bordered on significanceP = .061
In terms of cell hydration, we observed slight dehydration in RBCs stressed by H 2 O 2 bordered on significance (347 mOsm/kg for 0 μM H 2 O 2 vs 340 mOsm/kg for 50 μM H 2 O 2 ; P = .061), but more interestingly, we found that Gln supplementation significantly improved hydration status compared with RBCs not supplemented with Gln (340 mOsm/kg for 0 μM Gln vs 344 mOsm/kg for 1000 μM Gln; P = .031) ( Figure 1 D).
