Hepatic toxicity induced by dietary treatment of rats with hexaconazole: insights from a cytotoxic and genotoxic study

Abstract

ABSTRACT Hexaconazole (HEX), a widely used triazole fungicide in agriculture, was investigated for its hepatotoxic effects on albino Wistar rats. Compared to the control rats, the treated rats showed a significant increase in absolute and relative liver weight over both 3 months (p < 0.05) and 6 months (p < 0.001). Oxidative biomarkers indicated a notable rise in malondialdehyde (MDA) by 137% (p < 0.001), increased reduced glutathione (GSH) by 32% (p < 0.01), and significant reductions in antioxidant enzymes, including a 63% decrease in catalase (CAT, p < 0.001) and a 15% decrease in superoxide dismutase (SOD, p < 0.01). Glutathione-S-transferase (GST) levels also decreased significantly after 3 and 6 months (p < 0.05). The micronucleus test in liver cells indicated an elevation in the appearance of micronuclei in rats treated with HEX for 6 months (p < 0.01). This study demonstrates, for the first time, that HEX can induce genotoxicity in the liver.
