Figure 5From: Does unrestrained single-chamber plethysmography provide a valid assessment of airway responsiveness in allergic BALB/c mice? Mean ± SD of sneezes(A)and nose rubs (B) after various concentrations of intranasal histamine in mice. The mice were sensitized with OVA and challenged with single-dose OVA challenge (OVA-1D, blue color line) or three-dose OVA challenge (OVA-3D, red color line). *P < 0.05 compared with control (green color line). **P < 0.05 compared with OVA-1D.Back to article page
