BALF antiprotease enrichment after the first 4 h, due to increased capillary-alveolar concentration gradient without further increase in permeability. a Changes in BALF α1-AT bioactivity and BALF total protein content between 4 h and 24 h after instillation. At 24 h, while total protein content falls 40 %, BALF α1-AT bioactivity increases 18 % above values observed at 4 h. b Changes in BALF α2-MG concentration and BALF total protein content between 4 h and 24 h after instillation. At 24 h, while total protein content falls 40 %, BALF α2-MG concentration increases 281 % above values observed at 4 h. h: hours
