Serum biochemical values were measured in blood samples collected from 8 fasted stags from both jugular and femoral veins at 18-day intervals during antler growth. Samples were analyzed for blood substrate, enzyme activity values, minerals and electrolyte. There were no significant differences in total protein, albumin, urea, creatinine, triglyceride, glucose or cholesterol concentration between veins or sampling dates. However, total-bilirubin concentration in the jugular vein on the casting date was three times higher than on the other sampling dates (p<0.05). There were no significant differences in alkaline phosphatase, aspartate aminotransferase, and alanine aminotransferase with progressing antler growth. The highest level of alkaline phosphatase concentration was on day 55 after casting. There were no significant differences in inorganic phosphorus, sodium and chloride concentration between jugular and femoral samples. Calcium concentration was significantly higher in the femoral vein on the cutting date (55 day) than in the jugular vein (p<0.05). There were few changes in serum biochemical values. However, some electrolytes and minerals had differences during antler growth. It is suggested that despite such a big event as antler growth, blood biochemical values are not variable if feeding conditions are consistently maintained as was the case in this study.

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.

The hepato-protective activity of the GODEX (Hepadif-s capsule) has been studied in the rats against $CCl_4$-ethanol induced liver toxicity. The rats were oral1y treated with $CCl_4$ (corn oil/ $CCl_4$ 1:1, 1 mg/kg). And one week passes, $CCl_4$(0.4 mg/kg) administered two times a week for 7 weeks. The drugs have been administered every two days for 4 weeks after $CCl_4$ injection. The experimental groups have consisted of the GODEX (250 mg/kg), Hepadif (200 mg/kg), DDB complex (DDB 50 mg/kg and garlic oil powder 50 mg/kg), DDB (50 mg/kg), and vehicle control respectively. There was a significant decrement on the serum level of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and total bilirubin in all treated groups. Specially, ALT level of GODEX and Hepadif only treated groups was decreased c1early. Also, serum albumin level was significantly enhanced in GODEX treated group compared with control and DDB treated groups. In histological results, hepatocellular vacuolar degeneration, lobular restructure and necrosis of bile duct were severely showed in control. But other treated groups showed centerilobular degeneration and mild hyper-plasia. Hepadif or DDB has a effects of the recovery on serum parameters and structure ill liver injury. When it was compared GODEX to Hepadif alone or DDB complex or DDB, it suggested to have the best activity of the liver recovery.

The effects of Opuntia ficus-indica (OF) administration on the biochemical parameters of function in liver tissue and serum of $CCl_4$ treated rats were investigated. Opuntia ficus-indica (200 mg/kg) was administered into rats intraperitoneally for two weeks. $3.3m\ell$ of $CCl_4$$_4$ (50% $CCl_4$ : Olive oil = 1 : 1) was treated to rats on the 14th day and 15th day and they were operated on 15th day. We examined the antioxidative enzymatic activity by measuring the level of AST (Aspartate aminotransferase), ALT (Alanine aminotransferase), GSH (Glutathione reduced form), GSSG (Glutathione oxidezed form), GPx (GSH-peroxidase), SOD (Superoxide dismutase) and CAT (Catalase) in serum and liver tissue of rats. OFC administered group showed 24.8% of inhibitory effect in AST activity compared to $CCl_4$ -treated abnormal group (CTA). ALT level of OF administered group was decreased by 60.7% to the level of CTA. GSH, GSSG and GPx of OFC administered group were significantly higher than those of CTA group. SOD and CAT in OFC administered group were increased by 28.3% and by 16.9% respectively compared to those of CTA group.

