  1. Kinetic parameters of the relaxation processes of the skinned taenia cecum and carotid artery of the guinea pig in Rigor solution in the presence or absence of CC-D. In addition to parameters listed on Table 2, τrigor-attach and τrigor-detach represent time constants of attaching and detaching rigor-bridge in the rigor conditions, respectively. Values represent mean ± S.E.M. (taenia cecum n = 8, carotid artery n = 8). *1P = 0.218. *2P = 0.059
