作者试图用形态学方法,利用Wistar鼠烫伤后形成的呼吸窘迫综合征(ARDS)作实验,对脑部进行定向破坏或脑内、脑室内注入特殊的微量药物,以观察其对ARDS的影响,从而证实在ARDS的发生中,中枢神经系统的重要病理生理学作用。动物分成若干组。组Ⅰ:定向电极的阳极直流电置于下丘脑前核或后核。组Ⅱ:脑室内注入微量酚苄明 The author attempts to use Morphology method to make use of ARDS which is formed after scald in Wistar rats to conduct experiments on the brain to make targeted damage to the brain or to inject special trace drugs into the brain and brain to observe its effect on ARDS, Thus confirming the occurrence of ARDS, the central nervous system, an important pathophysiological role. The animals are divided into groups. Group I: The anodic direct current of the directional electrode is placed in the anterior or posterior nucleus of the hypothalamus. Group Ⅱ: intraventricular injection of trace amount of phenoxybenzamine
