The bulbourethral glands of 2-month-old calves were studied by means of lectin histochemical methods. The lectin-binding sites for each considered lectin can be divided into three groups according to their zonal topography. In the first group including PNA, MPA, RCAI, SBA and BPA binding sites were seen in most of the secreting tubules and end pieces. In the second group (WGA, GSI, DBA, UEAI and Con A) the reactive cells were limited to a reduced number of tubuloalveolar units generally located at the periphery of the gland. The third group was composed of two lectins, GSII and LTA for which the bulbourethral parenchyma was unreactive. These findings can be related to the glandular activity of the calf bulbourethral gland except for restricted peripheral areas with an appearing functional differentiation. This duality in the histochemical nature of glycoconjugates was compared with previous results obtained in other groups of mammals.
采用凝集素组织化学方法对2月龄犊牛的尿道球腺进行了研究。根据其区域分布，每种凝集素的凝集素结合位点可分为三组。第一组包括PNA、MPA、RCAI、SBA和BPA，其结合位点可见于大多数分泌小管和终末小管。第二组（WGA、GSI、DBA、UEAI和Con A）中的反应性细胞仅限于数量减少的管状腺泡单位，这些单位通常位于腺体周边。第三组由两种凝集素组成，即GSII和LTA，尿道球腺实质对其无反应。除了具有明显功能分化的受限周边区域外，这些发现可能与犊牛尿道球腺的腺体活动有关。将糖缀合物的这种组织化学性质的二元性与其他哺乳动物组先前获得的结果进行了比较。
