摘　　要：本研究用免疫组织化学方法,研究了人和猴、犬、猫及大鼠等4种动物垂体后叶中甘丙肽免疫阳性神经纤维的比较分布。甘丙肽阳性纤维在犬和大鼠垂体后叶密度最高,猴和猫次之,人类最低。人和猴垂体柄与神经叶交界处的前部边缘区,甘丙肽阳性纤维在局部呈非常高密度分布,内侧中央区为稀疏至中等密度。犬和大鼠呈弥散分布;犬垂体后叶的后部,有纤维增密现象。猫以垂体隐窝周区密度最高。人和猫垂体后叶可见串珠样甘丙肽阳性纤维;猴为中等粗细、串珠样和膨体型3种类型;大鼠则为细纤维和膨体型两种纤维;犬则可见4种类型的纤维。4种动物和人垂体后叶周边区都有纤维增多或形成纤维丛的现象。一些纤维穿行于血管壁周围。Comparative investigation of the distribution of galanin-immunoreactive (GAL-ir) nerve fibers in the neural lobe of the human being, monkey, dog, cat and rat was studied immunohistochemically. The density of GAL-ir fibers in the posterior pituitary was highest in the dog and rat, moderate in the monkey and cat; and lowest in the human being. A dense accumulation of positive fibers appeared in the pituitary stalk bordoring the intermediate lobe. The fiber density in the central part of the posterior pituitary was slightly higher than at its periphery in the human and monkey. Moderate amount of fibers were found to spread all over the neural lobe of the dog and rat, with slightly higher density in the posterior part of the dog. In the cat, the highest density of GAL-ir fibers was found along the wall of the recess hypophysis. A slightly increasing fibers or fiber clumps were seen in the peripheral region of posterior pituitary in four species of the animals and human being. Some fibers were found surrounding the blood vessels or located in their walls.
