ABSTRACT
Radad K, Marwah A, Sary KA, Youssef MS., Pathology in goats associated
with super-phosphate emissions, Onl J Vet Res., 11 (1) : 10-19, 2007. Patho-morphological changes in goats located
near the production of phosphate fertilizer were evaluated. Cadmium in blood, liver,
kidneys, lungs and heart of exposed goats increased compared with animals not
exposed to emissions. Hepatic tissue revealed vacuolar and fatty degeneration
with fibrosis whereas renal tissue showed glomerular swelling and periglomerular fibrosis, necrobiotic
changes of the tubular epithelial cells and increased fibroblastic and
lymphocytic activation in the interstitium. Pulmonary
lesions included alveolar emphysema, thickening of alveolar septa and
interstitial pneumonia. The heart revealed myocardial necrosis and fibrosis. In
brain tissue there was neuronal degeneration and activation of glial cells.
These changes were attributed to vascular damage associated with high levels of
blood cadmium due to superphosphate exposure.
