Electrocardiographic findings in the inhabitants of the age forty and over of both sexes were compared between the inland farm village G (1, 016 persons) and that of the coastal fishing village R (1, 055 persons) in relation to different mortalities from cerebrovascular disease in the north-eastern part of Japan mainland. The ECG findings were classsified according to 9 modified system of Minnesota code of Blackburn et al. The results follow : 1) Percentage of the male subjects with normal ECG was significantly lower at the farm village H compared with those of the fishing village R. Also, for female, normal ECG was less frequently seen at the farm village, however, the difference was not significant between the two villages. 2) The frequency of the findings of high voltage among the farm villagers was almost the same level for all the age groups of both male and female, and was significantly higher compared to the fishing villagers. 3) The frequency of abnormal ST code was also higher for the farm village, but the difference between the two villages was significant only for female but not for male. 4) Downward inversion of TV1, wave was more frequently seen among the fishing villagers, however the difference between the two villages reached to the sighificance level only for female. 5 5) Frequencies of the elongated QT code, atrioventricular block code, bundle branch block code and abnormal T (C) code were increased with the advancement of age class, however, the differences between the two villages were not significant for these items.
The present paper deals with the relationship among the findings of ECG, blood pressures and ocular f undi of the inhabitants of age 40 and over in the inland farm and the coastal fishing villages of the different mortalities from cerebrovascular lesions. The results follow: 1) Blood pressure levels were significantly higher for inhabitants in the farm village, for male in systolic (P<0.01) and for female in diastolic (P<0.02). 2) Prevalence of hypertensive changes in ocular f undi was high in the fishing village, whereas that of the sclerotic changes was higher in the farm village, and the differences were both significant. 3) Frequency of the abnormal ECG findings, as of the final classification code, high voltage code, ST change code and T change code were higher for hypertension group compared with those of normotension and borderline groups. 4) Prevalence of the higher degree changes of the findings of ocular fundi of both hypertensive and sclerotic (H2-4 and S2-4) were high for the hypertension group. 5) Complication of the abnormalities of hypertension, changes of ocular fundi and ECG findings was higher for the farm villagers compared with that of the fishing villagers.
Stature, body weight, maximum glabello-occipital length, maximum cephalic breadth, anatomical face length, face breadth, height of nose, length of nasal bone and nasal breadth of 889 healthy men of the age 18 to 29 years at a air force base camp are measured in order to carry out an epidemiological research on the human facial cranial components, especially on external nose forms. These data are compared and discussed in the epidemiological methods. The results follow : (1) Stature, maximum glabello-occipital length, maximum cephalic breadth, cephalic index, height of nose, length of nasal bone and relative height of nose are significantly higher in the men brought up in urban than in rural districts, but maximum glabello-occipital length and nasal index are significantly higher in the latter than in the former. (2) Cephalic index, facial index of Kollman, height of nose and relative height of nose are: significantly higher in the sons of non-farmers than that of farmers. Rohrer's index, maximum glabello-occipital length, face breadth and nasal index are significantly higher in the latter than in the former. (3) Maximum glabello-occipital length, anatomical face length, height of nose, length of nasal bone, relative height of nose and relative length of nasal bone are significantly higher in the men come from the northern region than from the western y region of Japan. Cephalic index and nasal index are significantly higher in the latter than in the former. Maximum glabello-occipital length and relative height of nose are significantly higher in the men come from the northern region than in the men from the central of Japan, and the differences between the men from the central and the western region are not significant.
