Figure 7. BAL cellularity during allergic airway disease.

Infected neonatal groups with active infections had elevated levels of total WBCs, neutrophils, and eosinophils compared to all other groups (A, C, D). All groups which had allergic airway induced (AAD) with Ova had elevated levels of BAL eosinophils; however group 3 neonates who had active infections but did not have AAD induced had significantly elevated levels of BAL WBCs, neutrophils, and eosinophils when compared to their adult counter parts (P = 0.0001, 0.0003, and 0.0004 respectively); group 1 neonates who had active infections and AAD induced had enhanced levels of BAL WBCs, neutrophils, and eosinophils when compared to all other groups (A, C, D). There was no significant increase in BAL macrophage/monocytes in any group (B).
