  • Icariside II, a flavonol glycoside, was isolated from the aerial part of Epimedium Koreanum Nakai by the anti-hepatotoxic acitivity guided fractionation technique employing $CCl_4-in-toxicated$ primary cultured rat hepatocytes as an assay system. Its anti-hepatotoxic activity was evaluated by measuring activity of glutamic pyruvic transaminase released from the $CCl_4-in-toxicated$ primary cultured rat hapatocytes. Icariside II significantly reduced the activity of glutamic pyruvic transaminase released from the $CCl_4-in-toxicated$ primary cultured rat hepatocytes and resulted in 78% recovery of the toxicity at the concentration of $200{\;}\mu\textrm{m}$. The anti-hepatotoxic activity of icariside II on the $CCl_4-in-toxicated$ primary cultured rat hepatocytes was as potent as that of silybin.

  • The Hexane Extract (HE) and Ethyl Acetate Soluble Fraction of the Methanolic Extract (EASFME) of the fruit pulp of Momordica dioica Roxb. (Cucurbitaceae) was evaluated for its anti-hepatotoxic activity in rats. Acute hepatotoxicity was induced by administering paracetamol (2 g/kg, p.o.) for 3 days. The extracts, at a dose of 400 mg/kg (p.o.) administered for 7 days exhibited a significant therapeutic effect by lowering Serum Glutamate Oxaloacetate Transaminase (SGOT), Serum Glutamate Pyruvate Transaminase (SGPT), Serum Alkaline Phosphatase (ALP) and Serum bilirubin and increasing the serum protein levels. These biochemical observations were supplemented by histopathological examination of the liver sections. The activity of extract was also comparable to the standard drug Silymarin, which is a well-known natural anti-hepatotoxic drug.

  • Cudrania tricuspidata have been used for anti-inflammatory, anti-hepatotoxic, anti-hypertensive and anti-diabetic activities. In this study, in order to investigate the efficacy of antioxidant activity, the bio-activity guided fraction and isolation of physiologically active substance were performed. H$_2$O, 30%, 60%, 100% MeOH and acetone fractions were examined antioxidant activity by DPPH method. It was revealed that 30%, 60%, 100% MeOH frations have significantly antioxidant activity.

  • The purpose of this meta-analysis was to investigate the anti-hepatotoxic effect of ginseng in rats induced with CC14 or TCDD, the toxicities that cause liver damages. Primary studies were collected from the ScienceDirect database, the DBpia, and the KISS. The data on the effect factors in plasma and in enzyme are listed as many as possible: The effect factors were alanine transaminase(ALT), aspartate transaminase(AST), liver aminopyrine N-demethylase(AD), liver aniline hydroxylase(AH), liver 3,4-Methylenedioxyamphetamine(liver MDA), cytochrome P450(P450), serum alkaline phosphatase(ALP), serum lactate dehydrogenase(LDH), cytochrome b5(Cyto b5), glutathione reductase (GR), Liver glutathione S-transferase(GST), liver glutamyltransferase (GT), Liver($\gamma$-GCS), serum liver 3,4-Methylenedioxyamphetamine(serum MDA), serum sorbitol dehydrogenase(SDH), serum total protein(TP), and serum $\gamma$-glutamyltransferase($\gamma$-GT). In order to investigate the effect of ginseng, the standard mean difference(HG) between the group of rats induced with toxicity(RH) and the group of rats induced with ginseng(RHG) were combined, and the significance of HGs were tested. The combined HGs checked the biases caused by heterogeneity among studies and the publication biases. Then they were adjusted by using the random effect model and trim and fill method. Although the publication biases were assumed, among all plasma factors the HGs of ALT, AST, serum MDA, SDH, TP, and $\gamma$-GT were significant, and among all enzyme factors the HGs of liver MDA, Cyto b5, GR, GST, and GT were significant. The treatment with ginseng significantly affected the plasma and enzyme levels in rats induced with toxicity.

