为了研究鼻咽部神经末梢的接受器,作者用Gairn氏神经末梢氯化金染色法检查了15例鼻咽粘膜。病人8女7男,年龄为2～48岁。材料取自增殖体切除术或为排除新生物而作的鼻咽腔活体。取新鲜的鼻咽粘膜小片,浸入25％蚁酸溶液(1份蚁酸、3份滤过的柠檬汁混合而成),约10分钟取出放于干净的滤纸上吸去多余的水份;然后浸于1％氯化金溶液中15分钟,又移放于滤纸上;再一次浸入25％蚁酸并移放滤纸上;最后 In order to study the receptors of nasopharyngeal nerve endings, the authors examined 15 nasopharyngeal mucosa with Gairn’s nerve endings with gold chloride staining. 8 women and 7 men, aged 2 to 48 years old. The material is taken from a vegetative part of the nasopharyngeal cavity for excision of neoplasms. Take fresh pieces of nasopharyngeal mucosa, immersed in 25% formic acid solution (1 part of formic acid, 3 parts of filtered lemon juice mixed), about 10 minutes out on a clean filter paper to absorb excess water; then Immersed in 1% gold chloride solution for 15 minutes, and then transferred to the filter paper; once again immersed in 25% formic acid and transferred to the filter paper; finally
