Abstract
Ionizing radiation interacts with living cells, causing a variety of biochemical changes depending on exposed and absorbed doses, duration of exposure, interval after exposure and susceptibility of tissues to ionizing radiation. So, it may increase the oxidative stress and damage of body organs. Alpha-lipoic acid (ALA-also known as thioctic acid) appears to be readily absorbed from an oral dose and converts easily to its reduced form, dihydrolipoic acid (DHLA), in many tissues of the body. ALA can neutralize free radicals in both fatty and watery regions of cells.
The present study has been designed to evaluate the possible efficiency of ALA as antioxidant and radio-protector against radiation induced oxidative stress in different organs (liver, kidney and heart) in rats through estimation of the activity of markers of serum liver, kidney and heart function, in addition to the histopathological differentiation of these organs by light and electron microscope.
