Effects of guanethidine sympathectomy on feeding, drinking, weight gain and amphetamine anorexia in the rat Academic Article uri icon


  • Adult female rats that underwent sympathectomy induced by guanethidine treatment (10, 20 or 40 mg/kg) exhibited markedly increased water intake, but did not display significant alterations of either food intake, body weight, or the Lee Index of obesity. Guanethidine treatment did not attenuate amphetamine anorexia as evidenced by comparable dose-dependent reductions in food intake to d-amphetamine sulfate (0.25, 0.50, 1.0, and 2.0 mg/kg) in sympathectomized and control rats. These data are not consistent with the hypothesis that amphetamine anorexia is partially mediated via enhanced BAT thermogenesis.
