摘要
用免疫细胞化学(ABC)方法观察了鸡低位脑干内生长抑素(SS)样成份的分布。不同密度的SS样神经元胞体存在于脚间核、中脑中央灰质、线形尾侧核、视顶盖、脑桥被盖、小细胞网状核、孤束核和延髓网状结构;此类细胞均为中、小型(5~21μm),形状多样。SS样纤维存在于中脑顶盖前区、动眼神经根邻近的内外侧区、脚间核及其腹外侧区、中脑网状结构、视顶盖、脑桥嘴侧网状结构、斜方体、上橄榄核及延髓网状结构;零散的此类纤维在低位脑干多处可见。表明鸡低位脑干内SS样成份的分布与哺乳类不完全相同。
With immunocytochemical ABC technique, the distribution of somatostatin(SS)-like immunoreactivities in the lower brain stem of the chicken was explored. SS-positive neuron bodies were localized in nucleus interpeduncularis, periaqueductal central grey and the adjacent reticular formation lateral to it, nucleus linearis caudalis, tectum opticum, pontine tegmentum, nucleus reticularis parvocellularis, formatio reticularis medullaris and nucleus tractus solitarii. The SS-neuron bodies were small to medium (5~12μm) and varied in shape. SS-fibers and terminal were localized in area pretectalis, inner and lateral area of occulomotor nerve root, ventrolateral area of nucleus interpeduncularis, tectum opticum, nucleus olivais superior and formatio reticularis; Odd SS-fibers could be seen in many parts of the brain stem. The results show that the distribution of SS-like positive reactivities are not same to that of the mammals, notable exceptions exist.
