Does nitric oxide inhibit the release of acetylcholine in the isolated retina?
The NO-induced decrease of ACh release is probably due to an NO-induced increase of GABAergic system inhibition.
This study illustrates that the association between tender points and pain is not restricted to the clinically defined subgroup with chronic widespread pain. Given that widespread pain and tender points have previously been linked with distress, this might reflect lesser degrees, or earlier phases of the somatisation of distress.
