Abstract
<p><strong>Objective: </strong>To determine the effect of <em>Tridham</em> (TD) and 1,2,3,4,6-penta-O-galloyl-β-d-glucose(PGG) on lipid peroxidation levels and mitochondrial antioxidants status in experimental mammary carcinoma.</p><p><strong>Methods</strong>:<strong> </strong><em>Elaecoarpus ganitrus </em>(fruits), <em>Terminalia chebula </em>(seed coats), <em>Prosopis cineraria </em>(leaves)<em>, </em>adult female albino rats of Sprague-Dawley strain weighing 170–190 g and 7,12-dimethylbenzeneanthracene (DMBA) were used for this study. Group I control rats, Group II rats mammary carcinoma induced with DMBA (25 mg in 1 ml olive oil) by gastric intubation. Group III, IV and V DMBA induced rats were treated with TD (400 mg/kg. b. wt/day), PGG (30 mg/kg. b. wt/day) and standard drug, Cyclophosphamide (30 mg/kg. b. wt/day), respectively for 48 d by gastric intubation. Group VI and VII rats served as TD and PGG treated controls, respectively for 48 d by gastric intubation. At the end of the experimental period, the rats were anaesthetized and sacrificed. Mammary glands were isolated and used for biochemical assays and histopathological evaluation.</p><p><strong>Results: </strong>In rats with cancer, the lipid peroxide levels (LPO) were significantly increased and mitochondrial antioxidant levels were decreased. Treatment with TD and PGG decreased LPO levels and increased mitochondrial antioxidant status in mammary carcinoma bearing rats. Histopathological analysis also confirmed the therapeutic effect of TD and PGG. No significant adverse effect was observed in sole drug treated group of rats.</p><p><strong>Conclusion: </strong>TD and PGG have definite therapeutic effect in experimental mammary carcinoma and inhibit growth of cancer cells by restoring mitochondrial antioxidant status and energy metabolism to normal states.</p>
