应激是机体在超常刺激状态下,为维持其内环境的稳定,通过丘脑下部-垂体-肾上腺系和植物神经系统,表现出的一种防御性反应。该反应本对机体有益,但反应过度则可引起疾病。目前,对应激性疾病的研究,已有很大进展,但仍有诸多问题需进一步探索。本文仅就有关应激的实验研究加以概述。一、关于应激的生理学研究1.应激对胃的影响在使动物处于各种应激状态下发生应激性溃疡的实验中,可观察胃的各种变化。在猴的溺水实验中发现:进入应激状态后2～3小时,在胃体部粘膜便出现侵蚀性出
Stress is the body’s body in the super-stimulated state, in order to maintain the stability of its internal environment, through the hypothalamus - pituitary - adrenal system and the autonomic nervous system, showed a defensive response. The reaction of the body beneficial, but over-reaction can cause disease. At present, great progress has been made in the study of stress diseases, but there are still many problems to be explored further. This article gives an overview of experimental studies on stress. First, the physiological research on stress 1. The impact of stress on the stomach Animals in a variety of stress-induced stress ulcers in the experiment, we can observe a variety of changes in the stomach. Monkey drowning experiments found: 2 to 3 hours after entering the stress state, gastric mucosa will appear aggressive
