6. Figure 5
Effect of Fab fragment directed against digitalis (D) on the uremic extract pooled from 4 of the 5 patients (UE, 10%) inhibition of 86Rb uptake in LLCPK-1 cells. Each data point was derived from N = 3 experiments. D is Fab fragment alone (10, 20 and 40 μL data pooled). Final reaction volume was approximately 1mL. *P < 0.05 and **P < 0.01 vs. UE alone. D alone not compared with UE alone.

7. Figure 6
Effect of Fab fragment (D) on uremic extract (UE 3.5%) effects on myocyte contraction, relaxation and calcium cycling. Data are presented as percent change from baseline after 5 minutes following addition of UE alone or UE mixed with D. Each data point was obtained from N = 4 replicants. Symbols are: (□) fractional shortening; () diastolic [Ca]; () systolic [Ca]; () τ edge; () τ calcium. *P < 0.05 and **P < 0.01 vs UE alone.
