味覚の臨床的研究 第2編 血液含有物質，胃液酸度及び唾液pHと味覚との関係に就て

The corrlation among the cotained substance in blood, the acidity of fastric fluid the pH of saliva and the taste was observe on the attacked paiod and convalescen pariod of disease. And the resulte were as follows. 1. Observing on the correlation between the dosis of serum sodium and the throshold value of taste, the threshold value of sweed taste showed the high value in many cases with the low value of serum sodium at the attacked period of disease and it showed the declining tendency with the increase of serum sodium by the recovery of disease. No fixed correlation between the dosis of serum sodium a d the salt, sour or bitter taste was observed. 2. The correlation between the dosis of serum chloride and the threshold value of saste was similar to that on the occasion of serum sodium. 3. As for the correlation between the dosis of serum potassium and the threshold value of taste, many cases with the high value of serum potassium at the attacked period of disease showed the high value of serum potassium at the attacked period of disease showed the high threshold value of sweet and bitter taste and they showed the returning tendency to normal value at the convalescent perio with normal value of serum potassioum. No fixed correlation between the dosis of serum potassium and the threshold value of salt or sour taste was observed. 4. As for the correlation bet ween the dosis of serum iron and the threshold value of taste, the threshold value of bitter taste showed the tendency taking the high value on the low value of serum iron. The tendency was especially remerkable in the patients with anemia. No fixed relation between the dosis of serum iron and the threshold value of sweet, salt or sour taste was not observed. 5. As for the correlation between the dosis of serum copper and the threshold value of taste, the theshold value of sweet and sour taste showed the tendency to declins, as the dosis of serum copper became decreased at the attaked period of disease in many cases. And they showed the tendency to decline with the decrease of serum copper at the convalescent period, but no fixed correlation between the desis of rerum copper and the threshold value of salt or bitter taste. 6. The correlation between the increase or decrease of blood sugar at the hunger time and the rise of decline of the threshold value of sweet or sour taste was observed on various diseases, other than diabetes, In diabetes, the threshold value of sweet taste at the hunger time showeed the high valun, but no fixed correlation between the blood sugar at the hunger time and the threshold value of salt or bitter taste was observed. 7. No fixed correlation among the dosis of serum protein, the acidity of gastric fluid, the pH of saliva the threshold value of taste was observed.
