| 中文摘要: |
| 为探讨家鸽、毛腿沙鸡和灰斑鸠视网膜组织结构与其生活环境适应的关系,用光镜观察了3种动物视网膜的组织结构,测量了3种动物视网膜各层厚度、3个核层的胞核层数及胞核直径。用免疫组化观察了NogoC蛋白在3中动物视网膜的表达情况。结果表明:家鸽、毛腿沙鸡和灰斑鸠视网膜均由4层细胞构成,在显微镜下分为10层。家鸽、毛腿沙鸡和灰斑鸠视网膜平均厚度分别为416.29、437.90、419.36 μm。毛腿沙鸡视网膜内核层和节细胞层的层数比家鸽和灰斑鸠的多,视细胞数亦较家鸽和灰斑鸠的多。毛腿沙鸡和灰斑鸠视网膜内核层、内网层、节细胞层和神经纤维层4层厚度所占总厚度比例(分别为69.77%、68.05%)要比家鸽(49.97%)的高。表明毛腿沙鸡具有比家鸽和灰斑鸠更强的视觉分辨能力和对强光的适应能力,毛腿沙鸡和灰斑鸠的视神经要比家鸽的发达。NogoC蛋白在正常状态下视网膜中的表达可能发挥某些特定的生理作用,但还需进一步研究。 |
| 英文摘要: |
| To explore the relationship between retinal structure and its life adaptation to the environment, the retinal structure of Aplopelia bonaparte, Syrrhaptes paradoxus and Streptopelia decaocto was observed by light microscope, and the retinal thickness of each layer, the nuclei layer and the diameter of three nuclear layers of three animals were measured. Immunohistochemical analysis was used to determine NogoC protein expression in retinas. The results showed that the nuclei layers of three animals were all four layers and the lens were ten layers. The retinal thickness of them was 416.29, 437.90 and 419.36 μm respectively. The layer number and cell count in retinal inner nuclear layer and ganglion cell layer of S. paradoxus were more than those of the other two animals. S. paradoxus and, S. decaocto's proportions of thickness of four layers (inner nuclear layer, inner plexiform layer, ganglion cell layer and nerve fiber layer) accounting for total thickness of retina were 69.77% and 68.05%, respectively, which were higher than that of A. bonapart (49.97%). The evidence indicated that the abilities of visual discrimination and adapting strong light of S. paradoxus were stronger than those of the other two animals, and the optic nerves of S. paradoxus and S. decaocto were more developmental than those of A. bonapart. NogoC protein expression in retinas may play an important role in physiological function, but still need further study. |
