By continuous monitoring of a solid meal labelled with a radiopharmaceutical it has been possible to determine the effects of drugs on gastric emptying and motility during a single study. Predictably hyoscine delayed, and bethanechol increased, the rate of gastric emptying. Pentagastrin initially produced marked antral activity resulting in a physiological(More)
The effects of proximal gastric vagotomy (PGV) and vagotomy with pyloroplasty (V and P) on gastric motility were studied using a solid meal labelled with a radiopharmaceutical agent. In having on-line computer facilities it was possible not only to record the rate of emptying but also to analyse the relative roles of the fundus and the antrum within the(More)
Fifty new cases of carcinoma of the prostate were assessed prior to treatment to determine the incidence of bony metastases. The radioisotope bone scan was the most sensitive method of detecting metastases and of localising them. It was twice as accurate as the serum acid phosphatase estimation. Skeletal X-rays were the least accurate method. Forty-six per(More)
The present study was designed to investigate the role of 5-lipoxygenase (5LO) metabolites in an endotoxin (LPS)-induced model of the adult respiratory distress syndrome (ARDS) in the rat. The therapeutic value of two 5LO inhibitors and a specific LTB4 and a LTD4 receptor antagonist were examined. Rats were treated 1 hr prior to administration of(More)
The protective effects of altered arachidonic acid metabolism, using either methylprednisolone or a dual cyclooxygenase and 5-lipoxygenase inhibitor (SK&F 86002), were compared in a rat model of adult respiratory distress syndrome (ARDS). Rats were either unexposed (n = 9) or pretreated with vehicle (n = 25), 100 mg/kg SK&F 86002 (n = 8) or 30 mg/kg(More)
Current strategies for the treatment of ARDS have been unsuccessful in reducing mortality. In the present study, we have evaluated the role of cyclooxygenase (CO) products in a rat model of ARDS by testing naproxen, indomethacin, ibuprofen, and a thromboxane A2 (TXA2) receptor antagonist (SK&F 96148). Rats were treated 1 hr prior to endotoxin (LPS) exposure(More)
The prognostic significance of left ventricular ejection fraction measurements obtained at the bedside was assessed in 171 patients as soon as possible after acute myocardial infarction. Ejection fraction was measured with a radionuclide first pass portable probe method within a mean of 24 hours of the onset of major symptoms. The results were related(More)
To ascertain the ophthalmic complications after heart transplantation, the authors reviewed 59 patients who had been referred to the ophthalmology department during a 4-year period and were subsequently followed for at least 1 year. Twenty-five patients (43%) were found to have lens changes in one or both eyes, which is typical of prolonged oral(More)
