Abstract
The effect of the exposure of Torpedo marmorata to a single dose of 400 cGy of ionizing radiation and doses of 200 cGy/week for 4 weeks has been studied. The parameters measured were the TBA reactivity and lipofuscin production, a fluorescent pigment that is thought to derive from the reaction of malonaldehyde, a peroxide-degradation product, with free amino-groups. Acute irradiation was found to generate an increase of peroxidative damage in some tissues. This effect was inhibited by acetyl homocysteine-thiolactone, a drug that increases the activity of tissue superoxide dismutase. Chronic irradiation produces a severe increase in the generation of lipofuscin.
