中枢神经系统内存在着多种神经介质系统,如乙酰胆碱、去甲肾上腺素、多巴胺、5-羟色胺、r-氨基丁酸、内啡素和P物质等。一种神经介质的改变,可影响另一种或几种神经介质的变化,而机体内某种行为和功能的变化,又常涉及几种神经介质的改变。目前了解,在中枢神经系统中存在着几种相互对立又彼此联系的神经介质系统,如5-羟色胺与去甲肾上腺素、乙酰胆碱与多巴胺、5-羟色胺与组织胺等,其相互关系的失调,可能是产生某种疾病的病理生理学基础。因此,在研究某种生理功能和疾
Central nervous system exists in a variety of neurotransmitter systems, such as acetylcholine, norepinephrine, dopamine, serotonin, r-aminobutyric acid, endorphins and substance P and so on. A change in a neuro-mediator can affect changes in one or more other neuro-mediators, and changes in some of the behaviors and functions in the body often involve changes in several neurotransmitters. Currently, there are several neurotransmitter systems in the central nervous system that are antagonistic and related to each other, such as serotonin and norepinephrine, acetylcholine and dopamine, 5-hydroxytryptamine and histamine, and their related disorders, It may be the pathophysiology of some disease. Therefore, in the study of a certain physiological function and disease
