摘　　要：用ＡＢＣ免疫组织化学方法对犏牛胃肠胰（ＧＥＰ）系统中胆囊收缩素（ＣＣＫ）免疫活性细胞进行观察：犏牛从贲门至回肠部位和结肠处中有密度不等的阳性细胞。在皱胃的腺体均有分布，最密处是幽门，最疏处为胃底。在胰中也有少量形态不规则的阳性细胞。胃肠中阳性细胞形状多样，大多数可见到一个以上胞突，且细胞基部有浓密的ＣＣＫ颗粒。顶部胞突伸向腺腔，底部胞突伸向基膜和相邻细胞。并讨论了ＣＣＫ免疫活性细胞在犏牛ＧＥＰ系统中的分布规律。The Cholecystokinin(CCK) immunoreactive cells in the gastro-enteropancreatic(GEP) System of Xinjiang pien niu[yak(♀) ×cattle(♂)hybrid] were studed using an immunohistochemical staining technique avidin-biotin-peroxidase complex (ABC) method. Positive cells were observed from cardia to the ileum and colon in different densities. In abomasum, the positive cells distributed among the glandular cells with the highest density in the pyloric region and the lowest density in the fundic part. A few positive cells with irregular shapes were found in the pancreas CCK-immunoreactive cells were variform and most of them showed more than one cytoplasmic processes. The basal part of these cells were fitted with dense hormone granules. The apical cytoplasmic processes of the cells extended to the glandular cavity and the basal processes extended to the adjacent cells. The distribution of CCK-immunoreactive cells in the GEP system of Xinjiang pien niu is compared with the distribution in the cattle and other animals.
