摘　　要：本文应用碱性磷酸酶染色,按立体学方法观测了不同年龄(14岁以下儿童4例,成年人2例,60岁以上老人2例)共8例人脑视皮质有纹区各层毛细血管的密度(各层均取40个数据).结果:成年组视皮质第三层血管网3c亚层(位于皮质第Ⅳc层)毛细血管密度平均为1580.79±47.73mm/mm^3;儿童组为1087.19±44.90mm/mm^3;老年组为619.95±21.39mm/mm^3.经方差分析检验,P<0.01,说明在第三层血管网3c亚层三个年龄组之间具有非常显著性差异.讨论了各年龄组之间视皮质有纹区毛细血管密度差异与机能的关系.The capillary density in 8 human visual cortexes (area striate),4 from children under 14 years old,2 adults and 2 old men over 60,was stereologically studied after alkaline phosphatase staining.The results are as follows:the capillary density of sublayer 3c of the adult is the highest,being 1580.79±47.43mm/mm^3;of the children the next,being 1087.19±44.90mm/mm^3;and of the aged the lowest,being 619.95±21.39mm/mm^3.The analysis of variance (P<0.01) indicated significant difference among the sublayers 3c of different age groups.The relationship between the density of the capillaries in visual cortexes of different age groups and its clinical significance is discussed in this paper.
