The nutritional properties of the Chol-Pyon were investigated with changing the materials (mugwort and pine leaves). In proximate composition, rice powder added mugwort and pine leaves showed the lligher con-tents of crude protein, crude lipid and crude ash than in rice powder. Ihe pH of rice powder, mugwort and pine leaves was 6.4, 6.8 and 3.5, respectively. The rice powder added pine leaves showed the lowest pH value. The content of the free sugar in raw materials for ChOl-PyOn preparation was 0.9% in rice powder, 0.3% in mugwort and 2.7％ in pine leaves. Eighteen kinds of amino acids were determined in raw materials for ChOl-fyOn preparation and their contents were 4.8% in mugwort, 4.2% in rice powder and 2.8% in pine leaves. The major minerals of raw materials for ChOl-PyOn preparation was 0.9％ increased in the order of K> Na > Mg > Ca in rice powder, Mg > K > Ca > Na in mugwort, and K > Ca > Mg > Na in pine leaves. Both of mugwort and pine leaves additives showed the higher contents of 8 kinds of minerals (Ca, Mg, K, Na, Mn, Fe, Cu, Zn) than in rice powder. In relation to changes in the texture of ChOl-PyOn, hardness, fracturability and adhesiveness at 25${\pm}$1$^{\circ}C$ were measured to be highest in white ChOl-PyOn. Cohesiveness was shown to be highest at 15％ in case of mugwort and 2.5％ in case of pine leaves. Elasticity was measured to be highest at 0.99 in case that 7.5% mugwort was added to raw materials for ChOl-PyOn. As a result of estimating the sensory qualities of the ChOl-PyOn prepared to which the additives were added in differing amounts, immediately after its preparation the mugwort additive of 7.5％ showed the superior sensory qualities Chol-PyOn (p < 0,01).

The chemical components of Citrus junos produced in Korea were divided into two parts; common and special components respectively. In the former the relation between the physiological effects of the plant and its ripening process was observed periodically while the latter was analyzed the ripening fruits for their effective utilization as food. The results are summarized as follows: 1. The analytical result of seasonal change showed that the rind ratio was higher than the flesh ratio and on a regional basis, the rind ratio was higher in the islands than on land areas. 2. In the experiment the moisture was increased until the third period, but afterwards it was made constant. While the content of crude fat, cellulose, ash, total acid and soluble non-nitrogen material were decreased until the third period and the cotent of cellulose and total acid were continuousely redused until the last period. In con trast with the above the content of reducing sugars was increased but the content of crude fat, cellulose, ash, crude protein and soluble non-nitrogen material were increased until last period. 3. The content of vitamin C was richer in the rind than in the flesh, in the Korean species than in the Japanese. 4. Free sugars; xylose, fructose, glucose were richer in the rind than in the flesh. 5. The content of volatile organic acids was richer in the rind than in the flesh. Among them, volatile acids, acetic acid, formic and n-valeric acid were found in the rind and formic acid, acetic acid and propionic acid were deteceed in the flesh. 6. The total content of non-volatile acids was richer in the flesh than in the rind. In the kind of non-volatile acids, citric acid,glutaric acid, malic acid, tartaric acid, oxalic acid, malonic acid, succinic acid and an unknown acid were found in the rind and citric acid, malic acid, succinic acid, oxalic acid, glutaric acid and malonic acid in the flesh. 7. Three kinds of aromatic components: D-limonene, ${\alpha}-pinene$, p-cymene and seven other kinds of unknown aromatic components were detected in neutral essential oils. Among them, D-limonene seemed to be main aromatic component in the fruits. 8. From the above results it is confirmed that both rind and flesh of the ripened fruit could be utilized for food effectively, and unripened fruits are suitable for producing citric acid, ripened fruits are also useful for producing juice.

Traditionally, patients with stage IIIB non small cell lung cancer (NSCLC) have been con-sidered Inoperable due to the short-term survival rate of this disease. However, some recent papers have reported good surgical treatment results for T4 lesions in stage IIIB NSCLC. This study reports the results of stage IIIB NSCLC patients who underwent surgical treatment at our institute. Material and Method: This study includes 109 patients who were diagnosed with pathological stage IIIA lung cancer and 59 patients who were diagnosed with pathological stage IIIB at our institute between 1994 to December 2001. Patients who underwent neo-adjuvant chemotherapy and radiation therapy were excluded from this study. According to the TNM classification, 13 patients from stage IIIA were classified into T3N1, 12 into T1N2, 73 into T2N2 and 11 into T3N2. Stage IIIB patients consisted of 26 patients with T4N0, 18 with T4Nl, 14 with T4N2, and 1 with T4N3. Result: The 30-day mortality for stage IIIA and IIIB were 4.58% and 5.08% respectively. The overall survival rate at the 1st, 2nd, 3rd, and 5th year were 69.1%, 53.7%, 41.6%, and 30.7% respectively in stage IIIA and 68.8%, 55.6%, 42.9%, and 35.9% respectively in stage IIIB. Patients with satellite nodules in the same lobe & no Iymph node involvement had a survival rate of 53.9% in 3 years compared with 15.2% in patients with satellite nodules in the same lobe with Iymph node involvement. Conclusion: Surgical treatment is recommended for selected stage IIIB NSCLC patients (pathological N0 stage & completely resectable patients), particularly for patients with satellite nodules in the same lobe & no lymph node involvement.

