        Effect of Feeding Cyanidin 3-glucoside (C3G) High Black Rice Bran on Nutrient Digestibility, Blood Measurements, Growth Performance and Pork Quality of Pigs

        Kil, D.Y.,Ryu, S.N.,Piao, L.G.,Kong, C.S.,Han, S.J.,Kim, Y.Y Asian Australasian Association of Animal Productio 2006 Animal Bioscience Vol.19 No.12

        Two experiments were conducted to investigate the effect of feeding cyanidin 3-glucoside (C3G) high black rice bran on nutrient digestibility, blood measurements, growth performance and pork quality of pigs. In Exp. I, a total of fifteen pigs (19.91${\pm}$1.80 kg, average initial body weight) were used in assay of nutrient digestibility and blood measurements. All pigs were allotted to 5 treatments with 3 replicates according to a completely randomized design (CRD) in an individual metabolic crate. Treatments included 1) CON: basal diet, 2) BRB-2: basal+brown rice bran 2%, 3) BRB-4: basal+brown rice bran 4%, 4) CRB-2: basal+C3G high black rice bran 2% and 5) CRB-4: basal+C3G high black rice bran 4%. The digestibility of dry matter (DM), crude protein (CP), crude fat (CF), crude ash (CA) and crude fiber (CF) was not affected by dietary treatments. Serum triglyceride (TG) and high density lipoprotein (HDL) cholesterol concentrations were not affected by addition of C3G high black rice bran. However, at the end of experiment, pigs fed rice bran showed decreased tendency in total cholesterol concentration. Especially pigs fed C3G high black rice bran showed significantly lower total cholesterol concentration compared to pigs fed brown rice bran (p<0.03). There was numerically lower total cholesterol concentration with increasing levels of black rice bran in the diet. In terms of serum glutamate oxaloacetate transaminase (GOT) and glutamate pyruvate transaminase (GPT), there were no significant differences among treatments, even though pigs fed CRB-4 showed the lowest GOT concentration compared to other pigs. In Exp. II, sixteen finishing pigs (average initial body weight 89.96${\pm}$0.35 kg) were divided into 4 treatments to investigate the effect of feeding C3G high black rice bran on growth performance and pork quality. There were no significant differences in average daily gain (ADG), average daily feed intake (ADFI) and feed conversion ratio (FCR) among the treatments. Pigs fed C3G high black rice bran showed numerical decrease in ADG and increase in FCR while not effecting feed intake. There was no significant difference in live weight, carcass weight, carcass rate, backfat thickness and carcass grade. However, pigs fed C3G high black rice bran tended to show lower backfat thickness than pigs fed basal diet. Pigs fed C3G high black rice bran showed a tendency of decreased TBA value than pigs fed basal diet, although there was no overall significant difference among treatments. In conclusion, nutrient digestibility, blood measurements, growth performance and pork quality were not significantly affected by feeding C3G high black rice bran to pigs. However, C3G high black rice bran might have an effect on lowering serum total cholesterol and decrease the TBA value in pork compared to control group and these effects might be due to high concentration of antioxidative compounds in C3G high black rice bran.

        재래한우의 보존을 위한 혈청 및 혈구단백질의 유전적 다형현상

        한상기(S . K . Han),윤희섭(H . S . Yoon),정의룡(E . Y . Chung),신유철(Y . C . Shin),변희대(H . D . Byun) 한국축산학회 1995 한국축산학회지 Vol.37 No.1

