Differential effects of heat in the phases of the light-dark cycle in the activity-based anorexia model.

摘要: Background: This research builds on the studies ambient temperature as a key influence in recovery of rodents exposed to activity-based anorexia (ABA) model. The ABA model is an experimental paradigm which under restricted feeding schedule and with free access activity wheel show signs that parallel those nervosa humans. Objective: present study focuses effects applying heat during different phases dark–light cycle levels, body weight, food intake, temperature, rates 30 male rats submitted ABA. Method: After reaching 20% weight loss criterion, animals were randomly assigned three conditions: (a) continuous warming, (b) warming exclusively light phase, or (c) dark phase. Results: Differential found depending modalities warming: comparison either significatively decreased activity, facilitated gain, maintained temperature. Transient both groups warmed periods exclusively. Discussion: results suggest did not promote Evidence about beneficial are line previous reinforces adding external useful tool treatment nervosa.