Exposure indices are important tools which enable scientists to reliably predict and detect exposures to xenobiotics and resultant cell injury. Since the de novo synthesis of stress proteins can be detected early after exposure to some agents, analysis of toxicant-induced changes in gene expression, i.e. alterations in patterns of protein synthesis, may be useful to develop as biomarkers of exposure and toxicity. The acute and chronic effects of cadmium(Cd, $CdCl_2$ 20 mg/kg) on Wistar male rats were evaluated concerning cadmium contents, tissues enzyme activity, HSP expression. The results of the study were as follows: 1. Less cadmium was absorbed through the digestive tracts, but the ratio of contents in renal to hepatic cadmium was higher at 8 weeks after treatment. 2. ALT(alanine aminotransferase), AST(aspartate aminotransferase), glucose, BUN(blood urea nitrogen), creatinine, the key indices of the clinical changes in hepatic and renal function were significantly changed by the cadmium treatment after 1 week in liver, after 4 weeks in kidney. 3. Enhanced synthesis of 70 KDa relative molecular mass proteins were detected in 2 hours after cadmium exposure, with maximum activity occurring at 8~48 hours. Induction of $HSP_{70}$ was evident at proximal tubules and glomeruli in kidney. Testicular cells produced enough HSP to be detected normally. From the above results, it could be concluded that $HSP_{70}$ induction by the cadmium treatment was a rapid reaction to indicate the exposure of xenobiotics.

We investigated the effects of water temperature on physiological parameters in the chicken grunt Parapristipoma trilineatum. At high temperature, the aspartate aminotransferase (AST) and the alanine aminotransferase (ALT) levels were increased, suggesting that high temperature induced hepatic damage. In addition, total protein (TP) was high at high water temperatures, which were considered stressful in the breeding environment. At high water temperatures, triglycerides (TG) were low due to increased metabolic activity, which decreased the blood TG levels as TG were used as an energy source. There was no significant difference in the plasma osmolality or the blood ion concentrations with water temperature. In generally, lysozyme, a factor in innate immunity, increased with water temperature. However, lysozyme activity tended to decrease with increasing water temperature, but the difference was not significant. These results suggested that the decrease of biophylaxis at high temperature was affect the growth or survival of the population.

The present study was carried out to investigate the serum enzyme activities of racehorses. The enzymes investigated were aspartate and alanine aminotransferase (GOT, GPT), ${\gamma}$-glutamyl transpeptidase(${\gamma}$-GTP), Lactic dehydrogenase(LDH), creatine phosphokinase(CPK), and alkaline phosphatase(ALP). Animals used were 30 healthy racehorses(♀17, ♂13) average weighing 435kg and were from 2 to 8 years of age. LDH activity was progressively decreased with age and next in the order of GOT and CPK activities. GOT and ${\gamma}$-GPT activities were not changed with age but ALP activity tended to be decreased wish age. Activities of GOT, GPT, ${\gamma}$-GTP and ALP were higher in female than in male. There was no difference in CPK activity by sex, and no difference was found out among breeds.

The purpose of this study was to investigate the effects of a butanol fraction of fraction of Alisma canaliculatum All. Braun et Bouche (Ac), and of selenium (Se), on plasma gllucose and lipid levee in streptozotocin (STD-induced diabetic rats. Male Sprague-Dawley rats, fed the AIN-93 recommended diet, were divided into five groups: a non-diabetic control group (no STZ treatment), and four 572-induced diabetic groups which consisted of a diabetic-control group, an Ac-treated group, an Ac-Se treated group, and a Se-treated group. Diabetes was induced in the rats by an injection of STZ into the tail vein at a dose of 45 mg/kg body weight. The butanol (BuOH) fraction of Ac was orally administered at a rate of 400 mg/kg body weight for 21 days to both the Ac and Ac-Se groups. The supplementation of selenium in the Se and Ac-Se groups was achieved by adding (freshly, every day) 2 mg of Se as Na$_2$SeO$_3$ per kg of feed. The rats'body weights and hematocrit (Hct) levels were measured, along with plasma levels of glucose, insulin, cholesterol, HDL-cholesterol, triglyceride (TG), and free fatty acids (FFA). Aminotransferase activities were also analyzed. The non-diabetic rats gained weight, while the diabetic rats lost weight - except in the Ac-Se group, which maintained their initial weight. The blood glucose levels of the Ac group and the Se group were significantly lower than for the diabetic-control group. The plasma triglyceride levels were lowered when both Ac and Se were administered to diabetic rats. The concentrations of plasma FFA in the Ac-Se group were significantly lower compared with the diabetic-control group. Plasma cholesterol levels and alanine aminotransferase activity in the Ac, Ac-Se, and Se groups were significantly lower when compared with the diabetic-control group. Aspartate aminotransferase activity was significantly lower in the Se group compared to the other diabetic groups. These data show that treatment with a butanol fraction of Ac in combination with Se has no synergistic effect. Plasma glucose levels tended to be low when Se was administered to diabetic rats. Supplementation of Se in diabetic rats did not elicit a significant increase in plasma insulin levels or result in hypolipemic effects.

