Growth characteristics and palatability by different harvesting dates were measured in order to determine its availability and effective storage period when sorghum × sudangrass hybrid were stored as foggage. Experiment was carried out with six treatments as follows; T1, T2 and T3 were foggaged at 120, 160 and 200㎝ in plant length and T4, T5 and T6 were foggaged at boot, milk and dough stage on 7 october after regrowth respectively. Rice straw was offered to examine the relative palatability a, control. 1. Growth characteristics such as plant length, leaf length, leaf width, leaf number and stem hardness were decreased with prolongation of foggage period at all treatments. Especially, decrease and falling ratio were a heigher at T5 and T6 than the other treatments. 2. Greeness grade of leaf showed fast decoloration at TI and T2 treatments, but stem showed fast decoloration at TS and T6 treatments. Leaf and stem decolorized in mid-October and mid-november in all treatments. 3. Leaf ratio was deceased with prolongation of foggage period, but stem showed gradually increase. Grain ratio was stable increase at T6 treatments, but not at T5 treatment, 4. Dry matter contents of leaf and grain were stable increased at all treatment but stem was multifarious according to weather conditions. 5. Changes of palatability were high at T1, T2 and T3 treatments untill mid-October, but T4 treatment and rice straw showed high in early December. 6. According to the results obtained in this study, it was suggested that when sorghum x sudangrass hybrid is used as foggage, foggaging period would be suitable until mid-november and growth stage for foggaging would be recommendable from T2 to boot stage for maximum availability.

본 실험은 기존 사슴사료에 있어서 육계분 발효사료의 대체 가능성을 검토하기 위해 숫사슴에 있어서 육계분 발효사료의 첨가수준을 0, 15 및 30%로 달리하여 소화율, 증체량, 건물채식량 및 질소출납에 미치는 영향을 검토하였다. 모든 처리구에서 실험사슴들은 비슷한 수준의 채식량을 나타내어 건물기준으로 체중의 약 3% 정도의 채식량을 기록하고 있어 육계분 발효사료를 30%까지 첨가한 경우 숫사슴의 채식 기호도에는 부정적인 영향이 나타나지 않는 것으로 판단되었다. 건물소화율은 Control이 76.5%로 가장 높았고, T2가 70.3%로 가장 낮아 유의성(P<0.05)이 인정되었다. 조단백질의 경우도 Control구가 75.8%로 가장 높은 소화율을 나타내었으며, T2가 70.2%로 가장 낮은 소화율을 나타내어 처리간에 유의성(P<0.05)이 인정되었다. 조섬유 소화율은 Contol구 70.8%, T1구 62.7%, T2구 56.0%로 육계분 발효사료의 첨가수준이 높아짐에 따라 조섬유 소화율이 저하되어 Control구와의 사이에 유의성(P<0.05)이 인정되었다. 건물 및 가소화 건물섭취량 모두 육계분 발효사료의 첨가수준이 높아질수록 약간씩 저하되는 경향은 있었으나 그 차이에 대한 유의성은 인정되지 않았다. 실험사슴들의 일당 증체량은 T1구에서 가장 높았으며 Control구에서 가장 낮았으나 처리간의 차이는 유의성이 인정되지 않았다. 질소섭취량은 T1구가 40.2g으로 가장 많았으며 T2구가 38.0g으로 가장 낮았으나 처리간의 유의성은 인정되지 않았다. 분 중 질소의 양은 T2구에서 가장 높았으며 뇨 중 질소의 양은 Control구가 가장 높았다(P<0.05). 체내 질소 축적량은 T1구에서 가장 높았으나 나머지 처리구들과 비슷한 수준을 유지했다. To determine nutritive value and suitability of deep-stacked broiler litter for deer, influence of supplementary levels of broiler litter on digestibility, dry matter intake, and nitrogen balance was investigated in male spotted deer (Cervus nippon) fed a commercial mixed(complete) ration. The deep-stacked and ground broiler litter was supplemented at the level of 0%(Control). 15%(TI) and 30%(T2) on the basis of fresh matter to the mixed ration. All treatments had similar palatability at about 3% body weigh of dry matter intake. Dry matter digestibility was highest in Control and lowest in T2(P<0.05). Digestibility of crude protein was lowest(P<0.05) in T2. Dry matter and digestible dry matter intake was similar in all treatments. Daily body weight gain was not affected by treatments. Feeding 15 or 30% of broiler litter to male deer resulted in similar nitrogen intake. fecal nitrogen excretion and daily nitrogen retention(g/d), compared with feeding Control. These results suggest that up to 30% of broiler litter may be fed to male deer without deleterious effects on deer performance.

