Background: There are gender differences in the oxidation-reduction reactions. Doxorubicin (Dox) is a chemotherapeutic drug that can produce oxidative stress which may require prevention by antioxidants. Aim: The study aimed to investigate the gender-dependent changes in Dox-induced oxidative stress, and the protective effects of coenzyme Q10 (CoQ10). Materials and Methods: Rats were administered CoQ10 orally for 17 days. On day 13, some rats receiving CoQ10 received a single intraperitoneal dosage of Dox, whereas other rats received normal saline. Glutathione (GSH), malondialdehyde (MDA), and total anti-oxidant capacity (T-AOC) were measured in both genders of albino rats. Results: Dox significantly reduced both GSH and T-AOC levels and caused a significant increase in MDA. The administration of CoQ10 significantly prevented these changes. Dox caused a larger reduction in GSH in males than in females, while CoQ10 caused more protection in females. Dox caused a higher increase in MDA levels in males. Conclusion: Pre-treatments with CoQ10 may protect against Dox-induced oxidative stress, with gender-dependent variations in the extent of these Dox/CoQ10 effects.

Background: Oxidative stress plays an important role in chronic complications of diabetes, cancer, liver disorder etc. The free radicals such as superoxide anions, hydrogen peroxides are causing the oxidative stress and it involves the cellular damage. Evidences recommended that the natural medicines from plant sources are treated to overcome the oxidative stress complications. Objective: The aim of the present is to find the antioxidant activity of the ethanolic extract of Terminalia catappa leaves and Terminalia chebula fruits in the doxorubicin (DOX) induced toxicity rats. Methods: Oxidative stress is induced with a single dose of doxorubicin and then the animals were treated with a dose of various concentration of ethanolic extract of T. catappa leaves and T. chebula fruits (200, 300 mg/kg/b.w) for 21 days. After the treatment, lipid peroxide (LPO), reduced glutathione (GSH), vitamin C, vitamin E, glutathiones- transferase (GST), glutathione peroxidase (GPx), superoxide dismutase (SOD), catalase levels are determined. Propranolol 25mg/kg is used as standard drug. Results: In the present study, after the treatment of doxorubicin the levels of SOD, CAT, GSH, GST, GPX, vitamin C, vitamin E levels are decreased and LPO level is increased. After the treatment of T. catappa leaves and T. chebula fruits the levels were returned to the normal level. Conclusion: The results proved that the ethanolic extract of T. catappa leaves and T. chebula fruits may protects the cells from oxidative stress induced by the doxorubicin induced toxicity rats.
