This study aimed to investigate the alterations in plasma antioxidant activity after the consumption of a single oral dose of curcumin, vitamin C, and E administered individually or in combination to (i) assess possible synergies or antagonism between the antioxidants and (ii) determine the optimal composition of the antioxidant mixture such that the duration of action is prolonged to beyond that of individual antioxidants. Each antioxidant was administered to male Sprague-Dawley rats, and blood samples were drawn at different time points up to 180 min to measure the plasma total antioxidant capacity (TAC). Five antioxidant compositions (M1-M5) were evaluated to assess the possible synergies or antagonisms among them and to determine the optimal composition of the antioxidant mixture. Blood samples were collected up to 360 min post-consumption. A single oral dose of individual antioxidants significantly increased the TAC values; however, the time to reach the peak TAC value varied. Among the 5 antioxidant compositions, M2 exhibited the highest and most prolonged antioxidant effect in plasma; this was greater than the proportional sum of the effects of the individual antioxidants in the composition. This result indicates a synergistic interaction among antioxidants in the optimal composition M2.

To investigate the re-treatment time of Microcotyle sebastis by oral administration of praziquantel, the residue levels of praziquantel in plasma of rockfish Sebastes schlegeli administered orally at a dose of 200 mg/kg B.W. were analyzed by reversed-phase HPLC, and the concentrations of praziquantel in the plasma were correlated with the extermination of M. sebastis. The absorption and depletion of praziquantel in the blood of rockfish were fast and the residual concentrations of praziquantel declined below $4\mu g/mL$ within 24 hr post treatment. Most of worms were exterminated within 3 hr after oral administration of praziquantel, however, a small number of M. sebastis were not killed by the treatment until end of the experiment. Considering fast drop of praziquantel in blood and extermination pattern of M. sebastis in the present results, retreatment at an interval of 9-12 hr would be effective for eradication of M. sebastis.

The selenium status of beef cattle in the southern part of Thailand and the selenium concentration of soil and herbage consumed by those animals were investigated. Samples were collected from three areas with different soil types, namely, sandy soil, peat soil and laterite soil. The selenium concentration of soil, herbage and blood plasma showed a similar tendency; the values of laterite soil were higher than those of the other two areas. However, the selenium concentration of herbage of each pasture was lower than the NRC requirement, and that of blood plasma was not in the sufficient level. These data suggested that beef cattle raised in these areas were in the chronic selenium deficiency. We concluded that selenium supplementation is needed for the increase of animal productivity in the southern part of Thailand.

Obesity is psychological and socioeconomic problems as well as health problems related to physical disease and disorder. The obesity epidemic, including a marked increase in the prevalence of obesity among pregnant women, represents a critical public health problem throughout the world. Gung-Gui-Tang (GGT), a prescription of traditional Korean medicine, has been used to treat dizziness due to loss of blood as well as static blood after childbirth. However, the therapeutic potential of GGT on postpartum obesity has not been fully elucidated in an experimental model. In our research, GGT inhibited the increases of body weight and adipose tissues in postpartum mice fed a high-fat diet. GGT also inhibited the elevations of plasma lipid profiles such as triglyceride, low-density lipoprotein cholesterol, total cholesterol, and glutamate pyruvate transaminase. Overall, these results provide evidence that GGT can help to inhibit postpartum obesity and open new perspective to recover the shape of mother into the moment of conception.

In this study, a basic research on artificial liver was performed for its application to people on the waiting list of liver transplant or patients with hepatic insufficiency. Artificial livers are generally classified into mechanic type, bioartificial type, and hybrid type. An extracorporeal circulation device was examined herein, which is indispensable in the application of an artificial liver, for its effectiveness in supporting the recovery of liver functions. Extracorporeal circulation system is a treatment and life-support system which sends out the patient's blood, removes toxicity by various methods, and then sends the blood back to the interior of the body. This study used an extracorporeal circulation system which enables the Plasma Perfusion by CVVH method, and applied the program of Bioateco corp. Animals with acute hepatic insufficiency were produced to apply the extracorporeal circulation device. As a result, their ammonia, bilirubin, SGOT, SGPT, and bile acid levels rose, confirming the liver function restoration in the experimental animals.

Sixteen holstein heifers were employed to study the effect of thermal stress on rectal temperature and mineral status of heifers around parturition during hot and cool weather. During the hot weather, rectal temperatures of the heifers measured at 08:30 and 15:30 h from 7 d prepartum to parturition were higher than those during the cool weather. Blood hematocrit and hemoglobin were not significantly different between the hot and cool weather, but at 2 and 1 wk prepartum, those during the hot weather were higher. Plasma Ca, inorganic P and Fe of the heifers during the hot weather were higher than those during the cool weather, but plasma Mg and Zn and serum alkaline phosphatase during the hot weather were lower. Colostral protein and Mg of heifers at parturition during the hot weather were lower than those during the cool weather, but colostral Ca, P, Fe and Zn were not affected by the weather.

