A specific disease syndrome, which led to massive mortality on larve of rockfish(Sebastes schlegeli) in marine hatcheries at Chungnam area during the period 1995~1996 was studied. The causative agent isolated from the diseased or dead larvae was identified as Vibrio ordalii on the basis of biochemical and biological characteristics. In the experimental challenges aganist 0 and 1 summer fish conducted at two different temperatures as $18^{\circ}C$ and $25^{\circ}C$, Vibrio ordalii showed higher virulence to no summer fish at $18^{\circ}C$ than 1-summer fish at $25^{\circ}C$. These results were consistent to field data obtained during epizootic outbreaks in the farms. Moribund and died larvae presented telangiectasis of secondary gill lamella and brain, dissecting of respiratory epithelium, atrophy of hepatic cells and necrosis of kidney associated with the presence of the bacteria. But the digestive tissue of these fish showed no significant change.

A 45-year-old man underwent heart transplantation due to dilated cardiomyopathy. Cyclosporine, 2 mg/kg per day, was intravenously givell postoperatively. As central neurotoxicity signs that were included pin-point pupil, no light reflex, coma, were presented at 8 postoperative hours, cyclosporine was decreased to 1 mg/kg er day. At that time the cyclosporine level was 345 $\mu\textrm{g}$/L, the serum creatinine level was 1.8mg/dl and the serum magnesium level was within normal limit. He awaked at 31 postoperative hours and all sign of cyclosporine-induced central neurotoxicity was resolved after postoperative days. He was discharged without sequale at postoperative day 28.

Concentration of quercetin and soluble tannin in Houttuynia cordata were determined at different growth stages as well as plant parts and application amounts of compost. Both contents of quercetin and tannin at growth stages were decreased before flowering time but slightly increased after flowering. The both contents of components in Houttuynia cordata collected on April 20 were shown to be markedly increased compared to those collected in May or June. The contents of quercetin and tannin at different organs were the highest in the flower. In the experiment of application amounts of compost, as application amounts is increased, fresh weight of aerial part was increased but the contents of quercetin and tannin were decreased. The contents of quercetin and tannin were the highest with 0.67% and 2.3%, respectively, in the compost non-treatment.

Hepatopulmonary syndrome is a triad that includes: hepatic dysfunction, intrapulmonary vascular dilatation and abnormal arterial oxygenation. The incidence of intrapulmonary vascular dilatations, in adults with end-stage liver disease, has been reported to be 13% to 47%, however the incidence in children is unclear and the cases in Korean children have never been reported. The hepatopulmonary syndrome may occur as a result of chronic liver disease following nonalcoholic steatohepatitis in children with hypothalamic or pituitary dysfunction. We report a case of hepatopulmonary syndrome in a 13-year-old child who had rapidly progressive liver dysfunction secondary to panhypopituitarism after craniopharyngioma resection. Careful monitoring and treatment of endocrine abnormalities and metabolic status, as well as liver function, are required in all children undergoing pituitary tumor resection.

We report three patients with pulmonary hypertension in Takayasu's arteritis, who showed long-term favorable response, clinically and hemodynamically, to the nitric oxide donor, molsidomine. In these patients, the inhaled nitric oxide was effective in reducing pulmonary artery pressure (PAP) and pulmonary vascular resistance (PVR) as was shown in the acute vasodilator response test using the invasive hemodynamic monitoring. Molsidomine (single oral dose of 4 mg) was also effective in reducing PAP and PVR in the acute test, but nifedipine was not. With 4 mg of molsidomine three times daily, their dyspnea, exercise capacity and hemodynamic parameters were improved. These favorable responses have lasted during the 1st and 3rd month follow-up in all patients.

Pulmonary lymphangiomatosis is a very rare pulmonary lesion with an aggressive potential that occurs mainly in newborns, infants and young children of both sexes. It is characterized by pulmonary abnormalities of lymphatic system, showing an increased number of complex anastomosing lymphatic channels in the pleura, in the subpleural interlobular septa, and along the bronchovascular lymphatic route and uniformly fatal. We report a case of lymphangiomatosis behaving like lymphangioleiomyomatosis in a 26-year-old woman.

