Figure 1.

Effect of calcium and MuSK-MG plasma treatment (patient 1) on the contraction of regenerating FDB muscle (14 to 16 days after notexin). Plasma injections were started 1 day after notexin. Nerve stimulation with single pulses in muscles treated with patient’s plasma (squares) and control plasma (triangles). Direct stimulation of the same muscles with single pulses (open squares and triangles for patient and control, respectively). Means ± SEM of values from six to eight muscles. *P < 0.005; **P < 0.05 (Student’s t-test).
