Descending projections of substance P-and cholecystokinin-containing neurons of the periaqueductal gray and Edinger-Westphal nucleus to the spinal cord& a study with the combining method of tracing with immunocytochemistry 中脑导水管周围灰质和E-W核中SP和CCK样神经元至脊髓的投射&HRP与免疫细胞化学结合法研究
Projections from substance P ( SP)-and cholecystokinin ( CCK) containing neurons in the periaqueductal gray ( PAG) and Edinger-Westphal ( E-W) nucleus to the spinal cord were studied by means of the combining method of HRP tracing with immunocytochemistry in rats. 本研究用HRP逆行追踪和免疫细胞化学结合法,研究了大白鼠中脑导水管周围灰质(PAG)以及Edinger-Westphal(E-W)核至脊髓的SP能和CCK能神经投射。
