A STUDY ON THE PREVENTION OF HYPERTENSION : A Method for Determining Basal Blood Pressure with Sodium Nitrite

Abstract

The purpose of this study is to determine the basal blood pressure with sodium nitrite. To persons with maximum pressure over 130 mm Hg and minimum pressure over 80 mm Hg sodium nitrite was injected to examine the degree of decrease of pressure and pressure after decrease. The relationship between E.C.G. as well as fundi findings were also investigated. Results are as follows: 1. The higher the maximum pressure, the less its decrease after injection. 2. There were found a good number of people with arterioloscrelotic changes at fundi among those whose pressures were under 150 mm Hg after injection. In general, the higher the pressure, the more severe these findings. 3. There were many who showed the less decrease of pressure had the more changes at fundi. 4. Those with the higher pressure or the less decrease of it after sodium nitrite injection had the more severe findings of E.C.G. at the same time the arterioloscrelotic changes at fundi. Considering from the above results, blood pressures before and after administration of sodium nitrite in a resting state may serve as indicators of arterioloscrelosis and their measurement is thought to be an useful method for determining the basal blood pressure.
