Abstract
In the feline gastrointestinal tract, the neuropeptides, substance P, VIP and PHI were investigated by specific radioimmunoassays and immunocytochemistry. The concentrations of all 3 peptides and the level of peptidergic innervation were significantly less in the anal sphincter than elsewhere, whereas no significant differences were seen between other sphincter and non-sphincter regions.
摘要
在猫的胃肠道中，通过特异性放射免疫分析和免疫细胞化学方法对神经肽、P物质、血管活性肠肽（VIP）和胰高血糖素样肽I（PHI）进行了研究。在肛门括约肌中，这三种肽的浓度以及肽能神经支配水平均显著低于其他部位，而在其他括约肌和非括约肌区域之间未观察到显著差异。
