Abstract:

In this study,the experiment was conducted to investigate the effects of beta-1,3/1,6-glucan on anti-oxidative functions of Caco-2 cells infected by Salmonella enteritidis.In the experiment,Caco-2 cell line was used as an in vitro model.Caco-2 cells were treated by MEM(group A),beta-1,3/1,6-glucan(group B),Salmonella enteritidis(group C),respectively;Caco-2 cells in group D were pre-incubated with β-1,3/1,6-glucan and then infected with SE.The results showed that the T-AOC concentration significantly increased in group C at 3 and 12 h in cell culture supernatant(P<0.05).Compared with the control group,the MDA concentration decreased after Caco-2 cells treated 3 h,while enhanced at 12 h(P<0.01) in cell culture supernatant in group C.Pre-treated with beta-1,3/1,6-glucan increased significantly the total antioxidative capacity of T-AOC in cultured supernatant of Caco-2 cells at 12 h(P<0.01)and had the tendency to decrease the MDA concentration and increase the SOD activity in cultured supernatant.And the GSH concentration decreased in group D in cell lysate at 12 h.These results suggested that beta-1,3/1,6-glucan can enhance the anti-oxidative function of Caco-2 cells challenged with SE by increasing the T-AOC activity and cutting down the MDA concentration.
