Figure 5. Effect of isoproterenol on CMF amplitudes in oxygenated and deoxygenated RBCs.

RBCs were incubated in the absence (Control; □) and presence (
) of 10−9 M isoproterenol for 20 min, at 37 °C. The amplitudes are given by δImax/I (%; means ±s.e.m.), where n (given in parentheses) is the number of RBCs tested.
