Abstract

Intrapericardial administration of 5-hydroxytryptamine (5-HT) induced reflex effects consisting in an inhibition of renal sympathetic nerve activity (RSNA), bradycardia and a fall in blood pressure. Nicotine caused the same reflex effects as 5-HT. The reflex effects of both 5-HT and nicotine were abolished by vagotomy. MDL 72222, an antagonist at 5-HT M-receptors, abolished or attenuated the decreases in RSNA, heart rate and blood pressure induced by 5-HT, leaving the reflex effects of nicotine unchanged. In the absence of MDL 72222 the reflex bradycardia partially concealed a positive chronotropic response to 5-HT. After blockade of the bradycardia response by MDL 72222, 5-HT elicited a significant tachycardia, which was not altered by propranolol and phentolamine, but was prevented by phenoxybenzamine. 5-HT probably reaches the sinoatrial node and activates 5-HT receptors that mediate directly the increase in heart rate. The nicotine receptor antagonist hexamethonium selectively abolished or attenuated the reflex effects of nicotine without interfering with those of 5-HT. We conclude that 5-HT and nicotine elicit similar reflex effects in epicardial vagal nerve endings by stimulation of M-receptors or nicotine receptors, respectively.

摘要

在心包内给予5-羟色胺(5-HT)可诱发反射效应,包括抑制肾交感神经活动(RSNA)、心动过缓和血压下降。尼古丁产生与5-HT相同的反射效应。5-HT和尼古丁的反射效应均被迷走神经切断术消除。5-HT M受体拮抗剂MDL 72222消除或减弱了5-HT引起的RSNA、心率和血压下降,而尼古丁的反射效应未改变。在没有MDL 72222的情况下,反射性心动过缓部分掩盖了对5-HT的正性变时反应。在用MDL 72222阻断心动过缓反应后,5-HT引起显著的心动过速,普萘洛尔和酚妥拉明对此无改变,但苯氧苄胺可阻止。5-HT可能到达窦房结并激活直接介导心率增加的5-HT受体。尼古丁受体拮抗剂六甲铵选择性地消除或减弱了尼古丁的反射效应,而不干扰5-HT的反射效应。我们得出结论,5-HT和尼古丁分别通过刺激M受体或尼古丁受体,在心外膜迷走神经末梢引发相似的反射效应。
