近年来有人发现,动脉压力感受器的冲动发放以及压力感受器引起的反射,受灌注液中的钠、钾、钙、镁等离子浓度变化的影响。因而提出所谓压力感受器的离子敏感性概念。本文就该问题的提出、基本实验结果及其作用机制等问题的研究动态作了简要介绍。 In recent years, it has been found that the impulse of arterial baroreceptors and reflex caused by baroreceptors are affected by plasma sodium, potassium, calcium and magnesium concentrations in perfusate. Thus put forward the so-called baroreceptor ion sensitivity concept. This article gives a brief introduction of the research trends on the issues raised, the basic experimental results and their mechanism of action.
