Purpose: This study was performed to evaluate the effect of low-dose lidocaine on fentanyl-induced cough and hemodynamic changes under general anesthesia. This research was a randomized trial design and performed using a double-blind method. Methods: Data collection was performed from October 22, 2008, to May 4, 2009. One hundred and thirty two patients were randomly assigned to control group (Con G) and experimental group (Exp G) using a table of random numbers. Exp G (n=66) were administered 0.5 mg/kg lidocaine and Con G (n=66)) were administered saline. The occurrence of cough and vital sign were recorded within one minute after fentanyl bolus by an anesthesiologist. Collected data were analyzed using Repeated measures ANOVA using SPSS for Windows (Version 17.0). Results: The incidence of cough in Exp G was 13.6%, while Con G was 53%. The incidence cough in Exp G was significantly lower compared to Con G (p<.001). Lidocaine seemed not to suppress mean arterial pressure (p=.145), heart rate (p=.508), and oxygen saturation (p=.161). Conclusion: Intravenous administration of 0.5 mg/kg lidocaine seems to suppress fentanyl-induced cough without affecting mean blood pressure, heart rate and oxygen saturation. Therefore, we recommend intravenous 0.5 mg/kg lidocaine administration to suppress fentanyl-induced cough under general anesthesia.

Forty three 7-month old, Barbados Black $Belly{\times}Malin$ crossbred sheep were used for the trial. They were allotted into three treatment groups fed varying levels of oil palm (Elaeis guineensis) frond pellets and commercial sheep pellets. Treatment diets were 80% commercial pellet+20 % (% w/w) oil palm frond pellet (CON group, n=15), 50% commercial pellet+50% oil palm frond pellet (% w/w) (HAF group, n=14) and 80% oil palm frond pellet+20% (% w/w) commercial pellet (OPF group, n=14). The plasma fatty acid profiles from these animals were compared before and after 14 weeks of feeding. Results showed that total unsaturated fatty acid content in the CON group had increased by 10% (p<0.01) from the pre-treatment values. All three treatment groups had significantly different plasma n-6 and n-3 polyunsaturated fatty acid contents at the end of the trial. In fact, the CON group had significantly (p<0.01) more n-6 polyunsaturated fatty acid content compared to its own initial values, and also the values from the HAF and OPF groups. However there was a significant (p<0.01) decline in plasma n-3 polyunsaturated fatty acids in all groups. The final total unsaturated to saturated fatty acid content ratio was significantly (p<0.01) highest in the CON group, demonstrating the high plasma unsaturated fatty acid content in these animals. This study shows the plasma unsaturated fatty acids in sheep can be increased by dietary manipulation.

This study was conducted to investigate the quality of pumpkin paste added with different starches during storage at $4^{\circ}C$ for 8 days. Pumpkin paste was evaluated for pH, carotenoid, syneresis, color values, texture, and sensory characteristics. The properties of the pumpkin paste were studied on three different starches (CON: control, MCP: cow pea starch, MMB: mung bean starch, and MSP: sweet potato starch). The initial pH of the pumpkin paste with starches were 6.13~6.16. The pH of pumpkin paste increased as the starches added increased. The carotenoid content of CON was higher in the pumpkin paste processing. The change of syneresis significantly increased with the storage period, and the amount of change of MCP and MMB added with starch was smaller than CON without the added starch. The Hunter's L-values of the pumpkin paste increased, whereas the a- and b-value decreased as the amount of starches added increased. The results of the textural analysis showed that the hardness of MCP and MMB was different from that of other pumpkin paste, showing a lower value such as 38.26 g, 38.93 g, while CON and MSP was 40.43 g and 42.49 g, respectively. A sensory evaluation indicated that starches could enhance the overall texture characteristics of pumpkin paste. In terms of the overall acceptance of the pumpkin paste, the experimental group with MCP scored the best.

The purposes of this study were: (1) to examine the quality characteristics of the Sulgidducks added with barley sprouts by blanching (CON), freeze-drying (FBP), hot-air drying(HBP); (2) to examine the quality characteristics of Sulgidduck such as the moisture content, the color value, the textural properties and the sensory evaluation; (3) to find the optimal ratio of barley sprouts, which were made by the three different drying methods. As a result, the Sulgidduks containing barley sprouts by CON showed a lot of significance and high correlation depending on the amounts of the barley sprout(p<0.05). As the amounts of CON, FBP and HBP increased, the L and the a values of Sulgidducks significantly decreased, whereas the b values of them increased. For the textual properties of the Sulgidducks, on the first day, the concentration in CON up to 6% showed no significant differences in the hardness, cohesiveness, springiness, and chewiness. In case of FBP, the increase in the additives caused decrease in the hardness, adhesiveness, springiness, and chewiness of the Sulgidducks on storage 0 day(p<0.05). As the amounts of HBP increased, the hardness, springiness of the Sulgidducks on the first day decreased(p<0.05). Conclusionally, 6% blanched barley sprout added group, 2% FBP and HBP were highly rated in color, flavor, bitterness, chewiness, overall acceptability and all sensory quality characteristics.

