[Relationship between female ages and the theory of five tones correlated with five zang viscera in Huangdi Neijing].
OBJECTIVE
To find out some evidence that may indicate the theory of voice pitch of the five tones being correlated with the five zang viscera in Huangdi Neijing, which was lost 2 000 years.


METHODS
Eight-four healthy females were divided into younger group (<34 years old) and older group (> or =34 years old) according to their ages. The pronunciations of these females were examined by sono-frequency analysis facility.


RESULTS
The frequency of Jiao tone was much higher than those of the other tones in both groups (P<0.01) and the frequency of Jiao tone increased as aging. The frequency of Zhi tone in the younger group was higher than that in the older group (P<0.05).


CONCLUSIONS
The results of higher frequency of Jiao tone in females is in accordance with the theory put forward by Ye Gui (a famous doctor in Qing Dynasty of China) that the liver is the congenital base of female life. In traditional Chinese medicine, Jiao tone is correlated with the liver, and Zhi tone is correlated with the heart. The high frequency of Zhi tone in younger females implies that regulating the Small Intestine Meridian of Hand-Taiyang and Heart Meridian of Hand-Shaoyin may be beneficial to the health maintenance of younger female.
