title: The effects of UV radiation and antioxidants on life span and lipid peroxidation in the rotifer Asplanchna brightwelli.
abstract: Lipid peroxidation (LP) rates and life span were determined in control and in ulraviolet (UV) irradiated rotifers of the species Asplanchna brightwelli. UV irradiation administered at 6 h of life significantly increased the rate of LP as the rotifers aged; it also produced a significant shortening of rotifer life span. Pretreatment with 20 microg/ml of vitamin E blocked the increase in LP and the decrease in life span induced by UV radiation. The antioxidant synergist 3,3'-thiodipropionic acid had no such UV-protective effect. These results indicate that the decrease in life span caused by UV radiation may be mediated through the production of lipid peroxides.
