家畜哈德氏腺及瞬膜腺的形态学观察

对马、驴、牛、奶山羊和猪的哈德氏腺及瞬膜腺进行解剖及组织学观察,表明这些家畜的瞬膜及瞬膜腺都很发达,在腺体的间质内都查到一定量的淋巴细胞和浆细胞,而位于瞬膜深部的哈德氏腺只有猪是一个发达而又独立的腺体。牛的哈德氏腺不发达,紧连在瞬膜腺之尾部,并与瞬膜腺包于同一被膜,两者无明显的界线。在显微镜下可观察到这两个腺体的区别,但未观察到马、驴、奶山羊的哈德氏腺。

AN OBSERVA TION OF HARDERIAN AND NICTITATING GLANDS IN DOMESTIC ANIMALS

The Harderian and nictitating glands in horse,donkey,cattle,dairy goat and swine were observed anatomically and histologically.The results showed that the nictitating membrane and the nictitating glands were both well-developed.A certain number of lymphocytes and plasma cells were found in the interstitial substance of the glands.The Harderian glands were situated in the deep part of nictitating membrane only in swine,which were well-developed and separated from other tissues.The Harderiatnglandsincattlewere poorly-developed and just closely linked o the tail of the nictitating glands and enclosed in the same connective tissue capsule. There was no apparent demarcation between Harderian and nictitating glands,but the difference between these two glands could be seen under the microscope. Harderian glands were not seen in horse,donkey and dairy goat.
