| Research Abstract |
A cardioprotective effect was present when hypothermia at 34 ℃ was induced during ischemia, and this effect still occurred when induction of hypothermia was early after reperfusion. Futhermore, the cardioprotective effect of hypothermia, was not observed when 10 min of 15 mmHg low-reperfusion immediately after ischemia was added to reperfusion period, but did occur when 10 min of 40 mmHg low-reperfusion immediately after ischemia was added. The phosphoinositide 3'kinase(PI3K)/nitric oxide (NO) pathway, and extracellular signal-regulated kinase(ERK) pathway were involved in the mechanism underlying the effect of hypothermia.
