Detection of ROS generation (A) and MDA production (B) in rat striatum. (A) Compared to the control group, over-generation of ROS was detected in the METH alone-treated rats, while the pretreatment with lactulose significantly decreased the ROS generation induced by METH. Significant compared to the control group (*p < 0.05); Significant compared to the METH alone-treated group (#p < 0.05). Lact, Lactulose. (B) Overproduction of MDA was observed in the METH alone-treated rats compared to the control group. The pretreatment with lactulose significantly suppressed the production of MDA resulting from the METH treatment. Significant compared to the control group (*p < 0.05); Significant compared to the METH alone-treated group (#p < 0.05). Lact, Lactulose.
