Abstract

By means of anatomical and histological methods and a morphometric analysis, microcirculatory vessels of the reticular ganglionary layer in the dog eye were studied within Scharrer's zone with special reference to the reciprocal arrangement of the vessels and opticoganglionary cells under normal conditions and at overloadings (9 units for 10 min) applied in the direction head--pelvis (I series) and pelvis--head (II series). It was stated that immediately after the overloading in the direction head--pelvis the microcirculatory vessels grew narrow and the area of the vascular-neurocytic contacts decreased. At the overloading applied in the direction pelvis--head, the diameter of the vascular-neurocytic contacts sharply increased. In both series of the experiment the vessels became deformed and twisted and the vascular wall permeability was disturbed.

摘要

通过解剖学和组织学方法以及形态计量分析,对犬眼施勒尔区内网状神经节层的微循环血管进行了研究,特别关注正常条件下以及在头-骨盆方向(I系列)和骨盆-头方向(II系列)施加过载(9单位,持续10分钟)时血管与视神经节细胞的相互排列。结果表明,在头-骨盆方向施加过载后,微循环血管立即变窄,血管-神经细胞接触面积减小。在骨盆-头方向施加过载时,血管-神经细胞接触直径急剧增加。在两个实验系列中,血管都发生了变形和扭曲,血管壁通透性也受到了干扰。
