Health examinations of 108 workers exposed to vinyl chloride monomer (VCM) at a Japanese chemical plant were carried out in 1979. The polymerization of vinyl chloride was started at the plant in 1949. In this study, the highest concentration of VCM in autoclaves was determined to be 250 ppm in 1961. However, the workers at the plant had been exposed to higher concentrations of VCM several times before 1960. More recent VCM exposure was considered negligible. Examinations assessed data on age, height, weight, obesity index, sake consumption, VCM exposure concentration, latent period, cumulative exposure, ICG (indocyano green test), serum bilirubin, GOT (glutamic oxaloacetic transaminase), GPT (glutamic pyruvic transaminase), A1-P (alkaline phosphatase), GGT(gamma-glutamyl transpeptidase), ZTT (zinc turbidity test), LDH (lactate dehydrogenase), cholesterol, TTT (thymol turbidity test), A/G (albumin globulin ratio), and thrombocytes. Variation in VCM exposure did not affect tests of pigment excretion from the liver, such as ICG; thrombocytes; and enzyme activity (such as GPT); nor bilirubin or flocculation reaction in serum.

Methods of clinico-instrumental investigation and biochemical monitoring (CPK and its membranous fraction) were employed for examination of 432 patients with acute myocardial infarction (AMI). Among them there were patients with an uncomplicated course of disease (19.4%), recurrences (13.7%) and AMI spreading (9%). Lung edema, a cardiogenic shock, ventricular fibrillation and complicated cardiac rhythm disorders were not detected on the 1st day of disease. Clinico-anamnestic data provided no opportunity for defining factors promoting AMI recurrences whereas AMI spreading frequently developed in patients with repeated AMI, suffering from essential hypertension, obesity and heart failure. Higher diastolic pressure in the pulmonary artery, an increase in the cardiac volume, a decrease in the ejection fraction and left ventricular stroke work--changes which were most pronounced in AMI spreading, were noted in patients with AMI lingering forms. Signs of disseminated intravascular blood coagulation were noted in the venous and arterial blood of patients with lingering AMI forms. A high blood enzyme level was shown to be accompanied by a low level of antibodies to LDH and CPK.

The effect of a four-week experiment on ten fa/fa Zucker rats (aged seven weeks at the beginning) fed on a lipid-rich diet (HL: 31 per cent w/w lipids, 45.6 per cent starch) was compared to that of a control diet (C: 10 per cent lipids, 66 per cent starch) on control Fa/- rats using a special pair-feeding apparatus that made it possible to obtain an identical intake rhythm. Energy level of the intake was significantly higher for the HL diet than for the C diet. At the end of the experiment, fa/fa rats remained obese and hyperlipemic, and still showed liver steatosis. With equal energy levels ingested, the obesity of fa/fa rats was comparable for both diets; hypertriglyceridemia and hypercholesterolemia were identical for both diets. When compared to the C diet, the HL diet modified neither their obesity nor their hyperlipemia. Obese rat liver on the HL diet showed lower levels for triacylglycerols, cholesterol, GGT, ALT, LDH and aldolase activities, while hepatic glycerol kinase and AST activities were higher than and comparable to, respectively, the C diet. Thus the HL diet led to a decreased liver steatosis for fa/fa rats as compared to the C diet.

Authors present a girl without familiar antecedents of consanguinity with mild motor deficiency, hypotonicity and obesity during infancy, with progressive posterior healing. The girl did not present Marfan's habit or special phenotype, and had small hypertrophy of calfs. There was not recurrent respiratory infections. EMG was myopathic and muscle dependent seric enzymes (CPK, ALD, LDH...) were normal. Radiographically films showed increased relationship fat-muscle and pathology by MO and ME confirmed the presence of small sticks in muscle fibers. After evaluating the case as a neomutation, the genetic counseling is made.

A genetic variant of the spontaneously hypertensive rat (SHR) has been produced which becomes markedly obese as well as hypertensive, i.e. Obese/SHR weigh 800 g as against 300 g for non-obese cohorts. Serum enzymes (CPK, SGOT, SGPT and LDH) are frequently abnormally elevated, concomitantly with a high incidence of myocardial necrosis. Obese/SHR are hyperlipidaemic with severe fatty infiltration of the liver; they are hyperglycaemic with enormous islets of Langerhans and extensive beta-cell degranulation; despite elevated blood urea nitrogen (BUN) levels, they manifest little or no renal damage. Measurement of corticosterone, deoxycorticosterone (DOC) and aldosterone in Obese/SHR demonstrate marked hyper-responsiveness to moderate stress. Circulating prolactin levels are lower in Obese and non-obese/SHR compared to SHR, but Obese/SHR manifest unusually high increases incirculating prolactin levels in response to stress. Obese/SHR are hyperinsulinaemic and have subnormal growth-hormone levels. Desite mild hypertension, hyperglycaemia and hyperlipidaemia, Obese/SHR show no evidence of atheromatous change but do develop early polyarteritis nodosa. It is believed that the genetically programmed hypertension and hyperglycaemia is mediated by increased DOC, aldosterone and corticosterone production respectively, and that the obesity, hypertension, and diabetes in Obese/SHR may be likened to human Cushing's disease.

