ObjectiveaaThis study compares the efficacy of the cholinesterase inhibitor (ChEI) galantamine on cognition in patients with mild-to-moderate Alzheimer’s dementia (AD) who were either naïve to ChEI drugs or who had failed a trial of the ChEI donepezil. MethodsaaOutpatients with AD were sequentially referred for screening and enrollment. Current outpatients who had taken donepezil for at least 6 months without demonstrated efficacy on cognition were switched to galantamine (switched group). New outpatients with no ChEI prescription history were classified as the naïve group and were given galantamine. The primary outcome measures for the betweengroup comparison were response rate on cognition at 26 and 52 weeks (categorical) and change on the Korean version of the Alzheimer’s Disease Assessment Scale-cognitive subscale (dimensional). Secondary cognitive outcomes were measured using the subset of frontal executive function and the Korean Mini-Mental State Examination. ResultsaaSeventy outpatients were enrolled and 66 were analyzed by Intent-to-treat (ITT). There were 42 cases in the naïve group and 24 in the switched group. Response rates did not differ at 26 weeks (71.4% naïve vs. 58.3% switched; p=0.277) or at 52 weeks (59.5% naïve vs. 41.6% switched; p=0.162). No significant differences were observed in the pattern of change over the 52 weeks on the primary and secondary cognitive scales. ConclusionaaAs the efficacy of galantamine on cognition was not inferior in the switched group compared to that in the naïve group, switching ChEI drugs is clinically feasible for non-responding patients with mild-to-moderate AD.

황태영,지희정,김기용,이상훈,이기원,최기준,Hwang, Tae-Young,Ji, Hee Chung,Kim, Ki Yong,Lee, Sang-Hoon,Lee, Ki-Won,Choi, Gi Jun 한국초지조사료학회 2015 한국초지조사료학회지 Vol.35 No.2
본 시험은 새로운 여름 사료작물인 케나프(kenaf; Hibiscus dannabinus L.)의 생육특성, 수량성 및 품질을 다른 사료작물과 비교할 목적으로 2013년부터 2014년까지 2년간에 걸쳐 축산과학원 축산자원개발부 초지사료과 내의 시험포장에서 수행하였다. 중부지역에서 케나프(홍마 300), 옥수수(광평옥) 및 수수${\times}$수단그라스(점보)의 생육특성 및 품질을 비교한 결과를 요약하면 다음과 같다. 당도는 홍마 300이 $5.4Brix^{\circ}$로 광평옥보다 $1Brix^{\circ}$, 점보보다 $2.9Brix^{\circ}$ 높았다. 출현율과 도복은 세 작물 모두 각각 80% 이상, 1.5 이상으로 양호하게 나타났다. 생초수량은 점보가 홍마 300보다 12% 높았으며, 건물중은 홍마 300이 제 작물 중 유의성 있게 가장 높게 나타났다(p<0.05). 하지만, TDN 수량은 홍마 300이 광평옥보다 13% 유의성 있게 낮았다 (p<0.05). ADF 및 NDF 함량은 홍마 300이 57.8%, 69.5%로 가장 높았으며 TDN 함량 및 건물소화율은 43.3% 및 44.4%로 가장 낮았다. 따라서 본 연구결과를 토대로 볼 때 케나프인 홍마 300은 건물수량은 높지만 사료 품질에서 광평옥 및 점보보다 많이 낮았다. 그 결과 TDN 수량성은 광평옥보다 13% 낮은 결과를 얻었다. 이상의 결과를 종합하여 볼 때, 새로운 사료작물인 케나프는 단위면적당 생초 및 건물수확량은 옥수수보다 높지만, 건물소화율 및 TDN 함량이 낮아 TDN 수량은 옥수수보다 낮은 것으로 나타났다. 결과적으로 홍마 300은 높은 수량성을 가지고 있지만 낮은 사료가치를 가지고 있는 것으로 나타났다. This study was conducted from 2013 to 2014 in the middle region of Korea to compare the agronomic characteristics, forage production, and quality of kenaf, maize, and a sorghum ${\times}$ sudangrass hybrid. The three crops used in this study were kenaf "Hongma 300," maize "Kwangpyeongok," and the sorghum ${\times}$ sudangrass hybrid "Jumbo" (headless type). The sugar contents of the kenaf, maize, and sorghum ${\times}$ sudangrass hybrid were 5.4%, 4.4%, and 2.5%, respectively. The emergence rates and lodgings of the three crops were sound, as they were more than 80% and 1.5, respectively. The fresh yields of kenaf, maize, and the sorghum ${\times}$ sudangrass hybrid were 117,521 kg/ha, 73,336 kg/ha, and 133,334 kg/ha, respectively, and the dry matter (DM) yields were 28,598 kg/ha, 19,951 kg/ha and 20,083 kg/ha, respectively. The DM yield of kenaf was significantly the highest among the three crops (p<0.05). However, the total digestible nutrients (TDN) contents of the kenaf, corn, and sorghum ${\times}$ sudangrass hybrid were 43.3 %, 72.0 %, and 54.8 %, respectively, and the in vitro digestible dry matter (IVDDM) yields were 44.4%, 73.7%, and 59.6 %, respectively; therefore, the TDN yield of the corn was 13 % significantly higher than that of the kenaf (p<0.05). The TDN yields of the kenaf, corn, and sorghum ${\times}$ sudangrass hybrid were 12,472 kg/ha, 14,350 kg/ha, and 11,001 kg/ha, respectively. Among the three crops, the content of neutral detergent fiber (NDF) and acid detergent fiber (ADF) were highest in the kenaf. This study shows that the kenaf had a good forage productivity but a low forage quality.

