muscle
• the pCa force curve is shifted left by 0.3 pCa units in alpha-toxin permeabilized ileal smooth muscle but not in aorta smooth muscle
|
• 8-Br-cGMP-induced muscle relaxation is impaired in alpha-toxin permeabilized ileal smooth muscle precontracted with pCA 6.3
• however, the array of myosin filaments in longitudinal muscle from the ileum is normal
