摘要
利用免疫组化技术，观察并比较剥夺一侧视觉及单眼一次性味觉厌恶回避学习后Ｊｕｎ样蛋白在雏鸡ＨＶ和ＬＰＯ的表达，结果表明正常雏鸡ＨＶ、ＬＰＯＪｕｎ表达几乎没有，剥夺左眼和单眼视觉学习后均可使Ｊｕｎ样蛋白增高。根据阳性神经元记数结果表明：１．视剥夺２．５、４、２４小时后可使Ｊｕｎ样蛋白的表达逐渐增高，而且它们之间的差异显著；２．剥夺左眼２小时和２４小时后训练，并分别于１０分钟。
The Medial Hyperstriatum Ventrale (MHV) and Lobus Parolfactorius (LPO) have been known to be the crucial part in the memory formation process in chick, the former is more important in the stability of memory, the latter is necessary for the store of long-term memory in the chick. The Jun protein derived -from c-fos proto-oncogene has been known to form a heterodimer with Fos protein, which functions as a third messenger to induce the expression of target gene. Immunohistochemical technique was used in the present study to detect and compare Jun expressed in HV and LPO of monovisual deprived chick following one-trial passive avoidance task. It was shown that the expression of Jun was scatty in the normal chick: monovisual deprived 2.5 hours, 4 hours or 24 hours induced Jun expression definitely increased in HV and LPO; monovisual deprived hours and 24 hours following one-trail passive avoidance task and memory retention test at 10 minutes and 70 minutes after learning . induced Jun expression continue to increase in HV and LPO; Jun expression in LPO was higher than that in HV.
