RESUMEN
Measuring the length of the proportional units of the lower limb and analyzing their interrelations showed that between genders there were significant differences in a length of one can of perpendicular proportional unit for various regions of the lower limb; within the same gender, there were different results in comparing the lengths of one of perpendicular proportional unit among various regions of the lower limb.
RESUMEN
Fifty-one fresh adult cadavers (male 21, female 30) were randomly selected. The required acupoints were localized and then the cadavers were frozen for anatomical dissection. Distance between the shallow point on the skin and the dangerous zones were measured after the cavaders were unfrozen. Data were analyzed statistically. The results showed that safe needling depths for Fengfu, Yamen, Fengchi and Jingming were 40.08mm, 38.10mm, 39.70mm and 34.25mm, respectively
