Regulation of N-Acetyl-D-glucosamine on macrophages function of stressed mice / 第三军医大学学报

ABSTRACT

Objective To investigate the regulative role of N-Acetyl-D-glucosamine(GlcNAc) on the stressed mice macrophages function.Methods The stressed mice model was established by electric footshock method.The mice were divided into 5 groups:normal control group,stressed mice model group,low dose Glc-NAc treatment group(0.25 ml 15% GlcNAc),medium-dose GlcNAc treatment group(0.5 ml 15% GlcNAc) and high-dose GlcNAc treatment group(1 ml 15% GlcNAc).GlcNAc was intragastrically injected to corresponding mice 2 h before the electrical stimulation.Peritoneal macrophage(PM?) phagocytosis capability was detected by phagocytosis saccharomycete assay,and PM? energy metabolism was detected by MTT assay.Results Compared with normal control group,stressed mice PM? phagocytosis capability was significantly lower(P
