The aldolase activities in the cerebral cortex of normal rabbits and rabbits with latent cerebral local anaphylaxis (LC LA) were measured by using Bruns' method, and influences of glutamic acid, glutamine, aspartic acid, asparagine, and γ-aminobutyric acid on the aldolase activities were evaluated. It has been experimentally probed that LCLA is an epileptic disposition and a state of arrangement of convulsion. The results were as follws. 1) The aldolase activity in the cerebral cortex of rabbits with LCLA is decreased, compared with that of normal rabbits. 2) Glutamic acid accelerates the activity of the cerebral aldolase of normal rabbits. 3) Asparagine accelerates the activity of the cerebral aldolase of LCLA rabbits.
