The objective of this study was to investigate the quality characteristics of Baeksulgi (BS) and Sulgidduk added with Makgeolli (MS, BS+ Makgeolli) during storage at $20{\pm}2$ for 3 days. Moisture contents of MS were significantly higher than those of BS during storage. Reducing sugar contents (%) were higher in MS. The pH values were 6.23 and 5.93, for BS and MS, respectively. The pH of MS was lower and thus indicated higher in acidity. The Hunter color L (lightness) and a (redness) values were higher for BS, whereas b (yellowness) value of MS was lower. In the texture analysis, hardness and chewiness of MS were found to be lower, whereas springiness, gumminess, and resilience were higher than those of MS. According to DSC (Differential scanning calorimeter) analysis, enthalpy of MS appeared to be lower than that of BS during storage, which suggests retrogradation of MS was delayed. The total phenol content was higher in MS. The $IC_{50}$ value of DPPH and hydroxyl radical scavenging activity was lower in MS, which means antioxidant activity increased in MS. Results of the preference test showed that appearance, flavor, taste, and overall acceptability of MS scored higher than those of BS. From these results, high quality of MS was derived from Makgeolli addition.

A gas chromatographic method using nitrogen phosphorous selective detection was developed for simultaneous determination of haloperidol and its metabolite, reduced haloperidol, in human plasma. Combelen was used as internal standard, The method involved extraction and trimethylsilylation followed by the injection of $2-4\;{\mu}l$ of benzene layer, which was used to dissolve the trimethylsilylated derivatives of haloperidol and reduced haloperidol, onto SE-54 column [5% phenyl methyl silica fused capillary column, $16m{\times}0.22\;mm$ $(I.D.){\times}0.33\;{\mu}m$ (coated thickness)]. The temperature of column oven was programmed from $200^{\circ}C\;to\;300^{\circ}C$ at the increase rate of $10^{\circ}C/min and also the temperatures of injector and detector were set at $300^{\circ}C$. Helium was used as carrier gas and its flow rate was maintained at 30 ml/min. The detection was conducted with nitrogen phosphorous selective detector. The retention times for combelen, reduced haloperidol and haloperidol were found to be 9.14, 9.75 and 9.99 min, respectively. The detection limits for haloperidol and reduced haloperidol in human plasma were both 0.2 ng/ml. The coefficients of variation of the intra-assay were generally low (below 9.8%). The mean absolute recoveries of added haloperidol and reduced haloperidol from plasma were 72% and 84%, respectively. No interferences from endogenous substances were found.

Application of genotype by environment ($G\;{\times}\;E$) interaction would be used for identifying optimum test condition of the varietal adaptation in the establishment of breeding purpose. Yield and yield components were used to perform additive main effect and multiplicative interaction (AMMI) analysis. Significant difference for $G\;{\times}\;E$ interaction were observed for all variable examined. For yield, 0.18 of total sum of squares corresponded to $G\;{\times}\;E$ interaction. Correlation analysis was carried out between genotypic scores of the first interaction principal component axis (IPCA 1) for agronomic characters. Significant correlations were observed between IPCA 1 for yield and capsule bearing stem length (CBSL), number of capsule per plant (NOC). The biplot of grain yield means for IPCA1 which accounted for 34% of the variation in total treatment sums of squares showed different reaction according to $G\;{\times}\;E$ interaction, genotypes and environments. Taegu showed relatively lower positive IPCA1 scores, and it also showed smaller coefficient variation of yield mean where it is recommendable as a optimal site for the sesame cultivar adaptation and evaluation trial. In case of variables, Yangbaek and M1 showed relatively lower IPCA1 scores, but the score direction showed opposite each other on the graph. Ansan, Miryang1, Miryang4, and Miryang6 seemed to be similar group in view of yield response against IPCA1 scores. These results will be helpful to select experimental site for sesame in Korea to minimize $G\;{\times}\;E$ interaction for the selection of promising genotype with higher stability.

The purpose of this study was to evaluate the quality characteristics and antioxidant activity of chocolate added with Rehmannia Radix Preparata (R. Radix Preparata) concentrate (0, 3, 6 and 9%). As the amount of R. Radix Preparata concentrate increased, water content significantly. The pH of chocolate decreased significantly as R. Radix Preparata concentrate increased, but the acidity of chocolate increased. Sugar concentration and reducing sugar contents also increased according to the amount of R. Radix Preparata concentrate. The L(lightness), a(redness) and b(yellowness) values significantly decreased as R. Radix Preparata concentrate increased. However, texture was not significantly different among the treatments. As the amount of R. Radix Preparata concentrate increased, DPPH radical scavenging and hydroxyl radical scavenging activities increased. In the results of the sensory evaluation, scores of color, taste, flavor, texture, and overall acceptability were the highest in chocolate added with 6% R. Radix Preparata concentrate. From these results, it was suggested that the optimum addition amount of R. Radix Preparata concentrate to chocolate is 6%.

Objectives : The purpose of this study was to investigate the effect of Poncirus Trifoliata(PT) on improvement of fecal impaction in spinal cord injured(SCI) rats. Methods : Fifteen adult Sprague-Dawley female rats were used weighing 200~250 g. A complete spinal cord transection was performed surgically at the T10 cord level. Experimental groups were assigned into 3 groups: Control(n=5), SCI+vehicle(n=5) and SCI+PT(n=5). PT was administered 100mg/kg in 0.5ml every 24 hours from 1st operation day to 7th day. We measured the body weight and food intake as well as the number and the weight of fecal pellet every morning. After 1 week of operation, whole colon was divided into proximal and distal segments under anesthesia. Each segment of colon was mounted with longitudinal direction in a organ bath. We measured spontaneous contraction and compared the area under the curve in each segments. Enhanced responses were observed by acetylcholine($10^{-6}M$), 40 mM KCl solution, L-NAME($10^{-4}M$). Results : The fecal number and weights were significantly higher in the group of SCI+PT than SCI+vehicle group(p<0.05). In organ bath study, area under the curves of the spontaneous contraction in SCI+vehicle and SCI+PT groups were significantly increased compared to control group. Contractility of distal colon in response to acetylcholine or KCl in SCI+vehicle group was significantly decreased compared to other groups(p<0.05). Conclusions : These results suggest that PT might be useful to promote bowel emptying in spinal cord injured rats.

Inhibitory activity of pesticide-preventing active carbon fiber mask on the penetrations in pesticide spray and its inhibitory effect on acute inhalation toxicity in rats were s tudied. Pesticides were sprayed into box ($1.O{\times}1.2{\tmies}O.6\;m$) at a dose of 20ml/min of diazinon ($Diatone^{TM}$) suspension (340ppm) and 5g/min of BPMC powder (2.0%) for 4 hours, and then captured the penetrated pesticides into water via mask in box under 8l/sec suction. The pesticides were analysed by A.O.A.C. method and GC/MS. Pesticide-preventing active carbon fiber mask significantly inhibited the penetration of diazinon by 93.4% as compared with control, and cotton mask and pesticide-preventing mask did it by 74.2% and 83.7%,respectively. This result shows that pesticide-preventing active carbon fiber mask has the most prominent inhibitory effect in preventing the penetration of diazinone. In the penetration of BPMC, all of three masks, such as active carbon fiber mask, cotton mask and pesticide-preventing mask, have a similar inhibitory effect, which were 99.3%, 98.6% and 97.0%, respectively. The penetrated pesticides via pesticide-preventmg active carbon fiber mask did not exert acute inhalation toxicity.
