3. Fig. 2
Responses to carbachol in the presence of Ig fraction from patients or healthy controls. Ig from a patient with scleroderma significantly inhibits carbachol-evoked responses at concentrations of (A) 0.3 mg/mL (P = ) and (B) 1 mg/mL (P < ). (C) IgG from a healthy control does not significantly alter carbachol-evoked responses (P > 0.05). (D) The maximum percentage inhibition of contractions evoked by 30 μmol/L carbachol with increasing concentrations of IgG from antibody-positive patients (n = 10) and healthy controls (n = 4) occurred at a concentration of 0.6 mg/mL.
