Obesity is an excess of body fat frequently resulting in a significant impairment of health. Body index derived from body weight and height is widely available in Japan. However, body index cannot express the fat deposition in the body. Screening for early obesity was studied using a combination of body index and bioelectrical impedance for detecting fat deposition. Three hundred twenty-nine male subjects with normal body index participated in this study. Blood pressure, uric acid, total cholesterol, high density lipoprotein cholesterol, triglyceride, GOT, GPT, gamma-GTP, choline esterase and glucose tolerance after a 75-gram glucose load were measured. The following results were obtained. 1. Among 321 subjects with normal body index, 95 subjects had body fat exceeding 23% as measured by bioelectrical impedance. 2. By matched-pair comparison in the subjects whose body mass indices were within +/- 10% fasting plasma glucose, triglyceride, GOT, GPT, gamma-GTP and choline esterase were significantly higher and high density lipoprotein cholesterol was significantly lower in subjects with fat deposition over 23% than in the 92 matched controls with body fat less than 23%. In conclusion, bioelectrical impedance appears to be useful for detecting early stages of obesity in subjects with normal body index.

Three hundred and twenty nine obese children (206 boys, 123 girls) whose obesity index were above 40% were screened among 6,278 school-age children living in Ibaraki Prefecture. Six hundred and fifty-eight school-age children without obesity were used as controls. The mean levels of total cholesterol and triglyceride of obese boys were significantly higher than those of control boys. The mean levels of HDL-cholesterol of both boys and girls with obesity were significantly lower than those of controls. Hypercholesterolemia, hypertriglyceridemia and hypoalphalipoproteinemia in the boys with obesity were significantly more frequent than those in control boys. In the girls with obesity, hypoalphalipoproteinemia was significantly more frequent than that in control girls. Liver dysfunction (GPT > or = 40 IU/l) in obese children was significantly more frequent than in controls: Although none of controls had liver dysfunction, 24.8% of obese boys and 11.4% of obese girls had liver dysfunction. These findings indicated that atherogenic dyslipidemias and liver dysfunction were common in Japanese school-age children with obesity, especially in boys.

In accordance with the recent amendment of the Ordinance on Occupational Safety and Health, anemia (Hb, RBC), liver function (GOT, GPT, gamma-GTP), serum lipid levels (T-Chol, TG) and ECG have become essential items of the general periodic health examination. Data on these items were examined on 86 employees on whom chest radiography, blood pressure, urinalysis and past history revealed no abnormalities in periodic health examination at their companies. The subjects were 58 males and 28 females, between 34 and 66 years old (47.6 years on average). Anemia was found in 3 (3.5%), liver dysfunction in 13 (15.1%), abnormal serum lipid levels in 24 (27.9%) and ECG abnormalities in 8 (9.3%). The new periodic health examination system is thus thought to be useful in the early detection and prevention of adult diseases. To enhance this utility, it appears important to instruct those found abnormal in any parameter to have extensive examination. In discussing liver function and serum lipid level abnormalities, obesity, drinking and food intake should be considered.

The purpose of this study was to investigate the relation between body weight reduction and some complications associated with obesity. The subjects were 248 middle-aged obese persons (male 37, female 209) who participated in a weight reduction program at the Aichi Prefectural Center of Health Care from 1983 to 1990. The subjects had no severe complication, and the obesity indexes of all of them were over 120%. The program was held monthly for five months and consisted of diet (1500 kcal/day) and exercise (10000 walk steps/day). After the program, mean obesity index decreased by about 9%, and mean body weight reduction was about 5kg. Blood pressure, total cholesterol, triglyceride and GPT were significantly decreased, and HDL cholesterol was slightly increased. For each item the percentage of persons with abnormal values reduced by about 5 to 20%. From the relationship between degree of decrease of obesity and changes of the values of each item, it was estimated that some complications of obesity require greater than 5 to 10% decrease in obesity index to be affected. The value of each examination item before the program and the degree of decrease of obesity index had an effect on changes of the values, but obesity index before the program and age had little effect.

To determine hepatic diseases in obese children, biochemically and histologically, 11 obese patients with abnormal serum transaminase activities were subjected to this study. Fat accumulation in the liver was semiquantitatively graded, and histologically the 11 patients were classified into four groups; fatty liver, fatty hepatitis, fatty fibrosis and fatty cirrhosis. All patients had fat deposition in liver specimens, the grade of which did not significantly correlate with the degree of obesity. The grade of fat deposition in the liver specimens also did not significantly correlate with either serum transaminase activities or GOT/GPT ratio. Five patients were grouped into the fatty liver group, three into the fatty hepatitis group, and the remaining three patients into the fatty fibrosis group. However, no significant differences were found among the three histologically classified groups in terms of serum transaminase activities or GOT/GPT ratio. The usefulness of serum transaminase activities and GOT/GPT ratio was limited in predicting the severity of fat deposition or histological abnormality in pediatric obese patients.

We investigated the factors which may influence post-operative liver and renal function using a multiple regression analysis after isoflurane or sevoflurane anesthesia in 844 patients (ASA I or II, age 20-90 yr). Hepatic and renal surgeries were excluded from this study. The parameters examined were sex, age, degree of obesity, preoperative liver function, preoperative renal function, infection with hepatitis B or hepatitis C virus, inhalation anesthetics used, MAC.h of anesthesia, the duration of operation, blood loss, amount of blood transfusion, urine volume during operation, and surgical site. Serum GOT, GPT, total bilirubin, BUN and serum creatinine were examined on the 3rd and 7th day after surgery. An increase in serum GOT, GPT or bilirubin was observed for each of the following parameters; male, infection with hepatitis C virus, long operation, and upper abdominal surgery. Postoperative BUN and serum creatinine increased in patients with preoperative renal dysfunction, in elderly patients, and in hepatitis C carriers.

