每隔 24 小时对新生至 72 小时龄比格犬幼犬的端脑微血管进行超微结构研究。将来自生发基质的微脉管系统的形态测量与来自边缘区大脑皮层的微脉管系统的形态测量进行比较。在研究期间，这两个部位的微血管的内皮细胞壁相似，但基质微血管的管腔明显大于对照皮质微血管的管腔。具有大管腔的基质微血管的比例随着时间的推移逐渐磨损。基质微血管的管腔值（面积）及其分布与皮质的值（面积）及其分布相似。皮质微血管的形态测量相对静态。数据表明，比格犬幼犬生发基质的微脉管系统在出生后不久发生了积极的改变。
The microvessels of the telencephalons of Beagle puppies between newborn and 72 hours of age were investigated ultrastructurally at 24‐hour intervals. The morphometry of the microvasculature from the germinal matrix was compared with that of the microvasculature from the borderzone cerebral cortex. The endothelial cell walls of the microvessels from these two sites were similar during the study period, but the lumina of the matrical microvessels were significantly larger than the lumina of the control cortical microvessels. The proportion of matrical microvessels with large lumina undergoes progressive attrition with time. The values (areas) for the lumina of the matrical microvessels, and their distribution, come to resemble those of the cortex. The morphometry of the cortical microvasculature is comparatively static. The data suggest that there is an active modification in the microvasculature of the germinal matrix of the Beagle puppy in the immediate postnatal period.
