<i>l</i>-THP decreased the activity of creatine kinase and myeloperoxidase.

<p>(<b>a</b>) Plasma CK activity of myocardial I/R rats treated with vehicle and <i>l</i>-THP. Plasma CK activity was significantly decreased in rats that treat with <i>l</i>-THP, ^###P<0.001 vs. sham group, ***P<0.001 vs. vehicle group, n = 6. (<b>b</b>) Cardiac MPO activity of myocardial I/R rats treated with vehicle and <i>l</i>-THP (M). (<b>c</b>) Plasma MPO activity of myocardial I/R rats treated with vehicle and <i>l</i>-THP (M). Compared with the vehicle group, both cardiac and plasma MPO activity was significantly decreased, ^##P<0.01, ^###P<0.001 vs. sham group, **P<0.01, ***P<0.001 vs. vehicle group, n = 6.
