[Latent ceruloplasmin activity in the frontal lobe of albino rat brains].

Latent ceruloplasmin activity was revealed in 5% of homogenates of the frontal lobes of the albino rats' brain. While assessing the activity of this enzyme in the investigated assays in the dynamics of their storage at 4-8 degrees C, the value under study continuously increased and on the 14th day of the experiment it reached 137% of the initial values. 1-Triphenylphosphoniomethylnafthalene bromide did not exert any effect on the dynamics of changes of ceruloplasmin activity in biological assays.
