obsesive

Schizophrenia and obsesive compulsive disorder (OCD) are among the oldest described psychiatric disorders. Although they appear to be two distinct psychiatric disorders, early literature about the existence of obsessive-compulsive symptoms in schizophrenia dates back to the 1920's. The findings that atypical antipsychotics exacerbate obsessive-compulsive symptoms among schizophrenic patients and the emergence of a possible biological relation between the two diseases increased interest in this subject. Until the 1990's information about the aetiology of obsessive-compulsive symptoms which are observed in about 60% of schizophrenic patients, was insufficient...

OBJECTIVES: (1) To determine the prevalence of abnormal liver enzymes in overweight and obese adolescents and (2) to determine the relationship of alcohol ingestion and serum antioxidants to the presence of abnormal liver enzymes in overweight and obese adolescents. METHODS: Serum alanine aminotransferase (ALT) and gamma-glutamyl transpeptidase levels were measured in 2450 children between the ages of 12 and 18 years, enrolled in the National Health and Examination Survey, cycle III (NHANES III)...

Rats with lesions to the ventromedial hypothalamus (VMH) manifest obesity, hyperphagia, and hyperinsulinemia, and fetal VMH transplantation into the third cerebroventricle of VMH-lesioned rats reduces the development of obesity caused by the lesion. The aim of this study was to determine whether the hyperphagia, hyperlipidemia, and hyperinsulinemia of obsese Zucker rats could be corrected by the transplantation of lean fetal Zucker hypothalamic tissue into the third cerebral ventricle of Zucker obese rats. After the fetal hypothalamic transplant (obese-HY), the rate of weight gain was significantly diminished compared with the unoperated Zucker obese rats and the obese rats that received the transplantation of a similar amount of frontal cortical tissue from the same fetus (obese-FC)...

The development of vitamin B1 (thiamine) deficiency was investigated in 17 obese patients in the course of a 1000 calory diet or during total fasting for a fortnight. Compared with normal persons no changes of concentrations of total thiamine, TPP, and pyruvate in the blood; thiamine excretion in the urine, or activiation coefficient of the eryhrocyte transketolase (alphaETK) were observed during the reducing diet. However, during a fortnight's total fasting all values decreased significantly to those of thiamine deficiency...

Two hyperinsulinemic rhesus monkeys, made obsese (body weight 22 kg) by the placement of hypothalamic lesions, were place on a weight reduction diet for a period of approximately eight months. After losing approximately losing approximately 25% body weight, the animals exhibited a fall in serum insulin levels without changes in plasma glucose levels or composition of fat pad tissue. There was evidence that the number of adipocytes remained constant but were reduced in size after the body weight loss.

Total testosterone, the fraction of unbound testosterone and free testosterone were measured in 116 males of varying body weight in the range of 80 to 256% of the ideal weight. There are 3 groups for the establishment of normal ranges of testosterone. Testosterone and the fraction of unbound testosterone were fairly constant in group I (80--160% of the ideal weight). In group II (160--200% of ideal weight) there was a tendency towards lower values. The relatively wide normal range for testosterone was not reached in only 5 of these 20 patients...

A clinical and laboratory examination of abnormalities not attributable to atherosclerosis has been performed on 188 male and 126 female adult subjects with hyperlipidaemia. The sample was recruited from 20000 subjects screened at a health control centre who had an initial serum cholesterol and/or triglyceride (TG) concentration above 350 mg/100 ml and 3.50 mmol/l. All were subjectively healthy and had no history of atherosclerotic disease. Known cases of secondary hyperlipidaemia were excluded. Lipoprotein (LP) analysis with preparative ultracentrifugation and electrophoresis was made on all subjects including control group with "nonelevated" serum lipids...
