Eight subjects with chronic intractable disease were subjected to intravenous
injections of India ink and the peripheral blood was studied for evidence of
phagocytosis. Carbon particles were seen not only in the granulocytes and
monocytes, but also in lymphocytes. Through these intravital studies, further
proof is established for the theory that human lymphocytes are capable of phagocytosis.
