RELATION OF LOCAL SKIN TEMPERATURE AND LOCAL SWEATING TO CUTANEOUS BLOOD FLOW

The relationship of local skin temperature and the onset of sweating to the local cutaneous blood flow was studied in the forearm and calf. T HE PURPOSE OF THE INVE TIGATION WAS TO APPRAISE THE POSSIBLE RELATION OF SWEAT GLAND ACTIVITY TO THE CUTANEOUS VASODILATATION WHICH HAS BEEN ATTRIBUTED TO BRADYKININ OR TO INTRACRA IAL TEMPERATURES. The onset of sweating was not marked by any apparently related increases in the rate of cutaneous vasodilatation. On the contrary, the onset of sw ating was follo ed often by a stabilization or ev n a decrease in the l vel of cutaneous blood flow. The relations of the latter to the local skin temperature were complex, particularly in the forearm. There appeared to be additional unidentified influences, possibly vasomotor, operating on the skin vessels during transitional phases in the relation of skin temperature to blood flow. A UTHOR
