The purpose of this study was to investigate the antioxidant effects of non-fermented (CAC) and Monascus pilosus-fermented Columbia arabica coffee (FCAC), as well as Luwak coffee (LC) beans. The results indicated that total polyphenols content (mg/g of dry basis) was highest in CAC (70.69), followed by LC (62.07), and FCAC (41.38). However, the ratio of total flavonoids/polyphenols in FCAC was the highest. In terms of electron donating ability (%, coffee mg/mL), CAC was significantly higher than LC and FCAC. Regardless of fermentation, ferric reducing antioxidant powers were similar in CAC and FCAC and lowest in LC. LC also had the highest inhibitory activity against xanthine oxidase (XO). However FAAC had the highest inhibitory activity against aldehyde oxidase (AO), with nearly three times the levels found in CAC and LC. According to the above results, FCAC had a higher ratio of flavonoids/polyphenols and iron chelating activity than CAC. FCAC also had the highest AO inhibitory activity among the three experimental coffee beans. The results suggest that further studies are required to evaluate the bioactive components of various coffee beans so as to determine the potential benefits that coffee may have on preventing oxidative stress-related conditions.

Cervus elaphus (CE), being known to reinforce Kidney, have tested to study the effects concerning damages of renal tissue induced by oxygen free radicals. I had observed the effects of CE extract on damages of rat's kidney following ischemia and reflow. Before ischemia was caused, CE extract was applied $0.2m{\ell}$ per 250g through femoral vein in ischemia and reflow group and normal sailine was applied in normal group, Ischemia was caused by renal artery's clamp for 60 min and reflowed by clamp remove after 30 min. It was increased on the content of lipid peroxidation, activies and type conversion ratio of xanthine oxidase following ischemia and reflow. by clamp remove after 30 min. It was increased on the content of lipid peroxidation, activies and type conversion ratio of xanthine oxidase following ischemia and reflow. However, they were decreased when CE extract was pre-applied. Glutathione level was decreased in ischemia and reflow group, and increased in CE extract's pre-applied group. However, it could not seen special changes on aldehyde oxidase activities, either. In conclusion, CE extract recovers the damage of kidney due to ischemia and reflow by decreasing the lipid peroxidation.

To investigate an effect of Gam-Roa tea on the free radical or alcohol detoxicating enzyme activities, the rats got a drink at the Gam-Roa tea instead of water for 3 months, and then the animals were sacrificed and obtained the following findings. The animals receiving Gam-Roa tea showed a decreasing tendency of hepatic xanthine oxithine oxidase activity and significantly incresed content of cytochrome P-450 compared with the control. Furthermore, hepatic superoxide dismutase and glutathione S-transferase activities were also more increased in rats received Gam-Roa tea than in the control group, those receiving water. On the other hand, alcohol or aldehyde dehydrogenase activities were more increased in rats receiving Gam-Roa tea than the control. In conclusion, it is likely that the liver of rats receiving Gam-Roa tea may have the oxygen free radical or alcohol detoxication potential.

To elucidate the effect of acute ethanol pretreatment on some toluene metabolizing enzyme activities, rats were divided into 4groups: control, alcohol-treated, toluene-treated, rat's and toluene-treated rats pretreated with ethanol. The alcohol or toluene-treated rats showed the significantly increased activities of hepatic aniline hydroxylase(AH) and aminopyrine demethylase(AD) compared to the control group. And the toluene-treated rats pretreated with ethanol showed somewhat decreased tendency of these enzyme activities compared to only toluene-treated rats. Liver benzylalcohol or aldehyde dehydrogenase activities were higher in alcohol or toluene-treated rats than those of the control group. The toluene-treated rats showed the decreased tendency of benzylalcohol dehydrogenase activities by the pretreatment of alcohol. Furthermore, toluene treated-rats showed the markedly decreased activity of benzaldehyde dehydrogenase by the ethanol pretreat-ment. On the other hand, hepatic xanthine oxidase activity in toluene-treated animals pretreated with ethanol was significantly higher than those of the toluene alone-treated rats. These results indicate that the combination of ethanol with toluene treatment for a short period of time possibly results in decreased activity of some toluene metabolizing enzymes in rats.

