The lymphatic vessels and regional nodes of the nasopharynx in 70 foetuses and infant cadavers were studied with the method of injection of the lymphatics of the organ.There is a network of lymphatic capillaries in the mucous membrane of the nasopharynx, which drains into the submucous lymphatics. The latter join together to form a number of efferent ducts.The efferents emerging from the posterior wall of the nasopharynx end in the retropharyngeal lateral and medial nodes, or pass to the posterior aspect of the internal carotid artery and internal jugular vein and end in the upper deep cervical nodes lying deep to the tip of the mastoid.The lymphatics emerging from the lateral wall drain into the nodes right under the base of the skull anterior to the internal carotid artery and internal jugular vein, or descend to the jugulodigastric node, and the upper deep cervical nodes between the beginning point of the lingual artery and the bifurcate point of the common carotid artery.

Seventy two diabetic subjects type Ⅱ were given konjac food for 65 days.The data analysed by multiple F-test indicated that the fasting blood glucosc(FBG), 2-h postprandial blood glucose (PBG) at the 30th and 65th day after consuming the food were significantly reduced (P = 0.001, P200mg%) decreased on the average by 51.8 and 84.6 mg% respectively, those with FBG-O 150-200 mg% by 24.1 and 68.7mg%, and those with FBG-0200 mg%).It could be concluded that konjac food was very useful in both prevention and treatment of hyperglycemia.
