BACKGROUND In humans, ghrelin has been found to stimulate appetite while PYY3-36 to reduce it; these orexigenic and anorexigenic peptides play significant roles in appetite control. We investigated pre- and postprandial responses of ghrelin and PYY in anorexia nervosa (AN) and the influence of weight gain. METHODS Plasma ghrelin, PYY3-36, glucose and(More)
We investigated changes in regional cerebral blood flow (rCBF) before and after weight gain in patients with restrictive anorexia nervosa (AN-R) in comparison with findings in normal subjects. We assessed resting rCBF using single photon emission computed tomography with technetium-99m hexamethylpropylene amine oxime in 12 AN-R patients and 11 controls.(More)
OBJECTIVE In recent years great advances have been made in our understanding of the peripheral signals produced within the gastrointestinal tract that regulate appetite, such as ghrelin and peptide YY (PYY). While ghrelin elicites hunger signals, PYY elicites satiety. Therefore, alterations in hormone physiology may play a role in the pathogenesis of(More)
OBJECTIVE Fasting plasma ghrelin levels play an important role in the pathophysiology of the eating disorder anorexia nervosa. Bulimia nervosa (BN) also has been associated with abnormal neuroendocrine regulation. Thus, we examined the relationship between body mass index (BMI) and plasma ghrelin concentrations in patients with BN for the first time. (More)
Circulating ghrelin and growth hormone (GH) are up-regulated in anorexia nervosa (AN) as a consequence of prolonged starvation. The current study examines the effect of nutritional rehabilitation with improvement of eating behavior on ghrelin and GH levels in AN patients during the course of inpatient treatment. The subjects included 34 female AN patients(More)
OBJECTIVE Ghrelin is thought to be involved in the regulation of eating behaviour and energy metabolism in acute and chronic feeding states. Circulating plasma ghrelin levels in healthy humans have been found to decrease significantly after oral glucose administration. Because it is suggested that eating behaviour may influence the secretion of ghrelin and(More)
OBJECTIVE Osteoporosis is recognized as a common medical complication of anorexia nervosa (AN). The purpose of the current study was to investigate the recovery mechanism of osteoporosis in AN and the effect of medical treatment on the skeletal system. METHOD We conducted a randomized placebo-controlled study of the effects of etidronate and calcium and(More)
BACKGROUND & AIMS The aim of this study was to determine the relationship between insulinogenic index at 15 min (II15 min), body weight maintenance, and the presence of vomiting in patients with bulimia nervosa. METHODS Forty-eight bulimic inpatients and 14 controls underwent an oral glucose tolerance test on the seventh hospital day. We calculated II15(More)
Patients with bulimia nervosa (BN) have bulimic and depressive symptoms, which have been associated with abnormalities in the neuroendocrine and vagal systems. Subjects included twenty-four female drug-free outpatients with BN that were selected from patients seeking treatment for eating behavior in our hospital along with twenty-five age-matched healthy(More)
We present a hypermedia-based conversation recording method to preserve informal artifacts which are obtained in a realtime collaboration. Informal artifacts are not final goals but important results such as a process of a decision, an individual opinion, a rejected idea, or a nuance. Conversation in a realtime collaborative session is recorded linked with(More)
