ABSTRACT
Radad K, Marwah A, Sary KA, Youssef MS., Effect of cadmium emissions on hematology and
tissues in goats, Onl J Vet Res., 28(5): 303-309, 2024. Manufacturing
of phosphate fertilizers is
associated with the release of cadmium. Tissue and blood samples were taken from 70
adult male goats reared beside a superphosphate factory in Upper Egypt whereas
controls were ~10 kilometers further.
Blood and liver, kidneys, lungs, heart and brain were excised from all
goats for cadmium levels. Compared with controls blood cadmium was 49, liver 58,
kidney 59, lung 43 and heart 67% higher (P < 0.05 -0.001) in goats exposed
to emissions. Microscopy revealed
vacuolar, fatty degeneration and fibrosis in liver whereas in kidneys we found
glomerular swelling and peri-glomerular fibrosis,
necrosis of renal tubular epithelial cells, fibrosis and lymphocytic
infiltrations. In lungs we observed alveolar emphysema, thickening of alveolar
septa and interstitial pneumonia whereas in heart tissue we found myocardial
necrosis and fibrosis. In brain neuronal degeneration and activation of glial
cells occurred. Findings suggest vascular damage due to cadmium induced microscopical changes in tissues.
