Owing to frequent heavy rain due to abnormal weather, the occurrence of pepper anthracnose has recently increased, which affects the supply and demand of pepper. As a result, the price of red pepper powder in 2011, for example, increased three times compared to the average year. Although anthracnose of pepper plants has been controlled by fungicides until now, it is important to develop new resistant cultivars because of the reduction of the labor force in rural area and occurrence of new anthracnose strains resistant to fungicides. National Institute of Horticultural and Herbal Science developed two pepper lines, ‘Wonye 100005’ and ‘Wonye 100006’ that are resistant to pepper anthracnose. These lines were developed by continuous selection of progenies from a cross between ‘Wonye AR1’, which were developed from interspecific hybridization and ‘TF68’. The anthracnose resistance level of the two lines was higher than that of commercial cultivars and similar to check varieties showing highest level of anthracnose resistance.

Injury to peripheral nerve somtimes lead to neuropathic pain. Nitric oxide(NO) is increased in the dorsal root ganglia (DRG) of neuropathic pain models, and L-NAME, a nitric oxide synthase (NOS) inhibitor, reduces neuropathic pain. However, it is not known that underlying mechanism of NO involvement in development and maintanence of neuropathic pain. It was found that there were three NOS isoforms-nNOS, eNOS, and iNOS. It is also necessary to investigate NOS isoforms in neuropathic pain. The aim of this study is to investigate NOS isoforms and NADPH-diaphorase expressions and underlying mechanism of NO involvement in neuropathic pain. The 5^th lambar (L5) DRG were obtaind after tight ligation of L5 an L6 spinal nerves for 7 days. Toluidine blue stain, immunohistochemistry for nNOS, eNOS, and iNOS, and NADPH-diaphorase histochemistry were performed. All specimens were observed under light microscope. nNOS expression was increased significantly in the cytoplasm of the DRG of ligated side at 7 day post-ligation (7D PL). eNOS expression was also increased in the blood vessel, a few neurons or satellite cells, and cell membrane of Schwann cells in the DRG of ligated side at 7D PL. iNOS expression was increased in a few blood vessels and cytoplasm of small neurons in the DRG of ligated side at 7D PL. NADPH-diaphorase expression was increased significantly in the neurons of the DRG of ligate side at 7D PL, but NADPH-diaphorase expressions were weak or absent in the blood vessel and Schwann cell in the contralateral DRG and the DRG of ligated side at 7D PL. It is suggested that NOS isoforms may be closely related to development and mantanence of neuropathic pain in order of nNOS>eNOS>iNOS.

조은정,양원식 대한치과교정학회 1996 대한치과교정학회지 Vol.26 No.1

본 연구는 골격성 Ⅲ급 부정교합 환자에서 상악골 전방이동수술과 하악골 후방이동수술을 동시에 시행하였을 때 경,연조직 측모 및 연조직 후경의 변화를 관찰하고 경,연조직 변화의 상관성과 그 비율을 산출하여 교정-악교정 수술 복합 치료 계획의 수립과 결과의 예측에 이용하고자 하였다. 서울대학교병원 치과진료부 교정과에 내원하여 상, 하악골의 수직적 골격 부조화는 경미하고 전후방적 골격 부조화가 심한 골격성 Ⅲ급 부정교합으로 진단되어 술전 교정치료를 받고 1990년 7월부터 1995년 4월 중에 Le Fort I 골절 단술 또는 Le Fort Ⅱ골절단술로 상악골을 전방이동시키는 동시에 시상분할 골절단술로 하악골을 후방이동시킨 성인 환자 25명(남자 13명, 여자 12명)을 대상으로 수술전, 후 측모두부방사선사진을 계측, 분석하여 다음과 같은 결과를 얻었다. 1. 상악골의 전방이동에 따른 상순부 연조직의 수평적 변화는 Stms를 제외하면 상관성이 높았으며 A point의 전방이동에 따라 Sn, SLS, LS 는 각각 71%,67% 37%의 비율로 전방이동하였다. 2. 하악골의 후방이동에 따른 하순부 연조직의 수평적 변화는 상관성이 상당히 높았으며 ID, B Point,Pog, Gn의 후방 이동에 따라 LI, ILS, Pog', Gn'은 각각 84%, 107%, 96%, 97%의 비율로 후방이동하였다. 3. 하악골의 후방이동에 따라 SLS, LS, Stm, LI 는 중등도의 산관성을 가지며 하방이동하였다. 4. 경조직의 전후안면고경비율과 연조직의 상,하안면고경은 수술전후 유의한 차이가 없었으나 수술후 Stm의 하방이동으로 하순고경에 대한 상순고경의 비율은 유의성있게 증가하였다(p<0.001). 5. 연조직 후경은 수술후 LI-LIH에서는 증가하고 LS-LSH에서는 감소하였으며 LS-LSH의 수술후 변화량과 수술전 후경은 역상관관계를 나타내었다(p<0.001). The purpose of this study was to evaluate the amount and interrelationship of the soft and hard tissue changes after simultaneous maxillary advancement and mandibular setback surgery in skeletal Class Ⅲ malocclusion. The sample consisted of 25 adult patients(13 males and 12 females) who had severe anteroposterior skeletal discrepancy. These patients had received presurgical orthodontic treatment and surgical treatment which consisted of simultaneous Le Fort I or Le Fort Ⅱ osteotomy and bilateral sagittal split ramus osteotomy. The presurgical and postsurgical lateral cephalograms were evaluated. The computerized statistical analysis was carried out with SPSS/PC program. The results were as follows: 1. The correlation of maxillary hard and soft tissue horizontal changes were high and the rations for soft tissue to A point were 71% at Sn, 67% at SLS and 37% at LS. 2. The correlation of mandibular hard and soft tissue horizontal changes were very high and the rations were 84% at LI, 107% AT ILS, 96% at Pog' and 97% at Gn'. 3. The correlation of mandibular hard tissue horizontal changes and soft tissue vertical changes were moderate. 4. The upper to lower lip length were increased(P<0.01). 5. The soft tissue thickness were decreased in upper lip and increased in lower lip(p<0.001). The postsurgical changes were reversely correlated with initial thickness in upper lip.