Investigation of the Structural, Electrical, and Optical Properties of MnAl2Se4 Layers Grown Using the Hot-Wall Deposition Technique

S. H. You,K. J. Hong,J. W. Jeong,T. S. Jeong,C. J. Youn,J. D. Moon 한국물리학회 2016 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.69 No.4

MnAl2Se4 layers were grown using the hot-wall deposition technique with an attached reservoir tail. Precise control of the vapor pressure in the reservoir was thought to play an important role in the grown of a stoichiometric layer. From the relation between the reciprocal temperature and the carrier concentration, we extracted the dominant trap level as 96.1 meV in the high-temperature region and 13.9 meV in the middle-temperature region. Thus, from a log-log plot between the mobility and the temperature, the mobility showed the different temperature-dependent decreases of the mobility at temperatures above 100 K: T−1/2 in the temperature range of 100 < T < 225 K and T−3/2 in the temperature of T > 225 K. The mobility decreased in proportion to T1 in the low-temperature range of T < 100 K. By analyzing the optical absorption results, the bandgap variation matched Eg(T) = Eg(0) − 3.19 × 10−3 T2/(T + 488) well, where Eg(0) is estimated to be 3.5616 eV. Consequently, low-temperature growth of MnAl2Se4 layers was achieved by using the hot-wall deposition technique.

15-lipoxygenase metabolites play an important role in the development of a T-helper type 1 allergic inflammation induced by double-stranded RNA

Jeon, S. G.,Moon, H.-G.,Kim, Y.-S.,Choi, J.-P.,Shin, T.-S.,Hong, S.-W.,Tae, Y.-M.,Kim, S.-H.,Zhu, Z.,Gho, Y. S.,Kim, Y.-K. Blackwell Publishing Ltd 2009 Clinical and experimental allergy Vol.39 No.6

<P>Summary</P><P>Background</P><P>We recently demonstrated that the T-helper type 1 (Th1) immune response plays an important role in the development of non-eosinophilic inflammation induced by airway exposure of an allergen plus double-stranded RNA (dsRNA). However, the role of lipoxygenase (LO) metabolites in the development of Th1 inflammation is poorly understood.</P><P>Objective</P><P>To evaluate the role of LO metabolites in the development of Th1 inflammation induced by sensitization with an allergen plus dsRNA.</P><P>Methods</P><P>A Th2-allergic inflammation mouse model was created by an intraperitoneal injection of lipopolysaccharide-depleted ovalbumin (OVA, 75 μg) and alum (2 mg) twice, and the Th1 model was created by intranasal application of OVA (75 μg) and synthetic dsRNA [10 μg of poly(I : C)] four times, followed by an intranasal challenge with 50 μg of OVA four times. The role of LO metabolites was evaluated using two approaches: a transgenic approach using 5-LO<SUP>−/−</SUP> and 15-LO<SUP>−/−</SUP> mice, and a pharmacological approach using inhibitors of cysteinyl leucotriene receptor-1 (cysLTR1), LTB4 receptor (BLT1), and 15-LO.</P><P>Results</P><P>We found that the Th1-allergic inflammation induced by OVA+dsRNA sensitization was similar between 5-LO<SUP>−/−</SUP> and wild-type (WT) control mice, although Th2 inflammation induced by sensitization with OVA+alum was reduced in the former group. In addition, dsRNA-induced Th1 allergic inflammation, which is associated with down-regulation of 15-hydroxyeicosateraenoic acids production, was not affected by treatment with cysLTR1 or BLT1 inhibitors, whereas it was significantly lower in 12/15-LO<SUP>−/−</SUP> mice compared with WT control mice. Moreover, dsRNA-induced allergic inflammation and the recruitment of T cells following an allergen challenge were significantly inhibited by treatment with a specific 15-LO inhibitor (PD146176).</P><P>Conclusion</P><P>15-LO metabolites appear to be important mediators in the development of Th1-allergic inflammation induced by sensitization with an allergen plus dsRNA. Our findings suggest that the 15-LO pathway is a novel therapeutic target for the treatment of virus-associated asthma characterized by Th1 inflammation.</P>

