Abstract
______________________________________________________________________________________________________
TAdult males of the quail Coturnix coturnix were exposed
to lead acetate trihydrate in drinking water (0.1%, 0.25%, 0.5%, and 1%
for 1 to 6 months) to investigate histological and histochemical
alterations induced by lead intoxication in the kidney. Chronic exposure
to subtoxic concentrations of lead produced progressive tubular,
glomerular and interstitial damages that include tubular dilation,
vacuolar degeneration, nuclear pyknosis, mesangial hypercellularity and
proliferation, glomerular basement membrane thickening, interstitial
edema, congestion of blood capillaries and hemsiderosis. The findings
revealed that chronic exposure to lead produced significant histological
and histochemical changes in the kidney of the quail Coturnix coturnix.
Key words: Lead intoxication, kidney, quail, histology..
