Most mammalian species have a vomeronasal organ that detects specific chemical substances, such as pheromones. Mucous fluid covering the vomeronasal sensory epithelium is secreted by vomeronasal glands, and the properties of these fluids have been suggested to be involved in chemical detection. Histological studies using periodic acid-Schiff (PAS) and Alcian blue pH 2.5 (AB) stains, which respectively detect natural and acidic polysaccharides, have suggested variations in the nature of the vomeronasal glands among species. Here, we investigated the responsivity of the vomeronasal glands to PAS and AB stains in eight Laurasiatheria species. All species studied herein possessed vomeronasal glands that stained positive for PAS, like other many reported species. The vomeronasal glands of dogs and minks - like rodents, were AB-negative, whereas those of cows, goats, sika deer, musk shrews and two bat species were positive. Considering the present findings and previous reports, the vomeronasal glands in most of Laurasiatheria species appear to be fundamentally abundant in acidic polysaccharides, whereas those in carnivores essentially contains neutral polysaccharides.

比较的组织学研究的八个月桂草属物种的犁鼻鼻腺分泌的多糖的特性。

大多数哺乳动物物种的犁鼻器官都会检测特定的化学物质，例如信息素。覆盖鼻腔感觉上皮的粘液是由鼻腔腺分泌的，这些液体的性质已被认为与化学检测有关。使用高碘酸席夫（PAS）和Alcian blue pH 2.5（AB）染色的组织学研究分别检测天然和酸性多糖，表明物种间犁鼻鼻腺的性质存在差异。在这里，我们调查了八种Laurasiatheria物种中的犁鼻腺对PAS和AB染色的反应性。与其他许多物种一样，本文研究的所有物种均具有PAS染色呈阳性的犁鼻鼻腺。象啮齿动物一样，狗和水貂的鼻前腺是AB阴性的，牛，山羊，梅花鹿，麝香和两种蝙蝠则为阳性。考虑到目前的发现和以前的报道，大多数Laurasiatheria物种的犁鼻鼻腺在酸性多糖中似乎基本丰富，而在食肉动物中则基本上含有中性多糖。
