In order to elucidate the correlation between the lipid peroxidation and hepatotoxicity, the formation of malondialdehyde (MDA) in liver homogenate and serum, and the transaminase activities were determined in intoxicated by ascorbic acid-Fe$\^$2+/-ADP in rat. In a model of ascorbic acid-Fe$\^$2+/-ADP hepatotoxicity, G009, which was obtained from Ganoderma lucidum IY009, exhibited anti-lipid peroxidative effect in rat liver homogenate, and that MDA values of the liver homogenate decreased from 48.1% to 74.8% in comparision to controls (p<0.01) Also, the MDA formation in serum inhibited 66.5% at 100 mg/kg of G009. Serum levels of glutamic oxaloacetic transaminase(GOT) and glutamic pyruvic transaminase(GPT) in peroxidizer-induced rats treated with G009 was decreased compared with control. Especially, The formation of lipid peroxides in serum was related to GPT levels. These results that G009 has a protective effect on ascorbic acid-Fe$\^$2+/-ADP-induced hepatic injury through an inhibition of lipid peroxidation in liver.

The blood components of not-young (young antler) were examined in the Red Deer. Blood samples were collected from the antler and jugular veins respectively. The hematological and serum chemical values were as follows; 1. RBC count of not-hyul (young antler blood) was significantly higher than that of jugular vein blood (p<0.05). However, fibrinogen concentration of rook hyul was significantly lower than that of jugular vein blood (p<0.01). WBC counts packed cell volume (PCV) and total protein fro) were not significant between nolo-hyul and jugular vein blood. 2. The concentration of phosphorous and magnesium of not-hyul were significantly higher than those of jugular vein blood (p<0.05). Albumin and glutamic oxaloacetic transaminase (GOT) of nolo-hyul were higher than those of jugular vein blood. But globulin and calcium concentration of not-hyul were lower than those of jugular vein blood. Blood urea nitrogen BUN) of rook-hyul was not significant when compared with that of jugular vein blood.

This study was conducted to determine the stress response [ethological (operculum movement number (OMN)), hematological (hematocrit and hemoglobin), biochemical (glucose, cortisol and glutamic oxaloacetic transaminase (GOT))] in red spotted grouper, Epinephelus akaara during exposure of different water temperature in winter season. This species (Total length, $18.56{\pm}0.34cm$) previously maintained in water temperature of $15^{\circ}C$ were transferred to 15, 20 and $25^{\circ}C$. During experimental period (7 days), OMN, hematocrit (Ht), glucose and GOT values were significantly high in $15^{\circ}C$ when compared to 20 and $25^{\circ}C$. Hemoglobin value was also increased at $15^{\circ}C$, but no significant differences. There was no differences in cortisol levels among the temperature groups. No fish mortality was observed during the experimental period. From these results, $15^{\circ}C$ is likely more stressful to red spotted grouper than $20^{\circ}C$ and $25^{\circ}C$. These observations confirm that red spotted grouper adapts better to temperatures between 20 and $25^{\circ}C$ during the winter season.

Genome-wide association studies (GWAS) have identified a number of common variants associated with serum liver enzyme homeostasis in population. In the previous study, single nucleotide polymorphisms (SNPs) in several genes have been reported to be associated with serum liver enzyme levels in European population. We aimed to confirm whether the genetic variation of SMAD2 (SMAD family member 2) gene influence the serum liver enzyme levels in Korean population. We genotyped variants in or near SMAD2 in a population-based sample including 994 unrelated Korean adult. Here, we performed association analysis to elucidate the possible relations of genetic polymorphisms in SMAD2 gene with serum liver enzyme levels. By examining genotype data of a total of 944 subjects in 5 hospital health promotion center, we discovered the SMAD2 gene polymorphisms are associated with serum liver enzyme levels. The common and highest significant polymorphism was rs17736760 (${\beta}$=3.51, P=5.31E-07) with glutamic oxaloacetic transferase (GOT), rs17736760 (${\beta}$=5.99, P=1.25E-05) with glutamic pyruvate transaminase (GPT), and rs17736760 (${\beta}$=15.68, P=9.93E-07) with gamma glutamyl transferase (GGT) in all group. Furthermore, the SNP rs17736760 was consistently associated with GOT (${\beta}$=5.25, P=1.72E-06), GPT (${\beta}$=9.97, P=1.16E-05), GGT (${\beta}$=26.13, P=3.43E-06) in men group. Consequently, we found statistically significant SNP in SMAD2 gene that are associated with serum levels of GOT, GPT, and GGT. In addition, these results suggest that the individuals with the minor alleles of the SNP in the SMAD2 gene may be more elevated serum liver enzyme levels in the Korean population.

