Exposure to MeHg caused a reduction in the immunomarked area in myelin basic protein in all areas evaluated. Effect of MeHg on the cervical (A–C), thoracic (D–F) and lumbar (G–I) segments of the spinal cord in the offspring rats (n = 7 animals per group) after exposure during the intrauterine and lactation period to 40 μg/kg/day of MeHg (samples collected 21 days after 42 days of dosing). (A,D,G) are representative photomicrographs of the assessment of the fraction of area immunolabeled by anti-myelin basic protein (MBP) in the control group and (B,E,H) in the exposed group. Counterstaining with Harris hematoxylin. In (C,F,I) are the results of the MBP area fraction, expressed as the mean and interquartile deviation (n = 7–8 animals per group). * p < 0.05, Mann–Whitney test. Scale bar: 20 μm.
