Data are expressed in gram (g) of maximal tension generated for the highest agonist and antagonist concentration (10−4 M). Rings #1 and #2 were cut prior to cryopreservation. Rings #3 through #7 were sectioned starting from the free end of the vessel toward the cannula site. Ring#6 was cut from the middleice covered section of the artery.
