Studies on catalase in ageing Zaprionus paravittiger (Diptera) with special reference to an antioxidant feeding.
Zaprionus paravittiger fed with an antioxidant (sodium hypophosphite, 1 X 10(3) microM) supplemented diet exhibited adaptive compensatory responses in catalase activity (quantitative as well as qualitative). The longevity and catalase activity were found to be positively linked. The study denotes that free radical formation and antioxygenic defenses are closely associated and are the possible determinants of life span and ageing.