  • The aim of this meta-analysis was to systematically investigate the anti-hepatotoxic effect of ginseng in rats induced toxicity which damage to liver. Primary researches were gained on the ScienceDirect database, the DBpia, and the KISS, and the data about the effect factors in plasma and in enzyme were listed as many as possible. The effect factors were alanine transaminase (ALT), aspartate transaminase (AST), liver aminopyrine N-demethylase (AD), liver aniline hydroxylase (AH), liver 3,4-Methylenedioxyamphetamine (liver MDA), cytochrome P450 (P450), serum alkaline phosphatase (ALP), serum lactate dehydrogenase (LDH), cytochrome b5 (Cyto b5), glutathione reductase (GR), Liver glutathione S-transferase (GST), liver glutamyltransferase (GT), Liver (${\gamma}-GCS$), serum liver 3,4-Methylenedioxyamphetamine (serum MDA), serum sorbitol dehydrogenase (SDH), serum total protein (TP), serum ${\gamma}-glutamyltransferase$ (${\gamma}-GT$). To investigate the effect of ginseng, the mean difference (MD) between the group of rats induced by toxicity (RH) and the group of rats induced by toxicity with ginseng (RHG) were combined, and the significance of MDs were tested. The combined MDs were checked the biases caused by heterogeneity among studies and the publication biases, and adjusted by using random effect model and trim and fill method, respectively. The effect about ALT, AST, ALP, LDH, SDH, TP and ${\gamma}-GT$ in plasma factors were significant, and about AD, liver MDA, P450, Cyto b5, GR, GST, GT and ${\gamma}-GCS$ in enzyme factors were significant. The treatment with ginseng supplementation was significantly effected on plasma and enzyme factors of damaged-rats.

  • Standard combination chemotherapy including isoniazid, rifampin, pyrazinamide, and ethambutol is very effective against tuberculosis. But, these medicines can cause hepatotoxicity which is the main reason for treatment interruption or change in drug regimen. In order to identify risk factors associated with hepatotoxcity in Koreans and assess elevated baseline LFTs' contributions to hepatotoxicity, a retrospective case control study was performed. The medical records of 277 patients who diagnosed with tuberculosis at a community hospital from January 1st, 2007 to June 30th, 2010 were reviewed. Patients were categorized into 3 groups (non toxic group, patients without increase in LFT levels; mild to moderate hepatotoxic group and severe hepatotoxic group). And the correlation between risk factors and hepatotoxicity was analyzed by using SPSS program. The overall incidence of hepatotoxicity was 18% and 8.7% of patients developed severe toxicity. Patients in the severe toxic group had the longest treatment period among the three groups. In 75% of severe toxic group, hepatotoxicity occurred within 18.3 days after starting medication. Hypoalbuminemia (serum albumin <3 g/dl) was a significant risk factor for development of severe toxicity. Elevated baseline transaminase (except ALT), total bilirubin, and preexisting hepatitis were also risk factors which were more than twice as likely to increase risk of severe hepatotoxicity (p>0.05). In conclusion, hypoalbuminemia (serum albumin level <3 g/dl) was a significant risk factor for anti-tuberculosis druginduced severe toxicity. Therefore, before starting antituberculosis chemotherapy, serum albumin level should be assessed at baseline. In high-risk patients (hypoalbuminemia, elevated LFTs) for hepatotoxicty, liver function should be closely monitored up to at least 21 days after taking medication.

  • Total methanolic extract of Chrysanthemum coronarium L. var. spatiosum (Compositae) was revealed to have anti-hepatotoxic activity against galactosamine-induced toxicity on primary cultured rat hepatocytes. After successive partitioning with chloroform, n-butanol, and water, the chloroform fraction showed a significant inhibition activity of 51% at 50 ppm, compared with that of silybin, 45.9% at $100\;{\mu}M$. The chloroform fraction was subjected to silica gel column chromatography and yielded active CH-II, CH-V and CH-VI subfractions, and the anti-hepatotoxic activity of these subfractions were 47.6, 56.3, and 23.2%, respectively, at 50 ppm. Total glutathione contents of CH-II, CH-V, and CH-VI increased by 49.8, 43.9, and 47.5% of the control, respectively at 50 ppm, whereas that of silymarin was, 59.7% at $100\;{\mu}M$ after challenged with galactosamine. The ratio of (reduced glutathione) / (total glutathione) in CH-II, CH-V and CH-VI subfraction showed similar values of $0.86{\sim}0.87$ at 50 ppm, whereas that of silymarin was, 0.85 at $100\;{\mu}M$. The incorporation of $[^3H]-uridine$ uptake into RNA was not affected by these active subfractions.
