[Mononuclear peripheral blood cells in patients with non-Hodgkin's lymphoma synthesizing DNA in vitro].
In 82 patients with non-Hodgkin lymphoma (NHC) the DNA synthesis by mononuclear cells from the peripheral blood was assessed by means of the index of mitoses (IM) or by pulse labelling of cells with 3H-TdR. In chronic lymphatic leukaemia (47 cases), hairy-cell leukemia (1 case), plasma-cell leukaemia (1 case) no synthesis of DNA was found in mononuclear cells. On the other hand, it was raised in most cases of lymphoplasmocytoma, centrocytoma, centroblasto-centrocytoma, centroblastoma and in lymphoblastic leukaemia or lymphoma.
