The recent trend of death rates from heart diseases, respectively at farm villages, fishing hamlets, and large towns in Japan, was examined in the variety of existing vital statistics. The chief conclusions are as follows. The trend of crude death rate from heart diseases, for the past ten years, has been year by year rather increasing. Now, examining the death rate by age groups, we find that, at the advanced age over eighty, it has by bits increased, but, at the age below that, it has rather decreased. As for the type of diseases, ischemic heart disease has increased a little at the advanced age, but below the middle age, it has rather decreased, and chronic rheumatic and hypertensive heart diseases have also decreased. On the other hand, heart failure and other heart diseases have rather increased. Examining the trend of death rates from heart diseases for the past 25 years, classified, by using the proportion of industrial inhabitants, into the prefecture of farming, that of fishing, and large cities, we find that the death rate from ischemic heart diseases has been high as to the advanced age in large cities, and the death rate from heart failure and other heart diseases has been high as to the advanced and middle ages in the prefecture of farming. From the above, it has become clear that the chief cause of the increases of heart diseases of recent years is the increase of heart failure and other heart diseases, and that it is chiefly discernible at farming villages. Next, we investigated the death rate. from heart diseases separately of villeges which may intimately be related to our lives, in respect of the three villages and towns in the West Izu. The result is that the death rate is high in the towns, and then in the district of farming, and is the lowest in that of fishing. This kind of examination is expected to be done widely in Japan, and the universal conclusion to be got. In addition to the above, we investigated the trend of death rate from heart diseases, from the “ Special Report of Vital Statistics: Occupational and Industrial Aspect”, and we clarified and reported that the death rate of agriculture, forestry and fishing workers, as well as urban occupation, was high in degree, and that, from the investigation separately of the cities, towns and villages of Chiba Prefecture, there was a statistically significant relation between the ratio of agricultural population and the death rate from heart diseases.
The purpose of this study is to make clear a comprehensive relationship between two groups of serum enzyme activity and nutrient intakes. The first group of measurement include serum GOT, GPT, ALP activity and the second group of measurements include protein, fat, carbohydorate, vitamin A, B1, B2, C, animal protein, animal fat, age, and weight. These figures are taken from the epidemiological survey of Tokushima prefecture, including 252 males and 383 females, investigated from 1975 to 1980. Appling the canonical correlation analysis, we found the following results. 1) In male, only two canonical correlations were statistically significant. The serum GOT and GPT activity related to body weight, further serum GOT activity was effected quality of food intakes. 2) In Female, three canonical correlations were statistically significant. Both serum GOT and GPT activity related to protein intakes. High correlations were observed between serum GOT activty and vitamin B1, between serum GPT activity and vitamin C, between serum ALP activity and age.
A survey was carried out in a rural area in Thailand as a part of the study on the physical development and nutritional status of children of developing countries in Asia. Four hundred and sixty-three school children of both sexes, from 6 to 14 years of age, had anthropometric measurements and examinations of clinical signs related to nutritional deficiencies. Blood, urine and feces were also exaimined. 1) Thai children were remarkably smaller than Japanese and growth retardation was observed at 21.4% and 37.3% of those in age groups 6-9 and 10-14 years, respectively. And judging from the weight-for-height, about one-fourth of them were considered malnourished in varying degrees 2) Upper arm muscle circumference, calculated with upper arm circumference and subcutaneous skinfold of the same place, revealed that the development of muscle was obviously retarded. 3) Signs of hypovitaminoses such as xerosis of the skin, decreased patellar reflex, cheilosis, angular lesion were frequently observed. 4) Mean values of hemoglobin and serum iron concentrations were low in general and about 20% of the children were judged anemic according to the WHO criteria for nutritional anemias. Cholesterol values were also lower than those of Japanese and American children 5) The overall positive rate of intestinal parasites' eggs was 43.2% and hookworm eggs were most frequently observed, follwed by Giardia lambria For the improvement of growth and nutritional status of Thai children, the preventive measures against parasitic and infectious diseases through improvement of environmental hygiene are essential as well as food supply.
We began gastric mass survey at our hospital in May, 1980. During 3 years and 8 months since then, (May, 1980-December, 1983) we performed screening examinations to 16, 341 people by indirect radiography, and checked 2, 824 cases (17.3%) for thorough examination. Among these cases, 2, 083 (73.8%) received endoscopic examination actually, and 55 cases of gastric cancer were discovered. The discovery rate of gastric cancer was 0.336 per cent. 35 cases of these 55 gastric cancer were operated in the surgical department of our hospital. 34 cases were resected (rate of resection was 97.1%) and 33 cases were resected curatively (rate of curative resection was 94.3%). These results were better than that of gastric cancer cases from out-patient clinic of the same period. The results of cases from out-patient clinic of our hospital were: total number of cases 321, resected cases 254 (79.1%), curative resection 189 cases (58.9%), respectively.
On the basis of 803 answers of Yes/No questionaires about urinary incontinence from the females in Kijimadaira village and at the Hokushin General Hospital, the actual incidence was discussed especially for the purpose of the comparison between the female farmers and nurses including nurse students with urinary incontinence.
A study was made on and-ATLA antibody among general inhabitants, those with hematologic disease and those with hepatic disease in Nagano Prefecture. Among 2, 299 inhabitants (990 males and 1, 309 females), anti-ATLA antibody was found to be positive in two males (0.1 %) The number of patients with hematologic disease was 155. Of them, malignant lymphoma accounted for 50 (T: 24.3 %, B: 37.8 %), acute leukemia 32 and other hematologic malignancy 28. No ATL was found among them. It was revealed that 56 of them underwent transfusion ranging from 2 to 346 units of blood, averaging at 49.7 units. The number of person whose anti-ATLA antibody was positive was one only, who was diagnosed as AML and was transfused 170 units. Of 42 patients with hepatic disease, HB virus-related liver disease (hepatitis, cirrhosis, hepatocellular carcinoma) accounted for 10, non-B group HBAg (-) for 18, alcoholic liver dysfunction 5 and other hepatic disorders 9. Three out of these 42 patients were found to be positive for anti-ATLA antibody, each three patients belonged to the “non-B” group (3/18, 16.6 %). The total number of positivist was thus six. Of them, five had a history of transfusion, and all five positivists excluding the one with AML were suffering from hepatic disease with HBAg (-). From the above, it was considered that in Nagano Prefecture, those whose anti-ATLA antibody was positive were conspicuously small in number, but main cause of the positivity was attributable to the transfusion. Most of the positivists were suffered from non-B hepatic disease with a history of transfusion, and the number of positivist was significantly greater even when compared with patients with hematologic disease with frequent transfusion. Accordingly, it is suggested that some of the hepatic diseases with HBAg (-) might be associated with HTLV.
During the pruning season, tea growers work longer hours, and many present symptoms of ifferent varieties from overwork. A recent survey conducted by the authors showed that increased loads are placed on the elbow of the farmers engaged in tea-tree pruning. In some cases, changes in the elbow joint structure were visible on X-ray films. 1. Total number of the subjects covered: 47 (25 men and 22 women) 2. Age: 32-89 (53.7±12.2) 3. Average number of years engaged in the work: 31.8±15.7 for men: 26.9±4.53 for women 4. Working hours per day: 8.30±2.51 (Thirteen persons or 27.6% said that they work more than nine hours.) 5. Chief complaints and symptoms: pain in the elbow region and the outside of the forearm 6. Radiographic findings: arthropathy 58.3%: normal 41.7% 7. Impairment in mobility of the joint: minor degree
