A common heavy metal in many facets of daily life is aluminum (AlCl3), which can be found in food, toothpaste, cosmetics, food additives, and numerous pharmaceutical items. The hippocampus, liver, and kidneys have the highest concentrations of this powerful neurotoxin, which also accumulates over time and contributes to the development of a number of cognitive disorders. Long-term overconsumption of AlCl3 results in hepatic and renal toxicity as well as neuronal inflammation. The purpose of the research is to assess the potential protective effects of various L-carnitine dosages as an antioxidant against hebato, renal, and neuronal toxicity in rats caused by aluminum chloride (AlCl3) (20 mg/kg, 1/20 LD 50). Six groups (n = 6), consisting of 36 adult albino rats, were randomly assigned. Saline was administered to the control group (GI) by injection. (GII) had given an injection of L-carnitine at a low-dose of 75 mg/kg body weight. An injections of L-carnitine at a high-dose (150 mg/kg) were given to (GIII), and AlCl3 (20 mg/kg) was given to (GIV). (GV) administered with L-carnitine (75 mg/kg) and AlCl3 (20 mg/kg) by injection. For 60 days, AlCl3 (20 mg/kg) and L-carnitine (150 mg/kg) were administered to GVI by injection. Furthermore, the histological structure of the cortex, hippocampus, and hepatic renal tissues appeared to change in response to AlCl3. L-carnitine therapy lessened the negative effects of AlCl3. The observable improvement in the tissues of the brain, liver, and kidneys further supported this histopathologically. It is possible to draw the conclusion that L-carnitine holds promise as a corrective measure for AlCl3, which causes renal toxicity and neural hepatotoxicity in rats. When it comes to adult albino rats, L-carnitine has a negative impact and exhibits ameliorative effects against aluminum chloride.
铝(AlCl₃)是日常生活诸多方面常见的重金属,在食物、牙膏、化妆品、食品添加剂及众多药品中都能找到。这种强效神经毒素在海马体、肝脏和肾脏中的浓度最高,且会随着时间累积,导致多种认知障碍。长期过量摄入AlCl₃会导致肝脏和肾脏毒性以及神经元炎症。本研究的目的是评估不同剂量的L - 肉碱作为抗氧化剂对大鼠因氯化铝(AlCl₃)(20毫克/千克,1/20 LD 50)所致肝脏、肾脏和神经元毒性的潜在保护作用。随机分配了六组(n = 6),共36只成年白化大鼠。对照组(GI)通过注射给予生理盐水。(GII)以75毫克/千克体重的低剂量注射L - 肉碱。(GIII)给予高剂量(150毫克/千克)的L - 肉碱注射,(GIV)给予AlCl₃(20毫克/千克)。(GV)通过注射给予L - 肉碱(75毫克/千克)和AlCl₃(20毫克/千克)。(GVI)通过注射给予AlCl₃(20毫克/千克)和L - 肉碱(150毫克/千克),持续60天。此外,皮质、海马体以及肝肾组织的组织结构似乎因AlCl₃而发生了变化。L - 肉碱治疗减轻了AlCl₃的负面影响。大脑、肝脏和肾脏组织中可观察到的改善在组织病理学上进一步证实了这一点。可以得出结论,L - 肉碱有望作为一种纠正措施来应对在大鼠中引起肾脏毒性和神经肝毒性的AlCl₃。对于成年白化大鼠,L - 肉碱对氯化铝有负面影响并表现出改善作用。