        Biochemical polymorphisms of five red cell and semen proteins, Hemoglobin(Hb), Transferrin(Tf), Post-transferrin 2(Ptf2), Post-albumin(Pa) and Albumin(Alb) as genetic markers in Korean cattle were analyzed by Starch and Polyacryamide gel electrophoresis and their phenotypes, genotypes and gene frequencies were estimated in order to analysis the genetic constitution of Korean native cattle population. In the Hemoglobin(Hb) locus four different phenotypes AA, AB, BB and CH were observed and assumed to be controlled by four different alleles designated Hb^A, Hb^B, Hb^C and Hb^H, and the Hb^H type was rare variant of Korean native cattle. The observed distribution of phenotypes were 73.37% for AA type, 23.37% for AB type. 2.72% for BB type and 0.54%r for CH type. Gene frequencies of Hb^A, Hb^B, Hb^C and Hb^H were 0.8505, 0.1440, 0.0027 and 0.0027. Semen Transfetrin(Tf) locus, 11 different phenotypes AA, AD₁, AD₂, AE, AH, D₁D₁, D₁D₂, D₁E, D₂H, D₂D₂, D₂E, EE and EH type were identified, which considered to be controlled by codominant alleles TF,^A Tf^D, Tf^D, Tf^E and Tf^H at a single locus. The frequencies of Tf genotypes AD₁, D₁E, D₁D₂, D₂E, AA, AE, D₁D₂, AD₂, D₁D₁, EE, AH, D₂H and EH were found to be 16.30, 13.33, 11.85, 10.37, 9.69, 8.15, 7.41, 9.63, 5.93, 4.44, 1.48, 0.74 and 0.01%, respectively. Gene frequencies of TF^A, Tf^(D1) Tf^(D2) and Tf^H were 0.2741, 0.2704, 0,2333, 0.2074 and 0.0148, respectively. And TfH gene were newly identified in Korean native cattle. Considering Post-transterrin 2 locus, three different phenotypess FF, FS and SS were identified, which considers to he controlled by two alleles Ptf^F and Ptf^S at a single autosomal locus. The frequencies of Rf genotypes FS, FF and SS were found to be 51.06. 36.88 and 12.06%n, respectively and gene frequencies of Ptf^F and Ptf^S were 0.6241 and 0.3759. In the Postalbumin(Pa) locus, three different phenotypes FF, FS and SS type were observed to be genetically controllled by Pa^F and Pa^S gene. And genotypes frequencies FS. FF amd SS type were 48.65, 36.(H and 1_5.32%, respectively. The gene frequencies of Pa^F and Pa^S were 0.6036 and 0.3964. The Albumin(Alb) locus were observed to lack any individual variation. Therefore, this locus were defined to be monomorphic. In comparison of genetic distance and dendogram calculated from the gene frequencies, close relationship was obtained between the Japanese cattle and the Korean cattle.

        Recent Advances in Amino Acid and Energy Nutrition of Prolific Sows - Review -

        Boyd, R.D.,Touchette, K.J.,Castro, G.C.,Johnston, M.E.,Lee, K.U.,Han, In K. Asian Australasian Association of Animal Productio 2000 Animal Bioscience Vol.13 No.11

        Prolific females require better nutrition and feeding practice because of larger litter size and the substantial decline in body fat. Life-time pig output will be compromised if body protein and fat are not properly managed. First litter females are especially vulnerable because they can loose ${\geq}15%$ of whole-body protein. Conservation of body protein mass during first lactation minimizes wean to estrus interval and increases second litter size (up to 1.2 pigs). The ability to influence litter-size by amino acid nutrition is a new dimension in our understanding. A P2 fat depth below 12 mm at farrow and below 10 mm at wean compromised wean to estrus interval (>2 d) and next litter size (0.5 to 1.5 pigs) in sows. It is now clear that a 'modest' excess of feed during the first 72 h of pregnancy decreases embryo viability so that the potential for an increased litter size at birth is not realized. The capacity for milk production by prolific young sows is 25% higher than the standard used previously (NRC, 1988). First litter females averaged 9.82 kg milk/d for a 21 d lactation. Second and third litter counterparts averaged 10.35 kg/d. Milk production was 95% of peak by 10 d of lactation and sows were in greatest negative energy and lysine balance during the first 6 d. Nearly 45% of the total loss in body protein occurred within the first 6 d, but this could reduced to 30-35% by using a more aggressive feeding strategy after parturition. There appear to be 2 phases in lactation for lysine need (d 2-12 vs 12-21). Feeding to the higher level alleviates the second litter size decline. The lysine requirement for lactation can be predicted with accuracy, but we are not able to predict the second limiting amino acid. Mammary uptake of valine relative to lysine and recent work with practical diets suggest that the recent NRC (1998) pattern is realistic and that threonine and valine could be co-limiting for corn-soy diets for prolific sows nursing 10-11 pigs. Empirical studies are needed to refine the ideal pattern so that synthetic lysine can be used with more confidence. Milk fat output for the elite sow is extraordinary and poses an unnecessarily high energetic cost. Methods that reduce mammary fat synthesis will benefit the sow and may enhance piglet growth.

