Effect of DLPhtCho and/or POPhtCho on spatial learning and memory for normal rats. Rats were orally administered with PEG, DLPhtCho (DLPC), POPhtCho (POPC), or DLPhtCho plus POPhtCho (DL & PO) everyday throughout experiments from 7 days prior to the beginning of water maze test. (A) Each point represents the mean (± SEM) acquisition latency from consecutive 2 days (n = 6). (B) Each column represents the mean (± SEM) retention latency (n = 6). + PEG, oral administration with PEG; + DLPC (5), oral administration with DLPhtCho (5 mg/kg); + DLPC (10), oral administration with DLPhtCho (10 mg/kg); + POPC (5), oral administration with POPhtCho (5 mg/kg); + POPC (10), oral administration with POPhtCho (10 mg/kg); + DL (5) & PO (5), oral administration with DLPhtCho (5 mg/kg) plus POPhtCho (5 mg/kg).
