The study was carried out to examine the anti-obesity effects of 40% ethanol extract from green tea seed (GS) and quantitative determination of caffeine as its major compound. The specificity was satisfied with retention time and UV spectrum by analysis of caffeine using HPLC and comparison with standard compound. It showed a high linearity in the calibration curve with a coefficient of correlation (R²) of 0.9974. The amount of caffeine in GS was about 4.649 mg/g (0.465%) in the three times analysis, and relative standard deviation (RSD) was less than 0.452% by the validated method. The anti-obesity effects of GS were evaluated by using Oil Red O staining in 3T3-L1 adipocytes and body weight, visceral fat and lipid profiles in high fat diet (HFD)-induced C57BL/6 obese mice. Our results indicated that treatment with GS dose-dependently decreased lipid accumulation contents (p<0.001). Moreover, after oral administration for 30 days feeding with HFD-induced obses mice, GS (100 and 300 mg/kg/day) produced a significant decrease in serum total cholesterol (TC), glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT) and visceral fat. Thus, the result of this study indicate that the GS may be a useful resource for the management of obesity.

This experiment was carried out in order to elucidate the effect of NaCl(0.85%) acclimation on congestion symptoms in central venous sinuses(CVS) of gill filaments and on the alteration of blood constituents in cultured eels for 1, 2, 3, 4, 5, 6 and 7days after handling stress. After giving a handling stress on eels, the frequency of gill congestion was about 90%. It gradually decreased to 40% on the 3rd day, then increased to 60% on the 7th day in NaCl(0.85%) acclimation. The values of haematocrit(Ht), methemoglobin(Met-Hb), glucose (GLU), calcium($Ca^{++}$), lactic dehydrogenase(LDH), glutamic pyruvic transaminase (GPT) and glutamic oxaloacetic transaminase(GOT) were lower than those of the control, whereas magnesium($Mg^{++}$) and haemoglobin(Hb) were higher than the control. However total protein(Tp) and albumin (ALB) levels similar to the control. When the fish after giving a handling stress were cultured in NaCl-free water as a control, the frequency of gill congestion and the value of blood components showed a similar pattern to that obtained from the NaCl acclimated experiments. However, in the early period(1-3day) after handling stress, NaCl acclimating slightly helped the natural tendancy of recovery. These results suggest that the frequency of gill congestion is not always reduced over the whole period of NaCl acclimation. However, the acclimation to NaCl solution may be a somewhat useful therapy for the gill congestion in stressed eels.

This study was conducted to investigate the dietary effects of germinated and fermented (with Monascus pupureus) soybean screenings (GFS) on growth performance and meat quality in broiler chicken. A total of 750 1-day-old Ross ${\times}$ Ross male broiler chicks were randomly allocated into five groups (five replications with 30 birds each) and fed experimental diets for 5 wks as follows: Group 1, negative-control (antibiotics-free diet); Group 2, positive-control (negative-control with 10 ppm of Avilamycin); Group 3, negative-control with 0.3% GFS; Group 4, negative-control with 0.5% GFS; Group 5, negative-control with 1% GFS. The final body weight of each group fed a diet containing 1% GFS was significantly higher than that of the negative-control group. The feed conversion ratios of all groups fed diets containing GFS and the positivecontrol group were significantly improved compared to the negative-control group during the whole period (p<0.05). The relative weights of various organs along with the activities of serum glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) were not influenced by the dietary treatments. The levels of total serum cholesterol in groups fed diets containing 0.5% and 1% GFS were more significantly lowered compared to those of the control groups without GFS (p<0.05). There were no significant differences in the cecal microflora profiles among the groups. Further, the dietary treatments did not influence the physico-chemical properties of the edible meat, including the shear force, pH, meat color (CIE $L^*$, $a^*$ and $b^*$), and content of malondialdehyde (MDA). Cooking loss of breast muscle in the groups fed GFS was significantly lowered compared to that of the negative control group (p<0.05). These results indicate that dietary GFS could improve growth performance in broiler chicken and may affect meat quality in some instances.

