Objectives : This study aimed to evaluate the effect of Wongisaengmaek-san (extracted with water or 50% ethanol) on antioxidative activity and recovery of fatigue induced by weight-loaded forced swimming exercise. Methods : Antioxidant activity of Wongisaengmaek-san was evaluated in terms of total amount of polyphenol, 1.1-diphenyl-2-picrylhvdroxyl (DPPH) radical scavenging activity and xanthine oxidase inhibition. The anti-fatigue effect of Wongisaengmaek-san was investigated using an acute weight-loaded forced swimming test by monitoring swimming test times and blood biochemical parameters creatinine. BUN, lactic acid dehydrogenase (LDH), free fatty acid (FFA) and lactic acid (LA). Results : 1. 50% EE (ethanol extract) had 2.3 times higher amount of total polyphenol compared to water extract. 2. It was identified that 50% ethanol extract showed enhancement of xanthine oxidase inhibition and DPPH scavenging effect in vitro. 3. According to anti-fatigue effect in the scale of 5% weight loaded mouse swimming test, both water and 50% ethanol extract showed significant improvement of swimming time elongation respectively, and 50% ethanol extract induced a more positive result. 4. After swimming for 1% weight-loaded mouse. water extract and 50% ethanol showed significant anti-fatigue effect with manifestation of blood sampling among both of the intervention: 50% ethanol extract showed a greater result. Conclusions : 50% ethanol extract of Wongisaengmaek-san has more effective antioxidant activity and anti-fatigue than water extract.

Both ethanol and water extracts of unossified velvet antler were found to exhibit a significant immuno-stimulating activity as measured by carbon clearance test in mice, a remarkable anti-fatigue effect in weight-loaded forced swimming performance in mice, a significant anti-stress effect on immobilization in rats. The antler extracts also showed a weak but significant anti-thrombotic activity. These findings are indicative of adaptogenic properties of antlers and their normalizing effects during stressful condition.

$Nokyangbotang^{TM}$ (NYBT) is a kind of powerful food for health and have been drunk at a oral dose of 80 ml (99.5 mg) three times per day: It has not been well studied about the anti-fatigue and hepatoprotective activity. In this experiments, we evaluated pathophysiologically the effect of NYBT on swimming time in mouse and hepatoprotective activity in rats intoxicated with carbon-tetrachloride. NYBT was nontoxic in orally acute toxicity test ($LD_{50}$, 320 ml/60 kg): a nontoxic food in more four times of one-shoot dosage (80 ml) to human. Weight-loaded forced swimming test was carried out to measure the swimming time of mice with a 4% load of body weight in plastic cylinder (diameter $10{\;}cm{\;}{\times}{\;}height{\;}20{\;}cm$) on water bath at $25^{\circ}C$, and the anti-fatigue activity represented the ratio of swimming time of experimental group to that of control group. NYBT had dose-dependent anti-fatigue activity Mice administered NYBT at a dose of 320 ml/60 kg once daily for 5 days could swim about two times more than control. Hepatoprotective activities of NYBT were examined by the determination of malonedialdehyde (MDA) and pathological survey in liver and liver function test of rat intoxicated with $CCl_4$ at i.m. dose of 2 ml/kg once daily for 7days. NYBT decreased dose-dependently thiobarbituric acid reactive substance: Oral administration of NYBT at a dose of 20 ml/60 kg was $38.51{\;}{\pm}{\;}3.02$ nmol MDA/g of tissue, that of 80 ml/60 kg was $33.76{\;}{\pm}{\;} 1.84$ nmol MDA/g of tissue, and that of 320 ml/60 kg was $32.87{\;}{\pm}{\;}1.90$ nmol MDA/g of tissue as compared with control group ($43.61{\;}{\pm}{\;}2.85$ nmol MDA/g of tissue). All rats administered NYBT at a dose of 320 ml/60 kg were survival as compared with 40% survival of control animals, and GPT activity of rats administered NYBT at a dose of 80 ml/60 kg was decreased as compared with control. In histopathological survey, NYBT improved slightly the fatty changes of hepatocytes around centrilobular area. These results suggest that NYBT has anti-fatigue and hepatoprotective activity in rats and mice.

