(A) Dose–response curves for Dippu-DH₃₁, Dippu-DH₄₆, and chicken calcitonin with Mt of D. punctata. Fluid secretion was measured without and with hormone, and the percentage stimulation was determined. (B) Dose–response curve for diuretic activities of Dippu-DH₃₁ and -DH₄₆ with Mt of L. migratoria. Data points are the means and vertical lines the SEM of five to seven determinations. The data are expressed as percentages of the response to 50 nM Locmi-DH. All were fitted by nonlinear regression analysis by using prism 2.0b.
