Basal cell carcinoma represents the most common skin cancer and involves the head and neck area in 80% to 85% of all patients treated. Despite their frequent occurrence, metastatic spread from these tumors is rare. This paper presents a case of a patient who had a metastasizing basal cell carcinoma. Despite control of primary disease by radical surgery and adjunctive irradiation, bony metastasis was found within nine months of therapy. Palliative therapy was given, but the patient died five months later. The pathophysiology of the metastasizing basal cell carcinomas is described, and a rationale for therapy presented. 相似文献

The presentation and clinical course of pure red cell aplasia in 5 patients are described. In 3 of them no concomitant diseases were present, in 1 the condition was associated with the presence of a thymoma, and the remaining patient was suffering from a lymphocytic lymphoma. Pregnancy led to a recurrence of the disorder in 2 patients. The fact that 4 of the patients exhibited unequivocal evidence of other auto-immune disturbances adds further support to the concept that pure red cell aplasia itself has an auto-immune basis. 相似文献

A dextran density gradient centrifugation method has been used to separate PHA transformed lymphocytes from nontransformed lymphocytes obtained from rat blood. Fifty-four percent of the transformed lymphocytes were recovered in the fraction at a density of 1.0620 g/ml. Eighty-five percent of the cells in this fraction were transformed cells while the remainder were non-transformed lymphocytes. 相似文献

An event sequence recorder is a specialized piece of equipment that accepts inputs from switches and contactors, and prints the sequence in which they operate. This paper describes an event sequence recorder based on an Intel 8085 microprocessor. It scans the inputs every millisecond and prints in a compact form the channel number, type of event (normal or abnormal) and time of occurrence. It also communicates these events over an RS232C link to a remote computer. A realtime calendar/clock is included. The system described has been designed for continuous operation in process plants, power stations etc. The system has been tested and found to be working satisfactorily. 相似文献
