Fig. 8. Effect of storage and CR AgNPs on HRBCs, Rb⁺ influx, and [K]_i from different donors. RBCs obtained from adult donors at DCBC or cord blood from MVH were subjected to the procedures described in Materials and Methods. During the flux period, cells were incubated at 37 °C for 60 min under the conditions described in the legend to Fig. 3. Rb⁺ influx and [K]_i were determined as described in Materials and Methods. Values are means± S.D. Details are discussed in the text. E, F, CB represent RBCs from expired or fresh adult donors, and cord blood, respectively, whereas D represents days in storage at 4 ^o C. Each bar corresponds to different patients for CONTC, CONT, and NPS.
