The reticular fibers of the capillary sheath and splenic cord were studied in the pig spleen by transmission electron microscopy to reveal their components and the presence of sialic acid in the amorphous ground substance. Collagen fibrils, elastic fibers, microfibrils, nerve fibers and smooth muscle cells were observed in the reticular fibers of the splenic cord, while only microfibrils were recognized in the reticular fibers of the capillary sheath. The binding of LFA lectin to the splenic cord was stronger than the capillary sheath. These findings may suggest that the reticular fibers of the splenic cord include numerous functional elements and perform an important role during contraction or dilation of the spleen. On the other hand, it seems to be reasonable to term the capillary sheath as "capillary basement membranous reticular tissue", since the reticular fiber of the capillary sheath resembles the basement membrane of the capillary in its components.
通过透射电子显微镜对猪脾脏中毛细血管鞘和脾索的网状纤维进行研究，以揭示其组成成分以及无定形基质中唾液酸的存在情况。在脾索的网状纤维中观察到了胶原纤维、弹性纤维、微原纤维、神经纤维和平滑肌细胞，而在毛细血管鞘的网状纤维中仅识别出微原纤维。LFA凝集素与脾索的结合强于毛细血管鞘。这些发现可能表明，脾索的网状纤维包含众多功能元件，在脾脏收缩或扩张过程中发挥重要作用。另一方面，将毛细血管鞘称为“毛细血管基底膜网状组织”似乎是合理的，因为毛细血管鞘的网状纤维在其组成成分上类似于毛细血管的基底膜。
