The mandibular glands of Dasyuroides byrnei were examined by light microscopy, and transmission and scanning electron microscopy. The secretory units consisted of numerous seromucous acini and a few seromucous demilunes. The seromucous acini were almost always capped by demilunes. The acinar seromucous cells contained faintly basophilic, light, coarse, bipatite secretory granules with matrix of low and moderate densities. The demilunar cells were dark compared with acinar seromucous cells and contained acidophilic secretory granules with a fibrillogranular matrix of moderate density. Preacinar cells with a seromucous nature were occasionally present at the junction between the acinus and intercalated duct. These cells had numerous basophilic granules, which were similar to those of acinar seromucous cells. The intercalated ducts consisted of simple cuboidal light cells that had a few small electron-dense granules. The striated ducts were composed of tall columnar light cells containing numerous vesicles, but no secretory granules. The mandibular acini of D. byrnei were composed of two cell types having a seromucous nature, unlike those of the opossum and many other mammals.
通过光学显微镜、透射电子显微镜和扫描电子显微镜对拜氏袋鼬的下颌腺进行了检查。分泌单位由大量的浆液黏液性腺泡和少数浆液黏液性半月体组成。浆液黏液性腺泡几乎总是被半月体覆盖。腺泡浆液黏液细胞含有淡嗜碱性、浅色、粗大的双叶分泌颗粒，其基质密度低和中等。与腺泡浆液黏液细胞相比，半月体细胞颜色较深，含有嗜酸性分泌颗粒，其纤维颗粒状基质密度中等。在腺泡和闰管之间的连接处偶尔会出现具有浆液黏液性质的腺泡前细胞。这些细胞有许多嗜碱性颗粒，与腺泡浆液黏液细胞的颗粒相似。闰管由简单的立方浅色细胞组成，这些细胞有一些小的电子致密颗粒。纹状管由高柱状浅色细胞组成，含有许多小泡，但没有分泌颗粒。与负鼠和许多其他哺乳动物不同，拜氏袋鼬的下颌腺泡由两种具有浆液黏液性质的细胞类型组成。
