This study was conducted to investigate the involvement of flower abnormality and S-adenosyl-L-homocysteine hydrolase (SAHH), which is one of the key enzyme in the maintenance of methylation. Plants exposed to high temperature (HT) and long day (LD) condition from 14-27days after short day (SD) produced abnormal flower, having numbers of ray florets. Numbers of ray florets were increased more than 2 folds by HT of $35/20^{\circ}C$ and LD of 14 hour comparing those of $25/20^{\circ}C$ (12 h/12 h). Full-length cDNA clone of S-adenosyl-L-homocysteine hydrolase (DgSAHH) in spray chrysanthemum 'Lerbin' contained an 1455 bp open reading frame coding for 485 amino acids. It showed highly conserved coding sequences among the different plant species with over 90% homology. DgSAHH expression was decreased in abnormal flower inducing treatment of HT and LD, while DgSAHH transcripts accumulated in flower bud of non abnormality inducing condition. This result implicate that DgSAHH expression is affected by temperature and photoperiod during flower development and suppression of DgSAHH is a one of the cause of abnormal flower under HT and LD condition.

Background: Benign teratoma is mostly asymptomatic, but this tumor rarely ruptures into the adjacent structure such as the pleural space, pericardium, lung parenchyma or tracheobronchial tree. Thus, it is important to differentiate ruptured teratoma from unruptured teratoma. This study evaluated the difference between ruptured and unruptured benign teratoma. Material and Method: Twenty-four cases of surgically resected benign teratomas were reviewed retrospectively. The clinical symptoms, chest CT findings and operative findings of the ruptured teratoma were compared with those of the unruptured teratoma. Especially, the tumor size, wall thickness, location of the mass, internal septation, homogeneity, calcification and ancillary findings were evaluated on CT. Result: Of the 24 patients, 7 patients were diagnosed with ruptured teratoma. Severe symptoms were more commonly found for ruptured teratoma than for unruptured teratoma. The ruptured teratoma had a tendency to display calcification and such ancillary findings as collapse or consolidation of the lung parenchyma. For the ruptured teratoma, the resection was performed by sternotomy or thoracotomy, and more lung resection was included. Conclusion: Calcification within the mass and changes in the lung parenchyma on the preoperative CT findings can be diagnostic signs of a ruptured teratoma. The demonstration of ruptured teratoma is important not only for making the early diagnosis, but also for the surgical planning.

Deformed vertebrae by cold shock in Rhynchocypris oxycephalus were discovered. Deformity was externally noticed in the caudal penducle region of R. oxycephalus. Radiographic and histologic investigation confirmed the deformity. Especially, histological investigations provided the fact that extensive fusion between neighbouring vertebrae is caused by removal of endogeneous mineralized tissue. Deformed vertebrae appeared suggesting the direct evidence of vertebral fusion had arisen internally by cold shock in this species.

Sixteen-day-old baby with severe Ebstein anomaly underwent emergency operation to relieve progressive hypoxia and congestive heart failure. Operative findings showed huge right atrium and atrialized right ventricle (aRV) with very small functional RV by distal displacemcent of tricuspid valve mechanism. We elected to perform modified Starness operation because biventricular repair was deemed unattainable. After pulmonary and tricuspid valves were primarily closed, aRV was obliterated with multiple sutures from RV apex to the base. Then a PTFE (Gore-Tex, USA) vascular graft was interposed between innominate artery and main pulmonary artery for systemic to pulmonary shunt. The patient was discharged uneventfully, and received bi-directional cavopulmonary shunt 6 months later.

분사된 연료의 미립화(atomization), 증발(evaporation), 그리고 혼합기형성과정(mixture formation process)이 디젤엔진의 착화 및 연소특성에 영향을 미치기 때문에, 디젤엔진 내에 분사된 연료의 구조해석으로부터 일련의 과정, 즉 고압분사, 분열(breakup), 미립화, 그리고 주위기체의 난류 도입(entrainment)에 관한 연구$^{1-3)}$는 꾸준히 행해져왔다. 본 연구는 증발디젤분무의 구조해석으로부터 디젤충돌분무의 혼합기형성과정을 조사한다. 주위기체의 밀도는 실험변수로서 선택하였고, $5.0kg/m^3$에서 $12.3kg/m^3$까지 변화시켰다. 그리고 소형고속디젤엔진에 있어서 연료분사초기의 상태의 고온 고압 설정이 가능한 정적용기를 사용했다. 주위 온도와 연료분사압력은 각각 700K 및 72MPa로 일정하게 유지했다. 충동증발분무의 액상과 기상의 이미지는 엑시플렉스형광법으로 동시 계측하였다. 실험결과로서 주위기체의 밀도가 높을수록 충돌분무의 선단도 달거리가 주위기체의 항력으로 인하여 감소하였다.

Ebstein's anomaly is a complex congenital defect of the tricuspid valve and right ventricle. Various surgical methods to repair the regurgitant tricuspid valve have been reported, and most of them depend on monocuspidalization with using the anterior leaflet. We report here on our first experience with Ebstein's anomaly in a 31-year-old female patient who underwent cone reconstruction of the tricuspid valve with using three leaflets.
