When male rats, each bearing an indwelling femoral arterial cannula, were exposed abruptly to cold (5 degrees C), systolic, diastolic, and mean blood pressures increased within 1 hr to levels significantly above those measured prior to exposure to cold. Blood pressures reached maximal levels within 2 hr of exposure to cold and remained elevated during the next seven days. Heart rates, measured at the same time, responded similarly. When cannulated rats that had been exposed to cold for four… CONTINUE READING
