...David G. SHIRLEY; Mary F. WALTER; Stephen J. WALTER; Andrew THEWLES; Christopher J. LOTE Uncertainties exist over the glomerular filtration of aluminium and virtually nothing is known about its segmental handling along the nephron. The present study has used micropuncture, combined...

...D. G. Shirley; S. J. Walter; R. J. Unwin 1. The nephron sites involved in the blunted natriuretic response to frusemide during sodium depletion were investigated using micropuncture techniques in anaesthetized rats. 2. Glomerular filtration rate was lower, and fractional sodium reabsorption...

... (Na + ) and lithium (Li + ) in rats by means of free-flow micropuncture at the late proximal tubule and the early distal tubule. 2. Endogenous angiotensin II was suppressed by pretreament with enalapril. Compared with a control group, angiotensin II increased mean arterial pressure by 15 mmHg...

...S. J. Walter; A. C. Shore; D. G. Shirley 1. In order to investigate the effects of K + depletion on renal function, micropuncture studies were performed on anaesthetized rats which had been kept on a K + -deficient diet for 2 weeks; results were compared with those from control animals. 2. In the K...

Because the kidney has an important role in both magnesium and potassium homeostasis, clearance and micropuncture...

...S.-F. Wen; R. W. Stoll 1. Clearance and micropuncture studies were performed in 27 dogs made uraemic by segmental infarction to examine the factors responsible for phosphate adaptation in chronic renal failure. 2. The animals were studied before and after extracellular volume expansion to 10...

In the present work the tubular response to EHDP (0.16 mmol/kg body wt.) injected subcutaneously for 9 days has been localized by free-flow micropuncture in thyroparathyroidectomized rats. 3. The results show that the net tubular reabsorption...

Clearance and micropuncture studies were performed in 19 thyroparathyroidectomized dogs to examine the inter-relationship between the renal transport of sodium, glucose and phosphate. 2.
