|Abstract:||<smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="place" downloadurl="http://www.5iantlavalamp.com/"> Cisplatin, a cytotoxic agent used in treating cancer, at high doses induces hepatotoxicity. In this study, we investigated the protective role of aqueous extract of aerial parts of <i>Portulaca oleracea</i> L. (Po) against cisplatin-induced hepatotoxicity in chick embryonic liver. A group of 12 day old chick embryos, acclimatized to laboratory conditions were treated with a single dose of cisplatin (100 µg), while another group received Po extract at different doses (1 and 3 mg) 6 h prior to cisplatin treatment. The biochemical parameters were estimated after 24 and 72 h of incubation. A dose-dependent increase in biochemical parameters, such as alanine transaminase, aspartate transaminase, alkaline phosphatase, lactate dehydrogenase, malondialdehyde levels and a decrease in antioxidant enzymes levels like superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, glutathione-s-transferase and reduced glutathione were observed in cisplatin-treated animals, indicating a definite damage to the liver tissue. Pre-treatment with Po extract was found to provide significant protection against cisplatin-induced hepatotoxicity, as evident by the recovered levels of the altered changes in the measured biochemical parameters. </smarttagtype>|
