Figure 4

Grey bars indicate period of infusion. Values are mean ±s.e.m. of 9 dogs studied in four protocols. For protocols and periods see legend to Fig. 1. Significant differences: * significant versus fRPP, † significant versus fRPP + E, ‡ significant versus scRPP; within each protocol, PRA was lower in I5 and P2 as compared with control periods; in scRPP, PAC was lower in I5 and P2 as compared with control periods.
