Itch Sensation Induced by Simultaneous Application of Pruritogens (Spatial Summation)
NCT06328530 · Status: RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 24
Last updated 2024-05-06
Summary
In This experiment, the investigators would like to design a new itch model based on the spatial summation of pruritic stimuli. The hypothesis behind this study (spatial summation) is that two simultaneous applications of pruritogens will result in higher itch sensation compared with a single application of pruritogen.
Conditions
- Histamine
- Cowhage
Interventions
- OTHER
-
Cowhage
25 spicules will be inserted in the center of the predefined skin area on the mandibular area. The spicules will be gently rubbed for 15-20 seconds in circular motion to facilitate epidermal penetration.
- OTHER
-
Histamine
Histaminergic itch will be evoked by a 1% histamine solution. A droplet of histamine solution will be placed on the predetermined area on the forearm, and the SPT lancet will be pierced through the histamine with 120 g of pressure for 1-2 seconds.
