  • The purpose of present study was to investigate the protective effect of silkworm excrement powder (SEP) on alcohol-induced hepatotoxicity in rats. Semisynthetic diet supplemented with SEP (3%, w/w) given to alcohol-feeding rats for 30 days, then blood and tissues were collected, processed and used for alcohol concentration mensuration, various biochemical estimations and histopathological examination. Chronic alcohol administration resulted in significantly increase in the activities of the clinically important liver marker enzymes, alanine aminotransferase (ALT), aspartate aminotransferase (AST), $\gamma$-glutamyl transpeptidase ($\gamma$-GTP) and lactate dehydrogenase (LDH). Also, a highly significant increase in the blood alcohol level by alcohol treatment was observed. But alcohol-induced elevation of ALT and LDH levels markedly prevented and the level of blood alcohol decreased in SEP treated rats as compared to alcohol-administered control rats. SEP supplementation showed highly decreased the concentrations of total lipid, triglyceride and cholesterol in serum, as compared with alcohol treated control rats. Alcohol treatment induced the marked accumulation of large lipid droplets, hepatocytes necrosis and inflammation in the liver, but SEP administration attenuated to alcohol-induced accumulation of lipid droplets and hepatocyte necrosis. The results indicated that SEP may exert a protective effect against alcoholic hepatotoxicity through decreasing the activity of hepatic marker enzymes.

  • Objective : In this study, we investigated the effect of SAL5(mixing extracts of Schisandra chinensis Baillon, Artemisia capillaris Thunb., and Aloe vera Linne) on chronic ethanol-induced fatty liver model. Methods : Sprague-Dawley male rats were fed Liber-DeCarli (normal), ethanol liquid diet (control), SAL5 (200 mg/kg). We administrated the SAL5 on chronic ethanol-induced fatty liver model for 5 weeks. We measured alkaline phosphtase (ALP), alanine transminase (ALT), aspartate transminase (AST) and ${\gamma}-glutamyl$ transpeptase (${\gamma}-GTP$) in serum and triglyceride (TG), superoxide dismutase (SOD), catalase, glutathione (GSH) and malondialdehyde (MDA) level in liver. Liver histopathology was examined by Hematoxylin-eosin and Oil red O staining of the fixed liver tissues. Real-time PCR was performed to measure the mRNA expression of inflammatory cytokines and MMP-2, MMP-9. Results : SAL5 administration resulted in significantly decreased liver marker enzymes activities of alanine transminase (ALT), ${\gamma}-glutamyl$ transpeptase (${\gamma}-GTP$) in serum and triglyceride (TG) activities in liver. The control group decreased the activities of superoxide dismutase (SOD), catalase (CAT) with the reduced level of glutathione (GSH) in liver. On the other hand, SAL5 group increased the activities of SOD, CAT and the level of GSH. SAL5 delayed the development of an alcoholic fatty liver by reversing fat accumulation in the liver, as evidenced in histological observations. The gene expression of mRNA were significantly decreased at the $IL-1{\beta}$, $TNF-{\alpha}$, NOS-II and MMP-2 by SAL5. Conclusions : These results indicate that SAL5 might have protective effect chronic ethanol-induced fatty liver models.

  • This study was carried out to evaluate the relations among workers' general characteristics, work-related behaviors and health related behaviors in a steel industry with 1,134 workers in Pohang. The results were as follows; 1. The mean age of workers was 50 years old and working duration was 15 years and over. Most of them were married(94.5%) and had studied beyond high school (53.0%). They performed three shift work and most of them(63.0%) had experienced industial accidents. The frequency of noise and dust exposure was defined by a minimum of 6 hours per day, and workers complained about noise exposure(62.9%) and dust(55.6%). There were current smokers(67.7%), current drinkers(74.3%) and current exercising workers(32.3%) in the industry. The number of cigarette consumption in current drinkers was significantly high $(13.6{\pm}8.4\;pieces/day)$ and the alcohol consumption in current smokers was significantly high$(104.5{\pm}113.5\;g/wk)$. And the number of cigarette consumption of exercisers was significantly low and the alcohol consumption of exercisers was higher than non-exercisers. 3. The ratio of current smokers on frequent noise in exposed workers versus non-exposed workers was not significantly high but the current drinkers in frequent noise and dust exposed workers was significantly higher than non-exposed. 4. The normal levels of SGOT workers in non-smokers were significantly higher than in current smokers, and the normal levels of LFT (SGOT, SGPT, $\gamma-GTP$ workers in nondrinkers were significantly high. The normal levels of SBP and DBP workers in current smokers were not significantly high but were significantly high in non-drinkers. 5. The ratio of current smokers in voters unsatisfied with their job and working condition was higher than non-smokers, but the ratio of current drinkers in workers satisfied with their job and working condition were higher. 6. The significant factors for SGOT and $\gamma-GTP$ were age, the drinking amount and BMI. But the only significant factor for r-GTP was BMI. The significant factors for DBP were age, the alcohol consumption and BMI. And the significant factors for SBP were age, BMI.

