对27例鼻息肉脂质结合唾液酸（lipid－boundsiaticacid，LSA）和丙二醛（malondialdehyde，MDA）含量进行测定，其X±SD，分别为6．4662±1．2156nmol／mg蛋白和0．6342±0．0271nmol／mg蛋白。与正常鼻粘膜对照具有显著性差异，提示自由基及其导致的细胞结构、功能改变在鼻息肉生成中具有重要作用。
The contents of lipid-boundsiaticacid (LSA) and malondialdehyde (MDA) in 27 cases of nasal polyps were measured, and their X ± SD were 6.4662 ± 1.2156nmol / mg protein and 0 respectively. 6342 ± 0.0271 nmol / mg protein. Significantly different from normal nasal mucosa control, suggesting that free radical and its resulting cell structure, function changes in the formation of nasal polyps play an important role.
