The effect of atrial natriuretic factor (ANF) on [3H]norepinephrine release evoked by sympathetic nerve stimulation was examined in the isolated perfused rat mesenteric arteries. ANF (1 nM to 0.1 microM) caused a dose-dependent inhibition of [3H]norepinephrine release during nerve stimulation. The present result indicates that ANF inhibits noradrenergic neurotransmission in the rat mesenteric arteries through a prejunctional mechanism. This prejunctional effect of ANF may in part contribute to its vasodilation action.
在离体灌注的大鼠肠系膜动脉中,研究了心房利钠因子(ANF)对交感神经刺激诱发的[3H]去甲肾上腺素释放的影响。ANF(1 nM至0.1 microM)在神经刺激期间引起[3H]去甲肾上腺素释放的剂量依赖性抑制。目前的结果表明,ANF通过节前机制抑制大鼠肠系膜动脉中的去甲肾上腺素能神经传递。ANF的这种节前效应可能部分有助于其血管舒张作用。
