APS: Astragalus Polysaccharides
Control: normal saline; Lectin group: 12.5 mg/kg/bw red kidney bean lectin; APS group: 100 mg/kg/bw APS; Low dose group: 12.5 mg/kg/bw lectin + 25 mg/kg/bw APS; Moderate dose group: 12.5 mg/kg/bw lectin + 50 mg/kg/bw APS; High dose group: 12.5 mg/kg/bw lectin + 100 mg/kg/bw APS. Data were analyzed by one-way analysis of variance. ^∗𝑃<.05, ∗∗𝑃<.01, compared with the control group.
