This study was conducted to investigate the effects of modification of a herbal recipe(Herb $Mix^{(R)}$) on the growth of pullet and laying performance of hens. The formula of Herb $Mix^{(R)}$, a mixture of Rehmannia glutinosa, Angelica gigas, Discorea japonica, Glycyrrhiza uralensis, Schisandra chinensis and Ligusticum jeholense, was modified in mixing ratio. A total of 1,120 pullets(Hy-Line Brown) of 14 wks old were assigned to seven treatments; control, Herb $Mix^{(R)}$(HM), R. glutinosa fortified HM, A. gigas fortified HM, D. japonica fortified HM, G. uralensis fortified HM, S. chinensis fortified HM, L. jeholense fortified HM and Flavomycin supplemented diet. Each treatment had 8 replicates of 20 birds each housed in 2 birds cages. Body weight at 10% egg production was significantly(P<0.05) influenced by treatments. Birds fed A. gigas fortified HM diet were heaviest followed by L. jeholense fortified HM, HM-original and D. japonica fortified HM, Flavomycin supplemented diet and R. glutinosa while those fed control diet were lightest. Also, age reaching 50% egg production and peak production was earliest in A. gigas fortified HM and latest in the control. Egg production, feed intake, feed conversion and egg weight were significantly influenced by treatments. Significant improvement in egg production and feed intake was shown in A. gigas fortified HM treatment. Feed conversion ratio was lowest in antibiotic(Flavomycin) treatment and egg weight was heaviest in L. jeholense fortified HM treatment. There were no significant differences among treatments in intestinal microflora but cfu of Cl. perfringnes and E. coli tended to be lower in HM treatments than the control. Among the leucocytes of blood, the HM treatments were lower than the control in counts of white blood cell and heterophils. It was concluded that modification of Herb $Mix^{(R)}$ fortifying with A. gigas, D. japonica and L. jeholense significantly influence growth and laying performance of birds.

The purpose of this study was to examine the effect of Allium hookeri (AH) root on hepatic antioxidative enzyme contents in streptozotocin (STZ)-induced rats. Diabetes mellitus was induced in male Sprague-Dawley rats through injection of STZ dissolved in citrate buffer into tail veins at a dose of 45 mg/kg body weight. Sprague-Dawley rats were fed an AIN-93 recommended diet, and the experimental groups were fed a modified diet containing 5% and 10% of AH root powder for 4 weeks. The experimental groups were divided into four groups: a normal control (N-control), STZ-control, STZ-AH 5%, and STZ-AH 10% supplemented groups. The STZ-AH 5% group showed a significant increase in liver glycogen compared to the STZ-control group. Muscle glycogen and liver protein contents significantly increased in the AH-supplemented groups compared to the STZ-control group. The liver malondialdehyde content of the AH-supplemented group was significantly lower than that of the STZ-control group. Xanthine oxidase content was significantly reduced in all experimental groups. Glutathione-S-transferase content was significantly elevated in the AH-treated groups compared to the STZ-control group. Superoxide dismutase content was not significantly different among the experimental groups. Catalase content was significantly higher in the STZ-AH 10% group compared to the STZ-control group. These results show that supplementation with AH root may be useful for diabetic therapy and damage from oxidative stress.

This study was performed to investigate the effect of water extracts from Namhae special crops (NSC) on improved serum lipid composition using rats fed a 1% cholesterol diet for 4 weeks. Male Wister rats (200-210 g) were divided into six groups: Normal cholesterol diet group (Normal), 1% cholesterol diet group (Control), 1% cholesterol and NSC water extract powder supplemented groups, including, turmeric (Tu-EP), cactus (Ba-EP), aloe vera (Al-EP) and asparagus (As-EP). No significant differences were observed for food intake or body weight gain between the control and experimental groups. However, food efficiency ratio (FER) was the lowest in the As-EP group. The serum levels of total cholesterol and triglycerides in the NSC water powder extract supplement groups were lower than those in the control group. The serum high density lipoprotein (HDL)-cholesterol content in the Tu-EP group was higher than that in the other experimental groups. Very low density lipoprotein (VLDL)-cholesterol content in the As-EP group was similar to that in normal group. Furthermore, the VLDL content in the Al-EP group was lower than that in the normal group. Serum antioxidant activity by TBARS level and DPPH radical scavenging were significantly higher in the Ba-EP group than that in the control group. Hepatic total cholesterol and lipid content in the Al-EP group decreased significantly compared to that in the control group. These results suggest that the NSC water extract may reduce serum cholesterol and prevent oxidative stress by stimulating antioxidative systems in rats fed a 1% cholesterol diet.

