Cold-induced alteration of cutaneous blood flow, measured with laser-Doppler flowmetry, was studied in a rat tail model of nonfreezing cold injury (NFCI). The NFCI-inducing condition consisted of prolonged tail immersion in 1° water. Before exposure to the injury condition, tail blood flow (laser Doppler flux) during brief 3° immersion showed cold-induced cycles of vasoconstriction followed by cold-induced vasodilation (CIYD). Tail temperature exhibited cyclic patterns similar to blood flow in response to cold water immersion. Cold exposures to 1° for 1 or 3 hr induced no systematic change; however, cold exposures of 6 or 9 hr induced profound and long-lasting blood flow and temperature deviations.
