应用免疫过氧化物酶间接法,观察5只经蛛网膜下腔内注射秋水仙素的树鼩和10只未注射秋水仙素的树鼩脊髓C_5、T_3、T_9、L_4和S_25个节段内生长抑素样免疫反应阳性神经元的分布.结果表明,生长抑素样免疫反应在S_2最强,其次是L_4,灰质以后角最强,前角最弱.生长抑素样免疫反应阳性神经元胞体分布于脊髓后角和中间带,多数为小型(9～14μm)或中型(15～20μm)细胞.在S_2的中间带内有少数大型(20μm以上)多极细胞,其突起行向各方,有些突起上的膨体明显.阳性颗粒分布在神经元突起的根部和胞质的外周部.阳性纤维和终末主要分布于后角的边缘层和胶状质以及S_2的中间带.
Immunoperperoxidase indirect method was used to observe the effects of 5 sub-subarachnoid colchicine-injected tree shrews and 10 uncollected colchicine tree shrews on the C_5, T_3, T_9, L_4 and S_25 segments The results showed that somatostatin-like immunoreactivity was the strongest in S_2, followed by L_4, with the strongest angle after the gray matter and the weakest angle of anterior horn.The somatostatin-like immunoreactive neurons The majority of cells are small (9 ~ 14μm) or medium (15 ~ 20μm) cells distributed in the posterior horn and the middle of the spinal cord, with a few large (20μm or more) multipolar cells in the middle of S_2, , Some bulge bulge obvious positive particles distributed in the neuronal protuberance and the cytoplasm of the peripheral part of the positive fibers and terminal mainly in the posterior horn of the marginal layer and jelly and S_2 in the middle zone.
