Study Title:

Protective manifestation of bacoside A and bromelain in terms of cholinesterases, gamma-amino butyric acid, serotonin level and stress proteins in the brain of dichlorvos-intoxicated mice.

Study Abstract

The objective of the study was to evaluate the neuroprotective effects of bacoside A and bromelain against dichlorvos-incited toxicity. Healthy 6-8-week old, male Swiss mice were administered subacute doses of dichlorvos (40 mg/kg bw), bacoside A (5 mg/kg bw) and bromelain (70 mg/kg bw). AChE, BChE, GABA, serotonin and total protein content and their expressions were used for determination of toxic action of dichlorvos. Protective effects of bacoside A and bromelain were evaluated on the same parameters. Exposure to dichlorvos leads to significant decline in activities of AChE (p < 0.01, p < 0.001), BChE (p < 0.05) and GABA (p < 0.01) and total protein levels (p < 0.01). Antioxidant treatment significantly increased the activities of AChE (p < 0.01, p < 0.001), BChE (p < 0.05), GABA (p < 0.01) and total protein level (p < 0.05) compared to those in dichlorvos-treated mice. Overexpression of Hsp 70 protein and underexpression of phosphorylase a and b, catalase SOD and GPx were observed after dichlorvos exposure which suggests the oxidative stress. The results indicate that dichlorvos-induced neuronal damage which results in the generation of molecular expression of proteins is in agreement with the biochemical data ameliorated by bacoside A and bromelain.
