  • This study was undertatken to investigate the effects of dietary vitamin E on the toxicity of cadmium(Cd) in rats. The two variables were the supplmentary vitamin E(400lU/kg) and the protein amount(10.5% in the low protein diet and 18.0% in the normal protein diet) In cadmium treated rats net weight gain and food intake were decreased but improved by supplementation with vitamin E in the normal protein, hematocrit values reduced by Cd were significantly increased by the addition of vitamin E to normal protein diet in Cd intoxicated rats, The supplementation with vitamin E diminished the effect of Cd on aspartate aminotransf-rase and alanine aminotransferase activities in serum In Cd treated rats fed normal protein diet with vitamin E the contents of triglyceride were decreased and total-cholesterol contents were significantly reduced in serum and both of them in liver were markedly decreased. The activity of alcohol dehydrogenase in liver was decreased by Cd however supplementation with vitamin E reduced the effects of Cd on hepatic alcohol dehydrogenase. the results of this experiment indicated that there was some interaction between vitamin E and protein levels and supplementation with vitamin E had an effect more than protein levels oncd toxicity.

  • The kinds of volatiles in tomato fruits during storage were increased with the period of climacteric rise. The increasing and decreasing rate of their contents were slower under subatmospheric pressure-low temperature (SAP-L) than under normal atmospheric pressure-normal temperature (NAP-N). High contents of 2-hexanone, n-pentanol, and ethanol were decreased at the early period of storage and then increased. The content of n-octanol and furfural were increased, while that of n-butanol, cyclohexanone, and phenylacetaldehyde was decreased during storage. On the other hand, the content of trans, trans-2,4-decadienol, benzyl alcohol, and 2-heptanone was not changed during storage.

  • This study was carried out to find out the factors that influence the level of problem drinking of public aid recipients. The sample of this study consisted of 195 public aid recipients living in D and G cities. It was found that drinking is serious among the public aid recipients of which one third are in the state of problem drinking, alcohol abuse, or alcohol dependent. The hierarchical regression analysis revealed that first-drinking under the age of 19, self-esteem, religion, depression, and sex are the factors affecting the problem drinking of public aid recipients. Accordingly, it is necessary to develop a program considering these factors to prevent problem drinking of public aid recipients.

  • Diffusion tensor images were obtained for middle-aged men according to the AUDIT-K scale. As a result of the fractional anisotropy (FA) value of the gyrus nerve fibers in the brain region measured and analyzed by the Tract-Based Spatial Statics, FA values of general drinkers were measured lower than those of estimated alcohol use disabled people. This was statistically significant. In other words, the use of alcohol significantly affects the anatomic microstructural changes measured in the Gyrus of the brain region, and it may damage the nerve fiber tract and affect the functional abnormalities associated with it.

  • Objective: To evaluate the efficacy of sclerotherapy for conservative treatment of ovarian pseudocyst. Methods: Patients with ovarian pseudocyst who had undergone sclerotherapy at Ajou University Hospital from February, 1997 to March, 2002 were included in this study. Sclerotherapy was performed as follows: Under intravenous analgesia, the cyst was irrigated with dehydrated alcohol after aspiration under transvaginal sonography. The aspirated contents and alcohol irrigated contents were sent for cytologic examination. Results: 71 patients with ovarian pseudocyst were performed sclerotherapy. All but 2 patients were followed up for 0.5 to 33 months with transvaginal sonography and pelvic examination. Mean age of the patients was 40 years old. Mean size of the pseudocyst was 8.0 cm, mean amount of aspiration fluid was 179.8 ml, and average follow-up duration was 6.0 months. All had abdominal or pelvic surgical history and 38 patients (58.9%) of them had undergone hysterectomy. 44 of 71 patients (62.0%) were performed sclerotherapy only one time. 27 patients (38.0%) recurred and were undergone more than one time. Complication was not occurred in all cases. Conclusions: We concluded that although pseudocyst after sclerotherapy has high recurrence rate, sclerotherapy was an safe and effective method for conservative treatment of ovarian pseudocyst.