We evaluated the efficacy of Dor procedure in patients with ischemic left ventricular dysfunction. Material and Method: Between April 1998 and December 2002, 45 patients underwent the Dor procedure con-comitant with coronary artery bypass grafting (CABG). Left ventricular ejection fraction (LVEF) and left ventricular end-diastolic/end-systolic volumes (LVEDV/LVESV) were measured by echocardiography, myocardial SPECT, and cardiac catheterization and angiography performed at the sequence of preoperative, early postoperative, and one year postoperative stage. Result: Cardiopulmonary bypass and aortic clamp times were mean 141$\pm$64, 69$\pm$24 minutes, respectively. Intraaortic balloon pump (IABP) therapy was required in 19 patients (42%; 7 preoperatively, 9 intraoperatively, 3 postoperatively). Operative mortality rate was 2.2% (1/45). Postoperative morbidities were low cardiac output syndrome (12), atrial fibrillation (5), acute renal failure (4), and postoperative bleeding (4). Functional class (NYHA) was improved from classes 2.8 to 1.1 (p < 0,01). When we compared between the preoperative and early postoperative values, LVEF was improved from 32$\pm$9% to 52$\pm$11% (p<0.01). The asynergy portion decreased from 57$\pm$12% to 22$\pm$9%, and LVEDV/LVESV indexes improved from 125$\pm$39 mL/$m^2$, 85$\pm$30 mL/$m^2$ to 66$\pm$23 mL/$m^2$, 32$\pm$16 mL/$m^2$ (p<0.01). Although these changes in volumes were relatively preserved at postoperative one year, the left ventricular volumes showed a tendency to increase. Conclusion: After the Dor procedure for ischemic left ventricular dysfunction, LVEF improvement and left ventricular volume reduction were maintained till postoperative one year. The tendency for left ventricular volume to increase at postoperative one year suggested the requirement of strict medical management.

Current study was conducted to investigate the effect of organic selenium supplementation originated from mushroom culture medium on meat quality of Hanwoo sleets. The result showed that organic selenium supplementation of 0.9 ppm (DM based ratio) for 2 (T1), 4 (T2) and 6 (T3) months had no effect on moisture content in longissimus muscle, with 63 to $66\%$ compared to non-supplemented control group Similarly, intramuscular fat content ranged from 11.7 to $16.4\%$ did not differ between the treatment groups (p>0.05). T3 group showed the highest protein content with $20.8\%$ while T2 group had the lowest content with $19.2\%$ The data indicated that organic selenium supplementation to the experimental concentration had indictable effect on proximate composition The treatments similarly had no influence on physical and biological characteristics of longissimus muscle, where cooking loss and shear force ranged from 20 to $21\%$ and from 3.6 to 4.4kg, respectively. On the other hand, muscle pH at 24 h postmortem showed 5.52, 5.57, 5.50, 5.50 for control, T1, T2 and T3, respectively, indicating that the longer feeding period resulted in the lower ultimate un A similar trend was observed from water-holding capacity (63.8, 64.4 and $64.2\%$ for T1, T2 and T3, respectively) which was significantly higher than con01 group of $59.5\%$ For sensory evaluation, juiciness did not differ between the treatment groups, but n and n (5.30 and 5.28, respectively) showed significantly tender mat Particularly, T2 group received significantly higher flavor score among the treatment groups including controls. The data indicated that organic selenium supplementation to the experimental concentration had no effect on beef quality, but the treatment effect on anti-oxidation function is remained for further studies.

Changes in lipid components of Gul-bi, salted-dried yellow corvenia, during processing and storage were studied. Raw fishes contained $6.7\%$ total lipid (TL) which consisted of $83.3\%$ neutral lipid (NL), $6.5\%$ glycolipid (GL) and $10.2\%$ phospholipid (PL), and salted-dried sample at 30 days storage contained $11.1\%$ TL which consisted of $86.1\% NL, $7.1\%$ GL and $6.8\%$ PL. The NL was mainly consisted of trigly ceride (TG), free sterol (FS), free fatty acid (FFA), and the main lipids in PL were phosphatidyl choline (PC), phosphatidly ethanolamine (PE) and sphingomyelin (SPM). The contents of TG, PC, PE decreased, while that of FFA, SPM increased during processing and storage. Total fatty acid contents of raw fish, salted sample, salted-dried sample (product) and product at 30/days of storage were 847.9, 764.0, 633.5 and 588.mg/g-lipid, respectively, taking $C_{23:0}$ as the internal standard material. Most fatty acid con tents of TL revealed a tendency to decrease during processing and storage, highly unsaturated fatty acid such as $C_{22:6},\;C_{20:5}$, decreased largely. The major fatty acids in TL, NL, GL and PL were generally $C_{16:0},\;C_{16:1},\;C_{18:1},\;C_{20:5},\;C_{22:6}. Percentage of $C_{16:1},\;C_{18:1}$ in NL and GL and GL are higher than those in PL, while $C_{22:6},\;C_{20:5},\;C_{20:4}$. Peroxide value in salted-dried sample is 121.6 meq/kg and decreased rapidly with storage period, carbonyl value and brown pigment formation showed tendency of increase during processing and storage.

