The findings of serum biochemical tests in the inhabitants residing in some riverside areas of kyongsangnam-do were analized to know the correlation with the Clonorchis sinensis infection. A total of 2,722 fecal samples of inhabitants was examined by Kato's cellophane thick smear and formalin-ether sedimentation methods, and their serums were analized biochemically. Three hundred and thirty-three inhabitants (12.2%) were positive with C. sinensis eggs (egg-positive group), and remaining 2,389 were negative (egg-negative group). In the egg-positive group, the positive .ate of aspartate aminotransferase (AST) was 6.9% (male: 10.3%; female: 3.2%), that of alanine aminotransferase (ALT) was 6.3% (male: 9.1%; female: 3.2%), of $\gamma$-glutamy1 transpeptidase ($\gamma$-GIP) was 9.0% (male: 13.1%; female: 4.4%), and that of $\alpha$-fetoprotein (AEP) was 3.0% (male: 2.9%; female: 3.2%). In the egg-negative group, the positive rate of AST was 5.2% (male: 8.9%; female: 3.2%), that of ALT was 5.1% (male: 8.6%; female: 3.2%), of $\gamma$-GTP was 7.5% (male: 13.0%; female: 4.5%), and that of AFP was 0.3% (male: 0.5%; female: 0.1%). In the egg-positive group, 127 cases (38.1%) were light infection, 108 (32.4%) were moderate infection,64 (19.2%) were heavy infection, and 34 (10.2%) were very heavy infection. The positive rates of all tests were high according to the intensity of infection. From the above results, It was confirmed that prevalence of clonorchiasis is still high in some riverside areas of Kyongsangnam-do, and findings of serum biochemical tests are not different between the egg-positive group and egg-negative group. However, there were some difference in the positive rates of serum AST, ALT, $\gamma$-GTP and AEP by the age, sex and the intensity of infection.

Objectives: Boo-ja and Cheon-o are not commonly prescribed, but are necessary for some clinical conditions, dispite the fact that some negative effects have been known to occur with these medicines. Hence, consequences for aspartate aminotransferase (AST), alanine aminotransferase(ALT) due to herbal medicines, including boo-ja and cheon-o are here reported. Methods: From January 2005 to July 2005, iresults were analyzed for 40 inpatients belonging to the sixth internal medicine department of Dongeui Oriental Medical Hospital who took herbal medicine, including boo-ja and cheon-o, over 20 days. The study is about the comparison and the investigation of LFT, and all results were taken upon their hospitalization and upon their departure. The standard of liver injury was used as a standard for their examinations. Results : 1. No Change in normal limit . 34 of the 40 2. Increased AST. ALT from when they were hospitalized : 2 of 40 Normalized AST, ALT from when they were hospitalized with results higher than normal : 6 of 40 3. These results show no side-effects, therefore suggest that these herbal medicines, including boo-ja and cheon-o. do not cause adverse side-effectsfor patients of this kind if administered as was done in this study.

The aim of this study was to investigate the protective activities of daidzin, daidzein, genistein or puerarin, active isoflavonoids of Puerariae Radix, on the hepatocyte injury induced by carbon tetrachloride (CCl$_4$, 10 mM), tert-butyl hydroperoxide (TBH, 0.5 mM) and D-galactosamine (GalN, 30 mM). Primary cultures of rat hepatocytes (18 hr cultured) were treated with CCl$_4$, TBH or GalN and various concentrations (0.1, 1, 10 and 100 ${\mu}$M) of daidzin, daidzein, genistein or puerarin. CCl$_4$ significantly increased the levels of lactate dehydrogenase (LDH), alanine aminotransferase (ALT) and aspartate aminotransferase (AST). The increase in LDH level was attenuated by daidzein, genistein and puerarin. Puerarin also inhibited the increase in AST level induced by CCl$_4$. The increases in LDH and ALT levels induced by TBH were significantly attenuated by daidzin and genistein treatments. GalN markedly increased the levels of LDH, ALT and AST These increases were significantly attenuated by daidzein. Daidzin also inhibited the increases in LDH and AST levels induced by GalN. The increases in LDH and ALT levels were attenuated by genistein and puerarin, respectively. These results suggest that daidzin and daidzein possess hepatoprotective activities.

The aim of this study was to investigate the protective effects of glycynhizin, active glycosides of Glycyrrhizae Radix, and baicalin, bioactive flavonoid isolated from Scutellariae Radix, on hepatocyte injury induced by carbon tetrachloride(CCl$_4$, 10 mM), tert-butyl hydroperoxide (TBH, 0.5 mM), and D-galactosamine (GaIN, 30 mM). Primary cultures of rat hepatocyte (18 hr cultured) were treated with CCl$_4$, TBH, or GaIN and various concentrations (0.1, 1, 10, and 100 ${\mu}$M) of glycyrrhizin or baicalin. Activity was accessed by determining the release of lactate dehydrogenase (LDH) and aminotransferses. CCl$_4$ significantly increased the levels of LDH, alanine aminotransferase (ALT), and aspartate aminotransferase(AST) and these increases were prevented by baicalin concentrations of 0.1,1, and 100 ${\mu}$M. The increases in ALT and AST levels were reduced by glycyrrhizin concentration of 100 ${\mu}$M. The level of LDH was markedly increased by TBH, and this increase was reduced by both glycyrrhizin and baicalin. ALT and AST levels were increased by TBH, which were prevented by glycynhizin and bacalin, respectively: GaIN markedly increased the levels of LDH, ALT and AST These increases was significantly reduced by both glycyrrhizin and baicalin. These results suggest that glycynhizin and baicalin possess the hepatoprotective activity.

