Wild grapes have been used as traditional medicinal use and alcoholic beverage production in Korea. The objective of this study is to improve antioxidant properties in Sae-muru by far infrared ray (FIR) treatment, with expecting potential benefits of FIR treatment for wild grape products during manufacturing processes. FIR treatment in berries induced increased content of catechin, epicatechin gallate, epigallocatechin gallate, gallic acid, rutin, ellagic acid, and resveratrol, while content of epicatechin and epigallocatechin was decreased. Although FIR treatment resulted either increased or decreased chemical component groups, presenting in HPLC chromatograms, antioxidant activity in Sae-muru extract was significantly increased by the FIR treatment. Our results suggest that FIR treatment should be an efficient process in the production of high content of bioactive molecules in Sae-muru.

Objective: The purpose of this study was to determine the effects of Puerariae radix(PR) herb-acupuncture on nitric oxide synthase(NOS) expression in hippocampus of alcohol-intoxicated Sprague-Dawley(SD) rats. Methods: SD rats were randomly assigned into 6 groups; normal group, control group, alcohol with herb-acupuncture group(0.3, 3, 30 and 300mg/kg PR). Normal groups were received with NaCl, while alcohol intoxication groups were injected intraperitoneally with alcohol(2g/kg) twice per day for 3 days. Herb-acupuncture groups were injected on Zhongwan(CV12) for 5 consecutive days. For the detection of NADPH-d-positive cells in hippocampus, immunohistochemistry was performed. Results: n control group, a significant decrease in NADPH-d-positive cells was observed compared to normal group. In alcohol with herb-acupuncture group, NADPH-d-positive cells increased significantly compared to control group. Conclusions: The present results revealed that NOS expression is enhanced in the hippocampus of SD rats through PR herb-acupuncture in an acute alcoholic intoxication condition.

최근, 유비쿼터스 관련 산업이 비약적으로 발전하고 있으며, 특정 구역을 대상으로 유비쿼터스 환경을 구축하는 u-Zone의 개발이 추진되고 있다. 특히 헬스케어 시스템의 관점에서 보면, u-Zone을 활용하여 정신질환자나 거동이 불편한 환자를 관리하기 위한 비용과 노력을 감축시킬 수 있다. 하지만 아직 헬스케어 시스템은 특정 개인을 대상으로 하거나 병원 내부 시스템을 확장하는 수준에 그치고 있다. 정신질환자 중에는 알코올, 마약 등의 약물에 중독된 환자의 비율이 높지만, 일상적인 데이터의 수집이 어려워 체계적인 관리나 정확한 진단이 어렵다. 따라서 본 논문에서는 u-Zone 내에서 중독환자에게 생체신호 측정 센서를 통해 지속적인 정보를 수집하고, 모니터링할 수 있는 시스템을 제안하였다. 맥박, 체온, 가속도 센서를 이용하여 환자 상태정보를 수집하고, 이를 기반으로 감정 상태를 판별하여 정확한 진단의 근거가 될 수 있도록 한다.

To consider potentially new sources which have hypoglycemic effect and accelerating alcohol detoxification, this study was designed to investigate the effect of Crataegus fructus and Morns alba L. in alcohol-treated rats. I compared the body weight, glucose, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alcohol dehydrogenase (ADH), and aldehyde dehydrogenase (ALDH) of rats administered both alcohol and extract of experimental plants to rats treated with alcohol alone. Administration of extracts of C. fructus and M alba, respectively, resulted in a significant reduction in the blood glucose level and the activities of ADH of liver compared to the control rats, and administration of extract of M. alba showed significantly lower on bodyweight gain in the rats than in other treated rats. In contrast, the activities of ALDH of liver were increased. The activities of AST and ALT between the only alcohol-treated rats and the alcohol and experimental plants-treated rats were no significant difference. The results suggest that C. fructus and M alba have a hypoglycemic effect, and reduce liver damage by accelerating acetaldehyde metabolism in alcoholic rats, so the combined effect of C. fructus and M alba may be considered as an alternative remedy for hangovers, alcohol-induced overweight and alcohol-induced diabetes.

To investigate constituents of Strobilomyces floccopus (Fr.) Karst. and Coprinus comatus (Fr.) S. F. Gray, free and total amino acids of the two mushrooms were quantitatively analyzed by G. L. C. and an amino acid analyzer. Free amino acids were extracted from both mushrooms with ethanol. Fourtenn free amino acids were detected from the ethanol extract of S. floccopus and fifteen free amino acids from C. comatus by G. L. C. And the dry carphopores of both mushrooms were hydrolyzed with hydrochloric acid and then the total protein amino acids were analyzed by A. A. A. Seventeen total amino acids were detected from each acid-hydrolysate of S. floccopus and C. comatus. Lipids were extracted from the carpophores of S. floccopus and saponified with alcoholic potassium hydroxide. The isolated sterols were subjected to G. L. C. and two sterols were detected. The isolated free fatty acids were methylated with diazomethane and subjected to column chromatography and G. L. C. Eleven saturated and nine unsaturated free fatty acids were detected from the carpophores of S. floccopus. The presence of these nutrient components shows that the two mushrooms can be utilized as edible ones.

