Abstract

Liver toxicity is affected by several factors, including certain medications, fumes emission from factories, materials used in industries, and exposure to chemicals such as carbon tetrachloride (CCl4). Some preselected probiotic bacteria strains have been widely employed in different medical researches due to their antioxidant, anticancer, antimicrobial, anti-inflammatory characters, and hepatoprotective factor. The present study was aimed to evaluate the protective role of probiotic bacteria (Lactobacillus plantarum DSMZ 20174) and their ameliorative effects against CCl4-induced hepatotoxicity in mice. The cell cycle of hepatocytes and the expression of transforming growth factor-β (TGF-β) were assessed by flow cytometry as indicators for apoptosis. The antioxidant activity of probiotic bacteria was estimated by measuring lipid peroxidation (LPO) and scavenging 2,2-diphenyl-1-picryl-hydrazyl (DPPH). The results showed that the treatment of CCl4-administered mice by supernatant from Lactobacillus plantarum DSMZ 20174 induced an amelioration in CCl4-induced increases in serum activity of the liver enzymes and decreases in LPO and DPPH. After treatment with probiotics, the liver histopathological studies showed abundant infiltration and accumulation of mononuclear cells and fibroblast, indicating a positive effect ameliorating the damage previously induced by CCl4. In sum, the results of the present work indicate the protective effects of Lactobacillus plantarum against hepatotoxicity through antioxidant effects.
