title: [The effect of sodium nitroprusside on the membrane potential and mechanical tension of the smooth-muscle cells in the rat aorta].
abstract: The rat aorta smooth muscles were contracted and depolarised with high potassium or phenylephrin solution which was followed by a relaxation and repolarisation after sodium nitroprusside administration. The latter effect was decreased az a combined action of phenylephrin and high potassium solution. Nitroprusside seems to act through a cGMP-dependent potassium transient activation of the smooth muscle cell membrane.
