Table 1: Maximum response to metacholine obtained in the presence of A. millefolium, 10 nM atropine, and saline in the three sets of experiments. Data are presented as mean ± SEM. Group 1, experiments on non incubated tracheal chains (n = 6); Group 2, experiments on tracheal chains incubated with propranolol and chlorpheniramine (n = 9); Group 3, experiments on tracheal chains incubated with propranolol (n = 7). Statistical signifi cance for the difference in the data between saline and other solutions, *: P < 0.05, There was no statistical difference in maximum response between the three groups
