    Abstract

    AIM: To determine the effect of glutamine (Gln) on Toll-like receptor (TLR) 2 and 4 expression in rats with intestinal endotoxemia.

    METHODS: Twenty-four Wistar rat pups aged 10 d were randomly divided into three groups: control (normal saline 1 mL/kg ip, n = 8), lipopolysaccharide (LPS) (LPS 5 mg/kg ip, n = 8), and Gln group (LPS 5 mg/kg + Gln 10 mL/kg ip, n = 8). The rats were sacrificed at 3 h after treatment. The small intestine was dissected for histological analysis, and expression of TLR2 and TLR4 mRNA was detected by reverse transcription-polymerase chain reaction. TLR2 and TLR4 protein expression was measured by Western blotting. ......
