任何物理性刺激(机械的、温热等)能引起变应性改变,且首先是荨麻疹。在所谓的胆硷能荨麻疹的发病中有些人认为是大量(超过正常水平)乙酰胆硷的释放,而有些人认为,此时胆硷脂酶的活性降低。乙酰胆硷是胆硷能神经系统的介质,在一系列神经突触中执行传递兴奋的功能,也有调节组织功能状态的作用。有人研究乙酰胆硷在测定变应性的功能友现中起重要作用。作者观察了22例不同类型的荨 Any physical stimulus (mechanical, warm, etc.) can cause allergic changes, and above all, urticaria. In the so-called cholinergic urticaria, some people think that the release of acetylcholine (more than normal levels), while some people think that cholinesterase activity decreased. Acetylcholine, the mediator of the cholinergic nervous system, performs the function of transmitting excitability in a series of neuronal synapses and also plays a role in regulating the functional state of the tissue. Acetylcholine has been found to play an important role in determining the function of allergy. The authors looked at 22 different types of nectar