Species and gamete-specific fertilization success of two sea urchins under near future levels of pCO₂

Sung, C.G.,Kim, T.W.,Park, Y.G.,Kang, S.G.,Inaba, K.,Shiba, K.,Choi, T.S.,Moon, S.D.,Litvin, S.,Lee, K.T.,Lee, J.S. Elsevier 2014 Journal of marine systems Vol.137 No.-

Since the Industrial Revolution, rising atmospheric CO<SUB>2</SUB> concentration has driven an increase in the partial pressure of CO<SUB>2</SUB> in seawater (pCO<SUB>2</SUB>), thus lowering ocean pH. We examined the separate effects of exposure of gametes to elevated pCO<SUB>2</SUB> and low pH on fertilization success of the sea urchin Strongylocentrotus nudus. Sperm and eggs were independently exposed to seawater with pCO<SUB>2</SUB> levels ranging from 380 (pH7.96-8.3) to 6000ppmv (pH7.15-7.20). When sperm were exposed, fertilization rate decreased drastically with increased pCO<SUB>2</SUB>, even at a concentration of 450ppmv (pH range: 7.94 to 7.96). Conversely, fertilization of Hemicentrotus pulcherrimus was not significantly changed even when sperm was exposed to pCO2 concentrations as high as 750ppmv. Exposure of S. nudus eggs to seawater with high pCO<SUB>2</SUB> did not affect fertilization success, suggesting that the effect of increased pCO<SUB>2</SUB> on sperm is responsible for reduced fertilization success. Surprisingly, this result was not related to sperm motility, which was insensitive to pCO<SUB>2</SUB>. When seawater was acidified using HCl, leaving pCO<SUB>2</SUB> constant, fertilization success in S. nudus remained high (>80%) until pH decreased to 7.3. While further studies are required to elucidate the physiological mechanism by which elevated pCO<SUB>2</SUB> impairs sperm and reduces S. nudus fertilization, this study suggests that in the foreseeable future, sea urchin survival may be threatened due to lower fertilization success driven by elevated pCO<SUB>2</SUB> rather than by decreased pH in seawater.

Association of tumor necrosis factor- gene polymorphisms with advanced stage endometriosis

Lee, G. H.,Choi, Y. M.,Kim, S. H.,Hong, M. A.,Oh, S. T.,Lim, Y. T.,Moon, S. Y. Oxford University Press 2008 Human reproduction Vol.23 No.4

<P>BACKGROUND: This study was performed to investigate whether specific haplotypes and several single nucleotide polymorphisms in the promoter region of the tumor necrosis factor (TNF)-alpha gene are associated with the risk of advanced stage endometriosis in a Korean population. METHODS: This study comprised women with (n = 246) or without (n = 248) endometriosis. The TNF:g.[-1031T > C], TNF:g.[-863C > A] and TNF:g.[-857C > T] polymorphism in the TNF-alpha gene were assessed by PCR-restriction fragment length polymorphism analysis, which utilized digestion by BbsI, HypCH4IV and HypCH4IV restriction enzymes, respectively. In silico haplotypes were deduced by using the Haploview version 3.32. RESULTS: The genotype distribution of TNF:g.[-1031T > C] was significantly different between total endometriosis patients and the controls (T/T of 56.9 versus 60.1%, T/C of 35.4 versus 37.5% and C/C of 7.7 versus 2.4%, respectively, P = 0.027). This difference at the TNF:g.[-1031T > C] tends to increase in Stage IV endometriosis (P = 0.01). However, there was no difference in the TNF:g.[-863C > A] and TNF:g.[-857C > T] site between the two groups. Even when the endometriosis cases were subdivided into American Society for Reproductive Medicine Stages III and IV, genotype differences were not found. The CC homozygote at TNF:g.-863 was more frequently found in the controls than Non-CC group (P = 0.04; odds ratio = 0.67; 95% confidence interval = 0.45-0.98). All haplotypes and diplotypes, deduced by in silico analysis, showed no association with subgroups or controls. CONCLUSIONS: Our results suggest that the genotype frequencies at the TNF:g.[-1031T > C] and the TNF:g.[-863C > A] sites may be associated with advanced stage endometriosis in the Korean population.</P>
