目的 探讨汽车尾气颗粒物(Dieselexhaustparticles,DEP)对小鼠眼表上皮的影响及其相关机制的研究。 方法 40只18-20g成年雄性C57BL/6J小鼠用不同浓度(0、100、1000μg/mL)的DEP悬浊液局部点眼。每天两次(上午9点,下午9点),5ul/眼。在点眼0、14、28天时,分别用俄勒冈绿色葡聚糖(OGD)对小鼠眼表上皮进行染色。以点眼前(0天)小鼠作为对照。处死动物,取眼睑连同眼球组织进行相关检查。HE染色观察角膜上皮组织的形态;PAS染色观察结膜穹窿部杯状细胞的变化。免疫组织化学染色检测眼表CD4阳性细胞的数量,免疫组织荧光染色检测角膜和结膜上皮中ca...Purpose: To explore the effects of diesel exhaust particles (DEP) eye drops on ocular surface structure in mice, and to find a novel animal model for environmental eye disease research Methods: A total of 40 male C57BL/6J mice were used in this study and divided into four groups: blank control group (no treatment, n=4), control group (0.9% saline eye drops, n = 12), low concentration group (100μg...学位:医学硕士院系专业:医学院_眼科学学号:2452014115356
