From: Carbon monoxide affects electrical and contractile activity of rat myocardium
Changes in contractile activity induced by zinc protoporphyrin IX. Effects of ZnPP on contractile activity of working atrial myocardium: (a) representative traces of contraction curves during control conditions and 10 µM ZnPP, (b) maximal effects of ZnPP on contractile force MVC and MVR (n = 5). In part (b) the control values of contractile force, MVC and MVR were considered as 100%. The relative values of these parameters during action of ZnPP are presented in % of control. * - p < 0.05 versus the respective control values.
