inflammation = sum of all reactions of the connective tissue prior to tissue damage. Inflammation is a vital reaction, ie bound to life.
causes
- busy organisms [fungi, worms, bacteria, viruses ,...]
-
allergens [foreign allergens, Car allergens]
-
physical and chemical stimuli [poisons, Radiation ,...]
-
foreign bodies [objects tumors ,...]
expiry of an inflammatory response
impairment (Functional laesa)
injurious action of a substance
tissue damage (Alteration)
Local reaction of the organism
Transient vasoconstriction the arterioles ("initial ischemia")
vasodilation of arterioles and formation of an active hyperemia (increased blood circulation by 10-fold)
REDNESS (rubor) / / WARMING (Calor)
enlargement of the lumen of the capillaries and venules
exudation (plasma leakage into the interstitium
)
SWELLING (tumor)
increasing the viscosity of the blood
(irritation of the nerve terminal)
PAIN (Dolor)
emigration of leukocytes from the vessels into the damaged Tissue ("chemotaxis" = attraction of leukocytes
phagocytosis of bacteria (or the like.) And tissue debris
regression with resorption of
exudate without tissue destruction
"restitution ad integrum" =
complete cure
progression in the continuance of
harmful effect / inflammatory response
proliferation
= formation of granulation tissue with capillary buds
scarring
(regression of the capillaries)
Common symptoms
-
leukocytosis with left shift
-
increase in immunoglobulins
-
fever as a sign of metabolic increase
-
subjective fatigue and malaise
influences on the course of the inflammatory Reaction
-
type of inflammation caused
-
duration of the injurious effect
-
responsiveness and disease resistance of the affected organism
forms of inflammation
first serous inflammation
second fibrinous inflammation
third purulent inflammation
