liver/biliary system
• hepatocellular swelling without lipidosis, characterized by abundant, lightly granular, pale, eosinophilic cytoplasm, is observed in some animals
|
• liver weight/body weight ratio is significantly increased in males and females, with no significant change in body weight observed
|
• individual hepatocyte necrosis or apoptosis, and a few scattered foci of necrosis are seen, sometimes with secondary neutrophilic infiltrates, in some livers
|
pale liver
(
J:84422
)
• liver is lighter red in color compared to normal liver
|
homeostasis/metabolism
• at 3 weeks of age, plasma total cholesterol is decreased 30% compared to controls and is decreased 80% at 2 months of age
|
• liver microsomal NADPH-cytochrome P450 activity toward cytochrome c, NKK, and acetominophen (AP), as well heme oxygenase (HO) activity are decreased in mice at 3 weeks
• at 2 months of age, mice have 5-8% of normal activity levels toward NKK and AP, and barely detectable HO activity
|
behavior/neurological
• mice are still unconscious 10 h after a single 60 mg/kg dose of pentobarbital, unlike controls which regained righting reflex after about 30 min
|
growth/size/body
• liver weight/body weight ratio is significantly increased in males and females, with no significant change in body weight observed
