Typical tension traces of relaxation process. Relaxation process after Ca²⁺ removals of β-escin skinned (cell membrane permeabilized) taenia cecum (A) and carotid artery (B) preparations in the Relaxing solution (with CTP) in the presence or absence of CC-D at 10 μM, 30.0 ± 1.0 ℃. Ordinate: Relative force normalized with the maximal tension level induced by 10^–5.0 M Ca²⁺ promptly before the Ca²⁺ removal. Abscissa: Time in seconds after the Ca²⁺ removal
