2. Fig. 1
Individual plasma vitamin C concentrations before, during, and after CPB. A, Control subjects. B, Subjects receiving supplemental vitamin E. Each symbol represents one subject. The dashed lines represent thresholds for marginal deficiency(<0.4 mg/dl) and "scorbutic" levels (<0.2 mg/dl), respectively.

3. Fig. 2
Decrease of mean values of plasma vitamin C, creatinine, urea, and uric acid during and after CPB. Values are relative, in comparison with the baseline values on the right (means ± standard deviation of absolute baseline values on the right = 100%). A, Control subjects. B, Subjects receiving supplemental vitamin E.

5. Fig. 3
Plasma vitamin E concentration before, during, and after CPB. Open symbols are unadjusted values (means ± standard error of the mean) and closed symbols are lipid-standardized concentrations. Squares indicate patients receiving supplemental vitamin E, and circlesindicate control subjects.

6. Fig. 4
CPB-related time course of plasma concentrations (means ± standard deviation) of lipid-soluble essential antioxidants and of cholesterol. The values are not lipid-standardized. Values are relative, in comparison with the baseline values on the right (=100%). A, Control subjects. B, Subjects receiving supplemental vitamin E.
