Some Effects of the Continued Administration of Alcohol to the Domestic Fowl, with Special Reference to the Progeny

Ignored Papers, Invented Quotations: A History of Fetal Alcohol Syndrome

Given the high rate of alcoholism throughout history, its effects on the fetus may have existed for millennia. But, the claim that Greeks and Romans were aware of fetal alcohol syndrome rests on incorrect citations. From 1725, maternal alcohol consumption was associated with retarded fetal growth and neurological anomalies. From 1809, scientists followed Lamarck's theory that the disorders parents acquire during their lifetime are passed on to their offspring. Fetal effects were thought to be inherited mainly from the father. During the 19th century, parental alcoholism became associated with malformations. In 1915, Ballantyne distinguished genetic influence via germ cells from toxin's effect on the embryo. Fetal alcohol syndrome was characterized by Rouquette [Influence de la toxicomanie alcoolique parentale sur le développement physique et psychique des jeunes enfants] in 1957 and Lemoine et al. [Ouest Medical. 1968;21:476-482] in 1968 as consisting of 4 features: (A) facial anomalies (narrow forehead, retracted upper lip, and cupped ears), (B) severe growth retardation (prenatal and postnatal), (C) malformations (limbs, cardiac, and visceral), and (D) central nervous system anomalies (hyperexcitability and mental retardation). But, their studies, written in French, remained disregarded. In 1973, Jones et al. [Lancet. 1973;302:999-1001] reported "the first association between maternal alcoholism and aberrant morphogenesis in the offspring." The history of fetal alcohol syndrome reveals shortcomings in citation practice. Alleged quotations remained unverified, non-English publications neglected, and short quotations taken out of context. Prejudiced by religious and abstinence groups, reports on alcohol damage to the unborn were fraught with emotions, moralizing, social implications, and presentism, the interpretation of past events with present knowledge.

Fetal alcohol spectrum disorders: the epigenetic perspective

Ethanol is a classic teratogen capable of inducing a wide range of developmental abnormalities. Studies in animal models suggest that differences in timing and dosage underlie this variability, with three particularly important developmental periods: preconception, preimplantation, and gastrulation. These periods of teratogenesis correlate with peak periods of epigenetic reprogramming which, together with the evidence that ethanol interferes with one-carbon metabolism, DNA methylation, histone modifications, and noncoding RNA, suggests an important role for epigenetic mechanisms in the etiology of fetal alcohol spectrum disorders (FASDs). In addition to a number of testable hypotheses, an epigenetic model suggests that the concept of a "fetal alcohol spectrum" should be expanded to include "preconceptional effects." This proposal has important public health implications, highlighting the urgency of research into the epigenetic basis of FASDs.

THE INFLUENCE OF ALCOHOL UPON THE GROWTH OF SEEDLINGS

In this paper it is shown that if the dry seeds of the cantaloupe (Cucumis melo) are soaked for 3 hours in solutions of ethyl alcohol of concentration ranging from 2 to 16 per cent by volume, and then germinated and grown in distilled water in the dark, the total growth attained is greater by amounts ranging from 9 to 35 per cent than is that made by seeds treated in every way identically except that they are initially soaked in distilled water instead of alcohol. It is shown that this result is not due simply to differences in osmotic pressure in the different alcohol solutions. It is probably due to a simple selective action of the alcohol which eliminates the constitutionally weak and defective seeds.
