[Study of the zinc content of hair and serum in selected skin diseases].

The authors examined 2 groups of patients treated in the Department of Dermatology in Lublin: I--acne phlegmonosa patients, II--alopecia areata patients. In the I group the zinc content was examined in hair using the atomic absorption spectrophotometry method (ASA). The results obtained with this method were analysed in comparison with the zinc content in serum measured indirectly by the alkaline phosphatase activity. In the II group the zinc levels were determined in serum using the atomic absorption spectrophotometry method and next the results were compared with the alkaline phosphatase activities in serum in these patients. The correlation was stated between both the zinc level in hair, in serum and the alkaline phosphatase activity in serum.
