本研究用大白鼠12只,于脊髓颈膨大 (8例) 和腰膨大 (4例) 处背中线右侧,3点分别注射50％HRP水溶液,总量为0.6—1.5微升。在脑干内看到HRP标记细胞,分布如下: 1.延髓:巨细胞网状核,旁正中网状核,外侧网状核,中缝苍白核,中缝隐核,三叉神经脊束核,孤束核和下橄榄核等。 2.脑桥:桥吻侧网状核,桥尾侧网状核、中缝大核,前庭神经核、兰斑核、三叉神经主核。 3.中脑:中缝背核,中线核,艾一维氏 (E—M核) 核,被盖腹侧核,楔核、上、下丘核,红核和黑质。
In this study, 12 rats were injected with 50% HRP solution in the right dorsal line of the dorsal midline of cervical enlargement (8 cases) and lumbar enlargement (4 cases), with the total amount of 0.6-1.5 microliters. The HRP-labeled cells are seen in the brainstem and are distributed as follows: 1. Medulla oblongata: giant cell reticular nucleus, mesial reticular nucleus, lateral reticular nucleus, mesencephalic pale nucleus, synovectomy, trigeminal nucleus, Nuclear and olive under the core. 2. Pons: bridge kiss side reticular nucleus, bridge caudal reticular nucleus, nucleus raphe magnus, vestibular nucleus, blue spot nucleus, the main trigeminal nerve. 3. Midbrain: dorsal raphe, midline, E-M nuclear, covered ventral, wedge, superior, inferior, red nucleus and substantia nigra.
