Fig. 4From: Topical rhubarb charcoal-crosslinked chitosan/silk fibroin sponge scaffold for the repair of diabetic ulcers improves hepatic lipid deposition in db/db mice via the AMPK signalling pathwayEffect of RCS/SF scaffold on ameliorating hepatic oxidative stress in db/db mice. A Hepatic SOD activity. B Hepatic CAT activity. C Hepatic NAD+/NADH activity. D Hepatic MDA contents. The values reported in the figure represent the means ± SEM (n = 5–6). ##P < 0.01, #P < 0.05 compared with the db/m group; *P < 0.05 compared with the RC groupBack to article page
