摘要： 为了研究繁殖期东北林蛙两性皮肤组织结构的差异，应用苏木精-伊红(Hematoxylin-eosin Stain，HE)染色方法对东北林蛙两性皮肤组织结构进行研究。结果显示：两性皮肤的总厚度在头、躯干背、腹部存在极显著差异(P<0.01)，其中背部皮肤雌性比雄性厚，腹部皮肤雄性比雌性厚；躯干侧部皮肤雄性比雌性厚，且二者之间有显著差异(P<0.05)；皮肤各部均有颗粒腺和粘液腺分布，且颗粒腺较粘液腺大，此外在雄性背部皮肤中还发现有特殊粘液腺。上述东北林蛙两性皮肤的结构特点与其生殖、呼吸以及防御功能有关。

Abstract: To study the comparative histological observation of skin in male and female frog (Rana dybouwskii) during breeding season, using paraffin section and hematoxylin-eosin staining. The results showed that: there were significant differences between male and female frogs in the types of total thicknesses of the head and the trunk dorsum and abdomen. The dorsal in females was extremely thicker than in males. The abdominal in males was highly significant thicker than in females. In males the lateral trunk was significantly thicker than in females. There were two kinds of glands present, namely mucous glands and granular glands and they were found throughout the skin of the body. Typical granular glands were larger than mucous glands. In addition, we observed the type of the specialized mucous glands in males. It might be related to the reproduction, breath, and defense functions.
