Figure 2From: Modulation of cough response by sensory inputs from the nose - role of trigeminal TRPA1 versus TRPM8 channelsUpper panel represents the changes of cough threshold - parameter C2. As it could be seen C2 values are not significantly different when comparing data obtained after nasal saline, vehicle, AITC and cinnamaledyde. Cumulative and total cough response obtained during the cough tests after nasal AITC and cinnamaldehyde do not differ from saline and vehicle values (lower panel) (all p>0.05).Back to article page
