Abstract: A kidney dialysis filter based on arginine attached to a cellulose polymer or a chitin polymer or a dendrimer polymer (or other nonsoluble carrier polymer—large enough that they will not go from dialysis machine to patient by going through the filtration membrane or by dissolving and entering the blood stream of the patient—or a non-biological oligomer), a kidney dialysis machine using the filter, and a method of producing the filter by, for example, attaching an arginyl grouping or moiety to a cellulose polymer or a chitin polymer or a dendrimer polymer (or other nonsoluble carrier polymer or a non-biological oligomer as mentioned above), can all be used to help prevent biological damage which might be caused by toxic carbonyl containing compounds and/or dicarbonyl containing compounds.

Abstract: A method of blocking dicarbonyls and carbonyls in vitro and in vivo includes using an effective quanity of an L- or D-arginine, substituted arginine, modified arginine or arginine-containing blocking agent. The method can, for example, include blocking toxic dicarbonyls and carbonyls in a patient suffering from a condition associated with toxic carbonyls and/or dicarbonyls, by administering to the patient a therapeutically effective dose of an L- or D-arginine, substituted arginine, modified arginine or arginine-containing blocking agent.
