Mercuric chloride is an environmental pollutant that affects the nervous systems of mammals. Oxidative damage is one of the mechanisms of its toxicity, and antioxidants should mitigate this effect. A vegetable with antioxidant activity is Launaea taraxacifolia, whose ethanolic extract (EELT) was investigated in this experiment to determine its effect against mercuric chloride (MC) intoxication in rat brain. Thirty male Wistar rats were randomly assigned into five groups (n = 6) as follows: control; propylene glycol; EELT (400 mg/kg bwt) for 19 days; MC (HgCl) (4 mg/bwt) for 5 days from day 15 of the experiment; EELT+ MC, EELT (400 mg/kg bwt) for 14 days + MC (4 mg/bwt) for 5 days from day 15 of the experiment. All treatments were administered orally by gastric gavage. Behavioral tests were conducted on the 20th day, and rats were euthanized the sameday. Blood and brain tissue were examined with regard to microanatomical parameters. Data were analyzed using analysis of variance with statistical significance set at p<.05. MC induced significant (19%) reduction of thrombocytes, which was ameliorated by 57% (p<.05) by pretreatment with EELT when compared with the MC group. Behavioral results showed that MC elicited significant reduction in transitions, rearings, forelimb grip strength, and latency of geotaxis. Histologically, MC induced alterations in the microanatomy of cerebral cortex, dentate gyrus, cornu ammonis 3, and cerebellum of rats. Treatment with EELT prior to MC administration significantly reduced the effect of MC on the hematological, behavioral, and ameliorated histological alterations of the brain. These findings may be attributed partially to the antioxidant property of EELT, which demonstrated protective effects against MC-induced behavioral parameters and alteration of microanatomy of rats' cerebral cortex, hippocampus, and cerebellum. In conclusion, EELT may be a valuable agent for further investigation in the prevention of acute neuropathy caused by inorganic mercury intoxication.
