The effects of Naringin on neuroprotection. a Represents photomicrographs of Nissl staining of brain tissue sections across hippocampus CA1 region (magnification 400×). b Represents photomicrographs of TUNEL staining of brain tissue sections across hippocampus CA1 region,TUNEL staining to detect neuronal apoptosis in the brain tissues of rats, arrows indicate apoptotic cells (magnification 400×). c The TUNEL-positive cells. Values are expressed as mean ± SEM, n = 3 (^#P < 0.05, ^##P < 0.01 vs sham, ^*P < 0.05, ^**P < 0.01 vs CCL2)
