[Effect of glutamine on apoptosis of the small intestine in young rats with endotoxemia and its mechanism].

Objective: To study the effect of glutamine on intestinal epithelial apoptosis by examining changes regarding Bcl-2 and Bax mRNA expressions in the small intestine of young rats with endotoxemia and to explore the protective mechanism that glutamine may have.

Methods: A total of 120 18-day-old rats were randomly assigned into Endotoxemia, Glutamine-treated and Control groups (n = 40 each). The endotoxemia model was established by intraperitoneal injection of endotoxin (4 mg/kg of O55B5 Escherichia coli lipopolysaccharide).
