  3. 2. Superoxide dismutase 1 and cataract

    Författare :Eva Olofsson; Anders Behndig; Stefan Marklund; Marjorie Lou; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cataract; diabetes mellitus; nitric oxide; superoxide; superoxide dismutase; SOD1 null mice; Ophtalmiatrics; Oftalmiatrik; oftalmiatrik; Ophtalmology;

    Sammanfattning : Light and oxygen generate harmful reactive oxygen species (ROS) in the lens, causing biochemical changes that gradually disarrange the lens fibres resulting in light scattering and loss of transparency. In the healthy eye, this chronic exposure to oxidative stress may lead to age-related cataract. LÄS MER

  4. 3. The hyperosmolar airway : Mechanisms of reduced response to nitric oxide

    Sammanfattning : Inhaled nitric oxide (NO) relaxes smooth muscle of the airways and of pulmonary blood vessels and is used to treat lung diseases where the pulmonary vessels are constricted. NO has also been tested as a bronchodilator in asthmatic patients. LÄS MER
