patho acute inflammation Flashcards
increased blood flow to the area causes
redness and heat
fever in patient caused by
Release of pyrogens and prostaglandins will cause a fever in the patient.
order of events that a neutrophil must follow to capture and kill a bacterium?
Chemotaxis, activation, margination, diapedesis, recognition attachment, phagocytosis
which are granulocytes?
arise from?
all the phils
neutrophils
eosinophils
basophils
arise from myeloblast
high neutrophils in FBC indicate?
bacterial infection
high lymphocytes in FBC indicate?
viral infection
Chronic inflammation - liquefactive necrosis?
necrosis with predominantly enzymatic degradation
in a cell: hyper eosinophilic debris
organ: initial swelling then hole
occurs in loose tissue. and where lots of neutrophils present
CI: caseous necrosis
necrosis with a cheese like appearance.
tissue: hyper eosinophilic with amorphous debris
organ: cottage cheese
occurs in TB and inflammation
CI: fat necrosis
necrosis associated with destruction of adipose tissue
tissue: small white lesions which are lumpy
seen in breast trauma and acute pancreatitis.
(lipase break TAGs into fa. fa react with Ca to create chalky deposits)
CI: What cells are seen in foreign body granulomas?
why do foreign body granulomas occur?
macrophages, epithelioid macrophages, and fibroblasts.
when macrophages have tried to phagocytose a foreign body but have failed
>recruit the rest of the immune system to try to attack the foreign body.
what are xanthomas?
deposits of cholesterol
What are the predominant cell types in chronic inflammation?
Macrophages and lymphocytes
