Abstract
African mesquite AM is widely used as an anti-inflammatory agent in sub-Sahara Africa especially Nigeria. Given its strong anti-inflammatory potency, this study has evaluated the neuroprotective properties of AM in the hippocampus HIP and olfactory bulb OB of rats exposed to Cd, As, Hg, and Pb. Twenty-five albino Sprague Dawley rats were randomly divided into five groups in this experiment. Group 1, the control received only water. Group 2 received heavy metal mixture HMM (PbCl2 (20 mg/kg), CdCl2 (1.61 mg/kg), HgCl2 (0.40 mg/kg), and NaAsO3 (10 mg/kg), for 60 days. Groups 3, 4, and 5 were treated with HMM along with AM at doses of 500, 1000, and 1500 mg/kg, respectively. AM decreased the Cd, As, Hg, and Pb levels in OB and HIP, restored the activities of antioxidants, Hmox-1, reduced the activities of AChE, NRF2 and NFkB and improved histopathology.
