脑干中央上核传入纤维的起源及其与针刺镇痛的关系

Afferent Projections to the Central Superior Raphe Nucleus of Brain Stem and Its Relation to Acupuncture Anesthesia

本文用HRP逆行追踪法研究了大白鼠脑干中央上核传入纤维的来源。将3％WGA－NRP0．05～0．10μl注入11只大白鼠的中央上核内。标记细胞出现于缰外侧核内侧部、下丘脑后区、脚间核外侧亚核、中缝背核、中脑导水管周围灰质腹外侧部、舌下神经前置核、背侧旁正中核、背侧旁巨细胞网状核、中缝大核和小脑顶核。为研究中央上核的功能提供形态学依据。

The afferent projections to the central superior raphe nuclus' (CS) in the rat were investigated bymeans of HRP retrograte tracting method. 3% WGA-HRP 0. 05-0. 1μl was injected into the CS ineach of 11 rats. The labeled cells were found in the medial part of lateral habenular nucleus, posteriorhypothalarnic area l lateral subnucleus of interpeduncalar nucleus, dorsal raphe nucleus, periaqueductalgray matter dorsal paramedial nucleus, preposital hypoglossal nucleus, dorsal paragiganto-cellularnucleus. magnum raphe nucleus, and fastigatum of cerebellum- The results provide morphological ba-sis for researching function of the CS in acupuncture anesthesia.
