Aim: The aim of the
present study was to examine the histopathological alterations caused by
acrolein, an aquatic herbicide, in the gill and kidney tissues of Carassius
fish were exposed to sublethal concentrations of acrolein (1, 5 and 25 µg l-1)
for 96 hr. The gill and kidney tissues were removed, fixed and embedded in
paraffin. Histological sections of the treated tissues were investigated by
light microscopy and compared with the control group.
exposure caused hyperplasia, aneurism, edema, curling and shortened secondary
lamellae, epithelial lifting, desquamation, hypertrophied mitochondria-rich
cells, dilated central vein, separation of primary lamella epithelium from
the cartilaginous tissue and necrosis in the gills. The kidney tissues showed
vasodilatation, congestion, enlarged melanomacrophage centers, vacuolization
in the renal parenchyma, separation of tubules and collecting ducts from the
parenchyma, hyperplasia, vacuolization and deformation in the tubule
epithelium, fibrous tissue configuration in the parenchyma and around the
collecting duct, hemorrhage, infiltration and necrosis.
exposure caused damaging effects on the gill and kidney of goldfish.
Alterations in the vital organs probably would affect the metabolic
activities and even the survival rate. From the environmental and health
protection point, acrolein has to be taken into consideration.
