2. Figure 1
Effects of aerosolized isoproterenol and vasoactive intestinal peptide (VIP) on histamine induced bronchoconstriction in two human subjects: subject 1, asymptomatic asthmatic (•, ○) and subject 2, nonasthmatic (▲,7). A. Two control histamine challenges administered at 5 h intervals. B, C and D-effects of isoproterenol and VIP on responses to histamine challenge conducted 5 h apart. Each treatment was administered on a separate day. BL = baseline; V = vehicle; cumulative dose of histamine = sum (histamine concentration in mg/ml × number of breaths taken).
