人与牛犬主泪腺腺泡的组织学比较

COMPARISION OF MAIN LACRIMAL GLANDS OF MAN,BULL AND DOG

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。

The main lacrimal glands of man,bull and dog were studied with histological, histochemical and electromicroscopic methods.The results showed that although their lacrimal glands decribed as mucoserous glands,differences in shape,number,histochemical reaction and ultrastructure were obvious,heterochromatin was also different in distribution.The nuclei of acinar cells had different shapes.The results suggest that there are obvious species differences in main lacrimal glands.
