Abstract:
AIM: To study the effect of proliferating cell nuclear antigen (PCNA) expression on alveolar macrophages (AM) and Fas/FasL expression on alveolar type Ⅱ epithelial cells induced by lipopolysaccharide (LPS) in smoking rats. METHODS: Immunohistochemistry SABC and immunofluorescence techniques were used to examine PCNA expression on AM and Fas/FasL system expression on alveolar type Ⅱ epithelial cells in smoking rats of different stages induced by LPS. RESULTS: The AM PCNA expression in smoking rats reached the highest level after 3 or 4 months. The AM PCNA expression in every groups stimulated by LPS significantly increased ( P
