in eleven chronically catheterized fetal sheep aged 124-142 days , hypotension caused by infusion of sodium nitroprusside ( 1.6-3.3 mg/h ) and competitive antagonism of angiotensin ii by saralasin ( 3.3 mg/h ) both caused a fall in fetal urine flow ( p less than 0.02 and p less than 0.05 , respectively ) , and in sodium excretion ( p less than 0.05 and p less than 0.01 ) because they both caused a fall in glomerular filtration rate ( g.f.r. , p less than 0.02 and p less than 0.01 ) .
