The protective cardiac effects of Β-myrcene after global cerebral ıschemia/reperfusion in C57BL/J6 mouse.

OBJECTIVE

To investigate the protective effect of β-myrcene (MYR) on oxidative and histological damage in mice heart tissue caused global cerebral ischemia/reperfusion (IR) in C57BL/J6 mice.

METHODS

Animals(n=40) were randomly divided into four groups: (1)control, (2)IR, (3)MYR and (4)MYR+IR. The control group was received 0.1% carboxymethyl cellulose as a vehicle following a medial incision without carotid occlusion. In the IR group, the bilateral carotid arteries were clipped for 15min, and treated with the vehicle intraperitoneally(ip) for 10 days. MYR (200mg/kg) was received dissolved in 0.1%CMC for 10 days. In the MYR+IR group, the IR model was applied exactly as in the IR group, and then they were treated with MYR 10 days.

RESULTS

The cerebral IR caused oxidative damage (increase TBARS, decrease antioxidant parameters). Treatment of MYR was increased in GSH,GPx,CAT,SOD activity while TBARS level was decreased. In addition, degenerative changes in I/R group heart tissue were ameliorated by MYR administration.

UNASSIGNED

The administration of β-myrcene protects oxidative and histological damage in the heart tissue after global ischemia-reperfusion and may be useful safe alternative treatment for cardiac tissue after ischemic stroke.
