To analyze the effects of salvianolate on myocardial infarction in a murine in vivo model of ischemia and reperfusion (I/R) injury. Myocardial I/R injury model was constructed in mice by 30 min of coronary occlusion followed by 24 h of reperfusion and pretreated with salvianolate 30 min before I/R (SAL group). The SAL group was compared with SHAM (no I/R and no salvianolate)
I/R (no salvianolate)
and ischemia preconditioning (IPC) groups. Furthermore
an ERK1/2 inhibitor PD98059 (1 mg/kg)
and a phosphatidylinositol-3-kinase (PI3-K) inhibitor
LY294002 (7.5 mg/kg)
were administered intraperitoneal injection (i.p) for 30 min prior to salvianolate
followed by I/R surgery in LY and PD groups. By using a double staining method
the ratio of the infarct size (IS) to left ventricle (LV) and of risk region (RR) to LV were compared among the groups. Correlations between IS and RR were analyzed. Western-blot was used to detect the extracellular signal-regulated kinase 1/2 (ERK1/2) and protein kinase B (AKT) phosphorylation changes. There were no significant differences between RR to LV ratio among the SHAM
I/R
IPC and SAL groups (P>0.05). The SAL and IPC groups had IS of 26.1%±1.4% and 22.3%±2.9% of RR
respectively
both of which were significantly smaller than the I/R group (38.5%±2.9% of RR
P<0.05
P<0.01
respectively). Moreover
the phosphorylation of ERK1/2 was increased in SAL group (P<0.05)
while AKT had no significant change. LY294002 further reduced IS
whereas the protective role of salvianolate could be attenuated by PD98059
which increased the IS. Additionally
the IS was not linearly related to the RR (r=0.23
0.45
0.62
0.17
and 0.52 in the SHAM
I/R
SAL
LY and PD groups
respectively). Salvianolate could reduce myocardial I/R injury in mice in vivo
which involves an ERK1/2 pathway
but not a PI3-K signaling pathway.
