Description In order to assess the effects of lead (Pb) on gill and kidney of an estuarine
fish, Liza parsia the fish was exposed to sublethal concentration (0.5 ppm)
of lead nitrate in sea water for 15 days. Gill responded initially with an
enhanced secretion of mucus and oedematous separation of the epithelial
lining cells from the basement membrane of the secondary gill lamellae.
Hyperplasia, multiple telangiectases (aneurysms), desquamation of the
epithelial cells, complete fusion of secondary gill lamellae and congestion of
blood sinuses were the significant histopathological lesions observed in the gill
during the period of observation. The entire interlamellar spaces became filled
with the hyperplastic epithelium by day 15 of Pb exposure. Trunk kidney of
the treated fish revealed initial hypertrophy and vacuolation of the epithelial
cells lining, proximal convoluted tubules and shrinkage in the glomeruli
resulting in dilation of Bowman's space on day 4. Necrotic changes like
oedema, pycnosis, karyorrhexis, karyolysis, cytolysis and fibrosis were
observed in the kidney of the fish exposed to Pb intoxication.
