Retardation of calcium oxalate precipitation by glutamic-oxalacetic-transaminase activity.

It has been found that calcium oxalate stone formers have low UGOT activity compared to healthy individuals (controls). Urine from stone formers with no GOT activity and no effect on calcium oxalate precipitation was incubated with GOT for various periods. Subsequently calcium oxalate precipitation was decreased and found to be considerably retarded i.e., the pathological urine after the incubation acted in a way similar to that of normal urine. The yield of Glutamic-Oxalacetic Transaminase (GOT) activity is glutamic acid. It was shown that glutamic acid has a significant retardation effect on the precipitation of calcium oxalate stone formation. Therefore it may be suggested that GOT activity involved in glutamic acid creation in situ, has a role in kidney stone formation.
