Complete cerebral ischemia was produced in totally isolated dog heads, perfused from a donor dog. The temperature of the isolated brain was kept constant before, during and after the complete ischaemia, at either 37 degrees C or 32 degrees C. At a brain temperature of 37 degrees C electrocortical potentials were found to reappear spontaneously as long as complete ischaemia did not exceed 50 min. In canine brains kept at a temperature of 32 degrees C no reappearance of spontaneous electrical activity occurred if ischaemia exceeded 100 min.
在完全隔离的狗头部制造完全性脑缺血,这些头部由供体狗进行灌注。在完全缺血之前、期间和之后,将隔离脑的温度保持恒定,分别为37摄氏度或32摄氏度。在脑温为37摄氏度时,只要完全缺血不超过50分钟,就会发现皮层电位自发再现。在保持于32摄氏度的犬脑中,如果缺血超过100分钟,则不会出现自发电活动的再现。
