Synthesis of total phospholipids (TPL) in the mature rat lungs. The amounts of radiolabeled TPL (cpm/g body weight) recovered from bronchoalveolar lavage fluid (BALF), and in the total lungs [i.e. in both lung tissue after lavage and BALF], were determined in lipopolysaccharides (LPS)-treated (black diagrams) and non-treated control (C, white) rats. Definition of subgroups (n = 8 each): Air, room air; ONO, 95% oxygen and nitric oxide in 20 parts per million; O, 95% oxygen; and NO, nitric oxide 20 parts per million. Definition of each subset figures: A-B, 4 h; C-D, 24 h; A and C, [³H] TPL in BALF; B and D, [³H] TPL in the total lungs. Values are means ± SD. §§ p < 0.01 versus all other subgroups; # p < 0.05, ## p < 0.01 versus the corresponding C subgroup.
