Antidote effect of Bacopa moneri against arsenic induced toxicity in rats.

Arsenic catastrophe has caused serious health hazards to the exposed population. An estimated 10 million people are exposed to arsenic poisoning through groundwater. The arsenic contamination through ground water has caused health diseases such as skin manifestations, loss of appetite, nausea, bowel disorders, neurological disorders etc. Therefore, there is need for search for proper therapeutic drug against arsenic induced toxicity in rats. In the present study, arsenic induced toxic model was developed by treating Charles Foster rats (n=18) with sodium arsenite orally at the dose of 8 mg/kg body weight daily for 60 days followed by administration of Bacopa moneri (Brahmi) leaf extract at the dose of 30mg/kg body weight daily by gavage method for 60 days. After the completion of the experiment, all the animals were sacrificed and their blood samples were collected along with their vital tissues. Following parameters were assayed such as haematological assay, biochemical assay and histopathological evaluation in the present study. The haematological study comprised of RBC counts, WBC counts, platelets counts and heamoglobin percentage. For biochemical evaluation, the liver function test and the kidney function test parameters along with free radical assay were carried out. The histopathological study also showed very high degree of degeneration in the hepatocytes and the nephrocytes in the vital organ's liver and kidney. But, after the administration of ethanolic leaf extract of Bacopa moneri, there was marked restoration in the studied parameters. The haematological parameters, the biochemical parameters as well as the histopathological study showed very significant outcomes. Therefore, the present studied medicinal plant Bacopa moneri possesses antidote effect against arsenic induced toxicity in Charles Foster rats which can be used as therapeutic drug in the future after clinical approval.
