Delayed Asthmatic Response to Allergen Challenge and Cytokines Released by Nonspecifically Stimulated Blood Cells

Figure 1

Delayed asthmatic response to allergen challenge (DYAR) and phosphate buffered saline (PBS) control challenge. The mean percentage changes in the FEV₁ values calculated from 24 DYARs and 24 PBS control challenges; (■): the initial DYAR; (□): the repeated DYAR; (*): the initial PBS; (×): the repeated PBS; I: initial (baseline) values; ALL: allergen challenge; PBS: phosphate buffered saline; Bars: means ± SEM.
