Seizures and lung injury in awake animals in HBO₂ at 5 ATA; 79% of freely moving control animals pretreated with aCSF alone exhibited tonic-clonic convulsions with a mean latency of 37 ± 8.2 min. By contrast, 28% of animals pretreated with l-NAME exhibited convulsions, with a mean latency of 56 ± 3.1 min (A). Postmortem assay of bronchoalveolar lavage fluid (BALF) in the aCSF control animals revealed pronounced pulmonary protein leakage, whereas the l-NAME group showed much less injury (B). *P < 0.05 vs. air; #P < 0.05 vs. aCSF controls.
