Levels of hydroxyproline, SOD and MDA in wound tissues

Groups	Ctrl	DM-Ctrl	DM-SN	DM-PB
Hydroxyproline (μg/mg)	0.0073 ± 0.0013	0.0186 ± 0.0017	0.0087 ± 0.0013	0.0092 ± 0.0016*†
SOD (U/mL)	3.12 ± 0.12	2.15 ± 0.48	4.57 ± 0.36∗	6.82 ± 0.75*†
MDA (nmol/mg)	0.08 ± 0.67	0.17 ± 0.58	0.15 ± 0.79	0.11 ± 0.63*†

Each value was expressed as mean ± SEM (n = 6). ^∗P < 0.05, DM-PB group versus DM-Ctrl group; †P > 0.01, DM-PB group versus DM-SN group. SOD: superoxide dismutase activity; MDA: Malondialdehyde activity.
