Fig. 4From: Tanshinone I alleviates motor and cognitive impairments via suppressing oxidative stress in the neonatal rats after hypoxic-ischemic brain damagePretreatment of TsI rescues the decrease of NeuN-immunoreactive neurons in the hippocampal CA1 region of neonatal HIBD rats. a Representative photomicrographs of different treatment. Scale bar = 400 μm for left panel and 50 μm for right panel. b Bar graph summarizing the relative number of NeuN-immunoreactive neurons in the CA1 region of hippocampus. Data was expressed as mean ± SEM. **p < 0.01Back to article page
