Effects of PCGE on cognitive function in cerebral I/R rats. Learning and memory retention were measured, respectively, at day12 and day 13 after reperfusion by step-down test. In the learning test, longer step-down latency (a) or fewer error times (b) indicate better learning ability. In the memory retention test, longer step-down latency (c) or fewer error times (d) indicate stronger memory retention. Data are expressed as mean ± SE. n = 8. ^#P < 0.05 versus the sham group and ^∗P < 0.05 versus the vehicle group.
