Experiments made on white rats exposed to cold disclosed the following facts:(1). During the period of resistance and acclimatization to cold, the peripheral circulation shows alternate phases of vasodilation and vasoconstriction, with prevalance of the latter.(2). Complete adaptation to cold is accompanied by the establishment of a new rate of peripheral circulation, which is a light vasodilation.(3). Peripheral circulatory changes which occur during the period of resistance and acclimatization to cold are not accompanied with parallel fluctuations of the adrenaline and arterenol content of the adrenal medulla, but exposure to cold seems to increase gradually the adrenal content in both hormones until adaptation is reached. |
