Effect of baicalin and baicalin-bovine serum albumin nanoparticle against bendiocarb exposure in rats

Background

The aim of the study was to investigate the effect of baicalin and baicalin-bovine serum albumin nanoparticles against bendiocarb exposure in rats.

Methods

Eighty male Wistar Albino rats aged 4-6 weeks were used. Corn oil (vehicle) alone was administered to the control group. To other groups, BSA-nanoparticle equivalent to that binding baicalin at a dose of 20 mg/kg.bw, 20 mg/kg.bw baicalin, baicalin-BSA nanoparticle equivalent to that binding baicalin at a dose of 20 mg/kg.bw, 4 mg/kg.bw bendiocarb, combination of 4 mg/kg.bw bendiocarb and 20 mg/kg.bw baicalin, combination of 4 mg/kg.bw bendiocarb and BSA-nanoparticle equivalent to that binding baicalin at a dose of 20 mg/kg.bw and combination of 4 mg/kg.bw bendiocarb and baicalin-BSA nanoparticle equivalent to that binding baicalin at a dose of 20 mg/kg.bw was administered to animals by oral gavage with vehicle for 21 days, after which organs (liver, kidney, brain, testes, heart and lung) and blood samples were collected. Blood/tissue oxidative stress (MDA, NO, GSH, SOD, CAT, GSH-Px, GR, GST, G6PD), serum biochemical (glucose, triglyceride, cholesterol, BUN, creatinine, uric acid, total protein, albumin, LDH, AST, ALT, ALP and pseudocholinesterase) and liver and kidney apoptotic/anti-apoptotic (caspase 3, 9, p53, Bcl-2 and Bax) parameters were evaluated. Body weights/organ weights and plasma/liver bendiocarb analyses were obtained.

Conclusion

While bendiocarb administered alone caused oxidative stress/tissue damage, baicalin and baicalin-BSA nanoparticle showed a mitigating effect. However, this effect was more pronounced in the baicalin-BSA nanoparticle group. BSA-nanoparticle alone did not have a significant effect in reversing the adverse effect caused by bendiocarb.

Bendiocarb-induced nephrotoxicity in rats and the protective role of vitamins C and E

Bendiocarb is a pesticide carbamate which is used to protect agricultural products and animals. In this study, rats were given orally with bendiocarb and also other chemicals via gavage. Male rats were randomly divided into eight groups (n = 6): group 1 served as controls; group 2 received vitamin C (100 mg/kg bw); group 3 received vitamin E (100 mg/kg bw); group 4 received vitamins C plus E; group 5 received bendiocarb (0.8 mg/kg 1/50 LD₅₀); group 6 received both bendiocarb and vitamin C; group 7 received both bendiocarb and vitamin E; and group 8 received both bendiocarb and vitamin C and E via oral gavage. Degenerative changes and biochemical differences in rat kidney were investigated after 4 weeks of especially bendiocarb treatment. While biochemical values were normal in the control group, it was observed that CAT, SOD, GPx, and GST values decreased, while MDA, creatine, urea, and uric acid values increased in the pesticide-treated groups. It was also reported that bendiocarb caused cytopathological and histopathological changes in rat kidney. We have shown that the application of vitamins has a therapeutic effect on the evaluated parameters.
