| 摘 要： | 运用透射电镜技术对采自浙江的日本医蛭和天目山蛭的光感受器-眼的超微结构进行了比较研究.发现两者的主要差别在于前者眼的色素杯浅,且宽度与深度较为接近,透光体微绒毛可卷曲;后者眼的色素杯深,其深度明显大于宽度,透光体微绒毛未见卷曲.天目山蛭感光细胞中由微绒毛组成的感光膜表面积远大于日本医蛭,因此陆生蛭类的感光能力比水生种类强,这与陆地环境的复杂性有一定关系.

| Abstract: | The ultrastructure of eyes in Hirudo nipponia from Wuyi County in Zhejiang Province and Haemadipa tianmushana from West Tianmushan in Zhejiang was studied. In eyes of Hir. nipponia, the pigment cup is shallow, and submicrovilli of the vitreous body in photoreceptive cell may crisp. The pigment cup of Hae. tianmushana is deeper, and submicrovilli of the vitreous body in photoreceptive cell aren't may crisp. The surface area of the microvillar membrane of photoreceptive cell in Hae. tianmushana is much larger than that in Hir. nipponia. |