Ethanol exerts different effects on hepatic cellular metabolism, depending mainly on the duration of its intake. In the presence of ethanol following an acute load, a number of hepatic functions are inhibited, including lipid oxidation and microsomal drug metabolism. In its early stages, chronic ethanol consumption produces adaptive metabolic changes in the endoplasmic reticulum which result in increased metabolism of ethanol and drugs and accelerated lipoprotein production. Prolongation of ethanol intake may result in injurious hepatic lesions such as alcoholic hepatitis and cirrhosis A number of such metabolic effects of ethanol are directly linked to the two major products of its oxidation; hydrogen and acetaldehyde. The excess hydrogen from ethanol unbalances the liver cell's chemistry. In the presence of excess hydrogen ions the process is turned in a different direction. In this study, it was attempted to observe the effect of ginseng saponins on alcohol Oehydrogenase(ADH), aldehyde dehydrogenase(ALDH) and microsomal ethanol oxidizing system(MEOS) in vivo as well as in vitro. Furthermore, the effect of ginseng saponin on the hydrogen balance in the liver and the hepatic cellular distribution of (1-14C) ethanol, its incorporation into acetaldehyde and lipids was also investigated. It seemed that ginseng saponin stimulated the above enzymes and other related enzymes in ethanol metabolism, resulting in a rapid removal of acetaldehyde and excess hydrogen from the animal body,

Brown rice flour (BRF) was treated with different carbohydrases (Viscozyme, Termamyl, Celluclast, AMG, Ultraflo, and Pentopan), and then aqueous alcoholic extracts (70% ethanol) from the treated RBF were examined for their phenolic compositions and antioxidant activities (ABTS and DPPH radical scavenging activity). All the carbohydrases tested induced significant increases in ABTS radical scavenging activity (2.1-3.0 times). Moreover, These enzymes increased the amount of extractable free phenolic acids by 10-15 times, especially for ferulic and p-coumaric acid. Among the enzymes tested, Pentopan which was active in arabinoxylan hydrolysis appeared to be most effective in increasing the free phenolic acid content and ABTS radical scavenging activity than other enzymes. Enzymatic hydrolysis of cell wall polysaccharides in BRF could be used as an effective procedure for raising the amount of extractable phenolic acids and thus increasing the antioxidant activity of BRF extract.

Taurine, 2-aminoethanesulfonic acid, is an abundant free amino acid present in brain cells and exerts many important biological functions such as anti-convulsant, modulation of neuronal excitability, regulation of learning and memory, anti-aggressiveness and anti-alcoholic effects. In the present study, we investigated to explore whether taurine has any protective actions against oxidative stress-induced damages in neuronal cells. ERK I/II regulates signaling pathways involved in nitric oxide (NO) and reactive oxygen species (ROS) production and plays a role in the regulation of cell growth, and apoptosis. We have found that taurine significantly inhibited AMPA induced cortical depolarization in the Grease Gap assays using rat cortical slices. Taurine also inhibited AMPA-induced neuronal cell damage in MTT assays in the differentiated SH-SY5Y cells. When the neuronal cells were treated with $H_2O_2$, levels of NO were increased; however, taurine pretreatment decreased the NO production induced by $H_2O_2$ to approximately normal levels. Interestingly, taurine treatment stimulated ERK I/II activity in the presence of AMPA or $H_2O_2$, suggesting the potential role of ERK I/II in the neuroprotection of taurine. Taken together, taurine has significant neuroprotective actions against AMPA or $H_2O_2$ induced damages in neuronal cells, possibly via activation of ERK I/II.

There is an increasing consumption of Makgeolli in both domestic and foreign markets due to a high interest in Korean traditional alcoholic beverages. However, currently, a standardized system of manufacturing, storing and circulating Makgeolli is not available. Therefore, manufacturing the constant quality of finished products is hardly achieved due to the uncertified quality index of Makqeolli. In particular, quality changes occur as a result of variable initial load of microorganisms during shelf life. Eight different commercially available brands of Makgeolli were obtained, and their initial concentrations of yeasts were measured. One brand with the highest concentration was chosen, and the variable initial concentrations were prepared at a concentration of $10^6{\sim}10^8$ yeast CFU/ml. These Makgeolli samples were heat-treated at 65, 70, 75 or $80^{\circ}C$. It was shown that temperatures higher than $75^{\circ}C$ were needed in order to pasteurize Makgeolli properly. In addition;it is considered that controlling the microorganisms by a standardized system for the processing analysis would improve the quality of Makgeolli.

Houttuynia cordata Thunb (HCT) is a native herb found in Southeast Asia which features various pharmacological activities against allergy, inflammation, viral and bacterial infection, and cancer. The aims of this study were to determine the cytotoxic effect of 6 fractions obtained from silica gel column chromatography of alcoholic HCT extract on human leukemic Molt-4 cells and demonstrate mechanisms of cell death. Six HCT fractions were cytotoxic to human lymphoblastic leukemic Molt-4 cells in a dose-dependent manner by MTT assay, fraction 4 exerting the greatest effects. Treatment with $IC_{50}$ of HCT fraction 4 significantly induced Molt-4 apoptosis detected by annexinV-FITC/propidium iodide for externalization of phosphatidylserine to the outer layer of cell membrane. The mitochondrial transmembrane potential was reduced in HCT fraction 4-treated Molt-4 cells. Moreover, decreased expression of Bcl-xl and increased levels of Smac/Diablo, Bax and GRP78 proteins were noted on immunoblotting. In conclusion, HCT fraction 4 induces Molt-4 apoptosis cell through an endoplasmic reticulum stress pathway.
