Both the apocrine and the sebaceous portions of the infraorbital gland of the Japanese serow were examined to obtain morphological evidence related to the mechanism of secretion. The examination was carried out by an immunohistochemical method using antibodies against alpha-smooth muscle actin for myoepithelial cells and protein gene product 9.5 for nerve fibers. Immunostaining for alpha-smooth muscle actin was apparent in the myoepithelial cells of apocrine tubules and varied within the same glands and among individual glands. Immunostaining for protein gene product 9.5 revealed the presence of nerve fibers around apocrine tubules. The immunoreactive nerve fibers were fine or varicose. In the sebaceous glands of the ordinary type and of the modified type, no immunoreactivity specific for alpha-smooth muscle actin or protein gene product 9.5 was observed. These results suggest that apocrine tubular activity of the infraorbital gland occurs independently in each tubule and that secretion by the apocrine tubules is controlled by the myoepithelial cells via nerve fibers.
对日本鬣羚眶下腺的顶泌腺和皮脂腺部分进行了检查，以获取与分泌机制相关的形态学证据。通过免疫组织化学方法进行检查，使用抗α平滑肌肌动蛋白的抗体检测肌上皮细胞，使用抗蛋白基因产物9.5的抗体检测神经纤维。α平滑肌肌动蛋白的免疫染色在顶泌腺小管的肌上皮细胞中明显可见，且在同一腺体和不同个体腺体之间存在差异。蛋白基因产物9.5的免疫染色显示顶泌腺小管周围存在神经纤维。免疫反应性神经纤维纤细或呈曲张状。在普通型和改良型皮脂腺中，未观察到对α平滑肌肌动蛋白或蛋白基因产物9.5具有特异性的免疫反应性。这些结果表明，眶下腺的顶泌腺小管活动在每个小管中独立发生，并且顶泌腺小管的分泌由肌上皮细胞通过神经纤维控制。
