Some years ago, our group reported the presence of the female prostate in all the studied females of the plains viscacha (Lagostomus maximus). The goal of the present study was to characterize and compare the female prostate gland between adult pregnant and non-pregnant plains viscacha using histochemical, lectin-histochemical and immunohistochemical techniques, as well as optic and electron microscopy. Structurally, alveoli are lined by a simple epithelium formed by different cell types: basal cells, secretory cells in different stages of the secretory cycle and cells of clear cytoplasm. Secretory cells are the most abundant cell type, differing between them depending on the quantity and electron-density of their granules. The basal cells are less abundant and are responsible for the renewal of the alveolar epithelium. Likewise, other cells with secretory morphology were found in all the studied females; these have a clear cytoplasm, few granules and mitochondria. It could be considered that they are degranulated secretory cells or that they have partially released their granules. The stroma of the organ is formed by connective tissue and smooth muscle fibers, which are immunohistochemically evidenced against desmin. Histochemical and lectin-histochemical analysis revealed the presence of different glucidic residues in the different cell types. No structural, histochemical, lectin-histochemical, and ultrastructural differences were observed between pregnant and non-pregnant females of plain viscachas, except for the expression of some lectins. The paraurethral gland of Lagostomus maximus can be used as a model for studying the gland in other species since its structural and ultrastructural characteristics do not depend on the hormonal status of the female.

几年前，我们小组报告了所有研究的平原viscacha ( Lagostomus maximus）。本研究的目的是使用组织化学、凝集素组织化学和免疫组织化学技术以及光学和电子显微镜来表征和比较成年妊娠和非妊娠平原 viscacha 之间的女性前列腺。在结构上，肺泡内衬由不同细胞类型形成的简单上皮：基底细胞、处于分泌周期不同阶段的分泌细胞和透明细胞质的细胞。分泌细胞是最丰富的细胞类型，它们之间的差异取决于其颗粒的数量和电子密度。基底细胞数量较少，负责肺泡上皮的更新。同样，在所有研究的雌性中都发现了具有分泌形态的其他细胞。它们具有清晰的细胞质、很少的颗粒和线粒体。可以认为它们是脱颗粒的分泌细胞或者它们已经部分释放了它们的颗粒。器官的基质由结缔组织和平滑肌纤维形成，免疫组化证明其对抗结蛋白。组织化学和凝集素-组织化学分析揭示了不同细胞类型中存在不同的糖苷残基。除了一些凝集素的表达外，在怀孕和未怀孕女性之间没有观察到结构、组织化学、凝集素-组织化学和超微结构差异。尿道旁腺 组织化学和凝集素-组织化学分析揭示了不同细胞类型中存在不同的糖苷残基。除了一些凝集素的表达外，在怀孕和未怀孕女性之间没有观察到结构、组织化学、凝集素-组织化学和超微结构差异。尿道旁腺 组织化学和凝集素-组织化学分析揭示了不同细胞类型中存在不同的糖苷残基。除了一些凝集素的表达外，在怀孕和未怀孕女性之间没有观察到结构、组织化学、凝集素-组织化学和超微结构差异。尿道旁腺Lagostomus maximus可用作研究其他物种腺体的模型，因为其结构和超微结构特征不取决于雌性的荷尔蒙状态。
