Electro- and Pharmacomechanical Coupling in the Smooth Muscle Cells of the Rabbit Ear Artery

  • Published 2003


A ~ S T R A C T A contraction of the rabbit ear ar tery can be induced by depola r iz ing the cells with a K-rich solution if Ca is present . 10 -9-10 -8 M no rad rena l ine and 10 -s10 -7 M his tamine cause a contraction of this tissue without modify ing the m e m brane potent ial . If the his tamine concent ra t ion exceeds 10 -~ M some depolar iza t ion… (More)
