Figure 1. Dependence of CMF amplitude on adrenaline concentration at 24 and 37 °C.

RBCs were incubated with adrenaline for 30 min at 24 °C (○) and 37 °C (•). Data are given in terms of the time-averaged maximal peak-to-peak amplitude of CMFs in the frequency range 0.3-35 Hz. The amplitudes are given by δImax/I (%; means ±s.e.m.); see Methods. Each independent experiment involved measurements of 15-25 RBCs.
