Description Gill of Liza parsia exposed to sublethal concentration (0.5 ppm) of BHC
responded initially with the copious secretion of mucus followed by
oedematous separation of epithelial lining cells from the basement membrane.
Fusion of secondary gill lamellae, tissue hyperplasia and multiple telangiectases
(aneurysms) were noticed on day 10 of the exposure. By day 15, the entire
interlamellar spaces became filled with the hyperplastic epithelium. Kidney
revealed an initial hypertrophy of the cells lining proximal convoluted tubules
followed by shrinkage in the glomerular tufts resulting in the increase of
Bowman's space and oedema. Tubulonecrosis, hyperemia and fibrosis were
noticed in the reneal tissue after day 19 of BHC intoxication. Exposure to
BHC elicited an initial dilation of bile canaliculi, enhanced secretion of bile
and cellular hypertophy on day 4. Necrotic changes like excessive vacuolation,
and karyorrhexis and karyolysis were seen on day 8. By day 10 and 15,
complete vacuolation of hepatocytes, pycnosis of nuclei and focal necrosis were
noticed.
