ABSTRACT
Radad K*, Marwah A, Sary KA, Youssef MS Pathology in goats associated with super-phosphate
emissions, Online 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.
