Immunological Abnormalities and Hydantoins [PDF]

open access: yesBMJ, 1972
Various immunological features were measured in 20 patients with epilepsy who had received prolonged treatment with hydantoins. Immunoglobulin A (IgA) was shown to be absent or low in five patients, beta(1)C/A was low in 10 patients. Five patients showed negative reactions to skin tests, and two could not be sensitized to dinitrochlorobenzene.

New insights in the removal of the hydantoins, oxidation product of pyrimidines, via the base excision and nucleotide incision repair pathways. [PDF]

open access: yesPLoS ONE, 2011
BACKGROUND: Oxidative damage to DNA, if not repaired, can be both miscoding and blocking. These genetic alterations can lead to mutations and/or cell death, which in turn cause cancer and aging.
