Abstract
Psoriasis is a multifactorial skin disease with an unknown etiology. Zinc has a positive impact on psoriasis. The aim of this study is to determine hair-zinc concentration in Algerian psoriatics. 58 psoriatics and 31 normal controls of both genders were selected. Hair zinc levels were determined using Instrumental Neutron Activation Analysis technique (INAA). Student's t-test and One-Way ANOVA were applied. The average zinc concentration for controls and patients were 152±53μg/g and 167±52μg/g respectively. They are not significantly different (p>0.05). Zn concentration for males and females controls and patients were 171±27μg/g, 151±37μg/g and 145±59μg/g, 178±58μg/g respectively. However, for females we have observed a significant difference (p<0.05).
