Abstract

Reactive oxygen species (ROS) are crucial in all wound-healing processes. Raftlin also plays an important role in the induction of the autoimmune response and the vascular inflammatory response. Inflammatory mediators induce continuous synthesis and secretion. To the best of our knowledge, although there are studies in the literature on antioxidant enzyme levels (superoxide dismutase [SOD], catalase [CAT]) and oxidative stress markers, there are no studies on the comparison of these levels in wound patients with the activities of Raftlin, which is known to play a role in the vascular endothelial response. The aim of this study was to compare the levels of oxidative stress and antioxidant response between wound patients and a control group and to compare the levels of Raftlin between the two groups, which is a new biomarker in inflammatory diseases. Between January 2018 and September 2018, 30 healthy control patients and 30 patients with wounds were enrolled in the study as volunteers. Tissue samples were collected and were sent to the biochemistry laboratory to determine the levels of oxidative stress, antioxidant enzymes, and Raftlin, which play an important role in wound healing. The following were evaluated: SOD and CAT levels (as a measure of antioxidant enzymes); malondialdehyde (MDA) levels (as a measure of free oxygen radicals); and Raftlin, which is a lipid raft protein used in determining the level of inflammatory and autoimmune response. The analyses determined a statistically significant correlation between MDA, SOD, CAT, and Raftlin values in wound patients (p<0.05). Raftlin was a considerable parameter in determining the prognostic process of wound healing. The levels of tissue Raftlin were significantly higher in wounded patients. A significant increase in MDA, SOD, and CAT activities of the wounded patients also suggested that the oxidant and antioxidant effect was balanced and that external antioxidant supplementation was not required.
