BAL cells and proteins in normoxia, hypoxia/reoxygenation and effects of inhaled NO. (A) the BAL total leukocyte (white bars) and neutrophil (gray bars) counts in wild-type and transgenic sickle SAD mice under normoxia conditions (n = 12 in each group) are reported. (B-D) BAL total leukocyte count, neutrophil count, and total protein content in wild-type mice (closed triangles), in SAD mice exposed to hypoxia/reoxygenation alone (open boxes), and in SAD mice breathing inhaled NO (open circles) (n = 6 in each group). Values are expressed as means + SEMs. ^*P < .05 compared with baseline, °P < .05 hypoxia/reoxygenation versus hypoxia/reoxygenation plus NO, as determined by ANOVA with post hoc Bonferroni corrected t test.
