Outline of Final Research Achievements

The purpose of this study was to clarify the role of skin cold receptor function in the local control of skin blood flow (SkBF) and the characteristics of the SkBF control in individuals with a cold constitution. Topical application of menthol, cold receptor agonist, did not alter the SkBF response to local skin cooling, suggesting that cold receptor function plays a minor role in the local control of cutaneous vasoconstriction. It was suggested that the individuals with a cold constitution possess a specific SkBF controlling system that is characterized by higher adrenergic sensitivity for greater cutaneous vasoconstriction in the distal portion of the lower extremities during whole-body and local skin cooling.
