Abstract
The cholecystokinin (CCK) concentration in individual brain stem nuclei of rat was determined using the Palkovits punch method19 and the CCK RIA3, CCK has a unique distribution in the brain stem, unlike other neuropeptides and biogenic amines8,19. In general, the CCK levels in the brain stem are 5-20% of rat cerebral cortex. The colliculi, midbrain central gray, nucleus of the solitary tract, and the interpeduncular nucleus had the highest CCK content (2.7-1 ng CCK mg protein).
摘要
采用帕尔科维茨打孔法19和胆囊收缩素放射免疫分析法3测定大鼠各个脑干核团中的胆囊收缩素（CCK）浓度。与其他神经肽和生物胺8,19不同，CCK在脑干中具有独特的分布。一般来说，脑干中的CCK水平是大鼠大脑皮层的5%-20%。中脑、中脑中央灰质、孤束核和脚间核的CCK含量最高（2.7-1 ng CCK/毫克蛋白质）。
