The venom glands of the western spade-foot toad Pelobates cultripes were studied under light and electron microscopes. The glands exhibit the structural patterns usual in anurans, including the typical secretory syncytium. The peripheral cytoplasm contains a single row of nuclei and secretory organelles related to proteosynthesis. The inner cytoplasm is filled with large vesicles holding a thin product which originates from the merging of smaller ones containing a thicker material derived from the Golgi apparatus. The appearance and maturation of P. cultripes venom have been compared with patterns of biosynthesis and secretory evolution described in serous cutaneous glands of several anuran species. Following these criteria, the traditional trends in the terminology and classification of serous glands in anuran skin are discussed and reviewed.
在光学显微镜和电子显微镜下对西方锄足蟾（Pelobates cultripes）的毒腺进行了研究。这些腺体呈现出无尾两栖类动物常见的结构模式，包括典型的分泌性合胞体。外周细胞质含有一排细胞核和与蛋白质合成相关的分泌细胞器。内部细胞质充满了大囊泡，囊泡中含有一种稀薄的产物，该产物源于较小囊泡的融合，较小囊泡中含有来自高尔基体的较浓稠物质。已将西方锄足蟾毒液的外观和成熟过程与几种无尾两栖类动物浆液性皮肤腺中描述的生物合成和分泌进化模式进行了比较。根据这些标准，对无尾两栖类动物皮肤浆液性腺体术语和分类的传统趋势进行了讨论和综述。
