Roflumilast extenuates inflammation and oxidative stress in cadmium-induced hepatic and testicular injury in rats.

Roflumilast (ROF), a highly selective phosphodiesterase-4 inhibitor, has proven anti-inflammatory and immunomodulatory effects on the pulmonary system. However, the protective effects of ROF on cadmium (Cd)-induced hepatic and testicular injury has never been investigated. Adult male Sprague Dawley rats were acutely intoxicated with CdCl (3 mg/Kg, ip, qd, for 5 days).
