Title StatementImpact of acute copper intoxication of some organs of clarias macrocephalus gunther by Annabelle A. Herrera and Cymbeline Perez
Physical Description195-207 figures, illustrations, photos
Summary, Etc.Effects of acute copper exposure to Clarias macrocephalus at 1.2 mgl-L were determined over a period of 48 hours. The gill filaments, kidney and liver were eXf,lmined for any pathological effects. Histological analysis showed extensive changes in each organ. The gill filaments exhibited hyperplasia of lamellar epithelium, cell proliferation between secondary lamellae and a corresponding reduction of the interlamellar space. Increased. vacuolation, widespread necrosis and degeneration of epithelial cells were likewise evident. The tail kidney was characterized by irregularly-shaped cells. Dilation of the Bowman's space with accompanying hypertrophy of the glomerulus was evident. Extrusion of cellularmaterials characterized the lumen of the tubules. The liver tissue snowed general destruction. It was marked by the absence of sinusoids, increased vacuolation and the presence of partially coagulated blood in the central vein
