大多数哺乳动物物种都有一个犁鼻器，可以检测特定的化学物质，如信息素。覆盖犁鼻感觉上皮的粘液由犁鼻腺分泌，这些液体的性质被认为与化学检测有关。组织学研究，使用高碘酸希夫（PAS）和Alcian蓝pH 2.5（AB）染色，分别检测天然和酸性多糖，表明犁鼻腺物种之间的性质的变化。在这里，我们调查了犁鼻腺PAS和AB染色在8个Laurasiatheria物种的反应。本文研究的所有物种都具有犁鼻腺PAS染色阳性，像其他许多报道的物种。犬和水貂样啮齿动物犁鼻腺AB阴性，牛、山羊、西卡鹿、麝和两种蝙蝠犁鼻腺AB阳性。考虑到目前的研究结果和以前的报告，犁鼻腺在大多数的Laurasiatheria物种似乎是从根本上丰富的酸性多糖，而那些在食肉动物基本上含有中性多糖。
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.
