Effect of TBHQ on the lasting ERS chronically exposed to MA. (a) GRP78 expression in rat lungs by western blot; (b) GRP78 protein expression illustrated by immunohistochemical analysis (×400). Cross sections were stained with rabbit anti-GRP78 (brown) and counterstained with hematoxylin (blue) in different groups. Values are expressed as mean ± SD (). , compared with the control group; , compared with the MA group. MA: methamphetamine; THBQ: tertiary butylhydroquinone.
