Effects of hyperoxia and incremental IH episodes on kidney weights (panels A and B) and kidney/body weight ratios (panels C and D) in neonatal rats at P7 or P14 (open bar) and P21 (solid bar). P7 animals were exposed to brief clustered IH episodes during hyperoxia (50% O2) or constant 50% O2 from P0 to P7. P14 animals were exposed to brief clustered IH episodes during 50% O2 or constant 50% O2 from P0 to P14. P21 animals were exposed to constant 50% O2 or brief clustered IH episodes during 50% O2 from P0 to P7 or P0 to P14 then placed in RA from P7 to P21 or P14 to P21 for re-oxygenation. Control animals were raised in room air (RA) from P0-P7, P0-P14 or P0-P21. Data are presented as mean ± SEM (n = 18 samples/group)
