To investigate liver toxicity of traditional rice wine, traditional rice wine was prepared by using cooked rice, Rhizopus stolonifier No. 17 nuruk and Saccharomyces cerevisiae. After concentrated the traditional rice wine, it was orally administered into Sprague-Dawley(SD) rats and then changes of its body weight and biochemical parameters of the blood were investigated. All of male and female SD rats did not show any changes in its body weight during two weeks after administering the traditional rice wine concentrates and also biochemical parameters such as aspartate aminotransferase (AST or GOT), alanine aminotransferase (ALT of GOT) and alkaline phosphatase activity were not different compared to control. This results indicated that the traditional rice wine has not any toxicity.

Artemisia princeps PAMPANINI has been used in traditional medicine of the treatment of inflammatory, liver dysfunction and order disorder in the far east countries including Korea. The present study was carried out to investigate the hepatoprotective effects of ethanol extract of Artemisia princeps (AP) and its fermented agents (AP-F) by lactic acid bacteria derived from human intestinal bacteria on liver injured rat induced by $CCl_4$ and d-galactosamine. Hepatoprotective activity was monitored by estimating serum ALT, AST, ALP, LDH, superoxide dismutase (SOD), glutathione redeuctase (GR) and glutathione peroxidase (Gpx) activities in the liver injured by hepatotoxin. Pretreating rats with AP or AP-F at the same dosage regimen significantly suppressed the acute elevation of serum transaminase, ALP, LDH and GR activities, and significantly increased the lowering of blood SOD and GR activites induced by hepatoxin. Based on these findings, it is presumed that AP and APF may have the hepatoprotective effect on $CCl_4$ and d-galactosamine-induced hepatotoxicity rat.

Objectives : This study was undertaken to examine whether Juglandis Semen herbal acupuncture (JGA) exerts protective effect against oxidant-induced cell injury in rabbit liver. Methods : The cell damage was estimated by measuring lactate dehydrogenase (LDH) release, and lipid peroxidation was estimated by measuring malondialdehyde (MDA) in rabbit liver slices. Results : t-Butylhydroperoxide (tBHP) caused an increase in LDH release and lipid peroxidation in a dose-dependent manner over concentrations of 0.5-2 mM, which were prevented by addition of 0.05% JGA. The protective effect of JGA was dose-dependent in concentration range of 0.005 to 0.1%. The concentrations of 0.005 and 0.1% JGA completely prevented the LDH release and lipid peroxidation by 1 mM tBHP. When liver tissues were exposed to 1 mM tBHP, alanine aminotransferase (ALT) activity in the medium was significantly increased, which was prevented by 0.05% JGA. tBHP (2 mM) decreased GSH content and the effect was prevented by 0.05% JGA. Conclusion : These results suggest that JGA exerts protective effect against oxidant-induced cell injury by antioxidant action resulting from enhancement of GSH content in the liver.

This study evaluated the effect of Allium hookeri roots on lipid metabolism of the serum, liver, and adipose tissues induced by a high-fat diet in male Sprague-Dawley rats. The rats were divided into four groups with 8 rats per group for 4 weeks: the normal-diet group (N), the high-fat diet (HFD) group, the HFD containing 3% Allium hookeri (HFD-A3) group, and the HFD containing 5% Allium hookeri (HFD-A5) group. The results showed that the body weight gain and food intake of rats in the HFC-A3 and HFC-A5 groups were significantly decreased compared with those in the HFD group. The epididymal adipose tissue weight in the HFD-A5 group was significantly decreased compared with those in the HFD group, and adipose tissue weights of liver and mesenteric adipose tissues in the HFD-A3 and HFD-A5 groups were significantly decreased compared with those in the HFD group. Serum triglyceride, total cholesterol and LDL cholesterol concentrations, atherogenic index, and cardiac risk factor were significantly lower in the HFD-A3 and HFD-A5 groups than in the HFD group. Serum lipid profiles, as well as ALT and AST activities did not show any difference in all groups. Serum ALP and LDH activities were suppressed in the HFD-A5 group compared with those in the HFD group. The hepatic triglyceride and total cholesterol levels of rats in the HFD-A5 group was significantly lower than those in the HFD group. Moreover, triglyceride and total cholesterol in the epididymal and mesenteric adipose tissues were significantly lower in the HFD-A5 group than in the HFD group. These results demonstrated that the intake of Allium hookeri showed a hypolipidemic effect, changing the lipid metabolsim of a high-fat diet induced rats.

This experiment was conducted to determine the effect of nattokinase (NK) additives on milk production and composition, and blood metabolites in dairy cows. The two kinds of nattokinase with high fibrinolytic activity were produced by two strains of bacteria, Bacillus amyloliquefacines (NK1) and Bacillus subtilis (NK2). Total fifteen Holstein cows (average $1.83{\pm}0.37$ parity; average milk yield $23.2{\pm}3.2$ kg/d) were randomly assigned to three treatments (5 animals per treatment). Cows were fed TMR supplemented with 0g, 100g and 100g for control, NK1 and NK2 treatment, respectively for 4 weeks. Milk yield was significantly higher (p<0.05) for NK1 (22.89 kg/d) than for control (21.07 kg/d) and NK2 (21.36 kg/d). Somatic cell counts in NK treatments were significantly lower than that in control group (58,000 vs. 21,000 and 35,000 cells/ml, control vs. NK1 and NK2). Serum ALT levels in all treatment were similar to the range of 32.00~35.83 IU/L, but AST levels in NK1 (85.67 IU/L) was significantly decreased compared with those in control and NK2 (121.67 and 117.67 IU/L respectively). Serum T-CHO levels in NK1 (145.33 mg/dl) was significantly decreased (p<0.05) compared with that in control (179.00 mg/dl) and NK2 (176.17 mg/dl). This finding showed that NK1 additives could possibly have a positive effect in lactation performance of mid-lactation dairy cows by increasing milk yield, reducing somatic cell count, improving liver function and decreasing cholesterol in blood.

