In order to evaluate the renal excretion quantitatively, the authors analyzed the Tc-99m DTPA renogram using mean transit time (MTT) with deconvolution analysis and compared it to the perfusion index. One hundred thirteen studies consisting of 25 normal, 11 obstruction, 35 transplant-norm, 12 transplant-obstruction, and 30 transplant-rejection were(More)
Renal microcirculation studies utilizing microspheres can provide a highly reliable index of the viability of preserved kidneys. We describe a noninvasive method that permits subsequent transplantation of each tested kidney. Fresh canine kidneys were removed and perfused with either Collins' solution or Collins' solution with 5 mg/l of trifluoperazine(More)
Addition of trifluoperazine (TFP), a powerful calmodulin inhibitor to Collins' flush solution has exerted a significant protective effect on the cold-preserved kidney, with successful autotransplantation of 80% of preserved kidneys (4 of 5) after 72 hr of storage. In contrast, use of Collins' solution alone resulted in successful autotransplantation of only(More)
To test the hypothesis that regional left ventricular filling reflects diastolic changes in contiguous areas of myocardium, we performed radionuclide ventriculograms on normal subjects, patients with left anterior descending coronary artery disease, and patients with anteroseptal myocardial infarctions. We reasoned that because diastolic properties of the(More)
