脑在局部缺血的情况下会受到非均匀、选择性地损害。有关对机体内部调节起着特殊作用的丘脑下部的损伤研究,对于神经外科临床是很有意义的。当丘脑、基底神径节和皮层因微循环紊乱血液不通畅而发生广泛变化时,我们注意到丘脑下部却完整无恙。血液停止后6分钟向狗脑血管灌注墨汁的脑额状切片显示丘脑部位出现白斑,表明毛细血管网几乎完全不通,但丘脑下部的毛细血管网充满墨汁,说明血流畅通,丘脑和丘脑下部间呈现出明显的分界。作者研究了血流停止不同时期后的丘脑下部的
The brain is subject to non-uniform and selective damage in the case of ischemia. Research on damage to the lower part of the thalamus, which has a special effect on the regulation of the body’s internal organs, is clinically significant for neurosurgery. When the thalamus, basal ganglia and cortical masses undergo extensive changes due to unnoticed microcirculation disturbances, we noticed that the hypothalamus was intact. Six minutes after the cessation of blood flow to the cerebrovascular perfusion ink of the brain, forehead-like sections of the brain showed white spots on the thalamus, indicating almost complete failure of the capillary network, but the capillary network of the hypothalamus is filled with ink, indicating smooth blood flow, Showing a clear boundary. The authors studied the hypothalamus after blood flow stopped at different stages
