本实验通过给动物喂以添加不同剂量锌的饲料（每公斤干饲料中添加２００、４００、８００、１２００ｍｇ硫酸锌，即Ｚ１、Ｚ２、Ｚ３、Ｚ４组），应用Ｙ－迷宫，步入试验及跳台试验等方法来探讨锌在学习记忆中的作用。结果表明：各组动物体重及旷场行为无显著差异；Ｚ１组在Ｙ－迷宫中达到学会标准所用的资数明显减少；Ｚ４组在步入试验中，潜伏期明显缩短，在跳台试验中，记忆保持率则有下降的趋势；实验组血锌较对照组有不同程度的提高；海马锌的含量除Ｚ４组外，其余三组均较对照组有显著升高；本实验提示；添加低剂量锌对学习记忆有促进作用，而过高剂量锌对学习记忆有损害作用。
In this experiment, animals were fed with different doses of zinc (200, 400, 800 and 1200 mg of zinc sulfate per kilogram of dry feed, ie Z1, Z2, Z3 and Z4), Y-maze, Jumping test and other methods to explore the role of zinc in learning and memory. The results showed that there was no significant difference in body weight and open-field behavior in each group. The number of Z1 group in the Y-maze significantly reduced the number of learning standards; in the Z4 group, the latency was significantly shortened in the walk-in test. Retention rate decreased; the experimental group blood zinc levels were increased to varying degrees compared with the control group; the content of zinc in the hippocampus except the Z4 group, the other three groups were significantly higher than the control group; this experiment prompted; add low-dose zinc On learning and memory has a promoting effect, and excessive doses of zinc on learning and memory damage.
