ADMA levels in the rat prefrontal cortex and dorsal hippocampus. The BDL group had higher prefrontal cortex (a) and dorsal hippocampus (b) ADMA levels than the control groups. The BDLM group had lower prefrontal cortex and dorsal hippocampus ADMA than the BDL group, indicating the effectiveness of melatonin. *P<0.05, **P<0.01 versus SHAM group; #P<0.05, ##P<0.01 versus BDL. ADMA, asymmetric dimethylarginine; BDL, bile duct ligation; BDLM, bile duct ligation treated with melatonin; SHAM, sham control; SHAMM, sham control treated with melatonin.
