Fig. 11From: Preliminary Studies on Biodegradable Zinc Oxide Nanoparticles Doped with Fe as a Potential Form of Iron Delivery to the Living OrganismIron content in the brain calculated with Perl’s staining and MicroImage software. Results calculated as a ratio of area and intensity of iron-positive stains to the area of cell nuclei. Data presented as mean (±SEM) result for each, examined animal (a) and as mean (±SEM) value for both control and experimental groups (b)Back to article page
