Oral administration of Auricularia polytricha aqueous extract (AEAP, 400/600 mg/kg) significantly attenuated haloperidol-induced catalepsy in rats, which may be attributed to the modulation of oxidative stress by AEAP, such as the levels of superoxide dismutase, catalase (CAT), and glutathione (GSH) (18). Here, CAT is linked to catalepsy.
