The expression of heat shock proteins (HSP) of the 65 kD family (groEL) has been observed by flow cytometry using murine monoclonal antibody (MoAb) anti-HSP 65 kD (ML30) on the surface of B (Daudi) or T (H9) lymphoma cells, on a monocyte cell line (U937) and also on a primary culture of a human pancreatic carcinoma (HPC). Moreover, the MoAb ML30 was coupled to Saporin 6, a ribosome-inactivating protein recovered from the seeds of Saponaria officinalis, to kill HSP-expressing cells with a specific immunotoxin. An indirect method using first MoAb ML30 and then anti-mouse IgG1 immunotoxin was also performed. With this method a human serum positive for HSP65-antibodies was tested using anti-human IgG1 or IgM immunotoxins. All cell lines were inhibited when preincubated with the specific immunotoxin directed to HSP65 (ML30 SO6), although H9 cells were susceptible to immunotoxin only after thermal stress. Daudi and HPC cells were inhibited both after long-term culture and when freshly explanted from SCID mice. Proliferation of the U937 monocytic cell line, that constitutively expresses high levels of HSP65 on the surface (as determined by flow cytometry), was completely inhibited (100% inhibition) by the ML30 SO6. However, not all tumour cells constitutively express high levels of surface HSP65, as determined by cytometric analysis. For this reason it was not always possible to obtain complete inhibition of cellular proliferation. 相似文献

Off-pump coronary artery grafting in patients with left main coronary artery disease 总被引:1,自引:0,他引:1

BACKGROUND: Left main coronary artery disease (LMCD) is considered a relative contraindication to off-pump coronary artery bypass (OPCAB) grafting. This study evaluates the safety and feasibility of OPCAB in these patients compared to an on-pump group (cardiopulmonary bypass, CPB) with LMCD. METHODS: Between January 2000 and July 2002, 95 patients with left main coronary artery stenosis >50% underwent coronary revascularization. Seventy-three unselected patients underwent OPCAB and 22 underwent revascularization using CPB. The techniques used for OPCAB included the use of deep traction sutures in the posterior pericardium and stabilizers to expose the distal coronary targets. Intraluminal coronary shunts were routinely used during construction of the anastomoses. Variables were analyzed using a Student's paired t-test with statistical significance defined as p < 0.05. RESULTS: The mean age in the OPCAB group was 59.9 years and the CPB group 61.8 years (p = 0.54). There were 56 males (77%) in the OPCAB and 18 (82%) in the CPB groups. Mean preoperative left ventricular ejection fraction (LVEF) was 40.3% in OPCAB and 47.3% in CPB (p = 0.015). Average number of grafts was 3.1 in OPCAB and 4.1 in CPB (p = 0.0038). There were no conversions to CPB in those patients initially chosen to undergo OPCAB. There were no early deaths in OPCAB. There was one death in CPB. Mean hospital length of stay was 6.9 days for OPCAB and 9.1 for CPB (p = 0.0159). CONCLUSIONS: Patients with LMCD can undergo OPCAB grafting safely and effectively despite reduced LVEF. LMCD should no longer be seen as a contraindication to perform OPCAB grafting. 相似文献

Background
Pectus excavatum is the most frequent malformation of the rib cage. Functional aspects associated with this malformation often are absent even in adults not involved in competitive sports activities. Overall, these patients often live with extreme psychological discomfort when the malformations are minor. Traditionally, the correction of these malformations has been geared toward interventions that modify the architecture of the rib cage. However, all these interventions, even the most recent, involve considerably invasive major surgery. In fact, optimal results are not always achieved with corrective surgery using the insertion of silicone prosthesis, and patients often experience complications.Methods
To correct intermediate and modest pectus excavatum in a stable manner and with the least amount of invasiveness, the authors developed a camouflage technique that uses porous prostheses made from high-density linear polyethylene. This material is generally used for reconstruction of the brain case. Between February 2001 and March 2006, in the I Unit of Plastic Surgery of the authors’ Institute, 11 adult pectus excavatum patients with no previous cardiorespiratory symptoms underwent the authors’ surgical technique. The average patient age was 29 years.Results
Surgical repair was successful in all cases, and the average hospital stay was short. There were no complications during the follow-up period. The described approach repairs nonfunctional pectus excavatum in the adult with satisfying aesthetic and stable results, short hospital stay, and high patient popularity ratings.Conclusions
The best therapeutic option for pectus excavatum, especially with intermediate or moderate severity, is still controversial: thoracic surgery or camouflage surgery with implant? Trying to address those issues we propose a new technique by a multidisciplinary, not aggressive approach using a high density linear polyethylene implant and Omentus flap and the early analysis of our data.7.

Introduction
Metabolic syndrome (MS) is an important cardiovascular risk factor. The aim of this study was to evaluate the incidence of MS in an Italian kidney transplant recipient population and its relationship to the incidence of major adverse cardiovascular events (MACE) after renal transplantation.Methods
The prevalence of MS was evaluated according to the National Cholesterol Education Program Adult Treatment Panel III criteria among adult recipients who underwent a renal transplant between January 1997 and December 2007. In this period, we prospectively recorded the incidence of MACE to be related to the presence of MS.Results
We included 425 kidney transplant recipients in the study including 62% males and an overall median age 46 years (interquartile range = 36-54). The prevalence of MS was 41.2% at 6 months after transplantation and 46.6% at 5 years. During the follow-up (median = 5.1 years), 32 patients (7.5%) experienced at least one MACE. The detection of MS at 6 months after transplantation was significantly associated with an increased risk of MACE occurrence (MS IRR = 2.2 P = .05).Conclusions
Our findings indicated that MS was largely present in the transplant population confirming that as in the general population, it was a significant risk factor for the occurrence of severe cardiovascular disease. Early identification and treatment of patients with MS may improve long-term patient survival. 相似文献9.

Polyorchidism is a rare congenital anomaly. A review of literature has yielded about 100 cases. We describe a rarer case of polyorchidism consisting of 3 testes on left hemiscrotum and one normal testis in right hemiscrotum. Diagnosis and management are discussed. 相似文献
