Responses evoked by 10 μg of capsaicin are diminished in animals pretreated with SP-SAP. A, Responses of single WDR neurons to intradermal injection of capsaicin from vehicle-, SAP-, and SP-SAP-treated rats. Bin size is 500 msec.B, Mean ± SEM number of impulses per 15 sec interval after capsaicin. Arrows indicate the time of injection. ∗Significant difference between vehicle and SP-SAP groups. Responses to capsaicin were weaker in animals that received SP-SAP compared with those that received vehicle or SAP alone.
