用出生6～7周、体重60～80g的非纯种雄性大白鼠作实验,实验组20只,在乙醚麻醉下用电烙器烧灼右侧下鼻甲前端和鼻中隔粘膜以及鼻孔周围皮肤,经过5～6天,因灼伤处瘢痕挛缩右鼻孔完全闭锁,动物只能用左侧鼻孔呼吸。对照组14只,双侧鼻腔通气通畅。经过6个月,(即大白鼠头颅发育完成时),在乙醚麻醉下切下大白鼠的头颅,经过福尔马林固定,流水冲洗,水煮去净头颅的软组织,用汽油脱脂和强双氧水漂
With 6 to 7 weeks old, weighing 60 ~ 80g of non-purebred male rats for the experiment, the experimental group of 20, under the anesthesia with the electric appliance burning the right inferior turbinate front and nasal septum mucosa and the skin around the nose, after 5 ~ 6 days, due to burn at the scar contracture of the right nostril completely blocked animals can only breathe on the left nostril.
