Fig. 2. Lack of synergism between Tenmo-DH₃₇ (DH37) and Tenmo-DH₄₇ (DH47). Diuretic peptides were tested at 0.2 nmol l^–1 and 40 nmol l^–1, approximately 1.5 times their respective EC₅₀ values, after which the Ringer’s solution was changed to one containing both peptides (at these same concentrations). No change in secretion rates was observed. Data are presented as means + 1 S.E.M. (N=8).
