Early endothelial injury may play a role in the development of transplant arteriosclerosis. The present study documents early endothelial changes using a rat aortic graft model. Abdominal aortic allografts from PVG rats were orthotopically transplanted to DA rats. Controls were DA to DA transplants. Endothelial cell (EC) injury, regeneration, and leukocyte(More)
The influence of cytokines on the inflammatory response in surgery has recently been the subject of investigations. We measured tumor necrotic factor-alpha (TNF-alpha), interleukin 1 beta (IL-1 beta), interleukin 6 (IL-6), interleukin 8 (IL-8), and granulocyte elastase (GEL) in 26 patients undergoing elective cardiac operations using cardiopulmonary bypass(More)
The aim of this study was to determine whether the preoperative administration of lentinan, which is used clinically to activate T cell function in cancer patients, prevents the impairment of lymphocyte function after cardiopulmonary bypass (CPB). A total of 25 adults undergoing coronary artery bypass grafting were enrolled in this study. Lentinan (2 mg)(More)
We report a case of nonocclusive mesenteric ischemia (NOMI), which developed after Y-grafting for a ruptured abdominal aortic aneurysm (AAA). A 71-year-old man was referred to our hospital with severe abdominal pain and signs of shock. Computed tomography revealed a ruptured AAA, and emergency aneurysmectomy and aortic grafting were performed. However, on(More)
The present study evaluated the risk in cardiac patients of rupture of a plaque by a jet stream from the arch cannula. The entire thoracic aorta and cardiac function were routinely monitored by transesophageal echocardiography (TEE) in 88 adult patients who underwent coronary artery bypass surgery. The changes in the atheromatous plaque in the distal aortic(More)
Perfusion from the femoral artery is commonly used in the open proximal method of performing distal aortic arch aneurysm repair or Stanford type B aortic dissection repair under circulatory arrest through left thoracotomy. However, it is associated with a significant risk of retrograde emboli or malperfusion, and with other problems including a restricted(More)
BACKGROUND The effects of cardioplegic arrest and reperfusion on the coronary vasculature remain to be characterized. This study was designed to investigate changes in coronary reserve and autoregulation after hypothermic cardioplegic arrest and reperfusion. METHODS Isolated rabbit hearts were perfused in a retrograde manner with Krebs-Henseleit(More)
This study was conducted to examine whether mixed lymphocyte culture (MLC) could be used as a predictor of the efficacy of anti-CD4 monoclonal antibody (MAb) immunosuppression in vivo in a mouse model. C57BL/10 or BALB/c hearts were transplanted into C3H.He recipients. Anti-CD4 MAb administration prolonged graft survival, but there was a clear difference(More)
Depression in electroencephalogram (EEG) has been documented clinically and is reproducible in swine at the initiation of cardiopulmonary bypass (CPB) utilizing a crystalloid prime. The physiological cause of this transient alteration in electrical brain activity appears to be associated with the transient drop in arterial pressure. The etiology is unknown(More)
Histopathological examination of a repair of left ventricular free wall rupture associated with acute myocardial infarction using GRF glue was reported. A 63-year-old male with cardiac rupture due to LMT total occlusion was referred to our ward after unsuccessful PTCA with institution of IABP and PCPS. Left ventricular rupture repair by GRF glue and(More)
