Association of GSTP1 polymorphism and survival for esophageal cancer.

Purpose: Activity of glutathione S-transferase (GST) is associated with detoxification of xenobiotics and the maintenance of cell viability. Genetically variant GSTs produce different enzymatic activities. The clinical significance of this variation is still puzzling.

Prognostic significance of six-month estimated glomerular filtration rate in cadaveric renal transplantation.

Background And Purpose: We hypothesized a linear relative-risk model for graft survival of cadaveric renal transplantation, with a 6-month estimated glomerular filtration rate (GFR) employed as the linear parameter quantifying functioning renal mass and the detrimental effects of early chronic allograft nephropathy.

Methods: A retrospective study was conducted in a 15-year series of cadaveric renal transplantations (n = 227) with cyclosporin-based immunosuppression in a single transplant center. The Cockcroft-Gault formula was used for estimation of GFR, with a correction factor of 0.

Effect of Surgecel coverage with topical electrocauterization for preventing and sealing pulmonary air leakage.

Pleural tears usually occur after pneumolysis for dense adhesion or after cone biopsy of lung parenchyma. Repair of the tears is sometimes very difficult. Herein we compared different methods on a pig lung air leak model.

Video-assisted thoracic surgery for spontaneous pneumothorax: outcome of 189 cases.

The crucial role of video-assisted thoracic surgery (VATS) in the treatment of spontaneous pneumothorax is well acknowledged today. Experiences of such patients undergoing VATS were reported to evaluate the feasibility of such surgical approach. From January 1, 1996 to January 1, 2002, 189 patients (18.

Safrole-DNA adducts in tissues from esophageal cancer patients: clues to areca-related esophageal carcinogenesis.

Epidemiological studies have demonstrated that areca quid chewing can be an independent risk factor for developing esophageal cancer. However, no studies are available to elucidate the mechanisms of how areca induces carcinogenesis in the esophagus. Since the areca nut in Taiwan contains a high concentration of safrole, a well-known carcinogenic agent, we analyzed safrole-DNA adducts by the 32P-postlabelling method in tissue specimens from esophageal cancer patients.

Acute hemodynamic study of Tai-Ta left ventricular assist device in a canine model.

A revised Tai-Ta centrifugal impeller pump was designed to study the interaction of the left ventricular assist device (LVAD) with the cardiovascular system in a canine model. Six healthy dogs weighing 12-16 kg were used. Blood flows in the aortic arch, the pulmonary artery (PA), and the LVAD outlet were measured simultaneously with the arterial blood pressure (ABP), the pump outflow pressure (POP), and the electrocardiograph (ECG).

Rapid detection of human HLA transgenes in pigs by fluorescence in situ hybridization (FISH) for adjuvant study of human xenotransplantation.

Objectives: We have recently generated several lines of transgenic pigs for HLA-DP and -DQ to elucidate the role of HLA-II antigens in the modulation of cell-mediated rejection of xenotransplantation. Using fluorescence in situ hybridization (FISH) analysis, the aim of this study was to determine integration sites and to test zygosity of these transgenes in the piglets after cross mating.

Methods: Blood lymphocytes of transgenic pigs for HLA-DP and -DQ were collected and cultured.

Comparison of histidine-tryptophan-ketoglutarate and Euro-Collins solutions for lung preservation using the minipig in situ warm ischemia model.

Background And Purpose: Reperfusion injury remains a common problem in lung transplantation. This study compared the effect of lung preservation with histidine-tryptophan-ketoglutarate (HTK), a relatively low potassium solution, and Euro-Collins (EC) solution by using a minipig in situ model of warm ischemia.

Methods: The left lungs of 5 minipigs were selectively flushed with EC solution.

The role of B7 ligands (CD80 and CD86) in CD152-mediated allograft tolerance: a crosscheck hypothesis.

Background: The regulatory mechanism by which the B7 ligands (CD80 and CD86) direct the CD28/CD152 costimulatory pathways is unclear. This study investigated the role of CD80 and CD86 in a CD152-mediated allograft tolerance model.

Methods: A low-responding cardiac transplant model (BALB/c-->B10.

Enduring effects of thoracoscopic Heller myotomy for treating achalasia.

Minimal invasive surgery using a laparoscopic or thoracoscopic approach for cardiomyotomy (Heller myotomy) has become a widely accepted procedure to treat achalasia of the esophagus. In this study, we evaluated the long-term results of Heller myotomy achieved by performing video-assisted thoracic surgery (VATS). We recruited patients with achalasia who had undergone VATS for Heller myotomy from 1991 to 2000 at the National Taiwan University Hospital.

Efficacy of low-dose mycophenolate mofetil therapy for Taiwanese renal transplantation patients receiving primary cyclosporine immunosuppression.

Background And Purpose: Mycophenolate mofetil (MMF) in combination with cyclosporine or tacrolimus prevents acute rejection and chronic allograft failure in renal transplantation in Western countries. We began to add low-dose MMF to primary cyclosporine immunosuppressive therapy in renal transplantation at the Department of Surgery of National Taiwan University Hospital in 1998. This study compared low-dose MMF to conventional therapy in Taiwanese renal transplant recipients.

Handport-assisted laparoscopic living-donor nephrectomy; initial experience in Taiwan.

The feasibility of handport-assisted laparoscopic living-donor nephrectomy in Taiwan was assessed by comparison with conventional open nephrectomy. Six serial patients undergoing laparoscopic living-donor nephrectomy (LLDN) were compared with six patients undergoing open donor nephrectomy. Body-mass index (BMI), operating time, hospital stay, and short-term graft function were assessed in both groups of patients.

Poland's syndrome with spontaneous pneumothorax: report of two cases.

Poland's syndrome is an uncommon congenital anomaly of the chest wall characterized by the absence of the pectoralis major muscle and other nearby musculoskeletal components. Many associated aberrations over the thoracic cage, intrathoracic organs, and upper limbs have been reported. However, spontaneous pneumothorax in these patients has not been reported.

Reduction of human-to-pig cellular response by alteration of porcine MHC with human HLA DPW0401 exogenes.

Background: In pig-to-human discordant xenotransplantation, the xenograft can be rejected by a formidable human xenogenic T-cell response, even if the graft has gone through hyperacute rejection or delayed xenograft rejection (acute vascular rejection). We therefore examined, in this study, whether the human-to-pig cellular response could be attenuated through the generation of a transgenic pig for human HLA II.

Methods: With the technique of microinjection, we produced the HLA DPw0401 transgenic pig.