Biodegradable polymeric stents have been issued to replace the existing non-degradable metal stents due to relatively improved biocompatibility and low side effects. Fundamentally, all the stents must possess the desired mechanism strength, especially, compression or radial force to maintain the diameters of expanded vessels. Therefore, this study suggests a helical structure and focused on the relation between the lateral compression and structural factors, Unlike a cylindrical model, the radial force of the helical model is proportional to the thickness and the length to the power of one, whereas the diameter to the power of 1.6. The function obtained from these results might provide the fundamental information to design and prepare the stem for clinical applications.

배경: 우심실 유출로 재건술후에는 폐동맥판막부전이 우심실기능에 나쁜 영향을 미친다. 이를 막기 위해 여러 재료로 판막을 제조하여 사용하는데 가피 형성이 적은 막형 ePTEE(expanded polytetrafluoroethylene, Goretex) 단엽판막의 효과를 알아보고자 연구를 시행하였다. 대상 및 방법; 1996년 3월부터 1997년 2월까지 우심실유출로 재건술을 시행받고 수술 1일까지 우심실 압력을 측정할 수 있었던 47명중 막형 Goretex단엽판막을 사용한 환자(비교군) 19명, 사용하지 않은 환자(대조군) 28명에서 단엽판막의 유용성을 조사하였다. 두 군간에는 나이, 체중 그리고 McGoon ratio 등에는 통계학적 차이가 없었다.(p>0.05) 이전의 수술은 대조군에서 19번, 비교군에서 22번을 시행하였다. 우심실 유출로에 대한 수술은 대조군에서 REV수술 2예, 우심실폐동맥 연결수술 8예, 우심실 유출로 재개건술 2예, 우심실 유출로에 대한 수술은 대조군에서 16예였으며, 비교군에서는 REV 수술 5예, Rastelli 씨 수술 6예, 재우심실 유출로 재건술 5예, 그리고 우심실 재건술 3예였다. 결과: 대동맥 차단 시간이나 총심폐순환시간에는 두군간의 차이는 없었다. 또한 수술직후와 수술후 1일째 측정한 우심실 압력 및 좌심방압력의 차이도 두군간에는 차이가 없었으며 수술후 7일째 시행한 심에코도 결과 ejection fraction., 우심실/ 좌심실 압력비 , 그리고 우심실 유출로의 압력차, 강심제 투여일수, 호흡기 사용 기간 등에서도 두군간의 차이는 없었으나 흉관 삽입기간이 비교군에서 의미있게 짧았다. 추적 조사 기간 중 비교군 1예에서 사망을 하였으나. Goretex 단엽판막에 의한 것은 아니였으며 심초음파검사상 우심실 유출로 압력차이나 재수술은 두군간에 차이는 없었으나 폐동맥 폐쇄부전은 비교군에서 의미 있게 낮은 것을 보이고 있다. 결론; 막형 Goretex 단엽판막의 조기성적은 우수하였으며 폐동맥 폐쇄분전의 정도를 적게 하는 효과를 보이나 앞으로 이들이 성장함에 따라 우심실 유출로에 폐쇄를 일으키는지는 계속적인 추적관찰이 요구된다.

Esophageal perforation is relatively uncommon but it often cause fatal if not properly treated, and it is associated with high morbidity and mortality. We report here on two cases of esophageal perforation caused by Boerhaave syndrome or pneumatic dilatation for treating achalasia. The patients were successfully treated with thoracoscopic primary repair and esophagomyotomy.

Kawasaki disease (KD) is an acute febrile mucocutaneous lymph node syndrome that commonly presents with stable hemodynamic status during the acute phase. An 8-year-old boy initially presented with severe hypotension and acute kidney injury. He was placed in the intensive care unit and was diagnosed with KD. Observed clinical features were defined as KD shock syndrome. His coronary artery was dilated during the subacute phase. Furthermore, he was given anti-hypertensive medications, owing to hypertension as an unusual complication of KD. We knew the importance of monitoring for blood pressure considering vasculitis as an aspect of the main pathogenesis of KD.
