Role of nitric oxide in modulation of afferent impulses in cutaneous branches of somatic nerves by polarized light

Subcutaneous injection of L-NAME inhibited afferent impulse activity inn. ischiadicus andn. saphenus and abolished the increase in this activity induced by stimulation of mechanoreceptors after skin irradiation with polarized light with various spectral characteristics. Subsequent subcutaneous injection of sodium nitroprusside restored the pattern of afferent impulse activity in these nerves during repeated skin irradiation with polarized light.[PUBLICATION ABSTRACT]
