Concentration of parameter in BALF with two delivery devices. (A) Concentration of albumin in BALF using gavage needle, (B) Concentration of albumin in BALF using microspray aerosolizer, (C) Concentration of protein in BALF using gavage needle, (D) Concentration of protein in BALF using microspray aerosolizer, (E) Concentration of CINC-1 in BALF using gavage needle, (F) Concentration of CINC-1 in BALF using microspray aerosolizer. No difference was observed between delivery devices for these factors. (N.C.; Negative control, *p<0.05, **p<0.01)
