The changes that occur in the distribution and density of the encapsulated endings and Merkel cell-neurite complexes of the lingual gingival and alveolar mucosa of the mandible of kittens from birth to 28 d of age were observed through the use of methylene blue vital staining. The distribution of encapsulated endings showed a tendency to increase over the total area of the mucosae, but Merkel cell-neurite complexes tended to group into bands across the gingivae. While the density of the nerve endings of the former showed a continuous increase over the time period from the day of birth, when they totalled 13/cm2, to the 28th d by which that figure had increased to 144/cm2, the latter showed no such marked increase, totalling only 35/cm2 and 50/cm2, respectively. Further observations were made of the ultrastructures of organized endings in adult cat.
通过使用亚甲蓝活体染色法，观察了从出生到28日龄小猫下颌舌侧牙龈和牙槽黏膜中被囊末梢和默克尔细胞 - 神经突复合体的分布和密度变化。被囊末梢的分布在黏膜总面积上呈增加趋势，但默克尔细胞 - 神经突复合体倾向于在牙龈上形成带状聚集。虽然前者神经末梢的密度从出生时的总计13个/cm²到第28日龄时增加到144个/cm²，在此时间段内持续增加，但后者没有如此明显的增加，分别仅总计35个/cm²和50个/cm²。还对成年猫中有序末梢的超微结构进行了进一步观察。
