[Effect of early enteral feeding on the expression of aquaporin 1 in edematous small intestinal tissues of rats after severe burn].

Objective: To investigate the changes in the expression of aquaporin 1 (AQP-1) in edematous small intestinal tissues of rats after severe burn and the effect of early enteral feeding on its expression.

Methods: Ninety normal adult Wistar rats were randomly divided into normal control group (n=6), burn model group (n=42, with 30% TBSA III degrees) and early feeding group (n=42). Dry weight method, ELSIA and immunohistochemistry were used to observe and detect the water content and expression of AQP-1 in the intestinal tissue at 1, 4, 8, 12, 24, 48, and 72 h after the burns.
