Neural lobes from rats subjected to neurohypophysial hormone-releasing stimuli were examined electron microscopically following fixation in 4% tannic acid in 2.5% glutaraldehyde. This fixation allowed the delineation of the perivascular space in the neural lobe tissue. Measurement of the area of the perivascular space showed that it was significantly increased in the rats subjected to vagal stimulation and intraarterial calcium ions compared to the control rats. The rats which had been subjected to haemorrhage as a hormone-releasing stimulus did not show any significant change in the area of the perivascular space. The significance of these findings in relation to hormone release is discussed.
将接受神经垂体激素释放刺激的大鼠的神经叶，在4%鞣酸于2.5%戊二醛中固定后进行电子显微镜检查。这种固定方法能够清晰显示神经叶组织中的血管周围间隙。对血管周围间隙面积的测量表明，与对照大鼠相比，接受迷走神经刺激和动脉内注射钙离子的大鼠，其血管周围间隙面积显著增加。作为激素释放刺激而接受出血处理的大鼠，其血管周围间隙面积未显示出任何显著变化。本文讨论了这些发现与激素释放相关的意义。
