Ethyl alcohol was administered to neonatal rats from postnatal day 4 to day 10 during the brain growth spurt via an artificial rearing technique. Groups of rats received one of nine doses of alcohol (0.0, 2.5, 3.3, 4.0, 4.5, 5.3, 6.6, 7.5, or 8.5 g\/kg body weight) administered in 8 hours each day. BACs were determined on postnatal days 6 and 7 at times corresponding to peak and trough BACs, respectively. On postnatal day 10, brains were removed, and total brain weights, cerebellar weights and brainstem weights were measured. Pups receiving 4.0 g\/kg\/day or less had mean peak BACs below 150 mg\/dl and did not exhibit significant microencephaly when compared with controls. Higher dosages further increased the peak BAC and produced significant microencephaly. While a dose of 4.5 g\/kg\/day was sufficient to decrease significantly both total brain weight and cerebellar weight, a minimum dose of 6.6 g\/kg\/day was required for significant restriction of brainstem weight. The dose of 7.5 g\/kg\/day yielded a mean peak BAC of 420 mg\/dl and reduced total brain weight, cerebellar weight, and brainstem weight by 33%, 52%, and 22%, respectively, relative to controls. Exposure to 8.5 g\/kg\/day was uniformly lethal. Peak BAC and total brain weight were highly correlated (r = \u2212.916). As peak BAC increased, total brain weight decreased linearly. Comparisons with previous studies indicate that condensing the daily dose of alcohol effectively reduced the threshold doses for microencephaly and lethality.<\/jats:p>","DOI":"10.1002\/tera.1420370307","type":"journal-article","created":{"date-parts":[[2005,6,11]],"date-time":"2005-06-11T15:07:27Z","timestamp":1118502447000},"page":"223-231","source":"Crossref","is-referenced-by-count":114,"title":["Blood alcohol concentration and microencephaly: A dose\u2010response study in the neonatal rat"],"prefix":"10.1002","volume":"37","author":[{"given":"Daniel J.","family":"Bonthius","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James R.","family":"West","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2005,5,31]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/0376-8716(87)90087-1"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.3758\/BF03326663"},{"key":"e_1_2_1_4_1","first-page":"195","article-title":"Time course of blood alcohol concentration in chronically exposed neonatal rats","volume":"11","author":"Bonthius D.
