Brief Summary:
Microvascular dysfunctions are critical events in several diseases including diabetes. This study will develop a methodology for microvascular investigation in human skin. The purpose of the study is to investigate the physiological response of the cutaneous microcirculation to physical, thermal, mechanical or chemical stimulations.

Condition or disease Intervention/treatment
Healthy Volunteers Device: pressure strain system, iontophoresis Drug: scopolamin Drug: emla Drug: capsaicin Drug: aspirin Drug: clopidogrel Drug: celecoxib Drug: indomethacin Drug: acetylcholine Drug: sodium nitroprusside Drug: brethyllium Device: general and local heating

Detailed Description:
This study has investigated various aspects of the physiology of the microcirculation in the past years and is still recruiting under parallel protocols of physiological investigations of the neurovascular control of the cutaneous microcirculation.
