Abstract
Under the pressure loading of 30, 90, 180 or 270 mmHg, the blood flow and hyperemic responses were investigated in the superficial and deep skin tissues of the right heel of 9 healthy females, 20-21 year old. The temperature and blood flow in the superficial skin tissue, and the levels of oxidized, reduced and total hemoglobin in the deep tissue were monitored. The kinetic analyses were also made before, during and after the loading of above mentioned pressures at heel region for 30 minutes. The blood retention and tissue damages seemed to occur under 270 mmHg loading. The hyperemic response in the deep tissue increased as the pressure loading was strengthened. However, such an inclination was temporary and returned to normal level in a short period. Taken together the present results suggest that the superficial skin is more sensitive to pressure loading than the deep tissue under 270 mmHg loading.
