This study was done to investigate the protective effects of Iljungbogan-Tang on acute hepatotoxicity of rats induced by $CCL_4$ and acetaminophen. The subject animals were divided into 3 groups : control group(administrated 0.5% carboxymethyl cellulose), sample group(30, 100, 300, 600mg/kg administrated), positive control group (administrated silymarine), Acute hepatotoxicity of rats were induced by $CCL_4$ and acetaminophen, and the serum transaminase(AST, ALT) were measured for enzyme activities. The inhibitory effects on the serum AST activities were noted in sample group(100, 300, 600mg/kg administrated) on hepatotoxicity of rats induced by $CCL_4$. The inhibitory effects on the serum AST, ALT activities were noted in sample group(30mg/kg administrated) on hepatotoxicity of rats induced by acetaminophen. The inhibitory effects on the serum AST activities were noted in sample group(600mg/kg single dose administrated) on hepatotoxicity of rats induced by acetaminophen. It is considered that Iljungbogan-Tang has protective effects against hepatotoxicity in rats induced by $CCL_4$ and acetaminophen. So it is required to study about the actions of mutual relation of medicines and patho-mechanism through experiment.

The objective of this study was to evaluate the effect of diets containing different amounts of wheat, as a partial or whole substitute for corn, on digestibility, digestive enzyme activities, serum metabolite contents and ruminal fermentation in beef cattle. Four Limousin${\times}$LuXi crossbred cattle with a body weight ($400{\pm}10kg$), fitted with permanent ruminal, proximal duodenal and terminal ileal cannulas, were used in a $4{\times}4$ Latin square design with four treatments: Control (100% corn), 33% wheat (33% substitution for corn), 67% wheat (67% substitution for corn), and 100% wheat (100% substitution for corn) on a dry matter basis. The results showed that replacing corn with increasing amounts of wheat increased the apparent digestibility values of dry matter, organic matter, and crude protein (p<0.05). While the apparent digestibility of acid detergent fiber and neutral detergent fiber were lower with increasing amounts of wheat. Digestive enzyme activities of lipase, protease and amylase in the duodenum were higher with increasing wheat amounts (p<0.05), and showed similar results to those for the enzymes in the ileum except for amylase. Increased substitution of wheat for corn increased the serum alanine aminotransferase concentration (p<0.05). Ruminal pH was not different between those given only corn and those given 33% wheat. Increasing the substitution of wheat for corn increased the molar proportion of acetate and tended to increase the acetate-to-propionate ratio. Cattle fed 100% wheat tended to have the lowest ruminal $NH_3-N$ concentration compared with control (p<0.05), whereas no differences were observed among the cattle fed 33% and 67% wheat. These findings indicate that wheat can be effectively used to replace corn in moderate amounts to meet the energy and fiber requirements of beef cattle.

The present study has been undertaken to investigate the effect of plantaginis semen extract on lipid composition and activities of several enzymes in lard administrated rats. Forth male rats of Sprague-Dawley strain with average weight of 130$\pm$10g were divided into four groups[basal diet(BD)], basal＋plantaginis semen(BP), basal＋lard(BL) and basal＋plantaginis semen＋lard(BLP). Lard administrated groups showed increase in weight gain and that of BLP group significantly increased. Feed intake showed no significant differences with lard administration. The weights of liver, kidney and heart of the rat were not affected by plantagins semen and lard administration. Serum and liver triglyceride and cholesterol contents significantly increased compared to BD group but significantly decreased by the addition of plantaginis semen extract(BLP group). Serum and liver phsophlipids decreased in lard administrated group but effectively restored by administration of plantaginis semen extract. HDL-cholesterol content significantly decreased in lard-fed group and somewhat increased in plantaginis semen extract group. Serum aminotransferase, lactate dehydrogenase activities significantly increased in lard fed group but addition of plntginis semen extract significantly decreased the enzyme activities compared with that of lard administrated group.

Male rats of Albino strain were divided into four groups, control group, X-irradiated group, WR-2721 treatment group and X-irradiated group treated with WR-2721. The radioprotective effect of treatment with S-2 (3-aminopropylamino)ethylphosphorothioic acid (WR-2721) in the dose of 200mg/kg by intraperitonial injection on rats 20min prior to wholebody X-irradiation (8Gy) was studied. Each group determined serum alkaline phosphatase (ALP), aspartate aminotransferase (ASI), alanine aminotransferase (ALT), lactate dehydrogenase (LDH) activities and contents of serum glucose after 1, 3, 7 and 10 days. The ALP and AST activities of X-irradiated group were significantly decreased (p<0.05) compared with that of control group, but X-irradiated group treated with WR-2721 less decreased those enzyme activities compared with the X-irradiated group. X-irradiated group was significantly increased (p＜0.05) ALT and LDH activities compared with that of control group, but X-irradiated group treated with WR-2721 less increased those enzyme activities compared with the X-irradiated group. The concentration of serum glucose of X-irradiated group was significantly increased (p<0.05) compared with that of control group, but X-irradiated group treated with WR-2721 less increased compared with that of X-irradiated group. It may be considered that WR-2721 provided radioprotective effect of organs of body from X-irradiation.

