用大鼠垂体冠状和矢状方向的连续切片，结合免疫组织化学方法详细地描述了ＳＰ－免疫阳性神经纤维在大鼠垂体前叶的分布特征。结果显示：簇状的ＳＰ－免疫阳性神经纤维在垂体前叶尾１／３段主要分布在背侧近垂体裂处；而在中１／３段则主要分布于前叶的两翼中部靠腹侧处。
The distribution of SP-immunoreactive nerve fibers in the anterior pituitary of rats was described in detail by serial sections of coronal and sagittal directions of the rat’s pituitary gland combined with immunohistochemical methods. The results showed that the clustered SP-immunoreactive nerve fibers mainly distributed in the dorsal and posterior pituitary fissures in the caudate 1/3 of the anterior pituitary and in the middle 1/3 of the anterior pituitary, Department.
