Plasma Proteome Dynamics in the Pig Model of Trauma

The effect of IV-adminstered Vitamin C on the plasma proteome in the pig trauma model was investigated with label free proteomics. Plasma samples were drawn from 9 male Sinclair swine at baseline, post-trauma, and 0.25, 2, and 4 hourspost resuscitation with 500 mL of hydroxyethyl starch. Swine were randomized to receive either saline, low-dose VitC (50 mg/kg), or high-dose VitC (200 mg/kg) during volume resuscitation (N = 3/treatment). High performance LC-MS/MS proteomics was then used to quantitatively measure plasma protein fluctations over time as a function of treatment.
