存在于中枢神经系统的精氨酸加压素(Arginine Vasopressin AVP)可能作为神经递质或调质参与脑组织水代谢、脑血管舒缩以及学习与记忆等过程。临床上发现脑梗塞和脑出血病人脑脊液中AVP含量增加。然而,关于脑脊液中AVP含量变化与脑血管病发病后时间以及病变分布的关系未见报道。本工作使用放射免疫分析技术测定了 Arginine Vasopressin (AVP), which is found in the central nervous system, may serve as a neurotransmitter or mediate the process of water metabolism, cerebral vasomotion and learning and memory in brain tissues. Clinically found that cerebral infarction and cerebral hemorrhage in patients with cerebrospinal fluid AVP content increased. However, there is no report on the relationship between the changes of AVP in cerebrospinal fluid and the time of onset of cerebrovascular disease and the distribution of lesions. This work has been done using radioimmunoassay techniques
