This study was performed to investigate the antioxidative effect of Ligusticum chuanxiong Hort extracts (LCE) against the hyperlipidemia of high-fat diet-fed obese rats. The rats were divided into the three groups (normal group, control group and sample group) to perform the experimental research. 1.5 ml/kg of LCE was intraperitoneally administered into the sample group for 21 days. The equal dose of 0.9% saline was intraperitoneally administered into the normal group and the control group. On day 22, they were anesthetized with ether and dissected. The levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT) were examined in serum of rats. Superoxide dismutase (SOD) was measured in mitochondrial fraction. Malondialdehyde (MDA), catalase (CAT), and glutamate peroxidase (GPx) were determined in liver homogenate. High-fat diet markedly increased the levels of AST, ALT and MDA, significantly decreasing those of SOD, CAT and GPx. But Ligusticum chuanxiong Hort-pretreatment decreased the levels of AST, ALT, and MDA. increasing those of SOD, CAT and GPx. These results demonstrated the antioxidative effects, suggesting that LCE could be the candidate for the functional material.

Objectives : This study was performed to compare the preventive effect of water extracts from Injinho-tang and Haninjinho-tang on hyperlipidemia and liver damage induced by alcohol. Methods : Except for the normal group, we fed rat on 25% alcohol for 55 days. And each extract was administrated for the same period. We measured the serum component in rat's blood, body weight and weight of liver. Results : 1. At first, we observed effects of Injinho-tang and Haninjinho-tang on hyperlipidemia induced by alcohol. Injinho-tang group showed significant decrease of triglyceride, body weight in comparison with those of the control group. Haninjinho-tang group showed significant decrease of total cholesterol, triglyceride in comparison with those of the control group. I 2. At second, we observed effects of Injinho-tang and Haninjinho-tang on liver damage induced by alcohol. lnjinho-tang group showed significant decrease of AST (aspartate aminotransferase), ALT (alanine aminotransferase), ALP (alkaline phosphatase), liver weight in comparison with those of the control group. Haninjinho-tang group showed significant decrease of AST (aspartate aminotransferase), ALT (alanine aminotransferase) in comparison with those of the control group. Conclusion : Reviewing these experimental results, it appears that water extracts from Injinho-tang and Haninjinho-tang have pharmaceutical preventive efficacy on hyperlipidemia and liver damage induced by alcohol. Therefore further additional study should be conducted to elucidate in depth the pharmaceutical efficacy of these.

Objectives : Alcohol-induced oxidative stress has been known to injure various tissues or organs. This stress is related with free radicals which are produced as the result of long-term alcohol consumption. Malonyldialdehyde(MDA) is produced by the interaction of free radicals and cell membrane lipids, and indicates the degree of lipid peroxidation indirectly. The purpose of this study was to investigate the relationship between red blood cell(RBC) membrane lipid peroxidation by free radicals, and associated hepatic injuries and hematologic changes. Methods : Thirty-three subjects diagnosed as alcohol dependence according to DSM-IV diagnostic criteria were evaluated within 72 hours after discontinuing alcohol drinking. Clinical characteristics were evaluated by CAGE questionnaire and Korean Michigan Alcoholism Screening Test(MAST). RBC membrane MDA level was measured as the marker of RBC membrane lipid peroxidation. Aspartate aminotransferase(AST), alanine aminotransferase(ALT) and gamma-glutamyltransferase(GGT) were used as the biochemical markers of liver damage due to alcohol ingestion. The alcohol-induced hematologic change was assessed by mean corpuscular volume(MCV). Results : The results were as follows. Clinical characteristics were not different between two groups having normal and abnormal levels of AST, ALT, GGT or MCV. The levels of MDA were not correlated with the clinical characteristics and serum levels of AST, ALT and GGT. However, there was a significant correlation between the levels of MDA and the value of MCV(p=0.017). Conclusions : These findings suggest that oxidative stress in alcohol dependence may not be reflected in liver enzyme markers such as AST, ALT and GGT, but may be reflected in MCV.

In the 5'-flanking region of the D-AAT, AspAT and AlaDH gene, I found three or two pairs of sequences(designated as Pl, P2, P3) which show significant similarity to the E.coli consensus sequences of -35 and -10 for promoters. The spacing between -35 and -10 is 16 to 18bp in all the three putative promoters Pl, P2 and P3 which is in good agreement with the preferred spacer length in E.coli and in B.subtilis. Therefore, the putative promoters may also function to increase the efficiency of transcriptional initiation. The most stable, double-helical“Shine-Dalgarno”pairing is formed with a free energy change(ΔG) of -13.0 kcal/mol, -9.6 kcal/mol, -15.8 kcal/mol.

