Triplicate groups of fed and starved olive flounder, Paralichthys olivaceus (body weight: $119.8{\pm}17.46$ g), were examined over 42 days for physiological changes using hematological, biochemical, and non-specific immune parameters. No significant differences in concentrations of blood hemoglobin and hematocrit and plasma levels of total cholesterol, aspartate aminotransferase, alanine aminotransferase, glucose, and cortisol were detected between fed and starved groups at any sampling time throughout the experiment. In contrast, plasma total protein concentrations were significantly lower in starved fish than in fed fish from day 7 onwards. Moreover, plasma lysozyme concentrations were significantly higher in starved flounder from day 21 onwards. This result confirms that the response of olive flounder to short-term (less than about 1.5 months) starvation consists of a readjustment of metabolism rather than the activation of an alarm-stress response. The present results indicate that starvation does not significantly compromise the health status of fish despite food limitation.

BACKGROUND/OBJECTIVE: The aim of this study was to examine the effect of high dietary methionine (Met) consumption on plasma and hepatic oxidative stress and dyslipidemia in chronic ethanol fed rats. MATERIALS/METHODS: Male Wistar rats were fed control or ethanol-containing liquid diets supplemented without (E group) or with DL-Met at 0.6% (EM1 group) or 0.8% (EM2 group) for five weeks. Plasma aminothiols, lipids, malondialdehyde (MDA), alanine aminotransferase (ALT), and aspartate aminotransferase were measured. Hepatic folate, S-adenosylmethionine (SAM), and S-adenosylhomocysteine (SAH) were measured. RESULTS: DL-Met supplementation was found to increase plasma levels of homocysteine (Hcy), triglyceride (TG), total cholesterol (TC), and MDA compared to rats fed ethanol alone and decrease plasma ALT. However, DL-Met supplementation did not significantly change plasma levels of HDL-cholesterol, cysteine, cysteinylglycine, and glutathione. In addition, DL-Met supplementation increased hepatic levels of folate, SAM, SAH, and SAM:SAH ratio. Our data showed that DL-Met supplementation can increase plasma oxidative stress and atherogenic effects by elevating plasma Hcy, TG, and TC in ethanol-fed rats. CONCLUSION: The present results demonstrate that Met supplementation increases plasma oxidative stress and atherogenic effects by inducing dyslipidemia and hyperhomocysteinemia in ethanol-fed rats.

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.

To evaluate the impact of parathion on aquatic organisms, a freshwater bagrid catfish (Pseudobagrus fulvidraco) was exposed to sublethal concentrations $(63,\;95,\;190\;and\;380\;{\mu}g/L)$ of parathion, organophosphorus pesticide for 30 days. Glucose level in the serum of the bagrid catfish was significantly increased than that of control groups in the $190\;{\mu}g/L$ concentration at 30 days and in the $380\;{\mu}g/L$ concentration after 10 days. Bilirubin level was significantly increased in the $190\;{\mu}g/L$ concentration at the end of the experiment. After 10 days, a significant differences of lactate dehydrogenase (LDH) and alkaline phosphatase (ALP) activity increased in the ${\geq}190\;{\mu}g/L$ and $380\;{\mu}g/L$ groups. Though cholesterol concentration was stable, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activities in serum were significantly reduced in the $190\;{\mu}g/L$ at 10 days and in the $380\;{\mu}g/L$ concentration at the end of the experiment. In conclusion, if P. fulvidraco was chronically exposed to ${\geq}190\;{\mu}g/L$ concentration of parathion, the hematological changes may be induced due to the stress response.

This study the effects of Cu exposure on biochemical factors in the hemolymph and hepatopancreas of the abalone $Haliotis$ $discus$ $hannai$. Abalone were exposed to 0, 5, 10, 20 and 40 ${\mu}g/L$ Cu for 4 weeks. The calcium concentrations in hemolymph were decreased significantly on exposure to 20 and 40 ${\mu}g/L$ Cu after 2 weeks. The aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP) activities in abalone hemolymph were markedly elevated after exposure to 40 ${\mu}g/L$ Cu for 4 weeks. The hepatopancreas superoxide dismutase (SOD) and catalase (CAT) activities were also significantly increased by exposure to 20 ${\mu}g/L$ Cu for 4 weeks. These biochemical factors may represent a convenient method of monitoring heavy metal pollution in coastal areas. From these results, we conclude that a high copper concentration (40 ${\mu}g/L$) in water may curtail hemolymph homeostasis and anti-oxidative reactions in abalone.

