Age-Related Features of Cataractogenesis in Salmon Fry. 2. Biochemical Features of Lens during Cataractogenesis

We studied biochemical features of the lipid and phospholipid composition and patter of fatty acid spectra in lenses of one and two year old salmons bearing cataracts. The lipid complex of lenses of diseased fish underwent significant changes. Cataractogenesis was accompanied by enhanced free radical oxidation and accumulation of malone dialdehyde in lenses of salmons of various ages. The intensification of oxidative processes was synchronized with the decreased level of antioxidant protection (reduced glutathione, vitamins A and E). The activity of Ca2+-dependent proteolytic enzymes in lenses was determined and its decrease in the case of cataract was shown.
