Path/Pharm Flashcards
(147 cards)
histology apoptosis
eosinophilic cytoplasm and basophilic nucleus
DNA laddering
fragments in multiples of 180
indicator of apoptosis
BAX and BAK
pro apoptotic
extrinsic death receptor pathway
ligand (FasL/Fas) or TNF-alpha
defective Fas-FasL
autoimmune lymphoproliferative syndrome
histology coagulative necrosis
cell outlines with no nuclei
increase eosin
cause of fibrinoid necrosis
type III HSR
seen in vasculitis, pre-eclampsia, malignant HTN
histology fibrinoid necrosis
vessel walls and thick and pink
cause of cellular swelling
decrase ATP leads to decrease activity Na/K and Ca pumps
reperfusion
red infarct
damage from free radicals
associated conditions dystrophic calcification
TB, shistosomiasis, congenital CMV, toxo, rubella, CREST, psammoma bodies
margination and rolling
e-selectin from TNF and IL-1
p-selectin
CD34
tight binding
ICAM-1 and VCAM-1
decreased in decreased CD18
PDGF
secreted by activated platelets and macrophages
stimulates fibroblasts
FGF
angiogenesis
EGF
growth via tyrosine kinases
TGF-beta
angiogenesis and fibrosis
formation granuloma
Th1 secrete IFN gamma
macrophages secrete TNF alpha
hypercalcemia from granuloma
due to calcitriol
exudates
cloudy due to lymph obstruction, inflammation, malignancy
ESR
inflammation products coat RBCs and cause aggregation
secondary amyloidosis
in inflammatory conditions
fibrils of amyloid a
dialysis amyloidosis
beta 2
may present as carpal tunnel syndrome
familial amyloid polyneuropathies
due to transthyretin gene mutaiton
