Abstract
High concentrations of neuropeptide Y (NPY) have been demonstrated in the gall bladder (16.7 +/- 5.4 pmol/g), cystic duct (25.4 +/- 9.2 pmol/g) and common bile duct (54.7 +/- 11.5 pmol/g) of the guinea-pig using a recently developed radioimmunoassay. Immunoreactive NPY containing nerves were demonstrated in all layers of the biliary tree using immunocytochemistry, being particularly dense in the myenteric and mucosal plexuses.
摘要
使用最近开发的放射免疫分析法已证实，豚鼠的胆囊（16.7±5.4皮摩尔/克）、胆囊管（25.4±9.2皮摩尔/克）和胆总管（54.7±11.5皮摩尔/克）中存在高浓度的神经肽Y（NPY）。利用免疫细胞化学方法在胆道树的所有层中均证实了含有免疫反应性NPY的神经，在肌间神经丛和黏膜神经丛中尤为密集。