A total of 34,000 adults in Fukui City who had participated in annual health examinations at least once between 1986 and 1988, were followed for a period of 5 years. The results were as follows; (1) The mortality rate during a 5 year period was significantly lower for participants in health examinations than in nonparticipants of the same age group. (2) Mortality was significantly related to obesity, systolic and diastolic blood pressure, glucosuria, proteinuria, occult blood in urine, GOT and cholesterol in man, in women obesity, systolic and diastolic blood pressure, glucosuria, proteinuria, GOT, GPT and cholesterol were related to mortality. (3) An increase in hazard ratio with increasing degree of thinness was suggested particularly in males. (4) Hazard ratios increased with decreasing cholesterol in both men and women combined. (5) Except for hypertension which increased risk for circulatory disease, none of the above data appeared to be related to specific causes of death.

Predictive factors for toxicity and response to chemotherapy in patients with advanced head and neck cancer are seldom reported. Therefore, from a short series of patients with a histologically proven cancer, who were treated by a neo-adjuvant protocol with cisplatin and fluorouracil, routine clinical and laboratory data were investigated. ALT (alanine aminotransferase) and Hb (hemoglobin) appeared to be predictive for efficacy. By multivariate analysis (principal component analysis), these laboratory data were involved in two independent axes: one which was considered as "inflammatory" and the other as "hepatic". Initial obesity indices were associated with the former. The predictive variables for toxicity (i.e. age, serum creatinine level, weight loss and plasma cisplatin) were probably biased in this series. Nevertheless cisplatin concentration regularly increased in each cycle. Hence it was dependent on the rank of the course. According to this preliminary study, it would be of interest to conduct future investigations on acquired protein-energy malnutrition, as well as on selected soluble mediators of cellular and humoral immune response.

To evaluate the relationship between working conditions and workers' health, particularly the effect of work-related stress with change of working conditions for those with alcohol drinking habit and liver disorder, we analyzed physiological examination data and a questionnaire survey including the Japanese version of Karasek's Job Content Questionnaires (JCQ) on work-related stress, working hours, sleeping hours, alcohol consumption and cigarette smoking among male workers of a car manufacturing plant, who engaged in car sales work temporarily and then returned to manufacturing work. In the physiological examination data, the values of body mass index (BMI), GOT, GPT, gamma-GTP, TG and T-CHO rose and the prevalence of obesity and liver disorder increased during the term of car sales work. Comparing the term of car sales work with the term of car manufacturing work, the number of habitual drinkers and heavy smokers increased during the former and decreased during the latter. Increased alcohol consumption and cigarette smoking were also noted during the term of car sales work. Logistic regression analysis showed that the odds ratio of decreasing 'decision latitude (DL)' as work-related stress was statistically significant for increased alcohol consumption. The increased alcohol consumption probably contributing to the prevalence of liver disorder was assumed to be associated with work-related stress due to change of work conditions. Workers who showed liver disorder strongly complained of work-related stress, and it was assumed that the work-related stress was related to liver disorder. Longitudinal observations which take into account work-related stress, alcohol drinking habit and liver disorder must be well planned and personal traits of work-related stress always be taken into consideration.

There is strong evidence that genetic factors contribute to the development of obesity in humans as well as laboratory animals. Another important factor leading to obesity is an increase in energy intake. However, it is difficult to make normal rats obese by controlling daily food intake. There is no report of normal adult male Wistar rats becoming obese and diabetic on a high-fat diet. The aim of the present study was, therefore, to make normal adult Wistar rats obese by infusing high fat and hypercaloric diet through the cannula without disturbing the free movement and to investigate the influence of an increase in the caloric intake on body weight and glucose metabolism. High-fat hypercaloric diet (360 kcal/kg body wt./day; H group) or control diet (180 kcal/kg body wt./day; C group) was continuously infused into the stomach of normal adult male Wistar rats weighing approximately 300 g through gastric cannulas for 27 days. On day 28 after a 24-h fasting, serum concentrations of aspartate aminotransferase, alanine aminotransferase, total cholesterol, triglyceride, phospholipid, and free fatty acids (FFA) were determined, and intragastric glucose loading test (2 g/kg body wt.) was performed. The average weekly body weight gain in the H group was twice as much as that of the C group (40.0 +/- 2.4 vs. 19.4 +/- 1.9 g/week, P < 0.001). Serum levels of triglyceride, phospholipid, total cholesterol, and FFA were significantly elevated in the H group compared to those in the C group. Liver weight in the H group was significantly higher than that in the C group and showed steatosis. Pancreas weight (-13%) as well as protein (-12%), amylase (-53%) and trypsin content (-26%) were all reduced, whereas pancreatic DNA content was significantly increased in the H group compared to those in the C group. Serum glucose and insulin concentrations before and after glucose loading in the H group were significantly higher than those in the C group. Moreover, the insulin response relative to glucose response in the H group was significantly high compared to that in the C group, indicating the presence of insulin resistance. These results indicate that feeding of high-fat hypercaloric diet makes normal Wistar male adult rat obese associated with hyperlipidemia, hyperinsulinemia, and glucose intolerance.
