采用组织学、组织化学及透射电镜的方法对人、牛、犬的主泪腺腺细胞进行了比较形态学研究。结果表明人、牛、犬的主泪腺腺细胞均为浆粘液性,但其组织化学及超微结构均有明显的差异,各自腺细胞分泌颗粒的大小、数量、结构及 PAS 反应的强度、细胞核的形态及异染色质的分布等均不同。上述各种动物的泪腺结构及组织化学的种属差异,说明其泪腺的功能活动规律及生物作用等有种属特点。
Histology, histochemistry and transmission electron microscopy of human, bovine and canine lacrimal gland cells were compared morphology. The results showed that the main lacrimal gland cells of human, cow and dog were all mucoid, but histochemistry and ultrastructure were different. The size, number, structure and the intensity of PAS reaction, the morphology of nucleus And heterochromatin distribution are different. The lacrimal gland structure and histochemical species of the above-mentioned various animals, indicating that the lacrimal gland function of the law of movement and biological characteristics of species.
