The nephrectomized patient maintained on intermittent hemodialysis while awaiting renal transplantation provides an excellent model for studying the influence of factors other than the renal renin-angiotensin system that play a role in the regulation of plasma aldosterone concentration. Peripheral plasma aldosterone concentrations were determined using a(More)
Monocytes were isolated from fresh whole human blood and resuspended in Hanks balanced salt solution; a portion of the cells was mixed with an equal volume of 2M dimethyl sulfoxide (DMSO) to form a 1 M solution. Microliter volumes of cell suspension were placed directly onto a computer-controlled cryostage and cooled to a predetermined subzero temperature.(More)
The response of plasma aldosterone concentration to postural variation, adrenocorticotropic hormone (ACTH), and angiotensin II was studied in five kidney allograft recipients and compared with the response observed in the same five subjects during the anephric period. Normal subjects acted as intact controls. After 2 hours of normal ambulation, plasma(More)
The renal artery to a sole remaining kidney was constricted in unanesthetized dogs while renal arterial pressure was recorded distal to the occluder. Following the constriction, mean arterial blood pressure, which was continuously monitored 24 hours a day for 1 week, exhibited a biphasic increase. The first peak in pressure correlated with a large increase(More)
The aldosterone response to long-term infusion of angiotensin II and potassium was studied in intact conscious dogs. Plasma aldosterone concentration (PAC), plasma renin activity (PRA), and plasma cortisol concentration (PCC) were determined by radioimmunoassay. In ten dogs maintained on angiotension II infusion (5 ng/kg min-1) for 14 days, PAC increased(More)
Twenty patients with keratoconjunctivitis sicca used three different viscoelastic tear formulations and a polyvinyl alcohol artificial tear for two weeks each. Each formulation was used once every two waking hours in a controlled double-masked study. Eighteen patients reported marked improvement over the course of the study, in terms of the severity of(More)
