BSA-SeNPs shield the hippocampus from neuronal injury and cognitive decline in the subacute phase of h-ICH. (A) Illustrations of the experimental grouping and the treatment procedures. (B–D) Schematic diagram of the testing procedure (B), the exploration time (C), and the discrimination index (D) in the object recognition task (n = 4). (E) Hemorrhagic volume (F) Representative images of HE staining in the hippocampus (n = 4, scale bar: 200 μm, 20 μm). (G–J) Images of Nissl staining (n = 4) of treated hippocampus (DG, CA1, and CA3 fields, scale bar: 20 μm), DG: dentate gyrus. *P < 0.05, vs Control; ^#P < 0.05, vs h-ICH; ns, no significance.
