Figure 5From: Involvement of nitric oxide (NO) in cough reflex sensitivity between non-sensitized and OVA-sensitized guinea pigsEffect of ONO1714 on cough reflex sensitivity, between non-sensitized and OVA-sensitized guinea pigs. In non-sensitized guinea pigs, there were no antitussive effects of ONO1714 observed, partial antitussive effect of ONO1714 on cough reflex sensitivity to the 10-4 M capsaicin solution was observed in only OVA-sensitized guinea pigs. Each individual is presented in open circle, and the mean value is shown as a horizontal bar. n = 6 for each group, **p < 0.01Back to article page
