Abstract

Background: Acetaldehyde binds to some proteins, which results in Schiff base formation. It is assumed that acetaldehyde binds to the proteins after the consumption of ethanol, to form an adduct. Such acetaldehyde adducts are related to organ disease. Methods: We examined 8‐week‐old male BALB/c mice, which were given a liquid diet for 7 days. The diet consisted of vitamins, minerals, amino acids, and a 5% (v/v) ethanol solution. After the 7 days, we took tissue samples from the brain, liver, and adrenal cortex to investigate the distribution of acetaldehyde adducts. We performed immunohistochemical staining of the cerebral cortex, liver, and adrenal cortex from the mice by using antibodies against acetaldehyde adducts. Results: Our study showed that acetaldehyde adducts formed in the cerebral cortex in the early phase in alcohol‐fed mice. Conclusions: Because acetaldehyde in the liver has been shown to cause liver damage, our study suggests a relationship between acetaldehyde adducts in the brain and brain damage.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Reactive electrophilic acetaldehyde can strongly induce covalent adduct formation with nucleophilic molecules such as proteins and DNA, forming AA-protein or AA-DNA adducts in the brain.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