오양효,윤소겸,공은진,김민정,김영부,박영민 대한감염학회 1995 감염 Vol.27 No.5

목 적 : 이미 보고되어 있는 파아지들의 경우, 일반적인 형태, 숙주역과 몇 가지의 성질만 연구되어 있으므로 보다 상세한 특성에 대한 연구가 필요한 상태이다. 본 연구에서는 해양으로부터 분리한 V. vulnificus를 숙주균으로 하여 투명한 용균반을 형성하는 파아지를 분리해 낸 다음, 분리된 V. vulnificus 파아지의 특징을 연구하고자하였다. 방 법 : V. vulnificus 를 숙주균으로 하여 해산물로부터, 숙주균에 특이적인 파아지를 분리하고, 농축 정제과정을 거쳐 파이지입자를 순수분리하였다. 파아지의 형태를 전자현미경으로 관찰하였으며, 분리된 파아지의 숙주특이성을 조사하고, 파아지 입자의 물리적 특성을 검토하기 위해, 온도 안정성시험, pH 안정성 시험을 실시하였다. 파아지의 흡착율, 파아지의 흡착율에 미치는 무기염 이온의 영향, 온도의 영향과 pH의 영향을 관찰하였다. 파이지의 일단증식곡선을 구하였으며 토끼 면역과 교차 중화 시험, 파아지 핵산의 특성, 구조단백질의 특성을 조사하였다. 결 과 : 전자현미경관찰결과 본 연구에서 분리한 파아지는 두부와 미부를 가지는 형태로 미부에 꼬리판과 꼬리섬유를 가지고 있었다. 파아지의 물리적성질시험 결과 파아지는 50℃이하의 온도에서 안정하였으며 중성pH영역에서 안정하고 산성과 알칼리 영역에서는 활성을 잃었으며 자외선에는 35초 조사에 50% 정도 불활성화 되었다. 파아지는 약 65%의 흡착율을 나타내었으며 흡착에 ??, ??을 요구하였다. 파아지입자가 안정한 온도와 pH영역에서는 흡착에 영향을 받지 않았으며 일단증식시험 결과 108 PHU/ml의 파아지 입자를 생산하였다. 정제한 파아지를 항원으로 하여 토끼에 면역한 항혈청에 파아지가 중화되었으며 파아지 핵산은 이중나선 DNA였다. 파아지의 구조단백질은 SDS-PAGE polyacrylamide gel 전기영동 결과 2개의 밴드를 나타내었다. 그리고 Western blotting 결과 파아지의 전기영동 결과와 동일한 위치의 밴드에서 항원성을 나타내었다. 결 론 : 인체병원균으로 중요성이 인식되고 있는 V. vulnificus는 해산물의 위생과 국민건강에 직접적인 영향을 미칠 수 있는 세균으로 이에 대한 활발한 연구가 요구되는 실정이다. 파아지의 분리율은 숙주균의 분리율에 의존하므로 숙주균의 해수내 분포에 영향을 미친다고 추측되며, 파아지는 숙주균에 감염되어 숙주균을 용균시키므로 숙주균의 개체수를 조절하여 생태학적 측면에서 중요한 기능을 담당하는 것으로 여겨진다. Background : Vibrio vulnificus causes severe wound infection and life-threatening septicemia. In this study we present the characteristics of V. vulnificus bacteriophage and the basis of pathogenicity study of V. vulnificus related on bacteriophage. Methods : We isolated bacteriophage for V.vulnificus from marine products and examined its physiological and biochemical characteristics, and the ultrastructure by electron microscopy (TEM,SEM). And also, we investigated host ranges, temperature stability, pH stability, inactivation by UV irradiation, DNA isolation and analysis and structural protein analysis of the bacteriophage. Results : The adsorption rate of bacteriophage was above 80% and had a little influence at 10-45℃ and pH5-10. Isolated bacteriophage was used to produce antiserum against rabbits and its antigenicity was investigated by cross-neutralization. Western blot analysis showed the capsid protein of bacteriophage had antigenicity. The bacteriophage had double-strand DNA. In restriction analysis, the phage DNA was digested HinfI. The structural protein of phage showed two bands of 34.7kDa and 18.4kDa on SDS-PAGE. Conclusion : The specificity of bacteriophage may be due to the specific binding site that be possessed by host strain surface. Therefore, it seems that virulent bacteriophage controls the number of host strain and then takes a role on natural marine environment.

