In this research, as a method for verifying the efficacy of Ssangwhatang and fungus-fermentated Ssangwhatang, a comparative study on the liver protection effect was conducted using animal experiments by inducing the liver toxicity with the $CC_{l4}$ treatment. Inducing the liver damage resulted in the increase in the serum AST and ALP activity, and one day administration of the test material($CCI_4$: 0.5 ml/kg/day) caused 520 IU/L of the ASP activity leading to 29% enhancement in comparison with the normal group and 93% and 81% reductions in the fungus-fermentated Ssangwhatang-administered groups, BFST1 and BFST2, respectively. ALT is 42 IU/L for the normal group and 99 IU/L for the negative control group leading to 135% enhancement. 15 ml/kg/day and 30 ml/kg/day administrations of fungus-fermented Ssangwhatang(BFST) resulted in 51% and 45% decreases in the ALT concentration, respectively. One day administration of 30 ml/kg Ssangwhatang and fungus-fermentated Ssangwhatang caused the LDH in the plasma to tend to decrease. $CCI_4$(1.0 ml/kg/day) administered at the 0th and 4th days led to the observation of the tendency toward the decrease in AST, ALT, and LDH contents. The results indicate that the function of Ssangwhatang is partly reinforced under the fungus-fermentated Ssangwhatang performed in order to verify the efficacy of Ssangwhatang' s effect on the recovery from fatigues.

The variation in the enzyme activities of human liver usually represents the particular physiological conditions of each individuals. Thus, we investigated the variation in the activities of SOD, HR and LPO of (1) non-exposed workers (56 subjects), and (2) exposed workers to DMF (43 subjects) in synthetic leather process. Serum levels of enzyme activities of exposed workers (AST:$30.26{\pm}20.041$U/L, ALT:$32.72{\pm}23.393$U/L, GGT:$28.47{\pm}18.635$ U/L, ALP:$81.77{\pm}34.879$ U/L)were slightly higher than those in nonexposed workers (AST:$24.00{\pm}9.441$ U/L, ALT:$23.89{\pm}18.305$U/L, GGT:$21.95{\pm}17.970$U/L, ALP:$70.84{\pm}24.678$U/L), but only the level of ALT was statistically significant (p< 0.05). Serum levels of LDH, TRF and CHOL in non-exposed workers were slightly higher than those of exposed workers. However, they were not statistically significant (p > 0.05). Serum levels of HR and LPO of the exposed workers appeared to be reduced, but not those of the non-exposed workers. The SOD activities of exposed workers were also slightly higher than those of non-exposed workers, but the results were not statistically significant (p > 0.05). The level of HR was increased with age, but the SOD level was not. These results suggest that the intermittent exposure to DMF at time-weighted average (TWA) level (10 ppm/$m^3$) has affected on the activities of enzymes such as AST, ALT, TRF, but not on the generation of HR, activity of SOD. However, if high dose of DMF was used, there would be severe effects for the generation of HR and LPO.

This study was conducted to investigate the effect of acorn extracts on the antioxidative enzyme system. Male Sprague-Dawley rats(110$\pm$10g) were fed on containing normal and high fat diets. They were orally administrated (0.02g/100g B.W) of acorn ethylacetate-extract and water-extract at the same time once a day, respectively. Net weight gain and feed efficiency ratio were increased in high fat diet groups and decreased by acorn extracts administration. The effect of acorn extracts on hepatic glutathione peroxidase(GSH-Px), glutathione S-transferase(GST) and catalase activities did not show significancy in normal fat diet groups. GST and catalase activities and lipid peroxidation content(LPO) were significantly increased in high fat diet groups and this increment were decreased by acorn extracts administration. However GSH-Px activity and GSH content were decreased in high fat diet groups but increased by acorn extracts administration. The activities of lactate dehydrogenase(LDH), alkaline phosphatase(ALP) and aminotransferase in serum were significantly increased in high fat diet group but these increment reduced in acorn extracts administration groups. These results indicate that acorn extracts could improve the liver function and prevent the metabolic diseases by hyperlipidemia.

