본 연구는 selenium binding yeast peptide의 식이내 첨가가 돼지의 생산성, 조직내 Se, 혈청내 GSH-Px의 활성 및 돈육의 품질에 미치는 영향을 확인하고자 실시하였다. 3원 교잡종(Duroc×Yorkshire×Landrace) 비육돈 80두를 공시하였으며 시험개시 시의 체중은 82.88±1.23 kg이었다. 시험설계는 옥수수-대두박 위주의 식이로서 처리한 대조구(CON: 기초식이), 대조구 식이 내 selenium binding yeast peptide 물질을 0.05%(SY1: 대조구+0.05% selenium binding yeast peptide), 0.1%(SY2: 대조구+0.1% selenium binding yeast peptide) 및 0.2% 첨가한 구(SY3: 대조구+0.2% selenium binding yeast peptide)로 4개 처리를 하여 처리 당 5반복, 반복 당 4두씩 임의 배치하였다. 사양기간 동안의 성장률에서는 selenium binding yeast peptide를 급여한 처리구가 대조구에 비하여 다소 높은 경향을 보였지만, 유의적인 차이는 보이지 않았다(p>0.05). 명도를 나타내는 L^*-값은 SY2가 대조구와 SY1에 비하여 유의적인 차이를 보였다(p<0.05). 적색도를 나타내는 a^*-값은 대조구가 다른 처리구와 비교하여 낮은 수치를 나타내었다(p<0.05). 혈청 내 Se의 함량은 대조구가 516 mg/mL로 selenium binding yeast peptide를 급여한 처리구에 비하여 낮게 나타났지만 유의적인 차이는 보이지 않았다(p>0.05). 등심의 Se 함량은 대조구(0.008 ㎍/g)에 비해 SY2(0.021 ㎍/g) 및 SY3(0.031 ㎍/g)에서 유의적인 차이를 나타냈다(p<0.05). 신장의 Se함량에서는 SY2와 SY3가 대조구 및 SY1과 비교하여 유의적으로 높게 나타났다(p<0.05). 간에서는 SY1이 대조구에 비하여 높게 나타났다(p<0.05). 위의 결과를 종합하여 볼 때 비육돈 식이내 selenium binding yeast peptide의 첨가는 등심, 신장 및 간에서 많이 축적되는것으로 보이며, 육색에도 영향을 미치는 것으로 보인다. This study was conducted to evaluate the effects of selenium binding yeast peptide supplementation on growth performance, tissue Se, serum glutathione peroxidase activity and meat quality in finishing pigs. A total of eighty (Duroc×Yorkshir×Landrace) pigs (82.88±1.23 kg average initial body weight) were used in a 35-day assay. Dietary treatments included 1) CON (basal diet), 2) SY1 (CON diet+0.05% selenium binding yeast peptide), 3) SY2 (CON diet+0.1% selenium binding yeast peptide) and 4) SY3 (CON diet+0.2% selenium binding yeast peptide). Overall period, average daily gain of pigs fed selenium binding yeast peptide diet was higher than that of pigs fed CON diet, however, there was not significant difference (p>0.05). L^* (lightness) value of M. longissimus dorsi was higher in SY2 than CON and SY3 (p<0.05). a^* (redness) value of M. longissimus dorsi was lower in CON than other treatments (p<0.05). Selenium content in serum was increased as adding selenium binding yeast peptide compared to pigs fed CON diet. However, there was not significantly different among the treatments (p>0.05). Selenium content of M. longissimus dorsi was higher in SY2 (0.021 ㎍/g) and SY3 (0.031 ㎍/g) than CON diet (0.008 ㎍/g) (p<0.05). Selenium content of kidney was increased in SY2 and SY3 compared to pigs fed CON and SY1 (p<0.05). Selenium content of liver was higher in SY1 than CON (p<0.05). In conclusion, it is suggested that selenium content could be accumulated in M. longissimus dorsi, kidney and liver by selenium binding yeast peptide supplementation, and meat color of M. longissimus dorsi could be affected by selenium binding yeast peptide supplementation.

