We have investigated whether treatment with extracts of Colchicum autumnale (COL) might have protective effects against myocardial ischemia/reperfusion (I/R) injuries in mice. Colchicum autumnale extracts (CAE) were used in vivo and in vitro. In vivo, COL reduced the production of tumor necrosis factor-α and myeloperoxidase activity in a model of I/R. COL also reduced the number of cells positive for caspase-3 in the peri-infarct area. In vitro, we demonstrated that CAE ameliorated isoproterenol-induced cytotoxicity. These results suggest that COL may have beneficial effects against cardiac I/R injuries.Peptide supplementation ameliorates iron-induced oxidative stress and injury in isolated perfused rat heart. The present study was designed to examine the effects of iron-overload on mitochondrial bioenergetics, redox status, and lipid peroxidation in the heart and the protective effects of peptide supplementation against iron-induced toxicity. The isolated perfused rat heart was perfused with Krebs-Henseleit solution and supplied with substrates (lactate, glucose, or pyruvate) and various levels of iron. Peptide supplementation (Tyr-Gly-Gly-Phe-Leu-Gly-Pro-Arg; 300 nmol/L) was added to the perfusate to provide prolyl endopeptidase-inhibitory activity. With cardiac performance, oxidative phosphorylation, and lipid peroxidation unaltered, a reduction in cardiac output and dP/dt was observed at 10.5 microg Fe/mL of perfusate. The mitochondrial inner membrane potential and ATP production were reduced. The superoxide radical was increased; the antioxidant reduced glutathione
