Apoptotic cell ratio among the four groups measured by the TUNEL method. Apoptotic cell ratio stands for the number of positive cells/total number of cells. Black arrows indicate positive cells a. NAVA had a significantly lower apoptotic cell ratio compared with CMV or PSV b. (Methyl green was used as a counterstain) *: P < 0.05, adjusted for the Bonferroni method
