[Action of noradrenaline and acetylcholine on the contractile activity of the gastric arteries].

The effects of norepinephrine and acetylcholine on smooth muscle cells of isolated strips of gastric arteries were studied. The gastric arteries revealed small sensitivity to acetylcholine. The norepinephrine effects on smooth muscle cells can be realized through electrogenic and pharmacomechanical activation. The adrenergic control of gastric arteries is fulfilled mainly with alpha-adrenoreceptors participation.
