out of 100 patients. Of the 12 patients, 6 (50.0%) showed a change from being HBe-antigen-positive to being HBe-antigen-negative. Of the 39 patients, 23 (59.0%) showed higher than 40 IU/L alanine aminotransferase (ALT). Of the 65 patients, 41 (63.1%) showed HBV DNA decrease of 1 log, and were prescribed with Lamivudine. Adefovir was prescribed to 3 out of 100 patients. Of the 12 patients, 1 (8.3%) showed a change from being HBe-antigen-positive to being HBe-antigen-negative, and was prescribed with Adefovir. Entecavir was prescribed to 19 (19.0%) out of 100 patients. Of the 12 patients, 3 (25.0%) showed a change from being HBe-antigen-positive to being HBe-antigen-negative. Of the 12 patients, 3 (125.8%) showed higher than 40 IU/L ALT. Of the 65 patients, 14 (21.5%) showed HBV DNA decrease of 1 log, and were prescribed with Entecavir. Clavudine was prescribed to 7 out of 100 patients. Of the 12 patients, 1 (8.3%) showed a change from positive HBe antigen to negative HBe antigen. Of the 39 patients, 5 (12.8%) showed higher than 40 IU/L ALT. Of the 65 patients, 6 (9.2%) showed HBV decrease of 1 log, and were prescribed with Clavudine. These results do not show a statistically significant correlation between drugs and biomarkers. Data on combination therapy using Lamivudine and Adefovir show no statistically significant difference between drugs and biomarkers. Medications for periodic inspection was not correlated to HBe-antigen-negative conversion, ALT, and HBV DNA. HBV DNA was significantly reduced in patients with high levels of AST(aspartic acid aminotransferase) and ALT before treatment. In addition, the decrease of HBV DNA after 12 months of treatment was less frequently observed in patients treated with Lamivudine compared with other drugs. This result is associated with Lamivudine resistance. Although the association of drugs with diagnostic markers and the correct choice of treatment is difficult to determine, these results may be useful for further research on diagnosis and treatment of the hepatitis B virus.
