大鼠蓝斑至伏核的SP能上行投射

Substance p-ergic projections from locus ceruleus to nucleus accumbens in rats

采用ＨＲＰ逆行追踪和免疫细胞化学ＰＡＰ法相结合，对蓝斑至伏核的上行投射通路进行了研究。结果表明：同侧蓝斑有ＳＰ能神经元上行投射到伏核。ＨＲＰ－ＳＰ双标记投射神经元占有ＨＲＰ标记投射神经元的５０％

he projections from the locus ceruleus to the nucleus accumbens in rats were studied by using a double-labeling method of HRP retrograde tracingcombined with PAP immunocytochemistry. Results showed that there weresome substance p-like immunoreactive neurons in the locus ceruleus to sendaxons to the nucleus accumbens and the number of the HRP-SP double la- beling neurons accounted for 50% of the HRP Iabeling neurons.
