摘要: This study tested aspects of a new theory (Kelsey, 1986) the etiology and pathophysiology primary Raynaud’s phenomenon. phenomenon is defined as an episode vasoconstriction, or vasospasm, small cutaneous arteries arterioles in extremities that causes severe reduction blood flow corresponding decrease temperature skin affected areas (Coffman & Davies, 1975; Gifford Hines, 1957).
