Instillation of Particulate Suspensions to the Lungs

Inhaled fine particulates are thought to cause chronic pulmonary inflammation through the deposition of particulates into the lungs. To investigate the effect of fine particulates on the lungs, instillation of suspension of particulates into the lungs is required. This protocol describes direct injection of suspensions of fine particulates into the airway. We also show examples of typical lung immune responses after particulate administration.
