Breeds and related genetic defects for copper associated chronic hepatitis
What is the biochem makeup of chronic hepatitis
How can chronic hepatitis differ from reactive hepatopathy?
RH- no necresis, inflammation
normal copper tissue level?
stain for copper?
distribution?
<400 ug/g
rhodanine stain
centrilobular

high ALP but normal BR
Tx for vacuolar hepatopathy
the most common cause of incrase liver enzymes is
extra-hepatic dz
Key findings with reactive hepatopathies?
no necrosis
neutrophilic vs. mononuclear inflammation
hepatitis in the dog is to ….. in the cat
