Dihydroergotoxine(Hydergine) and ethanol-induced aging of C57BL/6J male mice.

The residual effects of dihydroergotoxine (Hydergine), ethanol, and Hydergine-plus-ethanol were investigated in old male mice of the C57BL/6J strain. Prolonged 10% v/v ethanol, concomitant with adequate nutrition, produced a significant decrease in life-span, decreased spontaneous locomotor activity and reduced lipofuscin accumulation in neurons of the reticularis gigantocellularis. These effects were not apparent in mice treated with Hydergine or alcohol combined with Hydergine.
