正常儿童和成人的鼻粘膜含有大量柱状上皮细胞、一些杯状细胞、偶见肥大细胞(或嗜碱细胞),其他细胞(嗜酸细胞、嗜中性细胞、细菌)则很少或完全没有。在鼻部变态反应时,鼻粘膜中嗜酸细胞和肥大细胞(嗜碱细胞)增多;而在细菌感染时,嗜中性细胞和细菌常增多。变态反应学书籍中一般记述大多数新生儿鼻粘膜中嗜酸细胞增多,因此认为在年龄小于6个月的婴儿,进行鼻细胞学检查其诊断价值不大。作者等应用可弯的塑料鼻拭子采取鼻粘膜,研究了健康婴儿鼻粘膜的细胞学。研究对象为27名2天至12月的婴儿,其中22名为健康婴儿,5
Nasal mucosa of normal children and adults contain a large number of columnar epithelial cells, some goblet cells, occasionally mast cells (or basophils), and other cells (eosinophils, neutrophils, bacteria) are little or no. In allergic rhinitis, there is an increase in eosinophils and mast cells (basophils) in the nasal mucosa, while neutrophils and bacteria often increase in bacterial infections. Allergology books generally describe most newborns nasal mucosa increased eosinophilia, therefore considered less than 6 months of age, nasal examination of nasopharyngeal diagnosis of little value. The authors applied a bendable plastic nasal swab to take a nasal mucosa and studied the cytology of nasal mucosa in healthy infants. The study population was 27 infants from 2 days to December, 22 of whom were healthy infants
