Excitatory Agonists and Ca-Permeable Channels in Arterial Smooth Muscle Cellsd. Stimulation with norepinephrine is not accompanied by a depolarization of the cell membrane. The opening of voltage-gated Ca channels by depolarization can therefore be excluded. The existence of receptor-operated Ca channels, which are activated by a direct interaction of the agonist with its re

Myogenic Contraction and Relaxation of Arterial Smooth Muscleproduced by stretch, agonistic stimuli, and high K. in helical strips of canine cerebral artery. Simultaneous measurements of the Ca. signals and tension development were made with a fluorimeter. The autofluorescence, motion artifact, and Ca. buffering action, considered as main disadvantages when f

Sarcoplasmic Reticulum of Mesenteric Arteries Buffers Stimulated Ca2+ Entryall mesenteric arteries to Ca.-free experimental solutions containing EGTA with or without agonist. The agonist-mediated Ca. depletion of the SR markedly reduced the rate and magnitude of the contraction due to Ca. influx through voltage-gated channels. This buffering of Ca. influx by the norepineph
