Abstract
Cyclophosphamide (CP) is a potent chemotherapeutic agent and is also known to interact with specific biological molecules and produce numerous side effects such as genotoxicity, neurotoxicity, reproductive toxicity and nephrotoxicity. CP induces genotoxicity by generating oxygen/nitrogen derived free radicals during chemotherapy and causes DNA damage. Hence, to overcome such side effects of chemotherapeutic agents antioxidants are recommended. Gallic acid (GA) a phenolic compound is commonly exists in variety of fruits and in many plants. In the present study, genoprotecive effects of GA against CP induced genotoxicity in Swiss albino mice were evaluated by using comet assay, bone marrow, and peripheral micronucleus (MN) assays. CP produced oxidative stress induced hepatic damage was assessed by estimating the activity of liver superoxide dismutase (SOD), reduced glutathione content (GSH), and also by examining the histological alterations induced by CP in hepatic tissue of mice. It was noticed that, GA pretreatment significantly reduced the frequency of MN and DNA strand breaks induced by CP. GA also protected the hepatic tissue against CP induced reactive oxygen species (ROS) mediated damage and was evident by increased levels of liver SOD and GSH. GA ameliorated the histological changes induced by CP in hepatic tissue. These findings suggest that, GA is a versatile antioxidant with promising protection against CP induced genotoxicity and hepatic damage in Swiss albino mice.
