Transient and sustained increases in glomerular permeability following ANP infusion in rats.
The present study was performed to investigate the effects of systemic atrial natriuretic peptide (ANP) infusion on the glomerular permeability to macromolecules in rats. In anaesthetized Wistar rats (250-280g) the left urether was cannulated for urine collection while simultaneously blood access was achieved. Rats were continuously infused i.v. with ANP, 30 ng/min/kg (Lo-ANP; n=8) or 800 ng/min/k
