Absolute plasma antioxidant concentrations in non-pancreatic surgical patients at baseline and after receiving control-PN or Gln-PN for 7 days. Plasma concentrations of Vitamin C, α-tocopherol, zinc and GSH were similar between the two study groups at baseline and day 7. However, compared with baseline (day 0) values, α-tocopherol levels were significantly improved with control-PN at 7 days (* p<0.04, day 0 versus day 7) and zinc levels were significantly improved with Gln-PN (*p<0.002, day 0 versus day 7). No differences in absolute plasma vitamin C or GSH values occurred from baseline to day 7 in either PN group.