의약용 당단백질에 부가된 당사슬의 중요성

김성훈,권오석,오두병,Kim, Seong-Hun,Kwon, Oh-Suk,Oh, Doo-Byoung 한국식물생명공학회 2010 식물생명공학회지 Vol.37 No.3

High value-added therapeutic proteins have been leading the biologics industry and occupied major portion of the market. More than 60% of the currently available protein therapeutics are glycoproteins attached with glycans which play crucial roles for the protein folding, therapeutic efficacy, in vivo half-life and immunogenecity. This review introduces the process of glycosylation and the impacts of glycans in the aspects of therapeutics. The important glycan structures in therapeutic performances were also summarized focusing on three representative categories of glycoproteins, cytokines, therapeutic antibody and enzyme. Currently, mammalian expression systems such as Chinese hamster ovary cells are preferred for the production of therapeutic glycoproteins due to their ability to synthesize glycans having similar structures with human type glycans. However, recent advances of plant glycoengineering to overcome the limitation originating from different glycan structures will soon allow to develop more efficient and economic plant-based production systems for therapeutic glycoproteins.

본 연구는 비육돈 사철내 산조인의 첨가가 성장, 혈액 내 cortisol 및 육질에 미치는 효과를 알아보고자 실시하였다. 3원 교잡종(Duroc${\times}$Yorkshir${\times}$Landrace) 비육돈 36두를 공시하였으며 시험개시시의 체중은 $91{\pm}2.11$ kg이었다. 시험설계는 옥수수-대두박 위주의 사료를 30일동안 급여한 처리구(CON:대조구), 대조구 사료를 15일 급여후 산조인 0.1% 첨가한 사료를 15일 급여한 처리구(T1), 대조구 사료내 산조인 0.1%를 첨가하여 30일간 급여한 처리구(T2)로 3개 처리를 하여 처리당 3반복 반복당 4두씩 임의 배치하였다. 증체량, 사료섭취량 및 사료효율은 전 시험기간에서 처리구간의 통계적인 차이를 보이지는 않았으나, 대조구에 비해 산조인을 첨가한 처리구가 사료섭취량은 감소하면서 사료효율은 증가하는(p<0.05)경향을 보였다. 등지방 두께는 대조구에 비해 T1처리구가 유의적으로 얇게 나타났다(p<0.05). 처리구별 A등급과 B등급의 출현율은 CON이 58%, T1은 74%, 그리고 T2는 84%를 보였다. 등심의 L/sup */값은 대조구가 다른 처리구들에 비해 높게 나타났지만(p<0.05) 저장 7일후 처 리구 모두 증가하는 경향을 보였고 T2 처리구가 다른 처리구들에 비해 높게 나타났다 (p<0.05). 또한 적색도를 나타내는 a/sup */값과 황색도를 나타내는 b/sup */값에서 처리구간의 유의적인 차이는 없었다. 혈액 내 cortisol의 수준은 처리구간의 유의적인 차이는 보이지 않았으나 T2 처리구가 낮은 경향을 보였다. 마블링, 단단함 및 육색의 NPPC에 의한 결과에서는 처리구간의 유의적인 차이는 보이지 않았다. 이상의 결과를 종합하여 볼 때, 사료내 산조인의 첨가는 육질에 영향을 미칠 수 있을 것으로 보이나, 기능성 돈육으로서의 비육돈 자체의 생리활성이나 돈육의 지방산 조성등 육질 평가에 대한 더 많은 연구가 필요하리라 여겨진다. This study was conducted to evaluate the effects of Zizyphus vulgaris supplementation on growth performance, blood cortisol and meat quality characteristics in finishing pigs. The total of thirty-six [Duroc${\times}$Yorkshir${\times}$Landrace] pigs ($91{\pm}2.11$ kg average initial body weight) were used in a 30-days assay. Dietary treatments included 1) CON (basal diet), 2) T1 (basal diet for 15 days and 0.1 % Zizyphus vulgaris for 15 days) and 3) T2 (0.1 % Zizyphus vulgaris for 30 days). The ADG (Average daily gain), ADFI (Average daily feed intake) and ADG/ADFI during the feeding period were not significantly differences among the treatments (p>0.05). Backfat thickness of pigs fed CON was higher than those of T1 and T2 (p<0.05). The appearance rate of A or B carcass grade was in T1 (74%) and T2 (84%) was significantly higher than that in CON (58%) (p<0.05). Pigs fed Zizyphus vulgaris 0.1 % for 30 days tended to decrease on blood cortisol compared with pigs fed CON and T1. But, there was not significantly difference among the treatments (p>0.05). The Hunter's L/sup */ (lightness) value of loin in the pork fed CON was higher than that of loin in the pork fed T1 and T2 (p<0.05). After 7 days, the L/sup */ value of loin in the pigs fed T2 was higher increased than that of pigs fed T1 and CON (p<0.05). However, a/sup */ and b/sup */ values were not affected by dietary Zizyphus vulgaris (p>0.05). There were not found remarkable differences in sensory properties (marbling, firmness and color) among the treatments. The results from the present study suggest that Zizyphus vulgaris could be a effective feed additive to improve meat quality of pigs. However, further research is needed to investigate effects of carcass characteristics.

