The rates of deterioration of contractile forces of isolated hearts from ginseng component treated rats were determined. Rat papillary muscles were also used to study the influence of ginseng on the mechanical performance of heart. Rats weighing 200-300g were administered orally with ginseng ethanol extract (100mg/kg/day), ginseng total saponin (50mg/kg/day) and ginsenoside Rbl (5mg/kg/ day) for a week respectively. The isolated hearts from rats were perfused with Krebs-Henseleit solution by Langendorff perfusion apparatus. The force-velocity relation was clearly seen with the load-generator equipped isotonic shortening recording apparatus. The control group was only able to maintain 60% of their initial contractile forces after 120 minutes of perfusion, whereas ginseng ethanol extract treated group was able to sustain nearly their initial strength even after 120 minutes of perfusion. The similar effects were seen in the hearts treated with total ginseng saponin and ginsenoside Rb$_{1}$. Ginseng ethanol extract did alter mechanical performance of rat ventricular myocardium. It increased both maximum velocity(Vmax) of isotonic shortening and isometric force (P$_{0}$) and showed increased velocity of shortening significantly (P<0,05) at any one afterload.d.

Chunggansan was tested for the effects on detoxication mechanism of alcohol. Chunggansan was treated firstly into samples, and then ethanol intoxicated animal models were set with them. The administration of Chunggansan to the rats increased proportionally in alcohol dehydrogenase activities in liver in relation to the level of concentration and days of treatment. Especially, the alcohol dehydrogenase was the most active when the concentration of extract was 200mg/kg and it was 7th day. The enzyme activities of alcohol dehydrogenase and aldehyde dehydrogenase in liver highly increased in Chunggansan pre-medicating group compared to that of ethanol treated group. Also, the blood ethanol concentration in rats was considerably decreased. In conclusion, Chunggansan recovers the damage of liver due to acute alcohol intoxication by the increased enzyme activities of alcohol dehydrogenase and aldehyde dehydrogenase.

The concentration of neurotransmitters in rat brain was determined by HPLC-ECD (electrochemical detection) method and the effects of methanol extracts of some crude drugs, such as Polygala Radix, Myristicae Semen, Zizyphi Semen, Acori graminei Rhizoma, Visci Herba, Liriopsis Tuber, Myrrha on the concentration of neurotransmitters in the ethanol-treated rat brain were investigated. By the administration of ethanol, dopamine (DA), 3, 4-dihydroxyphenyl acetic acid (DOPAC) and serotonin (5-HT) levels in frontal cortex and 5-HT level in hippocampus were significantly increased compared with the neurotransmitter levels in the brain of saline-treated rats. The ${\gamma}$-aminobutyric acid (GABA) level in frontal cortex was decreased by the same treatment. There was a tendency that the DA level in frontal cortex and striatum of ethanol-treated rats were increased by the administration of crude drug extracts. Especially, Myrrha and Visci Herba significantly increased the DA level of frontal cortex in ethanol-treated rats, while they significantly decreased the 5-HT level in the same region of the brain. GABA level in striatum of ethanol-treated rats was significantly decreased by Myristicae Semen, Visci Herba and Myrrha. These results suggest that the tested crude drug extracts have selective interaction with neurotransmitters in specified region of central nervous system.

This study was performed to investigate the effect of normal diet with or without naringin supplement on the lipid and antioxidant metabolism in ethanol-treated rats for a short tenn. Male Sprague-Dawley rats were divided into three groups (n=10), which were assigned to one of three dietary categories : $E_8$ : ethanol diet for 8 wks, $E_4N_4$ : ethanol diet for the first 4 wks and normal diet for the last 4 wks, $E_4Nna_4$ : ethanol diet for the first 4 wks and normal diet with naringin supplement for the last 4 wks. Plasma total cholesterol concentrations were significantly higher in ethanol fed rats for 8 weeks. The HDL-C/total-C ratios of the $E_4N_4$ and the $E_4Nna_4$ groups were significantly higher than that of the $E_8$ group, while the atherogenic index was lower in the $E_4N_4$ and the $E_4Nna_4$ groups than in the $E_8$ group. The $E_4N_4$ and $E_4Nna_4$ diets significantly lowered both the hepatic cholesterol and triglyceride levels compared to the $E_8$ group. Accumulation of hepatic lipid droplets was observed to be the highest in the $E_8$ group. In the current study, the naringin supplement to normal diet significantly lowered both the hepatic HMG-CoA reductase and ACAT activities in ethanol pre-treated rats for 4 weeks. Antioxidant enzyme activities were also upregulated when ethanol feeding was ceased. Naringin supplement given for 4 weeks after ethanol cessation resulted in a significant decrease in the plasma cholesterol and hepatic lipids and plasma TBARS as well as the hepatic HMG-CoA reductase and ACAT activities compared to the rats given ethanol diet for the entire 8 weeks. Replacement of normal diet following a short tenn ethanol feeding was effective for the recovery of ethanol-induced fatty liver and for normalizing plasma and hepatic lipid profiles and antioxidant enzyme activities, regardless of an additional phytochemical supplement, naringin. The effect of naringin could seemingly be more evident if its supplementation period had been extended longer than 4 weeks after ethanol cessation.

