Research Abstract

Previous studies did not show chronic inflammation or vascular changes in aspiration pneumonia or its animal models. We established a mouse model of aspiration pneumonia, and showed chronic inflammation, blood vessel remodeling, and lymphangiogenesis in the model and in patients.
