To evaluate the relation between the working conditions and the workers' health, particularly the prevalences of obesity, liver disorder and hyperlipidemia, we analyzed physiological examination data and the questionnaire survey about life behaviors and working conditions during the terms of car manufacturing work and car sales work among 61 male subjects. In the physiological examination data, compared with the term of car manufacturing work, the values of body weight, body mass index (BMI), GOT, GPT, gamma-GTP, TG and T-CHO elevated and the prevalences of obesity and liver disorder increased during the term of car sales work. During the term of car sales work, the prevalences of alcohol drinkers and cigarette smokers increased and the changes of food intake behaviors were noted. It was estimated that the changes of food intake behaviors associated with the differences of working conditions contributed increasing number of obesity and liver disorder that was based on fatty liver caused by hyperlipidemia. These results of this study suggested that working conditions associated with the prevalences of obesity, liver disorder and hyperlipidemia were important to conduct the effective health education in the present occupational health administration.

We retrospectively examined the issues that concern parents of obese children to determine the most effective means of motivating them to seek treatment for obesity in their children. Children with an obesity index > or = 40%, aged six to 12 years, were screened in Kagoshima City in 1992. Parents were notified if their children needed an evaluation that included a family history and measurements of the blood pressure, total cholesterol, high density lipoprotein (HDL)-cholesterol, atherogenic index (ASI), triglycerides, aspartate aminotransferase (AST) and alanine aminotransferase (ALT). Parents were informed of the results of the evaluation and invited to attend a lecture on the treatment of obesity in children. A total of 378 obese children were evaluated. However, the parents of only 39 children attended the lecture. Children whose parents attended had higher mean total levels of cholesterol (190 +/- 25 vs 175 +/- 28, P < 0.01) and ASI values (3.2 +/- 0.9 vs 2.7 +/- 0.9, P < 0.02) than those whose parents did not attend. There were no significant differences in other factors. Only 4.2% of parents whose children showed no abnormal values, except for obesity, attended the lecture, compared with 20.3% (P < 0.01) or 16.9% (P < 0.05) of parents whose children had abnormal levels of cholesterol or abnormal ASI. Parents may be more concerned about hypercholesterolemia or arteriosclerosis than obesity per se. We should perhaps use the total cholesterol or ASI values, not just the severity of obesity, to motivate parents to enter their children into treatment programs for obesity.

The mitochondrial FAD-linked enzyme glycerophosphate dehydrogenase plays a key role in the pancreatic B-cell glucose sensing device. In the present study, the activity of this enzyme was examined in islets of fa/fa rats in which inherited diabetes mellitus is associated with obesity, hyperinsulinism and severe insulin resistance. The specific activity of both FAD-linked glycerophosphate dehydrogenase and glutamate dehydrogenase were decreased in islet and liver homogenates prepared from fa/fa, as compared to Fa/Fa, rats, this coinciding with a low ratio between glutamateoxalacetate and glutamate-pyruvate transaminase activity in both islet and liver extracts, islet hyperplasia, hyperinsulinemia and hepatic steatosis in the hyperglycemic fa/fa rats. It is speculated that a low activity of FAD-linked glycerophosphate dehydrogenase in the pancreatic B-cell may participate to the perturbation of glucose homeostasis in fa/fa rats, like in other animal models of non-insulin-dependent diabetes mellitus.

Plasminogen activator inhibitor type-1 (PAI-1) is a key determinant of the fibrinolytic capacity. Its activity correlates with most of the characteristic features of insulin resistance syndrome, i.e. obesity, high blood pressure and hyperlipidemia. We measured plasma PAI-1 antigen levels in 131 asymptomatic men (aged 44.2 +/- 11 years) who had been referred for hyperlipidemia. Those taking medication and those with a secondary hyperlipidemia were excluded. We confirmed the correlation between PAI-1 levels and the following variables: body mass index, blood pressure, triglyceride concentration, and blood glucose and insulin levels before and after an oral glucose tolerance test. We also found a significant and independent correlation between PAI-1 and the concentration of the hepatic enzymes glutamyl transferase, alanine aminotransferase and aspartate aminotransferase. Mild liver abnormalities (presumably steatosis) may thus be one of the factors accounting for high plasma PAI-1 levels in hyperlipidemic patients.

In previous studies we reported that the abnormality of the gamma-GTP level was found not only in hepatobiliary diseases but also in obesity and ingestion of alcohol in healthy individuals. In relation to this results, the present study deals with the relationship between abnormal gamma-GTP level in serum on the one hand and obesity and ingestion of alcohol on the other hand on the basis of test data for 1493 cases (1256 male cases, 237 female cases) who were examined in the short-term human dry dock managed by the Fukuoka University Hospital. To observe how results of various measurements including the degree of obesity and the amount of alcohol ingested exert effects on one another, principle component analysis was done by means of SAS statistic package for computer analysis. In men, as the first principle main components, obesity rate, Hb, Ht, RBC, GPT, gamma-GTP, LAP, GOT, triglyceride and total protein were extracted. As the second main principle components, alcohol, gamma-GTP, MCH, MCV, and HDL were extracted. Theses result demonstrate that the obesity is accompanied by variations in Hb, Ht, RBC and triglyceride and that digestion of alcohol is accompanied by variations in MCH, MCV and HDL in male. In women, components related to erythrocyte and transaminase along with the degree of obesity were extracted as the first main principle components, and principle components related to erythrocyte and alcohol were extracted as the second main components. In either case, alcohol and gamma-GTP were not included.

