From: Hyperresponsiveness to inhaled but not intravenous methacholine during acute respiratory syncytial virus infection in mice

Figure 7

Airway resistance in response to iv MCh challenge in adult and weanling mice at 7 d post infection. RSV infected mice (closed symbols) did not demonstrate increased responsiveness to any concentration of iv MCh compared to controls (open symbols) at either age. Raw returned to baseline levels following atropine administration. RSV-infected weanling mice had slightly elevated Raw throughout the iv challenge, although this was due to their smaller size rather than altered responsiveness.
