This study aimed to evaluate the protective effect of a polysaccharide extracted from fenugreek seeds (Trigonella foenum-graecum) (FWEP) against insecticide-thiamethoxam (TMX)-induced hepatotoxicity. Obtained data exhibited potent antioxidant and antibacterial potentialities. On other trend, in vivo, adult female rats were divided into four groups: controls; TMX (100 mg/kg of body weight); TMX + FWEP at two graded doses, respectively (100 and 200 mg/kg of body weight) for 30 d. Up to TMX treatment, our data showed a significant increase in plasma markers of hepatotoxicity including alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, and in lactate dehydrogenase (LDH) activities, which is coordinated with decline in total protein and albumin levels. Remarkably, a clear sign of genotoxicity was delivered by total disruption in hematological parameters and micronucleus (MN) test shown by severe chromatin degradation. These data were also associated with oxidative stress set up, histological and DNA injuries. However, co-administration with FWEP succeeded significantly in a dose-dependent manner in reducing and healing liver's hematological and genotoxic induced by TMX injuries.
