Prophylactic Effect of A Probiotic Strain Lactobacillus Rhamnosus Against Aluminum Chloride-Induced Intoxication in Wistar Rats: Neurobehavioral and Hematobiochemical Studies

Purpose: Aluminum (Al) and its various forms are environmental xenobiotics that pose great threats to public health. The probiotic strain has been reported to have important protective effects against aluminum cytotoxicity. Therefore, the current study was designed to assess the disruption of neurobehavioral and hematobiochemical parameters caused by chronic exposure to AlCl3, and then explore the protective effects of the probiotic strain Lactobacillus rhamnosus against these adverse in male rats. Method: Thirty-two animals were gathered into four groups: The first group served as control. The second group received 100mg AlCl3/kg bw for 12 weeks. However, the third group was administered 10mL probiotic strain /Kg (108 CFU/ml) bw/d daily for 4 weeks. Finally, group 4 received AlCl3 for 12 weeks, then the treatment was continued with probiotic for 4 weeks. Results: AlCl3 produced a decrease in body and brain weights with respect to their control. The results obtained also showed significant depression and anxiety-like behavior in the intoxicated animals, with a disturbance of the tested hematobiochemical parameters, particularly in renal and hepatic biomarkers. Overall, probiotics prevented enduring AlCl3-induced depression-like behavior in intoxicated rats. The results of the hematobiochemical, renal and hepatic analyses show a correction of the values after the administration of probiotics compared to those of intoxicated and untreated animals. Conclusion: The probiotic lactobacilli would be an alternative to reduce AlCl3 toxicity.
