The aim of this study was to perform a comparison between quercetin and deferoxamine (DFO) on the heart, liver, and duodenum in iron overloaded rabbits. Four groups of adult rabbits (each of seven) used in the current study were treated as follows for 28 days: control (C): were injected intraperitoneally (IP) normal saline every 72 hours + normal saline orally daily. T1, T2, and T3 groups were IP injected with iron dextran 100 mg/kg every 72 hours, T1 was left without treatment, group T2 was administrated with quercetin 350 mg/kg orally daily, and group T3 was injected with DFO 125 mg/kg intramuscularly (IM) daily. At the end of experiment, all animals were sacrificed, and tissue specimens were collected from the heart, liver, and duodenum for histopathological study. The results of T1 group showed edema, and iron deposition between the myocardial cells. The T2 group showed slight edema between the myocardium. T3 group showed edema, thickening, and congestion of blood vessels, all groups showed a positive result of the Prussian blue stain (PBS) compared to the control. The liver sections for the T1 group revealed iron overload, fibrosis, and hepatocyte necrosis. T2 and T3 groups showed mild vacuolation of hepatocytes, a decrease in iron overload, and these groups showed a positive result of the PBS compared to the control. Duodenum sections for T1 group showed hemochromatosis. while T2 group showed mild iron deposition. Positive result of PBS in T1 and T3 compared to the T2 and control were observed. Conclusion: Quercetin mitigates histological changes in iron overloaded rabbits due to its properties as an iron chelating agent compared to DFO. |
