Hair-zinc levels determination in Algerian psoriatics using Instrumental Neutron Activation Analysis (INAA)

摘要

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 + 53ug/g and 167 + 52ug/g respectively. They are not significantly different (p>0.05). Zn concentration for males and females controls and patients were 171+27ug/g, 151+37ug/g and 145 + 59ug/g, 178 + 58 ug/g respectively. However, for females we have observed a significant difference (p < 0.05).
