Figure 4. Sevoflurane postconditioning reduced neuropathic damage after cerebral I/R injury. (A) Representative photomicrographs of Nissl staining in the hippocampal CA1 region (scale bar = 50 μm and 1000 μm respectively). The arrow points to shrunk and degenerated cells in CA1 region. (B) Representative images of histopathological changes in the hippocampal CA1 of rats (scale bar = 50 μm and 1000 μm respectively). The arrow points to shrunk and degenerated cells in CA1 region. (C) Quantification of numbers of Nissl bodies in the hippocampal CA1 region. Data are expressed as mean ± SD (n = 5 per group).
