[Zinc and its status in some dermatologic diseases--a statistical assessment]

This report contains statistical interpretations of blood- and serum-levels of zinc, magnesium and copper, including dates of 380 patients with alopecia areata, alopecia androgenetica, psoriasis vulgaris, vitiligo, rosacea, venous ulcer and atopic eczema, compared with 31 healthy people. Significant low blood-levels of zinc were only proved in vitiligo, significant high levels were found in all patients of the psoriasis group. The serum-level of zinc was low in diagnoses as well as the blood-levels of copper. Blood- and serum-levels of magnesium were similar in all dermatological diseases; all of them were increased in comparison with the control group (significance level p = 0.05). Furthermore there were linear dependences of the variables, due to the examined diseases. It is of some interest that we could not prove a normal distribution of blood- and serum-levels of magnesium as often described in literature.
