Summary

In order to validate the accuracy and reliability of the histamine skin prick model for histaminergic itch and vasodilation, the dermal blood flow response induced by a histamine skin prick will be evaluated after the administration of certain antipruritics. Besides, the influence of these antipruritics on the dermal blood flow response induced by the topical application of cinnamaldehyde and capsaicin will be evaluated. Changes in dermal blood flow will be measured with laser speckle contrast imaging.
