Eighteen opossums received 2250 rad60Co to the entire esophagus and lower esophageal sphincter. Animals received treatment with 600 mg aspirin, 25 mg/kg hydrocortisone, or saline before irradiation and twice daily for 1 week after irradiation. At 10 days postirradiation, animals were evaluated for signs of acute esophagitis by esophagoscopy and barium esophagram. Each animal was then killed and the esophagus removed and evaluated histologically. Animals treated with either aspirin or hydrocortisone had significantly milder esophagitis than control irradiated animals.Supported by IN-121 from the American Cancer Society. 相似文献

BACKGROUND: Survival 10 years after orthotopic liver transplantation now approaches 65%. Consequently, community doctors must manage the metabolic and neoplastic complications of orthotopic liver transplantation in an ageing population. AIMS: To review common sources of morbidity and mortality in long-term orthotopic liver transplantation recipients, and to make evidence-based recommendations regarding their management. METHODS: Pertinent studies and reviews were identified by literature search through PubMed. Where evidence-based recommendations could not be gleaned from the literature, expert opinion was obtained from syllabi of national meetings. RESULTS: The two most common causes of morbidity and mortality in orthotopic liver transplantation recipients are atherosclerotic vascular disease and de novo malignancy. The pathogenesis of many complications begins before orthotopic liver transplantation, and many are potentially modifiable. Most complications, however, can be directly ascribed to immunosuppressive agents. Despite improvements in our understanding of the pathogenesis and epidemiology of the metabolic and neoplastic complications of orthotopic liver transplantation, remarkably few randomized-controlled studies exist to define their optimal management. CONCLUSIONS: Orthotopic liver transplantation recipients experience and succumb to the same afflictions of old age as non-transplant patients, but with greater frequency and at an earlier age. Most recommendations regarding surveillance for, and treatment of, medical complications of orthotopic liver transplantation remain based upon expert opinion rather than evidence-based medicine. 相似文献

The authors assessed the association between an elevated total cholesterol to high-density lipoprotein cholesterol (TC/HDL-C) ratio (≥4) and proximal coronary artery disease (CAD), as observed on multislice computed tomography. Coronary multislice computed tomographic angiography (96% on 40- or 64-slice) was performed in 295 individuals (39% women; mean age, 54±13 years) without documented CAD who were referred for coronary evaluation. Significant CAD was defined as ≥50% stenosis in the left main, proximal left anterior descending, or ≥2 epicardial vessels. Proximal plaque was defined as presence of any plaque in left main or proximal left anterior descending vessels. Individuals with an elevated TC/HDL-C ratio vs those without had a higher prevalence of proximal plaque (62% vs 48%, P =.04) and significant CAD (19% vs 9%, P =.009). On multivariate logistic regression analysis, only age, sex, and TC/HDL-C ratio ≥4 were associated with significant CAD and proximal plaque. 相似文献
