The effects of Tabebuia avellanedae (Taheebo) on exercise endurance capacity were investigated using mice in an adjustable-current water pool. Compared to the control group, a 1.8~2.0 fold increase in swimming time was observed in mice administered hot water extract (TAW) and 80% ethanol extract (TAE) of inner bark from T. avellanedae. Blood lactate level, an important fatigue relevance factor, was significantly lower in the TAW and TAE groups than in the control group. The total phenolic contents of TAW and TAE were $93.3{\pm}1.6$ and $115.7{\pm}1.5mgGAE/g$, respectively. The levels of flavonoids in the extracts were $77.3{\pm}1.3$ and $95.9{\pm}1.7mgCE/g$, respectively. Higher antioxidant activities of TAE were observed in each assay at the same concentration as compared to TAW. Correlation between antioxidant activities of TAE with total polyphenol contents was observed. These results suggest that extracts of Taheebo increase exercise endurance capacity by elevating antioxidative potentials.

Objectives : Pyeongwi-san is widely used in Korean medicine for acute indigestion or gastrodynia. As a therapeutic agent for digestive diseases of modern people, in order to confirm the mechanism of Pyeongwi-san on digestive tract disease and the difference of therapeutic efficacy between its formulation, a comparative efficacy test was conducted on digestive tract disease animal model. Methods : For LPS enteritis animal model, male SD rats were intraorally treated with different formulation types of Pyeongwi-san, and then intraperitoneally administered LPS one hour later to induce enteritis. After 5 hours, blood was collected and TNFα, IL-1β, IL-6 and PGE2 were confirmed by ELISA. For acute gastritis animal model, male SD rats were intraorally treated with different formulation types of Pyeongwi-san according to the prescribed concentration, and then intraorally administered 60% ethanol and 150 mM HCl one hour later to induce acute gastritis. After 5 hours, blood was collected and TNFα,IL-6 were confirmed by ELISA. Results : In the LPS-administered enteritis animal model, Pyeongwi-san decreased TNFα, IL-1β, PGE2 and especially IL-6. Pyeongwi-san also decreased IL-6 in acute gastritis animal model. In addition, there was no significant difference in efficacy between the two formulations when compared with inflammatory markers. Conclusions : The efficacy of Pyeongwi-san was confirmed in the inflammatory markers related to digestive inflammatory diseases, and the efficay between two formulations of Pyeongwi-san was relatively similar. Further studies are needed to investigate the new applicability of Pyeongwi-san on different inflammatory diseases that have similar inflammation markers identified in this experiment.

Ginsenosides are major constituents of ginseng and are known to be responsible for its pharmacological properties. This study aimed to investigate the detoxification effect of a mixture containing black red ginseng powder, red ginseng extract, Puerariae radix extract, and Hovenia dulcis extract, on SD (Sprague Dawley) rats treated with 30% ethanol. Thirty minutes before treatment, the animals were orally administered different concentrations of the mixture or water. Results revealed that the concentration of ethanol in blood serum was significantly decreased in the black red ginseng mixture treated group in a dose-dependent manner, as compared with that of the control group. The blood level of acetaldehyde increased until 1 hr after alcohol administration, but the levels rapidly decreased later. Furthermore, ADH and ALDH activities in the hepatic tissue were also increased in the black red ginseng mixture administered group, than in the control group. These results indicate that the black red ginseng mixture has the ability of decomposing alcohol by increasing the ADH and ALDH activities responsible for alcohol metabolism.

Objectives : Samhwangsashim-tang(SHSST), a mixture of Rhei radix et rhizoma, Scutellariae radix, and Coptidis rhizoma, has been regarded as being able to treat bleeding, gastric discomfort, dry mouth, insomnia and purpura due to Blood Heat. Currently, this herbal formula is applied to gastritis, gastric ulcer, hypertension, atherosclerosis or other types of vascular inflammatory disorders. Methods : We extracted this herbal mixture with 30% ethanol and examined for its effects on systemic inflammatory responses and in vitro macrophage activity. Mice were orally given to SHSST for 7 days and then lipopolysaccharide(LPS) was intraperitoneally injected. Tumor necrosis factor-${\alpha}$(TNF-${\alpha}$) levels in serum were measured 1 h after LPS challenge. Peritoneal macrophages were isolated from thioglycollate-injected mice and used for in vitro cellular activity. Cell death was measured using the MTT method and annexin V/propidium iodide staining. LPS-stimulated signaling molecules necessary for TNF-${\alpha}$ expression were determined by Western blotting. Results : Oral administration of SHSST for 7 days resulted in a significant reduction in LPS-stimulated TNF-${\alpha}$ release into serum. In vitro treatment of SHSST was cytotoxic in a concentration-dependent manner. However, SHSST caused a concentration-dependent reduction in necrosis and increase in apoptosis in mouse peritoneal macrophages. SHSST inhibited the activation of NF-${\kappa}B$, p38 and JNK signaling molecules in response to LPS. Conclusion : Taken together, our results demonstrated that SHSST was effective in lowering LPS-stimulated TNF-${\alpha}$ serum levels, possibly through its modulation of NF-${\kappa}B$, p38 and JNK in macrophages.

