Radon therapy is clinically useful for the treatment of pain-related diseases. However, there have been no studies regarding the effects of radon inhalation on neuropathic pain. In this study, we aimed to determine whether radon inhalation actually induced a remission of neuropathic pain and improved the quality of life. ⋯ This study showed that inhalation of 2000 Bq/m(3) radon prevented and alleviated CCI-induced neuropathic pain in mice.

It is well known that neuropeptide Y (NPY) participates in the modulation of chronic pain, but its exact role has not yet been fully explained. In this study, we explored whether targeted delivery of NPY and its antagonists into dorsal root ganglion (DRG) modulates pain-related behaviour in rats with experimentally induced inflammatory nociception. ⋯ These findings indicate an important link between pain-related behaviour and neuroimmune actions of NPY Y1 and Y2 receptors.