The liver is the major target of ethanol toxicity and oxidative stress plays a role in development of alcoholic liver disease. This study was performed to investigate the effects of green tea extracts (GTE) on acute ethanol-induced hepatotoxicity in rats. Experimental animals were divided into 4 groups, control, GTE, ethanol, and GTE+ethanol treatment, with 5 rats in each group. Ethanol (6 g/kg body weight (BW)) and GTE (200 mg/kg BW) were treated by gavage. At 1 hour, 3 hours and 20 days (6 g/kg BW every 2 days for total 10 doses) after ethanol and/or GTE treatments, animals were killed; hepatic tumor necrosis factor-alpha (TNF-$\alpha$) and glutathione level, serum aspartate aminotransferase (AST), serum alanine aminotransferase (ALT), hepatic antioxidant enzymes (SOD, CAT, GPx) activities and hepatic thiobarbituric acid reactive substances (TBARS) were measured. At 1 hour and 3 hours, hepatic TNF-$\alpha$ levels were increased significantly in ethanol group and ethanol+GTE group but that levels was significantly lower in ethanol+GTE group compared with ethanol group. Hepatic glutathione level was decreased by ethanol treatment but GTE prevented the ethanol-induced glutathione decrement. The levels of liver marker enzymes (AST, ALT), liver antioxidant enzymes (SOD, CAT, GPx) and lipid peroxidation marker (TBARS) were not changed in rats of 1 and 3 hours after ethanol treatment. After 20 days, GTE decreased the changes of liver marker enzymes (AST, ALT) activities and TBARS level by ethanol. This study shows that GTE beneficially modulates TNF-$\alpha$ and glutathione levels in liver of ethanol administered rats. The GTE supplementation could be beneficial to liver by decreasing early changes of biomarkers of liver damage caused by ethanol.

Circulatory and respiratory activities were observed in men exposed to the environment of engine room of a cruising Republic of Korea Navy ship and compared to the control values obtained in an ordinary laboratory room on land. The environment of an engine room of cruising navy ship was presumed to be a multiple stress acting on men. The environment of the engine room included high temperature $(35-42^{\circ}C)$, low relative humidity (20-38% saturation), vibration (about 7 cycles per second), rolling and pitching of ship and noises. Sixteen men were divided into two groups consisted of each 8 subjects. Subjects of sea duty group had experience of continuous on board duty averaging 3.5 years. Men of land duty group had no experience of on board activity. On land observations were made on one day prior to the boarding and leaving the port and four days after landing. In between observations in the engine room were made on the first, 5 th, 9 th, 12 th, and 14 th day of on board activity. The whole experimental period lasted for 20 days. Measurements on circulatory and respiratory parameters were at standing resting state (after 30 minutes standing in the case of on land study and 15 minutes in engine room study) and within one minute after cessation of on the spot running of which rhythm was 30/min. and lasted for 5 minutes. Oxygen consumption and pulmonary function test were done in the period of two minutes from the 3rd to 5th minutes of running. The following results were obtained. 1. Body temperature showed no change regardless of group difference or on land or on board measurements. 2. Pulse rate increased markedly after boarding the ship id both groups. Pulse rate increased from the first day on board at rest and after exercise as compared to the on land control value. This increase in pulse rate was more marked after exercise. Sea duty group showed less increase in pulse rate at rest than the land duty group. Standing and resting pulse rate of sea duty group on lam was 81 and increased to 87 at the 5th day on board and remained smaller than the land duty group throughout the period on board. Control standing and resting pulse rate of land duty group on land was 76 and reached 89 at the 9th day on board and thereafter decreased a little. Pulse rate of land duty group at rest on board remained greater than that of sea duty group throughout the period on board. 3. Systolic blood pressure of sea duty group increased after boarding the ship and remained higher than the control value on land. In the land duty group, however, systolic blood pressure decreased during the period on board the ship. Diastolic blood pressure decreased in both groups. 4. Resting breathing rate of land duty group increased and remained higher than the control value on land. In sea duty group, however, resting breathing rate showed a transient increase on the 1st day on board and decreased thereafter to the control value on land and kept the same level throughout the period of cruise. Absolute value of breathing rate in the sea duty group was greater than the land duty group both at rest and after exercise. 5. There was a lowering of breathing efficiency in both groups. Thus, increases in tidal volume and minute ventilation volume and decreases in maximum breathing capacity, vital capacity, capacity ratio and air velocity Index were observed after boarding the ship. An increase in ventilation equivalent was also observed in both groups. The lowering of breathing efficiency was more marked in the land duty group than the sea duty group. 6. Energy expediture increased in both groups during their stay on the ship and was more marked in the sea duty group. 7, Lactate concentration in venous blood at rest and after exercise increased after boarding the ship and no group difference was observed.

This study investigated the effect of mulberry fruit extract(MFE) on antioxidant and anti-inflammatory activities of middle aged women with rheumatoid factor (RF). Thirty two middle-aged subjects were divided into two groups which were normal middle-aged group (NMG) and abnormal middle-aged group whose serum RF level were > 10 u/mL (AMG). All groups had consumed MFE (100 mL/day) for 4 weeks. Anthropometric measurements, serum inflammatory factors, serum oxidative stress markers analyses were performed at baseline and then at 4 weeks following the study. There were no significant differences in anthropometric measurements, including BMI, WHR and body fat composition between two groups. But after 4 weeks MFE consumption, serum levels of C-reactive protein (CRP), ferric-reducing ability of plasma (FRAP), serum TNF-${\alpha}$, IL-2, IL-4 had significantly decreased (p<0.05) in AMG. These findings suggested that the MFE consumption as food may be protective against oxidation and inflammation like RA.

