摘要
为了更详细准确地掌握人和实验动物涎腺在正常组织结构上的差异，使在选择动物模型进行涎腺研究时更具科学性，我们首次采用图象分析仪，系统地检测比较了８ 种实验动物和人正常涎腺腺泡的大小和腺体内各组织成分的平均体积比。结果发现：人和猴的３ 种腺体的腺泡大小无明显差异；除兔以外，人的腮腺腺泡最小；人的颌下腺腺泡大于啮齿类动物的颌下腺腺泡而小于其它动物的；除兔的舌下腺腺泡明显较小，羊的舌下腺腺泡明显较大外，其它动物与人无明显差异。粘液腺泡大于浆液和浆粘液腺泡。人体腮腺中腺泡明显少于其它动物，而间质较多；啮齿类动物颌下腺中导管系统的平均体积比远高于其它动物；舌下腺中，啮齿类动物的腺泡较多而间质较少，别的动物各组织成分差别不大。
The pairs of three major salivary glands of eight kinds of full grown experimental animals were sectioned and examined by morphometric techniques. The televised image analysis system was used to determine the acinar area and proportional volumes of component tissue. The results were compared with those of the same glands from human. There were no differences between the three acinar areas of human and monkey. The acinar area of human parotid was the smallest except that of rabbit. The acinar area of human submandibular gland was larger than that of rodents but smaller than that of other animals. There were no differences between the acinar area of sublingual glands of human and amimals except those of rabbit and goat. The acinar area of mucous acini was larger than that of serous and seromucous acini. The mean proportional volume of acini of human parotid was less than that of other animals. The duct systems of rodents submandibular were far more than those of other animals. In sublingual glands, there were no differences in mean proportional volume of component tissue between human and animals except there were more acini and less fiber in rodents' subingual glands.
