Two experiments were conducted to evaluate the feeding values of red pepper seed oil meal (RPSOM) and to investigate its dietary supplementation on broiler performances. In Exp. 1, nutritional values of RPSOM were evaluated by analyzing chemical composition and determining true metabolizable energy (TME), nitrogen corrected TME (TMEn) and true available amino acid (TAAA). RPSOM contained 22.50% of CP, 4.75% of ether extract, 27.70% of crude fiber, 4.73% of crude ash and 49.97 ppm of xanthophylls. The contents of capsaicin and dihydrocapsaicin were 34 mg and 31 mg/100 g DM, respectively. The values of TME and TMEn determined by force-feeding 16 roosters were 1.73 kcal/g and 1.63 kcal/g DM, respectively. The average TAAA value of 17 amino acids was 85.22%. In Exp. 2, a total of 225 Ross male broiler chicks, 3 weeks old, were randomly divided into 9 groups of 25 birds each and assigned to three experimental diets containing 0 (control), 5 or 10% RPSOM fed ad libitum for 3 weeks. No significant differences were observed in growth performances and carcass characteristics. The level of serum cholesterol in the 10% RPSOM group was significantly lower than that of the control group (113.92 vs. 137.50 mg/dl). The dietary RPSOM at 5 and 10% levels increased the content of C18:2 ${\omega}{\sigma}$ in leg muscle compared with the control group. The results suggested that RPSOM can be included into broiler feed up to 10% without any negative effects on broiler performances and physiological responses and used as a non-conventional plant protein source, if its nutritional values are well evaluated.

These experiments were conducted to evaluate the nutritional and feeding value of red pepper seed oil meal (RPSOM) as local vegetable protein ingredients for poultry feeding. In the first experiment, nutritional values of RPSOM were evaluated by analyzing chemical compositions and determining true metabolizable energy (TME), nitrogen corrected TME (TMEn) and true available amino acid (TAAA) contents. According to the chemical analysis, RPSOM contained 22.50％ of crude protein, 4.75％ of ether extract, 27.70％ of crude fiber, 0.34 mg／g of capsaicin and 49.97 ppm of xanthophylls. The values of TME and TMEn determined by force-feeding 16 roosters (ISA-Brown) were 1.73 kcal／g and 1.63 kcal／g on dry matter basis, respectively. The average TAAA value of 16 amino acids measured by the force－feeding technique was 81.70％. These values were used for formulating experimental diets containing various levels of RPSOM for broiler chicks and laying hens. Two feeding trials were made to investigate the effects of dietary incorporation of RPSOM into chicken feed performances of broiler chicks and laying hens. In the broiler feeding (Exp. 2), a total of two hundred twenty-five, 4 wk old male broiler chicks (Ross) were randomly divided into 9 groups of 25 birds each and assigned to three experimental diets containing 0, 5 and 10% RPSOM. The birds were fed ad libitum the diets for 3 wk and feed intake, weight gain and feed conversion rate were determined. At the end of the feeding, the blood levels of glutamate oxaloacetate transaminase (GOT), gamma glutamyl transpeptidase (GGT), blood urea nitrogen (BUN) and cholesterol, and the body and fatty acid compositions of leg muscle were measured. No significant differences were observed in weight gain, feed intake, feed conversion rate, body composition, serum levels of GOT, GGT and BUN among the treatments. However, blood cholesterol level was lower (P＜0.05) in 10% RPSOM diet group than those in the other. The dietary RPSOM at 5 and 10% levels increased the content of linoleic acid (P＜0.05) in leg muscle compared to that of control group. The results indicate that RPSOM can be used for broiler feed up to 10% without any significant negative effects on broiler performance. In the layer feeding (Exp. 3), the effects of dietary RPSOM on the performances of laying hen were investigated by feeding ninety 45 wk old laying hens (ISA-Brown) with experimental diets containing 0, 5 and 10% RPSOM for 4 wk (30 birds per treatment). Measurements were made on egg production rate, egg weight, feed intake, Haugh unit, egg shell strength which was higher (P＜0.05) in layers fed 10% RPSOM diet compared to those fed 0 and 5% RPSOM diets. Thus, it can be concluded that RPSOM can be included into laying hen feed up to 10% without any harmful effects.

