SLC12A2 and acute respiratory distress syndrome: The rats that received pretreatment or post-ALI treatment with the NKCC1 inhibitor had higher PaO2/FiO2 ratios than those without NKCC1 inhibitor (p < 0.05, comparing ALI vs. ALI + pre-B, ALI + HG vs. ALI + HG + pre-B, and ALI + HG vs. ALI + HG + post-B groups).
