The influence of circulating catecholamines and prostaglandins on canine renal hemodynamics during hemorrhage.
The relationship between circulating catecholamines and prostaglandins and the independent contribution of circulating catecholamines to renal vasoconstriction during hemorrhage is unknown. The renal hemodynamic effects of a 30% decrease in blood pressure by hemorrhage were therefore studied in three groups of anesthetized dogs which had undergone prior bilateral renal denervation. A constant u...
متن کاملRenal Function and Systemic Hemodynamics
This study examined the control of renal hemodynamics and tubular function, as well as systemic hemodynamics, during obesity-induced hypertension in chronically instrumented conscious dogs. Mean arterial pressure, cardiac output, and heart rate were monitored 24 hours a day using computerized methods, water and electrolyte balances were measured daily, and renal hemodynamics were measured each ...
متن کاملControl of renal hemodynamics and glomerular filtration rate in chronic hypercalcemia. Role of prostaglandins, renin-angiotensin system, and calcium.
The role of prostaglandins (PG), renin-angiotensin system (RAS) and calcium (Ca) in the control of renal hemodynamics and glomerular filtration rate (GFR) in chronic hypercalcemia (serum Ca 12.8 mg%) was studied. Renal blood flow (RBF, 6.39 ml/min per gram kidney weight [gkw]) and GFR (0.52 ml/min per gkw) were significantly decreased in hypercalcemic rats when compared with normocalcemic rats ...
متن کاملRegulation of Renal Hemodynamics
B eginning the renal physiology section with a detailed consideration of renal microvascular dynamics allows a smooth transition from cardiovascular-related topics to kidney-related topics. In addition, reductions in renal blood flow (RBF) and glomerular filtration rate (GFR) are often associated with many pathophysiological conditions including hypertension, renal failure, heart failure, and d...
متن کاملRenal function in fulminant hepatic failure: haemodynamics and renal prostaglandins.
Eighteen patients with fulminant liver failure were studied, 10 with normal renal function (group A) and eight with renal failure (group B, plasma creatinine greater than 200 mumol/l). Renal function was assessed by standard clearance techniques and patients in group B had a marked reduction compared with group A in both renal plasma flow and glomerular filtration rate. Raised plasma renin acti...
