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)
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)
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)
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)
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 Little is known about biologic predictors of refeeding outcome in anorexia nervosa (AN). Because nutritional status mirrors glucose metabolism during an oral glucose tolerance test (OGTT) in AN, this study investigated whether pretreatment glucose response patterns during the OGTT might be associated with refeeding progress in patients with AN.

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)
