From: Aerosolised surfactant generated by a novel noninvasive apparatus reduced acute lung injury in rats
Exogenous surfactant reduced pulmonary oedema and inflammatory response. (a) Lung index (lung/body weight ratio), (b) total protein contents and (c) TNF-α concentration in bronchoalveolar lavage fluid (BALF). Mean ± standard deviation in animals in the model and saline groups (n = 7) and in the porcine pulmonary surfactant (PPS) groups (n = 10). * P < 0.01 compared with the model group. $ P < 0.01 compared with the saline-inst group.# P < 0.01 compared with the saline-aer group. Aer = aerosolisation; Inst = intra-tracheal instillation.
