Direct effects of ANP and Ex-4 on smooth muscles of isolated mouse bronchi, including nonresponders. Concentration-relaxation curves induced by ANP and EX-4 on bronchial smooth muscle tissue. Relaxation values are expressed as a percentage of the relaxation seen with a maximally effective concentration of SNP (0.1 mM) added at the end of the experiment. Data are shown as means ± SEM. A, The effect of ANP on tissue from COPD compared to healthy mice. B, The effect of EX-4 on COPD mice compared to healthy mice. C, Example of myograph signals from tissue sections responding to ANP and D, not responding to ANP, but to SNP.
