Healthy(Analysis of inflammatory diseases expected to regulate inflammation)
Conditions
Interventions
Nasal swabs and laryngeal crimpers are used for nasopharyngeal abrasion: a nasal swab coated with 0.5-1% zinc chloride solution is inserted through either nostril to reach the nasopharynx, and then ab
