人舌前部味觉功能和菌状乳头的定量研究

Quantitative studies of taste and fungiform papillae on the anterior human tongue

目的全面、客观、准确地评价舌前２／３的味觉功能，并能定量研究菌状乳头的密度。方法采用局部封闭式液池（ａｓｐａｔｉａｌｃｌｏｓｅｄｆｌｏｗｃｈａｍｂｅｒ）检测６０名健康成人舌前部味觉功能和菌状乳头的形态和数量。结果①正常成人舌前部菌状乳头密度、味觉发现阈和强度比较能力在男女之间、左右之间、种族之间差异无显著性；②不同个体之间在菌状乳头密度和味觉功能上差异有显著性；③菌状乳头密度是决定舌前部味觉功能的重要因素，并与味觉功能呈明显的正相关；④局部封闭式液池检测舌前部味觉功能可以达到本研究的目的。结论本研究方法对确定味觉病变的性质和舌神经损伤及修复后味觉功能以及菌状乳头的动态研究。

? Objective To study qantitatively in the taste and fungiform papillae on the anterior human tongue. Methods Sixty normal adults were evaluated the spatial taste and the fungiform papilla density at spatiallymatched sides on the right and left sides of the anterior tongue. The taste stimulative solutions were delivered to a spatiallymatched flow chamber attached to the surface of the right or left anterior tongue. Results (1) There is no statistical difference in number of the fungiform papillae, taste threshold and magnitude matching between right/left, male/female and races; (2) There is a significant difference in fungiform papilla density and taste functions in different individuals; (3) The fungiform papilla density is the key to taste function on 2/3 anterior of tongue, and is positively correlated to it; (4) The use of a spatiallymatched flow chamber is a valid test system for overall, objective and accurate evaluating taste on the 2/3 anterior of tongue, and can be used to study quantitatively the fungiform papilla density. Conclusion It is of clinical significance for the diagnosis of taste diseases and the dynamic studies of the taste and the fungiform papillae after lingual nerve injury and repair.【
