中文摘要：

70只35日龄SPF鸡随机分成对照组和攻毒组.攻毒组经腹腔接种鸡新城疫病毒后,分别取腺胃,并用免疫组织化学方法检测组织中NDV、P物质和VIP的分布及动态变化.结果表明：P物质和VIP在两组鸡的腺胃中都有存在,且三种物质的表达量呈现正相关性,其含量在感染后有增加,证明了P物质和VIP在感染NDV后有调节动物防御系统的作用.

The results indicated that the expression of NDV,SP and VIP in stomachus glandulars increased after the chickens infected with NDV.
