[Cytophotometric study of the DNA in the lymphocytes from human lymph nodes in culture].

In the suspension culture of lymph node cells taken from patients with exzemic erythroderma, an active blast-transformation of lymphocytes starts in 24 hours, whereas in patients with mycosis fungoides this begins only in 48 hours. In lymphocytes taken from patients with mycosis fungoides, a tendency to a slower increase in DNA quantity was noticed compared to that in patients with exzemic erythrodermy. The differences observed may be used for diagnostic purposes.