Two experiments were conducted to determine the nutrient composition, in vitro ruminal ammonia concentrations and pH of wet distillers grains (WDG, produced from tapioca 70% and rice 30%) and to evaluate dietary effects of fermented total mixed ration (TMR) using WDG on the performance, blood metabolites and carcass characteristics of Hanwoo steers from mid fattening to slaughter. In Exp. I, average dry matter (DM), crude protein, ether extract, crude fiber, ash, neutral detergent fiber, acid detergent fiber, and nitrogen free extract of seven WDG samples from an ethanol plant with different sampling dates were 19.9%, 24.8%, 3.8%, 21.8%, 8.87%, 60.3%, 34.5%, and 40.7% (DM basis), respectively. For in vitro ammonia concentrations and pH, each sample was assigned to 7 incubation times (0, 4, 8, 12, 24, 48, and 72 h). Linear increase was observed between 12 and 48 h for ammonia concentrations, but final ammonia concentrations (72 h) were not significantly different among WDG samples and fermentation patterns of WDG samples showed similar tendency. In vitro pH varied among treatments from 0 to 24 h, but were not different statistically after 48 h. In Exp. II, 45 Hanwoo steers of 23 months ($641{\pm}123kg$) from mid fattening period to slaughter (248 days) were randomly divided into three groups of 15 pens each (five repetitions/each treatment) and assigned to one of three dietary treatments; i) Control (TMR), ii) WDG 15 (TMR containing 15% of WDG, as fed basis) and iii) WDG 28 (TMR containing 28% of WDG, as fed basis). The body weight (BW), ADG, and feed conversion ratio (FCR) of control and WDG 15 and 28 during 248 days were 760.8, 740.1, and 765.5 kg, and 0.50, 0.50, and 0.52 kg/d, and 18.6, 17.6, and 17.1, respectively. The dry matter intake (DMI) (kg/d) of control (9.11) was higher (p<0.05) than WDG treatments (WDG 15%, 8.57; 28%, 8.70). Nevertheless, DMI did not affect BW, ADG, and FCR of Hanwoo finishing steers. Blood metabolites were in normal ranges and were not different among treatments except the albumin concentration. In carcass characteristics, WDG 15 (30%) showed higher frequency of A-carcass yield grade than WDG 28 (15%) and control (7%), and WDG 28 (61%) showed higher frequency of $1^{{+}{+}}$ and $1^+$-carcass quality grade than WDG 15 (40%) and control (60%). In conclusion, using WDG up to 28% in TMR did not show any negative effect on the performance and blood metabolites, and improved carcass quality of Hanwoo steers. Therefore, WDG can be a useful feed ingredient for Hanwoo steers in mid-fattening period to slaughter.

To examine the effects of alcohol consumption on body fluid restoration and fat mobilization following exercise induced dehydration, nine healthy collegiate men ($24{\pm}2yrs,\;177{\pm}5cm,\;72{\pm}8kg,\;10.5{\pm}2.3%$ body fat) underwent three experiments. In each experiment, subjects ran on a treadmill to reduce individual body mass to $2.2{\pm}0.1%$ and consumed one of three beverages containing 0, 4, or 8% alcohol over 60 min followed by 4 hr of resting recovery. They consumed approximately 150% of weight loss $(2053{\pm}204,\;2091{\pm}149,\;and\;1943{\pm}295mL)$ and content of alcohol was $9.9{\pm}1.0(0%),\;71.9{\pm}5.1(4%)$, and $132.2{\pm}20.1g$ (8% trial). Body weight, urine volume and samples, blood samples, and thirst sensation were measured five times; at baseline, immediately after exercise, and 0, 1st, and 4th hr of recovery. Blood alcohol concentration after ingestion was $0.0{\pm}0.0(0%),\;0.1{\pm}0.02(4%)$, and $0.2{\pm}0.03%$ (8% trial). No differences in blood sodium and potassium concentrations, and urine specific gravity were noticed over time periods and trials. Thirst sensation tended to be elevated in all trials immediately after exercises and urine output was elevated during the recovery. The magnitude of changes in these variables was proportional to the alcohol concentrations, but not statistically significant. While serum osmolality was not different among trials and time periods in 0 and 4% trials, it was higher during recovery than the baseline in the 8% trial (P<0.01). Triglycerides did not change throughout the time period and among trials. Free fatty acids were elevated after exercise in all trials and 4th hr of recovery in 0% (P<0.05). Subjects' net body fluid balance at 4th hr of recovery was negatively maintained and proportional to alcohol concentrations. Only 8% trials showed a significant reduction at 1st and 4th hr of recovery compared to 0 hr. The results suggested that diuretic effect of alcohol after moderate level of dehydration appeared dose dependent, but beverage containing alcohol up to 4% did not induce impaired rehydration than alcohol free drinks. Alcohol effects on fat mobilization during recovery appeared to be minimal and the mechanism is unclear.

This study aimed to verify the antidiabetic effects of the unripe black raspberry extract (UBRE) in obese diabetic mice. For the experiment, animal model mice were divided into six groups: normal control, diabetic control, three experimental groups (treated with 75, 150, and 300 mg/kg single dose of UBRE), and a positive control (200 mg/kg metformin). The groups treated with 300 mg/kg UBRE and metformin had significantly reduced blood glucose and triglyceride levels in the diabetic mice compared to those in the vehicle control group. In addition, histopathological evaluation showed that UBRE increased the Langerhans area, cell number, and insulin concentration in the pancreatic islets of db/db mice. Therefore, UBRE exerts significant antidiabetic effects by decreasing the blood glucose and lipid levels, suggesting that it can be consumed as a functional diet for diabetic patients.
