Recently, glutamine and β-glucan have been demonstrated to play an important role in modulation of the immune system and in promoting intestinal health benefits. The aim of this study was to investigate the effect of this intervention on inflammatory responses and intestinal health in mice orally pretreated with soluble Saccharomyces cerevisiae derived 1,3/1,6-β-glucan (80mg/kg) with or without glutamine (150mg/kg) and then challenged with cytarabine (Ara-C) (15mg/kg). Improvements in villi and crypts were not observed in the β-glucan group. The intestinal morphometry in the glutamine group showed the best results. β-glucan in combination with glutamine presented the highest values of IL-1β and IL-10 and lowest values for leukocytes and INF-γ. Based on these results, combined β-glucan and glutamine pretreatment reduced intestinal inflammation and improved the immune response after Ara-C challenge. |