The objective of this study was to investigate the utilization of diacylglycerol (DAG) as a new dietary ingredient replacing fish oil in feed for juvenile olive flounder Paralichthys olivaceus. Fish oil based control diet (CON) was prepared and four other diets were formulated by replacing 50% of the fish oil in CON with one of five DAG: DAGL (1,3-lauryl glycerol) or DAGP (1,3-palmityl glycerol) in low or high concentrations (designated as DAGLL, DAGLH, DAGPL and DAGPH). Another diet was prepared replacing 100% of the fish oil in CON with a 1:1 mixture (DAGLP) of DAGL and DAGP. Olive flounder (13.4 g) were fed to apparent satiation, twice a day, for 12 weeks. Following the feeding trials, no significant differences were observed in growth performance, blood parameters and non-specific immune responses between CON and any of the DAG groups. Polyunsaturated fatty acid levels were not significantly affected by the inclusion of DAGs. Thus, DAGL or DAGP could be used to replace up to 50% of fish oil in fish feed without reducing growth performance, health or innate immunity. The replacement of up to 100% of dietary fish oil in olive flounder feed by DAGLP is also feasible.

This experiment was conducted to evaluate the effects of dietary protease on growth performance, blood constituents, and carcass characteristics of growing-finishing pigs. A total of 48 growing pigs (initial body weight, $34.8{\pm}0.62kg$) were randomly assigned to 2 dietary treatments (6 pigs/pen; 4 replicates/treatment). The treatments were a diet based on corn and soybean meal (CON) and CON supplemented with 0.01 % of protease (PRO). Pigs were fed respective dietary treatments with a 2-phase feeding program for 12 weeks. Pigs fed PRO had higher average daily gain (ADG; phase I, 866.38 vs. 821.75 g/d; overall, 910.96 vs. 866.30 g/d; p < 0.05) and gain to feed ratio (G:F; phase I, 0.345 vs. 0.363 g/g; p < 0.05) than those fed CON. However, there were no differences on blood constituents and carcass characteristics between CON and PRO of growing-finishing pigs. In conclusion, dietary protease supplementation in the typical diet for growing-finishing pigs improved growth rate.

This study aimed to determine the blood lipid profiles, fatty acid composition, and lipogenic enzyme activities in rat adipose tissues as affected by the Angus beef fat (ABF) and Hanwoo beef fat (HBF) containing high oleic acid (OA) content. We assigned 60 Sprague Dawley rats with a mean bodyweight of 249 ± 3.04 g to three groups (n = 20 each) to receive diets containing 7% coconut oil (CON), 7% ABF, or 7% HBF. The OA content was highest in the HBF (45.23%) followed by ABF (39.51%) and CON (6.10%). The final body weight of the HBF-fed group was significantly increased, probably due to increased feed intake, indicating the palatability of the diet. The HBF and ABF significantly increased high-density lipoprotein cholesterol (HDL-C), decreased triglyceride (TG) and total cholesterol (TC) levels, and also tended to attenuate glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) levels in the bloodstream of the rats compared to CON. As compared to CON, lauric, myristic, and palmitic acids were significantly lower, and those of OA and α-linolenic acid (ALA) were significantly higher in the adipose tissues of HBF and ABF-fed groups. The HBF and ABF also reduced lipogenesis as induced by depleted fatty acid synthase (FAS) activity in rat adipose tissues. Nevertheless, between the two fats, HBF showed high feed intake due to its high palatability but reduced lipogenic enzyme activity, specifically that of FAS, and increased HDL-C, decreased TC and TG levels in the bloodstream, reduced saturated fatty acids (SFA), and increased oleic and ALA contents in rat adipose tissues indicating that HBF consumption does not pose significant risks of cardiovascular disease.