Objective: The purpose of this study was to investigate the level of safety on liver functions when Korean herbal medicine was taken internally. Method: 101 inpatients who took Korean herbal medicine were enrolled and liver function test (aspartic aminotransferase, alanine aminotransferase, alkaline phosphatase, total bilirubin, gamma glutamyltranspeptidase, albumin, lactate dehydrogenase) was performed on admission and 1 month later. Results: In 101 patients, alkaline phosphatase and gamma glutamyltranspeptidase decreased significantly compared with the value taken on admission (p<0.05) but aspartic aminotransferase, alanine aminotransferase, total bilirubin, albumin, and lactate dehydrogenase were not significantly changed (p>0.05). In the patients who took Scutellaria baicalensis (n=34), alkaline phosphatase decreased and albumin increased significantly (p<0.05). Among the patients who took Atractylodes macrocephala (n=29), alkaline phosphatase decreased significantly (p<0.05). In the patients who took Glycyrrhiza uralensis or Paeonia lactiflora, liver function parameters were not significantly changed (p>0.05). On admission 11 patients had abnormal liver function and 2 patients had liver injury while 7 patients had abnormal liver function and 2 patients showed liver injury 1 month later. Conclusions: This study suggests that prescribed Korean herbal medicine does not injure liver function.

The hepatoprotective effect of Cordyceps militaris culture broth was determined using HaM/ICR strain mice. Compared to control, the intra-peritoneal injection of benzo($\alpha$)pyrene (B($\alpha$)P) remarkably increased the activities of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in the serum and the level of lipid peroxide (LPO) in liver tissue, which mean the liver was damaged by B($\alpha$)P. However, compared to B($\alpha$)P, oral administration of C. militaris culture broth showed decrement of AST, ALT, and LPO activities and increment GST activity and GSH level in liver tissue. These suggest that C. militaris culture broth recovered hepatic damage induced by B($\alpha$)P.

Olive flounders, Paralichthys olivaceus, were intraperitoneally challenged with Edwardsiella tarda or Streptococcus iniae or both bacteria simultaneously. The pathogenicity was respectively compared with blood chemical using alanine aminotransferase (ALT), aspatate aminotransferase (AST), glucose and total protein, lysozyme activity, bacterial number of kidney and spleen, histopathological change, and cumulative mortality. The tested group of coinfection showed increased cumulative mortality, bacterial number of kidney and spleen, AST and histopathological change, but not in lysozyme activity compared with others. This study provides support for the conclusion that simultaneous infection with Edwardsiella tarda and Streptococcus iniae in a susceptible host results in higher pathogenicity, leading to the increment of bacterial number and the destruction of the internal organs.

The purpose of this study was to evaluate the changes of liver function test before and after treatment in patients admitted to Korean medicine hospital. We checked liver function test level (aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, total bilirubin, direct bilirubin) of 147 patient who admitted in Korean medicine hospital from July 1, 2015 to June 30, 2018. The subjects were selected those who took herbal medicine continuously during the admission period and who performed liver function test on admission and before discharge. And the subjects were excluded those who had a history of liver and biliary disease at the time of admission or who took hepatoprotectants. Aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase significantly decreased compared with the values of admission(p<0.05), but total bilirubin and direct bilirubin were not significantly changed(p>0.05). On admission 31 patients(21.1%) had abnormal liver function and 6 patients(4.1%) had liver injury while 19 patients(12.9%) had abnormal liver function and 6 patients(4.1%) showed liver injury before discharge. This study suggests that herbal medicine may not injure liver function.

Objectives: The objective of this study is to investigate the effects of Silbi-um (SBU) extract on the alcoholic fatty liver induced by EtOH administration for 8 weeks. Methods: Male Sprague Dawley rats were used. All animals were randomly divided into 3 groups; Normal, EtOH and EtOH+SBU. The rats of EtOH group were daily treated with ethanol of 25% (v/v) for 8 weeks (n=10). EtOH+SBU group was orally treated with SBU water extract after ethanol administration (n=10). The rats of Normal group were treated with saline (n=10). After 8 weeks, the mean body weight, liver weight, and liver-body weight ratio were calculated. The serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) of all groups were measured. The morphological alterations were observed using hematoxylin and eosin (H&E) and Oil Red O staining. Moreover, the alteration of tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$) levels were analyzed immunohistochemistrically. Results: The histological data showed that liver sections from EtOH group displayed severe steatosis. SBU extract significantly inhibited the progression of the alcoholic liver injury. The increased serum level of ALT and AST induced by ethanol administration were decreased by SBU extract. Furthermore, SBU extract significantly decreased the liver concentrations of $TNF-{\alpha}$. Conclusions: SBU water extract attenuated the alcohol induced fatty liver by improving hepatic lipid metabolism via suppression of $TNF-{\alpha}$ protein. SBU could be effective in protecting the liver from alcoholic fatty liver.
