Prophylactic Zinc and Therapeutic Selenium Administration Increases the Antioxidant Enzyme Activity in the Rat Temporoparietal Cortex and Improves Memory after a Transient Hypoxia-Ischemia

Figure 7

The administration of the combined treatment with zinc and selenium decreases the number of pyknotic cells in the temporoparietal cortex of hypoxia-ischemic rats. Representative micrographs with hematoxylin-eosin staining. The headings indicate the different experimental conditions. (g) Counting of pyknotic cells in the control groups treated with zinc or zinc + Se. (h) Counting of pyknotic cells in the groups with CCAO and treated with zinc (zinc) or the combined treatment with zinc (zinc + CCAO) and selenium (zinc + CCAO + Se). Each value represents of 5 independent experiments made in triplicate. , one-way ANOVA with post hoc Dunnett’s test when compared with the untreated control group; , Student’s -test when compared with the CCAO group.
