An analysis of blood cell pouring on the tongue surface in 3032 healthy persons

: This paper deals with the utilizing laser frequency multiplexing technique and Doppler effect, successfully to build up LDB-1 type of laser microcirculation blood flow meter. It was used to carry on a determination for blood cell pouring amount on tongue surface in 3032 healthy persons. The results were shown as follows. The average tongue blood cell pouring amount of healthy persons was 4.74 +/- 0.50, in which the male was 4.82 +/- 0.50, and the female was 4.66 +/- 0.49. Apparently, there was a great difference between them (P less than 0.01). Following the increase of age, the tongue blood cell pouring amount was gradually decreased. The average blood cell pouring amount of a group of 1-9 years old was 6.14 +/- 0.79, of over 60 years old was 3.89 +/- 0.39 (P less than 0.01). In the light red tongue, the average tongue blood cell pouring amount was 4.95 +/- 0.93, which was considered to be the highest; in the purple tongue, it was 3.96 +/- 0.44 which was considered the lowest. The average pouring amount in the red tongue was 4.94 +/- 0.77, and in the light white tongue was 4.21 +/- 0.52. The more red the tongue showed, the greater the tongue blood cell pouring amount would be; whereas, the more purple the tongue showed, the lower the tongue blood cell pouring amount would be. It obviously indicated that the tongue blood cell pouring amount would be. It obviously indicated that the tongue blood cell pouring amount could correctly reflect the different tongue characters and tongue blood circulation condition.
