ABSTRACT
Botryosphaeran is an exocellular (1 → 3)(1 → 6)-β-d-glucan that promotes significant metabolic effects in male rats, as antiobesogenic and hypoglycemic effects. This study aimed to investigate its metabolic effects in female Wistar rats subjected to a high-fat high-sucrose diet. Obesity induction resulted in increased body weight, accumulation of adipose tissue, glucose intolerance, insulin resistance, hepatomegaly and high levels of TBARS (oxidative stress marker) in the liver, compared with the controls; all differences were statistically significant (p ˂0.05). Treatment with botryosphaeran (12 mg/kg/day; 15 days) significantly reduced the weight gain (p ˂0.01), the retroperitoneal adipose tissue (-29.7%, p ˂0.05), and corrected glucose intolerance with a 8.32% reduction in the area under the curve (AUC, p ˂0.05), relative to untreated obese rats. Furthermore, botryosphaeran reduced the levels of TBARS (-45.4%, p ˂0.05) in liver, reducing oxidative stress. Additionally, no differences were observed in the liver for protein carbonyls, superoxide dismutase, catalase, glutathione peroxidase, and ascorbic acid. In conclusion, botryosphaeran was observed to promote a significant antiobesogenic effect, promoting an expressive loss in body-weight, reduction of adipose tissue, correction of glucose intolerance and promoting an antioxidant effect in the female rats.