Increased plasma insulin levels are often observed in exogenous insulin overdose patients. However, plasma insulin level may decrease with time. We report a case of low plasma insulin level hypoglycemia after insulin lispro overdose. The patient was a 37-year-old man with no previous medical history who suspected insulin lispro overdose. Upon arrival, his Glasgow coma scale was 3 points and his blood sugar level (BSL) was 24 mg/dl. We found five humalog-quick-pen (insulin lispro) in his bag. There was no elevation of glucose level, despite an initial 50 ml bolus of 50% glucose and 150 cc/hr of 10% dextrose continuous intravenous infusion. He also suffered from generalized tonic-clonic seizure, which was treated with lorazepam and phenytoin. We conducted endotracheal intubation, after which he was admitted to the intensive care unit (ICU). There were recurrent events of hypoglycemia below BSL<50 mg/dl after admission. We repeatedly infused 50 ml 50% glucose 10 times and administered 1 mg of glucagon two times. The plasma insulin level was 0.2 uU/ml on initial blood sampling and 0.2 uU/ml after 5 hours. After 13 hours, his BSL stabilized but his mental status had not recovered. Diffuse brain injury was observed upon magnetic resonance imaging (MRI) and severe diffuse cerebral dysfunction was found on electroencephalography (EEG). Despite 35 days of ICU care, he died from ventilator associated pneumonia.

The objective of the current study was to determine acute plasma stress responses in two size groups of juvenile Epinephelus akaara (average body weight: $8.4{\pm}2.1$ and $3.3{\pm}0.6g$; 150 and 120 days after hatch, respectively) exposed to abrupt salinity drops (from 34 practical salinity unit, PSU seawater to 18, 10 PSU (experiment 1) or 26, 18, 10 PSU (experiment 2), respectively). Plasma glucose, glutamic oxalate transaminase, glutamic pyruvate transaminase, red blood cell counts, and gill histology were determined during 72 h exposure. Significantly increased plasma glucose, glutamic oxalate transaminase levels, and red blood cell counts were observed in fish exposed to 18 or 10 PSU. Histological changes, such as hyperplasia and lifting of epithelium in the gill secondary lamellae, were also observed in fish exposed to 18 or 10 PSU at 72 h post-drop. E. akaara exposed to sudden salinity drops to 18 or 10 PSU still seems to undergo the primary adjustment phase before fish reaches a new homeostasis, whereas fish exposed to 26 PSU seems to mount osmotic changes. Therefore, the no observed adverse effect levels for 72 h acute salinity challenge was 26 PSU in our study, and salinity drop to 18 PSU and below can possibly cause acute adverse effect, in which fish could be vulnerable to additional stresses such as a temperature changes or handling stress.

Attempts were made to determine the effects of 5-Korean wild vegetabel consumptions on blood glucose leveles and orgen-energy metabolisms in streptozotocin-induced diabetic rats. The 5-Korean wild vegetables were : Cassia tora L.(C.t), Lycium chinese Mill(L.c), Trichosanthes kirilowii Max(T.k), Polygonatum odoratum var. Pluriflorum Ohwi(P.o) and Arctium lappa L(A.l). Sixty male Spargue-Dawley rats(160-220g) were induced diabetes mellitus by streptozotocin injection into the tail vein and were devided into 6 groups : a diabetic control and 5-experimental groups. All groups of the rats were fed on a AIN-76 diet, and the 5-experimental groups were fed with each wild vegetable (10%) for four weeks. An increased tendency in body weight of all the groups was observed and the tendency was more significant in L.c, T.k. and P.o. groups. The organ weight of liver and kidney were higher in L.c. and A.l. groups and lower in T.k. group which has shown the improvement from diabetes. Plasma glucose levels were markedly decreased from the 1st week in C.t, T.k. and P.o. groups and the tendency has lasted throughout the four weeks experimental period. The consumption of P.o. has decreased plasma cholesterol level while any significant difference was not seen in plasma protein levels from all the experimental groups. The level of plasma triglyceride was decreased in P.o. group and the levels of plasma free fatty acids were also significantly lower in P.o. and T.k. groups. The liver protein levels were significantly higher in P.o. and T.k. groups and these two groups also showed the negative or relatively small amount of urinary glucose excretion. The experimental group of T.k. has revealed the decreased level of muscles protein and the increased level of muscle glycogen. The 5-Korean wild vegetables contained dietary fiber and 9-analyzed minerals comparable to the ordinary use vegetables.