This study investigated the effects of an ethanol extract of Allium monanthum MAX. (AME) on ethanol-induced hepatotoxicity in rat liver. Sprague-Dawley rats weighing 100～150 g, were divided into 5 groups; normal group (NOR), AME 200 mg/kg treated group (S1), ethanol (35%, 10 mL/kg) treated group (S2), AME 200 mg/kg and ethanol (35%, 10 mL/kg) treated group (S3) and AME 400 mg/kg and alcohol (35%, 10 mL/kg) treated group (S4). AME was fractionated by the following solvents: n-hexane, chloroform, EtOAC and n-BuOH. Antioxidant index of the n-BuOH fraction was 600 ppm, highest among fractions. The growth rate and feed efficiency ratio were decreased by ethanol, but gradually increased to the corresponding level of the normal group by administering AME. The serum ALT activities that were elevated by ethanol were significantly decreased by AME administration. It was also observed that the hepatic activities of SOD, catalase, xanthine oxidase and GSH-Px that were increased by ethanol were also markedly decreased in the AME treated group with compared to ETB. These results suggest that ethanol extracts of Allium monanthum MAX. may have a protective effect on ethanol-induced hepatotoxicity in rat liver.

Hepatoprotective effects of corn gluten hydrolysates (CGH) were investigated in rats orally treated with ethanol (30%(v/v), 3 g/kg body weight/day) for 4 weeks. Six-week old Sprague-Dawley male rats were divided into four dietary groups: normal diet (N), alcohol diet (E), E+CGH 1% diet (CGH-1%), and E+CGH 3% diet (CGH-3%). Body weights and liver indices were not significantly different among the four groups. However, food intakes were lower in the CGH groups than in the normal group (p<0.05). The administration of CGH significantly reduced serum alkaline phosphatase activity by 30% compared to the alcohol diet group. Among the antioxidative enzymes assessed, catalase activity was significantly decreased by 79% in the CGH diet groups compared to the alcohol diet group. In comparison to the alcohol-treated group, aldehyde dehydrogenase activity was increased by 20%, while microsomal ethanol oxidizing system activity was decreased by 20% in the CGH-treated groups. Furthermore, the area under the curve of the blood acetaldehyde concentration versus time profile after the administration of ethanol was significantly lower for the CGH rats than for the ethanol or asparaginic acid treated groups. Thus, CGH seems to offer beneficial effects by protecting against ethanol-induced hepatotoxicity by improving the acetaldehyde-related metabolizing system.

It has been well known that mushroom polysaccharide extracts have superoxide and hydroxyl radical scavenging activities. So we studied the efficacy and anti-oxidative effect of mushroom(Auricularia auricula U.) in rats treated with water and ethanol extracts of Auricularia auricula U after inducing dryness of skin by the application of detergent. The results of the research for of the efficacy and anti-oxidative effect Auricularia auricula U. are as follows thats. Weight gain and feed intake in animals treated with water extracts and ethanol extracts are significantly higher(p<0.05) than animal treated with detergent. Animals treated with water extracts of Auricularia auricula U. compared to animals treated with ethanol extracts have the higher HDL-cholesterol levels in the blood and the lower LDL-cholesterol levels in the blood. SOD-like activity of the ethanol extracts of Auricularia auricula U. was $27.39{\pm}1.61%$ at 2000ppm.