This study aimed to find out the effect of freeze-drying leek against cadmium poisoning on the cholesterol and enzyme activities in serum and superoxide radical, SOD and catalase in liver and kidney of the male rats during the administrered period. In this experiment, male rats of Sprague-Dawley strain were used. The rats were divided into 3 groups which were fed differently either for 5 weeks or for 10 weeks:basal diet, basal diet and cadmium in water and 3 % leek added diet and cadmium in water. Cadmium was administered ad libiturn 100 ppm CdCl$_{2}$ in water. The followings are the results of this experiment. 1. Leek reduced the cholesterol and the activities of GPT increase resulted from cadmium treatment. 2. Leek reduced the rate of cadmium in liver and kidney. 3. Leek reduced the activities of SOR and catalase in liver and kidney, while it enhanced the activities of SOD. 4. Leek reduced the necrosis and swelling in liver and kidney casused by cadmium treatment. This experiment showed that leek-addition group had protective effect against cadmium poisoning and increased ALPase activities in serum. Leek alleviated GPT activities in serum and cadmium concentration, necrosis, and swelling in liver and kidney. Therefore, this experiment concluded that leek has defensive power against cadmium poisoning.

Effects of ginseng on in vivo antioxidant capacities with age were studied in rats. All rats were reared in the conventional system. Ginseng-treated rats were supplied with ginseng water extracts (25 mg/kg/day) continuously from 6 weeks of age to spontaneous death. None of the rats showed any discernible adverse effects of treatment with ginseng-containing water. There was no significant difference in body weight (BW) gains with age between treated and control groups. However, ginseng extracts did cause a decrease in the level of serum low density lipoprotein (LDL)-cholesterol, glucose, and thiobarbituric acid reactive substances (TBARS) in the treated rats. The activities of superoxide dismutase (SOD), catalase, and glutathione peroxidase in liver cytosol decreased with age in the control group. However, these enzyme activities were well maintained in the ginseng-treated rats and, especially, catalase and glutathione peroxidase activities were consistently higher than in control rats. The levels of total sulfhydryl group (T-SH) and glutathione reductase (GR) were unchanged, and glutathione-s-transferase (GST) activity gradually decreased with age in both groups. There were no differences in T-SH, GR, or GST between the control and treatment groups. These results indicate that long-term administration of ginseng retards age-related deterioration in some biochemical parameters such as cholesterol, glucose, and lactate dehydrogenase in serum and it has an enhancing effect on antioxidant capacity in the liver.

Persimmon is well-known as a Korean traditional medicine for alleviating coughs and enhancing blood circulation; it is also used for treatment of hypertension, cancer, diabetes and atherosclerosis. To evaluate the protective properties of persimmon leaf methanol extract (PLME) and persimmon fruit methanol extract (PFME) administration on acute ethanol-induced hepatotoxicity, C57BL/6 male mice were gavaged with or without persimmon extracts for 1 week. Hepatotoxicity was then induced by gavage of 5 g/kg BW ethanol. After 12 hr of ethanol administration, blood and liver were collected and analyzed for biochemical markers of hepatotoxicity. The results showed PLME and PFME treatments decreased the activities of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) compared with ethanol control. Both PLME and PFME reduced serum lactate dehydrogenase (LDH) activity, but elevated alcohol dehydrogenase (ADH) activity. Serum triglyceride (TG) and hepatic cholesterol levels were significantly decreased when treated with PLME and PFME. Liver malondialdehyde (MDA) levels were significantly decreased in PLME and PFME groups compared with ethanol control. Furthermore, the administration of PLME and PFME significantly increased the activities of catalase, glutathione peroxidase (GSH-Px) and glutathione reductase (GSH-red). In summary, PLME and PFME appeared to prevent hepatic injury by accelerating alcohol metabolism by increasing alcohol-metabolizing enzyme activities, by activating the antioxidative enzyme system against oxidative stress, and by decreasing fat accumulation, which is evidenced by decreased hepatotoxic indices in serum.

This study was performed to investigate the effects of the chitosan oligosaccharide administration on the improvement of the lipid compositions, blood glucose and enzyme activities in the serum of hypercholesterolemic rats fed the experimental diets for 5 weeks. Concentrations of total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free cholesterol, cholesteryl ester ratio, triglyceride (TG), phospholipid (PL) and blood glucose in serum were higher in the hypercholesterolemic group (group CW) and cholesterol+chitosan oligosaccharide administration group (group CCW) than those in the control group (group BW, basal diet+water). But the concentrations of total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free cholesterol, cholesteryl ester ratio, TG, PL and blood glucose in serum were lower in the group CCW than those in the CW, whereas the ratio of HDL-cholesterol concentration to total cholesterol and HDL-cholesterol concentration in the group CCW were higher than in the group CW. The activities of alkaline phosphatase (ALP) and aminotransferase (AST, ALT) in serum were lower in the group CCW than in the hypercholesterolemic group CW. From the above results, it was suggested that chitosan oligosaccharide administration was effective in the prevention and improvement of the lipid level, blood glucose and enzyme activities in serum of hypercholesterolemic rats.
