Immunosuppressed renal transplant recipients are at increased risk for large cell lymphoma of B cell phenotype. This report describes a case of post-transplantation lymphoma presenting with a mediastinal mass causing superior vena cava syndrome, tracheal obstruction, and pleural effusion. Cytospin preparations of pleural fluid documented high-grade lymphoblastic lymphoma morphology and immature T cell (cortical thymocyte) phenotype: Leu 1-6-positive, Leu 9-positive, Tdt-positive, B-negative, Calla-positive. The occurrence of post-transplantation lymphoma of T cell lineage is inconsistent with the postulated Epstein-Barr virus origin and raises important questions regarding the development of lymphoproliferative disorders in immunosuppressed organ transplant recipients. 相似文献

Abstract— In-vitro iontophoresis (0·33 mA cm−2) of calcitonin (50 μg mL−1, pH 4) was performed with the hairless rat skin model. Direct current was as potent as pulse current (2·5 kHz on/off 1/1) iontophoresis in promoting transdermal permeation of calcitonin. Increase in duration of current application from 20 min to 1 h did not increase calcitonin flux. Results suggest that calcitonin can be blocked in the skin pores through which it travels or can accumulate in the skin and be progressively released from the depot. Invivo experiments showed that transdermal iontophoretic administration of calcitonin induced a hypocalcaemic effect in rats. 相似文献

Cognitive changes to preloading in restrained and unrestrained eaters as measured by the Stroop task
Restraint theory has identified overeating in response to a high calorie preload as characteristic of restrained eaters. The present study evaluated cognitive and motivational changes to preloading using both self-report rating scales and Stroop tasks. The results suggest that the restrained eaters responded to a high calorie preload with increased feelings of rebelliousness, defiance, and a desire to challenge the limitations set by the diet, described as an active state of mind, as measured by both the Stroop task and the rating scales. The restrained eaters also showed retardation in the color naming of the body size words and food words after the high calorie preload, suggesting that the consumption of a forbidden food may increase the dieter's concern about food and her shape and weight. The results are discussed in terms of the effects of preloading and possible mediating variables involved in the transition from successful restraint to overeating. © 1993 by John Wiley & Son, Inc. 相似文献

The aim of this study was to investigate the angiogenic response to exogenously administered basic fibroblast growth factor (FGF-2) in normal and ischemic skin, using the hairless mouse ear microcirculatory model. The hairless mouse ear is a well-established model for in vivo studies of skin microcirculation. Using this model, angiogenesis- and angiogenesis-associated changes in the microcirculation can be directly and continuously viewed and quantified in a variety of different experimental settings. To create ischemia in the mouse ear, all but one of the three to four feeding vessels nourishing the ear were ligated 3 days prior to a local subdermal injection of FGF-2 (9.3 + 1–0.5 mm/mm2) or saline into the dorsum of the ears. Angiogenesis was quantified by direct observation, at high magnification, of the injection site where increases in total vessel length (TVL) were measured repeatedly over 18 days following injection. We found a significant (P < 0.01) increase in TVL in normal and ischemic ears injected with FGF-2. Saline injection also induced a significant increase in TVL in ischemic ears. However, the angiogenic response to FGF-2 in ischemic ears was significantly stronger than saline alone in ischemic ears or saline or FGF-2 in normal ears. This response could be used clinically to accelerate angiogenesis and thus increase perfusion in ischemic tissue. © 1997 Wiley-Liss, Inc. MICROSURGERY 17:452–456 1996 相似文献

The efficacy of the non-steroidal anti-inflammatory analgesic, ketorolac (Toradol), was investigated in 52 day case patients undergoing removal of impacted third molar teeth under intravenous sedation and local analgesia. The study was double-blind, randomized and placebo-controlled. A single 30 mg dose of ketorolac was administered intravenously just prior to induction of sedation with midazolam. Ketorolac was well tolerated and provided good postoperative analgesia. It is suggested that ketorolac is a useful addition to the analgesic armamentarium and appropriately prescribed, provides good pain relief following day case oral surgery. 相似文献

Mucocutaneous lymph node syndrome (Kawasaki disease) 总被引:1,自引:0,他引:1
Mucocutaneous lymph node syndrome has rarely been reported in the dental literature despite the orofacial features characteristic of the disease. A case is reported in which the cardinal signs were present: erythema of the oral mucosa, cervical lymphadenopathy, conjunctivitis, pyrexia, and desquamation of the skin of the hands and feet. In addition, hydrops of the gallbladder and cardiac disorder were also found. The patient may first seek treatment by the dental practitioner, by whom the diagnosis may be made. Attention is drawn to the possibility of cardiac abnormalities that may influence dental treatment. 相似文献

A case of dyskeratosis congenita in a 10-year-old white boy is reported. The triad of oral leukoplakia, nail dystrophy, and skin pigmentation was present. Other associated anomalies included dysphagia and varied immunoglobulin levels, although there was no evidence of anemia, pancytopenia, and ocular involvement. Since it may be associated with future malignant change, dyskeratosis congenita should be considered in all cases in which an obscure white lesion exists in the mouth. 相似文献
