Harderian glands from male and female Octodon degus were examined by light and transmission electron microscopy. Two types of secretory units, designated as type I and type II, were observed. Type I secretory units comprise three types of epithelial cells: Cells packed with numerous lipid droplets (Type a), cells with few lipid droplets (Type b), and cells with numerous mitochondria and a very well developed Golgi complex (Type c). Type II secretory units were found exclusively in female Octodon degus and comprised a type of secretory cells which contained numerous basophilic granules in their apical cytoplasm. In addition, in female Octodon degus, clusters of lymphocyte-like cells and plasmatic cells were also observed. The vascularization of the gland appeared very well developed. The most unique feature of the blood supply was the existence of large sinusoidal vessels extremely variable in shape. In the medullar region, the sinsoidal wall adapts its contour to that of the tubuloalveolar surface. Unmyelinated and myelinated nerve fibers were found in the connective stroma of the gland.
对雄性和雌性八齿鼠的哈德氏腺进行了光镜和透射电镜检查。观察到两种类型的分泌单位，分别命名为I型和II型。I型分泌单位由三种类型的上皮细胞组成：充满大量脂滴的细胞（a型）、含少量脂滴的细胞（b型）以及含有大量线粒体和非常发达的高尔基体复合体的细胞（c型）。II型分泌单位仅在雌性八齿鼠中发现，由一种在顶端细胞质中含有大量嗜碱性颗粒的分泌细胞组成。此外，在雌性八齿鼠中还观察到淋巴细胞样细胞和浆细胞簇。该腺体的血管化似乎非常发达。血液供应最独特的特征是存在形状极其多样的大窦状血管。在髓质区域，窦状壁的轮廓与小管泡状表面的轮廓相适应。在腺体的结缔组织基质中发现了无髓和有髓神经纤维。
