Abstract

The nail has been considered to be the best human model to evaluate the general body state at all ages. The present study was disigned to measure the nail growth rate and to define the correlation of them with other values of nail size. The subjects were 373 males and 812 females whose ages from R months to 79 years. The results were as follows: 1. The linear elongation of the nails were most rapid in the 14 to 15 year-old age group. It decreased steadily as the subjects got older and olr1er. 2. Sex differences in the nail growth rate were not statistically significant. R. Where were no statistically significant differences in the linear growth rate of nails between right and left hands. 4. The middle finger nail grew more quickly than others, while the thumb and little finger nails grew more slowly. 5. Linear growth of nails were not significantly correlated to the thickness and length of nails and the length of lunulae.
