Accumulation of activated lymphocytes in liver of endotoxin treated rabbits.

Intravenous administration of endotoxin in doses, 1.0 mg/kg, 0.1 mg/kg or 0.01 mg/kg caused activation (in the sense of nucleolar RNA synthesis) of the lymphocytes in peripheral blood, kidney and liver in rabbits. The evaluation of the ratio of lymphocyte count to the number of organ tissue cells leads to the conclusion that the accumulation of endotoxin activated lymphocytes occurs in liver.
