abstract = "The effect of cadmium (Cd), coenzyme Q10 (CoQ10) and Cd+CoQ10 on the activities of superoxide dismutases (total SOD), manganese containing superoxide dismutase (Mn SOD) and copper-zinc containing superoxide dismutase (Cu,Zn SOD), catalase (CAT), glutathione peroxidase (GSH-Px), glutathione-Stransferase (GST), glutathione reductase (GR) and concentrations of ascorbic acid (AsA) and vitamin E (Vit E) in the heart of male Wistar albino rats were studied in comparison to the controls and cadmium treated animals. Cd induces a significant increase of total SOD, Cu, Zn SOD and GSH-Px activities, as well as AsA and Vit E concentrations, but leads to a significant decrease of CAT and GR activities. CoQ10 induces a significant increase of total SOD, Mn SOD, Cu, Zn SOD and GSH-Px activities, as well as AsA and Vit E concentrations. In the same group of animals the activities of CAT, GST and GR were significantly decreased. By concomitant treatment of rats with Cd+CoQ10 the activities of total SOD, Mn SOD and GSH-Px, as well as concentrations of AsA and Vit E were markedly increased. In the same group of animals the activities of Cu, Zn SOD, CAT and GR were significantly decreased. In respect to the Cd treated rats in Cd+CoQ10 partially are reversed changes (Cu,Zn SOD) of antioxidant defense system in the heart., Ispitivan je uticaj kadmijuma (Cd), koenzima Q10 (CoQ10) i Cd+ CoQ10 na aktivnost ukupne superoksid dismutaze (Uk SOD), mangan sadržavajuće superoksid dismutaze (Mn SOD), bakar cink sadržavajuće superoksid dismutaze (Cu,Zn SOD), katalaze (CAT), glutation peroksidaze (GSH-Px), glutation-Stransferaze (GST) i glutation reduktaze (GR), kao i na koncentracije askorbinske kiseline (AsA) i vitamina E (Vit E) u srcu mužjaka Wistar albino pacova u poređenju sa kontrolnom grupom i grupom tretiranom sa kadmijumom. Cd u srcu indukuje značajno povećanje aktivnosti Uk SOD, Cu,Zn SOD i GSH-Px, kao i koncentracija AsA Vit E uz značajno smanjenje aktivnosti CAT i GR. CoQ10 izaziva značajno povećanje aktivnosti Uk SOD, Mn SOD, Cu,Zn SOD i GSH-Px, kao i koncentracija AsA i Vit E. U istoj grupi životinja aktivnosti CAT, GST i GR su značajno smanjene. Istovremeni tretman sa Cd+CoQ10 dovodi do značajnog povećanja aktivnosti Uk SOD, Mn SOD i GSH-Px, kao i koncentracija AsA i Vit E. U istoj grupi životinja aktivnosti Cu,Zn SOD, CAT i GR su značajno smanjene. U poređenju sa pacovima tretiranim sa kadmijumom kod Cd+CoQ10 grupe dobijen je delimični zaštitni efekat (Cu,Zn SOD) na antioksidacioni zaštitni sistem u srcu pacova.",
