TRH在蓝斑复合核对血压和心率的影响及其机制
Effects of TRH at Locus Caeruleus Complex Area on Blood Pressure and Heart Rate and Its Mechanism
摘要
Abstract
Objective To research the effect of TRH at locus caeruleus complex area (Lc-Sc) on blood pressure and heart rate and its mechanism.Methods The experiments were carried out on 33 anaesthetized,paralyzed and artificially ventilated rabbits.Intranuclear microinjection was adopted in this experiment.Results It was found microinjection of TRH into Lc-Sc induced a marked elevation of blood pressure and increased in heart rate.The above-mentioned effects of TRH could be blocked by preinjection α1 or β receptor-antagonist in the nucleus tractus solitarii(NTS).Conclusion TRH can excite cardiovascular activities in the Lc-Sc and this effects may be mediated by α1 or β receptors in NTS.关键词
