| 摘 要： | 采用光镜和扫描电镜,对我国特有的珍稀濒危两栖动物版纳鱼螈Ichthyophis bannanicus幼体和成体的皮肤进行形态学和组织学观察.版纳鱼螈幼体和成体的皮肤均可分为表皮、真皮疏松层和真皮致密层;皮肤中含有粘液腺和颗粒腺;在不同发育阶段或同一个体的不同部位,其皮肤的各种组成成分在结构和厚度上存在着差异:成体和幼体都是头部的表皮最厚,尾部的最薄;幼体表皮各层细胞分化不明显,几无角化现象,成体表皮的各层细胞分化明显,表层细胞明显角化;成体躯干部皮肤最厚,头部最薄,幼体则是头部皮肤最厚,尾部最薄;幼体和成体的头部皮肤都分布有大量的粘液腺,颗粒腺分布较少;幼体的躯干部皮肤则主要分布着大量颗粒腺,尾部只有颗粒腺,未见粘液腺;成体躯干部和尾部皮肤均分布有大量的颗粒腺和粘液腺. |

| Abstract: | The morphological and histological observation on the skin of larval and adult Ichthyophis bannanicus,which is endemic and endangered amphibian in China,was studied by optical and scanning electron microscope.The results showed that both the skin of larval I.bannanicus and that of adult were composed of epidermis,dermis osteoporosis layer and dermal dense layer.There were mucus glands and particle glands in the skin.The various components of its skin were different in structure and thickness in both differe... |