Few topics in operative and perioperative patient management generate more controversy than that of appropriate fluid and electrolyte therapy. especially, controversy has swirled around colloid vs crystalloid therapy and the composition of administered fluids, agreement among clinicians as to what fluid therapy is appropriate, and in what amount, is rare. This controversy likely will be enhanced by Arieff' s provocative article. He described 11 adults and 2 pediatric patients. All developed fatal postoperative pulmonary edema, seemingly caused solely by excessive postoperative fluid administration. From January 1999 to December 1999, we investigated 24 patients, which were operated by orthognathic surgery, about the intraoperative fluid therapy and the associated effect in orthognathic surgery, which is regarded as one of the major surgery of oral and maxillofacial surgery. First, They were devided into two groups, that is one-jaw surgery and two-jaw surgery, and each groups were devided by intraoperative fluid volume of 8ml/kg/hr. Subjective assesment was collected through use of a series of 3 questionnaries. In each questionnaire, a 5-point Liekert scale was used far assessment of following parameters of recovery from anesthesia: headache, dizziness, drowsiness, nausea/vomiting, thirst. The patient completed questionnaire 1 at 4 hour after surgery, questionnaire 2 was completed at 24 hours after surgery, and questionnaire 3 was completed at 48 hours after surgery. This study demonstrated that appropriated perioperative rehydration decreases postoperative adverse outcomes and improved the patient's perception of the postoperative period.

박정은,임선희,선우양일 동아대학교 기초과학연구소 2000 基礎科學硏究論文集 Vol.17 No.1

본 연구에서는 효모의 돌연변이주를 분리하여 G1/S기에서 세포주기 진행에 관련된 유전자의기작을 이해하기 위해 연구를 수행하였다. 먼저, cos28과 cos46 돌연변이주의 MMS(methylmethane sulfonate)와 HU(hydroxyurea)에 대한 감수성을 조사하였다. 이들 돌연변이주들은 MMS와 HU에 대해서 감수성을 보이므로, S기 checkpoint에 관련되었다고 생각된다. 다음으로 cos28과 cos46 돌연변이를 상보하는 유전자를 클로닝하였고, 서열화하였다. 그리고 클론된 유전자는 데이터 베이스 분석을 통해 조사하였다. cos28 변이주를 상보하는 DNA 단편은 전체 6개의 ORF를 가지며 그 중 기능이 알려진 ORF로는 RPS21B와 LCB3와 MRS3가 있고, 기능이 알려지지 않은 ORF로는 YJL131와 YJL132와 YJL135의 세개를 포함하고 있었다. cos46 유전자는 전체 6개의 ORF를 가지며, 그 중 기능이 알려진 CYP5와 HNT2와 SRB7와 GIC2를 가지고, 기능이 알려지지 않은 ORF로 YDR306, YDR307를 포함하고 있음이 확인되었다. In this study, to understand the mechanisms of genes which related in cell cycle progression at G1/S phase, using the isolated mutants in S. cerevisiae were investigated. First of all, cos28 and cos46 were examined the sensitive to MMS(methylmethane sulfonate) and HU(hydroxyurea). These mutants were showed MMS, HU sensitivities and might be a act at a checkpoint pathway during S phase. These mutants were carried out gene cloning for the gene which were complemented the cos mutants. As a result, the DNA fragments which complement with the cos28 and cos46 mutants, were cloned and sequenced. And then cloned genes were surveyed though data base analysis. Complemented DNA fragment of COS28 contained six ORF which were consisted RPS21B, LCB3, MRS3, YJL131, YJL132, and YJL135. Complemented DNA fragment of COS46 contained six ORF which were consisted CYP5, HNT2, SRB7, GIC2, YDR306 and YDR307.

The Effects of a Social Skills Program on Improving Sociability, and Adaptive Behaviors of Children with Developmental Disabilities. The purpose of this study was to investigate the effects of a social skills program on improving social skills, and adaptive behaviors of children with developmental disabilities. A total of nine children at the Language Therapy Center for children and adolescents in Gwangju Metropolitan City participated in this study with the consent from their parents. The research was conducted following one-group pretest-posttest design, a preexperimental design. A social skills program was implemented once a week with 90 minutes per session for 15 weeks. The effects of the program were evaluated by administering Social Maturity Scale, and Adaptive Behavior Scale before and after the program. The results showed that the scores in social maturity, and adaptive behavior scales, respectively, increased from pretest to posttest. This study concluded with a discussion on the implications of social skill programs for improving social skills, and adaptive behaviors of children with developmental disabilities in the field of social welfare. Implications and suggestion for future studies was discussed.