Objectives: This study was designed to investigate the effect of Gami-cheongpyesagan-tang extract (GCST) on high fat diet-induced obesity in rats. Methods: The mice were divided into six groups; normal diet control, high fat diet control (HFD), HFD+GCST administrated group (100, 200, and 400 mg/kg) and olistat-admistrated group. Obesity was induced by high fat diet (45%) for 7 weeks in mice, and GCST was administrated orally every day for 7 weeks. The body weight, food intake, and serological markers such as total cholesterol, triglyceride, lipid contents, leptin, adiponectin and glutamic oxaloacetic transaminase/glutamic pyruvic transaminase were measured in mice. The mRNA expression of obese-associating genes such as sterol regulatory element-binding protein (SREBP)-1c, fatty acid synthase (FAS), stearoyl-CaP desaturase (SCD-1), peroxisome proliferator-activated receptor $(PPAR)-{\alpha}$, COA oxidase (ACO), and carnitine palmitoyltransferase ($CPT-1{\alpha}$) was analyzed by reverse transcription polymerase chain reaction. Results: The administration of GCST at 400 mg/kg, significantly reduced the increase of body weight and food intake as well as food efficiency compared to HFD group. GCST decreased the serum levels of triglyceride, total cholesterol, low-density lipoprotein-cholesterol, leptin in HFD control group and inhibited lipid accumulation in liver and adipose tissues, but did not increase high-density lipoprotein-cholesterol. In the liver tissues of GCST administrated HFD group, the mRNA levels of SREBP-1c, FAS and SCD-1 were decreased and the mRNA levels of $PPAR-{\alpha}$, ACO, and $CPT-1{\alpha}$ were increased. Conclusions: These results indicate that GCST could improve high fat diet induced obesity through inhibiting the hyperlipidemia in fatty Liver. It suggest that GCST may be used clinically for declining the accumultion of body fat with hyperlipidemia.

Objectives: This study investigated the effects of Scutellariae Radix extract (SRE) on lipids metabolism, oxidation and the production of pro-inflammatory cytokines in rats fed highly oxidized fat. Methods: To induce obesity, male Sprague‐Dawley rats were fed a highly oxidized fat diet for 10 weeks. SRE at 100 mg/kg were administered orally to obesity-induced rats for 6 weeks, and their lipid metabolism, oxidation and production of pro-inflammatory cytokines were examined. Results: The concentrations of free fatty acid, triglyceride, total cholesterol, and low density lipoprotein-cholesterol in plasma decreased in SRE-treated groups, although the difference was not significant between control and SRE-treated groups, while that of high density lipoprotein-cholesterol significantly increased in SRE group. The concentrations of total cholesterol and triglyceride in the liver were tended to decrease in SRE-treated group. The concentrations of thiobarbituric acid in plasma and liver were lower in SRE group than in control group. The levels of glutamic oxaloacetic transaminase and glutamic pyruvic transaminase in plasma were decreased in SRE group. Activities of glutathione peroxidase, superoxide dismutase, and catalase in liver were tended to increase in the SRE group. The plasma concentrations of interleukin $(IL)-1{\beta}$, tumor necrosis factor $(TNF)-{\alpha}$ and IL-6 were lower in SRE group than in control group, while that of IL-10 was higher. The liver concentrations of $IL-1{\beta}$, $TNF-{\alpha}$, and IL-6 were tended to decrease while that of IL-10 tended to increase in SRE group. Conclusions: Finally SRE could be used in the production of nutraceuticals for lowering lipids and exerting anti-oxidation and anti-inflammatory effects in obesity rats fed highly oxidized rat.

On 11-year-old female mixed-breed dog with chief complaints of existence of abdominal enlargement and anorexia was referred to the veterynary teaching hospital of Chungnam National University. The dog was diagnosed into cholangiocarcinoma by the result of the histopathological observation. The results observed are summarized as follows: The clinical signs were abdominal enlargement, anorexia, dyspnea and depression. There were marked increase in serum glutamic pyruvic transaminase(GPT), serum glutamic oxaloacetic transaminase(GOT), lactic dehydrogenase(LDH) and blood urea nitrogen(BUN). Serum total protein and albumin were slightly below normal. In gross finding, the liver was enlarged and friable with numerous white, cauliflower-like nodules over the surface and composed on cysts from 3 to 4 cm in diameter. The cystic lesions contained a yellow gelatinous material. Anatomically, this neoplasm was classified as intrahepatic bile duct carcinoma. Histologically, this neoplasm was combined tubular carcinoma with bile duct cystadenocarcinoma. The former were characterized by tubular structures lined by anaplastic cuboidal or columnar cells with diffuse fibrous stroma, and the latter by multiple cystic structures lined by simple and stratified cuboidal or columnar cells.