TNF-α는 실험집단과 통제집단에서 유의한 차이를 보이지 않았다. 심혈관위험인자 중 혈당[F1=4.374, p<.05], 중성지방[F1=7.081, p<.01], 수축기 혈압[F1=6.420, p<.05] 등이 실험집단에서 유의하게 감소하고, HDL-Cholesterol [F1=4.430, p<.05]은 증가하였다. 건강 체력 중 심폐지구력[F1=5.099, p<.05], 평형성[F1=5.508, p<.05] 등이 실험집단에서 통계적으로 유의한 향상을 가져왔다. 고령자의 경우 부상이나 상해 등의 이유로 쉽게 접할 수 없는 경우가 많지만 본 연구를 통하여 고령자들에게 에어로빅댄스 무용 활동은 적합한 운동으로 입증되었으며, 심혈관위험인자 및 건강 체력에 효과가 있는 것으로 밝혀졌다. The purpose of this study was to investigate the effect of aerobic dance activities on TNF-α, cardiovascular risk factor, health physical fitness in elderly. The subjects for this study were 24 elderly people who participated in this experiment voluntarily. This subjects were divided into two groups: aerobic dance activities group(n=12), and control group(n=12). The experimental group was provided with 4 times per week of aerobic dance activities for 10 week periods each of which was taken 50 minutes. They were assessed for TNF-α, blood glucose, triglyceride, total cholesterol, HDL-Cholesterol, LDL-Cholesterol, SBP, DSP, cardio-respiratory endurance, muscle endurance, flexibility, balance, agility throughout pre-post testing in both group. The collected data were analyzed by repeated two-way ANOVA. The result indicated that. TNF-α was no significant differences between the aerobic dance activities group and control group. Aerobic dance activities group had significant difference in the blood glucose(p<.05), triglyceride(p<.01), HDL-Cholesterol(p<.05), SBP(p<.05) among the cardiovascular risk factor compared with control group. Cardio-respiratory endurance(p<.05), balance(p<.05), among the health physical fitness were significantly increased in the aerobic dance activities group compared with control group. This results suggest that aerobic dance activities may have benefit on cardiovascular risk factor and health physical fitness. But The research founded no connection between TNF-α and cardiovascular risk factor in the aerobic dance activities.

The protective effects of egg yolk atibodies obtained from chickens immunized with fimbrial antigens from ETEC 987P were evaluated in 14 and 21 d old pigs in which ETEC diarrhea was induced. For the Exp. 1, eight early-weaned pigs($5.00{\pm}0.5kg$ average BW and 14 d average age) and eight weaned pigs($6.00{\pm}0.5kg$ average BW and 21 d average age) were used to examine influence of egg yolk antibodies on growth performance and resistance to ETEC 987P infection. Dietary treatments included 1) administered of commercial egg yolk(14 d of age; CEY14), 2) administered of egg yolk antibodies(14 d of age; EYA14), 3) administered of commercial egg yolk(21 d of age; CEY21), 4) administered of egg yolk antibodies(21 d of age; EYA21). The 14 and 21 d old pigs were challenged with 2 ml of ETEC 987P at a dose of $10^{10}\;CFU\;ml^{-1}$ per weaned pigs. Weaned pigs treated with egg yolk antibodies recovered and pigs treated with egg yolk antibodies tended to increase average daily gain(P<0.05). Also, EYA12 and EYA21 treatments were reduced coli-form bacteria concentration and increased Lactobacilli sp. concentration from feces. For the Exp. 2, sixteen weaned pigs($6.00{\pm}0.5kg$ average daily gain BW and 21 d average age) were used to examine influence of yolk or white from egg containing antibodies on growth performance and resistance to ETEC 987P infection. Dietary treatments included l) administered of commercial egg yolk(CEY), 2) administered of commercial egg white(CEW), 3) administered of egg yolk antibodies(EYA), 4) administered of egg white antibodies(EWA). Pigs treated only with EYA showed signs of recovery. Also, EYA treatment showed the best average daily gain without significant differences (P>0.05). EYA treatment was reduced coli-form bacteria concentration increased and Lactobacilli sp. concentration from feces. In conclusion, egg yolk antibodies have protective effects from pigs in which ETEC diarrhea was induced.

