Abstract:
Objective To detemine the effects of ketamine on c-fos gene expression during global myocardial ischemia-reperfusionMethods Forty Wistar rats were divided into 5 groups: group C as control; group CR as ischemia-reperfusion control and group KH,KM and KL treated with ketamine 1?10 -3,1?10 -4 and 1?10 -5mol/L respectively prior to ischemia-reperfusion Total cellular RNA of myocardium was extracted RT-PCR technique was applied to determining cDNA amplification products ?-actin mRNA served as an internal control Densities of DNA bands were quantified using computer image analysis systemResults As compared with the values of group C, c-fos mRNA levels were increased in group CR,KH,KM and KL(P005)Conclusions C-fos gene may involves in molecular modulation of myocardial ischemia-reperfusion injury and myocardial protection Ketamine can effectively depress the expression of c-fos gene in myocardium, the middle and the low concentrations of ketamine are more effective than the high concentrations
