FIELD STUDIES ON SERUM PROTEIN

2. ON RELATIONSHIP BETWEEN SERUM PROTEIN AND BLOOD PRESSURE

Abstract

Relation between serum protein and blood pressure was investigated with 320 males and 521 females above 40 years, totalling 841 inhabitants of four villages of plain rural districts in Gunma Prefecture, with the following results :
1) There was tendency of positive correlation, though in lower degree, between serum protein and blood pressure in both sexes and through all the age groups.
2) Average serum protein value was higher for hypertension group than for non-hypertension group in both sexes and in all age groups, but especially remarkably in females.
3) Average blood pressure was high in both sexes and in all age groups in the descending order of the relative hyperproteinemia group, normal serum protein group and relative hyperproteinemia group. The same tendency was also observed with the incidence rate of hypertension.
4) No special difference for the above mentioned findings could be seen between the maximum and minimum blood pressure.
5) Average blood pressure for mountainous rural inhabitants, among whom hypoproteinemia was observed with high frequency, was lower than for plain rural inhabitants. Also incidence of hypertension and death rate from apoplexy were lower in the former.