In order to investigate the liver damage and hepatic protective systems in cadmium(Dd) administered rats, five different levels of Cd were injected intraperitoneally to male rats of sprague-Dawley strains weighing $250{\pm}15g.$ Levels of daily Cd administration were 0(control), 0.625(A), 1.25(B), 2.5(C) and 5mg(D)/kg of body weight and single inhection per day was done for consecutive two days. With increasing Cd dosed, serum glutamic oxaloacetic transaminase, glutamic pyruvic transaminase and alkaline phosphatase activities were increased. And at the same time, hepatic reduced glutathione contents were decreased, whereas the levels of oxidized form were increased. Liver lipid peroxide levels of A, B, C and D groups were 1.1, 1.5, 1.8 activities and vitamin E contents were progressively reduced in accordance with the increase in Cd dose. However, liver superoxide dismutase activities were not different between control and A group although it was higher in B and lower in C and D groups compared with control.

This study investigated the production of insoluble dietary fiber using forest waste and the dietary effect of manufactured insoluble fiber on physiological function in rat fed high cholesterol duets. Insoluble dietary fiber was prepared from the wood chips of oak (Quercus mongolica). The best condition for steam-explosion treatment for the preparation of insonuble dietary fiber was 25 kg/cm$^3$pressure for 6 minutes. In the chemical analysis of insoluble dietary fiber pretreated by 1% sodium hydroxide solution with steam-exploded wood, $\alpha$-cellulose content was 61.7% in the insoluble dietary fiber which contained 7.6% residual lignin. In order to compare insoluble dietary fiber with commercial $\alpha$-cellulose of physiological function, Sprague-Dawley male rats weighing 100$\pm$10 g were randomly assigned to one normal diet and five high cholesterol diet containing 1% cholesterol. The high cholesterol diet groups were classified as fiber free diet (FF group), 5% commercial $\alpha$-cellulose diet (5C group), 10% commercial $\alpha$-cellulose (l0C group), 5% insoluble dietary fiber dict (5M group), and 10% insoluble dietary fiber (10M group). The rats were fed ad libidum for 4 weeks. Food intake, weights gain, and food efficiency ratio in high cholesterol groups were higher than those of normal group, but there were no significant differences between the experimental groups. There were not any significant differences in the weights of livers, kidneys and small intestine of insoluble dietary fiber supplemented groups, but weight of cecum in all insolube dietary fiber group were significantly higher than those of FF group. A gstrointestinal transit time was decreased by supplementation of insoluble dietary fiber. Weight and water contents of feces in the insoluble dietary fiber supplemented groups were significantly higher than those of the FF group. There were not any significant differences in the activities of the glutamic pyruvic transaminase (GPT) and glutamic oxaloacetic transaminase (GOT) between the experimental groups. In conclusion, the manufactured insoluble dietary fiber and commercial insoluble fiber have the same physiological effects. The preparation method of the insoluble dietary fiber from the oak chips suited its purpose.

The present study was conducted to investigate the effects of dietary supplemental dry powder of Rehmannia radix (RR) root on the growth performance and physiological status of broiler chicks. The treatments consisted of corn-soybean meal control diet, and RR 0.5, 1, and 2％ diets. A total of 160 Arbor Acre male broiler chicks were randomly allotted to 16 pens ; four pens per treatment and 10 birds per pen. The growth performance, feed intake and carcass weight did not show any differences among the treatment groups, but feed conversion was significantly lower (P< 0.05) in RR 1％ group than that of the control group. The muscle color was lighter (P < 0.05) in RR lof group than those of the other treatment groups. The blood concentrations of protein, glutamic-oxaloacetic-transaminase (GOT) and glutamic- pyruvic-transaminase (GPT) were not different (P > 0.05) among the treatment groups, but the blood total cholesterol content was significantly decreased (P < 0.05) in RR 2％ group than those the other treatment groups. The blood concentration of sugar was lower (P <0.05) in RR 2％ group than those of the other treatment groups, and hemoglobin concentration was decreased (P <0.05) by addition RR. Crude fat content of thigh muscle was higher in RR 1％ group than those of the other treatment groups, and bone hardness of broiler chicks fed RR was higher (P < 0.05) than that of the control group. The saturated fatty acid content of the thigh muscle tende to be high in control and RR 0.5％ groups, and unsaturated fatty acid content tende to be high in RR 1 and 2％ groups than those of the other treatment groups
