I. Basic Pathologic Changes of Inflammation Alteration(3E): degeneration and necrosis(Necrostic type) (massive necrosis of liver in fulminant hepatitis Exudation(渗出): vascular changes, (inflammatory hyperemia) extravasation of leukocyte and fluid (common cold, watery exudate on mucous membrane of nose) proliferation(#4E): epithelium, connective tissue, and blood vessels (granuloma, tonsillitis
