Fig. 4From: Protective effects of molecular hydrogen on steroid-induced osteonecrosis in rabbits via reducing oxidative stress and apoptosisTUNEL apoptosis detection. a The model group showed many apoptotic osteoblasts and osteocytes. b In the hydrogen group, few TUNEL-positive osteoblasts and osteocytes were found. c The apoptotic rate in the hydrogen group was significantly lower than that of the model group (P < 0.01)Back to article page
