LEC5 - INFLAMMATION Flashcards
The word inflammation from the Latin
inflammare
(to set on fire)
according to him, inflammation is not a disease but only a protective response
john Hunter, Scottish surgeon in 1793:
Inflammation is a protective response involving:
- host cells
- blood vessels
- proteins and
- other mediators
host cell are involved if the inflammation is ?
acute or chronic
A response of vascularized tissues to infections and damaged tissues that brings cells and molecules of host
defense from the circulation to the sites where they are needed, in order to eliminate the offending agents
inflammation
The word inflammation from the Latin

fire)
he profound the 4 signs of inflammation - cardinal signs
o Rubor – redness
o Tumor – swelling

John Hunter (1793)
she Discovered the process of phagocytosis
Elie Metchnikoff (1880s)
in order to clear up or eliminate the initial cause of inflammation is through the process of
phagocytosis
2 etiology of inflammation
exogenous and endogenous
exogenous causes of inflammation
physical agents
chemical agents
biological agents
endogenous causes of inflammation
circulation disorders
enzyme activation
metabolic products deposals
Physical agents of inflammation
o Mechanic agents:
o Thermal agents:
under the physical agents, give example of mechanical agents
fractures, foreign, sand
under the physical agents, give example of thermal agents
burns or freezing
example of chemical agents
toxic gases, acids, bases
example of biological agents
microorganism
an endogenous causes, give example of circulation disorders
thrombosis, infarction, hemorrhage
an endogenous causes, give example of enzyme activation
acute pancreatitis
an endogenous causes, give example of metabolic deposals
uric acid, urea, cholesterol
all intracellular accumulation will fall in what category of exogenous causes of inflammation??
metabolic product deposals
