In the experiment, 24 adult andWistar albino male rats weighing roundly 200-300 g were used. Group I (Control, n=8): Isotonicsaline (i.p), Group II (HgCl2,n=8):(0.01g/kg)(oral), Group III (HgCl2 + (BA) (n:8): HgCl2(0.01g/kg)+ BA (3.25mg/kg/day i.p.) group were administered. The rats in all groups were sacrificed at theend of the 10th day and their brain tissues were taken. Biochemical parameters including theenzyme activities of SOD, CAT and GSH-Px were measured. The enzyme activity of SOD wasreduced in HgCl2 treated group in comparison to the control group (p<0.001). Activity of theenzyme was increased after BA administration (p?0.001). CAT enzyme activity decreased in HgCl2and HgCl2+BA administered groups with control (p?0.001). An increase in enzyme activity in BAgroup with HgCl2 administered group was observed. GSH-Px enzyme activity decreased in HgCl2(p?0.001) and HgCl2+BA (p?0.05) groups with control. However, an increase was found in BAadministered group with HgCl2 administered group (p?0.001). It is thought that antioxidant enzymeactivities such as SOD, CAT and GSH-Px are significantly changed and BA may have a protectiveeffect in the histopathological examination of brain tissue.eninfo:eu-repo/semantics/openAccessTıbbi Araştırmalar Deneysel,Nörolojik Bilimler,Biyokimya ve Moleküler BiyolojiArticle9212713344830610.46810/tdfd.819741
