The purpose of this study was to use the TUNEL method for datecting I/R cardiomyocyte apoptosis to investigate the effect of ischemic preconditioning(IP)
the activators of protein kinase C(PKC) and protein tyrosine kinase(PTK) on ischemia/reperfusion(I/R) cardiomyocyte apoptosis
and the relationship betWeen PKC and PTK for IPs anti-apoptosis effect in rat hearts.The results showed that:(1)IP could reduce MR cardiomyocyte apoptosis significantly (P<0.01);(2)PMA
the activator of PKC
and anisomycin
the activator of PTK
could also reduce I/R anisomycins anti-apoptosis during MR
and lavendustin A
the inhibitor of PTK
could block the effect of PMAs anti -apoptosis during I/R.These data suggest both PMA and anisomycin could mimic IPs anti-apoptosis effect during I/ R;PTK seems to be downstream of PKC for IPs anti-apoptosis effect during im injury in rat hearts.
