采用 PAP 免疫组织化学方法,对心房利钠肽样免疫反应神经元在大鼠动眼神经核和三叉神经运动核内的分布的研究表明:一定数量的大型和中型(以大型为主)多极的 ANP 样免疫反应神经元分别存在于动眼神经核和三叉神经运动核内,细胞呈多角形、三角形或卵圆形。在动眼神经核内,阳性胞体以核的腹内侧部最多,背外侧部次之,中央部很少。在三叉神经运动核内,阳性胞体分布于核的中央和背侧部。在两核内的阳性胞体之间均分别含有一些阳性纤维。结果提示:脑内ANP 可能在调节眼外肌和咀嚼肌的随意运动和反射活动中起着一种神经调质的作用。
Using PAP immunohistochemistry to study the distribution of atrial natriuretic peptide-like immunoreactive neurons in the oculomotor nucleus and trigeminal motor nucleus in rats shows that a certain number of large and medium (mainly large) multipoles Of ANP-like immunoreactive neurons were present in the oculomotor nucleus and trigeminal motor nucleus, the cells were polygonal, triangular or oval. In the oculomotor nucleus, the positive cell bodies to the nucleus of the ventral side of the largest, followed by the dorsolateral part of the central ministry. In the trigeminal motor nucleus, positive soma is distributed in the central and dorsal part of the nucleus. Positive nuclei within the two nuclei each contain some positive fibers. The results suggest that ANP may play a role in neuromodulation in the regulation of the voluntary movement and reflex activities of extraocular and masticatory muscles.
