Fig. 8From: Anti-nociceptive and desensitizing effects of olvanil on capsaicin-induced thermal hyperalgesia in the ratRepresentative traces illustrating changes in 340/380Â nm ratios in DRG cells responding to olvanil. The cell was suprafused with olvanil (100 nM for 1Â min) two times separated by 45Â min of wash-out with calcium buffer. Finally, the cell was exposed to KCl (60Â mM for 1Â min) followed by 45Â min of wash-outBack to article page
