Ethanol extract of Ammannia baccifera was studied for its protective nature against the oxidative damage of lipids, proteins and DNA in carbon tetrachloride (CCl 4 )-induced toxicity in rats. CCl 4 administration to albino Wistar rats increased the levels of lipid peroxidation, protein carbonyls and decreased the levels of total sulfhydryls. CCl 4 also induced the elevation of DNA damage measured by the comet assay. The study revealed that the administration of the ethanol extract of A. baccifera to CCl 4 intoxicated rats could significantly (P , 0.01) decrease the levels of lipid peroxidation, protein carbonyls and increased the levels of total sulfhydryls in a dose-dependent manner. It was also found that the ethanol extract of A. baccifera prevent the CCl 4 -induced elevation of DNA damage in hepatocytes. These results suggest that treatment with the ethanol extract of A. baccifera can minimize the deleterious effects caused by CCl 4 through its strong antioxidative and free radical scavenging properties.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
