Abstract
This study aimed to evaluate the effect of daily sublethal doses of aluminum (Al) on hematological, physiological, biochemical, and behavioral changes in male albino Wistar rats. In addition, Al tissue accumulation and histopathological changes in the cerebral cortex, liver, and kidney were examined. The rats were randomly separated into three groups. Group 1 included rats who received the median deadly dose (LD
) of aluminum chloride (AlCl
), group 2 served as the control, and group 3 was treated with a non-lethal dose of AlCl
(1.5 mg/kg) intraperitoneally for 45 days. At defined time intervals, hepatic and renal specific enzymes and biochemical activity were measured. In addition, we examined Al accumulation, the condition of the liver via histological methods, and the impact on the cerebral cortex. In comparison to the controls, rats treated with AlCl
exhibited a rise in AST, ALT, and ALP enzyme activity. We also saw a significant decrease in body weight and a decrease in total protein, lipids, cholesterol, acetylcholinesterase (AChE), RBCs, and Hb levels compared to the control group. Histopathological examination suggested severe changes in the liver, kidney, and cerebral cortex of the rats. The current study indicates that sublethal daily exposure to AlCl
causes hazardous effects, as increased Al concentration in the body is shown to induce detrimental biochemical and histological changes as well as decreased body weight. Therefore, careful attention should be given to treatments requiring long exposure in patients and the potential for accumulation via food and drinking.
