Mainly on the cardiovascular system of 1,175 persons were studied for a period from 1957 to 1958. The subjects were divided into two groups of normotensive and hypertensive ones. The latter group was further sub-divided into mild, moderte and severe ones. (They were examined clinically and) The following results were obtained: 1. In the group whose systolic pressure was 150-179 mmHg and the group of 180-209 mmHg, it was found that the hypertensives who had the above ranging pressure markedly increased between the ages of 40 and 60. The mild hypertension predominated among women while the moderate and severe ones among men. 2. Heredity had much to do wich the hypertension of young peodle and its effect was more remarkable among the cases of severe hypertension. The relations between heredity and hypertension were not clear with the aged people. 3. The sclerosis of the radial artery was low among the hypertensives, and it was rather high among women. 4. Regarding albuminuria. the rate of positivity increased with blood pressure and it was highest with the moderate hypertension group. 3.2% of all subjects revealed to be positive sugar in the urine and the rate of positivity increased with the blood pressure. Moreover it was closely related to the elevation of diastric pressure. No relation was discovered between the positivity of urinary urobilinogen and the blood pressure. 5. The ophthalmoscopic findings aggravated with the persons in thier sixties and about one half of that group registered as K. W. Ⅱ degrees. But it was rather better with those in their seventies. This indicated that those with unfavorable ophthalmoscopic findings mostly die in thier sixties. 6. 23.3% of those whose ophthalmoscopic findings registered as K. W. Ⅲ degrees had albuminuria. 7. With the aggravation of ophthalmoscopic findings, the sclerosis of radial artery increased.
