I Overview of inflammation Definition: Inflammation is the reaction of living tissues to all forms of injury a defensive response of living tissue with a complex reaction in vascularized connective tissue and cellular reaction intended to eliminate the initial cause as well as the necrotic cells and tissues

Ⅰ. Overview of inflammation Definition: Inflammation is the reaction of living tissues to all forms of injury. A defensive response of living tissue with a complex reaction in vascularized connective tissue and cellular reaction intended to eliminate the initial cause as well as the necrotic cells and tissues

inflammation Tw0 main components Vascular reaction Cellular reaction PRotective response Eliminate the initial cause Destroy harmful agents INtertwined with the process of repair Reconstitute damaged tissue

Two main components: Vascular reaction Cellular reaction Protective response: Eliminate the initial cause Destroy harmful agents Intertwined with the process of repair Reconstitute damaged tissue inflammation

Inflammation is a double blade sword Have Potential to cause harm Basically a protective reaction The basis of life threatening allergic .Desdroy dilute or isolate reaction to insect or drugs InJurious agents .Pericardial inflammation Clear inflammation resulting in dense encasing scar that impair heart .Make wound tissue function healing Chronic inflammation often cause fibrosis of diseased organs

Inflammation is a double blade sword Basically a protective reaction •Desdroy, dilute or isolate injurious agents •Clear inflammation •Make wound tissue healing Have Potential to cause harm •The basis of life￾threatening allergic reaction to insect or drugs •Pericardial inflammation resulting in dense encasing scar that impair heart function •Chronic inflammation often cause fibrosis of diseased organs

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

Alteration(变质): degeneration and necrosis (Necrostic type) Exudation(渗出): vascular changes, (inflammatory hyperemia) extravasation of leukocyte and fluid (common cold, watery exudate on mucous membrane of nose) proliferation(增生): epithelium, connective tissue, and blood vessels (glanuloma, tonsillitis ) II.
