This study was conducted to investigate the effect of Hijikia fusiforme extracts on serum lipid and liver antioxidative enzyme activities in triton-induced hyperlipidemic rats. Sprague-Dawley male rats divided into 7 groups : We injected saline to a normal group (N), saline and tween 80 to control groups (CS, CT) and tot extracts to experimental groups (CSA, CTEtOH, CTE, CTH) for 7 days and then injected triton at the last day. Serum and liver free cholesterol contents were significantly lower in hexane-treated group (CTH) than control group (CT) whereas serum HDL-cholesterol content was higher in aqueous extract group (CSA) than control group (CS). Total cholesterol and phospholipid contents in serum and liver were lower in aqueous extract group (CSA) than control group (CS). Serum and liver triglyceride contents were significantly lower in ethanol (CTEtOH) and hexane treated group (CTH) than control group (CT). Thiobarbituric acid reactive substances of liver were lower in tot extract groups (CSA, CTEtOH, CTE, CTH) than control groups (CS, CT). Superoxide dismutase activities in liver were significantly lower in aqueous extracts group (CSA) and hexane treated group (CTH) than control groups (CS, CT). Liver catalase activity was the lowest in ethylacetate extract group. These results showed that some Hijikia fusiforme extracts have reduction effect of lipid and antioxidative effect in triton-induced hyperlipidemic rats.

This study was performed to investigate the effect of dietary $\beta$-carotene supplementation on lipid peroxide levels and antioxidant enzyme activities in alcoholic fatty liver rats. Forty five Sprague-Dawley male rats aging 8 weeks were used as experimental animals, which were divided into the control diet (CD) and the ethanol diet (ED) and the ethanol + $0.02\%$ $\beta$-carotene diet (EPD) groups and fed the experimental diet respectively for 5 weeks. After the feeding, rats were sacrificed to get blood and liver to analyze lipid and lipid peroxide levels and antioxidant enzyme activities. The mean body weight and food intake of the ethanol diet group was significantly lower than that of the control diet. The liver index (LI) of the ethanol diet group was significantly higher than those of the control diet and the $\beta$-carotene supplementation group. Serum levels of total lipid, triglyceride of the ethanol diet group were significantly higher than those of the control diet and the $\beta$-carotene supplementation group. Total cholesterol levels were not significantly different among all groups. HDL-cholesterol of the ethanol diet group was significantly lower than those of the control diet and the $\beta$-carotene supplementation group. Liver TBARS of the ethanol diet group was significantly higher than those of the control diet and the $\beta$-carotene supplementation group. Liver lipofuscin and conjugated diene levels were not significantly different among all groups. The superoxide dismutase activity of the ethanol diet group was significantly lower than those of the control diet and the $\beta$-carotene supplementation group. Catalase and glutathione peroxidase activities were not significantly different among all groups. Because v-carotene supplementation significantly decrease the serum total lipid, triglyceride, liver TBARS revels and increase the superoxide dismutase activity in alcoholic ratty liver rats, $\beta$-carotene supplementation seems to give beneficial effect for the alcoholics.

The purpose of this study was to investigate the improvement effect of mung bean (Phaseolus aureus L.) on the hepatic functional enzyme and catalase activity of streptozotocin (STZ)-induced diabetic rats. Sprague-Dawley (SD) male rats were divided into four groups (n=6), and fed experimental diets containing mung bean meal [basal diet+5% mung bean (BM), basal diet+STZ+5% mung bean (SM)], and control (Basal Diet, BD), BS groups (basal diet+STZ). Serum concentrations of Blood Urea Nitrogen (BUN) and creatinine were significantly decreased (p<0.05) by 5% mung bean supplementation diet. The activities of aspartate transaminase (AST), alanine transaminase (ALT), akaline phosphatase (ALP), lactate dehydrogenase (LDH), amylase and lipase were decreased in the BD, BM and SM group than BS group. The catalase (CAT) activity was significantly increased (p<0.05) in mung bean supplementation diet (BM, SM group) than diabetic group (BS). In vivo experiments with diabetic rats showed that ingestion of mung bean supplementation diet were effective in BUN concentration, and hepatic functional enzyme activities.

Possible mechanism of decreased catechol-O-methyltransferase (COMT) activity in cholestatic rat liver was studied. Hepatic and serum COMT activities were determined from the experimental rats with common bile duct ligation (CBDL). The Michaelis-Menten constants in this hepatic enzyme were also measured. The activities of cytosolic, mitochondrial and mircosomal COMT as well as their Vmax values were found to be decreased significantly in CBDL plus taurocholic acid (TCA) injected group than in the control group, such as CBDL alone groups. However, their Km values in the experimental groups did not vary. Serum COMT activity increased slightly in the CBDL plus TCA injected group than in the control group. The above results suggest that TCA represses biosynthesis of the COMT in the liver. The elevated activity of the serum COMT is believed to be caused by the increment of membrane permeability of hepatocytes upon TCA mediated liver cell necrosis.

The insecticide p-nitropheny diethyl thiophospate is alse known by the symbol E.605 and a legion of trade names including “parathion”. The insecticide is widely used in agriculture, but it is highly toxic and now clear that parathion behaves like a cholinergic drug by inhibiting the enzyme cholinesterase. In order to know acute toxicity and the changes of glucose concentrations and activity according to time lapsed in female mice given orally single with the half dose to $LD_{50}$ of parathion, glucose contents and cholinesterase activities in serum as well as cholinesterase activities in whole brain and spinal cord were investigated, otherwise median lethal dose ($LD_{50}$) of parathion given orally against female mice was determined. The results obtained were summerized as follows ; 1. $LD_{50}$ value of parathion given orally to female mice was 7.1mg/kg(95% confidence limits, 3.8-13.1mg/kg) 2. The inhibition rate of cholinesterase activities in serum of parathion-administrated mice according to time lapsed were peakly decreased to 61% after 30 minutes in comparison to control group, but activities were completely recovered after 48 hours. 3. The inhibition rate of cholinesterase activities in whole brain of parathion-administrated mice according to time lapsed were peakly decreased to 49% after 2 hours in completely recovered after 24 hours. 4. The inhibition rate of cholinesterase activities in spinal cord of parathion-administrated mice according to time lapsed were peakly decreased to 57% after 2 hours in comparison to control group, but activities were completely recovered after 48 hours. 5. The changes of glucose contents in serum of parathion-administrated mice according to time lapsed and in directly after death due to parathion poisoning were no significantly difference.
