MW (SC = 0.1–0.5) (a–e) and percent change (after/before) of the MW (0.1–0.5) after the 24-h CHF experiments (f–j). Data are expressed as the mean ± SD, n = 3, * indicates p < 0.05. The reduction in the MW of dextran after blood contact did not differ between the PS and NV-PS for small dextran molecules, but for large dextran molecules with an SC of ≦ 0.4, the MW (SC = 0.1–0.4) of the NV-PS were lower than those for the NV-PS (SC = 0.1: p = 0.0423; SC = 0.2: p = 0.0437; SC = 0.3: p = 0.0206; SC = 0.4: p = 0.0037, paired t-tests)
