Fig. 8.
Graphs of PO2 and NADH following repeated episodes of hypoxia (10 min post-hsd) in slices from 1 to 2 months old rats (n = 4). Reoxygenation following the first episode of hypoxia resulted in a PO2 overshoot (increase above baseline) and NADH hyperoxidation (decrease below baseline). During the second episode of hypoxia the NADH fluorescence increase was less than during the first, and the second event was not followed by hyperoxidation. The PO2 overshoot was enhanced after the second episode.