Serum liver enzyme levels are widely used in the clinical diagnosis of liver diseases and the assessment of liver status. They also have epidemiological significance to be prospective risk factors for type 2 diabetes, cardiovascular disease. In the previous study, single nucleotide polymorphisms (SNPs) in several genes have been reported to be associated with serum liver enzyme levels in American population. We aimed to confirm whether the genetic variation of C16orf47 (chromosome 16 open reading frame 47) gene also influence the serum liver enzyme levels in Korean population. We genotyped variants in or near C16orf47 in a population-based sample including 994 unrelated Korean adult. Here, we performed association analysis to elucidate the possible relations of genetic polymorphisms in C16orf47 gene with serum liver enzyme levels. By examining genotype data of a total of 944 subjects in 5 hospital health promotion center, we discovered the C16orf47 gene polymorphisms are associated with serum liver enzyme levels. The common and highest significant polymorphism was rs7203412 (${\beta}$=3.68, P=3.66E-06) with glutamic oxaloacetic transferase (GOT) and rs7203412 (${\beta}$=6.2, P=7.06E-05) with glutamic pyruvate transaminase (GPT) in all group. Furthermore, the SNP rs7203412 was consistently associated with GOT (${\beta}$=6.41, P=6.78E-08) and GPT (${\beta}$=11.53, P=2.81E-06) in men group. Consequently, we found statistically significant SNP in C16orf47 gene that are associated with serum levels of GOT and GPT. In addition, these results suggest that the individuals with the minor alleles of the SNP in the C16orf47 gene may be more elevated serum liver enzyme levels in the Korean population.

This study was designed to investigate the effect of early protein undernutrition of rats on later susceptibility to lead poisoning. Weanling rats, weighing about 55 grams, were malnourished by feeding low protein diets ( 12% and 5% casein diet ) during the four weeks of protein deprivation period. For the following 5 weeks, the malnourished rats were fed with 25% casein diet as rehabilitation diet. After the rehabilitation period, all rats were fed with 25% casein diet and the drinking water containing 2000ppm-Pb during the four weeks. The results obtained were as follows ; 1 ) Feed intake, body weight gain and food efficiency ratio were reduced in all rats exposed to lead, especially in rats fed with 5% casein diet during the four weeks of weanling period. 2 ) Enlargement of kidney and spleen were observed in all rats exposed to lead and were more remarkable in rats fed with 5% casein diet. 3 ) In rats exposed to lead, activity of serum glutamic oxaloacetic transaminase ( S- GOT ) was significantly increased by increasing the degree of early protein deprivation, whereas hematocrit value was significantly decreased. Activity of serum glutamic pyruvic transaminase ( S- GPT ) was shown a tendency to increase by increasing the degree of early protein deprivation, but the difference was not significant. 4) In rats exposed to lead, the amount of lead accumulation in kidney was increased by increasing the degree of early protein deprivation. The significant increase was shown in rats fed with 5% casein diet during the four weeks of weanling period. The results of the experiment suggest that early protein undernutrition, even after some period of rehabilitation, may enhance the later susceptibility to lead poisoning.

