Objective: The aim of the study was to evaluate the hepatoprotective activity of the bark extract (Ethanol: Water) in the ratio of (3:1) of Rhizophora mucronata (BERM) by intoxicating the $HepG_2$ cell lines with different toxicants viz, $CCL_4$, Ethanol and Paracetamol with different concentrations of the extract were used. The $HepG_2$ cell lines were subjected to MTT Assay for studying the cytotoxicity. Methods: $HepG_2$ cells were plated using 96 well plate in 10% bovine serum, exposed to different toxicants viz, 2% $CCl_4$, 60% Ethanol and 14 mM Paracetamol respectively. The various test concentrations (18.85, 37.5, 75, 150 and $300{\mu}g/ml$) of bark extract of Rhizophora mucronata was added and incubated for 24 hours. Medium was removed after incubation period and 0.5 mg/ml MTT(3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) was added and again incubated for 4 hours at 37oC. Then MTT was removed the crystals was dissolved in DMSO and absorbance was measured at 570 nm. Results: The result showed that dose dependent increase in percentage of viability at the doses of 18.85, 37.5, 75, 150, $300{\mu}g/ml$. Te results for the $CCl_4$ intoxicated, at $300{\mu}g/ml$ of the concentration of the extract, the % of viable cells was found out to be 99.6%, for Ethanol intoxicated, 97.67%, and Paracetamol induced, 75.37%, IC50 was $21.53{\mu}g/ml$, $12.61{\mu}g/ml$ and $21.42{\mu}g/ml$ respectively. Conclusion: Thus, we conclude that, the extract possesses defensive effect against different toxicants and can be used as an alternate drug for hepatotoxicity.

In this study, the effect of Epimedii Herba (EH) on the antioxidative enzymatic activity was investigated. EH (100mg/kg) was intraperitoneally administered into rats for 2 weeks. On the last day, carbon tetrachloride $(50\%\;CCl_4,\;3.3ml/kg,\;i.p.)$ dissolved in olive oil was injected before 12 hours. EH-pread-ministered and $CCl_4-treated$ (EC) group showed higher inhibitory effect in aminotransferase (AST, ALT) activity compared to $CCl_4-treated (CT)$ group. Superoxide dismutase (SOD) and Catalase in EC group were increased compared to those of CT group. The activity of glutathione peroxidase (GPx) was significantly higher than those of CT group compared to EC group. These results suggest that EH has a hepatoprotective effect through scavenging the free radicals induced by $CCl_4$.

Scoparia dulcis L. is widely used in the traditional system of medicine for treating liver ailments. In the present study the terpenoids and terpenoid fractions isolated from 1:1:1 petroleum ether, diethyl ether and methanol (PDM) extract of Scoparia dulcis L. were tested for their in vitro 1, 1-Diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity. Selected samples from the assay were further tested for their in vitro hepatoprotective activity against $CCl_4$ induced hepatotoxicity in freshly isolated rat hepatocytes. In the in vitro antioxidant study, fractions 7, 11, 13, 14, and 15 and PDM extract show the DPPH radical scavenging activity. The phytochemical screening of all these fractions show the presence of terpenoids. In the in vitro hepatoprotective study all these fractions and the PDM extract significantly prevent the $CCl_4$ induced changes in the aspartate aspartate amino transferase, alanine amino transferase and alkaline phosphatase levels (p < 0.05). The above results are comparable with the standard, silymarin. The results of the study indicate that, the PDM extract of Scoparia dulcis L. possesses potential hepatoprotective activity and this may be attributed to its free radical scavenging potential, which in turn may be attributed to the presence of terpenoids.

