应用甲醛碳素墨水灌注,按立体学方法测量并分析5例儿童(3～11岁)小脑皮质及髓质的毛细血管密度.结果如下:皮质深层(包括蒲氏层和颗粒层)毛细血管密度最高,为1137.25±204.95mm/mm~3,皮质浅层(分子层)次之,为647,68±153.18mm/mm~3,,髓质最低,为493.81±126.78mm/mm~3,经统计学分析表明三者具有显著性差异(P<0.01;而对于同一层次,小脑各区间差异不显著(P>0.05).文内还讨论了毛细血管密度与小脑细胞构筑的关系. The use of formaldehyde carbon ink perfusion, according to the stereological method to measure and analyze the 5 cases of children (3 to 11 years old) of the cerebellar cortex and medulla capillary density. The results are as follows: cortical deep layer (including the layer of Beaufort and granular) capillary density The highest was 1137.25 ± 204.95mm / mm ~ 3, followed by the cortex superficial layer (molecular layer), followed by 647,68 ± 153.18mm / mm ~ 3, the lowest medullary mass was 493.81 ± 126.78mm / mm ~ Statistical analysis showed that there was a significant difference between the three groups (P <0.01; while for the same level, there was no significant difference between the cerebellum regions (P> 0.05) .Changes of capillary density and cerebellar cells were also discussed.
