Modification by L-NG-monomethyl arginine (L-NMMA) of the response to nerve stimulation in isolated dog mesenteric and cerebral arteries.
Treatment with L-NG-monomethyl arginine (L-NMMA) increased the vasoconstriction induced by adrenergic nerve stimulation in perfused dog mesenteric artery segments and suppressed the relaxant response to transmural nerve stimulation in dog cerebral artery strips, the effects of L-NMMA being reversed by L-arginine. The observed changes in nerve function may be associated with the inhibition of synthesis of nitric oxide.