Purpose: The ginger rhizome (Zingiber officinale) is widely cultivated as a spice for its aromatic and pungent components. One of its constituents, 6-hydroxydopamine (6-OHDA) is usually thought to cross the cell membrane through dopamine uptake transporters, and induce inhibition of mitochondrial respiration and the generation of intracellular reactive oxygen species (ROS). This study examines the neuroprotective effect and acetylcholinesterase (AChE) inhibitory activity of fermented ginger extracts (FGEs) on 6-OHDA induced toxicity in SH-SY5Y human neuroblastoma cells. Methods: Ginger was fermented using 2 species of Bacillus subtilis, with or without enzyme pretreatment. Each sample was extracted with 70% ethanol. Neurotoxicity was assessed by applying the EZ-Cytox cell viability assay and by measuring lactic dehydrogenase (LDH) release. Morphological changes of apoptotic cell nuclei were observed by Hoechst staining. Cell growth and apoptosis of SH-SY5Y cells were determined by Western blotting and enzyme activity analysis of caspase-3, and AChE enzymatic activity was determined by the colorimetric assay. Results: In terms of cell viability and LDH release, exposure to FGE showed neuroprotective activities against 6-OHDA stimulated stress in SH-SY5Y cells. Furthermore, FGE reduced the 6-OHDA-induced apoptosis, as determined by Hoechst staining. The occurrence of apoptosis in 6-OHDA treated cells was confirmed by determining the caspase-3 activity. Exposure to 6-OHDA resulted in increased caspase-3 activity of SH-SY5Y cells, as compared to the unexposed group. However, pre-treatment with FGE inhibited the activity of caspase-3. The neuroprotective effects of FGE were also found to be caspase-dependent, based on reduction of caspase-3 activity. Exposure to FGE also inhibited the activity of AChE induced by 6-OHDA, in a dose-dependent manner. Conclusion: Taken together, our results show that FGE exhibits a neuroprotective effect in 6-OHDA treated SH-SY5Y cells, thereby making it a potential novel agent for the prevention or treatment of neurodegenerative disease.

This study was conducted to investigate the effects of the type and number of enrichments on growth performance, blood characteristics, footpad dermatitis (FPD) incidence, and litter moisture in broilers. A total of 1,140 1-day-old male Ross 308 broilers were assigned to a 3 × 2 factorial arrangement based on the type of enrichment (cabbage, alfalfa block, and angle sawdust) and the number of enrichments (one or two per 38 broilers). The growth performance, blood characteristics, FPD incidence, and litter moisture of the broilers were evaluated. Body weight and feed conversion rate were significantly improved (P<0.05) in the alfalfa block and sawdust group compared to the cabbage group, but there was no interaction effect between the type and number of enrichments. The heterophil/lymphocyte ratio, a stress index, was significantly decreased (P<0.05) in the alfalfa block and sawdust groups compared with the cabbage group. The incidence of FPD was significantly decreased in the order of cabbage (3.78), alfalfa block (3.06), and sawdust (1.43) groups at 5 weeks of age. Moreover, there was a significant decrease in the incidence of FPD (P<0.05) in the one-enrichment group compared with the two-enrichment group. Litter moisture at 5 weeks of age was significantly reduced in the sawdust group compared to the cabbage and alfalfa groups, but there was no significant difference in the interaction between the type and number of enrichments. It was concluded that sawdust enrichment positively influenced both growth performance and the animal welfare of broilers. In addition, it is expected that sawdust can be used to regulate litter moisture.

This study was conducted to investigate the effect of three different photoperiods on growth performance, blood properties, and stress indicators in broiler chicks between 1-7 days after hatching. Two hundred and fifty-two 1-day-old male broiler chicks (57.0±0.12 g) were divided into three treatments, with 4 replicates per treatment and 22 birds per replicate subjected to three different photoperiods of 24L, 22L/2D and 18L/6D. A light-emitting diode bulb served as the light source, with an illuminance of 30 lx. As an experimental diet, a commercial feed based on a corn-soybean meal, with 22% CP and 3,150 kcal/kg ME diet, and water were fed ad libitum. Body weight gain, feed conversion ratio, and liver weight ratio showed a statistically significant difference between the 18L/6D and 24L treatments (P<0.05), but with no significant difference between the 22L/2D treatment and either the 24L or 18L/6D treatment. The breast meat ratio was 5.59% in the 18L/6D treatment group, which was lower than that of other treatment groups (P<0.05). The triglyceride levels were highest (P<0.05) in the 18L/6D treatment among treatments, but alanine aminotransferase levels were significantly higher (P<0.05) in the 22L/2D treatment than in the 24L treatment. Levels of cytokines, i.e., Interleukin-6 and Tumor Necrosis Factor-α did not show a significant difference among the treatments, but corticosterone content was significantly higher (P<0.05) in the 24L treatment than in the 18L/6D treatment. In conclusion, 22 hours of lighting is appropriate between 1~7 days after hatching, considering growth performance and the overall health of broiler chicks.
