Expression of occludin (A) and JAM1 (B) proteins was examined by Western immunoblots. Results are expressed as the ratio of the tight junctional protein expression to the β-actin protein expression. The expression of occludin and JAM1 were significantly decreased with total parenteral nutrition (TPN) administration compared with controls. With glutamine (GLN) administration, the expression of these proteins increased, and levels of expression were not significantly different from control levels (*P < 0.05; #P > 0.05).