This study investigated the effect of Puerariae Flos (PF; flower of Puerariae plant) and Puerariae Radix (PR; root of Puerariae plant) water extracts on the activities on the activities of ethanol-metabolizing enzymes and free radical generating/scavenging enzymes of brain in ethanol-treated rats. Five groups of male Sprague-Dawley rats were orally administered ethanol (25%, v/v) 5 g/kg body weight/day, and sacrificed 5 weeks post treatment. PF and PR water extracts were supplemented in a diet based on 1.2g (I) or 2.4 g (II) raw PF or PR/kg body weight/day. Alcohol dehydrogenase activity of brain was significantly lowered in PF of PR groups, whereas aldehyde dehydrogenase activity was significantly higher in PR groups than those of control and PF groups. Cytochrome P-450 content, aminopyrine D-methylase and aniline hydroxylase activities were decreased in both PF and PR groups compared to control group. Aldehyde oxidase and xanthine oxidase activities tended to decrease by Puerariae plant extract supplemented goups and degree of decrease predominated in PRI. Superoxide dismutase and glutathione S-transferase activities were increased in PF or PR groups, whereas glutathione peroxidase and catalase activities were significantly decrased by Puerariae plant extracts supplement. These results indicated that supplementation of PF or PR lowers free radical generating enzymes activities. It was suggested that the activities of ethanol metabolizing emzymes and antioxidant enzymes in brain can be enhanced by PF or PR supplement in ethanol-treated rats.

In this study, we designed a method to manufacture elevated fermented green tea by using Monascus pilosus, which is known as a functional microbe, and observe its antioxidant abilities and quality characteristics. The water-soluble substance (WSS) content of the fermented tea by M. pilosus (FTM) was lower than that of the non-fermented tea (NFT), although the alcohol-insoluble substance (AIS) content of the FTM was higher than that of NTM. On the other hand, the fractionated distilled water-soluble polysaccharide (DWSP), CDTA-soluble polysaccharides (CDSP), sodium carbonate-soluble polysaccharide (SCSP) and KOH soluble hemicellulose (HC) obtained from the AIS of the FTM was markedly higher than that of NFT. In the antioxidant parameters, the electron donating ability of all fractions, except HC, extracted from FTM was higher than that of NFT, and iron chelating ability of all fractions, except CDSP, extracted from FTM was higher than that of NFT. Whereas the DWSP and SCSP obtained from the FTM were higher than that of NFT, the activity of the HC fraction from both NFT and the FTM could not be detected. In addition, the xanthin oxidase (XO) inhibitory activities of the DWSP, CDSP and the SCSP obtained from the NFT were significantly higher than that of FTM, the aldehyde oxidase (AO) inhibitory activities of the DWSP and SCSP extracted from the FTM were markedly higher than that of the NFT. Meanwhile, the acceptance of NFT and FTM had no significant difference, while the quality of aroma, taste and mouthfeel of the FTM was higher than that of NFT. These results suggest that the post-fermented tea by Monascus microorganisms may be responsible for functional components as well as contribute to the improvement of the tea quality.

SANGNYANGHYOLTANG(SYT) is one of the most important prescription that has been used in oriental medicine for diabetes mellitus. The sudy was done in order to elucidate the anti-diabetic effect of SYT. After pretreatment of SYT(1,000mg／kg) for 6 weeks, the effect of of SYT was prevented on serum liver function test and hepatic lipid peroxide content in rats i.v. injected with streptozotocin(STZ, 50mg／kg, tail vein) 5 weeks after pretreatment of SYT. The hepatic microsomal cytochrome P-450 and aniline hydroxylase were significantly decreased, and aminopyrine N-demethylase activity was significantly increased in SYT-STZ group as compared with control group. Changes in aldehyde oxidase, xanthine oxidase, superoxide dismutase, catalase, epoxide hydrolase, UDP-glucuronyltransferase and sulfotransferase activities were not significantly different in any of the group. The cytosolic glutathione S-transferase activity was significantly decreased in SYT-STZ group as compared with control group. The selenium-independent glutathione peroxidase was significantly increased in SYT-STZ group as compared with control group, but there was no significant difference in selenium-dependent glutathione peroxidase in any of the groups. The hepatic glutathione concentration was significantly increased in SYT-STZ group as compared with control group, and ${\gamma}-glutamylcystein$ synthetase and glutathione reductase activities were not significantly different in any of the groups. The hepatic lipid peroxide content, serum aminotransferase and sorbitol dehydrogenase activities were slightly decreased in significantly in SYT-STZ groups.
