The effect of Cimicifuga heracleifolia on CC1$_4$-induced hepatotoxicity was investigated. Cimicifuga heracleifolia has been used to diaphoresis, antipyretics and detoxification in oriental remedy. We examined the effect of Cimicifuga heracleifolia methanol extract by blood chemical analysis and histopathologic examination. ALT and AST were decreased by 38% and 67% in pretreatment group of Cimicifuga heracleifolia compared to CC1$_4$control group respectively. There were significant changes neither in total protein, albumin, triglyceride and cholesterol nor in BUN and creatinine. In histopathologic examination, there were severe necrosis and hemorrhage with infiltration of inflammatory cells around the central vein, zone 3 in the liver of CC1$_4$ treated rat. Ballooning degeneration of hepatocytes were frequently noted in the periphery of the hemorrhagic necrosis. In Cimicifuga heracleifolia pretreatment group, we observed mild degree of ballooning degeneration and inflammatory cell infiltration. No gross necrosis was observed. We measured malondialdehyde (MDA) formation by TBA method. It showed that the formation of MDA in Cimicifuga heracleifolia pretreatment group was decreased compared to the $CCl_4$control group. We got the result of the effect of Cimicifuga heracleifolia on CC1$_4$-induced hepatotoxicity by decreasing serum ALT and AST. It seems that the decrease of lipid peroxidation is related to the recovery effect.

Objectives : This study was undertaken to determine if a combined(SPe) has a protective effect against functional failure induced by $CCl_4$ in rat liver. Methods : Acute liver injury which initiated from free radical induced by $CCl_4$, were applied to rats and data were obtained. Liver injury was estimated by measuring aspartate aminotransferase(AST) and alanine aminotransferase(ALT) activity in serum. Lipid peroxidation was examined by measuring malondialdehyde, a product of lipid peroxidation. GSH activities in liver tissues were also measured. Results : When rats were treated intraperitoneally with $CCl_4$, serum AST and ALT were increased compared with the control, which was significantly inhibited by pretreatment of SPe. SPe also prevented reduction in GSH induced by $CCl_4$. Conclusion : Above results suggest that SPe exerts protective effect against $CCl_4$ by its antioxidant action in liver tissues. Thus, SPe may be used in prevention and treatment of drug-induced liver cell injury. However, the precise mechanisms of SPe protection remain to be determined.

The protective effect of Carthamus tinctorius L. Semen on the carbon tetrachloride induced liver damaged rats were studied. First, methanol extract was prepared and the extract was fractionated with hexane, $CHCl_3$, BuOH and $H_2O$ respectively. Animals were divided into 6 groups and each group was treated with each fraction respectively. To investigate the hepato-protective effect of Carthamus tinctorius L. Semen AST, ALT, albumin, TP, cholesterol, TG, creatinine and total bilirubin values were measured in each treated group and compared with those of control group. GST activity was increased in BuOH group compared with the control group. In malondialdehyde levels, all fractions was decreased compared with the control group. In histopathologic examination, hexane and $H_2O$ fractions of Carthamus tinctorius L. Semen observed mild degree of ballooning degeneration. The results show the protective effect of Hexane,$CHCl_3$, BuOH and $H_2O$ fractions on hepatotoxicity of $CHl_4$ by decreasing ALT, AST, bilirubin, cholesterol, TG and BUN. It seems that the decrease of MDA are related to the recovery effect. The protective effects of Carthamus tinctorius L. Semen fractions in hepatotoxic pathogenesis by $CHl_4$ was suggested in blood chemistry analysis and histopathologic examination.

Carbon tetrachloride (CCI$_4$) induces the hepatotoxicity due to the reactive free radicals generated by cytochrome P-450 (CYP-450) enzyme, which result in destabilization of cellular membrane. Diltiazem, a calcium channel blocking agent, has been known to suppress the CYP-450 enzyme activities. To study the effect of diltiazem in $CCl_4$-treated rats, we measured the activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and glutathione S-transferase (GST), contents of bilirubin, albumin, total protein, cholesterol, triglyceride, blood urea nitrogen, creatinine malondialdehyde and calcium. Also we conducted liver histopathologic examinations. Diltiazem, when administered 1 hour prior to CCI$_4$ treaeent, significantly reduced the activities of ALT and AST, the contents of microsomal malondialdehyde and calcium in liver and microsome as compared with those of $CCl_4$-treated rats. In addition, histopathologic examination showed that diltiazem prevented the development of centrilobular necrosis induced by CCI$_4$ in liver tissue. Our results suggested that diltiazem could inhibit the formation of free radicals and the influx of calcium. Therefore diltiazem may be applied to suppress the liver damage caused by $CCl_4$.

