This study was carried out to investigate the effects of spider-derived protease [Arazyme (AZ)] supplementation on egg production, egg quality, cecal microflora and viscosity of intestinal contents in laying hens at the late production. A total of two hundred, 59-wks-old, Hy-Line Brown layers were divided into four groups, placed into 5 replicates per group (50 birds per group) and fed one of four diets containing 0.05, 0.075 or 0.1% AZ or control for 5 wks. The results showed that egg weight in group fed the diet containing 0.05% AZ was significantly higher than those of other groups (P<0.05). There were no significant differences in egg interior and eggshell qualities among the groups. The serum parameters such as total cholesterol, the levels of GOT and GPT were not influenced by AZ feeding. There were no significant differences in the cecal number of total microbes, Coliforms and lactic acid bacteria among the groups. The viscosity and ammonia concentration of intestinal contents in the groups fed AZ were significantly reduced compared to those of the control (P<0.05). In conclusion, laying hens fed AZ supplemented diet improved egg weight as compared with that of control. In addition, the AZ supplemented diet reduced the viscosity and ammonia concentration of intestinal contents, reflecting a significant feed enzyme effect.

Seventy two Duroc $\times$ Yorkshire $\times$ Landrace pigs (75.66$\pm$1.86 kg average initial body weight) were used in a 45 days growth assay to determine the effects of Astragalus membranaceus, ginseng and onion complex on growth performance and carcass characteristics of finishing pigs. Dietary treatments included 1) Control (basal diet), 2) AGO 0.25 (basal diet + 0.25% Astragalus membranaceus, ginseng and onion complex), 3) AGO 0.50 (basal diet+0.50% Astragalus membranaceus. ginseng and onion complex). For overall period, average daily weight gain increased as the concentration of Astragalus membranaceus, ginseng and onion complex in the diets was increased (linear effect, p<0.01). Gain/feed improved without significant difference (p>0.05) as the concentration of Astragalus membranaceus, ginseng and onion complex in the diets was increased. As adding level of Astragalus membranaceus, ginseng and onion complex increased in the diets, A grade appearances of carcass tended to increase (linear effect, p<0.01). The total and LDL+VLDL cholesterol concentrations in serum of pigs fed AGO 0.25 diet were lower than them of pigs fed Control and AGO 0.50 diets without significant difference (p>0.05). $L^{*}$-, $a^{*}$-, and $b^{*}$- value of M. longissimus dorsi muscle were not significantly different among the treatments (p>0.05). Total feed cost per kg of weight gain was lower in the AGO 0.50 treatment (813 won) than in the Control (830 won). The results obtained from this feeding trial suggest that the Astragalus membranaceus, ginseng and onion complex supplementation for finishing pigs had improved growth performance. However, carcass characteristic was not affected by supplemental Astragalus membranaceus, ginseng and onion complex.lex.x.

The objectives of this study was to determine the oil contents and fatty acid compositions of soybean germplasms including major Korean cultivars, and to provide the basic information of fatty acid composition for development high quality soybean varieties. Among 46 Korean major cultivated soybean samples, the oil contents were varied from 15.8% to 20.3%, and the average oil content was 18.2%. Crude oil content of cv. Saebyolkong (20.3%) was the highest among that of other cultivated soybeans. Likely many other oils of plant origin, most fatty acids in soybean are unsaturated. The highest percentage of fatty acid in soybean was linoleic acid (18:2), followed in a decreasing order by oleic (C18:1), palmitic (C16:0), linolenic (C18:3), and stearic acid (C18:0). The composition of C18:1 and C18:2 fatty acids among 563 soybean germplasms and cultivars which were positively correlated with nutritional quality of edible vegetable oil, were ranged $13.29{\sim}43.30%\;and\;38.21{\sim}61.51%$, respectively, and the C18:3 which were negatively correlated with flavor quality were varied from 5.03% to 11.48%. Also, the composition of C16:0 and C18:0 which were known to raise total cholesterol levels in human serum were ranged $8.50{\sim}14.78%\;and\;1.86{\sim}4.78%$ respectively. On the other hand, the range of fatty acid composition among 46 Korean major soybean cultivars has been investigated to be: C16:0, $8.96{\sim}13.23%$; C18:0, $2.55{\sim}4.20%$; C18:1, $16.33{\sim}36.41%$; C18:2, $42.32{\sim}58.84%$; C18:3, $6.98{\sim}10.72%$. Among the 563 germplasms tested, there are significant correlations among unsaturated fatty acids: negative between C18:1 and C18:2 (r=-0.961**) or C18:3 (r=-0.756**), and positive between C18:2 and C18:3 (r=0.608**). Also, the C18:1 was negatively correlated with saturated fatty acids, C16:0 (r=-0.231**) and C18:0 (r=-0.479**).

