Effect of hypercapnic acidosis on major markers in BALF in rats’ lungs induced by high-pressure ventilation (HPV) for 4 h. (A) Bronchoalveolar lavage fluid (BALF) total protein levels (microgram/ml) were augmented by high-pressure ventilation but diminished by both hypercapnic groups. (B, C) The total and neutrophil cell count in the lavage group increased following HPV but were attenuated in the hypercapnic groups. (D) Pulmonary edema formation was quantified by measuring the wet and desiccated dry weights of the lung tissue. n = 8 for each group.^ap < 0.05 versus the NV group;^bp < 0.05 versus the NC group;^cp < 0.05 in the SHA group versus the MHA group.
