net 3-h-pge2 recoveries from the microinjected kidney were similar following injections into early ( 61.2 plus or minus 6.8 % ) and late ( 62.9 plus or minus 7.9 % ) proximal tubules , but significantly higher after injection into distal tubules ( 91.3 plus or minus 7.0 % ) indicating absorption of 3-h-pge2 in the loop of henle but not in the proximal and distal nephron .
