Increasing entrance of aluminum chloride (AlCl) in many fields exposes human beings to its biotoxicity. Thereby, the present study assesses the potential ameliorative role of curcumin phytosome (CP) on AlCl-induced hepatotoxicity. Rats were divided into four groups (n = 6): group 1 served as control; group 2 received CP (200 mg CP/kg b.wt) for 21 days; group 3 injected three doses of AlCl (30 mg/kg/body weight) every 5 days intraperitoneally; group 4 received CP for 7 days prior to AlCl and then received CP concurrently with AlCl for another 14 days. AlCl 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.
氯化铝(AlCl)在许多领域的应用增加使人类接触到其生物毒性。因此,本研究评估了姜黄素质体(CP)对 AlCl 诱导的肝毒性的潜在改善作用。大鼠分为四组(n=6):第 1 组为对照组;第 2 组给予 CP(200mg CP/kg 体重)21 天;第 3 组腹腔内注射三剂 AlCl(30mg/kg 体重),每 5 天一次;第 4 组先给予 CP 7 天,然后与 AlCl 同时给予 CP 14 天。与对照组相比,AlCl 显著增加了(P<0.05)AST、ALT、ALP、LDH、总胆红素和 LPO 的浓度,同时耗尽了(P<0.05)白蛋白、GSH、SOD 和 GPx 储存。这些生化变化伴随着组织学切片中观察到的病变得到证实,增加了 caspase-3 的表达,降低了 Bcl-2 的表达。CP 的治疗调节了肝功能障碍,增强了内源性抗氧化状态,下调了 caspase-3 的表达,上调了 Bcl-2 的表达。这种肝改善作用可能是 CP 修复氧化/抗氧化平衡的能力而不是其抑制细胞凋亡的能力介导的。