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.

The association of obesity and hypertestosteronaemia with elevated insulin concentration and dyslipidaemia was studied in 15 non-obese and 15 obese, hypertestosteronaemia patients; 14 non-obese and 10 obese, normotestosteronaemic subjects served as controls. Data were subjected to multivariate analysis. Enhanced body mass index (BMI kg/m2) resulted in a significant elevation of basal insulin (b-Ins), glucose-stimulated (delta) insulin (del-Ins), triglycerides (TG), very low density lipoprotein (VLDL), low density lipoprotein (LDL), and LDL/high density lipoprotein (HDL) ratio, and in a significant reduction of HDL. Furthermore, it was shown that BMI was positively correlated with TG, VLDL, LDL and LDH/HLD ratio, and negatively correlated with HDL in the normotestosteronaemic groups. Hypertestosteronaemia was associated with a significant increase of del-Ins, VLDL and LDL/HDL ratio, and with a significant decrease of HDL concentration. Testosterone was directly associated with del-Ins and LDL/HDL ratio, and inversely related to HDL in the non-obese groups. Summation effects of obesity and hypertestosteronaemia were found for del-Ins and VLDL. The data suggest that obesity and hypertestosteronaemia are independently and jointly associated with insulin resistance and dyslipidaemia, indicating an increased risk for coronary heart disease. The highest risk rate was found in obese hypertestosteronaemic patients. Serum testosterone may be a useful marker in detecting metabolic disorders connected with cardiovascular risk.

The mechanisms underlying the development of hypertension in obesity are not yet fully understood. We recently reported the development of hypertension in a rat model of diet-induced obesity. When Sprague-Dawley rats (n=60) are fed a moderately high fat diet (32 kcal% fat) for 10 to 16 weeks, approximately half of them develop obesity (obesity-prone [OP] group) and mild hypertension (158+/-3.4 mm Hg systolic pressure), whereas the other half (obesity-resistant [OR] group) maintains a body weight equivalent to that of a low fat control group and is normotensive (135.8+/-3.8 mm Hg). We examined the potential role of oxidative stress in the development of hypertension in this model. Lipid peroxides measured as thiobarbituric acid-reactive substances showed a significant increase in the LDL fraction of OP rats (2.8+/-0.32 nmol malondialdehyde/mg protein) compared with OR and control rats (0.9+/-0.3 nmol malondialdehyde/mg protein). Also, aortic and kidney thiobarbituric acid-reactive substances showed a significant (3- and 5- fold) increase in OP rats after 16 weeks of diet. In addition, superoxide generation by aortic rings, measured by lucigenin luminescence, showed a 2-fold increase in the OP group compared with both the OR and control groups. In addition, free isoprostane excretion and nitrotyrosine in the kidney showed an increase in OP rats only. The urine and plasma nitrate/nitrite measured by the LDH method showed a 1.8-fold decrease in OP rats compared with OR rats. However, endothelial NO synthase expression in the kidney cortex and medulla assessed by reverse transcriptase-polymerase chain reaction showed a strong increase in the OP rats versus OR and control rats (endothelial NO synthase/beta-actin ratio 1.3+/-0.04 in OP rats versus 0.44+/-0.02 in OR rats), suggesting a possible shift toward superoxide production by the enzyme. Collectively, the data show a decreased NO bioavailability in OP animals that is due in part to the increased oxidative stress.

Indications in cardiovascular and respiratory procedures, osteoporosis, Diabetes Mellitus and obesity and their specified actions with cardiorespiratory physical activity require parameters which are based on consumption of energy, on effort applied in the biomechanical kinetic activity and kinematics. Using three models of physical activity: 1. Aerobic resistance exercise; 2. Strength-Resistance; 3. Chronic overexertion. The results of neutrophils, proteinuria, LDH, CPK, GOT, GPT and blood iron levels correlate statistically with the results of trace minerals: Zinc and Copper.

Metabolite, insulin and adiponectin concentrations and LDH, AST and ALT activities were measured in plasma of 142 client-owned cats (1-13years old, 16 breeds) to set up a new criterion of hypertriglyceridemia (hyper-TG) with increased plasma insulin concentrations for early diagnosis of lipid metabolism abnormality including obesity. 25 cats with over 165mg/dl of plasma triglyceride (TG) concentrations were decided as hyper-TG with increased plasma insulin concentrations, and prevalence of hyper-TG was 16.7% in young (1-6years old) and 18.3% in old (>7years old) cats examined. In the hyper-TG cats, their plasma TG concentrations increased to 6.6-7.4-fold of the values of control cats with 35-50mg/dl of plasma TG and their plasma cholesterol, FFA and insulin concentrations and LDH and ALT activities increased significantly, whereas their plasma adiponectin concentrations decreased significantly compared to those in the control cats. Hyper-TG cats with significantly increased body weights and plasma insulin and decreased plasma adiponectin seemed to be in early stage of obesity accompanying increased plasma insulin concentrations. Increased TG, insulin, LDH and ALT and decreased adiponectin values in plasma seemed to be key factors for diagnosis of lipid metabolism abnormality at early stage in cats.
