Figure 2. Total leukocyte number and cell type identification in bronchoalveolar lavage (BAL) fluids of OVA-sensitized and airway-challenged BALB/c mice. BAL was performed 24 hours after last allergen aerosol challenge. Stressed mice that were treated with phosphate-buffered saline (PBS) showed significantly higher total cell numbers than nonstressed PBS-injected mice, *p < .017. Application of neurokinin-1 receptor antagonist (NK-1-RA) in stressed mice abrogated the stress-induced increase, #p = .023. Columns represent mean and SEM (Leuko = leukocytes, Lympho = lymphocytes, Eos = eosinophil granulocytes, Gran = neutrophil granulocytes, Macro = Macrophages).
