Table 1. PEM initiated at 3 days after global brain ischemia did not exacerbate hippocampal CA1 neuronal death.

	CON-Sham	CON-ISC	PEM-ISC
Day 5	258±10 (n = 8)	46±7 (n = 11)*	41±7 (n = 8)
Day 21	241±10 (n = 8)	27±7 (n = 7)*	22±4 (n = 10)

Data are presented as mean ± SEM. *CA1 neuronal counts were significantly decreased in the CON-ISC group, as compared to the CON-Sham group by 1- factor ANOVA and Tukey's test (p<0.001), but the CON-ISC and PEM-ISC groups did not differ (p>0.87).
