This study was performed to evaluate the cardioprotective effects of osthole
(OST) in a rat model of myocardial ischemia/reperfusion injury (MI/RI) and the
underlying mechanism. We exposed rat hearts to left anterior descending coronary
artery ligation for 30 min followed by 24 h of reperfusion. The results showed
that pretreatment with OST ameliorated MI/RI as evidenced by histopathological
examination. Moreover, the terminal deoxynucleotidyl transferase dUTP nick
end-labeling assay demonstrated that OST suppressed myocardial apoptosis, which
may be related to an increase in the Bcl-2/Bax ratio and inhibition of caspase-3
and caspase-9 activation. Furthermore, we determined that OST ameliorated
impaired mitochondrial morphology and the oxidation system; OST also attenuated
levels of pro-inflammatory cytokines, including tumor necrosis factor ? and
interleukins 6 and 1?. In conclusion, OST exerted a strong favorable
cardioprotective effect on MI/RI, possibly by suppressing the in?ammatory
response and inhibiting cell apoptosis.
