Abstract
INTRODUCTION
Cadmium (Cd) produces severe oxidative stress, which can result in serious clinical consequences and tissue injury. The aim of the present survey was to investigate the protective effects of native Iranian probiotics (Lactobacillus rhamnosus, L. helveticus, and L. casei) against cadmium (Cd)-induced toxicity against the small intestine and lung at histopathological and biochemical levels.
MATERIALS AND METHODS
Twenty-one adult male Wistar rats were randomized into three groups of seven rats (control, Cd-treated (3 mg/kg), and concomitant Cd and mix probiotic treatment for 30 days). Histological alterations were appraised via hematoxylin & eosin, Trichrome Masson, and PAS staining. The qRT-PCR technique was applied to assess the expression of pro-apoptotic, anti-apoptotic, and pro-inflammatory genes. Antioxidant enzymes activity was measured via ZellBio kits.
RESULTS
Probiotic-treated rats displayed low production of lipid peroxides, reduced malondialdehyde (MDA) level, and elevated contents of superoxide dismutase (SOD) and catalase (CAT) enzymes compared with Cd-treated rats. The results of qRT-PCR demonstrated the up-regulation of Bax, p53, and caspase 3 and down-regulation of Bcl2, TNF-α, and IL-6 genes in both the intestine and lungs of mix probiotic-treated rats compared with Cd-treated animals. Histopathological findings revealed that the probiotic formulation improved Cd-triggered tissue damage in the intestine and lungs.
CONCLUSION
The strong cytoprotective benefits of Iranian probiotics against Cd-induced tissue injury observed in this study may be due to their anti-inflammatory and antioxidant properties. Therefore, additional clinical and experimental research is required to explain the precise mechanisms of probiotics' beneficial impacts and underline their potential therapeutic use.
