The purpose of this study was to probe the influences of NaF oral administration on a dose-effect relationship between fluoride levels of 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. All groups increased the activity of serum ALP, AST, ALT, and LDH levels with increasing NaF. In addition the fluoride levels of serum and organ tissues (liver, brain, heart, lung, kidney) in oral NaF groups (NF3~NF50) were significantly increased by adding sodium fluoride in comparison with normal diet group (ND) (p<0.05). These results, a high concentration of sodium fluoride was determined that the toxicity to various organ tissues.

Biochemical tests such as aspartate aminotransferase (AST) and alanine aminotransferase (ALT) are useful for diagnosing patients with liver disease. In this study, we tested the association between copy number variation and the hepatic biomarkers AST and ALT based on 8,842 samples from population-based cohorts in Korea. We used Affymetrix Genome-Wide Human 5.0 arrays and identified 10,534 CNVs using HelixTree software. Of the CNVs tested using univariate linear regression, 100 CNVs were significant for AST and 16 were significant for ALT (P < 0.05). We identified 39 genes located within the CNV regions. DKK1 and HS3ST3B1 were shown to play roles in heparan sulfate biosynthesis and the Wnt signaling pathway, respectively. NAF1 and NPY1R were associated with glycoprotein processes and neuropeptide Y receptor activity based on GO categories. PTER, SOX14 and TM7SF4 were expressed in liver. DPYS and CTSC were found to be associated with dihydropyrimidinuria and Papillon-Lefevre syndrome phenotypes using OMIM. NPY5R was found to be associated with dyslipidemia using the Genetic Association Database.

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, results were analyzed for 36 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 were as follows : No Change in normal limit : 28 of the 36 Increased AST. ALT from when they were hospitalized : 2 of 36 Normalized AST. ALT from when they were hospitalized with results higher than normal : 6 of 36 These results show no side-effects, therefore suggest that these herbal medicines, including boo-ja and cheon-o, do not cause adverse side-effects for patients of this kind if administered as was done in this study.

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 : 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.

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.

Hepatoprotective activity of methanol extract of Angelica tenuissima Nakai on the $CCl_4$-induced hepatotoxicity was investigated. To elucidate the hepatoprotective activity and free radical scavenging effect, we examined alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin, total protein, cholesterol, malondialdehyde (MDA) levels in serum and activities of superoxide dismutase (SOD), catalase (CAT) in hepatic tissue as compared with those of carbon tetrachloride-induced rats. The action mechanism also has been estimated by quantative analysis of cytochrome P450 (CYP), NADPH-CYP reductase for phase I metabolism and glutathion (GSH), glutathion S-transferase (GST) level for phase II metabolsim. Treatment of Angelica tenuissima methanol extract significantly lowered the levels of alanine aminotransferase and aspartate aminotransferase. In addition, the levels of cholesterol, triglyceride, MDA, CAT were decreased, and SOD was activated. This result indicates that the hepatoprotective effect of Angelica tenuissima methanol extract on the CCl4-induced hepatotoxicity would be originated from reduction of the NADPH-CYP reductase, GSH and the enhancement of the activities of GST, CYP.

Serum alanine aminotransferase(ALT), aspartate aminotransferase (AST), hepatic glutathione, glutathione S-transferase(GST), cytochrome P450 and cytochrome P450 reductase activity were measured to investigate the effects of hepatic detoxication system and metabolic activities of carbendazim in Sprague Dawley(S.D.) male rat at dose levels of 375, 750 or 1,500 mg/kg body weight. Serum alanine aminotransferase(ALT) and aspartate aminotransferase(AST) activities were slightly increased in all test groups after 120 minutes of administration. Glutathione was increased about 20% at high and medium dose level within 120 minutes after administration, while activity of glutathione S-transferase was decreased $36{\sim}50%$. However, the enzyme activity was recovered from all test groups after 240 minutes of administration. Cytochrome P450 and activity of cytochrome P450 reductase were decreased $25{\sim}50%$ until 120 minutes after administration, but recovered after 240 minutes.

The antilipidperoxidative and hepatopreventive effects of Aloe water extract (30 mg, 50 mg, 100 mg) were investigated at the levels of liver-total homogenates and the sera of SDrats intoxicated with CCl4 (0.5 cc/100g) and 50% ethanol. We measured MDA (Malondialdehyde) in the liver homogenate, AST (L-Aspartate-2-oxoglutarate aminotransferase) and ALT(L-Alanine-2-oxo-glutraate aminotransferase) in the serum. The analysis of the measurement indicated that Aloe water extract reduced MDA, ALT and AST significantly and their reduction was in relation to dose dependence. In rat liver homogenate intoxicated with ethanol and CCl4, Aloe treatment group markedly inhibited lipidperoxidation by 30%∼70%. In rat serum intoxicated with ethanol and CCl4, Aloe treatment group inhibited AST, ALT by 40%∼90%. In these data Aloe may be used to inhibit or prevent the hapatic toxicity with results from the environmental and alcohlic factors through the further study of its exact antihepatotoxic mechanism.
