ABSTRACT
Objective To explore the influence of polyamine-cholesterol cationic liposome (PCL)-mediated CpGODN aerosol on eosinophiles in the lung tissue of mouse asthma model. Methods Mouse asthma model was replicated by challenging with 1% ovalbumin aerosol. Mice were categonied into four groups, namely normal control, asthma control, CpGODN/PCL treatment group and CpGODN treatment group (6 each). The left lungs of mice were harvested, serially sectioned, hematoxylin and eosin (HE)-stained, and the infiltration of eosinophiles (EOS) was examined under microscope. Meanwhile, the bronchoalveolar lavage fluid (BALF) was collected for total and eosinophil cells count. Results An ovalbumin challenged mouse asthma model was successfully replicated. Pathological observation of the lung of asthma control showed increase in mucous secretion in alveolar space and peribronchial infiltration of large amount of inflammatory cells, primarily EOS and lymphocytes. The total cell number, EOS number and the ratio in BALF were significantly higher in asthma control group compared with that in both normal control group and CpGODN treatment group (P