This study was carried out to investigate the nutritional value of soybean meal (SBM) from various geographic origins and the effects of their dietary supplementation on performance of broiler chickens. Nutritional value of dehulled SBM originating from USA, and non-dehulled SBM from India (IND), Argentina (ARG) and Korea (KOR) were evaluated by analyzing chemical composition, urease activity (UA) and KOH solubility, and determining true metabolizable energy (TME), nitrogen corrected TME (TMEn) and true amino acid availability (TAAA). The contents of crude protein ranged from 45.43% (ARG) to 48.47% (USA) and those of crude fiber varied widely from 3.48% (USA) to 7.12% (IND). The measurements of lysine varied from 2.79% (IND) to 3.09% (USA) and those of methionine from 0.56% (IND) to 0.65% (USA). The values of TMEn varied from 2986.6 kcal/kg (IND) to 3228.9 kcal/kg (USA) and the averages of TAAA were from 91.61% (IND) to 92.27% (USA). UA was found to be from 0.02 (ARG) to 0.04 (KOR, USA) and those of KOH solubility from 73% (ARG) to 84% (USA). A total of four hundred 20-days-old male broiler chicks were divided into four groups and fed with isocaloric and isonitrogenous experimental diets containing 27.5% of SBM and same amounts of lysine and sulfur amino acids for 15 days. Final body weight and body weight gain were the highest in birds fed with SBM from USA and lowest in birds fed with SBM from IND although the differences were not statistically significant. The feed/gain in chicks fed diet containing SBM from USA was significantly improved (p<0.05) compared to those of the other groups. There were no significant differences in carcass characteristics and the concentration of total cholesterol in serum among the treatments. The results of in vitro assay and bioassay agreed with the performance of broiler chicks, and thus there were close correlation between the broiler performance and the measured nutritive values of SBM. In conclusion, dehulled SBM from USA was superior to non- dehulled SBM from ARG and IND with regard to nutritive values.

This study was conducted by dividing L-arginine intake group (n=14) and placebo group (n=14) to investigate the effect of L-arginine intake on athletic performance, lactate, lactate dehydrogenase, and ammonia of men's college Taekwondo Kyorugi players during 8-week of intensive winter training. The L-arginine intake group consumed a total of 3 g, including 1 g for breakfast, 1 g for lunch, and 1 g for dinner, and the placebo group consumed maltodextrin in the same way. The 8-week winter training program was conducted at 70-90%HRR (heart rate reserve). Two-way repeated measures ANOVA was used for the interaction between the L-arginine intake group and the placebo group of the measured data, paired t-test was used for the difference between the periods within the group, and the difference between groups was analyzed using independent t-test. As a result, there was an interaction between groups in the average number of kicks among the performance ability through the TAAA (Taekwondo-specific aerobic anaerobic agility) test , and the main effect between groups was shown (p<.05). In addition, there was an interaction between groups and time in the kick fatigue index (p<.05). In lactate, the time-interaction were shown (p<.05) and interaction effects and inter-time main effects were observed in lactate dehydrogenase (LDH)(p<.05). In the case of ammonia, the interaction effect between the group and time was shown (p<.05). These results show that L-arginine intake can play a positive role in quickly synthesizing nitric oxide in blood vessels and expanding blood vessels to quickly remove fatigue-causing substances in the body for athletes who are easily exposed to fatigue after high-intensity training for male college Taekwondo Kyorugi players. Therefore, it is recommended to take L-arginine as a way to improve the performance of high-intensity elite Taekwondo Kyorugi players and recover from fatigue.

Between 1987 and 1994, 21 patients were treated surgically for aortic aneurysm involving the thoracoabdominal aorta. There were 11 males and 10 females, and their age ranged from 20 to 67 years old and mean age was 41.5 years. Many complained of back pain, chest pain or discomfort, and flank pain, but three patients were asymptomatic. 15 patients had chronic dissection (71.4%) and 6 had nondissecting fusiform or saccular aneurysm(28.5%), and of those 15 patients with chronic dissection, 6(28.5%) had atherosclerosis assniated with hypertension, 5 (23.8%) were Martian syndrome, and 2 (9.5%) were associated with pregnancy. The diameter of an aneurysm ranged from 6cm to 12cm, and their extent was classified as type I in 7(33.3%), type II in 8(38.1%), type III in 3(14.3%), and type IV in 3(14.3%) patients based on Crawford classification for TAA . Diseased aorta was replaced with artificial vascular graft in all but one patient. In whom the aortic tear site due to pseudoaneurysm was closed by primary suture. For the spinal cord protection during the operation, we used partial cardiopulmonary bypass (FV-FA or PA-FA bypass) in 12 patients (57.1%), Biopump (LA-FA bypass) in 4(19.0%), total circulartory arrest and CPB in 2 (9.5%), Gott's heparinized shunt in 1(4.7%), and simple aortic cross clamping in 2 (9.5%). The most common complication after the operation was hoarseness due to unilateral vocal cord palsy which onured in 5 patients (23.8%), and the next common complication was wound infection in 4 patients(19.0%), paraplegia in 2 patients (9.5%), chylothorax in 1 patient(4.7%). The hospital mortality rate was 9.5% (2deaths), and there was no late death. Our experience shows that the graft replacement of TAAA had reasonable rate of mortality, low rate of serious complication, and provided good post operative state of the pati nts, and since the thoracoabdominal aortic operation is not a high risky procedure anymore, we recommend a radical operation for the indicated patients.