  • Relatively little is known about the signaling mechanism of ginseng saponins (ginsenosides), active ingredients of ginseng, in non-neuronal cells. Here, we describe that ginsenosides utilize a common pathway of receptor-mediated signaling pathway in Xenopus oocytes: increase in intracellular $Ca^{2+}$ concentration via phospholipase C (PLC) and $Ca^{2+}$ mobilization. Ginsenosides induced a marked and robust artivation of $Ca^{2+}$-activated Cl- channels in Xenopus oocytes. The effect of ginsenosides was completely reversible, in a dose-dependent manner with EC$_{50}$ of 4.4 $\mu\textrm{g}$/mi, and specifically blocked by niflumic acid, an inhibitor of $Ca^{2+}$-activated Cl- channel. Intracellular injection of BAPIA abolished the effect of ginsenosides. Intracellular injection of GTP${\gamma}$S also abolished the effect of ginsenosides. The effect of gin senosides on $Ca^{2+}$-activated Cl- currents was greatly reduced by the intracellular injection of heparin, an IP$_3$ receptorantagonist or the pretreatment of PLC inhibitor. These results indicate that ginsenosides activate endogenous $Ca^{2+}$-activated Cl- channels via the activation of PLC and the release of $Ca^{2+}$ from the IP$_3$-sensitive intracellular store following the initial interaction with membrane component(s) from extracellular side. This signaling pathway of ginsenosides may be one of the action mechanisms for the pharmacological effects of ginseng.ts of ginseng.

  • Phosphoinositide 3-kinases (PI3Ks) play key roles in synaptic plasticity and cognitive functions in the brain. We recently found that genetic deletion of $PI3K{\gamma}$, the only known member of class IB PI3Ks, results in impaired N-methyl-D-aspartate receptor-dependent long-term depression (NMDAR-LTD) in the hippocampus. The activity of RalA, a small GTP-binding protein, increases following NMDAR-LTD inducing stimuli, and this increase in RalA activity is essential for inducing NMDAR-LTD. We found that RalA activity increased significantly in $PI3K{\gamma}$ knockout mice. Furthermore, NMDAR-LTD-inducing stimuli did not increase RalA activity in $PI3K{\gamma}$ knockout mice. These results suggest that constitutively increased RalA activity occludes further increases in RalA activity during induction of LTD, causing impaired NMDAR-LTD. We propose that $PI3K{\gamma}$ regulates the activity of RalA, which is one of the molecular mechanisms inducing NMDAR-dependent LTD.

  • This study was designed to investigate the differences of physiological variables by age group in alcohol-consuming men. The thirty year old-age group had the lowest waist-hip ratio (WHR), right and left cardio-ankle vascular index (R-CAVI and L-CAVI), right and left ankle-brachial index (R-ABI and L-ABI), amylase, high sensitivity C-reactive protein (hs-CRP), and creatine phosphokinase (CPK) levels, and the highest body weight (BW), interleukin-6 (IL-6), right and left intraocular pressure (R-IP and L-IP), hematocrit (Hct), hemoglobin (Hb), erythrocyte, red blood cells distribution width (RDW), alanine aminotransferase (ALT), total cholesterol (TCH), triglyceride (TG), and ferritin levels. The forty year old-age group was the highest in hs CRp and CPK levels, but the lowest in ferritin level. The fifty year old-age group possessed the highest WHR, diastolic blood pressure (DBP), R- and L-ABI, eosinophil, and amylase levels. The sixty year old-age group had the highest R- and L-CAVI, mean corpuscular volume (MCV), ALP, $\gamma$-glutamyltranspeptidase ($\gamma$-GTP), rheumatoid factor (RF), $\alpha$-fetoprotein (AFP) and prostate specific antigen (PSA) levels and the lowest BW, DBP, R-IP, L-IP, Hct, Hb, leukocyte, platelet, RDW, eosinophil, monocyte, ALT, amylase, TG, and CPK levels. These findings indicate that there may be differences of physiological variables depending on age group in alcohol-consuming men. Further studies should be focused on the physiological differences between alcohol-consuming men and women.

