  • Tenderization of beef by the addition of barks(Morus alba Linne) and its sensory properties were observed by shearing test, cooking loss, pH, protein content and sensory evaluation. Shear force was decreased as the addition level of barks (Morus alba Linne) increased. Tenderization effect of beef was increased 8,8% at the addition level of 2.5%, 25% at 5.0%, 4.7% at 7.5%, 58% at 10% barks(Morus alba Linne). Cooking loss was observed 44.50% at the no addition, 45.3% at 2.5%, 45.8% at 5.0%, 47.5% at 7.5%, 50.0% at 10% addition level of barks (Morus alba Linne). As the addition level of barks(Morus alba Linne) increased pH of cooked beef decreased to the range of 5.6 to 5.46. As the addition level of barks (Morus alba Linne) increaed protein content of beef decreased whereas protein content of cooled liquor increased. The addition of barks(Morus alba Linne) improved the sensory quality of cooked beef. Especially, tenderness scored the highest value in 10% added beef and other quality factors color, flavor, juiciness and overall quality were evaluated significantly high in 5% added beef. Therefore 5% addition level of barks(Morus alba Linne) for cooking beef was suggested as the desirable level of addition.

  • Objective : The purpose of this study was to compare the plasma amitriptyline and nortriptyline level between before and after fluoxetine addition with patients who were currently taking amitriptyline. Method : From the inpatient and outpatient unit of Soon Chun Hyang University Hospital, Chunan, fourteen subjects who were taking amitriptyline 25mg more than 1 week at least were given fluoxetine 20mg. Before and 2 weeks after fluoxetine addition, the plasma level of amitriptyline and nortriptyline are analyzed simultaneously by High Performance Liquid Chromatography(HPLC). At the same times, HAM-D(Hamilton Rating Scale for Depression) score and the UKU(Uldvalg for Klinske Unders${\Phi}$ gelser) side effect scale were checked. Results : After fluoxetine addition to the patients who were taking amitriptyline, the plasma level of amitriptyline, nortriptyline and sum of amitriptyline and nortriptyline had risen. The mean plasma amitriptyline level increased from $168.9{\pm}89.4ng/ml$ to $183.0{\pm}102.0ng/ml$ after fluoxetine addition(p=0.011), but the change was not statistically significant. The mean plasma nortriptyline level increased significantly from $114.3{\pm}70.2ng/ml$ to $168.0{\pm}86.2ng/ml$ after fluoxetine addition(p=0.011). In addition, the mean plasma level of total amitriptyline and nortriptyline increased significantly from $283.1{\pm}125.3ng/ml$ to $350.9{\pm}78.4ng/ml$ after fluoxetine addition(p=0.016). After fluoxetine addition, no significant change was noted in the UKU side effect scale score. Conclusion : As consequence of comparison of plasma amitriptyline and nortriptyline level before and after fluoxetine addition, mean amitriptyline, nortriptyline and total plasma level was increased after fluoxetine addition. This suggests that coadministration of amitriptyline and fluoxetine may induce improvement of depressive symptom in depressive patients by way of increased plasma level of amitriptyline.

  • The purpose of this study was to investigate the effects of different moisture addition and sugar on the quality of Nokcha-julpyun, during 24hrs. As the result of the Hunter's color values, lightness, redness and yellowness were increased slightly or not after 24hrs and showed middle levels in $30%{\sim}40%$ moisture addition groups. It seemed that the addition of sugar to Nokcha-julpyun affected the redness and yellowness of 40% and 45% moisture addition groups more than the other groups. In texture profile, springiness of Nokcha-julpyun was not different significantly among all the groups during storage. Cohesiveness was getting higher by increase of moisture level and getting lower by storage. Sugar addition seemed to lower the rate of decrease of cohesiveness. Chewiness and hardness were getting lower by increase of moisture level and getting higher during storage. In this case sugar addition seemed to interfere the Nokcha-julpyun to be hard. Adhesiveness showed to be decreased during storage, but didn't show any correlations with water level. Sugar addition to Nokcha-julpyun seemed to increase springiness and adhesiveness slightly. 35% moisture and sugar addition group had the lowest values in springiness, hardness and cohesiveness. Both 40% groups and 45% moisture and sugar addition group had high values in springiness, cohesiveness and adhesiveness but had the lowest values in hardness and chewiness. In sensory evaluation, $30%{\sim}40%$ moisture addition groups showed good preferences in color, flavor, taste, tenderness and chewiness, and the 35% moisture and no sugar addition group showed the best overall acceptance among the groups. Above results indicated that moisture addition level with $30%{\sim}35%$ seems to give the best quality to Nokcha-julpyun added green tea powder with 6% level, and for the purpose to reduce the changes of texture profiles during storage, it is benefit to add sugar a little to Nokcha-julpyun.

  • Effect of molasses addition to complete calf starter (CCS) and the following pellet processing was evaluated with 12 Holstein-Friesian (HF) calves (7-14 d old with $42\;{\pm}\;5.5\;kg$ average BW), with 6 calves (replicate) per treatment. The CCS was formulated with 65% concentrate calf starter and 35% local corn fodder. On the CCS, molasses was added either 5% (M5) or 10% (M10), then the mixture was pelleted and fed to the calves for 7 weeks. Molasses addition, regardless of addition level, improved (p<0.05) both the durability and hardness of the pellet which contains 35% of high fibrous local corn fodder. Upon feeding to calves, the feed intake and daily gain were numerically higher with 5% molasses addition compared to 10% molasses addition. Blood VFA level was remarkably higher (p<0.01) in calves fed M10 than calves fed M5. There was no difference (p>0.05) in blood glucose level between M5 and M10. Length and number of papillae were not different (p>0.05) by the addition levels of molasses. However, there was one exception in number of papillae at caudo-dorsal sac which were higher (p<0.05) number in M5 than M10 calves. Considering the quality of CCS pellet, calf performance and rumen development, there was no additional benefit of 10% molasses addition compared to 5%. From the results of this study, 5% molasses addition could be recommended for local farmer when they utilize local corn fodder to make CCS for HF calves in Indonesia.

  • Effects of addition of a mycotoxin detoxifier in poultry feed were studied in broilers. Aflatoxins were present in the poultry feed as 28 ppb (normal feed), 78 ppb (contaminated feed) and 170 ppb (highly contaminated feed). The mycotoxin detoxifier was used in 3 concentrations i.e. 1, 3 and 5 kg/ton of feed. Aflatoxins reduced the body weight in broiler chicken and treatment of contaminated feed with low level of detoxifier improved the body weight equivalent to that of normal feed. Higher level of detoxifier proved better than lower level addition in alleviating the effects of highly contaminated feed. Addition of detoxifier also resulted in improvement of FCR to the level of normal feed. Antibody levels against Newcastle disease virus on day 28 of age were significantly lower in chicken fed on contaminated feed. Addition of detoxifier in feed improved the antibody levels in chicken. Mortality was highest in groups given contaminated feed throughout the study period of 7 weeks. Significant mortality was also observed in groups given highly contaminated feed for 2 weeks. Mortality in chicken given detoxifier added contaminated feed was lowest and similar to the group given normal feed. The study shows that mycotoxin detoxifier containing oxyquinol, dichloro-thymol and micronized yeast can effectively neutralize the ill-effects of aflatoxins in poultry feed.
