    Abstract:
    The current examination was intended to observe the defensive impacts of embelin against paraquat-incited lung damage in relationship with its antioxidant and anti-inflammatory action. Oxidative stress marker, like malondialdehyde (MDA), antioxidative enzymes, for example, superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH Px), inflammatory cytokines, such as interleukin-1β (IL-1β), tumor necrosis factor-α, and IL-6, histological examination, and nuclear factor kappa B/mitogen-activated protein kinase (NF-κB/MAPK) gene expression were evaluated in lung tissue. Embelin treatment significantly decreased MDA and increased SOD, CAT, and GSH Px. Embelin significantly reduced levels of inflammatory cytokines in paraquat-administered and paraquat-intoxicated rats. In addition, embelin suggestively decreased relative protein expression of nuclear NF-κB p65, p-NF-κBp65, p38 MAPK, and p-p38 MAPKs in paraquat-intoxicated rats. The outcomes show the impact of embelin inhibitory action on NF-κB and MAPK and inflammatory cytokines release, and the decrease of lung tissue damage caused by paraquat.
