摘要: Metabolic adverse effect is one of the most serious side effects associated with the use of atypical antipsychotics. Some investigators have suggested that some beneficial effects of high protein intake, such as preventing weight gain and promoting loss of body fat, might be attributed to the higher comsumption of branched-chain amino acids (BCAAs), like leucine (Leu). However, it is vague about the anti-obesity effect of leucine in animals treated with antipsychotics. Thus this study investigated the effects of leucine supplement on body weight and lipid metabolism in female C57BL/6JNarl mice treated by olanzapine (Olz). Mice were divided into four groups: olanzapine group (3 mg/kg/day), leucine supplement group (2%water/vol L-leucine), olanzapine combined leucine supplement group and control group. Seven-weeks treatments with olanzapine significantly increased body weight gain and hepatic triglycerides levels that compared to the control group (P < 0.05). However, there was no statistically different for body weight between olanzapine and olanzapine treated with leucine group. Western blotting analysis showed that the expression of FAS and SCD-1 (component of fat synthesis system) were not statistically different among all tested groups. These results suggest that olanzapine exerts some metabolic effects and this leads to increase the accumulation of body weight. However, leucine supplement was not observed to reverse obesity that induced by olanzapine in mice.
