Phytoremedial Effect Of Ocimum sanctum Against Arsenic Induced Toxicity In Charles Foster Rats

Globally, 300 million people worldwide are exposed to groundwater arsenic poisoning in the recent time, while an estimated 10 million population are exposed to arsenic poisoning in Bihar (India). The arsenic contamination in ground water has caused serious health hazards in the exposed population. The typical symptoms of arsenicosis are observed in the exposed population mostly skin manifestations such as hyperkeratosis, melanosis, loss of appetite, neuro-behavioral disorders etc. Hence, the present study aims to develop novel drug discovery against arsenic induced toxicity in rat models. In the present study treatment groups received sodium arsenite orally at the dose of 8 mg/kg body weight daily for 90 days followed by administration of Ocimum sanctum (Tulsi) seed extract at the dose of 500 mg/ kg body weight daily by gavage method for 60 days. Their biochemical levels like liver and kidney function tests were assayed and were found with elevated levels. Furthermore, their free radical assessment such as lipid peroxidation levels were assayed which was also found to be many folds higher. Furthermore, the arsenic concentration in the tissue of liver and kidney was significantly very high. But, after the administration of ethanolic seed extract of Ocimum sanctum, there was significant restoration in the biochemical and lipid peroxidation levels. Moreover, there was also reduction in the arsenic content in the liver and kidney tissues of rats. The phytoremedial effect of this novel plant (Ocimum sanctum) denotes that it possesses antidote effect against arsenic induced toxicity.
