| Research Abstract |
In the present study, we examined the effects of remote ischemic preconditioning (RIPC) on myocardial interstitial norepinephrine (NE) and epinephrine (Epi) levels in the rabbit left ventricle in vivo using microdialysis. As a result, the increase in dialysate NE levels until 30 min of coronary occlusion were significantly enhanced by RIPC. In addition, the suppression of dialysate NE levels during coronary artery occlusion by RIPC do not act so much cardiac sympathetic nerve function changing as other mechanism. Further study is required to elucidate the interplay between neural and humoral pathways underlyingcardioprotection by RIPC.
