Abstract
Abstract Pharmaceutical preparations containing reaction products of riboflavin and/or ribose with formaldehyde or compounds yielding formaldehyde such as paraformaldehyde are useful therapeutic agents for the treatment of disorders of the cell metabolism and for normalizing improperly functioning cells such as, degenerative diseases due to radiation and to malfunction of the nervous system.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
41 words
THE REACTION PRODUCT OBTAINED BY POLYCONDENSATION AND POLYMERIZATION OF THE REACTION MIXTURE COMPOSED OF AN AQUEOUS SOLUTION OF FORMALDEHYDE, A PNETOSE COMPOUND SELECTED FROM THE GROUP CONSISTING OF RIBOSE AND RIBOFLAVIN, AN INORGANIC SALT, AND A COMPOUND CONTAINING AN AMINO GROUP.
Claim 2
Dependent Claim
41 words
THE REACTION PRODUCT OBTAINED BY POLYCONDENSATION AND POLYMERIZATION OF THE REACTION MIXTURE COMPOSED OF AN AQUEOUS SOLUTION OF FORMALDEHYDE, A PNETOSE COMPOUND SELECTED FROM THE GROUP CONSISTING OF RIBOSE AND RIBOFLAVIN, AN INORGANIC SALT, AND A COMPOUND CONTAINING AN AMINO GROUP.
Claim 3
Dependent Claim
36 words
In a process of producing the reaction product of claim 1, wherein the reaction product is irradiated with ultraviolet light, cooled at a temperature of about -20* C., and heated to a temperature of 300* C.
Claim 4
Dependent Claim
40 words
The reaction product resulting from the fusion of polymerized formaldehyde with a polymerized pentose selected from the group consisting of ribose and riboflavin, said fused reaction product containing at least two methylene groups in its molecule joined by oxygen linkage.
Claim 5
Dependent Claim
40 words
The reaction product resulting from the fusion of polymerized formaldehyde with a polymerized pentose selected from the group consisting of ribose and riboflavin, said fused reaction product containing at least two methylene groups in its molecule joined by oxygen linkage.
Claim 6
Dependent Claim
34 words
In a process of producing the reaction products of claim 2 by polymerization under the influence of heat and light in the presence of a peroxide catalyst with free photochemical dissociation of the catalyst.
