Effect of Some Strains of Lactic Acid Bacteria Isolated From Some Fermented Dairy Products on Carbon Tetrachloride-Induced Hepatotoxicity and Nephrotoxicity of Albino Rats.

Abstract The current research was performed to evaluate the potential protective effect of Lactobacillus paracasei ssp paracasei, Pediococcus acidi-lactis and Lactoccus lactis ssp lactis, Sylimarin in the alleviation of health (hepatic and renal) complications caused by carbon tetrachloride (CCl4) in rats. Healthy sixty albino rats were divided into six groups, the first group was control (negative), the second group (control positive) was injected CCl4 (1 ml/kg, 1:1 v/v paraffin oil mixture, i.p. every third day for 8 weeks, The third group (CCl4 + silymarin group) receiving both CCl4 and daily silymarin therapy (50 mg/kg, oral), the fourth group: CCl4+ (Lactobacillus paracasei 1ml orally). The fifth group (CCl4+ Pediococcus acidilactis 1ml orally) and the six group (CCl4+ Lactococcus lactis (1ml orally) for eight weeks per day. Biochemical markers were tested for blood, liver and kidney tissue. Histopathological tests on liver and kidney tissues were performed. The findings obtained have shown that Lactobacillus paracasei ssp paracasei, Pediococcus acidilactis and Lactoccus lactis ssp lactis improved the disrupted biochemical parameters caused by CCl4 therapy. Besides, the findings of the histopathological analysis are in consistent with biochemical parameters and the protective ability of lactic acid bacteria suggesting that the best lactic acid bacteria was Pediococcus acidilactis that helped strengthen liver fibrosis caused by CCl4 therapy, while the best bacterium for improving renal damage was Lactoccus lactis.
