    • The invention provides methods and materials related to the diagnosis of eosinophil degranulating conditions. Specifically, the invention provides methods and materials that involve visual types of analysis (e.g., microscopic analysis) that are used to determine the presence or absence of a horseshoe-shaped eosinophil granule structure within a mucus sample collected from a mammal. The presence of a horseshoe-shaped eosinophil granule structure within a patient's mucus indicates that the patient has an eosinophil degranulating condition. In addition, the invention provides methods and materials that involve immunological types of analysis (e.g., immunoassays) that are used to determine if a patient's mucus contains a tissue-damaging amount of eosinophil granule content that is outside the eosinophil granule and within the mucus. Like the presence of a horseshoe-shaped eosinophil granule structure, the presence of a tissue-damaging amount of eosinophil granule content outside the eosinophil granule and within the mucus indicates that the patient has an eosinophil degranulating condition. Further, the invention provides diagnostic kits that can be used to determine whether or not a patient has an eosinophil degranulating condition.
    • 本发明提供了与嗜酸性粒细胞脱粒条件的诊断相关的方法和材料。 具体地说,本发明提供了涉及用于确定从哺乳动物收集的粘液样品内是否存在马蹄形嗜酸性粒细胞结构的分析的视觉类型(例如,微观分析)的方法和材料。 患者粘液中马蹄形嗜酸粒细胞颗粒结构的存在表明患者具有嗜酸性粒细胞脱颗粒状态。 此外,本发明提供了涉及用于确定患者的粘液是否包含嗜酸性粒细胞颗粒外部和粘液内的组织损伤量的嗜酸性粒细胞颗粒含量的分析免疫学类型(例如免疫测定)的方法和材料。 像马蹄形嗜酸粒细胞颗粒结构的存在一样,嗜酸性粒细胞颗粒内部和粘液内存在组织损伤量的嗜酸性粒细胞颗粒含量表示患者具有嗜酸性粒细胞脱颗粒状态。 此外,本发明提供可用于确定患者是否具有嗜酸性粒细胞脱颗粒状况的诊断试剂盒。
