Effect of alcohol on blood dolichol concentration.

| Abstract |
Serum dolichol levels were studied in 95 active alcoholics and 16 abstinent alcoholics (at the time of blood sampling) and compared to those of 41 social drinkers. Active alcoholics had a significantly higher mean serum dolichol concentration (182.7 +/- 5.1 ng/ml, p less than 0.001 than either abstinent alcoholics (138.7 +/- 5.4 ng/ml) or social drinkers (142.1 +/- 4.1 ng/ml). During weekend (48 hr) heavy drinking (5.5 g of alcohol per kg b.w.) no significant changes were seen in mean serum dolichol concentrations in 10 healthy, nonalcoholic volunteers. Neither did moderate drinking for 10 days (60 g of alcohol daily)--preceded and followed by a period of abstinence--produce any significant changes in serum dolichol levels in 10 nonalcoholic subjects. During detoxification treatment of 12 alcoholics, mean serum dolichol concentration stayed constant for the first 7 days; on entering treatment it was 227.7 +/- 15.0 ng/ml, on the 3rd day 238.5 +/- 15.9 ng/ml, and on the 7th day of treatment 222.6 +/- 18.6 ng/ml. Our results show that as well as increasing urinary dolichol excretion, chronic alcohol abuse also produces increased serum dolichol concentrations. However, contrary to urinary dolichols, serum dolichol levels do not react significantly to heavy drinking lasting for 48 hr in nonalcoholic volunteers. Furthermore in alcoholics increased serum dolichol concentrations do not decrease as rapidly during abstinence as urinary dolichol concentrations do.
