||Abstract: "The dilution in the circulating blood of lymphocytes lablled in vitro with 3H-cytidine was examined after autotransfusion in 9 patients with Hodgkin's disease (HD) stage II A-IV B, 5 of whom were untreated in 2 untreated patients with carcinoma, and in 1 treated patient with scleroderma."
||P.213 bottom paragraph: "The mean life span of short-lived small blood lymphocytes was reported to be 4-7 days in rats and haematologically normal man [primary source 4, unpublished data] and 2.5-5.5 days in patients with Hodgkin’s disease [primary source 21]."
