消化道粘膜血流是维持细胞代谢的重要因素,与粘膜病变的产生及治疗效果密切相关。粘膜微循环既受应激等全身性因素通过神经体液性因子的影响,也受酒精、NSAID 的直接作用。因此,本文对不同层次调节粘膜微循环的神经因子、激素及化学介质等加以讨论。一、神经系统的作用1.交感神经系统很久以来,人们就注意到植物神经系统是全身性应激状态对胃粘膜微循环起影响的途径。胃粘膜内的毛细血管膜 Gastrointestinal mucosal blood flow is an important factor in maintaining cell metabolism, and mucosal lesions and the treatment effect is closely related. Mucosal microcirculation both by stress and other systemic factors through the influence of neurohumoral factors, but also by the direct effect of alcohol, NSAID. Therefore, this article discusses the different levels of regulation of mucosal microcirculation of nerve factors, hormones and chemical media to be discussed. First, the role of the nervous system 1. Sympathetic nervous system For a long time, people have noticed that the autonomic nervous system is the systemic stress state of gastric mucosal microcirculation affect the way. Capillary membrane in the gastric mucosa
