| pubmed-article:12870700 | pubmed:abstractText | The effect of melatonin (MLT) on the isolated rat heart was studied using the standard perfusion conditions (Langendorff preparation) and model of calcium paradox (Ca(2+)-paradox). Ca(2+)-paradox was induced by 1 minute perfusion with Ca(2+)-free Krebs-Henseleit (KH) solution and subsequent 20 minutes perfusion with a normal Ca(2+)-containing KH solution. In MLT group, MLT (10 micromol/l) was in the perfusion solution throughout the experiment. In controls, there was no MLT. | lld:pubmed |
