A dose, 1g/kg of ethanol produced experimental hyperuricemia in mouse. Ginseng saponins were tested for their ability to alter the hepatic xanthine oxidase activity and the blood level of uric acid in the ethanol-treated mouse. Intraperitoneal injection of ginseng saponin 4mg/kg markedly decreased the xanthine oxidase activity in the ethanol-treated mouse liver. It was also observed that ginseng saponin reduced the blood concentration of uric acid in experimentally induced hyperuricemia by alcohol treatment. In vitro, it was found that a low concentration of ginseng saponin in the reaction mixture incresed the hepatic xanthine oxidase activity, while a high concentration inhibited both enzyme preparations of normal and ethanol treated mice. In contrast with the xanthine oxidase, uricase activity was not influenced by ginseng saponin as well as in vivo. These results suggest there is a possibility that ginseng saponin may have some therapeutic effect on gout and other hyperuricemia syndrome.

The present study was aimed to investigate the effects of the application of pulsed electromagnetic fields on the blood components associated hyperlipidemia, antioxidant enzymes and reactive oxygen. The subjects were divided into three groups: General Diet, High fat Diet, High fat diet and pulsed electromagnetic fields. Pulsed electromagnetic field was applied with pulsed electromagnetic energy therapy equipment. The Glucose, free fatty acids, triglycerides, cholesterol and insulin was used to measure hyperlipidemia-related blood components, and the GSH, GRD, XO and MDA was used to measure antioxidant enzymes and reactive oxygen. The applied pulsed electromagnetic field has improved the concentrations of blood components and increasing GSH and GRD, that were decreased due to a high-fat diet and by reducing the increased MDA and XO to a level of general diet group. Therefore, the applied pulsed electromagnetic field can be the effective treatment for changes in the blood composition of hyperlipidemic rats, enhancement of antioxidative activity and the inhibition of reactive oxygen.

This study was performed to examine the increasing biological activities of both nerve growth factor induction and anti-aging activity of gastrodia (Gastrodia elata) with fermentation process. Antioxidant activities, taken in the fermenting, were investigated to verify utility value of gastrodia for functional food and cosmetics. Fermented gastrodia extracts showed higher antioxidant activities than dried gastrodia extracts. During the routine check of all the practical use potential as functional food, inhibition effect of angiotensin converting enzyme (ACE) and xanthine oxidase (XOase) was tested among water extracted dried gastrodia (WEDG), water extracted fermented gastrodia (WEFG), 70% ethanol extracted dried gastrodia (EEDG) and 70% ethanol extracted fermented gastrodia (EEFG). DPPH was shown as WEDG = $64.14{\pm}0.89%$, WEFG = $66.21{\pm}1.03%$, EEDG = $82.25{\pm}0.52%$, and EEFG = $82.36{\pm}2.37%$. ABTS was shown as WEDG = $54.15{\pm}1.37%$, WEFG = $60.24{\pm}2.25%$, EEDG = $59.18{\pm}1.86%$, and EEFG = $77.17{\pm}4.23%$. Therefore, ACE activity was dramatically inhibited by EERG while there was no difference of XOase inhibition between EEFG and EERG. Nerve growth factor (NGF) activity was measured and indicated about 40% increased neurite growth effect. To conclude, biologically active compounds of gastrodia were increased by fermentation process. It seems to be that ferment gastrodia enhance the use ranges from functional food to fuctional cosmetics, and to all processing industry.

Free radicals are thought to be the most important cause of the reperfusion injury subsequent to ischemia. The antioxidant status of the tissue affected by ischemia-reperfusion is of great importance for the primary endogenous defense against the free radical induced injury. Therefore, antioxidant therapy has been shown to be beneficial in neurological disorders such as Alzheimer's disease and cerebral ischemia. In this study, the protective effects of Chungpesagan-tang (CST) was investigated against ischemia/reperfusion-induced cytotoxicity in SK-N-MC neuronal cells It was found out that low concentration of CST was highly effective in protecting neuronal cells against ischemia/reperfusion-induced cytotoxicity. The inhibitory effect of CST on malondialdehyde formation during ischemia/reperfusion-induced oxidative stress in SK-N-MC cells showed obvious dose-dependent responses. Also, CST showed relatively high inhibitory activity to xanthine oxidase induced by ischemia/reperfusion environment Therefore, it is thought that CST has both antioxidant and xanthine oxidase inhibitory effect and can be used for clinical applications for protection of neuronal cells from ischemia-reperfusion injury.
