|
Definition

|
|
Term
can cause dose-dependent steatosis after large IV doses; inhibition of protein synthesis, notably transporters of VLDL out of the hepatocyte |

|
|
Term
inflammation of the liver, characterized by presence of inflammatory cells |

chronic hepatitis can lead to |
|
Definition
permanent liver damage and cirrhosis |
|
|
Term
chronic liver disease in which damaged liver tissue is replaced by fibrosis, scar tissue, and regenerative nodules, leading to loss of hepatic function |
|
Definition
|
|
Term
most common example of drug-induced cirrhosis |
|
Definition
|
|
Term
can cause chronic liver diseases and cirrhosis |

Definition
methotrexate, amiodarone and methyldopa |
|
|
Term
a lysosomal storage disorder characterized by the excess accumulation of phospholipids in tissues |
