Serum mercury (Hg) levels, hippocampal production of reactive oxygen species as determined by 2′,7’-dichlorofluorescein (DCF) levels, and malondialdehyde (MDA) levels in rats. ^* Indicates a significant difference between the control and dimethylmercury (MeHg) groups or between the Dendropanax morbifera leaf extract (DML) and DML-MeHg groups (P < 0.05); ^# indicates a significant difference between the control and DML groups or between the MeHg and DML-MeHg groups (p < 0.05; n = 7 per group). Serum Hg, hippocampal DCF, and MDA levels are significantly increased in the MeHg group and are reduced by DML treatment. The data represent means ± standard error of the mean (SEM)
