After dialyzing for 10～20 min, SNP at a concentration of 1 μmol/L increased the induced responses to innocuous mechanical stimulation and decreased those to noxoius mechanical stimulation. The induced responses to both innocuous and noxious mechanical stimulations were all decreased after dialyzing the same dose of SNP for 20～30 min. The decrease was shown within 7～15 min dialysis when SNP was used at a concentration of 20 μmol/L.