This study was conducted to investigate the effect of Makgeolli and Makgeolli precipitate on hepatotoxity and the serum lipid content in rats. First, we investigated the effect of Makgeolli and ethanol on the progress of alcoholic fatty liver. The effect of Makgeolli precipitate on carbon tetrachloride ($CCl_4$)-induced hepatotoxicity in the rats was then studied. Indicators of the health status of the experimental period, the body weight gain in ethanol-treated group tended to be lower than those in the control and the Makgeolli-treated groups. The weight of the liver tissue decreased significantly following the administration of ethanol. However, this was not seen following the administration of Makgeolli. The activities of serum aspartate transaminase (AST) and alanine transaminase (ALT) were decreased in the Makgeolli group compared to the ethanol group. Serum cholesterol concentrations increased in the ethanol group, but decreased in the Makgeolli-treated group to an equal volume of the ethanol-treated group. The serum HDL-cholesterol content was significantly higher in the Makgeolli group than in the ethanol group. Analysis of the impact of the Makgeolli precipitate on toxicity induced by $CCl_4$ in the liver showed that the $CCl_4$ treatment significantly increased the activities of serum ALT and AST. However, the levels of cholesterol and triglyceride in serum were decreased. The $CCl_4$ treatment increased the activities of AST and ALT. However, the raw Makgeolli precipitate decreased their activities. Moreover, raw Makgeolli precipitate significantly reduced the $CCl_4$-induced elevation of serum lipids more than heated Makgeolli precipitate. These results suggest that raw Makgeolli precipitate may exert a protective effect against $CCl_4$-induced liver injury by preventing lipid peroxidation.

Saengshik which is food not to apply heat is expected to have good effect on the body because metabolic enzymes are preserved in it. In fact, despite of enlargement of saengshik market, the researches on the effect of saengshik are insufficient. So, the aim of this study was to investigate the protective effect of saengshik against $CCl_4-inducing$ hepatotoxicity in ICR mice. As the result of serum biochemical parameters, AST (SGOT) and ALT (SGPT) were significantly decreased at the experimental group treated with saengshik and $CCl_4$ as compared with experimental group 1 treated with $CCl_4$ only (p<0.01). ALP was significantly higher at experimental group 2 compared with control and experimental group 1 (p<0.01). In histological study, experimental group 1 treated with $CCl_4$ only showed severe necrosis all over the liver at the gross observation, and showed severe perivenular necrosis and individual hepatocytic degeneration. However experimental group 2 was not nearly different from control group in appearance and showed mild perivenular necrosis and dominant sever neutrophil infiltration surrounding central veins. The result of this study showed the protective effect against $CCl_4-inducing$ hepatotoxicity and suggest the possibility of the functional health food. However, further studies about the effect of saengshik may be needed.

The effects of Curcuma extract Solomon's seal (Polygonatum odoratum var. pluriflorum), and maltodextrose on acute hepatotoxicity in Sprague-Dawley (SD) rats were investigated. Acute hepatotoxicity was induced by 0.5 mL of carbon tetrachloride ($CCl_4$) per kg of SD rats, which was injected to them before administration of Curcuma extract or both Solomon's seal (Polygonatum odoratum var. pluriflorum) and maltodextrose mixtures. SD rats dose with Curcuma extract of 4 mg or 40 mg per kg per day significantly (p<0.05) reduced the levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALKP) after 7 days compared to the controls dose with water. Treatments of Curcuma extract with 4 mg per kg per day in SD rats significantly (p<0.05) reduced aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALKP) to 78.0%, 82.6%, and 76.3% after 7 days compared to the controls, respectively. The levels of AST and ALT in SD rats dose with both Solomon's seal (Polygonatum odoratum var. pluriflorum) and maltodextrose mixtures or either alone had no significantly different (p>0.05) compared to the controls. Treatments of Curcuma extract combined with Solomon's seal (Polygonatum odoratum var. pluriflorum) and maltodextrose mixtures was 'liked more' to the sensory scores for odor and flayer compared to the controls. It was considered that Curcuma extract combined with both Solomon's seal (Polygonatum odoratum var. pluriflorum) and maltodextrose mixtures could be used to functional food for enhancement of health and consumer acceptance.

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.

