摘　　要：Using immunohistochemical method and double staining technique, the localization of growth hormone （GH） and somatostatin receptors in the nervous system and Hatschek＇s pit of amphioxus has been investigated. The results showed that the growth hormone like nerve cells and endocrine cells as well as three subtypes of somatostatin receptors exist in the nervous system and Hatschek＇ s pit, and GH like nerve cells and endocrine cells co-exist with three subtypes of somatostatin receptors in the brain vesicle and Hatschek＇s pit. It is suggested that a primitive control system of inhibitory growth hormone secretion in Hatschek＇s pit could have been developed in amphioxus, as in vertebrates. The present study provides new evidence for the endocrinology and the evolution of Hatschek＇s pit.用组织化学的方法和两倍染色的技术，生长荷尔蒙(GH ) 的本地化和在神经系统和 Hatschek 的 somatostatin 受体是的免疫，文昌鱼的坑被调查了。结果证明象 somatostatin 受体的三种子类型一样的像荷尔蒙的神经细胞和内分泌的细胞在神经系统和 Hatschek 退出的生长是坑，并且象 GH 一样神经细胞和内分泌的细胞在大脑泡和 Hatschek 的坑与 somatostatin 受体的三种子类型共存。在 Hatschek 的坑的禁止的生长荷尔蒙分泌物的一个原始控制系统能在文昌鱼被开发了，这被建议，作为在脊椎动物。现在的学习为内分泌学和 Hatschek 的坑的进化提供新证据。
