Low Dose of Carbendazim and Tebuconazole: Accumulation in Tissues and Effects on Hepatic Oxidative Stress in Mice

Ameliorative effects of gallic acid on tebuconazole-induced adverse effects in the cerebellum of adult albino rats: histopathological and immunohistochemical evidence

Tebuconazole (TEB) is a common triazole sterol demethylation inhibitor fungicide utilized to manage a variety of diseases in crops like cereals, fruits, and vegetables. The aim of this work was to assess the effects of TEB on the structure of the cerebellum in adult albino rats and possible protective impact of co-administration of Gallic acid (GA). Four groups of forty adult male albino rats were randomly selected, and the rats in group I received corn oil through daily gavage for 4 weeks. Group II received GA dissolved in the normal saline at a dose of 100 mg/kg through daily gavage for 4 weeks, group III administered with TEB dissolved in corn oil at its acceptable daily intake dose (0.02 mg/kg body weight) through daily gavage for 4 weeks, group IV rats received both TEB and GA. For light microscopic, ultrastructural, and immunohistochemical investigations, cerebellar specimens were prepared. TEB exposure led to neuronal damage in the form of degenerated Purkinje cells with vacuolated cytoplasm, areas of lost Purkinje cells, the basket cells appeared vacuolated with degenerated neuropil, the granule cells clumped with congested areas between them, dilated cerebellar islands, weak positive bcl2 immunoreactions in the Purkinje cells, and numerous GFAP-positive astrocytes. GA mitigated TEB-mediated histological changes in the cerebellar cortex. We concluded that TEB caused Purkinje neurons in the rat cerebellar cortex to degenerate and undergo apoptosis. GA had a neuroprotective benefit against TEB toxicity in the rat cerebellar cortex.

Alleviation of carbendazim toxicity effect by Moringa oleifera oil and Linum usitatissimum L. oil on testes of male rats: Physiological, histological and in silico study

Carbendazim (CBZ) is a widely used fungicide that is used to control the unwanted growth of fungi on fruits and vegetables. Sixty male rats were divided into six groups, each having ten. Group one served as control, animals belonging to group two were exposed to CBZ in the measure of 200 mg/kg body weight (BW). In the third and fourth groups, rats were administered 800 mg/kg BW of Moringa oleifera (moringa oil) and Linum usitatissimum L. (flaxseed oil), plus CBZ with the same dose given to group two. Groups five and six were administered with moringa and flaxseed oils respectively for six weeks. A marked decline was seen in oxidative stress markers, reduced glutathione (GSH), superoxide dismutase (SOD), catalase (CAT), and a rise in malondialdehyde (MDA) level in group two with severe histological disruptions. Moringa oil and flaxseed oil were used to alleviate these changes. In addition, a biocomputational molecular docking analysis of three proteins found in male rats was performed. In relation to CBZ (CID:10584007) the screened proteins namely testis-expressed protein (TX101_RAT), EPPI_RAT, and glutathione peroxidase 5 (GPX5_RAT) were docked, and their docking score were obtained (-5.9 kcal/mol), (-5.8 kcal/mol) and (-5.6 kcal/mol) respectively. By examining these interactions in 2D and 3D structures, a detailed understanding of the unique and specific binding affinity, hydrogen bonds, hydrophobic interactions, ionic bonds, and water bonds were obtained. Structure-based virtual screening (SBVS) molecular docking analysis showed that protein interaction with CBZ causes reproductive complications in protein expression and functions by hampering their normal function and blocking active sites.
