Fig. 2 shows that rats that received AF64A had reduced retention times at 7 days and 14 days after AF64A administration (p < 0.001 for all compared to the ACSF group). LA at the HT7 acupoint was found to be able to reverse the decreased retention time induced by AF64A (p < 0.01 and p < 0.001, respectively, compared to the AF64A-treated group). Again, no significant change in retention time was observed in rats that received ACSF plus LA at a sham acupoint.
