This study was to investigate the effect of long-term high intensity endurance training on the activation of antioxidation enzyme activity, lipid peroxidation and lipoprotein metabolism. 15 subjects were divided into, endurance exercise + antioxidation Vitamin supplement(n=5), endurance exercise(n=5), and the control(n=5) groups. The endurance exercise groups(endurance exercise + antioxidation Vitamin supplement and endurance exercise) had 12 week of endurance exercise program. The antioxidation Vitamin supplement group was taken a Vitamin C tablet with 1000mg/day and Vitamin E tablet with 671.14mg/day right after lunch. The results obtained from this study were as follows; 1. Looking at the changes of SOD, Endurance exercise+antioxidation Vitamin supplement group and endurance exercise groups showed the significantly greater decrease in the activation of SOD after 12 weeks of all-out exercise. 2. Looking at the changes of CAT, Endurance exercise+antioxidation Vitamin supplement group revealed subjects tended to increase CAT after all-out exercise although statistically non-significant. Endurance exercise+antioxidation Vitamin supplement group showed the significantly greater increase in the activation of CAT after 12 weeks treatment for all-out exercise. 3. Looking at the changes of GPX, Endurance exercise+antioxidation Vitamin supplement group revealed subjects tended to increase GPX for the rest and after all-out exercise although statistically non-significant. Endurance exercise+antioxidation Vitamin supplement group showed the significantly greater increase in the activation of GPX after 12 weeks treatment for all-out exercise. 4. The MDA change showed the significant decrease after 6 weeks, after 12 weeks for the all-out exercise of Endurance exercise + antioxidation Vitamin supplement group. 5. There was non-significant change in lipoprotein metabolism for the rest and after all-out exercise.

Objectives : This study was performed to investigate the effects of Cordyceps Sinensis (CS) and Cordyceps Militaris (CM) on anti oxidation in the livers of ${CCl_4}-treated$ rats. Methods : Hepatotoxicity in rats was induced by carbon tetracWoride. $CCl_4-induced$ rats were administered with the extract of CS and CM. Results : In vitro, CS and CM didn't affect levels of lipid peroxide and the activities and type conversion ratio of xanthine oxidase. However, hydroxyl radicals and DPPHL radicals were decreased. In vivo, in the ${CCl_4}-treated$ rats, lipid peroxide, the activities and type conversion ratio of xanthine oxidase and superoxide radicals were increased but superoxide dismutase was decreased. After CS and CM were administered to ${CCl_4}-treated$ rats, levels of lipid peroxide, the activities and type conversion ratio of xanthine oxidase and superoxide radicals were decreased but superoxide dismutase was increased. Conclusions : These results suggest that CS and CM decrease the activities of free-radical-generating enzymes which form lipid peroxide and increase the activities of oxygen free radical scavenging enzymes.

Objectives : Cordyceps Sinensis (CS) was tested for the effects of antioxidant enzymes and lipid peroxidation in the liver. Methods : We measured the changes in body weight, enzyme activity, lipid peroxide and the death rate in the hydrocortisone acetate-treated rats. Results : In vitro, CS didn't effect levels of lipid peroxide. the activities, and the ratio of type conversion of xanthine oxidase. In the hydrocortisone acetate-treated rats, lipid peroxide, the activities, the ratio of type conversion of xanthine oxidase, and the death rate all increased. But, glutathione peroxidase and superoxide dismutase decreased. In vitro, after CS was administered to hydrocortisone acetatetreated rats, the levels of lipid peroxide in the liver, and the death rate decreased. However, the activities, and the ratio of type conversion of xanthine oxidase decreased. The body weight, glutathione peroxidase, and superoxide dismutase in+creased. The effects of Sinensis Cordyceps Broth did better than the effects of Sinensis Cordyceps Mycelia. Conclusions : These results suggest that CS decrease the activities of free radical generating enzymes which form lipid peroxide and increase the activities of oxygen free radical scavenging enzymes.

Objective: This study was investigated the effects of dietary supplementation of Antrodia cinnamomea fermented product on modulation of antioxidation, anti-inflammation, and lipid metabolism in broilers. Methods: Functional compounds and in vitro antioxidant capacity were detected in wheat bran (WB) solid-state fermented by Antrodia cinnamomea for 16 days (FAC). In animal experiment, 400 d-old broiler chickens were allotted into 5 groups fed control diet, and control diet replaced with 5% WB, 10% WB, 5% FAC, and 10% FAC respectively. Growth performance, intestinal microflora, serum antioxidant enzymes and fatty acid profiles in pectoral superficial muscle were measured. Results: Pretreatment with hot water extracted fermented product significantly reduced chicken peripheral blood mononuclear cells death induced by lipopolysaccharide and 2,2'-Azobis(2-amidinopropane) dihydrochloride. Birds received 5% and 10% FAC had higher weight gain than WB groups. Cecal coliform and lactic acid bacteria were diminished and increased respectively while diet replaced with FAC. For FAC supplemented groups, superoxide dismutase (SOD) activity increased at 35 days only, with catalase elevated at 21 and 35 day. Regarding serum lipid parameters, 10% FAC replacement significantly reduced triglyceride and low-density lipoprotein level in chickens. For fatty acid composition in pectoral superficial muscle of 35-d-old chickens, 5% and 10% FAC inclusion had birds with significantly lower saturated fatty acids as compared with 10% WB group. Birds on the 5% FAC diet had a higher degree of unsaturation, followed by 10% FAC, control, 5% WB, and 10% WB. Conclusion: In conclusion, desirable intestinal microflora in chickens obtaining FAC may be attributed to the functional metabolites detected in final fermented product. Moreover, antioxidant effects observed in FAC were plausibly exerted in terms of improved antioxidant enzymes activities, increased unsaturated degree of fatty acids in chicken muscle and better weight gain in FAC inclusion groups, indicating that FAC possesses promising favorable mechanisms worthy to be developed.

