Not applicable
AssayPainful sensation assessed in a visual analogue scale(VAS)
EnhancerThe experiment was conducted after capsaicin desensitization
Properties of enhancerNot applicable
Concentration50µl of 500 nmol Kallidin was diluted in 0.9% saline
Incubation timeAt various time intervals(30 seconds and each minute for 10 minutes)
Tissue permeability (value with units)Pain response obtained in nostrils after capsaicin pretreatment((50 nmol in 50 µl, everyday for 5-7 days): ~20(VAS value), the intensity of the sensation experienced with a single dose of capsaicin was considered the maximum value (i.e. 100) on the analogue scale, and all successive responses were scored in relation to this value.
Tissue SampleSolution was applied by a micropipette into the nostril of thirty-four healthy volunteers of either sex
