粘膜调整剂卡波半胱氨酸(carbocysteine)已用于治疗呼吸道感染,加速粘膜分泌液的排除。为评价其对鼻、鼻窦炎粘膜分泌的影响,使二组豚鼠暴露于甲醛气以诱发鼻、鼻窦炎。然后一组口服卡波半胱氨酸200mg/kg,连续6日。另一组不用药以做对照。第7日处死动物,取鼻、鼻窦粘膜,行病理组织学及扫描电 The mucosal regulator carbocysteine ​​has been used to treat respiratory infections and expedites the elimination of mucosal secretions. In order to assess its impact on mucosal secretion of nasal and sinusitis, two groups of guinea pigs were exposed to formaldehyde gas to induce nasal and sinusitis. Then a group of oral carbocystine 200mg / kg, for 6 days. The other group did not use drugs for comparison. Animals were sacrificed on the seventh day, nasal and sinus mucosa, histopathology and scanning scan