  • Poly(vinyl alcohol)(PVA) nanocomposite films containing various saponite (SPT) clay contents were synthesized using a solution intercalation method. The thermal property, morphology, optical transparency, and gas permeability of the PVA nanocomposite films with various SPT contents in the range of 0 to 10 wt% were examined. PVA nanocomposite film containing 5 wt% SPT showed excellent thermal and gas barrier property. The hybrid films containing 5 wt% SPT were equibiaxially stretched with stretching ratios ranging from 150 to 250%. The clay dispersion, optical transparency, and gas permeability were also examined as a function of equibiaxial stretching ratio. The PVA nanocomposite films with various equibiaxial stretching ratios showed excellent optical transparency and barrier to oxygen permeability.

  • Fermentation characteristics and quality changes of the typical Korean traditional alcoholic beverages (Kwahaju, Sokokju, Baikhaju, Samhaeju and Hosanchun) were investigated during fermentation and after aging, respectively. They were prepared by their own brewing methods with respect to the same contents of rice and Nuruk (Korean-style bran koji). The consumed total sugar content of the alcoholic beverages (Sokokju, Baikhaju, Samhaeju and Hosanchun) which were brewed with the multiple input steps of seed mash and raw material (ABMIS) was higher than that of the alcoholic beverage (Kwahaju) which was brewed with the single input step (ABSIS). The pH values of all the beverages were similar and were ranged from 3.2 to 3.6. The acidity of ABMIS were lower than that of ABSIS, but alcohol concentration of ABMIS were higher. The fermentation period of the alcoholic beverages with triple input steps was the longest among them. The inner temperature and microbial growth in all the beverages increased at each of input steps of the raw materials. Fusel oil content of ABMIS was lower than that of ABSIS. Major components of the fusel oil were iso-amyl alcohol, iso-butanol, n-propanol, ethyl acetate and acetaldehyde, and its minor components were methanol and n-butanol. The results on quality changes of the alcoholic beverages after aging showed increase of alcohol in ABMIS, but decrease of sugar and acidity. Fusel oil contents of Kwahaju and Samhaeju decreased to be ranged from 3.1% to 13.9% after aging, but those of Sokokju, Baikhaju and Hosanchun increased to be ranged from 10.9% to 23.0%. Sensory evaluation of ABMIS showed better scores than that of ABSIS. It was suggested that the brewing method with multiple input steps of seed mash and raw material was one of the methods to increase fermentation efficiency for brewing the Korean traditional alcoholic beverages.

  • 100 different yeast colonies were isolated from spontaneously fermented kiwis, persimmons, apples, pears, watermelons, grapes, grape fruits, peachs, and plums, and selected yeast strains were used to produce kiwi-persimmon mixed wine (KPMW). Among the isolates, five representative strains exhibited tolerance to sucrose, alcohol, pH, and potassium metabisulfite when compared with the control yeast strain (Saccharomyces cerevisiae KCCM 12615). All five yeast strains (Y4, Y10, Y28, Y78, and Y81) exhibited 99% 26S rDNA sequence similarity to S. cerevisiae. The pH, acidity, Brix, reducing sugar, alcohol, and organic acid contents were consistent in KPMW prepared from the S. cerevisiae KCCM 12615 and Y28 strains. KPMW made from the Y4, Y10, and Y28 strains exhibited lower quantities of free sugars than those of the KPMW made from the other yeast strains. The level of ethyl esters in KPMW prepared from the Y28 was higher than that in the other KPMWs. All strains, except for Y28, produced lower concentrations of sulfur and ketone compounds. Furthermore, the KPMW produced by the Y28 strains had total phenolic contents with 1.1 g/L, with DPPH and ABTS radical scavenging activities of 57.06% and 55.62%, respectively, and a FRAP assay value of 0.72. Our results suggest that Y28 is a promising yeast strain for producing high-quality wines.
