Chromatographic separation of Laduca raddeana extract afforded a mixture of fatty acyl triterpene, triterpene acetates and primary long chain alcohol. The kind of triterpene moieties in these two triter­penoids was six, i.e., ${\beta}-amyrin,\;{\alpha}-amyrin$, lupeol, pseudotaraxasterol, taraxasterol and germanicol on the basis of chemical and spectroscopic methods. The acyl moieties in the corresponding acyl mixture were characterized as acetates, myristate, palmitate, stearate and arachidate. And a mixture of primary long chain alcohol were composed of teracosanol and hexacosanol.

The regulation of the synthesis of alcohol-oxidase (E.C.1.1.3.13.) was investigated in the methanol-utilizing yeasts during growth on different carbon sources. For this experiment, Hansenula polymoypha CBS 4132, Hansenula polymoypha CBM 11 and Hansenula polymoypha Cooney were cultured in mineral salt medium by changing its carbon sources. The production of alcohol-oxidase was varied by the carbon sources. For exmaple, alcohol-oxidase was undetectable: in all strains submitted to the test in the medium with glucose, but its production was rapidly increased when the carbon source was changed from glucose to methanol after 30 hrs of incubation. Moreover, this enzyme was not synthesized during growth on the primary aliphatic alcohols alone (ethanol, propanol, butanol or pentanol) or on the mixed substrates (0.5% methanol + 0.5% primary aliphatic alcohols). When cells were grown on the various carbon sources (glucose, xylose, lactose, glycerol, galactose, saccharose, sorbose, lactic acid or acetic acid), the alcohol-oxidase was about one-tenth of the activity found in cells grown on methanol alone. These carbon sources together with methanol yielded far better synthesis of alcohol-oxidase than in case of carbon sources alone. Especially, the alcohol-oxidase activity of the cells grown on lactose or lactic acid together with methanol was far better or similar than that of cells grown on methanol alone. The synthetic activity of alcohol-oxidase of Hansenula polymoypha CBS 4132 was the strongest among the three strains tested in every respect.

Methanol assimilating yeast, Hansenula sp. MS-364 that has high productivity with methanol as carbon and energy source has been preserved at dept. of Microbiological engineering. Purification and properties of alcohol oxidase (E.C.1.1.3.13: oxygen oxidoreductase) were investigated in the methanol assimilating yeast, Hansenula sp. MS-364. Alcohol oxidase is related to the catalytic reaction that degrades alcohol to aldehyde and peroxide. The methanol oxidizing enzyme was purified by ammonium sulfate precipitation, DEAE-Sephadex A-50 chromatography and gel filtration on Sepharose 6B from cell-free extract. The purified enzyme preparation gave a single band in the sodium dodesyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). The molecular weight of the enzyme was calculated to be about 576,000 and molecular weight of subunit was also calculated to be 72,000. The optimal pH and temperature of the enzyme reaction were pH 7.5 and 37$\circ$C, respectively. The enzyme was unstable in acidic pH and higher temperature. The enzyme was not specific for methanol and also oxidized lower primary alcohols. The Km value for methanol was 2.5 mM and that for ethanol was 1.66 mM. The enzyme was heavily inhibited by metal ions such as Hg$^{2+}$, Ag$^{2+}$, Cu$^{2+}$. The high concentration of EDTA and sulfhydryl reagents strongly inhibited the enzyme activity. The component of coenzyme was determined to flavin adenine dinucleotide.

Hovenia dulcis which is distributed in Korea, China and Japan is known to show hepatoprotctive effect and reduce the acute alcohol toxicity. In this study, the hepatoprotective effect against the chemically induced experimental liver injury models and lowering effect of blood alcohol level in animal models acutely administered alcohol by the peduncle extracts of Hovenia dulcis var. koreana were investigated. HdfHW-1, and HdfM-1 which are the extracts of fruit peduncles and young branches with hot water or 70％ methanol and followed with 100％ methanol, were significantly reduced the $CCl_4$ or D-galactosamine/LPS induced damage in sliced liver. The hot water or methanol extracts of fruit peduncle protected dose-dependently against $CCl_4$ induced toxicity in primary hepatocyte culture and particularly, the amount of LDH release was reduced to the control level at 500 $\mu\textrm{g}$/ml of hot water extracts. HdfHW-1 also decreased the hepatotoxicity induced by $CCl_4$ in rats. The active components of HdfHW-1 seemed to be high molecular weights because 0.2 M NaCl HdfHW-1 fraction was the most effective among NaCl fractions of HdfHW-1 eluted with various concentrations of NaCl on DEAE 650C column chromatography. HdfM and HdfHW were significantly reduced the levels of blood alcohol in rats and mice administered 40％ alcohol. These results indicated that the hot water or methanol extracts of fruit peduncle of Hovenia dulcis var. koreana have hepatoprotective effect and may be reduce alcohol toxicity.

