Investigation was performed on healthy and inflamed human gingivae. In the healthy mucosa lymphatic vessels generally appeared as flattened channels with a reduced lumen. Only in very inflamed tissue were some more evident vessels with a distended wall detectable. Ultrastructurally, most of the vessels had the characteristics of capillaries and they were delimited by a thin and irregular endothelial wall with large intercellular spaces. These observations indicate that in the gingival tissues, which are continuously exposed to inflammatory agents and need a really efficient draining system, the pathway of interstitial exudation and cell migration may include both the lymphatic vessel system and the intercellular spaces of the permeable junctional epithelium.
对健康和发炎的人类牙龈进行了研究。在健康的黏膜中，淋巴管通常呈现为管腔缩小的扁平通道。只有在炎症非常严重的组织中，才能检测到一些管壁扩张且更明显的血管。在超微结构上，大多数血管具有毛细血管的特征，它们由一层薄且不规则的内皮细胞壁界定，细胞间隙较大。这些观察结果表明，在持续暴露于炎症介质且需要真正高效引流系统的牙龈组织中，间质渗出和细胞迁移的途径可能既包括淋巴管系统，也包括可渗透连接上皮的细胞间隙。
