The physiological functions of the testis and spleen can be affected through several cellular and molecular mechanisms such as the generation of reactive oxygen species (ROS) that causes oxidative stress. This study aimed at investigating the protective effect of catechin, quercetin, and taxifolin in rotenone-induced testicular and splenetic toxicity.
Male Wistar rats were administered with 1.5 mg/kg rotenone (s.c.) for 10 days followed by post-treatment with catechin (5, 10, or 20 mg/kg), quercetin (5, 10, or 20 mg/kg), and taxifolin (0.25, 0.5, or 1.0 mg/kg) for 3 days (s.c.), followed by estimation of biochemical markers of oxidative stress, inflammatory activities, and tissue damage in testes and spleen.
Exposure of rats to rotenone caused reduced body weight gain, increased organ weight, decreased glutathione level and activities of glutathione transferase and superoxide dismutase, enhanced lipid peroxidation, and increased activities of prooxidant/proinflammatory enzymes and lactate dehydrogenase, which were mitigated by post-treatment with flavonoids. In general, quercetin and taxifolin showed better activity than catechin.
Catechin, quercetin, and taxifolin ameliorated rotenone-induced weight disturbances and oxidative damage in rats, indicating their potential relevance in toxicant and pesticide-induced tissue injury.
