摘要
采用兔抗哺乳类血清,应用链霉菌抗生物素蛋白-过氧化物酶免疫细胞化学技术,观察了锯缘青蟹视神经节中5 羟色胺、胰高血糖素、神经肽Y和生长抑素免疫阳性细胞和神经纤维的形态和分布,结果发现,视神经节的4个神经髓均有5 羟色胺免疫阳性细胞,除X器检出1个较大型阳性细胞外,其余均为小型细胞.视外髓、视内髓和视端髓都具有胰高血糖素免疫阳性细胞,视端髓的神经髓质阳性染色深,X器中阳性细胞成群分布,窦腺免疫阳性反应强.神经肽Y免疫阳性细胞在视神经层和视外髓为小型阳性细胞,在视内髓和视端髓检出较大型阳性细胞,另有小型阳性细胞散布于X器中.生长抑素免疫阳性细胞分布于4个神经髓,数量少. 4种免疫阳性物的特异性分布模式,可为其不同的神经生理作用提供形态学证据.
s: Immunocytochemistry technologies were applied to observe the immunoreactive neurons and neuropils of serotonin (5-HT), glucagon (Glu), neuropeptide Y (NPY) and somatostatin (SOM) in the optic ganglia of Scylla serrata. The results are as follows: 5-HT-immunoreactive cells are located in lamina ganglionaris(LG), medulla externa(ME), medulla interna(MI)and medulla terminalis(MT). Except one large immunoreactive cell in the X organ, the other immunoreactive cells are small. The presence of Glu-immunoreactive cells is found in the optic ganglia except LG. The immunoreactivity is strong in the neuropils of MT. Many immunoreactive cells in MT are aggregated in X organ. The sinus gland is immunoreactive. The NPY-immunoreactive cells are small in LG and ME and large in MI and MT. Small cells are also seen dispersing in the X organ. A few SOM-immunoreactive cells are distributed in the four neuropils in the optic ganglia. The specific distribution patterns of the four immunoreactive substances may thus supply morphological proofs for their different neurophysiological function.
