“…Deficiency of zinc causes growth retardation, defective collagen synthesis, skeletal abnormalities, poor wound healing, impaired immune function, night blindness, sickle cell anemia and impaired protein synthesis (Gropper & Smith, ). Previous studies showed either lower (Arıca, Arıca, Özer, & Çevik, ; Keikhaei, Badavi, Pedram, Zandian, & Fakher Rahim, ; Mahyar et al, ) or higher concentrations of Zn in patients (Mehdizadeh, Zamani, & Tabatabaee, ), and also showed correlation with Cu (Bashir, ; Fukushima et al, ; Mahyar et al, ; Naji, ), which is an important constituent of hemoglobin. In this study, Cu levels were found to be higher in patients as compared with controls.…”