The production of matrix metalloproteinases (MMPs) by the UV irradiated skin fibroblast and the degradation of extracellular matrix (ECM) by these enzymes is known as one of the main reasons of photoaging. In this paper, to investigate the relationship between aging and Selaginella tamariscina extract (STE), we investigated the effects of antioxidant and expression of UVA-induced MMP-1 in human dermal fibroblasts. STE was found to show scavenging activities of radicals and reactive oxygen species (ROS) with the $IC_{50}$/ values of 65.1 $\mu\textrm{g}$/$m\ell$ against 1,1-diphenyl-2-picrylhydrazyl(DPPH) radical and 40.9 $\mu\textrm{g}$/$m\ell$ against superoxide radicals in the xanthine/xanthine oxidase system, respectively. UVA induced MMP expression was reduced 75.5% by treatment with STE, and MMP-1 mRNA expression was reduced in a dose-dependent manner. Therefore STE was able to significantly inhibition of MMP expression in protein and mRNA level. All these results suggested that STE may act as an anti-aging agent by antioxidation and reducing UVA-induced MMP-1 production.

Objectives : In this study, we investigated the immunomodulatory and antioxidant effect of MOK, a pharmacopuncture medicine, in concanavalin A (Con A)-stimulated mouse splenocytes. Methods : Primary splenocytes were isolated from ICR mice. The splenocytes were treated with MOK extract (1.25, 2.5, 5, 10, and 20 mg/mL) for 30 min and then stimulated with Con A (200 ng/mL) for the indicated times. Cell viability of the splenocytes was measured using an MTT assay. The mRNA expression of Th1/Th2 cytokines ($IFN-{\gamma}$, IL-4, IL-10, and Foxp3) and antioxidant enzymes (HO-1 and MnSOD) was measured by RT-PCR. Results : Addition of MOK extract at 2.5, 5, and 10 mg/mL in Con A-stimulated splenocytes significantly decreased the production of $IFN-{\gamma}$ and significantly increased the expression of IL-4, IL-10, and Foxp3 mRNA. MOK extract also increased the mRNA expression of HO-1 and MnSOD in splenocytes. Conclusion : MOK extract modulated the Th1/Th2 immune response via the regulation of cytokine levels in splenocytes and exerted an antioxidant effect via the upregulation of antioxidant proteins.

To understand the adaptability of alfalfa (Medicago sativa L.) to chilling stress, we analyzed the antioxidative mechanism during seed germination. The germination rates of six alfalfa cultivars were studied comparatively at $10^{\circ}C$. Xinmu No. 1 and Northstar were selected as chilling stress-tolerant and stress-sensitive cultivars for further characterization. After chilling treatment, Xinmu No. 1 showed higher seedling growth than Northstar. Xinmu No. 1 exhibited low levels of hydrogen peroxide and lipid peroxidation compared with Northstar. In addition, shoots in Xinmu No. 1 treated with chilling showed higher activities of the superoxide dismutase, ascorbate peroxidase (APX), and catalase than those of Northstar, whereas Xinmu No. 1 showed higher APX activity in roots that Northstar. These results indicated that high antioxidation activity in Xinmu No. 1 under chilling stress is well associated with tolerance to chilling condition during germination.

This study was performed to examine the feeding effects of $Angelica$ $keiskei$ $Koidz$ (AK) and its processed products on serum, liver, and body fat content and the expression of antioxidant genes in rats fed a high fat diet. AK and its processed products were added at 3-5% to a high fat diet and fed to adult rats for 6 weeks. In experiment 1 (EXP 1), the rats were fed with one of six diets including a control diet (normal fat), high fat diet (HF), and HF + AK additives groups (four groups). In experiment 2 (EXP 2), the rats were separated into three groups of HF, HF + AK whole leaves, and HF + fermented juice (FS) + squeeze (SA). Body weight was not different among the groups in either experiment. The liver weight was lower in the FS and SA groups compared to that in the other groups (P<0.05). Serum luteolin was higher in the AK and processed products groups compared to that in the HF group (P<0.05). Gene expression of the antioxidative enzymes catalase and glutathione-s-reductase in the liver was higher in the AK processed products group than that in the other groups (P<0.05). The results suggest that the intake of AK and its processed products increased the expression of antioxidant enzymes in animals fed a high fat diet, reduced hepatic cholesterol content, and increased the effective absorption of luteolin.

Cervus elaphus for herb-acupuncture solution(CEHAS) was tested for the effects of free radical generating enzyme and lipid peroxidation in rat's liver. In vitro, levels of lipid peroxide in tissues of liver were proportionally decreased to concentration of CEHAS. They were much more decreased. when lipid peroxidation was induced with ferrous iron $(Fe^{-2})$. Also, enzyme activities of xanthine oxidase were decreased. The ratio of type conversion of xanthine oxidase was lowered, too. But, here was not special changes on enzyme activities of aldehyde oxidase. These results suggest that CEHAS decrease the activities of free radical generating enzymes such as xanthine oxidase which form lipid peroxide.
