Figure 3: (a) A cumulative dose-response curve for Adrenaline (AD)treatments with lidocaine. (b) A cumulative dose-response curve forNoradrenaline (NA) treatments with lidocaine. (c) Contractileresponses of non-lipopolysaccharide-treated aortic rings to AD at 0h, with (squares) or without (circles) lidocaine treatment. (d)Contractile responses of non-lipopolysaccharide-treated aortic ringsto NA at 0 h, with (squares) or without (circles) lidocaine treatment.Data are expressed as mean ± standard error (5 animals per group).Values that do not share the same superscript at each time point aresignificantly different (Mann-Whitney U test, P<0.05).
