Abstract

Abstract: SPF grade Balb/c female mice were used as experimental animals. After adaptive feeding for 3 days, mice were orally pre-treated with different dosages of L-theanine once daily for 30 days before ETEC E44813 intraperitoneal injection. The body weight change in mice was analyzed during the breeding process. Mice were scarified 5 hours after ETEC injection and tissues were collected for analysis. The activities of ileum Glutathione peroxidase (GSH-Px), homogenate Catalase (CAT), Malondialdehyde (MDA) and Inducible nitric oxide synthase (iNOS) were measured and the pathological changes of intestinal and the levels of serum Tumor necrosis factor-α (TNF-α), Interleukin-1β (IL-1β) and Intercellular cell adhesion molecule-1(ICAM-1) were examined. This study was