Ile-269 in horse liver alcohol dehydrogenase isoenzyme S(HLADH-S) was mutated to serine by phosphorothioate-based site-directed mutagenesis in order to study the role of the residue in coenzyme binding. The specific activity of the mutant(1269S) enzyme to ethanol was increased 49-fold. All turnover numbers of 1269S enzyme toward 9 primary alcohols were increased. The mutant enzyme showed 3.6, 4.6, 11.6-fold higher catalytic efficiency for $5{\beta}$-androstane-3, 17-dione, $5{\beta}$-cholanic acid-3-one and retinal than wild-type, respectively. The reaction mechanism of 1269S enzyme was ordered bi bi as wild-type's. These results indicate that the hydrophobic interaction of Ile-269 residue with coenzyme plays an important role in dissociation of coenzyme from enzyme-coenzyme complex, which has been known as the rate limiting step of ADH reaction.

Lifestyle and dietary behavior intervention as the primary prevention of lipid disorder seems safe and compatible with other treatments of cardiovascular diseases. Cross-sectional associations between lifestyle factors and dietary behavioral factors with plasma lipid and lipoprotein levels were analyzed in 189 middle-aged men in Suwon, Korea. Overnight fasting plasma levels of total cholesterol, high-density lipoprotein(HDL)-cholesterol, triacylglycerol and glucose were analyzed. Blood pressure and anthropometric data were also measured. Lifestyle factors such as smoking status, alcohol consumption and frequency of physical exercise were evaluated by a self-administered questionnaire. Questions regarding dietary behavior were also asked. The subjects were 43.8%${\pm}$7.9 years old, and 23.8%${\pm}$2.6kg/m$^2$. From stepwise regression analyses, significant correlates with total cholesterol level were body mass index(BMI), alcohol intake(negative), age and coffee drinking(model R$^2$=14.3%). BMI, breakfast-skipping, age, and sleeping hours were significant for triacylglycerol level(model R$^2$=15.8%). BMI, alcohol drinking(negative), age, and coffee drinking were significant for low-density lipoprotein(LDL)(model R$^2$=11.7%). Age(negative), BMI(negative), alcohol drinking, stress level(negative), physical exercise, and cigarette smoking(negative) were significant for high-density lipoprotein(HDL)(model R$^2$=12.1%). From stepwise regression analyses, excluding BMI and age as factors in the model, alcohol intake(negative) and coffee drinking were significantly correlated with total cholesterol level(model R$^2$=4.4%) : breakfast-skipping with triacylglycerol(model R$^2$=3.2%) : alcohol intake (negative) with LDL level(model R$^2$=3.4%) : alcohol intake, physical exercise and stress level(negative) with HDL level(model R$^2$=6.3%). The findings suggest that a healthy daily lifestyle and dietary behavior may have an anti-atherogenic effect by altering plasma lipid and lipoprotein levels in middle-aged Korean men.

Purpose: We have implemented a multi-disciplinary Screening, Brief Intervention and Referral to Treatment (SBIRT) protocol to prevent individuals who sustained alcohol-related traumatic injuries. We therefore conducted this single-center, prospective, randomized, controlled trial (RCT) to assess its efficacy. Methods: All the enrolled patients (n=30) were randomized to either the SBIRT group or the control group. In the current RCT, the proportion of the patients who reduced the amount of alcohol consumption and those who received a specialized treatment served as primary outcome measures. Moreover, changes in a 3-item version of the Alcohol Use Disorders Identification Test Consumption (AUDIT-C), Severity of Dependence Scale (SDS) and Kessler Psychological Distress Scale (K-6) scores at 3 months from baseline served as secondary outcome measures. Results: At 3 months, the proportion of the patients who reduced the amount of alcohol consumption was significantly higher in the SBIRT group as compared with the control group (86.7% vs. 57.1%, p=0.02). Moreover, the proportion of the patients who received a specialized treatment was also significantly higher as compared with the control group (26.7% vs. 1.4%, p=0.01). Furthermore, there were significant differences in changes in the AUDIT, SDS and K-6 scores at 3 months from baseline between the two groups (p<0.05). Conclusions: In conclusion, our results indicate that the SBIRT is effective in reducing hazardous and harmful levels of drinking, the degree of alcohol dependence and that of psychological distress in at-risk drinkers.
