JOURNAL FREE ACCESSThe residue levels of three kinds of organochlorines, BHC, DDT and PCB, in the serum were determined in farmers (40-59 years old, n=211), non-farmars (40-59 years old, n =27) and high school students (15-18 years old, n=56) to clarify the factors that contributed to the accumulation of those three compounds in the blood of farmers and rural inhabitants. The average values of those compounds were found to be 9.1±5.0 ppb for B-BHC, 9.2±6.3 ppb for pp'-DDE and 7.1 ±5.7 ppb for PCB. There was marked difference in the value between districts in which the subjects live. The subjects could be divided into the lower concentration group and higher concentration group, showing high discrimination ratio (72-83%) by Hayashi's quantification theory II. Statistical analysis showed that the factors contributing to the accumnlation of those compounds in the present subjects are related with digestion of chicken and fish, Hb concentration, serum cholinesterase activity, liver function and serum trigliceride and cholesterol levels, and use of organochlorines and other pesticides, duration and the mumber of days of pesticide spraying, experience of pesticide poisoing, cultivation of specific crops. Those results, in greater part, supported the general recognition that organochlorine residues in human body might be regulated by changning eating patterns and avoiding those food items containing those chemical compounds. On the other hand, attention should be focused on the exposure of those compounds through the use of specific pesticides including those compounds. And further investigation is necessary for clarifying the contributing factors to the accumulation of those compounds in human body especially in the higher residue group discriminated in the present study.View full abstractDownload PDF (1606K) -

JOURNAL FREE ACCESSThe work of viniculturists consists of a number of overhead work for hours in a standing position. In order to improve working postures and reduce musculoskeletal complaints of viniculturists, a tricycle and an electric-driven tricycle for vinicultural use were invented. Investigation was performed during the thinning out of grapes by comparing three different working methods, i. e., traditional standing overhead work, work using a tricycle, and work using an electric-driven tricycle. The three different working methods were employed for four days, each by three viniculturists.
The subjects were questioned whether they had musculoskeletal complaints and general fatigue sensations four times a day during the investigation. For each different working method, the working hours and the amount of work of each subject were measured. The subjects were also asked to evaluate each working method by themselves. The work aided by the electric-driven tricycle was effective in decreasing the complaints of pain in the lower back (lumbago) and dullness of the legs. The work aided by electric-driven tricycle also showed higher efficiency than either traditional standing work or the work aided by tricycle. The electric-driven trycycle also received higher evaluation because of its easy drivability. These results lead to the conclusion that by adding some more improvements on the electric-driven tricycle, it could be introduced to viniculturists for practical use.View full abstractDownload PDF (1048K) -

JOURNAL FREE ACCESSTo find a link between lifestyle and arteriosclerosis, the serum lipid values were studied in those who had entered our hospital for a thorough physical examination. The subjects were 136 men and 31 women. They were divided into six groups. 1st: neither drinking nor smoking habits (24 cases). 2nd: 20 or 40 grams of ethyl alcohol daily and no smoking habit (45 cases). 3rd: more than 40 grams daily and more than 10 cigarettes (21 cases). 4th: 20 grams daily and more than 10 cigarettes (25 cases). 5th: no drinking habit and more than 10 cigarettes daily (21 cases). 6th: women who had neither drinking nor smoking habits (31 cases).
The 2nd group was a control group, and was compared with each group. It was found that only TG values were significantly high in the 3rd group. HDL-C values were significantly low in the 5th group. There were no significant differences in the 1st and 4th groups. T-CHO and LDL-C values were significantly high in the 6th group. These facts suggest that it is difficult to correlate both drinking and smoking habits with the incidence of arteriosclerosis. And perhaps it is the same in women, because LDL-C values were high in women, but at the same time HDL-C values were high.View full abstractDownload PDF (428K) -

JOURNAL FREE ACCESSClinical research was carried out on stomach cancer cases treated in the surgery department of our hospital, which provides medical services to the populace in the southern part of Fukushima Prefecture.
During the 10-year period between Jan. 1981 and Dec. 1990, a total of 641 cases were referred to surgery. Of the total, 568 cases or 88.6% were operated on and 501 or 78.2% were radical gastrectomy cases.
When a careful check was made on these cases with respect of staging, histology, invasion degree and lymph node metastasis, it was found that the ratio of early stage stomach cancer cases was increasing steadfastly year after year.
Regarding the 5-year survival rate, 63.7% was scored by the operated cases and 73.2% by radical gastrectomy cases. These rates were up by 18.6% and 17.0% from five years ago. The above findings indicate that improvement in treatment results is due to technical progress in detection of gastric cancer at early stages.View full abstractDownload PDF (401K) -

JOURNAL FREE ACCESSIn order to know the present state of mass survey for large-bowel cancer in rural areas, we gathered the results of colorectal screening in 1989 from 45 hospitals or cancer detection center related to agricultural cooperatives of all over Japan.
In all of the 45 institutions, method of screening was fecal occult blood test, and in most of them, the stool study was immunological, of one day, and without meal restriction. Methods of further precise examination such as barium enema, total colonoscopy, sigmiodoscopy, or proctoscopy, solely or combined, were employed depending to the facilities.
The total number of examinees were 194, 834, and 8, 523 (4.4%) had a positive reaction for occult blood. Further precise examinations were performed in 4, 351 (59.7%) examinees, and 148 cases of large-bowel cancer were detected. The detective rate of cancer in total examinees was 0.08%. Among these 148 cases of colorectal cancer, 43 cases (51.8%) were in early stage. Examinees in their fifties were the most in number, and both the rate of positive reaction and the rate of cancer detection were increased as the age gets older.View full abstractDownload PDF (720K) -