This study was performed to investigate the antidiabetic study effect in ethanol extract of Ailanthicortex(A.C) radici in Streptozotocin(STZ)-induced diabetic rats. Diabetes was induced by intravenous injection of STZ at a dose of 45mg/kg dissolved in citrate buffer. The ethanol extract of A.C radici was orally administrated once a day for 7 days at a dose of 500mg/kg. The content of serum glucose, triglyceride(T.G), total cholesterol were significantly decreased in treated group compared to the those of STZ-control group. The content of hepatic glycogen and activity of glucokinase(GK) were significantly increased in treated group compared to the those of STZ-control group. but activity of glucose-6-phosphate dehydrogenase(G-6-PDH) was significantly increased. These results indicated that ethanol extract of A.C would have antidiabetic effect in STZ-induced diabetic rats.

Chronic or acute alcohol abuse often leads to liver injury associated with alcoholic hepatitis, liver fibrosis, cirrhosis, and liver cancer. In addition to the liver, alcohol abuse also induces a variety of other tissue injuries including pancreatitis, cardiomyopathy, neurotoxicity and muscle loss. Chronic skeletal muscle myopathy, independent of peripheral neuropathy, is well recognised in alcoholic patients. Several mechanisms may be involved in the pathogenesis of alcoholic myopathy. Ethanol is a potent inhibitor of muscle protein synthesis. Gastrocnemius and plantaris muscles are Type II fiber-predominant and usually considered representative of the musculature as a whole. Whereas, soleus muscle is Type I fiber predominant. Shihosogan-san is a traditional Korean medicine that is widely employed to treat indigestion and liver diseases. Muscle diseases are often related to liver diseases and conditions. We therefore tested the hypothesis that treatment with Shihosogan-san could ameliorate the ethanol-induced changes in muscle protein synthesis. Young male Sprague-Dawley rats were orally given 25% ethanol (5ml/kg, body weight) daily with Ethanol for 28 days. Normal group was similarly administrated with saline. In Shihosogan-san treated group, rats were orally administrated Shihosogan-san extract, and rats of EtOH group were given with the vehicle only. After 4 week, the morphology of gastrocnemius and plantaris muscles were assessed by hematoxylin and eosin staining. For comparative purposes, liver function was also investigated. The muscles from rats of EtOH group displayed a significant reduction in average cross section area compared to Normal group. Shihosogan-san treated group had increased fiber compared to the EtOH group. Moreover, Shihosogan-san treated group compared with EtOH group showed significantly decreased pro-apoptotic BAX expression and increased anti-apoptotic Bcl-2 expression. In conclusion, Shihosogan-san extract showed ameliorating effects on chronic alcohol toxicity in skeletal muscle.

This study was conducted to investigate the effect of Cassia tora ethanol extracts on carbon tetrachloride($CCl_4$)-induced hepatotoxicity in rats. Male Sprague-Dawley rats were divided into the following 4 groups: normal group, $CCl_4$, treated group, $CCl_4-0.25%$ Cassia tora ethanol extracts group and $CCl_4-0.5%$ Cassia tora ethanol extracts group. Rats were fed with each experimental diet and water for 5 weeks. Liver weights of rats treated only with $CCl_4$, were significantly increased compared to normal group, but not in rats fed diet containing Cassia tora ethanol extracts. Cholesterol and triglyceride contents in serum and liver were also not influenced by either $CCl_4$, treatment or the supplementation of Cassia tora ethanol extracts. $CCl_4$, treatment significantly increased ALP activities, however the supplementation of Cassia tora ethanol extracts significantly decreased the activities of serum ALT, AST, ${\gamma}-GTP$ in dose-dependent manner. Cassia tora ethanol extracts significantly reduced $CCl_4-induced$ elevation of liver TBARS contents. Activities of superoxide dismutase and catalase were decreased by $CCl_4$, treatment, however by the supplement of Cassia tora ethanol extracts slightly increased activities of SOD and catalase. The activity of glutathione peroxidase in groups fed diets containing Cassia tora ethanol extracts was significantly decreased compared to that of the control group. These results suggest that Cassia tora ethanol extracts may exert protective effect against $CCl_4-induced$ liver injury through the prevention of lipid peroxidation.
