The effects of silybin (Sil) on myocardial infarction size and ischemia- and reperfusion-induced arrhythmias were studied in anesthetized open chest Sprague-Dawley rats. It was found that pretreatment with Sil 20, 50, and 80 mg .cntdot. kg-1 iv reduced significantly infarct size by 34.7%, 35.0%, and 50.6% respectively at 4 h after ligation. Sil prevented ischemic arrhythmia only at the dose of 80 mg .cntdot. kg-1. In reperfusion experiment, pretreatment with Sil 20 mg .cntdot. kg-1 decreased significantly reperfusion-induced arrhythmia.
