Claim One:
1. A method of obtaining a composition adapted for use by injection into the animal organism for topical action upon the animal brain to produce synthesis of brain components involved in the learning process, comprising deoxyribonucleic acid which contains 5 Hydroxymethylcytosine, with substantial inhibiting of enzymes and chemical degradents, said method comprising the steps of homogenizing an animal brain in a solution of sodium bromide, potassium citrate, sodium arsenite, sodium deoxycholate and glutathione, precipitating DNA with alcohol, transferring the resultant precipitate to the aforesaid solution form but omitting the sodium bromide and subjecting said precipitate to further homogenizing, followed by the consecutive additional steps, namely: a. Transferring the said precipitated solids thus treated to a solution which is the same as that first stated but omitting the sodium bromide and the sodium deoxycholate and reducing concentration of glutathione; and stirring the solution in the presence of an active precipitant and thereby forming a white precipitant b. The white precipitant is dissolved in a solution of the same form as that stated in (a) together with lysozyme the latter having been purified by a water bath. c. The white precipitate of deoxyribonucleic acid and lysozyme in its solvent is stirred, centrifuged, and the supernatent solution is discarded and the precipitated solids are washed with a solution composition as in (a) above and then dissolved in a solution the same as that stated above for hydrogenation but with lower sodium bromide concentration and precipitated with alcohol and by such action is formed a white precipitate of deoxyribonucleic acid, while the lysozyme is discarded; the precipitate then is transferred to a solution which is identical to that used after the last named homogenation step, dissolved and further purified by treatment with chloroform-isomethyl alcohol mixture; then the solution of deoxyribonucleic acid is precipitated with alcohol, dissolved in dilute citrate, physiological sodium chloridr- chloride - 0.14M, and dilute glutathione. Finally the composition is precipitated with alcohol from said solution.
