Female college students (n = 49) from a small southwestern United States university participated in the 9-month study. Data collected included the assessment of drinking habits and other related substance use habits and serum levels of carbohydrate-deficient transferrin (CDT). Each subject provided an interview and blood sample on three occasions at 90-day intervals. Appended to the interview were a series of questions regarding stage of menstrual cycle and the diagnoses of certain diseases. The CDT values obtained were consistent with those obtained in other studies. Moderate-drinking subjects had significantly higher CDT values than did the abstainers and light drinkers. Females using oral contraceptives had significantly higher CDT values than those who were not taking oral contraceptives. Finally, although CDT values varied over time, they did not appear to vary as a function of menstrual cycle stage.

BackgroundUsing a rat model we have found that the bioflavonoid silymarin (SY) ameliorates some of the negative consequences of in utero exposure to ethanol (EtOH). In the current study our aim was to determine if laterality preference and corpus callosum development were altered in rat offspring whose mothers were provided with a concomitant administration of SY with EtOH throughout gestation.MethodsWe provided pregnant Fisher/344 rats with liquid diets containing 35% ethanol derived calories (EDC) throughout the gestational period. A silymarin/phospholipid compound containing 29.8% silybin was co administered with EtOH to a separate experimental group. We tested the offspring for laterality preference at age 12 weeks. After testing the rats were sacrificed and their brains perfused for later corpus callosum extraction.ResultsWe observed incomplete development of the splenium in the EtOH-only offspring. Callosal development was complete in all other treatment groups. Rats from the EtOH-only group displayed a left paw preference; whereas control rats were evenly divided between right and left paw preference. Inexplicably both SY groups were largely right paw preferring.ConclusionsThe addition of SY to the EtOH liquid diet did confer some ameliorative effects upon the developing fetal rat brain.

We explored the possibility that silymarin (SY), a fraction from Silybum marianum, might protect against the effects of in utero exposure to ethanol upon subsequent social memory function. Three groups of 8 pregnant female Sprague-Dawley rats each were provided with a liquid diet containing 35% ethanol derived calories (EDC). One experimental group received a daily subcutaneous injection of 400 mg/kg SY, the second, a 400 mg/kg oral dose of SY, a third group was maintained on the 35% EDC diet. A fourth group served as the pair-fed control group. The liquid diet regimen was maintained throughout pregnancy. Rats pups were fostered by dams in a fifth group that had been maintained on rat chow. At 90 days the pups were tested for social memory. Social recognition scores recorded for the ethanol pups were significantly poorer than those observed in both SY/ethanol groups and the chow group.