Objectives: The existing reductionist approach has not reached complete understanding of the cause of schizophrenia. The objective of this study was to investigate yin-yang and five-element characteristics reflected on four time pillars of birth of patients with schizophrenia through comparison with the general population in the perspective of consilience-based holistic approach. Methods: This study was conducted using a random sequential recruitment method for the general population and individuals with schizophrenia aged 18 to 64 based on the exact date and time of birth using structured questionnaires. Relative positional relations of yin-yang and five-element with day master were primarily examined. In addition, the strength of day master with a score range of 0∼100 points was assessed through operational score allocation. Results: Of 591 participants, 576 (346: general population, 230: individuals with schizophrenia) were analyzed. Between-group analyses showed no significant difference in the distribution of types of day master (χ2=10.41, df=9, p=0.318). However, significant between-group differences were shown in the distribution of the strength of day master (t=2.14, p=0.032) and frequency of restraining month branch (χ2=5.23, df=1, p=0.022). In logistic regression analysis, 10-point increase on the strength of day master decreased the probability of onset of schizophrenia over the age of 30 by 29.6% (p=0.002; 95% confidence interval, 0.566∼0.876). Conclusions: Findings in this study suggest that four time pillars of birth might be associated with schizophrenia through yin-yang and five-element theory and synchronicity principle, implicating the plausibility of consilience-based holistic approach in the determination of risk factors or cause of schizophrenia.

본 연구에서는 국내 콩 산업의 경쟁력 제고를 위해 국내 콩품종을 간편하고 신속하게 판별을 할 수 있는 기술을 개발하였다. 공우성(Co-dominant)인 STS 마커는 RCR기반으로 한 agarose gel에서 쉽게 확인이 가능한 장점이 있어 대량의 유전자원 분석 및 품종판별에 효율적으로 사용 가능하다. 본 연구에서 MF technique을 이용하여 우리나라 대표품종인 황금콩의 Genomic DNA library를 작성하고 이를 해독한 염기서열 정보로부터 STS-CAPS 마커를 개발하여 국내 콩 품종판별에 적용한 결과를 요약하면 다음과 같다.1. 선발된 총 1440개의 클론 중에서 700 bp 이상인 887개의 콜로니에 대해 염기서열 분석을 하였다. 분석된 클론의 염기서열 정보를 이용하여 총 143쌍의 STS primer를 제작하고, 황금콩에서 단일밴드로 증폭되는 101쌍의 primer를 1차 선발하였다.2. 선발된 101쌍의 primer를 국내 주요 14품종에 적용하여, PCR 증폭 후 AluI, HaeIII 등 7종의 제한효소를 처리, 2% agarose gel에서 전기영동 한 후 품종 간 다형성을 확인하였다. 14개 주요 보급 콩 품종에 대해서 다형성 분석을 통해 총 18쌍의 STS primer를 선발하였다. 3. 콩 품종판별을 위하여 선발한 18개 STS-CAPS 조합(51개 조합)의 총 대립인자 수는 147개였으며, 대립인자 수의 범위는 2-6개이었고, 평균 대립인자 수는 2.9 였다. 분석에 사용한 51개의 STS-CAPS조합의 PIC value는 0.02-0.74 의 범위였으며 평균 PIC value는0.40이었다. 4. 110개 한국 육성 품종을 대상으로 단계별(14단계)로 품종판별을 하였다. 110 개의 품종 중 동일한 패턴을 보인 4개의 품종(진품콩과 진품콩 2호 및 소원콩과 신강콩) 을 제외하고 106(96.4%) 품종이 판별되었다. Soybean is one of the most widely planted crops supplying oil and edible bean. Soybean has a complicated genome due to at least two rounds of polyploidization. Although there are several types of molecular markers available for soybean genotyping, agarose gel-based molecular markers for this purpose are not sufficient. The objective of this study was to develop STS markers that can discriminate Korean soybean cultivars using agarose gels. We employed methylation filtering (MF) technique for constructing a genomic DNA library of “HwangKeum” and selected 1,440 colonies. Of the 1,440 colonies, 887 colonies which had more than 700 bp of insert DNA were sequenced. A total of 143 STS primer sets were designed from sequencing data of selected colonies. One hundred one STS primer sets showed unique band in 14 Korean soybean cultivars and digested with 7 restriction enzymes including Hinf I. Among them, 18 STS primer sets showed polymorphic bands. We developed 51 marker combinations and selected 14 marker combinations, which were used to discriminate 110 Korean soybean cultivars. As the results, 106 cultivars (96.4%) were discriminated by using agarose gel-based markers. Therefore, STS-CAPS markers could be useful to discriminate soybean cultivars and identify soybean genotypes.