Processing of traditional herbal medicine is one of the pharmaceutical technique in oriental medicine. Most frequently used processing method in oriental medicine are roasting and steaming. In this studies, to elucidate the pharmacological transformation of traditional herbal medicine by means of processing them, Ginseng Radix (root of Panax ginseng, Araliaceae) was used as a sample. Processed ginseng radix (SGR, Sun Ginseng) was prepared by steaming of roots of white ginseng (GR) for 3 hours at $120^{\circ}C$. The biological activities of methanol extract of GR and SGR were investigated. According to DPPH radical scavenging effects, and inhibitory effects of xanthine oxidase and AAPH induced hemolysis, PGR exhibited more effective than those of GR in vitro. And, the antifatigue effect of GR and SGR were investigated using a weight-loading forced swimming test by monitoring swimming times and prolonged intensity exercise model rats by measuring blood biochemical parameters. GR and SGR were significantly prolonged swimming times in 8% body weight ratio loaded mice. Also, they had the inhibitory effects on the decrease of blood glucose levels, the elevation of serum creatinine, lactic acid and free fatty acid, and lactic dehydrogenase activities in forces swimming rats with 1% of the body weight attached to the neck for 3 hours. SGR was more excellent than GR on these effect. Also, these effects were transformed to the n-butanol fraction of methanol extract of SGR. From these results, it can be considered that SGR has antifatigue effect.

Acharan sulfate (AS) is a glycosaminoglycan (GAG) prepared from the giant African snail, Achatina fulica. In this study, some biological activities of AS were evaluated on the basis of structural similarities to heparin/heparan sulfate and the biological functions of GAGs. We demonstrated that it exhibited strong immunostimulating activities as measured by carbon clearance test in mice and in vivo phagocytosis. It also exhibited a significant hypoglycemic activity in epinephrine (EP)-induced hyperglycemia as well as antifatigue effects by weight-loaded forced swimming test. And it showed hypolipidemic activities in cholesterol-rich mixture induced hyperlipidemia in rats. The above results indicate that AS has diverse biological activities and suggest therapeutically important target molecules.

Objectives : Jakyakgamcho-tang has been used as analgesic and spasmolytic for muscle pain. It has reported to anti-diabetes, anti-inflammation, and neuro-protective effects. A clinical study of muscle fatigue and pain improvement effect of Jakyakgamcho-tang has been reported with increasing frequency of clinical use. However, the anti-fatigue effect of Jakyakgamcho-tang in animal model has not been studied. In this study, we compared anti-physical fatigue effects of water and 30% ethanol extract of Jakyakgamcho-tang. Methods : The amounts of components contained in water and 30% ethanol extract of Jakyakgamcho-tang were compared by ultra-performance liquid chromatography. Anti-physical fatigue effects were evaluated using weight-loaded forced swimming test. We also investigated the effects of Jakyakgamcho-tang on the change of fatigue parameters by blood biochemical analysis. Results : The relative amount of components of Jakyakgamcho-tang were about 19-53% higher in the 30% ethanol extract than in the water extract. In the swimming test, 30% ethanol extract showed a significantly greater anti-fatigue effects than conventional water extract of Jakyakgamcho-tang. The 30% ethanol extract of Jakyakgamcho-tang improved the exhausted swimming time (54%), and serum lactate dehydrogenase (48%) and lactic acid (60%) levels compared with water extract of Jakyakgamcho-tang. Conclusions : These results showed that differences in the amounts of components by different extraction were associated with differences of anti-fatigue effect of Jakyakgamcho-tang. Thus, the 30% ethanol extraction method could be applied to dose-reducing formulations of traditional herbal medicines.

Water and methanol extracts of cricket were examined for their liver protective effects against $CCl_4-intoxication$ in ICR-mice. Serum transaminases (S-GOT and S-GPT), lactate dehydrogense (LDH) and glutathione-S-transferase (GST) activities and TBARS (Thiobarbiturate-reactive substances) content were measured for evaluation of liver protective effects. The activities of GOT, GPT, LDH and hepatic content of lipid peroxide after $CCl_4-treatment$ were higher than normal control but those levels decreased th 74, 50, 101 and 40%, respectively, by the treatment of cricket methanol extract. The anti-fatigue effects of water and methanol extracts investigated by an acute weight-loaded forced swimming test showed significantly prolonged swimming time in the mice administered cricket extracts. These results suggest us that water/alcohol extract of G. bimaculatus may be used as a liver protective food.
