Near-UV Radiation Effects on Dogfish (Mustelus canis) Lens Catalase and Antioxidant Protection

Ultraviolet radiation a or UV-A was found to increase dogfish lens opacity after a challenge of hydrogen peroxide (H2O2). In contrast, alpha-tocopherol and deferoxamine enhanced lens detoxification of H2O2 by catalase. The results support the theory that oxidation-reduction balance in the lens may c...

Description
Summary:Ultraviolet radiation a or UV-A was found to increase dogfish lens opacity after a challenge of hydrogen peroxide (H2O2). In contrast, alpha-tocopherol and deferoxamine enhanced lens detoxification of H2O2 by catalase. The results support the theory that oxidation-reduction balance in the lens may cause cataracts.
