Pb caused red in kidney GGT and NAG, decline in GSH,<br />

catalase, SOD, GPx and Glut reductase, and increased MDA.<br />

Lipoic acid<br />

+DMSA restored these changes.<br />

Thiamine reduced Pb content and MDA levels <strong>of</strong> both liver<br />

and kidney and improved pathology.<br />

Pb in liver, kidney and brain reduced by vit E + EDTA<br />

treatment. MDA increased by Pb in all 3 organs but decreased<br />

by vit E + EDTA.<br />

GSH, non-protein SH, lysine and methionine increased in liver<br />

and non-prot SH, glycine, cysteine and cystathionine in<br />

kidney. Cysteine reduced in plasma.
