摘要
比较观察血管活性肠肽(VIP)在莱芜黑山羊胃肠道内的分布,用免疫组织化学方法显示胃肠壁各层及各肠段的分布情况。结果表明,血管活性肠肽以贲门部数量最多,结肠、空肠、幽门、盲肠、直肠、胃底次之,十二指肠、回肠、食管中未发现VIP细胞。VIP细胞形态多样,呈椭圆形和锥体形,常有突起伸至其他细胞附近,也有突起直达上皮表面。
The distribution of vasoactive intestinal peptide（VIP） positive cells in the gastrointestinal tract of Laiwu black goat was compared and observed. The immunohistochemical method was used to show the distribution of VIP in the layers of various sections of gastrointestinal wall. The VIP positive cells were mostly distributed in the cardia, and then the colon, jejunum, pylorus, caecum, rectum and fundus; in the duodenum, ileum and esophagus,the VIP positive cells were not found. Moreover, the forms of VIP cells are diverse： some have the shapes as ellipse or cone, some extend up to other ceils nearby, and others to epidermic cells.
