2.3. Effects on oxidative status in kidney
Pb-induced renal dysfunction can be classified as acute and
chronic nephropathy, and occurs mostly at high levels of Pb exposure
(>60 μg/dL blood) but damage at lower levels has also been
reported (~10 μg/dL blood) (Grant, 2008). Acute Pb-induced nephropathy
is characterized functionally by a generalized deficit of
tubular transport mechanisms (Fanconi syndrome), morphologically
by the appearance of degenerative changes in the tubular
epithelium and the nuclear inclusion bodies containing Pb protein
complexes. Although the exact mechanism of renal Pb toxicity is
not completely understood, numerous experimental data have shown
that oxidative stress has an important role
