Angiotensin-converting enzyme (ACE) activity in bronchoalveolar lavage fluid (BALF). Results are presented as medians (range); n = 4 animals per group. *P < 0.05 for HiP-C group vs. HiP-Met and LoP-C groups. LoP-C: low pressure-no metformin; LoP-Met: low pressure-metformin; HiP-C: high pressure-no metformin; HiP-Met: high pressure-metformin; FU: fluorescence units.
