To evaluate the preventive effects of methanolic extract of Angelica koreana(MEAK), this extract was given to rats orally at various doses of 10, 50 and 100 mg/kg before hepatotoxicant, benzo$(\alpha)pyrene$ treatment The increased serum enzyme levels of aspartate aminotransferase (AST), alanine aminotransferase(ALT) and alkaline phosphatase(ALP) by benzo$(\alpha)pyrene$ induction were significantly lowered in a dose dependent manner after pretreatment with MEAK. Furthermore, MEAK also decreased the elevated lipid levels after benzo$(\alpha)pyrene$ administration. These results revealed that MEAK could afford a significant protective action in the alleviation of benzoBenzo$(\alpha)pyrene$ induced hepatocellular injury.

Sachungwhan reduced hepatotoxicity induced by carbon tetrachloride($CCl_4$). Improved liver function was observed by measuring the activities of aspartate aminotransferase(AST), alanine aminotransferase(ALT), alkaline phosphatase(ALP), blood urea nitrogen(BUN), creatinine(CRE), total cholesterol(TCHO), triglyceride(TG), low density lipoprotein cholesterol(LDL-CHO), high density lipoprotein cholesterol(HDL-CHO), total protein(TP), albumin(ALB) and total bilirubin(BIL) in serum. Hepatic parameters monitored were levels of cholesterol(CHO), triglyceride(TG), malondialdehyde(MDA), content of cytochrome P450(CYP), level of glutathione(GSH), and activities of NADPH-CYP reductase, superoxide dismutase(SOD), catalase(CAT), glutathione S-transferase(GST), glutathione reductase(GR), glutathione peroxidase(GPx). The histopathological examination showed that the treatment of Sachungwhan relieved the ballooning degeneration of hepatocytes which had been generated by $CCl_4$. The results suggested that hepatoprotective effects of Sachungwhan possibly are due to their promising antioxidative activity.

An attempt was made to elucidate the stability of serum metabolites and enzyme activities in blood samples taken from rockfish(Sebastes schlegeli), Israeli carp(Cyprinus carpio) and rainbow trout Oncorhynchus mykiss) under different storing conditions. The concentrations of total protein(TP), albumin(ALB), triglyceride(TG), cholesterol(CHOL) glucose(GLC), phosphorus(P) and sodium(Na), and the activities of alanine aminotransferase(ALT) and aspartate aminotransferase(AST) in serum were investigated for 16 days at $15^{\circ}C$(room temp.) and $4^{\circ}C$ (refrigerative) condition, or frozen at $-20^{\circ}C$ for period of 30 days. Though there was a little difference between fish species, the concentrations of TP, ALB, GLC, P, Na in serum were stable at all storing temperatures, while those of TG, CHOL, ALT and AST were not stable, particularly even at the normal temperature. In general, serum components were more stable at refrigerative and frozen conditions than at room temp. storing. However, it was noticeable that the stability of CHOL in rockfish serum was found to be more unstable at $-20^{\circ}C$ than kept at $15^{\circ}C$ or$4^{\circ}C$.

To study the stress response of coho salmon (Oncorhpohus kisutch) during transportation, the stress responses of the fish confined in a container box filled with freshwater or $5{\%{\circ}}$ salt-water were monitored pre and post 10 hours transportation. Changes of cortisol as the first stress indicator, and glucose (GLC), lactate (LAC), triglyceride (TG), cholesterol (CHOL), sodium ($Na^+$), chloride ($Cl^-$), alanine aminotransferase (ALT), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) as the second stress indicators were compared between the fish in two hauling media. Results showed significantly lower levels of cortisol, GLC, LAC, TG, CHOL and AST in salt-water group than freshwater group, It was shown that using salt-water for transportation could lessen the stress level of the coho salmon.

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 hepatoprotective effect of the ethanolic extract of Coccinia indica fruits in rats treated with carbon tetrachloride. In hepatotoxic rats, liver damage was studied by assessing parameters such as aspartate aminotransferase (AST), alanine aminotransferase (AlT), alkaline phosphatase (AIP) and gamma glutamyl transpeptidase (GGT) in serum, and concentrations of total proteins, total lipids, phospholipids, triglycerides and cholesterol in both serum and liver. The effect of co-administration of ethanolic extract on the above parameters was further investigated. Histopathological study of the liver in experimental animals was also undertaken. Hepatic damage as evidenced by a rise in the levels of AST, AIT, AIP and GGT in serum, and also changes observed in other biochemical parameters In serum and liver showed a tendency to attain near normalcy in animals co-administered with the extract. The normal values for AST (IU/L), AIP (IU/I), protein (g/100 ml) and total lipids (mg/100 ml) in serum (i.e.,20.24, 70.04, 5.72 and 135.54 respectively) were found to alter towards values 32.61, 127.11, 3.83 and 265.91 in hepatotoxic rats. These parameters Attained near normal values (I.e.,22.82, 79.30, 5.22 and 151.24 for AST, AIP protein and total lipids respectively) in ethanolic extract co-administered rats. Profound steatosis, ballooning degeneration and nodule formation observed in the hepatic architecture of $CCl_4$ treated rats were found to acquire near-normalcy in drug co-administered rats, thus corroborating the biochemical observations. Thus the study substantiates the hepatoprotective potential of ethanolic extract of Coccinia indica fruits.

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.