Objectives : Effects of Rhizoma Alismatis extract on lipid composition and TBARS (thiobarbituric acid reactive substances) formation were investigated in rat fed high fat diet. Methods : Seventy male Sprague-Dawley rats were used in these experiments and housed with food and water ad libitum and Twenty rats were selected healthy over 400g body weight and fed high fat diet for 8 weeks. Rhizoma Alismatis extract was administerd at dose 100mg/kg/day, 200mg/kg/day and 300mg/kg/day p.o. for 4 weeks. Then Triglyceride, Total cholesterol, HDL-cholesterol, LDL-cholesterol, TBARS concentration and ALT(Alanine Aminotransferase), AST(aspatate transaminase) activities were determined. Results : Plasma total LDL-cholesterol showed a tendancy to decrease in all treated group(P<0.05), however plasma HDL-cholesterol, total cholesterol, triglyceride showed no significantly different. Rhizoma Alismatis extract feedings resulted in a decrease in plasma TBARS(p<0.05) concentration and AST, ALT activites but contents of TBARS in liver showed no significantly different among all the treatments. Conclusions : Reviewing these experimental results, it appears that Rhizoma Alismatis extract was effective for inhibiting lipid peroxidation and decreasing LDL-cholesterol concentration.

DW2282,(S)-(+)-4-phenyl-1-[1-(4-aminobenzoyl)-indoline-5-sulfonyl]-4,5-dihydro-2-imidazolone hydrochloride, is a new anticancer agent which is thought to exhibit a characteristic mechanism of action in the inhibition of tumor growth. In this study, we estimated the toxicities of DW2282 in mice. When mice were orally dosed for five consecutive days at the dosages of 50, 100 and 150 mg/kg, DW2282 did not induced methemoglobinemia and hypoglycemia at any of these doses. However, increased ALT and AST values were observed in the 150 mg/kg dosing group, and white blood cells (WBC) were significantly decreased at all doses. However, the changes in WBC count, ALT and AST immediately reversed after the cessation of drug administration. In addition, we found that DW2282 did not cause an increase in hemolysis in human blood. Taken together, these data suggested that DW2282 may have a relatively low level of toxicity, and that there may be a quick recovery from any toxicity it dose produce.

The author was performed to investigation of current status of prevalence for anti-hepatitis C virus (HCV) among the health-checkup adults in Jeonbuk province. A toal of 1,553 (male 1,046, female 507) serum samples were diagnosed by 3rd generation enzyme immunoassay (EIA) for anti-HCV. Total prevalence of anti-HCV was 0.9%, and prevalence of male and female were 0.8% and 1.2%, respectively. The prevalence of female was higher than male. According to ages group, prevalence of anti-HCV was highest in 60 age group, but it was not found in 20 age group. 14 samples with anti-HCV positive were diagnosed by EIA for hepatitis B virus surface antigen (HBs Ag), by chemiluminescence immunoassay (CLIA) for serum albumin, alanine transaminase (ALT) and asparagine transaminase (AST). Positive for HBs Ag was not found. The mean of serum albumin levels was 4.5 g/dL, and mean of ALT and AST were 34.3 IU and 31.9 IU, respectively. Through this study, I know that the prevalence of anti-HCV among adults in Jeonbuk, and suggest that the positive of anti-HCV persons who have lower serum albumin, normal to mild elevations in serum enzymes are chronic hepatitis.

The purpose of this study was to probe the influences of krill (Euphausia superba) meal with NaF oral administration on a dose-effect relationship between fluoride levels of krill meal and serum enzyme activity such as alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and lactate dehydrogenase (LDH) in rats fed experimental diets for 5 weeks. There were no significant decreases in the activities of ALP, AST, ALT, and LDH in sera among krill meal diet groups (KF10, KF20, KF30). However, these groups were significantly (p<0.05) lower enzyme activities than normal diet (ND) plus NaF 10 mg group (NF). The fluoride levels of serum and organ tissues (liver, brain, heart, lung, kidney) in NaF 10 mg groups (NF, KF10, KF20, KF30) were significantly increased by adding krill meal in comparison with normal diet group. The results indicate that a difficult to found toxicity to the tissues from krill meal diet groups.
