Correlative Analysis on Tongue Manifestation and Symptoms of Acute Respiratory lnfection Diseases

This investigation analyzed the thickness and color of tongue fur and the pH and degree of dryness and wetness of the lingual surface in 61 patients with acute respiratory infections using correlation coefficient analysis.In this study,thickening of the tongue fur was observed in 97%, abnormal accumulated points of tongue fur color in 98%, acidity of the lingual surface pH in 70%, and an abnormal degree of dryness and wetness of the lingual surface in 46%.Correlation coefficient analysis gave a correlation of at least 0 32 for each of the above mentioned indices.The correlation between changes in tongue manifestations and symptoms,and between different symptoms showed that the two of four symptoms investigated are important elements of internal asthenia and the heat syndrome of TCM.Correlation coefficient analysis also showed a correlation between tongue manifestations and internal heat symptoms.We think research into the correlation between different tongue manifestations and between tongue manifestations and symptoms forms the basis of investigations into the mechanism of the formation of different tongue manifestations and syndrome differentiation theory.