We investigated whether 1) the combined capsaicin (75 mg), sesamin (30 mg), and L-carnitine (900 mg) (CCSC) ingestion enhances autonomic nervous system (ANS) activities including thermogenic sympathetic activity as energy metabolic modulator, 2) ${\beta}_3-AR$ polymorphism of each subject influences with ANS activity. Seven healthy males $(22.0{\pm}0.5\;yr)$ volunteered for this study. The cardiac autonomic nervous activities evaluated by means of heart rate variability of power spectral analysis were continuously measured during 5 min every 30 min for total 120 min resting condition with CCSC or placebo oral administration chosen at random. The results indicated that, there are not $Arp/Arg^{64}$ variants of the ${\beta}_3-AR$ genotypes in our subjects. There were not also significant differences in heart rate during rest between both trials. The difference of ANS activity did not reach the statistical significance between both trials. However, the significant improvement showed TOTAL power, HF component, and the indices of SNS and PNS activities before and at 30 min after CCSC ingestion (p<0.05, respectively). In conclusions, although each component of combined CCSC is associated with lipolysis and/or fat oxidation, the combined CCSC consumption is not influenced in stimulation of thermogenic sympathetic activity as modulator of energy metabolism. In rather, our results suggested that CCSC ingestion improves the balance of both SNS and PNS activities. Therefore, it will be considered many combined nutrient components for ergogenic and/or lipolysis effects as well as genetic variants affecting ANS activity in further studies.

This study was conducted to investigate the effects of feeding probiotics(gene modified yeast) on the egg quality in laying hens. The laboratory method of this study is as follow: In hens, 300, 36 weeks old ISA brown commercial layer, were employed in 13weeks feeding trial with a 7 days adjustment period. Dietary treatments are 1) control (basal diet) 2) Y0.3 (basal diet+0.3% probiotics), 3) Y0.5% (basal diet+0.5% probiotics), 4) PY0.3% (basal diet+0.3% plasmid modified probiotics), 5) PY0.5% (basal diet+0.5% plasmid modified probiotics). For overall period, hen-day egg production, egg weight (p<0.05) by dietary probiotic supplementation were recorded. Eggs were collected and weighed every day. Egg production number and egg production rate, egg weight, failure egg ratio and trouble egg ratio were recorded for 13weeks days. Diets PY0.3 and PY0.5 improved Egg production rate, egg production number and egg weight, compared to control diet (linear effect. p<0.05). And, diets PY0.3 and PY0.5 improved Egg production rate, egg production number, compared to Y0.3 and Y0.5 (linear effect. p<0.05). But, in Inferior egg and cracked egg, diets PY0.3 and PY0.5 did not tended to increase by dietary probiotic supplementation compared to control diet and Y group (0.3, 0.5) (linear effect. p<0.05). The productivity enhance on the egg quality in laying hens is considered from the effects of feeding probiotics(gene modified yeast).

The present study aimed to investigate the effects of lycopene on hepatic metabolic- and immune-related gene expression in laying hens. A total of 48 25-week-old White Leghorn hens were randomly allocated into four groups consisting of four replicates of three birds: control (basal diet), T1 (basal diet + 10 mg/kg of tomato powder-containing lycopene), T2 (basal diet + 10 mg/kg of micelles of tomato powder-containing lycopene), and T3 (basal diet + 10 mg/kg of purified lycopene). Chickens were fed ad libitum for 5 weeks, and then total RNA was extracted from the livers for quantitative RT-PCR analysis. Peroxisome proliferator-activated receptor ${\gamma}$ (PPAR${\gamma}$) expression was decreased in the liver of chickens after lycopene supplementation (P<0.05). Micellar lycopene supplementation decreased the expression of PPAR${\gamma}$ target genes including fatty acid binding protein 4 (FABP4) and fatty acids synthase (FASN) in the T2 group (P<0.05). Sterol regulatory element-binding protein 2 (SREBP2) and C/EBP-${\alpha}$ were also downregulated in hens fed with micellar lycopene (P<0.05). Glucose transporter 8 (GLUT-8) was upregulated in the T2 and T3 groups (P<0.05). However, the expression of carnitine palmitoyltransferase 1 (CPT-1) was not changed by lycopene supplementation. Pro-inflammatory cytokines such as tumor necrosis factor ${\alpha}$ (TNF-${\alpha}$) and interleukin 6 (IL-6) were downregulated by lycopene supplementation (P<0.05). These data suggest that the type of lycopene supplementation is critical and that micelles of tomato powder-containing lycopene may play an important role in the modulation of lipid metabolism and immunity in chickens.
