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.

연쇄알구균에 의한 급성 인후염 후 발생한 반응성 관절염은 급성 류마티스열의 개정된 진단기준을 충족하지 못하면서, 지속적 혹은 재발성의 비이동성 관절염과 발열, 홍반성 결절, 일시적 간기능 이상 등을 보이면서 심장염과 무도증을 드물게 동반하는 질환이다. 따라서, 발열을 동반한 급성 관절염 환자에서 감별해야 할 질환 중의 하나이며, 심근염 예방을 위한 페니실린 요법의 적응증 및 기간에 대해서는 아직 이론이 많은 상황으로, 보다 광범위한 연구가 필요하다. 저자들은 연쇄알구균에 의한 급성 인후염 1주 후에 발생한 하지의 다발성 비이동성 관절염과 함께 결절홍반 및 일시적 간기능 이상을 보인 환자에서 PSRA로 진단하고 비스테로이드성 항염증제 및 스테로이드로 성공적인 치료를 하였기에 이를 문헌 고찰과 함께 보고하는 바이다. Poststreptococcal reactive arthritis (PSRA) is associated with recent streptococcal infections. However, PSRA is distinct from acute rheumatic fever by its clinical manifestations: non-migrating arthritis, erythema nodosum or erythema multiforme, and transient elevation of serum transaminases. We experienced a 33-year-old man who presented with fever, arthritis of both knees and ankles, and erythema nodosums on extensor surfaces of lower legs which developed 6 days after the onset of pharyngitis symptoms. Blood and urine cultures were negative. Throat culture was negative for group A β-hemolytic streptococcus. The ASO titers increased up to 2080 IU/mL in sequential monitoring. The result of bone scan was compatible to arthritis of both knees and ankles. There were no signs or symptom of carditis. He showed clinical improvement with anti-inflammatory drugs (naproxen 1,000 mg/day and prednisolone 7.5 mg/d). PSRA should be included in the differential diagnosis of patients presenting with arthritis combined with fever.

연구 목적 : 본 연구의 목적은 입원치료후 퇴원한 품행장애 환자들의 예후와 가족들의 정신과 입원치료의 효능에 대한 인식도를 알아보고 예후에 영향을 미칠 수 있는 요인을 알아보기 위한 것이다. 방법 : 품행장애의 진단 하에 7일 이상 입원치료를 받았으며 퇴원 후 6개월이 경과된 300명 중 전화 추적이 가능하였던 96명에서 퇴원 후 문제행동, 가족관계, 가족들의 인식도를 조사하였으며 이와 관련된 요인을 알아보았다. 결과 : 퇴원 후 문제행동의 양상은 입원전보다 호전된 경우가 90%이었으며 더 심해진 경우는 2%이었으며 8%는 변화가 없었다. 퇴원 후 가족관계는 보다 좋아진 경우가 70%, 나빠진 경우가 2%, 별 차이가 없는 경우가 28%이었다. 병원치료의 효율성에 대한 가족들의 인식도는 도움이 되었다는 경우가 57%, 해가 되었다는 경우가 6%, 그저 그렇다가 37%이었다. 퇴원 후 문제행동, 가족관계, 가족들의 입원치료에 대한 인식도 등 세 가지 항목이 모두 양호하다고 답변한 대상을 양호군으로 설정하고 그 외의 대상을 대조군으로 하여 양군의 특성의 차이를 비교하였을 때 양호군의 연령이 유의하게 낮았으며 가족 형태의 문제가 있었고 MMPI하위척도 중 남성성 -여성성 척도 점수가 유의하게 높았다. 결론 : 비록 본 연구는 여러 제한점이 내포되어 있음에도 불구하고, 정신과 입원치료를 받았던 청소년의 행동이 대부분은 호전된다는 것을 시사하여 품행장애에서의 정신과적 치료에 상당히 고무적인 결과를 나타내었으며 추후 대상자와 치료프로그램의 다양성을 통제한 연구를 지속하는 것이 필요할 것으로 생각되었다. 중심 단어 : 품행장애ㆍ청소년ㆍ예후ㆍ입원치료. Objectives : The major goal of this study was to investigate the treatment outcome of psychiatric treatment in inpatients with conduct disorder and to elucidate factors affecting its prognosis. Methods : We reviewed the medical records of 300 inpatients with conduct disorder who had been treated with a specialized adolescent treatment program. Follow-up structured telephone interview had been performed in 96 patients. Results : 1) At the point of follow-up, 90% of the patients were improved in behavioral patterns, 2% of the patients were worse, and 8% of the patients were unchanged. 2) Intrafamilial relationship was improved in 70% of the patients, worse in 2%, and unchanged in 28%, 3) Fiftyseven percent of families thought to be helped by psychiatric inpatient treatment, 6% replied to be harmed, and 37% thought not to be helpful. 4) Comparing the good prognosis group who were all better in behavioral patterns, intrafamilial relationship, and efficacy of treatment with the rest of subjects, the good prognosis group was significantly younger and had more history of problems in familial structure. Conclusion : Although the present study had some meterological limits, the promising positive results in the outcome of inpatients with conduct disorder encourages further more sophisticated investigations in this problematic psychiatric conditions. KEY WORDS : Conduct disorderㆍAdolescentㆍTreatment outcomeㆍInpatient treatment.

