Optimization of the cardioprotective dose of rhSLPI for ARVMs subjected to sI/R. ARVMs were cultured with various concentrations of rhSLPI and treated over three different periods, including (A and B) 2 h prior to sI, (C and D) at the onset of sI and (E and F) at the onset of reperfusion. Following rhSLPI treatment, all groups were subjected to 20 min sI followed by 2 h reperfusion. The percentage of viable cells and released LDH activity in all groups were determined. The results are presented as the mean ± standard error of the mean (n=3). *P<0.05 vs. control group; #P<0.05 vs. sI group. rhSLPI, recombinant human secretory leukocyte protease inhibitor; sI, stimulated ischemia; ARVM, adult rat ventricular myocytes; LDH, lactate dehydrogenase; sI/R, stimulated ischemia/reperfusion.
