In the first 6 days following brain surgery, commNTS lesioned rats reduced daily food intake by 80% compared to rats with sham lesions. After this period rats with lesions of commNTS started recovering food intake, but intake remained significantly reduced until the 12th day after surgery. A reduction in body weight was observed 4 days after surgery and reached a maximum on the 12th day. After this, a partial recovery of body weight was observed, but weight remained significantly reduced compared to weights of rats with sham lesions through the conclusion of the study. Food intake and body weight gain in other rats with partial lesions of the commNTS or with lesions outside the commNTS did not differ from rats with sham lesions with regard to those variables. Daily water intake and plasma glucose and insulin were not changed by the commNTS lesions. These results suggest that commNTS is involved with mechanisms that control food intake and body weight in rats.102-108engfood ingestionglucosehindbraininsulinsatietywater intakeanimal experimentanimal tissuebody weightbrain injurycontrolled studyfluid intakefood intakehistologypriority journalsolitary tract nucleusNon-programmaticBody WeightDrinkingEatingRatsRats, Sprague-DawleySolitary NucleusArtigo10.1016/S0006-8993(96)00850-5WOS:A1996VX99400013Acesso restrito2-s2.0-003059275210235978701181054544450092427426