  • High-intensive endurance exercises induce cell changes in body, changes in structures and functions of the heart, the muscles, the cartilages, and the liver, as well as increase of inflammatory cytokine. The purpose of this study was to estimate the biochemical changes in the liver and muscles during ultra-marathon race (100 km) by sections. The blood of the subjects was collected before the marathon as a control in order to analyze serum creatine kinase (CK), lactic dehydrogenase (LDH), asprtate aminotransferase (AST), alanine aminotransferase (ALT), total(T)-bilirubin, direct(D)-bilirubin, total protein, albumin, uric acid, gamma-glutamyltranspeptidase (${\gamma}$-GTP), alkaline phosphatase (ALP), creatinine, blood urea nitrogen (BUN), and high sensitive C-reactive protein (hs-CRP) concentrations. The CK, LDH, D-bilirubin, AST and ALT concentrations at 50 km and 100 km were significantly increased compared to the control (P<0.05). The markers at 100 km were higher than those at 50 km (P<0.05). The T-bilirubin and hs-CRP concentrations showed no difference among the groups, whereas the markers at 100 km were higher than those of the control and at 50 km (P<0.05). In conclusion, this study shows that the ultra-marathon race (100 km) may induce the damage of the skeletal muscle, liver and kidney, intravascular hemolysis and inflammatory responses.

  • The purpose of this study is to inspect trends of the paper of Korean medical treatment on Carbon Tetrachloride-induced Hepatotoxicity and try to establish the future direction for development of Korean herbal medicine. We reviewed 79 papers which had been published from 1981 to 2010 in journals published in Korea. According to these studies, Carbon Tetrachloride-induced hepato-celluar degeneration and necrosis induced to increase in serum aspartate amintransferase (AST), alanine aminotransferase (ALT), Alkaline phosphatase (ALP), ${\gamma}$-Glutamyl transferase (${\gamma}$-GTP), lactate dehydrogenase (LDH), bilirubin, blood urea nitrogen (BUN) and albumin levels. In biochemical analyses, antioxidant enzymes such as superoxide dismutase (SOD), Glutathione S-transferase (GST) and catalase in hepatic tissue were remarkably incresed by Carbon Tetrachloride treatment. We found that some of the herbal extracts have a protective effect against Carbon Tetrachloride-induced Hepatotoxicity. More studies of oriental medicinal herbs are required for developing a treatment of hepatotoxicity.

  • The levels of $\gamma$-aminobutyric acid (GAGA) have been analyzed from pharbitis seeds by an AccQ-Tag amino acid analysis procedure. The GABA level of the pharbitis seeds was 125 nmole per gram fresh weight. To investigate the effects of pharbitis seed diets on serum and hepatic lipid levels, as well as enzyme activities of rats administered with ethanol chronically, Sprague-Dawley male rats were fed with either a AIN-76 diet (control), a control diet plus ethanol, a control plus pharbitis seed diet, or a control plus pharbitis seed diet plus ethanol for 30 days. Pharbitis seed diets decreased the serum total cholesterol, triglyceride, LDL-cholesterol, and $\gamma$-GTP levels that were increased by the chronic ethanol administration. In addition, pharbitis seed diets decreased the liver triglyceride and total lipid levels that were increased by the ethanol administration. However, ethanol metabolism was not retarded by the pharbitis seed supplemented diets. The present Endings, plus previous data showing the differences in the effects of cabbage diets having a high or a low level of GABA on the lipid levels and the enzyme activities of rats (Cha and Oh [2000] J. Korean Soc. Food Sci. Nutr. 29, 500-505), raise the possibility that GABA in plants could have a nutraceutical role in the recovery of chronic alcohol-related diseases.