This study was carried out to investigate antioxidative, antimicrobial activity and the effect on hepatotoxicity in various extracts of Artemisia iwayomogi. The herb has been used widely for jaundice, hepatitis and liver cirrhosis in chinese medicine. Solid yield by various extraction solvents, 18.1%, was the highest in water extract. To find antioxidative activity in Artemisia iwayomogi was estimated radical scavenging effect by DPPH method in various extracts and change of the POV(peroxide value) of various extracts added in soybean oil during 20 days at $60^{\circ}C$. Radical scavenging effect by DPPH method was the most effective in methanol extract. Added 1,000ppm water extract and methanol extract in soybean oil, the POV of them, 46.8(meq/kg) and 50.8(meq/kg) were lower than that of control, 79.1(meq/kg), during 20 days storage. After antimicrobial activity of various extracts of Artemisia iwayomogi on bacteria was carried out by paper disc method, it found that the ethanol extract was the strongest activity on Vibrio parahaemolyticus. In vivo experiment was to investigate the effect of Artemisia iwayomogi water extract(AIWE) on hepatotoxicity by carbon tetrachloride$(CCl_4)$ in rats. The experiment groups were divided into five groups for recovery(for 3 days) and three groups for protection(for 10 days) in rat liver. The weights and morphological changes of liver and the body weight were examined in each groups. Compared with $CCl_4$ treatment groups$(CCl_4\;only)$, liver and liver/body(%) weights of AIWE pretreatment groups for 3 days and AIWE posttreatment groups for 10 days were declined. In macrography, fibrious exudates and swelling of liver were decreased in AIWE treatment groups. Accumulation of lipid droplets and necrosis of hepatocytes were also decreased in AIWE treatment groups in microscopically. In these results, AIWE seems to enhance hepato-protective and recoverable effect on $CCl_4$ induced hepatotoxicity in rats.

The aim of this study was to evaluate the effects of Welsh onion administration on $CCl_4$-induced hepatic injury in rats. The increasing rate of the body and organ weight was not significantly different by the ad-ministration of the Welsh onion. Welsh onion (2, 4, $10\%$ w/w) was given for 4 weeks with the injections of $CCl_4$. Total serum lipid was significantly decreased in all treatment groups compared to $CCl_4$ only treatment group (p<0.05). The Welsh onion from winter season was more protective effect by lowering the serum levels of transminase (SGOT and SGPT) compared with others, the levels of transminase - phosphatase (ALP) in serum. The Welsh onion from winter at a dose of $4\%,\;10\%$ (w/w) showed significantly hepatoprotective activity which was comparable to that $CCl_4$-induced hepatic damage. Histological evaluation showed that Welsh onion partially prevented $CCl_4$-induced inflammation, necrosis and vacuolation. Pretreatment of Welsh onion reduced extent of the necrosis found 24 hr after the intraperitoneal administration of $CCl_4$. The present study shows the liver protective action of the Welsh onion against experimentally induced liver damage in rats. This suggests that the Welsh onion may be used as an effective hepatoprotective agent.

This study was designed to evaluate the single dose toxicity and the protective effect of water extract of Cordyceps militaris grown upon Protaetia dreujtarsis (CMPD extract) on liver damage on carbon tetrachloride ($CCl_4$)- induced acute hepatotoxicity in Sprague-Dawley (SD) rats. The CMPD extract was once administered orally to both sexes of rats at dose of 2,000, 1,000 and 500 mg/kg body weight, the recommended maximum limit dose for acute toxicity. Neither significant toxic signs nor death was observed during the observation period. These results indicate that $LD_{50}$(lethal dose of 50%) of CMPD extract is greater than 2,000 mg/kg body weight in SD rats. To investigate also the effect of hepatoprotection of CMPD extract, SD rats were orally treated with CMPD extract (50, 25 and 12.5 mg/kg body weight) or silymarin (25 mg/kg body weight) before and after administration of $CCl_4$ (2 mL/kg body weight, 20% $CCl_4$ in olive oil). Treatment with CMPD extract or silymarin could decrease the GPT (glutamic-pyruvic transaminase) and GOT (glutamic-oxaloacetic transaminase) levels in serum when compared with $CCl_4$-treated group. Therefore, the results of this study show that CMPD extract can be proposed to protect the liver against $CCl_4$-induced hepatic damage in rats.
