Alterations along the Hypothalamic-Pituitary-Thyroid Axis of the Zebrafish (<i>Danio rerio</i>) after Exposure to Propylthiouracil

<table>Representative macroscopical pictures of the head region of zebrafish (<i>Danio rerio</i>) following exposure to 0, 10, 25, and 50 mg/L PTU. Increased red coloration due to blood aggregation in the opercular region (*) at concentrations ≥10 mg/L and goiter formation (△) at concentrations ≥25 mg/L are clearly detectable.</table>
