inflammation 의 종류

Inflammation (Latin, inflamatio, to set on fire) is the complex biological response of vascular tissues to harmful stimuli, such as pathogens, damaged cells, or irritants. It is a protective attempt by the organism to remove the injurious stimuli as well as initiate the healing process for the tissue. Inflammation is not a synonym for infection. Even in cases where inflammation is caused by infection, the two are not synonymous: infection is caused by an exogenous pathogen, while inflammation is the response of the organism to the pathogen.

In the absence of inflammation, wounds and infections would never heal and progressive destruction of the tissue would compromise the survival of the organism. However, inflammation which runs unchecked can also lead to a host of diseases, such as hay fever, atherosclerosis, and rheumatoid arthritis. It is for this reason that inflammation is normally tightly regulated by the body.

Inflammation can be classified as either acute or chronic. Acute inflammation is the initial response of the body to harmful stimuli and is achieved by the increased movement of plasma and leukocytes from the blood into the injured tissues. A cascade of biochemical events propagates and matures the inflammatory response, involving the local vascular system, the immune system, and various cells within the injured tissue. Prolonged inflammation, known as chronic inflammation, leads to a progressive shift in the type of cells which are present at the site of inflammation and is characterised by simultaneous destruction and healing of the tissue from the inflammatory process

 

inflammation /in·flam·ma·tion/ (in″flah-ma´shun) a protective tissue response to injury or destruction of tissues, which serves to destroy, dilute, or wall off both the injurious agent and the injured tissues. The classical signs of acute inflammation are pain (dolor), heat (calor), redness (rubor), swelling (tumor), and loss of function (functio laesa).inflam´matory

---

acute inflammation  inflammation, usually of sudden onset, marked by the classical signs (see inflammation ), in which vascular and exudative processes predominate.

catarrhal inflammation  a form affecting mainly a mucous surface, marked by a copious discharge of mucus and epithelial debris.

chronic inflammation  prolonged and persistent inflammation marked chiefly by new connective tissue formation; it may be a continuation of an acute form or a prolonged low-grade form.

exudative inflammation  one in which the prominent feature is an exudate.

fibrinous inflammation  one marked by an exudate of coagulated fibrin.

granulomatous inflammation  a form, usually chronic, marked by granuloma formation.

hyperplastic inflammation  one leading to the formation of new connective tissue fibers.

interstitial inflammation  one affecting chiefly the stroma of an organ.

parenchymatous inflammation  one affecting chiefly the essential tissue elements of an organ.

plastic inflammation , productive inflammation, proliferous inflammation hyperplastic i.

pseudomembranous inflammation  an acute inflammatory response to a powerful necrotizing toxin, e.g., diphtheria toxin, with formation, on a mucosal surface, of a false membrane composed of precipitated fibrin, necrotic epithelium, and inflammatory white cells.

purulent inflammation  suppurative i.

serous inflammation  one producing a serous exudate.

subacute inflammation  a condition intermediate between chronic and acute inflammation, exhibiting some of the characteristics of each.

suppurative inflammation  one marked by pus formation.

ulcerative inflammation  that in which necrosis on or near the surface leads to loss of tissue and creation of a local defect (ulcer).
