Protective effects of M. nigra against d-galactose induced cell loss in the hippocampus of mice revealed by hematoxylin and eosin (H&E, ×100) staining. (A) Control group: the neurons are full and arranged tightly, the nuclei are light stained; (B) d-galactose group: focal disappearance of neurons and red neurons, as the arrows pointed neurodegeneration was evident (neurons are shrunken, the nuclei are side moved and dark stained); (C) d-galactose + M. nigra 50 group: one red neuron observed; neurodegeneration reduced as the arrow marked; (D) d-galactose + M. nigra 100 group: one red neuron observed the neurons normalize, the nuclei are light stained and arranged tightly and neurodegeneration was attenuated significantly.
