Path Flashcards
MODs
SHAUN
rigor livor
purple skin
rigor algor
low temp
OSC
other sig. conditions
didnt directly cause, but contributed to death
hyperplasia
more # cells
hypertrophy
bigger cells
metaplasia
stem cells start differentiating into different type of cell
steatosis
fatty accumulation
liver
push organelles out of way
atherosclerosis
cholesterol buildup
intracell: foamy
extracell: shards
amyloidosis
small non-branching protein buildup
Congo red stain –> apple green
glassy, pink, hyaline change
hyaline change
glassy, pink, uniform
often used to describe amyloid
anthracosis
pigment:carbon buildup - eaten by m phages in lung
lipofuscin
pigment: wear and tear pig, dusty, light brown, seen more in elderly
melanin
dark brown/black and granular
hemodiserin
pigment: blood breakdown product
flaky, yellow-brown
bilirubin
pigment: Hb breakdown
yellow
Intrinsic/mitochondiral initiation of apoptosis
BCL2 -> cyto C release –> execution
extrinsic initiation of apoptosis
FAS-L on T cell binds FAS receptor –> caspase cascade –> execution
execution phase of apoptosis
caspase cascade –> activation of breakdown enzymes -> cell broken into apoptotic bodies, tagged with ligand to signal mphages –> mphages eat
causes of cell injury/death
hypox/ischemia physical agents chemical agents infx immune rxns genetic nutrition
Tx for BPH
5a-reductase inhibitor (dec amt of DHT)
metaplasia after intubation
loss of cilia, strat squ epithelium
hyperplasia in BPH
more cells, more smooth muscle and glands
Atrophy after prolonged steroid use
ZF and ZR atrophy away
