As a complex syndrome, cachexia has different clinical manifestations; anorexia appears to be one of the most frequent findings, together with weight loss. Anorexia is the cause and partly the consequence of metabolic changes and of progressive undernourishment. In cancer cachexia, weight loss is associated with a marked decrease of ...
Tuomisto J T - - 1995
Long-term regulation of body weight and food intake were studied after rats were subjected to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), which causes hypophagia and body weight loss, and to ventromedial hypothalamic lesion, which causes hyperphagia, metabolic changes and obesity. These two factors appeared to have an interaction, as ventromedial hypothalamic lesion initially aggravated ...

Anorexia nervosa (AN) is associated with a paradoxical reduction in hunger ratings following 2-deoxy-D-glucose (2DG) induced glucose insufficiency. Because of the relationship between exercise and AN, there is interest in the weight-loss phenomenon produced by exercise in food restricted rats. This investigation determined if the weight-loss phenomenon is associated with ...

Interleukin-1 (IL-1) is a cytokine which is released during immune activation and mediates some of the host's responses to infection and inflammation. Increasing evidence suggests that it also has a role as an intrinsic neuromodulator in the central nervous system. We report here that microinjections of 5 and 30 ng ...
Rieg T S - - 1994
It has been proposed that anorexia nervosa (AN) is treatable with serotonergic (5-HT) agonists. It seems paradoxical to treat a disorder characterized by reduced food intake with appetite suppressants. The effects of the indirect-acting 5-HT agonist D-fenfluramine on activity-based anorexia (ABA) were investigated, coincident with ABA (experiment 1), and after ...
