Abstract

Ionizing radiation, besides causing direct damage also generates reactive oxygen species that are capable of inducing damage to various organs. Pretreatment with Centella asiatica 1 h prior to irradiation at a dose rate of 100 mg/kg body weight was found to be effective against radiation induced damage in the liver. The number of normal hepatocytes was higher in the Centella asiatica pretreated group in comparison with the irradiated only group. The number of binucleated cells and abnormal hepatocytes was less in comparison with the animals irradiated without Centella asiatica pretreatment. Copyright © 2005 John Wiley & Sons, Ltd.
