味覚の臨床的研究 第1編 疾病に依る味覚閾値の変動

The threshold value of taste was measured in 144 cases on the admission and the convalescent period with treatment. And the result were as follows. 1. On the attac of disease, the rate showing the threshold value over normal was high in ordor of the sweet, bitter, sour and salty taste. 2. As for the rising degree of threshold value over normal limit, many cases showed the slight rise of sweet, salty and sour taste and there were considerably many cases with the high rise of bitter taste. 3. As for the change of the threshold value of taste before and after the treatment, the salty and sour taste changesd within normal limit in many cases, the sweet and bitter teste showed abnormal threshold value before the treatment in pretty many cases. But the cases showing abnormal threshold value of the above 4 tastes before the treatment showed the returning tendency to normal threshold value after the treatment. 4. The resing degree of the threshold value of taste was different with eaoh disase, the sweet saste showed the high rise in dncdenal ulcer and hapatitis and it showed the slight rise in chronic gastritis and anemia. The cases with the rise of salt taste were few and the degree of rise was also slight, but there were many cases with the rise of salt taste in nephritis and heart failure. And there were few cases with the rise of salt taste in fever disease, out there were many cases with the high rise in the above cases. The rising degree of sour taste was slight in many cases, but there were many cases with the rise of the threshold value in livercirrhosis and high fever. The bitter teste showed considerably high rise, especially it was remarkable in stomach ulcer, liver disease, heart failure, and high fever. But it died not show in most of chronic gastritis and diabetes. 5. There were many cases showing the high threshold value in the cases with thick fur and it was thought that the multiplication of tongue papilla influenced upon the sweet taste. The remarkable change of threshold value was not observed on the cases with papillar atrophy and tongue fissure. 6. No fixed correlation between the colloidal reaction of liver function in liver disease and the threshold value of taste was observed. 7. The rise of the threshold value of bitter taste was observed on many cases with the decline of glomerular filtrating dosis in kidney disease, but the relation to the salt taste and other taste was not observed.
