제목 Novel kraft lignin-gelatin hydrogel for suppressing over-expressed reactive oxygen species to treat diabetic ulcer
초록 Diabetic ulcer is one of the most common complications for patients with diabetes. It is difficult to treat since high blood sugar increases blood viscosity, which leads to insufficient nutrient supply towards nerves within the defect site. Specifically, over-expressed reactive oxygen species (ROS) accelerates advanced glycation end products (AGEs) by affecting glucose level, leading to blood supply disorders and chronic skin disease. In this study, a novel kraft lignin based antioxidant hydrogel was fabricated. Kraft lignin was introduced to gelatin matrix (Klig-Gel) and cross-linked via epoxidation. The chemical structure of kraft lignin chelates ferrous iron (Fe2+), which is the main factor that increases ROS expression though the Fenton reaction. Klig-Gel hydrogel was able relieve oxidative stress and inhibit over-oxidation process effectively. Therefore, it shows possibility to normalize the balance between natural antioxidant and ROS, and enhance diabetic ulcer treatment.