배추 시스테인 단백질 분해 효소 억제 유전자 BCPI-1의 발현과 종자 발아 및 유묘 생장과의 연관성

Phytocystatins are protein inhibitors of cysteine proteinases of the papain family that have been identified in both monocot and dicot plants. A cDNA encoding a phytocystatin, BCPI-1 (Brassica Cysteine Proteinase Inhibitor-1) has been isolated from Chinese cabbage (Brassica campestris L. ssp. pekinensis) flower buds. Here, we tested whether BCPI-1 transcription is regulated by hormones, and could be involved in regulating cysteine proteinases during and after germination. BCPI-1 was sensitive to exogenous GA_(3) and ABA, which are important factors controlling seed germination, suggesting that the expression of BCPI-1 is hormonally regulated. We introduced a recombinant plasmid containing the full-length BCPI-1 cDNA under the control of cauliflower mosaic virus 35S promoter into rice embryogenic calli using the particle delivery method, and regenerated a number of transgenic rice plants. Constitutively over-expressed BCPI-1 caused changes in overall plant growth and development, including reduced germination and seedling growth. These data support the role of the BCPI-1 in the regulation of endogenous proteinases during both seed germination and subsequent seedling development. Phylocystatins은 papain계열의 cysteine 단백질 분해 효소 활성을 특이적으로 억제하는 억제자로 다양한 식물 종으로부터 분리되었다. 본고에서는, 배추 화아 cDNA library로부터 분리된 phytocystatin인 BCPI-1(Brassica Cysteine Proteinase Inhibitor-1)의 생체 내 기능에 대해 연구하였다. 먼저, BCPI-1 전사체는 발아 조절에 중요한 영향을 미치는 GA₃와 ABA에 의해 예민하게 증가, 혹은 감소되는 반응을 보임으로써, BCPI-1이 식물 호르몬의 영향을 받으며, 특히 발아나 유묘의 생장 조절에 관련이 있음을 알 수 있었다. Particle bombardment 방법을 통하여 BCPI-1을 벼의 배 형성 세포 내에 도입, 재분화 시켜 형질 전환 벼를 생성하였다. CaMV 35S promoter의 조절에 의해 지속적인 BCPI-1 발현을 보이는 형질 전환 벼의 경우, 발아와 유묘 생장이 현저히 지연되었다. 위의 결과들을 바탕으로, BCPI-1이 식물체 내에서 생성되는 cysteine 계열의 단밸질 분해 효소 활성을 조절하여 종자의 발아와 유묘의 생장에 영향을 미치는 것으로 추측한다.

Objectives : Pneumoconisis and noise-induced hearing loss (NIHL) have been reported as main occupational diseases by the Special Health Examination. The Industrial Accident Compensation Insurance has reported various work-related diseases, however, these two diseases occupied almost a half of compensated cases. Therefore, it was not well known about the status of occupational diseases other than pneumoconiosis, NIHL, and cardio-cerebrovascular accident (CVA). This study was conducted to analyze claimed cases as an occupational disease, that was requested to the Korea Industrial Safety and Health Agency (KOSHA). Methods : The local office of the Korea Labor Welfare Corporation (KLWC) has asked the KOSHA for confirmation of claimed cases as an occupational disease. We analyzed 379 cases requested from KLWC, the Ministry of Labor, employers, unions and occupational health agencies from 1992 to 1999. Results : Male was 80.7 % of the requested cases. Their mean age was 42 years old and 75.5 % of them were more than 35 years old. The requested cases were increased rapidly from 25 cases in 1992 to 108 cases in 1999 and the accept rate was 50.7 %. The majority of requested cases were respiratory diseases(22.4%), cancers(18.5%), Neuropsychiatric problems(14.5%), and musculoskeletal problems(13.5%). The accept rate was high in reproductive, respiratory, musculoskeletal and digestive disorders and low in neuropsychiatric, renal and otologic problems and occupational cancers. 73.6% of them were caused by chemical agents, especially 28.5 % were by organic solvents. 67% of them were clinically confirmed at university hospitals. A half of the cases were from KyongIn area, even the request came from the whole country. Conclusions : A claim was common in workers whose age was over 35 years old and exposure history was over 10 years. The respiratory diseases and neuropsychiatric disorders were still main problems in occupational health and occupational cancers was increasing even though its accept rate was not high yet.

Yang, Chae Eun,Park, Kwang Hyun,Lee, Dong Won,Lew, Dae Hyun,Song, Seung Yong Korean Society of Plastic and Reconstructive Surge 2019 Archives of Plastic Surgery Vol.46 No.1

Background Acellular dermal matrices (ADMs) have recently become widely used in breast reconstruction, but the correlation between the final expander volume and the surface area of the ADM is not well understood. In this study, the expansion of the surface area of ADM and the expander volume was studied retrospectively in cases of acellular dermis-assisted tissue expander breast reconstruction. Methods Twenty cases of immediate breast reconstruction using an ADM-assisted tissue expander from January 2015 to December 2015 were evaluated. In all 20 cases, CGCryoDerm was used as the matrix, with a thickness of 1-3 mm. No slit incisions were made. Finally, the proportional increase in the area of the fully expanded ADM was compared to that of the tissue expander volume. Results The proportional increase in the ADM surface area was calculated to be from 1.1 to 2.46, with a mean value of 1.7. Additionally, under the assumption that the expander had a spherical shape, the increase in its radius (the cube root of its volume) was assessed. The range of the proportional increase in the expander radius was 1.1 to 2.24, with a mean value of 1.66. The proportional increase in the radius of the expanded ADM surface area ranged from 1.04 to 1.34, with a mean ratio of 1.28. Conclusions The results of this study confirmed that the ADM expanded when the tissue expander was inflated. However, the ADM expanded to a lesser extent than the tissue expander, indicating that the muscle and other tissues expanded more than the ADM when the tissue expander was inflated.
