Figure 6From: Involvement of nitric oxide (NO) in cough reflex sensitivity between non-sensitized and OVA-sensitized guinea pigsEffect of L-NAME on ENO, between non-sensitized and OVA-sensitized guinea pigs. L-NAME suppressed ENO in both groups dose-dependently. Each individual is presented in open circle, and the mean value is shown as a horizontal bar. n = 6 for each group, *p < 0.05 **p < 0.01Back to article page
