测量毛细血管密度，并不能正确反映组织的血管容量分布，文内采用作者在Ｅｌｉａｓ毛细血管体积密度概念的基础上，研究的一种单位体积组织中毛细血管容积（比容积）测量法。采用３０例（６０侧）６个月胎儿至６岁儿童新鲜尸体大脑，用碱性磷酸酶（ＡＫＰ）染色，在光镜下观察毛细血管分布，显微放大照相，自动彩扩机扩印照片，游标卡尺测量并计算海马皮质毛细血管“比容积”。结果表明，四个年龄组的左右侧毛细血管比容积，均无明显差异（Ｐ＞０．０５），海马皮质三个区域之间的毛细血管比容积，有明显差异（０．０１＜ＰＭ０．０５），ＣＡ１区和下托区＞ＣＡ４区和齿状回＞ＣＡ２和ＣＡ３区。比较各区域海马皮质的三层机构毛细血管比容积，也有明显差异（０．０１＜Ｐ＜０．０５），多形细胞层＞分子层＞锥体细胞层或颗粒层。海马皮质厚度和毛细血管比容积，均随年龄增大而增加。
Measurement of capillary density does not accurately reflect the distribution of vascular capacity in the tissue. The text uses a measurement of capillary volume (volume) in a unit volume of tissue based on the concept of Elias capillary bulk density. Fresh cadaver brains from 30 fetuses (60 sides), 6 months old to 6 years old, were stained with alkaline phosphatase (AKP). Capillary distribution was observed under light microscope. Micro-magnification photography, The hippocampal cortical capillary “specific volume” was measured and calculated. The results showed that there was no significant difference in the specific volume of the left and right capillaries in the four age groups (P> 0.05). The capillary volume between the three regions of the hippocampus was significantly different (0.01 CA4 area and dentate back> CA2 and CA3 area. There was also a significant difference (0.01
molecular layer> pyramidal cell layer or granular layer. Hippocampal cortical thickness and capillary volume, both increased with age.
