Abstract
In order to find a special risk group among hypertensjve snbjects borh cotd Ptessor and capillary resistance tests have heen described in normal and hypertensive subjects. The cap illaryresistance has been shown to decrease with age in males. The level of resistancdiseas in fema-les was considered to have closer associations with room temperature, allergic esand bopy-build. The cold Pressor test also revelaed similar associations with painful sensation on immensing a hand in waters at 4 degrees centigrade and habitual exposure to cold stlmuius in daily life.
Although in cole prdsser test the incidence of hypertensive subjects was lowest in normodeaotors, relative high incidence of hypertensive subjects was found in hyporeactors and lower resistance group, particularly in males. In females the capillary resistance test was considered to have lesser significance than in males, and the hyperreactor or hyporeactor had more association with the incidence of hypertensive subjects.