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.

The present study was conducted to compare the carcass yields and meat characteristics of three types of commercial male chicks White mini broilers, Ross broilers and Hy-Line brown chicks under the identical feeding condition. One-hundred 1-d chicks of each type were randomly placed into four pens per group (25 chicks per pen) and fed corn-soybean meal based commercial diets for 35d, 18d or 49d, respectively. At the end of the feeding trial, the birds were sacrificed and subjected to carcass measurements. The dressing percentages of White mini broilers and Ross broilers were significantly higher (P<0.05) than that of Hy-Line brown cockerels. The rate of breast meat of Hy-Line brown cockerels was significantly lower (P<0.05) than those of White mini broilers and Ross broilers. However, Hy-Line brown cockerels showed higher (P<0.05) leg meats than the others. There were no significant differences in serum total cholesterol and the activities of glutamic-oxaloacetic transaminase and glutamic-pyruvic transaminase among the groups. The breast meats of White mini broilers presented highest lightness value. The yellowness of breast and redness of leg meats of White mini broilers and Ross broilers were significantly higher (P<0.05) than those of Hy-Line brown cockerels. There were no significant differences in the SOD-like activity and change of pH in edible meats among the groups. The meat color in White mini broilers was significantly higher than that of Hy-Line brown cockerels. No significant differences were observed in term of flavor, tenderness and overall acceptability. In conclusion, the physico-chemical properties and sensory characteristics of edible meats were not greatly affected by genotype if they were similar body weights and kept under the identical feeding condition. But the Hy-Line brown cockerels were less desirable as a meat-type strain due to lower carcass yields and inferior growth and feed conversion ratio.

In this study, we investigated the anti-obesity activity of Aceriphyllum rossii ethanol extract on rat fed a high fat diet. Male SD rats were divided into four groups. Group 1 was the control. Group 2 was fed a high-fat diet. Group 3 was the positive control, fed a high-fat diet supplemented with Garcinia Cambogia extracts. Group 4 was fed a high fat diet supplemented with ethanol extracts of Aceriphyllum rossii (EEAR). Precisely 166 mg/kg of powdered Garcinia Cambogia extracts was used for Group 3. Also, 250 mg/kg of EEAR was used for Group 4. The Body weight increased Group 2, but decreased Group 4. The serum total cholesterol in Group 2 increased by 15.26% when compared to Group 1, but only increased 5.29% in Group 3 and 4.29% in Group 4. The liver and mesenteric adipose tissue weights of Group 2 increased compared to Group 1, whereas they decreased in Group 3 and Group 4. As a result of measuring the concentration of triglycerides in extracted livers, Group 2 showed a significant increase compared to the Group 1, and Groups 3 and 4 showed significant decrease compared Group 2. These results suggest that Aceriphyllum rossii ethanol extracts may be useful as an anti-obesity agent.

