Abstract
In the previous report, the author obtained the values of mineral losses through the skin in the summer period, and in this experiment, those of spring period were determined to compare the previous report.
The condition of the sweat collection is exactly same with that of the previous experiment.
The subjects were three healthy women, 21-23 years old.
The sweat was collected over 6 days.
The amounts of daily loss through the skin were as follows: copper was 0.7mg or more, iron 2.0mg. or more, calcium 34mg. or more and phosphorus was 42mg. or more respectively.
Comparing these data with the previous summer period ones, the ratios of summer to spring were as follows: copper was 1/2, iron was 1/4, and those of calcium and phosphorus were almost 1. It was seen that the greater paret of iron loss from the skin was consisted of strip of the skin.
Same as previous experiment, it was recognized again that the skin was a main excreting route of copper and iron in human body.
