颌下腺器官内淋巴管的观察

Observation on intraorgan lymphatics of submandibular gland in fetus and dog

本实验采用墨汁硝酸银水溶液局部动脉注入方法和色素间接注入方法,对80例胎儿、10例犬的颌下腺器官内淋巴管的分布进行了观察,所见结果表明:在颌下腺小叶内不存在淋巴和毛细淋巴管,但可见大量的毛细血管,并在腺泡周围吻合成网;颌下腺器官内淋巴管是以盲端起始于小叶门附近;淋巴管和毛细淋巴管只存在颌下腺小叶间结缔组织内和被膜内。

The 80 cases and 10 cases of submandibular gland from human fetus and dogs were respectively studied. The serial sections were made for the specimens, after direct injection of Chinese Ink and silver nitrate into local artery and indirect injection of the coloured ceder oil. The results are as follows. There are no lymphatic capillaries and vessels in the lobules of the submandibular gland, but there are many blood capillaries. lymphatic capillaries and vessels only appear among lobules and in the capsule of the gland. The lymphatic capillaries begin with blind capsule near the hilus of the lobules. The lymphatic vessels go mainly with artery.
