摘　　要：以斑马鱼早期胚胎为研究对象,通过免疫组织化学的方法研究了超氧化物歧化酶(SOD)在斑马鱼体节分化时期的表达特点。结果发现:在体节分化的不同时期,SOD在脊索细胞的胞质部位有不同强度的表达;SOD在脑组织中表达较强,到孵化期,在大脑区域的表达略强于间脑区域。提示SOD不仅存在于成体的抗氧化防线中,在胚胎早期发育过程中以SOD为代表的酶性抗氧化系统就开始逐步建立,维持胚胎组织器官细胞中的正常活性氧浓度,确保胚胎的正常发育。This projet is probed into know how the superoxidase dismutase distribute in Danio rerio em- bryo at segmentation stage by immunohistochemistry method. The result showed at segmentation stage, superoxidase dismutase was expressed in different intensity in Pharyngula and brain and other tissue. The result suggested superoxidase dismutase was an important antioxidase enzyme in embryo developing, and the antioxidase system was established at the developing stage. The enzyme-antioxidase system was first antioxidase line set up to protect embryo.
