CUTANEOUS SODIUM AND POTASSIUM DETERMINED BY REVERSE IONTOPHORESIS

[摘要] In several dermatoses reverse iontophoresis removed concentrations of Na and K from the uninvolved skin indicating it is altered and only apparently normal. If further experience confirms these preliminary results some of these changes may help explain some clinical facts, such as the tendency to form ids in some cases of stasis eczema and ulcers, the tendency of dermatitis venenata to spread to distant sites, some characteristics of the skin in pemphigus such as acting as a reservoir for water and Na, and the waterlogging of the skin in atopic eczema. These results are obviously preliminary and based on an insufficient number of cases. They suggest fundamental alterations, but need much more work to corroborate them.