This experiment was conducted to study the effects of medicinal plant extract on performance in broiler chickens. A total of eight hundred forty, 1-d-old broiler chicks(Ross) were randomly allocated to 7 treatments with 4 replicates of 30 birds per replicate. The treatments were negative control (NC, diets without antibiotics), positive control (PC, diets with-containing antibiotics), Schisandrae fructus (T1), Scutellariae radix (T2), Camellia sinensis (T3), Artemisia capillaris (T4) and mixed medicinal plants (T5) extracts added to drinking water. The final body weight, body weight gain and feed conversion rate were significantly improved in all treatments compared to NC (P<0.05). No significant differences were observed in the relative weights of liver, spleen, pancreas, bursa of Fabricius and intestinal tract among the groups. The relative lengths of duodenum, jejunum and ileum were significantly decreased in PC compared with other groups (P<0.05). No significant differences were observed in the cecal microflora. The contents of triacylglycerol (TG), blood urea nitrogen (BUN), glutamic-oxaloacetic transaminase (GOT) and glutamic-pyruvic transaminase (GPT) in blood serum were not significantly influenced. The concentration of cholesterol in blood serum was significantly decreased in all treated groups as compared to those of the control (P<0.05). There was no difference in the components of leukocytes and erythrocytes among the groups.

Objective: The purpose of this study was to determine serum antioxidant nutrients and the relationship between serum antioxidants and risks of chronic diseases in obese Korean children Methods: Normal weight Korean school children (0=170), mean age of 11.5$\pm$1.5, and obese (body fat mass > $28\%$) children (0=176), mean age of 11.0$\pm$1.8, were recruited Fat mass ($\%$) was determnined by Bioelectrical Impedance (BEI), and body mass index (BMI) was calculated Fasting blood was collected to measure serum antioxidant nutrients, vitamin A, vitamin E and zinc. Serum lipid profiles including total cholesterol (TC), high density cholesterol (HDL) and triglyceride (TG), and blood glucose, glutamic oxaloacetic transaminase (GOT), and glutamic pyruvic transaminase (GPI) were also determined. Differences in serum blood measurements between obese and normal children were assessed by independent t test. Pearson's correlation analysis was used to determine the relationship between variables. Results: Blood glucose, GPT, total cholesterol, and triglycerides concentrations were significantly higher among obese boys, compared to normal boys (p<005). Significantly lower concentrations of serum vitamin E, after adjustment for TG and TC, was shown in obese boys (0.26 mg/mg) and obese girls (0.31 mg/mg), compared to normal boys (0.36 mg/mg) and girls (0.38 mg/mg) (p<0.05). Fat mass ($\%$) was negatively con-elated with serum vitamin A and vitamin E. Conclusion: Obese Korean children showed insufficient serum vitamin E concentration and increased risk for diabetes, atherosclerosis, and liver disease. Since lower vitamin E concentration was negatively con-elated with atherogenic index, improved vitamin E status in children may decrease the risk of atherosclerosis later in life.

Betaine is one of the major water-soluble components in Lycii Fructus. In the present study the effect of repeated betaine treatment on the hepatotoxicity and the cytochrome P-4 50-dependent enzyme system was examined in adult female rats. Administrations of betaine (100 or 1,000mg/kg/day, ip) to rats repeatedly for 4 or 9 days did not evoke hepatotoxic response as determined by increases in glutamic pyruvic transaminase(GPT) and glutamic oxaloacetic transaminase(GOT) activities measured 24 hours following the final dose of betaine. The activities of aminopyrine N-demethylase, p-nitroanisole O-demethylase and p-nitrophenol hydroxylase as well as the contents of cytochrome P-450 were determined in hepatic microsomes of rats treated with betaine(1,000mg/kg/day, ip) for 4 or 9 days. Repeated treatment of rats with betaine for a period of 4 days induced a marginal decrease in the contents of cytochrome P-450, but did not influence the activities of p-nitrophenol hydroxylase, p-nitroanisole O-demethylase, or aminopyrine N-demethylase. Extension of the betaine treatment to 9 consecutive days failed to alter the parameters for hepatic drug metabolizing activity determined in the present study. Since repeated large doses of betaine were demonstrated to be tolerated by rats without showing any toxicity or changes in drug metabolizing enzyme activities in the liver, this compound appears to be relatively safe to animals upon long-term ingestion.
