Abstract:
Kunming mice was used as the object to carry out the mice Y-maze experiments. The cyclic adenosine monophosphate(cAMP) was regarded as positive control, the training numbers/days (TN/TD), correct response rate (CRR), total reaction time(TRT) and active avoidance rate (AAR) was studied to evaluate the influence of different concentrations of whey liquid on learning and memory ability of mice. Compared the positive control with the blank one, the TN was significantly reduced (P<0 .05) by the positive treatment. besides, the mice were feed with camp after a half month (p<0.05), the trt was notably dropped while the aar was significantly improved; the ccr was markedly elevated（p<0.05）after a month treated. furthermore, compared whey liquid treatment group with the blank control, tn/td was significantly decreased in mice treated by whey liquid of milk , a observably improvement was found in ccr and aar but the trt was obviously decreased by the liquid after a half month(p<0.05). whey liquid of milk have no effect on ccr（p>0.05）but have a significantly influence on the TN/TD reduction and AAR improvement（P
