Figure 8. Time dependence of CMF amplitude following exposure to adrenaline in the absence and presence of IBMX.

RBCs were incubated with 10−7 M adrenaline in the absence (•) and presence (○) of 10−3 M IBMX (for different time periods) at 37 °C. The amplitudes are given by δImax/I (%; means ±s.e.m.) Each independent experiment involved measurements of 15-25 RBCs.