This study was conducted to investigate the effects of dietary Animunin Powder$^{?}$ on the egg quality characteristics, blood components and nutrient digestibility in laying hens. A total of two hundred seventy laying hens were randomly allocated into three treaments with fifteen replications for eight weeks. Dietary treaments included 1) Control (CON), 2) Control + $0.1\%$ Animunin Powder$^{?}$ (AM1), 3) Control + $0.2\%$ Animunin Powder$^{?}$ (AM2). During the period of 0~4weeks, the birds fed the AM1 diet had an improved egg production compared to the birds fed the CON (P<0.05). During the period of 4~8weeks the birds fed AM1 diet showed a statistically improved egg production compared to the CON (P<0.05). However, no significant differences were founded in the egg weight. During the period of $4\~8$ weeks the hens fed the AM2 diet had improved egg yolk color compared to the hens fed CON and AM1 diets (P<0.05). In the Haugh unit for the period of $0~4$$weeks, the AM2 treatment showed significantly improved results compared to the CON (P<0.05). Average egg shell breaking showed no significant differences through the experiment period, but in the period of $4\~8$weeks the AM2 treatment tended to be improved compared to the CON and AM1 treatment (P<0.05). There was no significant differences in egg shell thickness. In the serum cholesterol, the AM1 and AM2 treatments were significantly lower than the CON (P<0.05). The concentration of RBC and WBC in the AM treatments tended to increase but there were no significant differences. For the differences of lymphocytes between the end and initiation of the experiment, the hens fed the AM1 treatment were significantly different compared to the hens fed the CON and AM2 treatment (P<0.05). During the period of the experiment, the hens fed the AM1 diet were tended to show higher DM digestibility than the hens fed the CON and AM2 diet, but it was not statistically different. In conclusion, dieatry fed of Animunin Powder$^{?}$ could improve egg production, egg yolk color, and haugh unit.

Purpose : The objective of this study was to evaluate the effects and adverse side-effects of growth hormone (GH) therapy in children with Prader-Willi syndrome (PWS). Methods : Forty-one patients who had been treated with GH for more than two years (24 boys and 17 girls, mean age $7.3{\pm}3.3$ years during treatment initiation) were enrolled for this study. Results : After 2 years of GH therapy, the height and weight standard deviation scores (SDS) increased significantly ($-1.19{\pm}1.37$ vs. $-0.02{\pm}1.45$, and $1.02{\pm}2.42$ vs. $1.63{\pm}2.22$, P<0.002); however the percentage body fat decreased ($44.6{\pm}9.9%$ vs. $38.1{\pm}10.5%$, P<0.001). Further, no change was observed in the thyroid and serum glucose levels, but the total cholesterol level decreased. GH therapy did not impact glucose control in the patients with diabetes. The most common adverse effects of GH therapy were the progression of scoliosis and adenoid hypertrophy. Conclusion : GH therapy improved the height SDS and body composition in patients with PWS. However, GH should be used with caution in patients with scoliosis and adenoid hypertrophy.

Purpose: Thin glomerular basement membrane nephropathy (TGBMN) is recognized as the leading cause of microscopic hematuria in both children and adults. However thinning of glomerular basement membrane (TCBM) has been found in healthy adult and also is known to be associated with various renal diseases such as Alport syndronh, IgA nephropathy and mesangial proliferative glomerulonephritis. The association of TGBM with minimal change nephrotic syndrome (MCNS) has been very rare so that the present study was undertaken to determine the relationship between TGBM and MCNS. Methods: The study population consisted of 49 children with biopsy- proven MCNS who have been admitted to the pediatric department of Kyungpook University Hospital during the past 5 years from 1997 to 2001. Group I consisted of 8 children associated with TGBM and Group II 41 children without TCBM. Various parameters such as age of illness, duration from discovery of illness to the time of biopsy, family history of hematuria and other laboratory tests were compared between these two groups and the following results were obtained. Results: Age distribution showed slightly older age in Group I ($7.1{\pm}3.5$ years) compared to Group II ($4.8{\pm}2.9$ years). However this was not statistically different (P=0.056). Family history of hematuria was noted in 2 cases in Group II. Though statistically not significant, hematuria was seen in 2 out of 8 cases ($25\%$) in MCNS children with TGBM, compared to 7 out of 41 cases ($17\%$) with MCNS children without TGBM. Other parameters such as BUN, creatinine, 24 hours urine protein excretion, serum protein, albumin, cholesterol, and T4/T8 ratio, showed no difference. Also renal biopsy finding showed no significant difference and the thickness of glomerular basement membrane in Croup I was $188{\pm}30nm$. Conclusion: TGBM was found in 8 out of 49 children with MCNS ($16.3\%$). And this high frequency of occurrence indicates that these association is not an incidental findings. Typical clinical findings of TCBMN was not noted in all of the 8 children with MCNS associated with TGBM, suggesting that thinning of glomerular basement membrane (TCBN) is secondary to rather than the cause of MCNS.