        Protein Profile in Corpus Luteum during Pregnancy in Korean Native Cows

        Chung, H.J.,Kim, K.W.,Han, D.W.,Lee, H.C.,Yang, B.C.,Chung, H.K.,Shim, M.R.,Choi, M.S.,Jo, E.B.,Jo, Y.M.,Oh, M.Y.,Jo, S.J.,Hong, S.K.,Park, J.K.,Chang, W.K. Asian Australasian Association of Animal Productio 2012 Animal Bioscience Vol.25 No.11

        Steroidogenesis requires coordination of the anabolic and catabolic pathways of lipid metabolism, but the profile of proteins associated with progesterone synthesis in cyclic and pregnant corpus luteum (CL) is not well-known in cattle. In Experiment 1, plasma progesterone level was monitored in cyclic cows (n = 5) and pregnant cows (n = 6; until d-90). A significant decline in the plasma progesterone level occurred at d-19 of cyclic cows. Progesterone level in abbatoir-derived luteal tissues was also determined at d 1 to 5, 6 to 13 and 14 to 20 of cyclic cows, and d-60 and -90 of pregnant cows (n = 5 each). Progesterone level in d-60 CL was not different from those in d 6 to 13 CL and d-90 CL, although the difference between d 6 to 13 and d-90 was significant. In Experiment 2, protein expression pattern in CL at d-90 (n = 4) was compared with that in CL of cyclic cows at d 6 to 13 (n = 5). Significant changes in the level of protein expression were detected in 32 protein spots by two-dimensional polyacrylamide gel electrophoresis (2-DE), and 23 of them were identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS). Six proteins were found only in pregnant CL, while the other 17 proteins were found only in cyclic CL. Among the above 6 proteins, vimentin which is involved in the regulation of post-implantation development was included. Thus, the protein expression pattern in CL was disorientated from cyclic luteal phase to mid pregnancy, and alterations in specific CL protein expression may contribute to the maintenance of pregnancy in Korean native cows.

      • Interleukin-18, transforming growth factor-β, and vascular endothelial growth factor gene polymorphisms and susceptibility to primary glomerulonephritis

        Choi, H.-J.,Cho, J.-H.,Kim, J.-C.,Seo, H.-J.,Hyun, S.-H.,Kim, G.-H.,Choi, J.-Y.,Choi, H.-J.,Ryu, H.-M.,Cho, J.-H.,Park, S.-H.,Kim, Y.-L.,Han, S.,Kim, C.-D. Blackwell Publishing Ltd 2010 Tissue antigens Vol.76 No.4

        <P>Several studies have showed an association of gene polymorphisms with the development of glomerulonephritis (GN). We investigated the effects of gene polymorphisms on the development of GN by analyzing polymorphisms in the interleukin (IL)-18, transforming growth factor (TGF)-β, and vascular endothelial growth factor (VEGF) genes in Korean patients with primary GN. The study included 146 normal subjects (controls) and 100 patients diagnosed with primary GN by kidney biopsy. The gene polymorphisms A-607C and G-137C in <I>IL-18</I>, C-509T and T869C in <I>TGF-</I>β<I>1</I>, and C-2578A and C405G in <I>VEGF</I> were investigated in DNA extracted from peripheral blood. Significant differences were observed between the GN and control groups in the genotype and allele frequencies of A-607C <I>IL-18</I> and C405G <I>VEGF</I>. The frequencies of the <I>IL-18</I>−607CC genotype [<I>P</I> = 0.001, odds ratio (OR) = 2.473] and the <I>VEGF</I> 405GG genotype (<I>P</I> = 0.001, OR = 2.473) were significantly increased in the GN group. The combination of <I>IL-18</I>−607CC+ and <I>VEGF</I> 405GG+ genotypes had a higher risk for developing GN in comparison with the combination of <I>IL-18</I>−607CC− and <I>VEGF</I> 405GG− genotypes (<I>P</I> < 0.001, OR = 8.642). In the haplotype analysis of the <I>IL-18</I> gene, the CG haplotype was significantly more frequent in the GN group than the control group (61.5% <I>vs</I> 46.9%, <I>P</I> = 0.002). These results show that the −607CC genotype of the <I>IL-18</I> gene and the 405GG genotype of the <I>VEGF</I> gene are associated with susceptibility to and the development of primary GN.</P>

