Superficial tongue blood volume and the tongue spectrophotometric determination on coronary heart disease with blood stasis syndrome

The tongue bodies of coronary heart disease (CHD) patients with blood stasis syndrome were looking dull purple in different degree. The authors adopted two kinds of biophysics methods which are tongue spectrophotometer and DM-80-6 superficial tongue blood volume meter. 52 CHD patients with blood stasis syndrome, 50 normal individuals and 26 patients before and after the treatment according to promote blood circulation to remove the blood stasis, were examined. The results were as follows: The purple ray values of the tongue spectrum of the CHD patients with blood stasis syndrome were more than that of normal individuals. Statistics showed significant difference (P less than 0.01). So was the tongue blood volume (P less than 0.01). In the treatment group, the purple ray value of tongue spectrum reduced, and the red ray volume of tongue increased significantly, as well (P less than 0.01). The results suggested that both methods may be quantitative comparative parameters for diagnosis, differentiation of symptoms and signs, and evaluation of the therapeutic effectiveness.
