摘要: 该实验利用免疫组化技术,在已有实验的基础上进一步观察比较了左眼视剥夺及单眼学习后,Jun样蛋白在雏鸡两侧半球HV和LPO中表达的差异。实验结果表明:1.视剥夺2、24、48、72小时后观测到Jun样蛋白在左、右半球HV和LPO中的表达逐渐增高,并且于视剥夺48小时表达到达峰值。同时仅在视剥夺2小时后观测到两半球LPO中Jun样蛋白的表达存在差异,在其余各视剥夺时程中两侧半球的LPO、HV中Jun样蛋白的表达均无显著差异。2.视剥夺2小时和24小时后均在学习后70分钟组中观测到Jun样蛋白在左、右半球的HV和LPO中表达的显著升高,而在视剥夺2小时学习后10分钟只观测到左半球HV和LPO中Jun样蛋白表达的显著升高,在视剥夺24小时学习后10分钟中仅观测到左半球LPO中Jun样蛋白的显著升高。同时也仅在视剥夺2小时学习后10分钟观测到两侧半球HV、LPO中Jun样蛋白表达的显著性差异。3.无论单纯视剥夺组还是单眼学习组,各组同侧半球中LPOJun样蛋白的表达显著高于HV的Jun样蛋白的表达现象在视剥夺48小时后消失。

Abstract: Immunohistochemical technique was used in the present study to detect and compare Jun expressed in HV and LPO of the chick ' s two hemispheres following monovisual deprivation and one-trial passive avoidance task. It was shown that monovisual deprived 2 hours, 24 hours, 48 hours or 72 hours induced Jun expression definitely increased in HV and LPO of the two hemispheres, and Jun expression came to the highest level when visually deprived 48 hours; the expression in the left LPO was higher than that in the right LPO after being visually deprived 2 hours; monovisually deprived 2 hours and 24 hours following one-trail passive avoidance task and memory retention test at 70 minute after learning induced Jun expression to continue increase in HV and LPO of the two hemispheres; monovisually deprived 2 hours test at 10 minute just induced Jun expression obvious increase in the left LPO and HV; only the left LPO showed high level Jun expression after monovisually deprived 24 hours and test at 10 minutes; in the same hemisphere, the fact that the Jun expression of LPO was higher than that in HV disappeared after being visually deprived 48 hours.