Multiple regression analysis in 1493 cases (1256 male cases, 237 female cases) who were examined in the short-term human dry dock managed by the Fukuoka University Hospital, was done with gamma-GTP as the dependent variable and other parameters as the independent variables. As the result, 16 variables including LAP, alcohol, GPT, triglyceride, HDL and obesity rate were selected as the variables explaining gamma-GTP by stepwise methods in men. The standard regression coefficient of alcohol is shown to be greater than that of obesity on gamma-GTP. On the contrary, neither alcohol nor the obesity rate was included in this regression formula in women.

The objective was to determine the effects of persistent obesity on amino acid enzymes in white (WAT) and brown (BAT) adipose tissues. Dietary obesity was induced by feeding a cafeteria diet ad libitum for 3 months, then it was removed and the obese animals received the same diet as controls for 5 months. Dietary-induced obesity was persistent as obese rats showed a stable, higher body weight than controls (26%). Key enzymes of alpha-amino nitrogen metabolism were studied and results showed reduced activities in obese rats: glutamine synthetase (45%), AMP deaminase (52%), alanine aminotransferase (66%) and glutamate dehydrogenase (68%) in BAT, whereas WAT of obese animals only showed lower aspartate aminotransferase activity (47%) with respect to the controls. We can conclude that these adaptations in amino acid metabolism were exclusively dependent on the obese status as they were observed in an obesity model in which obese rats eat the same diet as controls.

To evaluate if any pretreatment characteristics of patients with chronic hepatitis C (HCV) can be used to predict response to the current recommended dose (3 million units three times a week) and higher doses of interferon-alpha (IFN), we retrospectively assessed the response of 37 patients with HCV who were treated with IFN. Sixteen patients (43%) responded to the standard dose of IFN with normalization of ALT. Weight and liver histology were found to be significant factors for response. The responders weighed significantly less than nonresponders (161.8 +/- 35.5 lb versus 200.3 +/- 45.4 lb, P = 0.008). Seventy-five percent of patients with chronic lobular or persistent hepatitis were responders, whereas only 28% of patients with more advanced hepatitis responded (P = 0.01). There was no correlation between the degree of bile duct damage or steatosis and response rate. This study suggests that obesity and severe histologic injury are negative predictive factors of response to the current recommended dose of IFN. The adequacy of the current recommended dose of IFN in overweight patients needs to be investigated.

The risk for developing acute liver failure after halothane exposition was calculated between 1:8,000 and 1:36,000. The case report given on a 22 year old man with halothane-induced hepatic failure is unusual, because the typical risk factors as age over 40, female sex, obesity, and previous exposure to halothane were not present. Two days after exposure to halothane the patient suffered acute liver failure with severe coagulopathy (factor V = 5% activity), and encephalopathy grade IV complicated by renal failure and respiratory insufficiency. Maximal increases of enzymes in blood were AST 3900 U/L, ALT 2570 U/L, LDH 10600 U/L. After six days the patient underwent liver transplantation with complete anuria and instable circulation. Explanted liver showed massive necrosis (70% of parenchyma) and fatty changes. The liver transplant had immediately a good function and renal failure resolved within three days. In the follow-up of 3 1/2 years the patient suffered no further complications. Culturing the patient's lymphocytes in the lymphocyte transformation test a strong reaction could be detected with a stimulatory index of 20. Maximal proliferation was observed when lymphocytes were incubated with plasma metabolites of a volunteer drawn 120 minutes after anesthesia with halothane was started.

Circulatory system examinations performed on first-grade pupils of junior high schools (12 years old; N = 1,204), identified 105 high-risk pupils with arteriosclerosis-promoting factors. These pupils were consulted on life-style modification, emphasizing nutrition and exercise, and encouraged to practice personal health management and self-monitoring. Reduction and correction of high risk factors were studied in these subjects, based on review of results of health examinations performed regularly up to the time of their graduation. Results are as follows: 1. Averages for obesity grade (for both sexes) in the second and the third years were significantly lower than that in the first year. Based on a general reference value > or = 20%, improvements were observed in 22.5% of males and 50.0% of females. 2. In both sexes average total cholesterol (TC) and triglyceride (TG) were lower in the second and the third years than in the first year, and a significant increase in HDL cholesterol was seen. With regard to a general reference value > or = 3.0 for AI (Atherogenic Index) calculated using TC and HDL cholesterol, improvements (reduction) were observed in 29.4%, of males and 46.2% of females. 3. While the numbers of subjects with elevated SBP, DBP, GPT, FPG and BUN were few, there were significant decreases in averages in the second and third years compared with those in the first year. Using general reference values, improvements in these risks were seen in 100% for all values except for GPT where 75.0% showed improvement. 4. Comparison of grouped distribution of summed values of examination results between the first year and the third year, showed improvements (reduction and correction of risks) in 69 pupils (65.7%), while 30 pupils (28.6%) remained in the same group with no improvement and 6 pupils (5.7%) turned for the worse, dropping one rank.(ABSTRACT TRUNCATED AT 250 WORDS)
