摘要
A gross pathology and histological investigation was carried out on bovine target organs of anabolic substances in the Molise Region (Italy). One hundred forty-four bovines (12-24 months old, 123 males and 21 females) were included in the survey. An antemortem assessment of their behavior and clinical examination were performed. After slaughter, samples of prostate. Cowper%26apos;s glands, Bartholin%26apos;s glands, mammary gland, ovaries, thymus and thyroid were collected, inspected and processed for histopathology, as suggested in the guidelines of the Italian national program for residue surveillance (PNR). Overall, 15.3% of the examined animals were classified as %26quot;suspect,%26quot; 44.4% were classified as %26quot;uncertain,%26quot; and the remaining 40.3% were classified as %26quot;negative.%26quot; The most frequent lesion was a severe thymus atrophy with fat infiltration (15.4% of males and 14.3% of females), strongly suggesting the illegal use of corticosteroids.
