In order to study the structure of filiform papillae (FP), tissue specimens were taken from the anterior part of the tongues of 8 humans, 8 rats and 8 swine. The formalin-fixed samples were processed routinely for scanning electron microscopy (SEM) and light microscopy. With SEM, FP of human tongue contained 5-12 hairs which were covered with a massive plaque of micro-organisms. FP of rat tongue, on the other hand, contained one papillary projection with smooth surface structure. Colonization of micro-organisms was seen on the anterior part of the body of FP, but not on the hairs. In the cross-section of FP of the rat tongue, the cells of the papilla were close to each other and no micro-organisms were seen within the papillae. On the contrary, the spaces between the squamous epithelial cells of the hairs of human FP contained numerous micro-organisms. The structure of FP of the swine tongue resembled that of the rat tongue. The hairs were smooth, and some micro-organisms were seen on the cell surface of the interpapillary areas. The structure of FP is discussed from the standpoint of different keratinization and colonization of micro-organisms.
为了研究丝状乳头（FP）的结构，从8名人类、8只大鼠和8头猪的舌前部采集了组织标本。将福尔马林固定的样本常规处理以进行扫描电子显微镜（SEM）和光学显微镜检查。通过SEM观察，人类舌部的丝状乳头包含5 - 12根毛发状结构，表面覆盖着大量微生物菌斑。另一方面，大鼠舌部的丝状乳头包含一个表面结构光滑的乳头状突起。在丝状乳头主体的前部可见微生物定植，但在毛发状结构上未见。在大鼠舌部丝状乳头的横切面上，乳头细胞彼此紧密相连，乳头内未见微生物。相反，人类丝状乳头毛发状结构的鳞状上皮细胞之间的间隙含有大量微生物。猪舌部丝状乳头的结构与大鼠舌部相似。毛发状结构光滑，在乳头间区域的细胞表面可见一些微生物。从微生物不同的角化和定植角度对丝状乳头的结构进行了讨论。
