Effects of glutamine-containing total parenteral nutrition on phagocytic activity and anabolic hormone response in rats undergoing gastrectomy

Figure 1 Body weights of experimental groups at the beginning of TPN administration and before sacrifice.

Figure 2 Plasma glutamine (Gln) levels of the 2 groups before and after surgery. ^aP<0.05 vs control group on post-1d.

Figure 3 Nitrogen balance and cumulative nitrogen balance between the 2 groups after operation. ^aP<0.05 vs control group on post-operative days. A: Nitrogen balance between the 2 groups after operation; B: Cumulative nitrogen balance between the 2 groups after operation.

Figure 4 Plasma growth hormone (GH) and insulin-like growth factor-I (IGF-I) concentrations between the 2 groups before and after operation. ^aP<0.05 vs the corresponding group on post-operative days. A: Plasma growth hormone concentrations between the 2 groups before and after operation; B: Plasma insulin-like growth factor-1 concentrations between the 2 groups before and after operation.

Figure 5 Phagocytic activity of peritoneal macrophages and peripheral blood neutrophils. A: Phagocytic activity of peritoneal macrophages measured by phagocytosis assay and read in the fluorescence plate reader using 480 nm for excitation and 520 nm for emission. ^aP<0.05 vs control group on post-1d; B: Peripheral blood neutrophils measured by flow cytometry; ^cP<0.05 vs the corresponding groups on post-operative days.
