Abstract
Endosulfan (EDS) is one of the most widely organochlorine insecticide used in many parts of the world, although it is currently banned or severely restricted in use in some countries. EDS causes a variety of negative effects in non-target species including humans. Therefore, the aim of the present study was to investigate the possible protective effects of Lactobacillus plantarum BJ0021 on toxicity, oxidative stress, and apoptosis induced by EDS intoxication on liver and kidneys of pregnant rats. This pesticide induced a significant increase in total cholesterol, alanine-amino transferase (ALAT), aspartate-amino transferase (ASAT), alkaline phosphatase (ALP), gamma-glutamyl transpeptidase (GGT), urea and creatinine in serum, while urinary urea and creatinine were lower than those of the control group. In the liver and kidney, lipid peroxidation increased significantly, the antioxidant levels, such as superoxide dismutase (SOD) and catalase (CAT) were markedly depressed and TdT-mediated dUTP-biotin Nick End Labeling (TUNEL) revealed more apoptotic cells. In contrast, co-administration of L. plantarum BJ0021 to EDS-treated animals ameliorated most of these biochemical parameters, but the activity of antioxidant enzymes (SOD, CAT) did not modify and the number of apoptotic nuclei remained significantly raised in kidney compared to control. In conclusion, the administration of L. plantarum BJ0021 decreased apoptosis and might play a protective role in reducing toxicity of EDS in pregnant rats.
