SURVEY ON SERUM LIPOPROTEIN OF FARMERS IN THE RICE FARMING AREA OF THE NORTH-EASTERN JAPAN

Abstract

In the north-eastern part of Japan incidence of hypertention is very high among farmers, and their death rate from cerebral hemorrhage is also high, though their daily intake of fat is estimated at some 5 to 10% of their total caloric intake. The author studied the serum lipoprotein by the electrophoretic method with a view to contributing to the solution of the problem of lipid-metabolism of farmers. As a result, it was found that, β-lipoprotein:α-lipoprotein was high in the hypertensive group and that it was correlated with the concentration of serum cholesterol, though their mean values appeared to be low as compared with those of the patients of hypertensive or coronary diseases in other districts.