구문론적 학습방벙에 특징매칭방법으로 보완된 2중 학습-인식 시스템에 대해 논하였다. 구문론적 학습방법으로는 학습부호열에 사용된 종단기호의 후속자를 분석하여 정규문법과 유한오토마타로 추론하였다. 특징매칭법으로는 연속적으로 보완된 16개의 상대적인 위치 좌표를 표준특징벡터로 사용하였다. On-line으로 입력되는 손으로 쓴 숫자데이타 500개에 대해 학습용 데이타의 수를 변화하면서 2중 학습-인식시스템의 성능을 실험하였다. 49개의 학습용 데이타로 학습한 결과 오인식은 하나도 발생하지 않았으며, 12개의 미인식만 발생하였다(인식율 97.6%). 실험결과 본 시스템은 최소한의 대화에 의해 완벽한 인식수행이 가능함을 보였다. A dual learning-recognition system, based on syntactic method coupled with feature matching method, is described For the syntactic method, regular grammar and finite automata are inferred by an analysis of successors of the terminal symbols in the learning strings For the feature matching method, the sequentially updated sixteen coordinates of the relative position are used as a standard feature vector. Performance of a dual learning-recognition system has been tested with changing the number of learning data for the 500 handwritten on-line input numeral data. In case of learning with 49 learning data, there is no uncorrectly recognized data and only 12 data rejections are occurred. (recognition rate 97.6%). The results show that the perfect recognition can be achieved by minimum interaction with this system.

홍종욱(Jong-Wook Hong),김인호(In-Ho Kim),권오석(Oh-Suk Kwon),이상환(Sang-Hwan Lee),이현우(Hyun-Woo Rhee),김을상(Eul-Sang Kim) 한국식품영양과학회 2001 한국식품영양과학회지 Vol.30 No.2

본 연구는 양파의 첨가에 따른 비육돈에서의 성장 및 혈청내 cholesterol 성상에 미치는 영향을 구명하기 위해 실시하였다. 사양시험은 3원 교잡종(Duroc×Yorkshire×Landrace) 비육돈 60두를 공시하였으며, 처리구로는 옥수수-대두박 기초사료에 양파 무첨가구(Con), 양파 1.0% 첨가구(ORB1)와 양파 2.0% 첨가구(ORB2)로 3 처리로 구성되었다. 전체 시험기간동안, 일당증체량과 일당식이섭취량은 대조구에 비해 양파의 첨가수준이 증가함에 따라 증가하였다(linear effect; p<0.01). 또한, 식이효율도 양파 첨가수준이 증가함에 따라 향상되었다(linear effect; p<0.01). 혈중 total cholesterol 농도는 대조구보다 양파 첨가수준에 따라 낮게 평가되었다(linear effect; p<0.06). 또한, 혈중 HDL-cholesterol 농도는 차이가 나타나지 않았지만, LDL-cholesterol 농도는 양파 첨가수준에 따라 유의적으로 낮은 수치를 나타내었다(linear effect, p<0.04; quadratic effect, p<0.09). 그러나, 혈중 triacylglyceride 농도에서는 처리구간에 유의적인 차이가 나타나지 않았다. 결론적으로 70~108 kg 비육돈에 있어 사료내 양파의 첨가는 성장촉진과 혈중 total cholesterol 농도 감소에 효과가 있는 것으로 사료된다. This study was conducted to evaluate the effects of dietary onion supplementation on the growth rate and blood cholesterol level in finishing pigs. Sixty Duroc×Yorkshire×Landrace pigs (69.75±0.79 kg average BW) were used in a 50 day growth assay. Dietary treatments included 1) corn-SBM (Con), 2) 1)+dietary onion rice bran 1.0% (ORB1), 3) 1)+dietary onion rice bran 2.0% (ORB2). For overall period, average daily weight gain and average daily feed intake were increased by the addition of dietary onion compared with Con (linear effect; p<0.01). Feed efficiency ratio was successfully improved by supplementation of dietary onion (linear effect; p<0.01). The total cholesterol concentrations in serum decreased as the concentration of onion in the diets was increased (linear effect, p<0.06). Also, LDL-cholesterol concentrations in serum tended to decrease in pigs fed onion than in those fed Con diet group (linear effect, p<0.04; quadratic effect, p<0.09). The HDL-cholesterol and triacylglyceride concentrations in serum were not influenced by the onion supplementation. The results obtained from this feeding trial suggest that the dietary onion supplementation for finishing pigs weighed 70 to 108 kg had improved growth performance and reduced total cholesterol level of serum.
