Pharmaceutical preparation for the treatment and follow-up care of tumors that comprises the blood plasma or predetermined blood plasma components of equidae animals with pair number of fingers, preferably cattle being not endangered lethally by leucosis. The predetermined fraction is the material bovin 40 and/or bovin 300 constituting the difference detectable by electrophoresis between the lipid-free fraction taken from a cattle having leucosis an the lipid-free fraction taken from a healthy cattle. In the separation method of the required fraction the initial blood is optionally treated by an anti-coagulant and the corpuscles are separated therefrom, the plasma fraction is treated by a first organic solvent, then a surfactant material composed of fine grains is added thereto, the liquid is mixed and the lipid-free fraction bound to the grains is separated from the liquid components by centrifugation, and the separated fraction is brought again into a solution.
