Abstract

BACKGROUND: Adolescents respond differently to alcohol than adults. Furthermore, binge drinking in young adolescents is becoming increasingly common. METHODS: To determine if the effects of binge drinking on brain damage are different in juveniles compared with adults, the effects of a 4 day binge ethanol treatment (e.g., 4 days of 4 times per day 15% ethanol intragastrically, approximately 9-10 g/kg/day ethanol) were investigated in adolescent-juvenile rats (JVN) 35 days old and compared with adult (ADT) rats 80 to 90 days old. Brain damage was measured by using the amino cupric silver stain of de Olmos et al. (1994). RESULTS: Significant brain damage was found in both groups. The olfactory bulbs were equally damaged in both groups; however, the associated frontal cortical olfactory regions were damaged only in JVN. The anterior portions of the piriform and perirhinal cortices also were damaged only in JVN rats. Quantitation of silver-stained frontal areas in binge ethanol-treated JVN rats ranged from 400% to 1,260% of control values. For example, in anterior perirhinal cortex, silver stain increased from 48 +/- 14 to 444 +/- 114 (mm2 x 10(3) argyrophilic area; p < 0.01) in JVN control and binge ethanol-treated animals, respectively. In contrast, posterior perirhinal cortex showed greater damage in adults, being 236 +/- 76 vs. 875 +/- 135 (mm2 x 10(3) argyrophilic area; p < 0.005) in JVN and ADT, respectively. CONCLUSIONS: The young-adolescent brain shows differential sensitivity to alcohol-induced brain damage compared with adults.

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.
