Specimens from normal human parotid, submandibular and minor salivary glands were processed for electron microscopy. Myoepithelial cells were readily identified by previously reported ultrastructural features. Electronmicrographs were subjected to stereological analysis and the percentage volumes of myoepithelial cells relative to (a) the total tissue volume and (b) to the acinar cell volume were calculated. The minor glands had a greater volume of myoepithelial cells (a = 3.06% +/- 1.79%; b = 4.61% +/- 3.13%) than the submandibular gland (a = 2.48% +/- 0.41%; b = 3.10% +/- 0.91%) or the parotid gland (a = 1.64% +/- 0.56%; b = 1.85% +/- 0.48%). Data analysed on a subject basis failed to reveal any significant difference in myoepithelial cell volume between glands. However, data analysed from individual electronmicrographs showed highly significant differences and supported the hypothesis that the volume of myoepithelial cells may be related to the viscocity of the saliva produced by the different glands.
取自正常人类腮腺、颌下腺及小唾液腺的标本用于电镜检查。通过先前报道的超微结构特征很容易识别出肌上皮细胞。对电子显微镜照片进行体视学分析，并计算肌上皮细胞相对于（a）总组织体积和（b）腺泡细胞体积的体积百分比。小唾液腺的肌上皮细胞体积（a = 3.06% ± 1.79%；b = 4.61% ± 3.13%）大于颌下腺（a = 2.48% ± 0.41%；b = 3.10% ± 0.91%）或腮腺（a = 1.64% ± 0.56%；b = 1.85% ± 0.48%）。基于个体分析的数据未显示各腺体之间肌上皮细胞体积有任何显著差异。然而，对单个电子显微镜照片分析的数据显示出高度显著的差异，并支持了肌上皮细胞体积可能与不同腺体产生的唾液粘度相关的假设。
