摘要
实验选用170～210g的雄性Sprague-Dawley大鼠,侧脑室注入秋水仙素80～120μg,48小时后经左心室灌流固定,恒冷箱连续切片,厚5μm,每两个相邻的切片相对应,融表在两组载片上,分别用促肾上腺皮质激素释放因子抗血清(Anti-CRF)和神经降压素抗血清(Anti-NT)孵育,ABC或PAP免疫组织化学反应后,DAB呈色,检查、比较配对切片上免疫反应阳性细胞的位置和形态。结果,在相邻切片上看到卵圆核内有数量不等的位置相同、形态相似的免疫反应阳性细胞,即CRF-NT双标记或两种神经肽共存神经元。本组实验首次发现卵圆核内有CRF-NT共存神经元。
The oval nucleus of the bed nuclei of the stria terminalis of the rats was found in a previous investigation be studded with the corticotropin releasing factor (CRF) and neurotensin (NT)-immunoreactive(ir) neurons. The present work was to study their distribution and the possible coexistence of these two neuropeptides in the neuron of oval nucleus. The CRF- and NT- ir neurons were demonstrated to be densely and evenly distributed in the nucleus, among which were scattered a substantial number of cells cocontaining CRF and NT.
