本文用PAP法研究了Serotonin样,Substance P样,Leucine—Enkephalin样和Methionine—Enkephalin样反应阳性神经元胞体在大鼠中缝核簇内的分布。证明Serotonin存在于中缝苍白核、中缝隐核、中缝大核、中缝桥核、中央上核和中缝背核等处的某些神经元胞体内。以中、小细胞为主,在中缝大核内有少数大细胞。细胞形态为梭形、圆形、卵圆形以及多极细胞。Substance P样反应阳性胞体在上述中缝核内也被发现,其胞体的大小、形态和分布与serotonin样反应阳性胞体相似,但数目稍少。Leucine—Enkephalin样反应阳性胞体存在于中缝苍白核、中缝隐核、中缝大核、中缝桥核、中缝背核和中央上核内,但Methionine—Enkephalin样反应阳性细胞体仅在中缝苍白核和中缝隐核的吻侧部以及中缝大核内发现。后两者均以大,中型多极细胞为主。
In this paper, the distribution of Serotonin-like, Substance P-like, Leucine-Enkephalin-like and Methionine-Enkephalin-like reactive neuronal somatic bodies in the rat raphe nucleus was investigated by PAP method. Serotonin proves that there are some neurons in the pale stapes, stapes of the middle stapes, stapes of the meridian, meso-stratum, mesencephalic nucleus, dorsal raphe nucleus and so on. Small and medium-sized cells in the main stalk, there are a few large cells in the stapes. Cell morphology is fusiform, circular, oval and multipolar cells. Substance P-like positive cells were also found in the above-mentioned mesenchymal nucleus. The size, shape and distribution of the somatic cells were similar to those of serotonin-like positive cells, but their numbers were slightly smaller. Leucine-Enkephalin-like positive cell bodies present in the pale sepal, meso septal, meso-mesenchyme, mezzanine bridge, meridian dorsal nucleus and central superior mesenchyme but Methionine-Enkephalin-like positive cell bodies only in the pale seams and the middle seams Hidden nucleus of the kiss and the side of the big nucleus found. The latter two are large and medium-sized multipolar cells.