The purpose of this study was to investigate the effect of chloroform(CHC1$_3$) fraction of Alisma canaliculatum All. Braun et Bouche(Ac) with selenium(Se) on the plasma glucose and lipid levels in streptozotocin(STZ)-induced diabetic rats. Male Sprague-Dawley rats were divided into five groups. The normal and diabetic rats were separated into four groups: the STZ-control group, the Ac group, the Ac-Se group and the Se group. Diabetes was induced in the male rats by an injection of STZ into the tail vein at a dose of 45 mg/kg. The CHCl$_3$fraction of Ac(250 mg/kg) was administered orally for 14 days. The supplementation was achieved with the AIN-93 recommended diet by adding 2 mg/kg diet of selenium as Na$_2$SeO$_3$. which was prepared freshly everyday. The body weight, hematocrit(Hct), glucose, insulin, cholesterol, HDL-cholesterol, triglyceride(TG) and free fatty acids(FFA) concentrations in plasma were measured. The aminotransferase activities were also analyzed. The changes of body weight in the experimental groups were not significantly different from that of the STZ-control group, but diabetes hyperphagia accompanied changes with body weight loss in Ac-Se group. The levels of Plasma cholesterol were not significantly different among the experimental groups. The concentrations of FFA in the Ac-Se group increased significantly compared with the STZ-control group. The effect of Se alone significantly increased aspartate aminotransferase activity and alanine aminotransferase activity. The results showed that the treatment of CHCl$_3$fraction of Ac in combination with Se has no synergistic effect. There was a tendency for the plasma glucose levels to decrease when Se was administered into diabetic rats. Supplementation of Se in diabetic rats did not elicit a significant increase in plasma insulin levels and exhibited hypotriglyceridemic effect.

To apply the serum xanthine oxidase (XO) determining for the index of the toluene intoxication, the serum XO activity was compared with the other parameters, the activities of serum alanine aminotransferase(ALT), aspartate aminotransferase(AST), 5'-nucleotidase(5'-NT), alkaline phosphatase(ALP), guanase(GDA) and $\gamma$-gIutamyl transpeptidase(T-GTP). Concomitantly, the cause of increased level of serum XO was clarified in the present experimental conditions. Although the other serum enzyme activities, ALT, AST, 5'-NT, ALP, GDA and $\gamma$-GTP were respectively not found to be different between control group and toluene-treated group, the serum XO activity in toluene-treated group showed the higher levels than that in the control group. These suggested that the determination of serum XO activity could be used for monitoring the intoxication of toluene. On the other hand, the activities of XO both in the serum and liver were higher in toluene-treated or benzaldehyde-treated rats than those in each control group. In the pooled liver XO from each group, toluene-treated or benzaldehyde-treated group showed the higher $V_{max}$ value than the control group, whereas no changes were observed in liver XO activities between the control liver specimen and that preincubated with bertzaldehyde in vitro. The present results indicate that the increased level of XO in toluene-treated rats is due to the result of enzyme protein induction in liver cell by the benzaldehyde metabolized from toluene. All the more, the benzaldehyde may be acted as a substrate for XO, since the benzaldehyde induced the increased activity of both liver and serum XO, and no changes were found in purine catabolite, uric acid in serum or urine and liver purine catabolizing enzymes, adenosine deaminase, GDA, uricuse except XO in toluene-treated rats.
