Abstract

Increasing entrance of aluminum chloride (AlCl3) in many fields exposes human beings to its biotoxicity. Thereby, the present study assesses the potential ameliorative role of curcumin phytosome (CP) on AlCl3-induced hepatotoxicity. Rats were divided into four groups (n = 6): group 1 served as control; group 2 received CP (200mg CP/kg b.wt) for 21days; group 3 injected three doses of AlCl3 (30mg/kg/body weight) every 5days intraperitoneally; group 4 received CP for 7days prior to AlCl3 and then received CP concurrently with AlCl3 for another 14days. AlCl3 markedly increased (P< 0.05) the concentrations of AST, ALT, ALP, LDH, total bilirubin, and LPO as well as depleted (P< 0.05) albumin, GSH, SOD, and GPx stores in comparison to the control group. These biochemical alterations supported by the lesion observed in histological sections, increasing the expression of caspase-3 and decreasing the expression of Bcl-2. Treatment with CP modulates the hepatic dysfunction, boosting the endogenous antioxidant status, downregulating the expression of caspase-3, and upregulating the expression of Bcl-2. This hepatic ameliorative effect may be mediated by the ability of CP to repair the oxidant/antioxidant equilibrium rather than its ability to suppress apoptosis.