Nine biochemical characteristics of female Oncorhynchus keta subpopulations that migrate to three streams (Namdaechun, Myeongpachun, Oshipchun) in Gangwon, Korea, were evaluated during November 2006: aspartate aminotransferase, alanine aminotransferase, creatine kinase, triglyceride, cholesterol, glucose, hemoglobin, and urea in the blood and RNA/DNA in muscle. The three subpopulations were identical morphologically, but differed in their biochemical characteristics. The RNA/DNA ratio could be useful for distinguishing the subpopulations. RNA/DNA ratios of the Namdaechun and the Myeongpachun and Oshipchun subpopulations were $3.52{\pm}0.7$ and $2.9{\pm}0.7$ and $2.4{\pm}0.8$, respectively. The difference was statistically significant (P<0.05). By contrast, the blood parameters were somewhat ambiguous.

Vitamin B-6 nutrition has been shown to be inadequate in many population groups including pregnant and lactating women, and in infants. Vitamin B-6 intake was measured in 98 pregnant mothers and a total of 172 cord blood samples of their and other new born infants were analyzed for erythrocyte alanine aminotransferase(EALAT) activities with or without the addition of pyridoxal-5-phosphate to assess vitamin B-6 status of the infants. The average daily vitamin B-6 intake of the pregnant mothers was 1.79mg$\pm$0.88(81.4% of the Recommended Dietary Allowances ; RDA) and vitamin B-6 to protein intake ration was 0.017mg vitamin B-6/g protein. Thirty-eight percent of the pregnant women consumed diets which provided less than the RDA for vitamin B-6 during pregnancy. Seventy-two percent of the dietary pyridoxine intake was provided by the plant food source whose bioavailability was reported to be lower when compared to that of the animal food. The average activity coefficient(AC) values of the cord blood EALAT was 1.41$\pm$0.11, and 32% of the blood samples had EALATAC values greater than 1.25, suggesting that vitamin B-6 status of the newborns might be less than adequate.

Korean red ginseng is known to regulate the immune system and help the body struggle infection and disease. Cadmium is widely distributed in the environment due to its use in industry. Exposure to cadmium is problematic causing organ dysfunction. This study was conducted to evaluate the protective effect of Korean red ginseng extract (RGE) against cadmium-induced hepatotoxicity in rats. In experiments, animals were orally administrated with RGE (25, 50 mg/kg) for 7 d and then intravenously injected with cadmium ($CdCl_2$, 4 mg/kg) to induce acute hepatotoxicity. Cadmium caused the elevated levels of alanine aminotransferase, aspartate aminotransferase, and lactate dehydrogenase in serum. In contrast, pretreatment with RGE significantly reduced those serum indexes related with liver damage. In histopathological analysis, RGE decreased the centrilobular necrosis around central veins and the peripheral hemorrhage around portal triads. Moreover, RGE restored the deficit in hepatic glutathione level resulting from cadmium treatment. RGE also inhibited the increase in the expression of Bad, a representative apoptosis marker protein, induced by cadmium treatment. Collectively, these results demonstrate that RGE can reduce the cadmium-induced hepatic toxicity, partly via anti-oxidative and anti-apoptotic process.

Lindera erythrocarpa Makino (LE) is widely distributed on Jeju Island, where it has been used for various traditional therapies. Effects of a crude extract of LE were examined in rats with obesity induced by a high-fat diet (HFD). Anti-obesity effects were followed in rats receiving orally administered vehicle, 100mg/kg extract, or 250 mg/kg LE extract, for 56 days. LE extract (250 mg/kg) suppressed increases in body weight and epididymal fat, with amelioration of fatty changes in the liver. Additionally, serum levels of alanine aminotransferase, aspartate aminotransferase, and total cholesterol were significantly decreased compared with those of vehicle-treated groups (p < 0.05). These results suggest that oral administration of LE extract reduced rat obesity induced by HFD, possibly through the reduction of fat accumulation.