Purpose: Liver metabolism plays a pivotal role in the development of metabolic disorders. We aimed to investigate the clinical and laboratory risk factors associated with alanine aminotransferase (ALT) levels in young adolescents from an urban population in Korea. Methods: A population of 120 apparently healthy adolescents aged 12-13 years was included in the cross-sectional design study; 58 were overweight or obese and 62 were of normal weight. We estimated anthropometric and laboratory measurements, including waist-to-height ratio, blood pressure, insulin sensitivity, aspartate aminotransferases (AST), ALT, and lipid profiles. Results: The mean ages of the overweight or obese and normal weight participants were $12.9{\pm}0.3$ and $13.0{\pm}0.3years$, respectively. Height, weight, body mass index, waist circumference, waist-to-height ratio, systolic and diastolic blood pressure, AST, ALT, total cholesterol, low-density lipoprotein-cholesterol, triglyceride, insulin, and the homeostatic model assessment of insulin resistance (HOMA-IR) score were significantly higher and the high-density lipoprotein-cholesterol and quantitative insulin-sensitivity check index were significantly lower in the overweight/obese participants in comparison to the normal-weight participants (all P<0.05). In multivariate linear regression analysis, waist-to-height ratio, systolic blood pressure, and HOMA-IR score were independently and positively associated with serum ALT levels. Conclusion: Screening for ALT levels in adolescents may help to differentiate those at risk of metabolic abnormalities and thus prevent disease progression at an early age.

The antilipidperoxidative and hepatopreventive effects of Houttuynia cordata extract(HCE) were investigated at the level of liver homogenates and serum of SD rats intoxicated EtOH(3g/kg for 3days). We measured MDA(malondialdehyde) in the live. homogenate, AST(1-aspartate-2-oxoglutarate aminotransferase) and ALT( 1-alanine-2-oxoglutarate aminotransferse) in the serum. The analysis of the measurement indicated that HCE reduced MDA, ALT and AST significantly and their reduction was in relation to dose dependence. In rat liver homogenate intoxicated with EtOH, HCE treatment group inhibited lipidperoxidation by 50-75%. In rat serum intoxicated EtOH, HCE inhibited AST and ALT by 40-70%.

목 적: 최근 10년간 비특이 반응성 간염(NRH)과 자주 동반되는 질환의 분포 그리고, AST와 ALT 수치의 변화 양상과 여러 변수에 의한 차이를 알아보고자 이 연구를 시행했다. 방 법: 1997년 1월부터 2006년 12월까지 성가병원에서 입원치료 했던 22,763명 중에 간 수치가 상승된 환자는 646명 이었다. 이 중에서 NRH의 정의에 부합하지 않거나 추적 관찰되지못한 197명을 제외한 449명을 대상으로 NRH의 나이별 발생 빈도, AST와 ALT 수치의 이환기간, 회복기간, 최고수치, 일당 회복수치 비교, 남녀에 따른 차이 및 질환에 따른 차이를 분석했다. 결 과: NRH의 유병율은 2.84%였다. AST에 비해 ALT의 이환기간과 회복기간이 길고, 최고수치도 높게 나왔다. 남녀 비는1.63 : 1로 유의한 차이를 나타내었다. AST와 ALT 수치 이환기간과 회복기간에서 남자가 여자보다 길게 나타났다. 그리고 호흡기 감염과 위장관염이 가장 많은 빈도를 보였다. 호흡기 감염과 위장관염을 분석했을 때 호흡기 감염이 위장관염보다 AST 와 ALT의 최고수치가 높았다. 결 론: NRH는 소아입원환자의 2.84%에서 나타나는 흔한 질환이다. 그러나 이에 대한 일반적인 인식이 부족한 편이어서 질환의 기전이나 경과가 잘 알려져 있지 않다. 향후 이 질환에 대한 많은 연구가 있어야 하겠다.

The mechanisms by which leptospires caused disease are not well understood. A number of putative virulence factors have been suggested, but with few exceptions their role in pathogenesis remains unclear. In these days, many cases of leptospirosis are diagnosed by serological immunoassay. Leptospirosis is characterized by the histopathology of liver, kidney, heart, and lung, but the electrophoresis fractions of serum protein are not compared. We analyzed total protein, albumin, aspartic aminotranferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), creatinine and urea nitrogen (UN) in sera of patients diagnosed leptospirosis. Total protein and albumin were decreased in 18.5％ and 31.2％ of patients, respectively. AST, ALT, ALP, UN and creatinine were increased in 90.4％, 66.9％, 28.0％, 15.9％ and 10.8％ of patients, respectively. We performed cellulose acetate membrane electrophoresis (EP) on sera of patients increased both of AST and ALT, and of patients increased both of creatinine and UN. In patients increased both of AST and ALT, and in patients increased both of AST and ALT, the relative percentage of albumin to total protein in patient serum was dcreased in 89.1 ％ of patients. α₁-globulin, α₂-globulin, β-globulin and γ-globulin were increased in 85.1 ％, 75.2％, 33.6％ and 98.0％ of patients, respectively. In patients increased both of creatinine and UN, the relative percentage of albumin to total protein in patient serum was dcreased in 93.8％ of patients. α₁-globulin, α₂-globulin, β-globulin and γ-globulin were increased in 87.5％, 100％, 31.2％ and 93.8％ of patients, respectively. These data indicate that infection of Leptospira causes severe liver damage to most of leptospirosis patients, but doesn't cause renal damage to most of them. The relative rate of serum protein electrophoresis fractions to total protein are not identical with them of typical hepatitis patient.