        돼지사료중 제주 화산암 분말(Scoria)과 Zeolite 가 산육능력에 미치는 영향

        한인규,양창범,김진동,조원탁,이지훈 한국동물자원과학회 2000 한국축산학회지 Vol.42 No.4

        This study was conducted to investigate the effect of Cheju scoria and zeolite on the growth performance, nutrient digestibility and excretion, carcass characteristics of pigs and to evaluate the value of Cheju scoria as a feed additive to reduce environmental pollutions. A total of 63 weaned piglets [D (♂) × LY (♀)] averaging 8.3±0.31 ㎏ of body weight were assigned to the feeding trial for 150 days and 16 growing barrows (averaging 40.5±0.57; four pigs per treatment) to the metabolic trial. The weaned piglets in the feeding trial were divided into three groups and treated in three replicates of seven pigs (4 gilts and 3 barrows) with one of the three experimental diets; con-soybean meal basal (BD), 3% Cheju scoria (CS), and 3% zedite diets (ZD). The based diets were formulated to contain 3,657 kcal DE/㎏ (CP 18.87%), 3,620 kcal DE/㎏ (CP 16.00%) and 3,473 kcal DE/㎏ (CP 15.97%) for starter, grower and finisher, respectively. 3% of com in basal diets was replaced by Cheju scoria or ziolite. All the pigs were slaughtered for carcass analysis at the end of experiment. During nursery period (0 to 39d), average daily gain (ADG) was significantly higher in CS than in BD and ZD (P$lt;0.05), and feed efficiencies in CS and ZD were better than that in BD. For growing period (40 to 109d), ADG and average daily feed intake (ADFI) were significantly higher in CS and ZD than in BD (P$lt;0.05)$gt; but feed efficiencies were not statistically different among treatments. For finishing period (109 to 150d), ADG was significantly higher in CS and ZD than in BD, and ADFI was not affected by the treatments. However, CS showed better feed efficiency than the others (P$lt;0.05). For the entire experimental period (0 to 150d), CS and ZD tended to be higher in ADG and ADFI compared to that of BD, but no significant differences in feed efficiency were observed among treatments. Dry matter (DM), crude protein (CP) and phosphorus (P) digestibilities were significantly higher in CS than that of BD, and there was no difference in nutrient digestibility between ZD and BD. Nitrogen (N) and P excretion were significantly lower in CS than in BD during the nursery period (P$lt;0.05). For the growing period, BD showed significantly lower N and P excretion compared to the control (P$lt;0.05). N excretion was significantly lower in CS and ZD than in BD, and P excretion was lowest in CS for the finishing period. There were no differences in carcass weight and back fat thickness among the treatment. However, carcass grade was much better in CS than in the others. With regard to meat color, Hunter L value was highest in CS, but there were no differences in Hunter a and b value between CS and BD. The results from the present study suggest that Cheju scoria could be a effective feed additive to reduce N and P excretion and to improve growth performance and meat quality of pigs. However, further research is needed to investigate the exact mode of action of Cheju scoria and optimal level of dietary supplementation.

      • OGLE-2016-BLG-1469L: Microlensing Binary Composed of Brown Dwarfs

        Han, C.,Udalski, A.,Sumi, T.,Gould, A.,Albrow, M. D.,Chung, S.-J.,Jung, Y. K.,Ryu, Y.-H.,Shin, I.-G.,Yee, J. C.,Zhu, W.,Cha, S.-M.,Kim, S.-L.,Kim, D.-J.,Lee, C.-U.,Lee, Y.,Park, B.-G.,Soszyń,ski, American Astronomical Society 2017 The Astrophysical journal Vol.843 No.1

        <P>We report the discovery of a binary composed of two brown dwarfs, based on the analysis of the microlensing event OGLE-2016-BLG-1469. Thanks to the detection of both finite-source and microlens-parallax effects, we are able to measure both the masses M-1 similar to 0.05M(circle dot) and. M-2 similar to 0.01M(circle dot), and the. distance D-L similar to 4.5 kpc, as well as the projected separation a(perpendicular to) similar to 0.33 au. This is the third brown-dwarf binary detected using the microlensing method, demonstrating the usefulness of microlensing in detecting field brown-dwarf binaries with separations of less than 1 au.</P>

