摘　　要：为了研究极北鲵(Salamandrella keyserlingii)皮肤的显微结构,采用苏木精-伊红染色法(Hematoxylin-eosin,HE)来进行研究。结果显示:极北鲵身体各处皮肤结构基本相同,均由表皮和真皮构成,但皮肤各处总厚度不同,躯干背部皮肤最厚、腹部最薄;在真皮层中还有大量的腺体存在,主要是粘液腺和颗粒腺,粘液腺以腹侧皮肤分布为主,颗粒腺以背侧皮肤分布为主,且颗粒腺较粘液腺大,此外,在躯干背侧皮肤中还发现有特殊粘液腺;色素细胞主要分布在真皮疏松层浅表;表皮下还有毛细血管分布。以上极北鲵皮肤结构的特点与其适应栖居潮湿生活环境有关。To study the microstructure of skin of Salamandrella keyserlingii, using paraffin section and hematoxylin-eosin staining. The results were as follows： the skin structures were basically the same as Salarnandrella keyserlingii throughout the body, compsed of epidermis and dermis. However, there were inter-position differences in skin thickness. The skin of the back was the thickest, the other of the abdomen was thinnest. Mucous and granular glands were rich in dermal, in the abdomen skin there were many mucous glands and in the dorsal skin there were many larger granular glands. Moreover, there were specialized mucous glands in dermal of the back. Dermal melanoeytes shallowly scattered mainly in dennis. The capillaries which under the epidermis were found. The skin structure of Salamandrella keyserlingii indicated its adaption to live in the moisture areas.
