Bromuconazole caused genotoxicity, hepatic and renal failure via oxidative stress process in Wistar rats

Résumé

Abstract Bromuconazole is a triazole pesticide used to protect vegetables and fruits against diverse fungi pathologies. However, its utilization may be accompanied by diverse tissues injuries. For this, we tried to examine bromuconazole effects in liver and kidney tissues by the evaluation of biochemical and histopathological modifications also by genotoxic and oxidative stress analysis. Adult male Wistar rats were divided into four groups, each consisting of 6 animals. The control group received daily a corn oil (vehicle) orally. Three oral Bromuconazole doses were tested (1, 5 and 10 % of LD50) daily for 28 days. Bromuconazole increased the plasma activities of transaminases (AST, ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), creatinine and uric acid levels. histopathological check showed that Bromuconazole caused organs failure. This study make known that Bromuconazole caused conspicuous DNA damage either in hepatic and kidney tissues, with a significant increase in malondialdehyde and protein carbonyl levels followed by the increase in the enzymatic activity of catalase and superoxide dismutase in a dose dependent manner. Glutathione-S-transferase (GST) and peroxidase (GPx) activities were also recorded. Our results highlight that bromuconazole exposure induced genotoxic damage and organs failure that may be caused by the disturbances of oxidative stress statue in liver and kidney tissues.
