TY - JOUR T1 - THE EFFECT OF LEAD ON ENDOTHELIAL PERMEABILITY OF AORTA TT - اثر سرب برنفوذپذیری آندوتلیال آئورت JF - RJMS JO - RJMS VL - 8 IS - 23 UR - http://rjms.iums.ac.ir/article-1-324-en.html Y1 - 2001 SP - 76 EP - 82 N2 -  The side effects of toxic trace elements such as lead in the exposed subjects have been investigated in past years. Lead disturbs microvascular system, and changes the plasma level of lipids and lipoproteins. In this research the role of lead in plasma lipids and endothelial permeability of aorta were studied.   Two groups of white male rabbits were under investigation for forty days. Group I were used lead water drinking contained 54.7 ppm lead during the experiment. The other group had drinking water with no lead. The plasma lipids, lipoproteins, lead, iron, total iron bounding capacity, and calcium were measured before and after the experiments. Both groups also were subjected to determination of endothelial permeability of aorta, direct blood pressure, and other pathological findings.   The results indicated no weight gain in group I animals, while other group animals weight were increased significantly during the experiment (P M3 ER -
