The main etiology of morbidity and mortality in patients
with chronic diabetes is vascular complication[1]. Previous
studies suggested that the increased reactive oxygen species
(ROS) generation might be associated with the development
of vascular complications in diabetes[2]. The decreased
endothelium-dependent vasodilatation and increased vasoconstriction have been demonstrated in various vascular beds
of different animal models with diabetes[3,4]and in humans
[5]with type 1 diabetes. The biochemical pathways resulting
from hyperglycemia including glucose oxidation, the
formation of advanced glycation end-products (AGEs), and
the activation of polyol pathways are associated with the
generation of ROS and ultimately leading to lipid peroxidation and cellular damage in a vascular tissues[6]and also in
various body tissues[7]. Malondialdehyde levels are the
indicative of the extent of lipid peroxidation as a result of
oxidative degeneration of polyunsaturated fatty acids