      • 대학생 커플 간의 성 의사소통 양상에 따른 성 태도, 성적 자율성 및 성 만족도의 상관관계에 관한 연구

        이은하,이지연,정지영,강시원,한현민,김소연,김동미,방소현,박예찬,지혜민 이화여자대학교 간호과학대학 2015 이화간호학회지 Vol.- No.49

        Purpose: The purpose of this study was to investigate sexual communication among college student couples and to analyze the relationship among sexual communication, sexual attitude, sexual autonomy and sexual satisfaction. Methods: Using a descriptive correlation study design, 281 college student couples were recruited through convenience random sampling from September 18th to October 3rd, 2014. Data were analyzed using average, standard deviation, percentage, t-test, ANOVA, Scheffe test, Duncan’s test and Pearson’s correlation using the SPSS 21.0 program. Results: In both genders, it is identified that high scores for sexual communication is related to sexual openness (male: R= .347, p<0.01 / female: R=.337, p<0.01) higher sexual satisfaction (male: R= .349, p<0.01 / female: R=.336, p<0.01) and sexual autonomy (male: R= .336, p<0.01 / female: R=.364, p<0.01). The same outcome is found when each male and female are grouped as a couple. Among sub-categories of sexual attitude, sexual pleasure was related to sexual communication the most in male (R=.337, p<0.01), female groups (R=.317, p<0.01) and couples (R=.402, p<0.01). Among sub-categories of sexual satisfaction, psychological factor was related to sexual communication the most in the male group (R=.342, p<0.01) and interactive factor was related to sexual communication the most in the female group (R=.317, p<0.01) and couples (R=.402, p<0.01). Conclusion: The significance of this research is that the relations of sexual communication with the other three dependent variables among each gender and couples are shown. In addition, this study suggests the importance of sexual communication between couples which will lead to healthier and better quality of sexual relationships. However, with the lack of sufficient advanced research, there are limitations of analyzing each variables divided by demographic characteristics.

      • 羚洋角 Capricornidis Cornu 製劑가 家兎血淸中 脂質含量變化에 미치는 影響에 關한 硏究

        韓大燮,鄭址昌,朴泰權,姜孝信 慶熙大學校 1972 論文集 Vol.7 No.-

        The effect of crude drug preparation containing Capricornidis Cornu (C.C.) on the amount of total cholesterol, triglycerides, and phospholipid in serum from rabbit were observed. The preparations were extracted by methanol, and extracted samples were orally administrated to the rabbits fasted for three days. After three days starvation, the amounts of total cholesterol and triglycerides in serum of the rabbit were markedly increased, while phospholipid was slightly decreased. The increased amounts of total cholesterol and triglyceride were gradually decreased by administration of the extracted samples, and were returned to the control levels after 15 days. However, the amount of phospholipid was increased to higher than the control levels by administration of the drugs. The crude drug preparations containing C.C. produced the most significant results, in comparison with the experimental groups treated by C.C. alone, or crude drugs without C.C.

      • Direct Reprogramming of Fibroblasts into Neural Stem Cells by Defined Factors

        Han, D.,Tapia, N.,Hermann, A.,Hemmer, K.,Hoing, S.,Arauzo-Bravo, Marcos J.,Zaehres, H.,Wu, G.,Frank, S.,Moritz, S.,Greber, B.,Yang, J.,Lee, H.,Schwamborn, Jens C.,Storch, A.,Scholer, Hans R. Cell Press 2012 Cell stem cell Vol.10 No.4

        Recent studies have shown that defined sets of transcription factors can directly reprogram differentiated somatic cells to a different differentiated cell type without passing through a pluripotent state, but the restricted proliferative and lineage potential of the resulting cells limits the scope of their potential applications. Here we show that a combination of transcription factors (Brn4/Pou3f4, Sox2, Klf4, c-Myc, plus E47/Tcf3) induces mouse fibroblasts to directly acquire a neural stem cell identity-which we term as induced neural stem cells (iNSCs). Direct reprogramming of fibroblasts into iNSCs is a gradual process in which the donor transcriptional program is silenced over time. iNSCs exhibit cell morphology, gene expression, epigenetic features, differentiation potential, and self-renewing capacity, as well as in vitro and in vivo functionality similar to those of wild-type NSCs. We conclude that differentiated cells can be reprogrammed directly into specific somatic stem cell types by defined sets of specific transcription factors.