To determine the effects of exposure to formalin on the secondary stress indices, changes in haematology and blood chemistry were monitored in healthy crucian carps (Carassius auratus). Fishes were separately exposed in a concentration range of 125 to 500 ppm formalin for 60 min. After exposure, red blood cell (RBC) count and packed cell volume (PCV) were elevated in the 500 ppm formalin exposed group. However, mean corpuscular volume (MCV) and mean corpuscular haemoglobin (MCH) were decreased significantly in the 500 ppm formalin exposed group. Total protein, albumin, aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatinine, total bilirubin, inorganic phosphorus (IP) and magnesium were significantly increased at a concentration of 500 ppm. Alkaline phosphatase (ALP) and glucose were increased at a concentration of 500 ppm, but this was not significant. Lactate dehydrogenase (LDH) and calcium were significantly decreased at concentrations of 250 and 500 ppm. AST, ALT, glucose and magnesium were significantly increased in the 250 ppm formalin exposed group. These results suggests that formalin exposure might cause some damage in the liver and kidney of crucian carp.

The suppressive effects of glutathione-enriched Saccharomyces cerevisiae FF-8 strain (FF-8 GY) on alcoholinduced hepatotoxicity have been studied. FF-8 GY (256 mg/L) from the fermentation at a large scale bioreactor was used. Either of 5% FF-8 GY or 5% commercial glutathione-enriched yeast extract (GYE) with or without 30% alcohol was tested with rats for 4 weeks. FF-8 GY and GYE were found to reduce those alcohol-elevated serum alanine aminotransferase (ALT), alkaline phosphatase (ALP), and lactate dehydrogenase (LDH) activities. Blood alcohol and acetaldehyde were also decreased by FF-8 GY and GYE. Interestingly, FF-8 GY drastically increased both hepatic alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) activities in comparison to GYE group, thus FF-8 GY would be more effective in blood alcohol and acetaldehyde reduction. Attenuated lipid droplet accumulation in hepatocytes was observed in both FF-8 GY and GYE when alcohol stimulated the accumulation. Therefore, FF-8 GY may be useful to protect liver from alcohol-induced hepatotoxicity.

Recently, incidences of pulmonary-related diseases are increasing and natural ecosystem is destroyed year by year owing to air pollutions by industrial noxious gases such as sulfur dioxide and carbon dioxide, etc. Sulfur dioxide produced by oxidation of sulfur compounds is water soluble and causes several kinds of pulmonary diseases, damaging on plants and animals. This study was undertaken to investigate effects of acute exposure of rats to sulfur dioxide using biochemical parameters. The sAST (aspartate transaminase) activity was not significantly affected but sALT (alanine transaminase), sLDH (lactate dehydrogenase) and sALP (alkaline phosphatase) activities were significantly increased by acute sulfur dioxide gas exposure. Also sulfur dioxide gas treatment significantly diminished serum cholinesterase activity. The total lipid, triglyceride, total-, HDL- and LDL-cholesterol contents were significantly increased by sulfur dioxide gas exposures. But the body and liver weight were generally diminished in comparison with control group. Our results' showed increased enzyme activities and lipid contents, but body and liver weight were all diminished by sulfur dioxide gas treatment.

The effects of fruiting body of Cordyceps militaris on the growth, the food intake, the food efficiency ratio, the lipid metabolism, the serum protein level ad enzyme activity in male rats were studied. Sprague-Dawley rats were fed four types of diets for five weeks, respectiely: a control diet, a control diet supplemented with 2%, 3% or 4% fruiting body of Cordyceps militaris(CF) powder. In rats fed 2% or 3% CF diets the body weight gain, the food intake, the concentratons of hepatic triglyceride and serum LDL-cholesterol, the atherogenic index, and the total lipid, total cholesterol, triglyceride and phospholipid in serum were similar to those in rats fed the control diet. Whereas, in 4% CF diet these were significantly decrased. But the all CF diets feeding could not decrease the food efficiency ratio, the weights of liver, pancreas, spleen, kidney and heart, and the concentration of serum HDL-cholesterol. Also, it was shown that the concentrations of glucose, total protein, albumin, urea and creatinine, and the GOT, GPT, LDH, ${\gamma}$-GTP and ALP activities were the same levels in serum of rats of fed all the experimental diets.

The methanol extract of waxy brown rice fermented with Agrocybe cylindracea was prepared. The extract was then freeze dried and fed to rats at the level of 0.5, 1.0, 2.0 g/kg body weight for 14 days, followed by the treatment with carbon tetrachloride for three consecutive days to induce hepatotoxicity. After sacrificing the rats, the enzyme activity of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), and ${\gamma}$-glutamyl transpeptidase (${\gamma}$-GTP) in serum was determined. Biochemical analysis on serum for albumin, total protein, triglyceride, and total as well as HDL-cholesterol were carried out along with a histopathological study of liver tissues. Based on these data, we suggest that the waxy brown rice cultured with A. cylindracea may exert hepatoprotective activity against hepatotoxicity caused by chemicals such as carbon tetrachloride.
