Fig. 3From: Protective effects of molecular hydrogen on steroid-induced osteonecrosis in rabbits via reducing oxidative stress and apoptosisOxidative stress and vascular injury in the proximal femurs. a The model group showed clusters of 8-OHdG-positive haematopoietic cells in marrow. b In the hydrogen group, sporadic 8-OHdG-positive haematopoietic cells were found. c The hydrogen group exhibited a lower 8-OHdG %PA than the model group (P < 0.01). d Strong immunoreactivity for MDA was found in marrow vessels and haematopoietic cells of the model group. e The hydrogen group exhibited weak immunoreactivity for MDA in marrow vessels and haematopoietic cells. f A smaller number of MDA positive vessels was found in the hydrogen group than the model group (P < 0.01). g Stronger ink leakage was observed in the model group. h The hydrogen group showed less ink leakageBack to article page
