Others: leucine aminopeptidase and 5í-nucleotidase
Obstructive jaundice is called cholestasis (intrahepatic or extra hepatic). Enzymes increase secondary to synthesis (not cell damage) owing to obstruction or compression of bile ducts by a parenchymal mass. GGT synthesis increases when drugs enhance the
Obstructive jaundice: AP and GGT are markedly increased , while transaminases are mildly increased .
