title: Prophylactic role of a herbomineral drug "Thamira parpam" against cysteamine-induced oxidative stress in liver and duodenum of rats.
abstract: Copper is known as Gunma Kaalan in Siddha literature, which means that the drug is effective for healing ulcers. The herbomineral drug "Thamira parpam" is prepared by calcining the purified copper foils with rock salt, lime juice, bracteated birth wort juice, and Alangium root decoction according to Siddha medicine. Our study investigated the possible role of Thamira parpam (TP) in the management of cysteamine-induced duodenal ulcers. Cysteamine (400 mg kg(-1) body weight(-1), two doses at 4 h interval) orally given to rats resulted in high ulcer index, increased TBARS with concomitant depletion of antioxidants such as superoxide dismutase, glutathione, glutathione peroxidase, and inflammatory markers cathepsin D, and myeloperoxidase (p < 0.01). Herbomineral drug TP (0.5, 1, and 2 mg/kg, p.o.) challenged with cysteamine attenuated the elevation of TBARS and imbalance of antioxidants. In the increases in liver inflammatory markers, tissue histopathology changes were not severe in TP treatment. Positive control omeprazole (25 mg/kg, body weight, orally) showed considerable protection against anomaly in biochemical parameters and tissue histology. Hence, our results indicate that the attenuation of oxidative stress by the herbomineral drug in experimentally induced damage to liver and duodenum of rats could be mediated by free radical quenching property.