The effects of formalin on mixed function oxygenase (MFO) system and stress-response were investigated in olive flounder (Paralichthys olivaceus). Olive flounder was exposed to formalin at the concentration of 300 ppm for 1, 2, 4 and 16 h. Levels of stress-response enzymes together with total protein, glucose and osmolality were quantitatively determined in blood, and the activities of phase I (cytochrome P450, ethoxyresorufin deethylase) and phase II (glutathione S-transferase) hepatic enzymes were also determined. Since the formalin-exposure for 16 h resulted no significant changes in aspartate aminotransferase and alanine aminotransferase, specific enzymes for liver damage, it was thought that it did not cause hepatic tissue damage at the concentration of 300 ppm. However, hepatic MFO system was induced at 1 to 4 h, and stress response was induced after 16 h of exposure. Moreover, it is considered that the depression of MFO activity after 16 h of exposure may not be adaptation to formalin, but toxic response. These results suggest that low concentration of formalin does not cause hepatic tissue damage of fish, but could induce MFO and stress response.

The aim of the study was to evaluate the effect of sodium nitrate consumption on egg quality and quantity, and some blood parameters of native breeder hens of West Azerbaijan province. One hundred native hens were used from wk 25 to 32 of age. These birds were divided into two groups. One group was fed the control diet (CD) but the other fed the same diet supplemented with 4.2 g/kg sodium nitrate (ND). After 2 wks of adaptation, eggs were collected daily and egg mass and egg production were measured weekly for five weeks. To assess the egg quality parameters, two eggs from each replicate pen were collected for three consecutive days each week. At the end of experimental period (wk 32 of age), blood samples of 5 birds per replicate were collected from the wing vein into anticoagulant tubes. Dietary sodium nitrate didn't affect the egg production, shell stiffness, shell thickness and Haugh unit (p>0.05) but it decreased the both egg production and egg mass during the last three weeks (wks 30, 31 and 32) (p<0.05). Furthermore, a treatment effect was observed for yolk colour (p<0.05). Both the egg production and egg mass were increased over time (p<0.05). No significant treatment${\times}$time interaction was observed for egg weight, egg production and egg mass (p>0.05). No effect of time or treatment${\times}$time were observed for shell stiffness (p>0.05). Over time, shell thickness was decreased while Haugh unit increased (p<0.05). None of the blood TP and TG or the activity of ALT, AST and LDH enzymes were affected by dietary consumption of sodium nitrate at wk 32 of age (p>0.05). Sodium nitrite decreased both the TAC and TC at wk 32 of age (p<0.001). It was concluded that the lower body antioxidant capacity of nitrate fed birds resulted in the lower performance (egg weight, egg production and egg mass).

Chronic alcohol consumption is associated with perturbation of hepatic metabolism of sulphur-containing amino acid. The goal of present study was to evaluate the influence of dietary supplementation of methionine or folate to chronically ethanol-fed mts on the metabolism of sulfur-containing amino acids and one-carbon metabolism. Sprague-Dawley male mts were fed Lieber-Decarli liquid diet with 0% ethanol (control), 36% ethanol (E), 36% ethanol combined with methionine supplement (EM) or folate supplement (EF) for 8 weeks. Hepatic S-adenosylmethionine (SAM) and S-adenosylhomocysteine (SAH), plasma folate and homocysteine (Hcy), urinary excretion of folate and formiminoglutamate were investigated after feeding experimental diets. Growth was retarded by 36% ethanol consupmtion (E, EM and EF) (p<0.01). Liver total fat (p<0.05) and plasma ALT (P<0.01) were increased by methionine supplementation (EM), implicating fatty liver and liver injury. Liver folate was increased slightly by folate supplementation (EF) (p=0.077). Urinary folate loss was increased 2.3 fold by ethanol consumption (E) and 17.2 fold by folate supplementation (EF), while decreased by methionine supplementation (EM) (p<0.000l). Plasma Hcy was increased 1.9 fold by methionine supplementation (EM) in ethanol-fed mts (p<0.05), which was related with decreased methionine synthase activity (p<0.05). Hepatic SAM/SAH ratio was depressed by methionine supplementation in ethanol-fed mts (EM) (p<0.05). Urinary formininoglutamate (Figlu) excretion after histidine loading was increased by ethanol ingestion and reduced by methionine supplementation (p<0.00l). Based on these data, methionine supplementation appears to accelerate histidine oxidation. In conclusion, dietary supplementation of methionine to ethanol-fed mts exacerbates alcoholic liver injury possibly by complicating sulphur-containing amino acid metabolism, as while it may have beneficial effects on folate and histidine metabolism.
