homeostasis/metabolism
• in moribund mice are fed ethanol unlike similarly treated wild-type mice
• ethanol fed mice exhibit an increase in IL6 serum levels unlike similarly treated wild-type mice
• ethanol fed mice exhibit an increase in TNF-alpha serum levels unlike similarly treated wild-type mice
• LPS-treated mice exhibit an increase in TNF-alpha serum levels unlike similarly treated wild-type mice
• moribund ethanol fed mice exhibit an increase in alanine transaminase levels compared with similarly treated moribund wild-type mice
• ethanol fed mice treated with LPS exhibit a greater increase in alanine transaminase serum levels compared with similarly treated wild-type mice
• mice fed ethanol exhibit mortality, cachexia, severe macrovesicular steatosis, increased apoptosis of hepatocytes, increased serum TNF-alpha and IL6 levels, focal hepatic inflammation, increased in alanine transaminase levels, and hypoglycemic serum glucose levels compared with similarly treated wild-type mice
• however, ethanol-induces oxidative damage and liver regeneration are normal

liver/biliary system

• moribund mice fed ethanol develop severe macrovesicular steatosis that is most prominent in the perivenous and midzonal regions compared with microvascular steatosis that develops in similarly treated wild-type mice

immune system
• regardless of treatment with 1-(2-cyano-3,12-dioxooleana-1,9(11)-dien-28-oyl)imidazole (CDDO-Im), LPS-exposed mice exhibit a greater increase in retinal vascular leukocyte adhesion compared with similarly treated wild-type mice
