To make the ischemic effect on spinal cord clear, different vessels of the cord of 38 dogs, in 5 groups, were electrically cauterized individually or in combination. The animals in each group were sacrificed in due time periods, and the pathology of corresponding segment of each cord was observed grossly and under electron as well as light microscopes. The findings were described in this paper. As a consequence, the dogs in each group manifested paraplegia varying in degrees. However, dogs with the anterior cord artery and unilateral radicular artery, or both the anterior and posterior cord arteries cauterized developed irreversible, complete paraplegia. Cauterization of the anterior cord artery, or the posterior cord artery and unilateral radicular artery, or the radicular artery on both sides, gave rise to reversible, incomplete paraplegia. Anatomy of vessels of the spinal cord of other 9 dogs were dissected and studied. Their presence and distribution were cited and referred to the discussion about the effect of ischemia induced by electrifying them individually or in combination.
为明确脊髓的缺血效应,将38只狗分为5组,分别对其脊髓的不同血管进行单独或联合电灼。每组动物在适当时间段内处死,对每段脊髓相应节段进行大体观察以及电子显微镜和光学显微镜下的病理学观察。本文描述了研究结果。结果显示,每组狗均出现了不同程度的截瘫。然而,前脊髓动脉和单侧神经根动脉或前后脊髓动脉均被电灼的狗发生了不可逆的完全性截瘫。前脊髓动脉、后脊髓动脉和单侧神经根动脉或双侧神经根动脉被电灼导致可逆性不完全性截瘫。解剖并研究了另外9只狗的脊髓血管。引用了它们的存在和分布情况,并用于讨论单独或联合电刺激引起的缺血效应。
