The mandibular glands of the Chinese hamster were examined by light and electron microscopy. The mandibular acinar cells were noted to be categorized in a seromucous type, because the acinar cells stained slightly basophile and moderately positive for periodic acid-Schiff (PAS) and alcian blue (AB) reactions and the intercellular canaliculi were detected in the cells. The acini were composed exclusively of light cells containing various secretory granules. The acinar cells exhibited a sexual dimorphism; in the female AB staining was more intense, and also the granules having the matrix of a fine hair-like material were more numerous than in the male. Intercalated duct cells were composed exclusively of light cells and contained round and polygonal granules. The striated ducts consisted of two distinct portions, the secretory and typical striated portions without secretory granules. The epithelial cells of secretory portion were columnar in shape and contained acidophile granules which gave a strongly positive PAS reaction, and comprised light and dark cells containing secretory granules varying in size and density. The epithelium of typical striated portion was composed of both light and dark cells containing fine vacuoles and vesicles, but no secretory granules. No sexual dimorphism was detected in the striated duct.
通过光学显微镜和电子显微镜对中国仓鼠的下颌腺进行了检查。下颌腺泡细胞被归类为浆液黏液型，因为腺泡细胞呈轻度嗜碱性染色，对过碘酸希夫（PAS）反应和阿尔辛蓝（AB）反应呈中度阳性，并且在细胞中检测到细胞间小管。腺泡仅由含有各种分泌颗粒的亮细胞组成。腺泡细胞表现出性别二态性；在雌性中，AB染色更强烈，并且具有细毛状物质基质的颗粒比雄性更多。闰管细胞仅由亮细胞组成，含有圆形和多边形颗粒。纹状管由两个不同部分组成，即分泌部分和无分泌颗粒的典型纹状部分。分泌部分的上皮细胞呈柱状，含有嗜酸性颗粒，PAS反应呈强阳性，由含有大小和密度不同的分泌颗粒的亮细胞和暗细胞组成。典型纹状部分的上皮由含有细小空泡和小泡的亮细胞和暗细胞组成，但没有分泌颗粒。在纹状管中未检测到性别二态性。
