  • 2001년 9월 경기도 성남시 분화용 브룬펠지아에서 F. oxysporum에 의한 줄기마름병이 발생하였다. 처음에는 생육이 부진하고 아래 잎부터 누렇게 변색되며, 줄기가 마르고 심한 경우 나무 전체가 말라죽는다. 병든 식물체의 줄기를 잘라보면 줄기 내부의 도관부가 갈색 내지 암갈색으로 변하는 것이 특징이었다. 병원균을 분리하여 형태적·배양적 특징을 조사한 결과 F. oxysporum으로 동정되었으며 병원성 검정 결과 자연상태와 동일한 병징을 확인할 수 있었으므로 이 병을 Fusarium oxysporum에 의한 브룬펠지아 줄기마름병으로 명명할 것을 제안한다.

  • In previous study, we demonstrated tilianin inhibits tumor necrotic factor-${\alpha}$ (TNF-${\alpha}$) induced vascular cell adhesion molecule-1 (VCAM-1) expression in human umbilical vein endothelial cells (HUVEC). In this study, we demonstrate inhibition of the production of atherogenic cytokines and the anti-atherogenic effects of tilianin in Ldlr-/- mice.(omitted)

  • Microvascular free tissue transfer technique is widely accepted for reconstruction of extensive soft tissue defects on the extremities. The system of flap based on the subscapular artery and vein provides the widest ways of composite free flaps. The possible flaps that can be harvested based on this single vascular pedicle include the scapular and parascapular skin flaps, the serratus anterior and latissimus dorsi muscular flaps, the lateral scapular bone flap, the latissimus dorsi-rib flap, and the serratus anterior-rib flap. This combined flap is available to mutiple tissue defects or complex defects because it can incorporated with skin, muscle and bone flaps. A strikig advantage is the independent vascular pedicles of each components, which allow freedom in orientation of each components. So, it can be freely applied to any forms of three demensional defects on the upper and lower extremities. The combination of scapular cutaneous flap and latissimus dorsi musculocutaneous flap can be resurfaced for massive cutaneous defects on the extremities. We report the use of the combined scapular and latissimus dorsi free flap in seven patients to reconstruct massive deefcts on the extremities. There was no flap failure and little complications and disadvantages. The anatomy of this flap is reviewed and the indication and advantages are discussed.

  • 두개내 경막 동정맥루는 모든 두개내 혈관 기형의 약 10%-15%를 차지하는 비정상적인 동정맥 단락이다. 대부분의 두개내 경막동정맥루는 단독형이며, 다른 부위에 여러 경막동정맥루가 있는 경우는 드물다. 여러 경막동정맥루에 대한 대부분의 증례 보고에서는 동기형 동정맥루를 기술하였고, 이시성 경막동정맥루에 대한 보고는 상대적으로 적다. 이에 저자들은 경막 동정맥루의 색전술 후 추적 영상에서 이시성 경막 동정맥루가 발견된 75세 여성의 증례를 보고 하고자 한다.

  • True aneurysm of the carotid artery is relatively rare in comparison with the total number of aneurysms of the arterial system. The threat of rupture and embolization from mural thrombi are indications for treatment even though no symptoms may be present. Resection of the aneurysm and restoration of arterial continuity is the treatment of choice. A case of aneurysm of the Lt. common carotid artery of a 21 year-old male patient is presented. The confirmatory diagnosis was made by left carotid angiogram, and the aneurysmectomy & reconstruction with woven dacron vascular prosthesis was done, while cerebral circulation was maintained by internal shunt.

  • Although Behcet`s disease, characterized by oro-genital ulceration and ocular abnormalities, is rare and unfamiliar disease to thoracic surgeon, one must remember that it can cause serious complications on the vascular system such as thrombophlebitis,thrombotic obstuction and aneurysm.We report a case of multiple arterial aneurysms with Behcet`s disease. This 31 year-old female had five times surgical interventions during short period[19 months]. 6 aneurysms were developed in this case, 3 were spontaneous aneurysms, 2 were anastomotic aneurysms and 1 was false aneurysm due to arterial puncture.

  • Chronic exposure of arsenic is well known to be the cause of cardiovascular disease such as hypertension. In order to investigate the effect of arsenic on blood vessels. we examined whether arsenic affected agonist-induced contraction of aortic rings in isolated organ bath system. Treatment with arsenite increased vasoconstriction induced by phenylephrine or serotonin in a concentration-dependent manner. (omitted)
