Protein C has been purified from the plasma of a patient with thrombotic diathesis. Both before and after isolation, the protein showed reduced capacity to hydrolyze synthetic substrates and to anticoagulate plasma. Proteolysis with the soluble thrombin- thrombomodulin complex proceeded normally and to completion as judged by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and Western blotting. Approximately one-third of the protein is functional, indicating a heterozygous defect. Indirect studies suggest that the abnormal component can bind to protein S and phospholipids. Both forms of activated protein C can also incorporate radiolabeled diisopropylfluorophosphate. 相似文献

Localization of pancreatic insulinoma: comparison of pre- and intraoperative US with CT and angiography 总被引:2,自引:0,他引:2

Methods of preoperative radiologic localization of insulinoma were compared in 52 patients, 44 of whom had solitary tumors. Examinations performed in these 44 patients were preoperative ultrasonography (US) in 28, angiography in 26, and computed tomography in 23. Prospective sensitivities were 61%, 54%, and 30%, respectively. Imaging sensitivities were lower for the eight patients with multiple insulinomas. In 28 of the 44 patients, intraoperative US was performed without the examiner being aware of the surgical findings. The sensitivity was 84%. Four insulinomas were not palpable but were visualized sonographically. The combined sensitivity of intraoperative US and surgical palpation for detecting solitary insulinomas was 100%. High-frequency intraoperative US is valuable for detecting occult solitary insulinomas and considerably useful for determining the proximity of insulinomas to the pancreatic and bile ducts. 相似文献

Radiological assessment of dysphagia with endoscopic correlation 总被引:1,自引:0,他引:1
Four hundred fifty consecutive patients with dysphagia were evaluated radiologically over a 14-month period; 127 of these (28.2%) were also examined endoscopically. The most common abnormality seen was dysmotility (34%), followed by hiatal hernia, benign stricture, and esophagitis. Correlation with endoscopy was generally good. Radiologic study demonstrated all cases of esophageal malignancy; radiologic/endoscopic correlation was also strong in patients with moderate or severe esophagitis, though the radiologist had some difficulty detecting mild inflammation. Endoscopy failed to demonstrate some benign strictures. Radiologic study was relatively accurate in detecting significant organic disease; most motility disorders were not detected by endoscopy. For these reasons, as well as lower cost, increased convenience, and patient comfort, radiologic assessment is recommended as the primary method of evaluating patients with dysphagia. 相似文献

We describe five children who died of clinical rabies in a three month period (September to November 2011) in the Queen Elizabeth Central Hospital. From previous experience and hospital records, this number of cases is higher than expected. We are concerned that difficulty in accessing post-exposure prophylaxis (PEP) rabies vaccine may be partly responsible for this rise. We advocate:(a) prompt course of active immunisation for all patients with significant exposure to proven or suspected rabid animals. (b) the use of an intradermal immunisation regime that requires a smaller quantity of the vaccine than the intramuscular regime and gives a better antibody response. (c) improved dog rabies control measures 相似文献
