[Cytological composition of lymph in fever reaction].

This work deals with an investigation into the lymph cytologic composition of thoracic lymph duct of rabbits in fever reaction (FR) of various duration. FR was accompanied by quantitative and qualitative shifts in lymph cytologic composition. There was an alternative rise and fall of the leucocyte number in the first hours of fever. The number of little and medium leucocytes decreased while the number of eosinophiles, insufficiently differentiated cells-blasts, large lymphocytes, prolymphocytes increased. Our investigations revealed a significant role played by the lymphatic system in lymphoid cells mobilization in FR, which is evident by a considerable lymphocyte number gaining entrance to the blood through thoracic duct.
