Various cytokines (TNF-alpha, IL's,GSF etc.) and other factors play important preventing roles and are secreted during the infection. It may cause changes in the metabolism of neutrophils. Production of superoxide anion and antioxidative enzymes activities, such as glutathione reductase (GSSGR) and catalase (CAT) may be changed during MTB infection in the host. In this study, the control group consisted of ten healthy subjects and ten patients with TB, were studied before anti-TB treatment. Level of superoxide anion production, activity of CAT and activity of GSSGR were studied from peripheral neutrophils of healthy subjects and patients with TB. Catalase activities of the neutrophils were significantly lower in patients with TB than normal subjects (p< 0.01). Glutathione reductase activities of the neutrophils were also significantly lower in patients with TB than normal subjects (p< 0.05). Superoxide anion production in the neutrophils did not show any significant difference between TB and normal subjects (p> 0.05). As a result, the activities of CAT and GSSGR were lower in the peripheral neutrophils of patients with TB than normal subjects, whereas superoxide anion production in the neutrophils did not differ between in TB patients than normal subjects.eninfo:eu-repo/semantics/closedAccessneutrophilssuperoxide anioncatalaseglutathione reductasemycobacterium tuberculosisArticle263289298129014262-s2.0-0141939525Q3WOS:000184437500009Q4
