NADPH氧化酶与男性勃起功能障碍

NADPH Oxidase and Male Erectile Dysfunction

勃起功能障碍是男性的常见病和多发病。目前认为氧化应激是引起阴茎勃起功能障碍的重要机制之一。NADPH氧化酶广泛存在于机体多个系统(包括阴茎组织),发挥重要的生理功能。在多种病理情况下,NADPH氧化酶可以在阴茎组织中催化合成大量活性氧,导致过度氧化应激,从而影响阴茎勃起功能。本文就NADPH氧化酶的组成、同源物、活性调节、生理功能、在勃起功能障碍中的作用以及在勃起功能障碍治疗中的应用作一综述。

Erectile dysfunction （ED） is a common disease in men. Oxidative stress is indicated to be one of the important mechanisms of ED. NADPH oxidase expresses and plays significant psychological functions in many human organs, including the penis. In a variety of pathophysiological conditions, NADPH oxidase causes excessive oxidative stress through overproducing reactive oxygen species in the penis, and consequently induces erectile dysfunction. This paper reviews the composition, homologues, activation and physiological functions of NADPH oxidase, its role in ED, and its application in the treatment of ED.
