The transversely cut segments from the middle parts of the tongues were embedded in paraffin. Histologic sections of 5μm thickness were prepared. Lingual tissue were examined histologically. Specimens were stained by hematoxylin-eosin, elastica van Gieson, and Azan-Mallory stainings. The stenotic index of human lingual arteries (area of lumen / area of intima and lumen of lingual artery × 100) (S.I) was calculated on the elastica van Gieson-stained slides by using an image analyzer system (Pias, LA555N). The results were as follows: 1. The lingual arteries, showed rupture and multilamellation of lamina elastica interna, as well as proliferation of intimal elastic fiber in almost all cases. 2. A decrease in the S.I was indicated in the lingual arteries with the progress of aging. 3. Calcification was observed at the intima and media of lingual arteries in a small number of cases (5 cases). These findings indicated that histological changes due to arteriosclerosis of lingual arteries was intimal thickening and lipid deposion; atherosclerotic changes was not observed.}, pages = {99--105}, title = {<原著>ヒト舌の加齢的変化 : 組織計測学的研究 : 第1報 舌動脈の狭窄度について}, volume = {9}, year = {1990} }
