Cell count of MC. HMC was incubated in 0·5%FCS culture medium alone (0·5%FCS) or with 100 µg/ml of normal aIgA1 (Nor.aIgA1) or patients’ aIgA1 (Pat.aIgA1) for different hours before count. The cell was a mixture of six lines and the aIgA1 sample was from pooled sera of 10 healthy controls or 10 patients. Results shown were means of three different experiments with triplicate wells. *P ≤ 0·05, Nor.aIgA1 versus 0·5%FCS; **P ≤ 0·05, Pat.aIgA1 versus 0·5%FCS or Nor.aIgA1; #P ≤ 0·05, 48 h versus 24 h or 72 h versus 48 h in the same group.
