NOS2 and neuropathic pain: Morin restored GSH level and decreased nitrite level in the spinal cord [132] and genistein decreased the levels of ROS and MDA, increased GPx and CAT activities to combat the oxidative stress, as well as normalized nerve-injury-induced inducible nitric oxide synthase (iNOS) and neuronal nitric oxide synthase (nNOS) [135] in CCI model of neuropathic pain.