In this research, the growth efficiency, nutritional utilization, fecal microbial levels, and fecal score of weaned pigs were evaluated using therapeutic zinc oxide (ZnO) and zinc aspartic acid chelate (Zn-Asp). In a 42-day feeding trial, 60 weaned pigs ([Yorkshire × Landrace] × Duroc) were arbitrarily allotted (age: 21 days; 7.01 ± 0.65 kg preliminary body weight) to 3 different treatment groups with 5 repetitions (2 male and 2 female piglets) in each pen. The trial had 2 different phases, including 1-21 days as phase 1, and 22-42 days as phase 2. The nutritional treatments were: basal diet as control (CON), basal diet incorporated with 3,000 ppm ZnO as TRT1, and basal diet incorporated with 750 ppm Zn-Asp as TRT2. In comparison to the CON group, the pigs in the TRT1 and TRT2 groups had greater (p < 0.05) body weight on day 42; an average daily gain, and an average daily feed intake on days 22-42. Furthermore, during days 1-42, the average daily gain in the treatment groups trended higher (p < 0.05) than in the CON group. Additionally, the fecal score decreased (p < 0.05) at week 6, the lactic acid bacteria count tended to increase (p < 0.05), and coliform bacteria presented a trend in reduction (p < 0.05) in the TRT1 and TRT2 groups compared to the CON group. However, there was no difference in nutrient utilization (p > 0.05) among the dietary treatments. Briefly, the therapeutic ZnO and Zn-Asp nutritional approaches could decrease fecal score and coliform bacteria, increase lactic acid bacteria, and improve growth efficiency; moreover, Zn-Asp (750 ppm) can perform a comparable role to therapeutic ZnO (3,000 ppm). So we can use Zn-Asp (750 ppm) instead of therapeutic ZnO (3,000 ppm) for the better performance of weaning pigs and the reduction of environmental pollution, as therapeutic ZnO is responsible for environmental pollution.

This study aimed to investigate the impact of Bacillus subtilis-based probiotics and oregano essential oil on the production performance, egg quality, and intestinal morphology of late-phase laying hens (69-weeks). A total of 150 laying hens of 69-week-old were randomly allotted into 6 treatment groups with 5 replicates of 5 birds in each replicate. Laying hens were divided into high (H) and average (A) egg production groups prior to the trial. The hens in each group were supplemented with Bacillus subtilis, or oregano essential oil: CON, a basal diet; BS, basal diet plus 3 × 10⁸ CFU/kg feed Bacillus subtilis; OEO, basal diet plus 0.3 g/kg feed oregano essential oil. Egg performance, blood characteristics, egg quality, and intestinal morphology of the late-phase laying hens were evaluated. Both BS and OEO significantly enhanced (P<0.05) egg production compared to CON in high egg production. The blood characteristics indicated no significant differences based on the egg production and the supplementation of BS and OEO in the late-phase laying hens. The eggshell strength was significantly improved (P<0.05) in both OEO compared to both CON. A significantly decreased (P<0.05) the villus height to crypt depth ratio (VH/CD) in the ileum compared to H, and in the treatment groups supplemented with BS and OEO, VH/CD showed a significant increase (P<0.05) compared to both CON. These results suggest that the supplementation of Bacillus subtilis and oregano essential oil in the diet of late-phase laying hens could serve as a potential strategy to enhance egg production, egg quality, and gut health.

This study was conducted to evaluate effects of dietary Escherichia coli phytase supplementation on growth performance, carcass quality and excretion of copper and zinc concentrations in finishing pigs. The total of seventy two [(Landrace×Yorkshire)×Duroc] pigs(65.43±0.72 kg in average initial body weight) were used in 56 days assay. Dietary treatments included 1) CON (basal diet) 2) P5(basal diet+phytase 0.05%) and 3) P10 (basal diet + phytase 0.1%). There were three dietary treatments with six replicate pens per treatment and four pigs per pen. During the overall periods, ADFI(Average daily feed intake) was increased (P<0.05) in phytase supplementation treatments compared to CON treatment. At the 5th week, dry matter, nitrogen and ash digestibilities were higher in P5 treatment than in CON and P10 treatments(P<0.05) and CON treatment showed the lowest effect on nutrition digestibility(P<0.05). However, phosphorus digestibility was higher in both phytase supplementation treatments than in CON treatment(P<0.05). The pH of M. logissimus dorsi was significantly higher in CON treatment than phytase supplementation treatments(P<0.05). L* value of M. logissimus dorsi muscle color was significantly increased(P<0.05) in P10 treatment compared to CON and P5 treatments. Also, a* value was increased (P<0.05) in CON treatment compared with phytase supplementation treatments. However, excretion of copper and zinc concentrations were no significant difference among the treatments. In conclusion, the effect of Escherichia coli phytase showed in ADFI, digestibilities, pH and color of meat in finishing pigs.
