Abstract
Ischemia “stroke" may occur in various combinations of clinical illnesses. The effects of such an Ischemic represent a serious problem. Oxidative stress has been shown to act as one of the main causes of Myocardial Ischemia- Reperfusion Injury (IR). Reperfusion injury is defined as the action of returning the flow of blood to an organ or tissue after a period of stroke or myocardial infarction (MI). R. Officinalis (Rosemary) has a diverse therapeutic against many illnesses. Further, recent evidence also gives R. Officinalis a major role in protecting diverse organs from harmful oxidative stress. So, R.Officinalis seems like a good protect to the myocardial against the IR Injury. The study included the components of essential oils of the rosemary leaves in the watery extract and determine whether rosemary protects form Ischemia-Reperfusion induced myocardial ischemia. We divided forty-five Wister rats into three groups Group 1 as the control group, Group 2 underwent surgery without extract therapy, and Group 3 with extract therapy. Wister rats in Group 2, and Group 3 underwent myocardial ischemia for 45 min followed by 90 min period of Reperfusion. Animals in group 3 received rosemary (1 mL/g) for 14 days also, before Ischemia, and before Reperfusion. We found that the extract comprises from many essential oils. The levels of cardiac markers (AST, ALT, and LDH) and Oxidative stress markers (NO, and LPO) in group 3 a significantly decreased compared to group 2. Based on the results, the R.Officinalis treatment lessens the effect of Ischemia-Reperfusion on the rat's heart, including the induce myocardial infarction.
