| Summary: | The purpose of this work was to describe the histopathological effects of chronic
cadmium intoxication on liver, gill, kidney, intestine and striated muscle in silver
crucian carp Carassius auratus gibelio. 25 immature 1+-year-old crucian carp were
obtained from a private fishfarm and acclimated to laboratory conditions. After a 21
days exposure to a sublethal cadmium concentration (1.625 ppm from a Cd
(CH3COO)2 x2H2O stock solution), liver, gill, kidney, small intestine and striated
muscle were sampled and processed for histological examination.
Histopathological alterations induced by studied heavy metal in the tissues of silver
crucian carp specimenes were: nephrocite hypertrophic processes, distruction of
intercellular jonctions, stratification of epitelium and congestions both in renal
glomerulis and in interstitium; hyalinizations, congestions of blood vassels and
vacuolations associated with lipid accumulation at the hepatic level; into intestinal
mucosa revealed rich leucocyte infiltrates, with numerous leucocytes situated
intraepithelial; branchial lamelles with disordered aspect and multilayered
epithelium, vascular ectasias and leucocyte infiltrates into subepithelial connective
tissue at the gill level; miolisis processes in peripheral muscular fibers manifested by
contractile apparatus alteration on large areas. |
