为了解鼻内翻性乳头瘤(nasal inverted papilloma)内的肥大细胞和嗜酸性粒细胞与鼻粘膜上皮细胞增殖的关系,选择5例男性(平均54.4岁)鼻内翻性乳头瘤患者为对象进行研究。同时选择5例男性(平均42.6岁)慢性鼻窦炎合并肥厚性鼻炎排除变态反应的患者作为对照。将手术获取的鼻肿瘤组织和上颌窦粘膜及下鼻甲粘膜标本,各分为两份,一份用Mota固定液(Mota氏醋酸铅液,MLA)固定,另一份行10％福尔 In order to understand the relationship between mast cells and eosinophil proliferation in nasal inverted papilloma and nasal mucosal epithelial cells, five male (mean 54.4 years) patients with nasal inverted papilloma were selected as subjects the study. At the same time, five men (mean 42.6 years) with chronic rhinosinusitis and hypertrophic rhinitis were selected to exclude allergic patients as a control. Nasal neoplasms and maxillary sinus mucosa and inferior turbinate mucosa obtained in the surgery were divided into two groups, one was fixed with Mota fixation solution (Mota’s lead acetate solution, MLA) and the other was treated with 10%
