[Phosphatase activity in the lymph during a fever reaction]

Activity of acid and alkaline phosphatases, as well as isoenzymes of alkaline phosphatase in the lymph of the thoracic lymphatic duct, hepatic lymph and the peripheral blood have been studied on rabbits in the dynamics of the fever reaction of different duration. The fever reaction was followed by enzyme activity increase in all the body biologic fluids. However the degree of increase of their activity in the lymph was greater that that in the blood. Our data indicate that in the transport of phosphatases released from the tissues in the common circulation the essential role is played by the lymphatic system, the resorption and transport functions of which significantly characterise the dynamics and the level of their changes in the blood in fever reaction.
