摘要

At concentrations ranged from 0.1 nM to 1 mu M, trilinolein concentration-dependently relaxed the phenylephrine-induced constriction of isolated rat aorta. Concentration-response curves for the interaction between trilinolein and phenylephrine showed that trilinolein was unlikely a competitive antagonist of phenylephrine. The vasorelaxant effect of trilinolein was dependent on the presence of intact endothelium. Both N-G-nitro-L-arginine methyl ester and methylene blue antagonized this vasorelaxant effect. L-arginine partially reversed the effect of L-NAME on trilinolein. Linoleic acid had no vasorelaxant effect. We concluded that trilinolein is an endothelium dependent vasorelaxant and the underlying mechanism could be a stimulation of the nitric oxide and cyclic GMP pathway. [References: 14]
