[Comparison of proliferative and immunoglobulin-secreting capacity of peripheral blood lymphocytes of healthy persons and patients with B-cell immunoproliferative diseases].
The proliferative response and in vitro immunoglobulin production induced polyclonal activators were studied in 12 patients with multiple myeloma (MM) and in 15 healthy individuals. The spontaneous production of IgM was decreased. PWM-induced immunoglobulin production of the peripheral blood lymphocytes was the same.
